WO2010082697A1 - Suspended prefabricated flooring panel unit and flooring panel assembly method using the same - Google Patents

Abstract

The objective of the present invention is to form a flooring panel unit having a shape and structure in which the protruding edges of a plastic board which is a lower member are formed to be extended beyond a portion attached to a flooring panel, so that the flooring panel is easily assembled without interference by the protruding edges of the plastic board and, after assembly, the slab level is flush with an adjacent flooring panel within a specific tolerance. In order to achieve this objective, the flooring panel unit (100) comprises an upper member (10) and a lower member (20) wherein the lower member (20) is larger than the upper member (10), the upper member (10) is square or rectangular in shape, and the lower member (20) has a shape that two of the upper members (10) having a square or rectangular shape are superposed, the overlap area (S) thereof has a smaller square or rectangular shape and does not have two symmetrically positioned corners (R). Projections (22) are formed in the entire overlap area (S) and in a protruding edge Q, which is one of the two protruding edges, but not in a protruding edge P, which is the other protruding edge. The upper member (10) is attached by an adhesive (28) to the square or rectangular lower member (20) including the protruding edge P in which the projections (22) are not formed. The protruding edge P and the protruding edge Q have the same width. Since the flooring panel unit is formed as above, the infiltration of moisture into the joints is prevented and the assembled flooring is used semipermanently. Furthermore, assembly is economically efficient because of the simple structure that can be assembled even by an unskilled worker.

Description

Suspension prefabricated floor panel unit and floor panel assembly method using the same

The present invention relates to a suspension prefabricated floor panel unit and a flooring panel (flooring panel) assembling method using the same. More specifically, the floor panel unit for assembling a floor flooring panel, such as a gymnasium and multi-purpose sports hall, and a method of assembly using the same .

Flooring systems, such as basketball courts and multipurpose auditoriums, are mainly made of solid wood, plain plywood, or processed plywood.

The advantage of wood is that it can be used for a long time without decay under the proper environmental conditions. Protection from moisture is the most important environmental condition. It is reported that only 1cm of weathering occurs in 100 years if the bark is peeled off and kept away from moisture.

Wood is a material that can be preserved indefinitely because it will not rot when protected from moisture. The state of preservation of the eighty-four colonies proves this.

How to protect the flooring system from moisture is of the utmost importance.

The present invention seeks to increase the durability of the flooring system by protecting the flooring system from moisture.

The most representative of the prior art that protects flooring from moisture is the Canadian patent WO 02/12653 A1 (published Feb. 14, 2002). According to this patent, the floor panel has a structure in which the floor board as the upper member and the plastic board as the lower member are integrally bonded by an adhesive.

In order to protect the floorboard, which is the upper member, from moisture, a plastic board is attached to the bottom of the floorboard. The protrusion formed at the bottom of the plastic sheet is in direct contact with the concrete floor. Air is circulated to the space formed by the protrusions, and moisture is also circulated together. Water is present in the space where air and water circulate. Outside moisture can penetrate into the space due to convection phenomena, and the water content in the concrete can be eluted out with seasonal temperature changes. On high humidity or rainy days, more water is present in the space.

The patent technology is a structure in which the plastic plate is cut off at the junction where the floor panel and the floor panel are joined. There is a problem in that the water present in the space where the air and the water circulate passes through the disconnection and is in direct contact with the floorboard. When moisture comes into contact with wood floorboards, the rate of decay is faster and the durability is greatly reduced. In areas of high humidity or high rain, the interface problem is even worse.

As such, the plastic board is not connected at the junction between the floor panel and the floor panel, and in the disconnected structure, the floor board of the floor panel is not protected from moisture.

To solve this problem, it is not simply to form a plastic board larger than a floor board.

This is because the floor panel and the floor panel must be assembled, as well as easy to assemble.

In addition, the slab level by the flooring panel should be horizontal within the permissible deviations.

The assembly of the floor panel will be described.

In the Canadian patent floor panel, it is impossible to close the floor board and the floor board assuming that the plastic board has a larger size than the floor board and the protrusions having the same width protrude from four sides. This is because there is no space for the protrusion to be inserted into adjacent floor panels.

Projections should be formed only on two adjacent sides of the floor panel to make room for the projections to be inserted into adjacent floor panels. There is a problem in this case as well. Since the front surface of the bottom of the plastic plate is formed with protrusions contacting the concrete floor, when the plastic plate of the adjacent floor panel is placed on the protrusion, the protrusions of the bottom part of the plastic plate are placed so that the slab level of the floor panel is the same. Not only does not have a problem to form a plane, but also the gap between the plastic plate overlaps the height of the protruding protrusions to be a problem that does not protect the floorboard from moisture.

