Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is used for a building such as a house or a store, which can be used as an interior / exterior material such as a flooring material or a wall material for construction with a blind nail. It concerns the improvement of the panel.

[Conventional technology]

Conventionally, as a building panel of this kind, a backing plate having the same shape on the back surface of a square surface decorative plate is pasted and integrated in a state in which a desired dimension is shifted in a diagonal direction of the surface decorative plate,
This backing plate forms a male part and a female part, and as described in Japanese Utility Model Publication No. 62-43074, the four sides of a backing plate that is attached integrally to the back surface of the surface decorative plate. The end face is provided with a concave portion that is recessed inward and a convex portion that protrudes outward with respect to the end face of the surface decorative plate, and there is a convex portion at one corner portion, and the corner angle that diagonally opposes this convex portion. The part may be a panel or the like formed so that a recess is present.

Then, at the time of construction, the male part or the convex part of the other panel is fitted into the female part or the concave part of the one panel nailed by using the male part or the convex part to sequentially join in the plane direction. However, floors and wall surfaces are formed.

[Problems to be solved by the device]

However, in the building panel as described above, the corners of the surface decorative plate in the four corners where chipping is most likely to occur are in a state of protruding from the female parts or recesses of the backing plate, or even the backing plate. During transportation and other handling, since the corners are projected from the corners of the surface decorative plate and only one of the surface decorative plate and the backing plate is present. Such protrusions are likely to be lost due to collision with other objects during construction or construction, especially when the surface decorative plate is made of a hard and fragile material such as natural stone, ceramics, artificial marble, etc. There is a problem in that it is more likely to occur and cannot be used.

However, if such a corner of the surface-coated plate is chipped or a protrusion of the backing plate is chipped or crushed, the protrusions are used as a reference during the construction, and the panel is then fitted. Misalignment occurs between the abutting end surfaces of the parts, and joints for tensioning the panels are distorted or lifted up, which makes beautiful construction impossible.

Further, since the backing plate does not have a reference surface corresponding to the front plate, it is easy to deviate from the reference line such as black ink at the time of construction.

Furthermore, in natural materials, etc., the surface pattern of the surface decorative plate has directionality, so it is necessary to match the pattern patterns of adjacent panels, but in the above panel, one panel was rotated ± 90 ° in the plane direction. In this case, the male and solid parts may be in contact with each other and construction may not be possible, or even if the panels are staggered, the corners of the other panel cannot be aligned with the center of the other panel. There was a problem.

The present invention aims to provide a building panel that solves such problems.

[Means for Solving the Problems]

In order to achieve the above object, the building panel of the present invention comprises:
As shown in the drawings corresponding to the examples, in a building panel in which a backing plate (2) is integrally attached to the back surface of a square face plate (1), both sides of each side of the backing plate (2) are provided. A corner side straight side part (3) having a corner part and a center part and having end faces flush with the side faces of the surface plate (1) corresponding to these parts, and this corner side straight side part (3).
