Description

PREFABRICATED FLOOR PART FOR FLOOR HEATING / OR COOLING, AND ACCORDING TO SYSTEM, FLOOR, METHOD, AND MACHINE FOR THE PRODUCTION OF THE FLOOR PART

The invention relates to a prefabricated floor part for floor heating and / or cooling. In particular, the invention relates to a floor part which comprises a tube for the passage of a heat transport medium, such as water and / or glycol.

Underfloor heating and / or cooling can be realized by pumping a hot or cold medium through a pipe system into a floor of a building, with which the building is subsequently heated or cooled. This pipe system must be laid in the relevant building. The pipe system is, for example, collapsed in the floor. The pipes of the floor heating are connected to a distributor of the floor heating and / or cooling system.

Laying the pipes for underfloor heating is labor-intensive. Moreover, even experienced professionals take the necessary time to lay the pipes.

An object of the invention is to make it possible to lay the pipes for floor heating and / or cooling in a shorter period of time.

This object is achieved with the prefabricated floor part according to the invention, comprising: - a support mat; and - a first tube and a second tube, each comprising a first and second end for connecting to a distributor or other tubes of the floor heating and / or cooling, wherein the first tube and second tube are jointly meandering on the support mat .

The two tubes are provided on the carrier mat in a joint meandering pattern. That is, the two tubes describe substantially the same winding pattern. The two tubes remain at some distance from each other; the tubes do not overlap.

The meandering pattern of each tube comprises a number of parts that extend transversely to the longitudinal direction of the support mat. These tube parts extending in transverse direction are connected to each other via bends in the tube in question, wherein alternately a bend to the right and a bend to the left is provided. The parts of the two tubes extending transversely each have substantially the same distance from each other. That is, the transverse pipe sections of the first pipe are in each case substantially the same distance from the closest transverse pipe section of the second pipe. The center-to-center distance between the tube parts of the two tubes extending in transverse direction is therefore substantially constant.

For example, the center-to-center distance adjacent transverse tube sections of the two tubes is 10-20 cm. This heart-to-heart distance can be selected depending on the desired heat output.

It is noted that the mutual distance between the tubes in the bends of the meandering pattern may deviate somewhat from the constant center-to-center distance, although this is not necessary.

If desired, three or more tubes can be provided in a joint meandering pattern.

Because the floor part is provided as a prefabricated element, the tubes can be installed in one go in the meandering pattern. This saves time during installation.

In use, the two ends of each pipe are connected to a floor heating or cooling distributor. The two ends of the first tube are connected as a first group of the distributor and the two ends of the second tube are connected as a second group of the distributor. The tubes are hereby connected such that the flow of the heat transfer medium through the tubes in use is opposite. As a result, the tube parts of the first tube supplying hot transport medium lie next to the tube parts of the second tube that return cooled transport medium. As a result, the floor temperature is substantially the same everywhere. This is in contrast to conventional systems with a single meandering pipe, in which the floor temperature varies over the floor surface.

This also increases the efficiency of floor heating / cooling. Because floor heating / cooling is more efficient, it is also possible to install more linear meters of pipe systems than in conventional systems. In conventional systems where a single meandering tube is provided, the maximum tube length is around 100 meters. The tube length of each tube, on the other hand, can be around 140 meters with the invention. Since two pipes are used on the support mat, a total gain of 80 linear meters per floor section can be achieved. Therefore, with the floor part according to the invention, a large number of square meters of floor heating / cooling can be laid in a short period of time.

In a preferred embodiment, each of the first tube and the second tube comprises a meandering pattern of alternately a left loop and a right loop, wherein the left loop of one tube is arranged in the left loop of the other tube, while the right loop of the other tube is arranged in the right-hand loop of one tube.

A left-hand loop is understood to mean a first transverse pipe section that is connected via a bend to a second transverse pipe section, the bend being on the left-hand side. It is noted that the bend in the left loop is a bend to the right. Similarly, a right-hand loop is understood to mean a first transversely extending pipe part which is connected via a bend to a second transversely extending pipe part, the bend being located on the right-hand side.

The left loop of one tube is arranged in the right loop of the other tube, so that the joint meandering pattern is formed.

