By aligning the stabilizing piece 21a with the joint gap when installing the joint cover attachment tool, it is also possible to provide an installation positioning function. In this case, it becomes easy to attach a plurality of joint cover attachment tools in a straight line, and construction becomes very easy. The material is metal,
For example, stainless steel etc. In addition, the locking piece 24 is for locking an engaging piece 28 of a joint cover E, which will be described later, and fixing the joint cover E to the joint part F between the panels B.
In addition, by forming the joint cover fittings in a short shape, even if the joint cover E is removed from one of the joint cover fittings, it will be locked by the other joint cover fittings, so that the joint cover E can be removed. It becomes easy to attach and attach without peeling off. Furthermore, the joint cover E is made of the above-mentioned metal thin plate material, and its shape is as shown in FIG. It consists of a surface 27 and an engagement piece 28 which is bent inward so that the tip of the side wall decorative surface 27 can be engaged with the above-mentioned engagement piece 24. To explain in more detail, the decorative surface part is used to fix panel B on wall base α by fixing joint cover E to joint part F using a joint cover fixing tool as shown in Fig. 1. This is to cover the fixture β and prevent it from being exposed to the outside. In addition, the engaging piece 28 is locked to the locking piece 24 of the joint cover mounting tool, and by fitting the joint cover E to the joint cover mounting tool, the joint cover E can be securely placed on the joint part F. This is to fix it without coming off.

Next, a construction method for forming a joint structure according to the present invention will be explained.
