Support and construction for facade panels in a curtain wall and curtain wall

[0001] The present invention relates to a curtain wall.

[0002] More specifically, the invention relates to curtain walls that mainly consist of glass facade panels that are placed in a construction consisting of vertical elements, called posts and horizontal elements, called rails.

[0003] In the case of relatively high weights of the facade panels and / or with fire-resistant curtain walls, the posts and rails are connected together by cruciform supports that are fixed to a pole and of which two wings are fixed to rails, and if necessary gravitate on the front of the rails, for example in a support structure made of aluminum profiles.

It is understood that such supports can also be constructed with a wing for use with posts that only have rails on one side.

[0004] The facade panels, for example, glass panels that can be relatively heavy, then gravitate on the supports, which transmit the weight of the facade panels to the posts by means of the rails.

[0005] Such supports are known from DE 19854203; DE29912697 and EP 1460191, for example.

[0006] However, such supports and constructions for curtain walls that make use of these have a number of disadvantages.

[0007] For example, the supports with the rails to which they are connected, can be folded by the weight of the supported facade panels.

This can lead to a rail touching the underlying facade panel, which can be damaged.

[0008] One solution to this is to use deeper rails, that is, rails that extend over a greater horizontal distance, which is aesthetically unattractive and, of course, more expensive due to an increased use of materials.

[0009] The deeper rails also have only a limited effect on the stiffness of the rail, because while the dimensions of the rails are in fact larger in the horizontal direction, these are hollow profiles generally so that the stiffness in the vertical direction only increases to a certain extent, while folding in the vertical direction.

[0010] Another solution is described in US4428171, where the wings have upward and downward reinforcing ribs to make them stronger, but are still connected to the rails.

[0011] The wings of the traditional supports cannot be made more rigid by giving them a higher height, because the height is limited by the vertical distance between two facade panels, which must be kept small.

[0012] The purpose of the present invention is to provide a solution to the aforementioned disadvantages, among others, by means of a curtain wall, as defined in claim 1.

[0013] In practice, this means that the rail does not have a bearing function for the vertical forces exerted by a facade panel, but that these forces are transferred directly to the posts by the supports.

[0014] As a result, the wings of the supports can possibly be folded slightly by the weight of the facade panels, without this folding being transmitted to the rails.

[0015] Preferably, here the wing is essentially T-shaped, seen in the vertical cross-section, whereby the reinforcement rib is formed by the head of the T.

[0016] For reasons of clarity, it should be noted that this is a T turned at 90 °.

[0017] Thus, this implies that the reinforcement rib extends up and down.

In practice, this reinforcement rib, after the construction of the curtain wall, must be along the facade panels, so that a part of the wing can be at a lower height between the facade panels, because The vertical distance between the facade panels must be kept small.

[0018] In a preferred embodiment, the components of the construction are designed so that the wing can move relative to the rail, whereby a movement in the vertical direction over a minimum distance is possible.

[0019] Thus, this means that the wing and the rails are not designed to be connected, for example, due to a complementary shape or by installations for coupling means.

[0020] In another preferred embodiment of the construction, the rail is provided with a detail for a joint at the upper and / or lower edge, whereby the detail or details are at least partially above or below and around of the reinforcement rib.

[0021] As a result, standard joints can be used to seal the space between a facade panel and a rail, while there is however a chamber for the reinforcement rib.

[0022] In another preferred embodiment, the construction also comprises a threaded profile, whereby the threaded profile and rail have a partially complementary shape so that the threaded profile can be inserted into the rail.

[0023] As a result, it is possible to use a rail without a protruding ridge or protrusion, but which nevertheless has a good grip point for screws of a grip profile.

As a result, the rails can be made to the desired size more easily, because it is not necessary to remove a part of the protuberance.

[0024] When such a threaded profile is made of plastic, it can also act as a threaded and insulating profile at the same time.

[0025] The reinforcement rib of the wing, seen in the horizontal direction, is at least partially between the rail and each of the two facade panels located on top of each other.

[0026] With the intention of better showing the characteristics of the invention, a preferred embodiment of a construction, including a support, for the construction of a curtain wall, according to the invention, and its use are described hereafter by means of an example, without some nature of limitation, with reference to the attached drawings, where:

Figure 1 shows an exploded view of a traditional pole construction with two rails for a curtain wall;

Figure 2 shows a cross section of the construction of Figure 1 according to line II-II in another final state;

Figure 3 shows a perspective view of a part of a construction according to the invention in a situation where the construction is partially constructed;

Figure 4 shows the construction of Figure 3 in another advanced state of construction; Figure 5 shows a cross section of the construction of Figure 4 according to the V-V line; Figure 6 shows a support according to the invention;

Figure 7 shows an alternative construction according to the invention; and Figure 8 shows the detail indicated by F8 in Figure 7 on a large scale.

[0027] The part of a wall 1 shown in Figures 1 and 2 mainly consists of a post 2, made of a hollow aluminum pole profile and two rails 3, made of hollow aluminum rail profiles, which are fixed together .

It is understood that the entire curtain wall 1 comprises a large number of such posts 2 and rails 3.

[0028] The post 2 and rails 3 are provided with details 5 on two edges where the joints 6 are adhered so that they can seal the openings between the post 2 and the rails 3, on the one hand, and a facade panel 7, for example, a glass panel, on the other hand.