In a further preferred embodiment, one of the left loop and right loop is each time wider than the other loop, in which the narrower loops of the first tube are each arranged in the wider loops of the second tube and the narrower loops of the second tube are each arranged in the wider loops of the first tube.

In this embodiment, a wide left or right loop is alternated with a narrow right or left loop in each tube. With the wider loops, the distance between the transversely extending pipe sections of the respective pipe is greater than the distance between the transversely extending pipe sections of the narrower loops of the same pipe.

Preferably, the distance between the transversely extending tube parts of the wide loops of the first tube is substantially equal to the distance between the transversely extending tube parts of the broad loops of the second tube. Accordingly, the distance between the transversely extending pipe sections of the narrow loops of the first pipe is preferably substantially equal to the distance between the transversely extending pipe sections of the narrow loops of the second pipe. Moreover, the distance between the transversely extending pipe sections of each wider loop is preferably three times the distance between the transversely extending pipe sections of each narrower loop. In that case, the narrower loops can be arranged in the wider loops such that the distance between a transversely extending tube part of the first tube and an adjacent transversely extending tube part of the second tube is in each case substantially equal. This distance in that case substantially corresponds to the distance between the tube parts of a narrower loop extending in the transverse direction.

In a preferred embodiment the floor part can be rolled up. That is, the carrier mat is a roll-up carrier mat, and moreover the tubes can be rolled up together with the carrier mat.

The prefabricated floor part can be rolled out on the floor of a building to form a pipe system for floor heating and / or cooling. The tubes are then already provided in a desired shape, i.e. according to a joint meandering pattern. This saves time during installation.

In a further preferred embodiment, the first tube and the second tube are extorted, preferably with air.

The tubes can be pressed by providing their ends with a suitable valve, so that the pressing medium, such as air or water, is kept in the tubes. The tubes are preferably pressed with air, for example compressed air. By pressing the tubes with air, the weight of the tubes does not increase due to the pressing. Because the tubes are filled with air and sealed, the tubes will collapse less quickly in the rolled-up condition of the floor part. A relatively long floor part can hereby be rolled up, without the tubes being damaged in the rolled up condition by the weight of the rolled up package.

The first tube and second tube are preferably made from a plastic, and more preferably from cross-linked polyethylene, such as PEX-A, or polyethylene with increased temperature resistance, PE-RT.

The manufacture of the pipes from cross-linked polyethylene or PE-RT (“Polyethylene or Raised Temperature Resistance”) allows a mechanical coupling of the pipe with other pipes or a distributor in a simple manner. In particular, the tubes of cross-linked polyethylene or PE-RT can be coupled to other tubes or a distributor of the relevant floor heating or cooling, without heating or gluing the tubes. For example, for connecting the tubes, use is made of a sliding sleeve coupling, for example a compression sliding sleeve coupling, or a crimping ring coupling.

There are different variants of cross-linked polyethylene ("PEX", or also "XLPE"). Peroxidically cross-linked polyethylene ("PEX-A") is preferably used. However, PEX-B or PEX-C can alternatively be used.

The diameter of each of the tubes is preferably 10-32 mm, for example 10, 14, 16, 17, 20, 25 or 32 mm. The wall thickness of each of the tubes is preferably 1-3 mm, for example about 2 mm.

In a preferred embodiment the carrying mat is designed such that the carrying mat can be cut with a hand tool.

Because the carrier mat can be cut with a hand tool, the carrier mat can be shortened to the desired size. Moreover, the carrying mat can be partially cut so that the carrying mat can make a bend. That is, by trimming the carrier mat, a first part of the carrier mat can be placed at an angle with respect to a second part of the carrier mat. As a result, the support mat and the pipe mounted thereon can, for example, be laid in a corner or installed around a pillar of the building. The floor part can thus be placed at an angle of up to 180 degrees. Because the carrying mat can be cut by hand, the floor part can easily be adjusted during installation work.

The trimming of the carrier mat is moreover made possible by the meandering pattern of the tubes. After all, the carrier mat can be cut within a loop of the meandering tubes, without touching a tube.