The present invention forms a protruding portion of the plastic plate, which is a lower member, beyond the junction with the floor panel, and at the same time, the assembling of the floor plate does not interfere with the assembly of the floor panel, and is easy to assemble, and the adjacent floor panel after the assembly. The purpose is to form a floor panel unit having a shape and structure such that the slab level of the surface becomes a horizontal plane within the allowable deviation, and another purpose is to protect the flooring system from moisture by assembling the floor panel unit. .

Conventional floor panels have a problem in that the floor boards cannot be protected from moisture because the plastic board is disconnected from the floor panel joint. To solve this problem, the protrusion of the plastic plate should be formed long beyond the junction.

However, the formation of the protruding portions of the plastic sheet does not make it possible to assemble the floor panel nor to facilitate the assembly.

To this end, the present invention is a floor panel unit having a structure in which a joint is not disconnected under the premise of forming a protruding portion in a plastic plate, and thus the assembly is easy.

The structure of the floor panel unit 100 of the present invention will be described in detail with reference to the accompanying drawings.

The floor panel unit 100 includes an upper member 10 and a lower member 20. The upper member 10 and the lower member 20 are integrally attached by an adhesive 28. The lower end of the lower member 20 is formed with a protrusion 22 in contact with the concrete bottom surface 40.

The upper member 10 is made of solid wood or general plywood, processed plywood, the lower member 20 is made of synthetic resin, polyethylene, polymer engineering plastics and the like.

1) the shape of the floorboard which is the upper member 10

The shape of the floorboard is square or rectangular. For the convenience of work, it is desirable to be manufactured in a size of 0.6m × 0.6m. It can also be manufactured in other sizes.

2) The structure of the plastic plate that is the lower member 20

Since the lower member 20 is a member that serves to protect the floorboard, which is the upper member 10 from moisture, the floorboard 20 should not be in contact with the floorboard.

To this end, the plastic board as the lower member 20 covers the entire floorboard area of the floor panel unit 100, and at the same time, the junction between the floor panel unit 100 must also be covered by the plastic board.

In order to have a structure in which the plastic plate covers the joint between the floor panel units 100, the plastic plate should be formed larger than the floor board. However, increasing the plastic plate does not enable assembly of the floor panel unit. The plastic plate should be large, but be able to be assembled with the adjacent floor panel unit 100.

Floor panel unit 100 of the present invention is to be assembling and to have a shape of a plastic plate of an easy structure without being disconnected.

This will be described as follows.

By the way, since the shape and size of the lower member 20 is determined according to the shape of the floorboard which is the upper member 10 will be described here with respect to the square floorboard for convenience of description. This is because the same concept as the square is established even when the floorboard is rectangular in shape.

Therefore, in the claims, the description of the claims will be described as a square for convenience. As described above, the technical description based on the square floorboard may represent the technical features of the present invention much better than the rectangular description, and the technology of the present invention becomes clear.

 end. Shape of Floorboard as Upper Member 10

The shape of the floorboard can be square or rectangular. For convenience of explanation, as shown in FIG. 2, the shape of the floorboard is square.

The shape of the floorboard is square (a × a), and the grooves 14 are formed on two sides of the floorboard, and the protrusions 12 are formed on two sides corresponding thereto.

 I. Shape of plastic plate, which is the lower member 20

The thickness t of the plastic sheet is thinner than the floorboard.

The plastic plate is formed to be larger than the floorboard, and has a protrusion P extending in only two adjacent sides, and a corner portion R of the protrusion P is omitted.

In other words, the shape of the plastic plate, which is the lower member 20, is square (axa) including two adjacent protrusions (P), and square (axa) including two adjacent protrusions (Q) is square (sxs). The shape shares S with each other. The square (a x a) here is the same size (a x a) as the floorboard.

 All. Relationship between the protrusion P and the protrusion 22 of the plastic sheet

The protrusion part 22 of the plastic plate lying on the concrete bottom surface 40 forms a space part, and air and moisture circulate by this space part.

The protrusions 22 are not formed on both of the protrusions P and Q of the plastic sheet. The protrusion 22 is formed on one protrusion Q, but the protrusion 22 is not formed on the other protrusion P.

Since the protrusion P and the protrusion Q are portions overlapping each other when assembling the floor covering unit 100, the protrusion 22 is removed from one side.

As shown in FIG. 6, the protrusion P and the protrusion Q overlap each other. Since the overlapping portion is higher than the thickness of the non-overlapping portion by the thickness of the plastic plate, the height of the overlapping portion Q, the outermost protrusion 220, h ₁ , of the overlapping portion Q is lower than the height of the protrusion 22 by t. Formed. For close contact with the slab level of the floor panel unit 100 and the junction.

In addition, as shown in Fig. 7, an inclined surface 22b was given to the “outermost protrusion 220” of the protrusion Q. The inclined surface 22b is an inclined surface formed by the height h ₁ of the protrusion 220 and the height h _{2 of the} protrusion 220. The angle of inclination is 2-3 degrees.