[0029] The rails 3 are provided with a protrusion 8, which is a double crest 9 with a narrow groove 10 between them.

The protuberance 8 protrudes out of the rails 3 in the direction of the facade panel 7.

[0030] A cruciform support 11 is fixed to the post 2 and rails 3, which mainly consist of a body 12 that is fixed to the post 2 by bolts 13 and two wings 14 that are fixed to a rail 3 by bolts 14.

In this case, but not necessarily, the support 11 is made of steel, but it could also be made of aluminum or other metal.

[0031] A facade panel gravitates on a wing 14 of a support 11 by means of a small support block 15 and this wing 14 successively gravitates partially on the protuberance 8 of the rails 3, and partially gravitates on the post 2 by means of the body 12.

[0032] An insulator 16 adheres to the protuberance 8 between two facade panels 7 located one above the other, which counteracts the circulation of air in the space between two facade panels 7 and, thus, increases the

insulating properties of curtain wall 1.

[0033] The transition between two facade panels 7 is covered by a grip profile 17 of two parts screwed into the insulator 16 and the protuberance * 8.

This grip profile 17 fixes facade panels 7 in front of the rails 3, so that the facade panels are well fixed in the construction of rails 3 and posts.

[0034] Because the rails 3 are folded by the weight of the facade panels 7, there is a risk that the rails 3 touch the underlying facade panel 7, in the middle between two posts 2, which can lead to hurt

Thus, when the curtain wall 1 is designed, particular attention should be paid to the rails 3 that are designed with sufficient rigidity.

[0035] The maximum vertical distance between two facade panels 7 is defined by the height H of the rails 3 in combination with the coating, fixed by standards, between the grip profile 17 and a facade panel 7 and a small clearance To prevent contact.

Here it is not desired to increase the height H of the rails 3 with respect to the unwanted visual impact thereof.

[0036] It is clear that in this traditional curtain wall, the maximum height A of the wing and thus its stiffness are limited by the maximum vertical distance between two facade panels 7.

[0037] A wall 1 which is composed of a construction, according to the invention, as shown in Figures 3 to 6, differs as follows from the traditional curtain wall 1 described above.

[0038] The support 11 is constructed so that only the body 12 contains holes 18 for fixing the support 11 to the post 2.

The wings 14 are not designed to be connected to the rails 3.

The result is that support 11 is then only fixed to post 2.

[0039] To make room for this support 11 a part of the protuberance 8 is ground.

[0040] The wings 14 of the support 11 are provided with a reinforcement rib 19, which extends over the length L of the wing 14 and protrudes below and on the part 20 of the wing 14 on which the facade panel 7 gravitates.

Due to its height A, the reinforcement rib 19 provides effective resistance against vertical folding of the wing 14.

[0041] The wings 14 have a cross section that is in the form of an inclined T, whereby the reinforcement rib 19 forms the head of the T.

[0042] The rails 3 are constructed with an in-depth section 21 which is located between the details 5 for the joints 6.

This deep section 21 provides space for the reinforcement rib 19, so that the reinforcement rib 19 has a height A that is greater than the maximum vertical distance between two facade panels 7, whereby the reinforcement rib 19 is between rail 3 and facade panel 7.

[0043] As can be seen in Figure 5 in particular, the details 5 for the joints 6 fit widely around the reinforcement rib 19, so that this reinforcement rib 19 can move freely between the details 5 for the joints 6, at least over a certain distance.

[0044] As shown in Figures 4 and 5, in this case the construction is arranged of an extension piece 22 that is mounted on the support 11.

To this end, this extension piece 22 and the support 11 are provided with holes 23 where the bolts can be adhered.

With this extension piece 22 an enlarged support surface for a facade panel 7 is obtained.

[0045] As a result, with a size of support 11 and several sizes of extension pieces, many different thicknesses of facade panels can be supported.

Thus, it is not necessary to make and maintain a raw material of a number of relatively complex and therefore expensive sizes of the supports 11.

[0046] The extension piece can also act partially as an insulator, depending on the material from which it is made.

[0047] In this construction, the weight of the facade panels 7 is transmitted directly to the posts 2 by means of the supports 11, without this weight being transmitted to the posts 2 by means of the rails 3.

[0048] The construction shown in Figures 7 and 8 differs from the construction of Figures 3 to 6 because the rail profiles where the rails 3 are made are not constructed with a protrusion 8.

[0049] Instead, the deepened section 21 is constructed as a cut-out groove that allows the insertion of an enronched profile formed of complementary aluminum 24 therein, where the screws with which the grip profile 17 is fixed can be grasped.

5 As a result, a traditional plastic insulator can be used.

[0050] Alternatively, for better insulation properties, this could also be a combined threaded / insulated profile that is made entirely or partially of plastic.

10 [0051] As a result, it is not necessary to remove any part of the bulge 8, but the space between the panels

The facade 7 is filled with a separate threaded profile 24 over the necessary distance, which makes it easy to make the rails 3 at a size of rail profiles.

[0052] The present invention is not limited to the embodiments described as an example and shown in the drawings, but a support, construction and curtain wall, according to the invention, can be made in all types of shapes and dimensions without move away from the scope of the invention, which is defined by the appended claims.