Incidentally, the tubes can preferably also be shortened, for example with the aid of known tube cutters or tube cutters. Thus, the entire prefabricated support mat can be shortened on site with the aid of hand tools, in order to make the floor part fit on the floor in question. The tubes are preferably made of plastic, so that the tubes can easily be shortened.

The support mat is preferably provided with a flexible material such that the support mat is bendable in both its longitudinal direction and in its width direction.

The carrying mat can be cut with a hand tool. The material of the carrier mat is preferably chosen such and the carrier mat has such a thickness that the force that must be exerted on the carrier mat to cut it is less than 500 N, preferably less than 300 N and more preferably less than 100 N. For example, a side cutting pliers or middle cutting pliers are used for cutting. The support mat can preferably be cut with the aid of a non-electric hand tool.

In a preferred embodiment, the support mat is designed as a metal mesh with a wire thickness of 1-3 mm.

Due to the small wire thickness of 1-3 mm, the carrying mat can be cut with a hand tool. Moreover, with such a small wire thickness, the weight of the carrying mat remains limited. A relatively large floor part can hereby be manufactured and rolled up, without the tubes being damaged by the weight of the rolled-up package.

The mesh width of the mesh of the support mat is, for example, 5-20 cm, preferably 15 cm.

With such a mesh size, the weight of the support mat is further limited, so that the tubes are not damaged by the weight of the rolled-up package.

For example, the metal is a galvanized metal, such as galvanized steel or galvanized iron, or a galvanized metal, such as galvanized steel or galvanized iron.

In another embodiment, the carrier mat is designed as a plastic carrier mat.

For example, the carrier mat comprises polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or chlorinated polyvinyl chloride (CPVC) and / or a plastic film, such as a PE film. The carrying mat can be in the form of a continuous plastic carrier, or as a mesh-shaped carrier of plastic.

In yet another embodiment, the carrier mat is made of rubber, textile, bamboo, reed and / or fiberglass.

For example, the support mat is designed as a mesh-shaped support made of rubber, textile, bamboo, reed or fiberglass, or as a continuous support made of rubber, textile, bamboo, reed or fiberglass.

In a preferred embodiment, the carrier mat is prepared for cutting the carrier mat. For example, the carrier mat is perforated at one or more locations along the entire width direction, so that the carrier size can easily be cut or cut along the perforation line, or can be torn in or torn by hand. The perforation line is preferably provided in a loop of the tubes. For example, a plastic carrier mat, such as a carrier mat of PE or PP, is provided with such a perforation.

In a preferred embodiment the first tube and the second tube are fixed in a path in the longitudinal direction of the support mat, in which the width of the support mat is wider than the path covering the first and second tube, so that an uncovered path is formed next to this path .

In other words, the tubes cover only a part of the width of the support mat, while at least one uncovered part of the support mat is provided in addition to the path covering the tubes. This uncovered part offers space for the passage of pipe parts, for example of other floor parts. The pipe parts that are passed over the uncovered part of the support mat during the installation of the prefabricated floor part can, if desired, be attached to it during the installation.

In one embodiment, at least one end of each of the first tube and the second tube extends from the support mat.

The tubes are attached to the carrier mat at several points, so that the tubes follow the meandering pattern. In this embodiment, however, an end of each tube, i.e. an end part of the relevant tube, is not attached to the support mat, so that this end part can be freely positioned relative to the support mat. This gives the required flexibility during installation. The free end can be used to connect pipes from adjacent floor parts, or to connect the pipes with a distributor.

For example, the first tube and the second tube have a length of 100 - 240 meters.

The invention further relates to a system for laying floor heating or cooling, comprising the prefabricated floor part as described above and mechanical pipe couplings for coupling the ends of the pipes to a distributor or to other pipes of the floor heating or cooling.

With the mechanical pipe couplings, the at least two pipes of the floor part can be connected to a distributor or to other pipes, without having to heat the pipes and without having to use glue. For example, for connecting the tubes, use is made of a sliding sleeve coupling, for example a compression sliding sleeve coupling, or a crimp ring coupling.

The invention furthermore relates to a floor provided with floor heating and / or cooling, provided with a first tube and a second tube, which are jointly provided meandering on the floor, wherein each tube comprises a first and second end connected in such a way to a distributor of the floor heating and / or cooling that, in use, the flow through the first tube is opposite to the flow through the co-meandering second tube.

