Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to architectural panels (hereinafter simply referred to as panels) useful for constructing the outer and inner walls of buildings and structures. More specifically, even if the decorative surface width and panel thickness are increased, the panel has a male and female mating structure that will not peel off from the wall base, and that will not expose fixing devices such as screws and screws to the outside. It is.

[Conventional technology]

Conventionally, as shown in FIG. 6, this type of panel has been constructed by connecting panel a, which has a real structure on the back side, with a male-female mating structure, and fixing the end of panel a1 to the wall base α. A fixing device using a tool β has been devised.

[Problem to be solved by the invention]

However, a gap γ is formed between panels al and 82 by the head of the fixture β, and rainwater etc. blown up from the joint part is transmitted to the wall base α side through this large gap γ, and the wall base α is It had the disadvantage of corrosion. In addition, since the fixture β is formed near the joint, rainwater, etc. will directly reach the head of the fixture β and the fixing hole drilled in the panel a1 by the fixture β. There were drawbacks such as rusting of β and infiltration of rainwater from the fixing holes into the wall base α.

Furthermore, the fixture β was visible from the outside through the gap between the joints, resulting in a greatly inferior aesthetic appearance. In addition, the end of the back material on the fixed part side is fixed by the fixing tool β,
The end of the backing material on the lower end side is only fixed by the insertion edge C of the facing material, so if external force is applied due to an earthquake, wind pressure, fire, etc., there will be a difference between one end of the facing material and one end of the backing material. It was in a state where it was held down only by the strength of the joint edge C, which had the disadvantage of lacking connecting force.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention fixes the panel at one end, and also fixes from the surface side of the surface material by covering the fixing groove of the male connector with the upper surface of the female connector. This covers the fixtures, and the drop-in structure improves workability.Furthermore, the ends of the front and back materials that are not fixed by the fixtures can be used to cover the front and back materials that are fixed by the fixtures, respectively. To provide a panel that is fixed by the edges and is securely fixed to a wall base.

Next, a construction example will be briefly explained. Assume that panel A as shown in FIG. 1 is used and construction is performed as shown in FIG. 4. In addition, for panel A, a 0.5 m thick color steel plate was used as the surface material and the back surface material H, and as the core material 26, a raw material of phenol foam mixed with pearlite particles was discharged, reacted and foamed, and then It is cured and integrated into one. Therefore, the nth panel A is placed on the steel frame base, or the wall base α consisting of main columns, studs, waterproof sheets, etc.
1 fixing groove 10 is fixed via a fixing tool β such as a screw. Next, the fitting groove 15 for the female connection part of the n+1st panel A2 is inserted into the insertion edge 7 of the panel A1, and the engaging piece 24 is inserted into the engaging groove 20, as shown in FIG. This forms horizontal joints. Further, in order to form the entire wall body, it is sufficient to carry out the above-described process from the base to the girder, and 29 is a backing material, caulking material, etc. In addition, it is necessary to use a starter (not shown) for the base, caulking material, and accessories for parts (not shown) such as exit and entry corners, around windows, and vertical joints.

[Other Embodiments] What has been described above is only one embodiment of the panel A according to the present invention, which can be formed into shapes as shown in FIGS. 5(a) to 5(0).

[Effects of the Invention] As explained above, according to the panel according to the present invention, ■ fixing to the wall base is done by fixing the part of one edge of the surface material where the core material and back material are present in the lower layer; It is securely fixed to the wall base and will not peel off. ■ Large panels can be securely fixed to the wall base without exposing nails, bolts, etc. to the outside. ■The upper edge is recessed in the longitudinal direction to form a fixing groove that is wider and taller than the head of the fixing tool, so the fixing tool does not protrude beyond the upper edge or the joint base. , it is possible to improve the waterproofness, airtightness, and workability of the connection part. ■Since the length of the top surface is longer than the position of the fixing groove, the fixing tool will not be exposed to the outside. ■Even if there is a slight error in the joint width, the fixture will not be visible from the outside. ■The engaging pieces and grooves formed on the surface material prevent flames from fires, heat, and rainwater caused by wind and rain from penetrating into the wall base. ■The reinforcing piece formed on the male connection part side of the surface material is interposed within the core material, ensuring integration with the core material and improving the strength of the insertion edge against external forces. . ■If the reinforcing piece is formed to the point where it is fixed by the fixture, the strength of the insertion edge will be further improved. ■If the structure is such that the surface material and the back material do not come into contact even at the joints, thermal bridges are prevented and fire resistance, heat insulation, and condensation resistance are improved. [Phase] Since both ends of the backing material are fixed to the wall base, the wall becomes strong against external forces such as earthquakes and wind pressure. ■Depending on the shape of the facing material, the outer wall can be constructed with the backing material on the front side. ■The panel has improved waterproofness, airtightness, earthquake resistance, heat insulation, fireproofing, soundproofing, and workability. It has the following characteristics and effects.
