Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a connection structure for architectural boards used as the ceiling and walls of a chamber.

[Background technology] Regarding the connection of construction boards as described above,
The construction board 1 is fitted into both sides of the jointer 2 using a joiner 2 with a cross-section as shown in the figure, and the construction board 1 shown in FIG. 4 is used.
There are two types of construction, one is called a butting construction in which caulking 4 is interposed between the two. However, with the former, there is a problem with the waterproofness between the joiner 2 and the building board 1, and with the latter, the width of the joint must be adjusted, and the building board may warp due to expansion and contraction of the building board 1. There is a risk of cracking or cracking. Moreover, in either case, there is a problem in that variations in the thickness of the building boards 1 appear on the front side, resulting in surface level differences between adjacent building boards 1.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to not only have good waterproofness but also to eliminate the need for adjusting the joint width.
In addition, it does not cause warping or cracking of architectural boards.
Furthermore, it is an object of the present invention to provide a connection structure for building boards that can absorb variations in the thickness of building boards and reduce surface steps.

[Disclosure of the invention] However, the construction board connection structure according to the invention is as follows:
A jointer having a groove formed in each opposing side end surface of a pair of adjacent construction boards, and having an Ω-shaped cross section and a pair of fitting pieces on both sides that fit into the grooves, and this joiner. It is characterized by a gasket that is fitted into the groove between the fitting pieces of the construction board and makes elastic contact with the surface side of the construction board in each groove of the construction board or the edge of the opening on the front side. At the same time as the construction boards are connected, this jointer is not exposed on the surface of the construction boards, but a seal for waterproofing appears between the two construction boards, and the jointer is attached to the joiner. It is designed so that it can be fitted into a groove provided in it.

The present invention will be described in detail below based on the illustrated embodiment. As shown in FIG. A shallow groove 9 is provided at the side end portion of. The jointer 2 fixed to the mounting surface of the construction board 1 has an L-shaped fitting piece 6 whose tip protrudes laterally, and the pair of fitting pieces 6 are arranged in opposite directions. It is provided so as to protrude, and a groove 8 for attaching the gasket 3 is formed between both fitting pieces 6. The packing 3 housed in the groove 8 has protrusions 7 protruding from both sides of its surface, and a protrusion 10 from the center of the surface.
This is what makes it stand out.

When connecting a pair of adjacent building boards 1,
First, the joiner 2 is fixed to the surface to be attached, and the gasket 3 is fitted into the groove 8 of the joiner 2. Then, each of the fitting pieces 6 of the joiner 2 is fitted into the groove 5, and both building boards 1 are arranged. The fixing piece of the joiner 2 to the mounting surface fits into the groove 9 of one of the construction boards 1.
Thus, the pair of protruding pieces 7 of the packing 3 come into elastic contact with the front surface of the groove 5 in each building board 1, and the protruding pieces 10 come into elastic contact with the side end faces of both building boards 1. Therefore, the two building boards 1 are connected by the joiner 2, and at the same time, a joint is formed between the two building boards 1 by the packing 3, and the packing 3 performs waterproof treatment. In addition, since the packing 3 pushes up both building boards 1 toward the surface, even if there is variation in the thickness of both building boards 1,
Since the grooves 5 are processed on the construction board 1 based on the surface thereof, no steps will appear on the surface, and furthermore, the expansion and contraction of the construction board 1 will be prevented.
Building board 1 to be absorbed by packing 3
No warping or cracking will occur.

FIG. 2 shows another embodiment. The jointer 2 here does not have a fixing piece as in the above embodiment, but the bottom surface of the groove 8 is fixed to the surface to be attached, and the gasket 3 disposed in the groove 8 has a cross-sectional shape. has a rectangular shape, and both shoulders on the front side come into elastic contact with the opening edge on the front side of the groove 5 of the architectural board 1. In this case as well, the same effects as in the above embodiment can be obtained.

[Effects of the invention] As described above, in this invention, there is no need to adjust the joint width in order to connect adjacent building boards using a jointer, and moreover, this jointer can connect the mating pieces. It fits into the groove formed on the side end face of the construction board, and the gasket is in elastic contact with the surface of this groove on the front side of the construction board or the opening edge on the front side, so it is good. It also provides excellent waterproofing properties, and also absorbs the expansion and contraction of building boards and variations in thickness, so there is no warping or cracking of building boards, and the surface of adjacent building boards does not change. There is no difference in level. In addition, the padskin only needs to be fitted into the groove of the jointer, and once the jointer is installed, the padskin elastically contacts the specified location of the construction board and exhibits waterproof properties, simplifying the connection work. This is something that can be done.
