Description

[Detailed Description of the Invention] The present invention relates to a construction panel in which a core material functioning as a heat insulating material, a fireproofing material, and a reinforcing material is filled between a concave molded body made of a thin metal plate or a synthetic resin plate and a sheet-like material. More specifically, a concave groove is formed in the lower part of the male connecting part of the construction panel, and caulking agent is planted at the base of the engaging tongue, which is formed by providing a step and raising the end of the female connecting part of the extension part. This invention relates to a construction panel with improved packing properties at joints.

In general, in architectural panels that have a male/female connection structure, the extension of the female connection part and the insertion edge of the male connection part are formed at an angle that allows elasticity to interact with each other, making installation and insertion easier. At this time, the insertion edge and the engagement groove are brought into strong contact with each other to strengthen the engagement force and prevent rainwater from entering. However, in the case of a construction panel having this structure, since the lower edge of the engagement groove and the insertion edge are in close contact with each other, there are drawbacks such as capillarity occurring at the joints and requiring skill in construction. In addition, some construction panels have ribs on the extension of the female connecting part to bring the insertion edge into contact with the engagement groove/extension at two places to improve packing performance. However, when constructing this construction panel, the nails are driven at a position lower than the ribs, so if the height of the ribs is made too high, the ribs will be damaged during nailing. Furthermore, since the contact for waterproofing and packing is between hard plates, there is a disadvantage in that the waterproofing and packing properties are poor.

In order to eliminate these drawbacks, the present invention provides a level difference between the tip of the extension of the female connector and the lower edge of the insertion groove, and caulking agent is implanted at the base of the raised engagement tongue. When inserted and inserted, the engaging tongues elastically abut against the back surface of the core material of adjacent architectural panels, and the engagement of the grooves, caulking agent, and engaging tongues strengthens the packing performance and engagement force. In addition, the present invention proposes a construction panel that can form a gap in which no capillary phenomenon occurs between the back surface of the insertion edge and the surface of the insertion groove at the joint portion.

EMBODIMENT OF THE INVENTION Below, one Example of the architectural panel based on this invention is described in detail using drawings. FIG. 1 is a perspective view showing an example of the above-mentioned architectural panel (hereinafter simply referred to as a panel), in which 1 is a main body with a rectangular decorative surface 2 and side walls 3 and 4 whose longitudinal edges are bent inward. It has a concave cross section. The material for the main body 1 is one of a thin metal plate, such as a surface-treated steel plate, a stainless steel plate, a copper plate, or a synthetic resin plate. Reference numeral 5 denotes a male type connecting portion, which includes a reinforcing piece 7 formed by bending the lower end of the side wall 3 outwardly into an insertion edge 6, the tip of which is bent inward into a seam shape, and following the same pattern, and a tip of the reinforcing piece 7. A groove 8 that is bent downward and then bent upward again to form a substantially concave cross section.
It was formed from. During construction, this groove 8 is engaged with an engaging tongue piece 12, which will be described later, and a caulking agent 13 implanted therein, thereby enhancing packing performance. Reference numeral 9 denotes a female connecting portion, which has an engaging groove 10 formed by bending the lower end of the side wall 4 inward and outward again to have an inverted U-shaped cross section;
an extension part 11 that protrudes outward from the lower edge 10a of the
The engaging tongue piece 1 is formed with a step from the middle of the extension part 11 to the tip than the lower edge 10a so as to have a rectangular cross section.
It was formed from 2. Also, the engaging tongue piece 12
is formed from side surfaces 12a and 12b, an upper surface 12c, and a stabilizing support piece 12d provided as required. 13 is a caulking agent, and the engaging tongue piece 12
It is planted at the base of the side surface 12a, and is made of a waterproof and elastic material such as synthetic rubber or synthetic resin. To explain further, as shown in FIG. 2, at the joint α when the panel is constructed, the engaging tongue piece 12 engages with the groove 8 and the caulking agent 13, and also contacts the core material 14 described below. The packing property, waterproof property, and engagement force are strengthened, and a sufficient gap β is formed between the reinforcing piece 7 and the lower edge 10a of the engagement groove 10 to prevent capillary phenomenon and prevent rainwater from penetrating the nail head. the engaging tongue piece 1
2, the tip part has a beautiful appearance without distortion. 14 is a core material that functions as a heat insulating material, a reinforcing material, a cushioning material, and a fire retardant material, such as hard polyurethane foam, isocyanurate foam, polystyrene foam, phenol foam, polyethylene foam, polyolefin foam, vinyl chloride foam, etc. polymer foam resin,
Or foams containing mineral fibers such as glass wool, rock wool, and asbestos, or lightweight aggregates such as perlite, shirasu balloons, and vermiculite, and fire retardants such as borax and sodium metaborate. It consists of seeds and is attached by self-adhesion or by means of an adhesive. 15 is a sheet-like material that covers the back surface of the core material 14. The material is, for example, a sheet-like material laminated with one or more of asphalt felt, terfelt, asbestos paper, kraft paper, aluminum foil, copper foil, synthetic resin film, nonwoven fabric, etc. . Here, to explain the dimensional relationship, h ₁ is the height from the surface of the extension part 11 to the upper surface 12c, h ₂ is the height from the surface of the decorative surface 2 to the surface of the extension part 11, and the height of the side wall 4 is h ₃ , insertion edge 6
W _{1 is the length from the tip of the groove to the groove 8, and the length of the engagement groove 10 is W 1} .
The width from the deepest part to the side surface 12a is W ₂ , and the engagement groove 1
The width from the innermost part of 0 to the side wall 4 is W ₃ , and the engaging tongue piece 1
If the width of 1 is W ₄ , then the relationship h ₁ ≦h ₂ −h ₃ W ₃ ≦W ₁ <W ₂ holds. Note that the upper surface 12 of the engaging tongue piece 12
The width _W4 of c is set depending on the purpose.

Next, an example of construction of a panel according to the present invention will be explained. Now, as shown in FIG. 2, the upper surface 12c of the engaging tongue piece 12 of the panel ○I is fixed to the body edge A via the nail B. Next, insert edge 6 of panel ○B into engagement groove 10, and fix 12c (not shown) of engagement tongue piece 12 at the other end to body edge A in the same manner as panel ○B.
Therefore, in order to form the wall, it is sufficient to repeat such operations one after another.

Therefore, a panel as shown in Figure 1 (h ₁ = 2.5 mm,
W ₄ = 8 mm) to form a joint α as shown in Figure 2, and a rib (height 1

The core material 11 is made of polyurethane foam with a density of 30 kg/m ³ , and the sheet material 15 is made of kraft paper laminated with aluminum foil. As a result, water leakage at the joint α using the panels of the present invention was at an average pressure of 160 kgf/ ^m2 , while that at the joint using conventional panels was 35 kgf/m2.
It was f/ ^m2 .

What has been described above is only one embodiment of the panel according to the present invention, and the engaging tongue piece 12 is configured so that the angle θ of the side surface 12a is an acute angle as shown in FIG. It is also possible to form a panel in which θ is formed at an obtuse angle and the core material 14 is formed as shown in the figure, or c