It is possible to lay the first and second pipe on the floor in the joint meandering pattern during the installation work. Preferably, however, the floor is formed using one or more of the prefabricated floor parts described above, whereby the pipes are already provided in the joint meandering pattern, and the pipe system for floor heating / cooling can thereby be laid faster.

The invention further relates to a machine for producing the prefabricated floor part as described above, comprising: - a supply line for supplying the support mat, which is adapted to transport the support mat in its longitudinal direction; - a first tube supply for supplying the first tube; - a second tube supply for supplying the second tube; - first fastening means adapted to mechanically fasten the first tube on the support mat; and - second fastening means adapted to mechanically fasten the second tube on the support mat.

Because use is made of mechanical fixing, instead of fixing by means of glue or heating, the liquid tightness of the tubes is not affected. For example, the first and / or second means for mechanically securing the tube comprises a braiding machine, a tacker device or a tie-wrap device (English: "cable tie gun" or "cable tie tool").

For example, the carrier mat with the supply line in the unrolled state is transported towards the braiding machine, the tacker device or the tie-wrap device. With the first and second tube feed, the tubes are laid in the joint meandering pattern on the rolled-up carrier mat and then attached by the braiding machine, the tacker device or the tie-wrap device.

For example, the means for mechanically securing the tube comprises an apparatus, such as a tacker, for mounting fasteners, such as staples (e.g. tacker staples) or nails (e.g. tacker nails). The staples or nails are, for example, of metal, but preferably of plastic. The staples or nails clamp the tube onto the support mat, without piercing the tube wall. For example, the staples or nails are U-shaped. A tacker is preferably used in combination with a continuous support mat.

In a presently preferred embodiment, the first and second means for mechanically securing the tubes comprise a braiding machine or tie-wrap device. A braiding machine or tie-wrap device is preferably used in combination with a mesh-shaped support mat. The braiding machine or tie-wrap device attaches the respective tube to the support mat by a braid wire or tie-wrap as attachment means to fit the tube and the grid of the support mat.

In a preferred embodiment, each of the first tube supply and second tube supply comprises a conductor which is arranged transversely to the conveying direction of the support mat, and a diverting mechanism movable along the conductor for guiding the first tube or second tube, respectively.

The tubes are each supplied to the deflecting mechanism which can move back and forth along the guide in the width direction of the support mat, while the support mat can move longitudinally along the deflection mechanism. The conductor is, for example, designed as a rail. Each time a tube is placed on the support mat in the width direction by the corresponding deflection mechanism and is fixed by the fastening means, so that a tube part extending in the transverse direction is attached to the support mat. Subsequently, the support mat is moved in the longitudinal direction over the desired distance, to form a loop of the meandering pattern. The diverting mechanism then moves along the conductor in the opposite direction, so as to form the next transversely extending part of the meander-shaped pattern of the tube in question. This tube part is also attached to the mat by means of the fixing means, such as a tacker, braiding machine or tie-wrap device. This process is repeated, so that the tube in question is attached to the support mat in the desired meander-shaped pattern.

It is noted that the support mat can be supplied to the machine both horizontally and vertically.

For example, the machine comprises a cutting tool for cutting the support mat and / or the tube to the desired length.

Finally, the invention relates to a method for laying a floor heating and / or cooling, comprising: - laying a first pipe and a second pipe on a floor of the building in which the floor heating and / or cooling is laid wherein the first tube and second tube are laid on the floor in a joint meandering pattern; and - connecting the two ends of each tube to a floor heating and / or cooling distributor, such that in use the flow through the first tube is opposite to the flow through the co-meandering second tube.

Preferably, the method comprises laying one or more rollable floor parts as described above, in which the one or more rollable floor parts are rolled up transported to the building in which the floor heating and / or cooling is laid and then rolled on the floor of the building so that a tubular system for floor heating or cooling is formed.

In a further preferred embodiment, the method further comprises extruding the pipes from the one or more floor parts, preferably with air, so that the pipes are pressed during transport of the floor parts rolled up.

In a preferred embodiment, the method further comprises partially cutting the carrying mat of one or more floor parts to lay the relevant floor part in a bend.

