Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a joint structure between wall panels that constitute an indoor wall surface by arranging a large number of panels in an existing building frame.

(Prior art) In recent years, when interior work is being carried out after the construction of a building frame, it is often necessary to change the space around the water, for example, a bathroom with a toilet bowl and sink attached to a bathtub, or a toilet bowl and sink for men and women. Spaces for multiple toilets, etc. to be placed side by side require a wide range of construction work, so we will need general-purpose wall panels, special wall panels such as panels with toilet bowls or sinks, etc. that are assembled into units in advance at factories, as well as plumbing and other facilities. It is defined by bringing equipment, etc. into the building, erecting the wall panels as appropriate, installing piping, equipment, etc., and creating a new inner room using the so-called prefabricated method, thereby simplifying construction. There is a tendency.

These pre-fabricated wall panels are made by installing upper and lower stiles horizontally between the left and right vertical stiles along the entire length of the wall covering board on the back side of which a finishing material such as a decorative sheet is pasted on the surface. It is constructed as a flat unit with a suspended base frame.

In addition, the installation of such wall panels involves the installation of a foundation frame consisting of pillars provided apart from the building wall, an upper frame, a lower frame, etc. suspended horizontally between the pillars, and other wall panels built adjacently. It is done for.

For example, wall panels are generally joined to each other by joining the base frames on the backs of the wall panels so that the joints do not appear on the wall surface.

(Problem that the invention aims to solve) Conventionally, the above-mentioned wall panels were joined together by a worker who entered the back side of the wall panel and used bolts, nuts, etc. to fasten the base frames of adjacent wall panels. However, this method of joining requires a working space on the back side of the wall panel, which has the problem of reducing the effective space within the room.

The present invention was developed to solve the above problems, and provides a wall panel joining structure that allows wall panels to be easily joined together by working from the front side of the wall panels, and does not require work space on the back side of the wall panels. The purpose is to provide

(Means for Solving the Problems) In order to solve the problems explained above, the present invention fixes the wall covering to the base frame, which is made by horizontally suspending the upper and lower stiles between the left and right vertical stiles. Adjacent wall panels
In the joint structure between wall panels that joins the wall panels, a joining member having a clamp member is provided on the outside of the stile on the side of the other wall panel of the one adjacent wall panel, and A joining member having an engagement groove that engages with the clamp member from the front side of the wall panel is provided on the outside of the vertical stile on the one wall panel side of the panel.

(Function) According to the above means, since wall panels can be joined together only by working from the front side of the wall panels, no working space is required on the back side of the wall panels that have been erected.
