Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a joining structure for wallboards, and more specifically to a joining structure for wallboards that exhibits elasticity at the joint.

[Conventional technology]

Conventionally, as a prefabricated building structure, supporting columns are made of steel and inorganic wall plates are attached to them.

By the way, as shown in Figure 4, the structure for attaching the wall panels to the support columns is to fix both wall panels B and B butted against each other on the support column A with tapping screws C, and then process the joints with a joint jointer D, etc. things are being done.

However, if the wallboard expands or contracts due to the effects of temperature, humidity, etc., the above mounting structure is mutually fixed rigidly, so as shown in Figure 5, the crack E will enter from the screw fixing part, reducing the fixing strength. There was a problem in which the value rapidly decreased.

Therefore, as shown in Figure 6, two pillars A and A are installed so that the pillars can deform to some extent as the wall plate expands and contracts.
It is conceivable to stand the walls parallel to each other and fix the ends of the wall plates B and B to the pillars A and A, respectively.

[Problems with conventional technology]

However, in the case of the above mounting structure, although some degree of follow-up deformability can be expected at the central portions of columns A and A, the upper and lower ends of column A are fixed to foundations C, C', etc., so complete follow-up deformation will not occur. cannot be expected and cannot be a fundamental solution.

[Problems solved by invention]

In view of the above-mentioned problems, this invention aims to provide a wallboard joining structure in which the mounting position of the wallboard to the support column can be changed even if the wallboard expands and contracts a little, and the mounting strength of the wallboard is also excellent. It was done for a purpose.

[Technology to solve problems]

That is, in the joint structure of the wall boards of this invention, the wall boards are butted against each other on the front side of the support column, and on both sides of the support column, there are bent pieces that are folded back along the back surface of the wall plate on the front side of the support column. A mounting bracket is fixed thereto, the bent piece has a bent portion having a U-shaped cross section on the back surface of the wall board, and an outer edge of the bent portion is fixed to the back surface of the wall board. It is something.

〔Example〕

Next, an example of this invention will be described.

FIG. 1 is a plan view of an embodiment of this invention, and FIGS. 2 and 3 are plan views of other embodiments.

In the joint structure of the wall plates of this invention, the wall plates 2 and 2 are butted against each other at the front 1A of the support column 1 made of C-shaped steel, etc., and the side walls 1B and 1C of the support column 1 are connected to each other at the front 1A side of the support column 1. Mounting brackets 3, 3 having bent pieces 3A, 3A folded back along the back surfaces 2A, 2A of the wall panels are fixed, and the bent pieces 3A, 3A form a U-shaped cross section on the back surfaces 2A, 2A of the wall panels. Bent parts 3B, 3B are formed, and the outer edge 3 of the bent part
C, 3C are fixed to the back surfaces 2A, 2A of the wall plates with screws 4, etc.

In the above embodiment, when the support column 1 is made of C-shaped steel, a mounting washer 1D for the mounting fittings 3, 3 is provided in the opening 1'.

Furthermore, the fixing position of the mounting brackets 3, 3 to the wall plates 2, 2 is L≧, taking into consideration the thickness T of the wall plates 2, 2.
It is said to be 4T.

Although the above embodiment shows the case where the wall plates 2 and 2 are directly butted against each other, a jointer material 5 or a sealing material 6 may be inserted into the butt portion 2B as shown in FIG. 2 or FIG. 3.

[Effect]

In this invention, the wall plates 2, 2 are fixed to the support column 1 via the side parts 1B, 1C and the U-shaped bent parts 3B, 3B of the mounting brackets 3, 3.
The U-shaped bent portions 3B, 3B are deformable and can follow expansion and contraction in the direction of the arrow X with a considerable degree of freedom.

Therefore, the stress on the fixing portion 4 to the wall plate 2 is greatly reduced, and problems such as cracks do not occur.

Further, the fixing position of the screw 4 is sufficiently separated from the end surface of the wall plate 2 by the U-shaped portions 3B, 3B (L≧
4T), it also has excellent crack resistance.

〔effect〕

As explained above, this idea is based on the temperature of the wall plate.
Even if it expands or contracts due to humidity conditions, all of this variation is absorbed by the U-shaped bent part of the mounting bracket, so it is possible to reliably prevent problems such as cracks in the mounting part, and also prevent sudden vibrations. It also has practical effects, such as being suitable as a vibration-resistant structure.
