Abstract

PURPOSE: To enable the fixation of a panel without using screws so as to simplify the execution by providing a locking edge 1 directed inward in the back surface of a panel, and forming an engagement part, in which the locking edge is to be inserted for fixation, so as to be freely moved on a fixed edge of a barrel edge. CONSTITUTION: The upper end of a panel has a male type projecting edge 1 directed upward and two locking edges 2 respectively having a burr in the tip thereof directed inward, and the lower end of the panel has an inverted-U shape female type connecting part 3, in which the male type projection 1 is to be inserted. A fitting tool 6 as a bridge element for fixing the panel can be freely moved on a barrel edge 4 in the vertical direction without a fall-out, and fixation thereof is unnecessary, but plural fitting tools 6 can be fixed to a building frame by a fixture such as nails and screws. The locking edge 2 of the back surface of the panel is inserted into the engagement part of the fitting tool 6, and while the female type connecting part 3 of the panel is fitted on the male type projecting edge 1 of the panel of the lower stage.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel.

[0002]

2. Description of the Related Art When a long plate-shaped panel is installed in a building, its fitting portion is directly fixed to the outside of the building body using a fixed odor such as nails or screws, which takes time and labor.
In addition, the head of the fixture is exposed on the outer surface, and there is a big problem in the design of the surface. Therefore, a method of constructing a joint cover in order to hide the head of the fixing tool is also used, but its appearance is never aesthetically pleasing. Furthermore, the expansion and contraction of the panel due to the outside temperature causes a wavy phenomenon on the surface, which not only looks bad, but in the worst case it may lead to a peeling accident. On the other hand, as a method that does not use a fixture, there is a method that uses a fixture, but in both of them, since the attachment part is fixed, only a certain joint width can be set,
In addition, in the worst case, a slight misalignment at the time of mounting the mounting tool may make it impossible to carry out the mounting work, and the mounting tool may have to be mounted again and again.

[0003]

The problems to be solved are to simplify the construction of panels, improve the surface design after construction,
It is to prevent deformation and to cope with a slight deviation in joint width.

[0004]

In order to solve the above-mentioned problems, the present invention provides an inward locking side on the back surface of the panel, and an engaging portion for inserting and fixing the locking side is provided on the furring strip fixing side. Made movable. Further, the connection between the panels is made to be a male and female insertion type so that expansion and contraction can be absorbed.

[0005]

1 shows a building panel according to the invention. In other words, the upper edge has a protruding edge that goes upwards,
It has two locking sides with burrs at the tip facing inward, and has an inverted U-shaped female connection part for inserting connection with the protruding side at the lower end side. ing. 6 is an example of a fixture for fixing this panel. The fixture can move freely up and down on the furring strip of 4 and does not fall off, so there is no need to fix it, but it is necessary for the building frame. A plurality of fixtures may be fixed with a fixture such as a nail or a screw. The engaging side of the back surface of the panel is inserted into the engaging portion of the fixture, and the female side connecting portion of the panel is fitted to the male protruding side of the lower panel.

[0006]

As described above, the construction panel of the present invention can be fixed without using screws or the like, which simplifies construction. Since it is fixed to a fixture that can move up and down, there is flexibility on the entire wall surface, and it can be installed without any problems even if there is some misalignment. Since it absorbs the distortion of the wall surface, peeling can be prevented. In particular, the connection between the panels is a plug-in structure, so the expansion and contraction due to thermal deformation is absorbed, and a smooth wall surface is always maintained.