The plastic sheet is inclined to prevent it because it is sag down from the end of the protrusion Q due to the nature of the material. The role of the inclined surface is to close the protrusion Q to the protrusion P to prevent moisture from contacting the joint surface.

 la. Location of floorboards on plastic board

The position where the floorboard rests on the plastic board is located in the square a x a including the area where the projection 22 is not formed in the protrusion P of the plastic board.

The protrusion part 22 is formed in the protrusion part Q of the plastic board on which the floor board is not placed. It is this protrusion Q that is placed on the concrete floor 40 to extend without breaking the joint.

Positioning the floorboard on the plastic plate and attached integrally by the adhesive 28 becomes the floor panel unit 100 immediately.

 hemp. Assembly relationship of floor panel unit 100

Only the protrusion Q of the floor panel unit 100 has a structure in which the protrusions 22 are formed. Since the protrusions P are already provided with floorboards, they are not protrusions P from the perspective of the floor panel unit 100. The protruding portion Q and the extended edge portion R are omitted from the plastic plate.

Looking at the relationship between the slab level and the edge (R) at the point O is assembled four floor panel unit 100 as shown in Figure 2 as follows.

If the edge portion (R) is not omitted, four protrusions (Q) overlap at the point O. In this case, since the protrusions P are placed on the protrusions Q on each side except the edge portion R, only the protrusions P and the two protrusions Q overlap. In other words, the corner portion R overlaps four layers, and in other portions, the two layers overlap, so that the slab level is different from each other.

As in the present invention, when the edge portion R is omitted from the protrusion Q, the overlap at the O point becomes two layers, so that the slab level is the same. This is why the edge portion R is omitted in the protrusion Q of the present invention.

Furthermore, since the protrusions 22 are formed on the protrusions Q, and the protrusions 22 are not formed on the corresponding protrusions P, the protrusions P are easily mounted on the protrusions Q and are closely attached to each other. do.

 bar. Shape of the protrusion 22 formed on the plastic plate

The shape of the protrusion 22 formed on the plastic plate may be a shape of the circular protrusion 22 as shown in FIG. 1 or the shape of the protrusion 221 in which two straight lines are arranged as a pair as shown in FIG.

The shape of the protrusion part 22 is not limited as long as it is such a protrusion part 22 having a strength capable of supporting the upper load while forming a space part that can facilitate circulation of air and moisture. Any projection 22 having such a concept is included in the present invention whatever its shape.

3) slab level

In order to facilitate the installation of the floor panel unit 100, it is preferable that the concrete floor 40 is at a horizontal level. If the concrete floor 40 is at the horizontal level, the assembly of the floor panel unit 100 is easy.

However, there is a case where the concrete floor 40 does not achieve a horizontal level. In particular, when the concrete floor surface () is inclined in one direction or inclined in two or more directions, the assembly of the floor panel unit 100 becomes difficult. In this case, leveling kits should be used for leveling. This is because the contact portion where the four floor panel units 100 meet in one place is sensitive to a slight level error and thus is not easy to assemble.

The position where the leveling kit is inserted is the bottom of the lower member 20 of the floor panel unit 100. The shape of the leveling kit is the same shape as the lower member 20 having the protrusion 22. However, since the lower member 20 is a flat plate having a large size, the leveling kit differs only in that it is a flat plate of a small piece since the lower member 20 is a member. The protrusion 22 of the lower member 20 is inserted into the insertion groove of the protrusion 22 of the leveling kit so that the lower member 20 and the leveling kit form a solid body.

4) Dustproof Rubber Plate

The anti-vibration rubber plate 30 is installed in whole or in part on the concrete floor 40 and then installs the floor panel unit 100 thereon. The anti-vibration rubber plate 30 is a member that cushions the flooring system to improve the performance, protects the joints of the players, and also provides a dustproof function to the sports flooring system.

The anti-vibration rubber plate 30 is a type of vibration control device that provides a function of stabilizing a system by distributing a partial and instantaneous impact load generated from a player (from a jump, etc.) evenly throughout the system.

The present invention forms a protruding portion of the plastic plate, which is a lower member, beyond the junction with the floor panel, and at the same time, the assembling of the floor plate does not interfere with the assembly of the floor panel, and is easy to assemble, and the adjacent floor panel after the assembly. Since the floor panel unit has a shape and structure in which the slab level of the surface becomes horizontal within the allowable deviation, there is an effect of protecting the floor board from moisture.

By protecting the floorboard from moisture, durability is increased, and thus the floorboard panel can be used semi-permanently.

By inclining the outer protrusions of the protrusions of the lower member, the protrusions are in close contact with the adjacent plastic plates, thereby protecting the joint from moisture.

In addition, since the structure of the floor panel unit is simple, even the unskilled workers can be easily assembled, the assembly work is an economical useful invention.