In a preferred embodiment, the method further comprises cutting off a part of the support mat and / or one or more tubes for shortening the floor part.

For the system, the floor, the machine and the method according to the invention, the same advantages and effects apply as described above for the prefabricated floor part. In particular, characteristics of the floor part, the system, the floor, the machine and the method can be combined as desired.

Further advantages, features and details of the invention are elucidated on the basis of exemplary embodiments thereof, wherein reference is made to the accompanying figures. Figure 1 shows schematically a prefabricated floor part according to a first embodiment of the invention; Figure 2 shows schematically a prefabricated floor part according to a second embodiment of the invention; Figure 3 illustrates the trimming of the floor part of Figure 1; Figure 4 shows schematically a floor part according to figure 1 or 2 in rolled-up condition; Figure 5 shows schematically an embodiment of a support mat; Figure 6 schematically shows a floor according to an embodiment of the invention; Figure 7 schematically shows an embodiment of a machine for producing prefabricated floor parts in top view; Figure 8 shows the machine from Figure 7 in side view; and - Figures 9A and B show the adaptation of the floor part of figure 1 to two single meandering pipes.

Prefabricated floor part 2 comprises a rectangular support mat 4 (figure 1). A first tube 6 and a second tube 8 are mounted on support mat 4.

In the example shown, the tubes 6, 8 are made from peroxidically cross-linked polyethylene (PEX-A). Alternatively, the tube can for instance be made from PE-RT or another plastic.

In the example shown, tubes 6, 8 each have a length of about 140 meters. Other tube lengths are also possible, although preferably the length of each tube is at most 140 meters. The tube diameter in the example shown is 10 mm, with a wall thickness of 1.1 mm. However, other tube dimensions are also possible.

The end parts 6a, 6b of pipe 6 and the end parts 8a, 8b of pipe 8 are not attached to support mat 4 in the example shown, so that they have some freedom of movement, for example for coupling with other pipes or with a floor heating distributor or - cooling. In the example shown, the ends 6a, 6b, 8a, 8b extend outside the support mat 4, but this is optional.

Prefabricated floor part 2 '(figure 2) largely corresponds to floor part 2 of figure 1. However, in the example shown, ends 6b, 8b are provided on the other side than ends 6a, 8a, while in floor part 2 the ends 6a, 6b , 8a, 8b are provided on the same side.

As shown in Figure 1, tube 6 alternately includes right loops 10, i.e., loops that extend to the right, and left loops 12, i.e., loops that extend to the left.

The right loop 10 includes a bend to the left, while the left loop 12 includes a bend to the right. Similarly, tube 8 includes right loops 14, and left loops 16.

In the example shown, the left loops 12 of the first tube 6 are wider than the right loops 10 of the same tube 6. In particular, the distance between the transversely extending parts A and B of the left loops 12 is wider than the distance between the transverse parts B and C of the right-hand loops 10. For the second tube 8, the right-hand loops 14 are wider than the left-hand loops 16. In particular, the distance between the transverse tube parts D and E is of the right-hand loops 14 wider than the distance between the transverse tube sections E and F of the left-hand loops 16.

In the example shown, the transversely extending parts B and C of the narrower, right-hand loops 10 of the first tube 6 are at a distance 1 from each other. The smallest loops 16 of the second tube 8, ie the left-hand loops 16, also have a center-to-center distance in the shown example between the transversely extending parts E, F with length 1. The wider loops 12, 14 of tube 6 or tube 8, on the other hand, have a center-to-center distance between the transversely extending tube parts of 31. Thus, it is achieved that the distance between the transversely extending parts A, B, C, D, E, F of the tubes 6, 8 is in each case equal to 1. In other words, the tube parts A, B, C, D, E, F extending transversely are parallel to each other, or at least substantially parallel to each other.

It is noted that the alternating pattern of right-hand loops 10, 14 and left-hand loops 12, 16 may, if desired, deviate from the regular pattern described above at the ends of the support mat 4. An example of this is shown in Figure 2, in which on the lower part of carrier mat 4 shown in the figure there is a deviation from the otherwise regular pattern, in that a narrower loop is used twice for tube 6. However, the regular pattern is preferably alternately, wider loops and narrower loops are used over the entire carrying mat 4, as shown in Figure 1.

