Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to improvements in wall structures such as buildings. The final treatment of walls such as buildings is done by pasting vinyl sheets etc. on the wall substrate.
In recent years, walls have been formed using panels made of various materials due to design or functional requirements. When forming walls using various types of panels like this, it is not only required that they be easy to construct, but also that they can be easily replaced after construction. There is also a need for a wall structure that is easy to remove.

[Prior art and problems]

As mentioned above, when a wall surface is formed using panels, the panels are usually fixed to the wall base using fasteners such as screws, or directly adhered to the wall base using an adhesive. things are being done. However, in this case, the latter type naturally has the disadvantage that it is not easy to remove after installation, and even in the former type, the head of the fastener is not exposed on the wall due to aesthetic requirements. Because the walls are formed in such a way that it is generally difficult to remove them, there is a problem in that if a part of the wall surface becomes dirty or damaged, it is impossible to partially replace it and large-scale work is required. was. Furthermore, a method of replacing a finishing plate has been proposed in which the finishing plate is removably attached to a wall surface, which is the construction surface, via the finishing plate (see Japanese Patent Publication No. 55-26265). However, in this replacement method, a framework with the other side of the locking tool is removably attached to the back side of the finished board, so the locking tool must be attached and removed when replacing the finished board. First, the work is complicated, and this work is difficult when forming a wall structure using a plurality of divided panels.

[Means to solve the problem]

The present invention solves the above-mentioned problems and provides a wall structure that is easy to attach and detach.The present invention provides a wall structure that is easy to attach and detach, and in which a plurality of horizontal frames are arranged at appropriate intervals at the base of the wall via fixing devices, and the horizontal frames are attached vertically to the horizontal frames. The crosspieces are fixed, and horizontal crosspieces for joints each having a support fold at the upper end and a support recess formed approximately in the center are arranged between adjacent vertical crosspieces via supports. A wall panel is placed between the crosspieces, and a folded convex portion for locking formed on the back surface of the upper end of the wall panel is placed in a recess for supporting the horizontal beam for the joint located above, and a locking portion formed on the back surface of the lower end side of the wall panel.