The carrier mat 4 of floor parts 2, 2 "can be cut. Figure 3 illustrates this for floor part 2. Because the tubes 6, 8 meander together on the support mat 4, the support mat 4 can be cut without cutting the tubes 6, 8. Through the notch 18, a part of the floor part 2 can be rotated through an angle α, for example through 90 °. However, angles of up to 180 ° are possible. This has the advantage that floor part 2 can be quickly and easily adapted to the design of the building in which floor part 2 is placed.

The flexible support mat 4 and the flexibility of the PEX-A pipes 6, 8 make it possible to roll up the floor parts 2, 2 ', as illustrated in figure 4. Preferably, the pipes 6, 8 are made of a floor part 2, 2' pressed with air before being rolled up. To this end, the tubes 6, 8 can first be provided with suitable valves, also referred to as "pressure relief valves" (not shown). Air is introduced into each of the tubes 6, 8, and then the valves are closed. Because the tubes 6, 8 are filled with air and are sealed off, the tubes 6, 8 will collapse less quickly in the rolled-up state. Compressed air is used, for example, so that a slight overpressure is created in tubes 6, 8. For example, the pressure in the extruded tube is 1.01-1.1 bar. However, applying an overpressure is optional.

The support mat 4 is, for example, designed as shown in Figure 5. The support mat 4 is a mesh of galvanized steel wires 20, 22. In the example shown, square meshes are formed. However, other shapes are possible, such as rectangular meshes, triangular meshes or hexagonal meshes. In the example shown, the mesh width is 10 cm by 10 cm. The thickness of the galvanized steel wires 20, 22 is 1 mm. However, other wire thicknesses are possible according to the invention. The wire thickness is preferably a maximum of about 3 mm, so that the carrying mat 4 can easily be cut with a hand tool.

Figure 6 shows an example of a floor 100 which is provided with a tubing system that comprises two jointly meandering tubes 106, 108. In the example shown, the building comprises a pillar 110, around which the tubes 106, 108 are laid, to subsequently continue the meandering pattern. The ends of pipes 106, 108 are connected to a floor heating / cooling distributor 112. Here, the ends 6a and 8b are connected for outgoing flow, and the ends 8a and 6b are connected for incoming flow. As a result, the flow in tube 6 is reversed to the flow through tube 8. In particular, the direction of flow through a tube part Q of tube 6 is opposite to the direction of flow through the nearest tube part R of tube 8. This increases the efficiency of floor heating / cooling.

In the example of Figure 6, the tubes 106, 108 are laid on site in the desired pattern and fixed on the floor. For this purpose, for example, first a support mat is laid on the floor, to which subsequently the tubes 106, 108 are attached, for example with the aid of a braiding machine or a tacker.

According to the invention, however, a pipe system is preferably laid by rolling the floor parts 2, 2 'onto the floor 100 and connecting them to a distributor 112 in a similar manner as described above.

Machine 200 (Fig. 7, 8) comprises a roller 202 for supplying a mesh-shaped support mat 4. For the sake of clarity, the grid of the support mat 4 is not shown in Fig. 7, but support mat 4 is actually mesh-shaped.

The carrier mat 4 is guided from the feed roller 202 to two conveyor belts 204a, 204b. Optionally, a guide roller 203 is provided to guide the support mat toward the conveyor belts 204a, 204b. The conveyor belts 204a, 204b are provided with studs N, so that studs N can hook into the meshes of the mesh-shaped support mat 4 (Figure 8), so as to transport the mesh-shaped support mat 4. The carrier mat 4 is conveyed by the conveyor belts 204a, 204b in the direction of the arrow P, whereafter the carrier mat 4 is rolled up on a roll 206. Optionally, a guide roll 205 is provided on this output side. The guide rollers 203, 205 contribute to keeping the support mat 4 on the conveyor belt.

A sleeve 207 is preferably provided on roll 206, for example of cardboard or plastic, on which the support mat 4 is rolled up (see figure 8). After the completion of the floor part, this sleeve 207 with the floor part rolled up thereon is removed from the roller 206. A new sleeve 207 is then placed to produce a next floor portion.

The first tube 6 is supplied from a roller 208. A rail 210 is arranged above the support mat along which a carriage 212 can move back and forth. The carriage is provided with one or more deflection rollers 214, 216, which position the tube 6 on the support mat 4.

The machine 200 furthermore comprises a tie-wrap device or braiding machine (not shown) for attaching the tube 6 which is laid transversely over the support mat 4 by the guide rollers 214, 216 to the mesh-shaped support mat 4. For example, the tie-wrap device or the braiding machine is also provided on the carriage 212. Alternatively, the tie-wrap device or the braiding machine can also be on the other side of the carrier mat 4 relative to the carriage, so as to to attach the pipe 6 to the mesh-shaped support mat 4.

The carriage 212 with deflection rollers 214, 216 in each case places a part of the tube 6 over the desired width on the support mat 4, the fastening means of the machine 200 securing this tube part to the support mat 4. Then, by rotating rollers 202, 203, 205, 206 and conveyor belts 204a, 204b, the support mat 4 is moved in the direction of arrow P. Thereafter, the carriage 212 moves in the opposite direction about a new part of the tube 6 over the desired width. to place on the carrier mat 4, wherein the device fixing means also fix this part of tube 6 on the carrier mat 4. Thereafter, the support mat is moved again in the longitudinal direction according to arrow P and the cycle starts again to attach tube 6 to the support mat 4 in a meandering pattern.

The second tube part 8 for the floor part is similarly arranged on the support mat 4. The second tube 8 is supplied from a roll 218. A second rail 220, viewed in the direction of transport of the support mat 4, is arranged after the rail 210. Along this rail 220 is arranged in a similar manner a runner 222, which is provided with one or more deflection rollers 224, 226. In a similar manner as described above for the first tube 6, the second tube 8 is laid on the support mat 4 by means of runner 222 after which a (non-shown) braiding machine or tie-wrap device secures the second tube 8 to the support mat 4.

Machine 200 applies tube 6 to the support mat 4 in a pattern of alternatively wider left loops and narrower right loops, while tube 8 is arranged in a pattern of alternately wider right loops and narrower left loops, with the left loops of tube 8 in the left loops of tube 6 are provided and the right loops of tube 6 are arranged in the right loops of tube 8. Of course, this pattern can also be mirrored, so that tube 6 comprises wider right loops and narrower left loops, while tube 8 comprises wider left loops and narrower right loops.

In Figure 7, the machine 200 is in a state, just after the support mat 4 has been moved a distance 3 * 1, to form the wider right loop of tube 8 and the wider left loop of tube 6. The carriages 212, 222 will now be moved to the left or right to complete the wide loops. Subsequently, the support mat 4 is moved over a distance 1, to form the narrower left loop of tube 8 and the narrower right loop of tube 6. In short, the distance between the rails 220 and 210 and the desired distance 1 between the tube parts of tubes 6 and 8 extending transversely are matched to each other, so that the carriages 212, 222 can synchronously make the wider loops and the narrower loops of the tubes 6, 8, respectively.

In machine 200, the carrier mat 4 is transported horizontally along the fastening means. However, it is also possible to arrange the machine 200 such that the support mat 4 is transported vertically along the fastening means. In that case, preferably, the fastening means, such as a tie-wrap device or a braiding machine, are provided on the carriages 212, 222, so that the tubes 6, 8 can be immediately attached to the support mat 4 while the carriages 212, 222 support the tubes 6, 8 on the support mat 4.

A floor part 2 (Figure 9A) has two tubes 6, 8 that meander together. However, the floor part 2 can easily be adapted to two single meandering tubes. That is, the floor part 2 can be converted into a conventional meander shift. To this end, the tubes 6, 8 are cut or cut along line 300 in Figure 9A, wherein two adjacent tube parts of the two tubes 6, 8 extending in the transverse direction are cut. The cut tubes 6, 8 are then connected to each other with two couplings 302, 304, so that an upper tube is formed from end 6b to end 8b and a lower tube from end 6a to end 8a. The tubes thus formed form a conventional meander pattern.

The present invention is by no means limited to the embodiments thereof described above. The requested rights are determined by the following claims within the scope of which modifications are conceivable.
