Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a joint structure of a panel useful for constructing a building, an outer wall of a building, or a roof with a dry panel.

[Conventional technology]

This type of building, for example, the outer wall of a warehouse as a panel that forms a joint structure of the wall with a sandwich panel or the like, a siding material in which a plastic foam is integrally interposed between a metal sheet having male and female connectors and kraft paper, A plastic foam is interposed between metal plates, and a concave / convex portion is formed on a side wall in the longitudinal direction, and a sandwich panel in which the concave / convex portion is inserted, or Japanese Utility Model Publication No. Sho 63-20761,
No. 2858, and Japanese Utility Model Publication No. 57-20741.

[Problems to be solved by the invention]

However, in the conventional metal siding material, a synthetic resin foam is integrally interposed between a surface material and a sheet-like material such as kraft paper, and has a male and female connection structure, and a structure in which only one end is fixed, The width of the decorative surface is about 400mm,
When the thickness is about 25 mm or more, there are disadvantages that the siding material is easily detached, the decorative surface becomes mountain-shaped, and it is difficult to insert the male and female connecting portions. Further, the sandwich panel has a disadvantage in that it lacks aesthetics due to its structure being beaten in the brain via bolts, and must be constructed with a crane or the like. Of course, ALC siding and ceramic siding materials were heavy, had limited decorative surface and thickness, were difficult to construct, and had weaknesses in freeze-thaw. Further,
Covers the joint by attaching the cap with the mounting bracket,
Although the fixture was prevented from being exposed to the exterior, the mounting of the cap required a mounting bracket, which was poor in workability and poor in heat insulation and waterproofness. In addition, there is a risk that the joint cover may be detached if the panel is not properly installed, which also has a disadvantage of poor heat insulation and waterproofness.

[Means for solving the problem]

In order to eliminate such disadvantages, the present invention comprises a metal plate for the front and back surfaces, and a core material integrally interposed between the two surfaces. A sandwich panel formed with wedge-shaped outwardly protruding engaging pieces for attaching and engaging a joint cover is fixed by a fixture by abutting and connecting both side end surfaces thereof, and the joint is fixed to the engaging portion in the joint part. An object of the present invention is to provide a joint structure of a panel formed by fitting a cover.

Is about t ₁ = 15 to 200 mm and t ₂ = 5 to 50 mm. The back material 11 is as shown in FIG. 4, and mainly covers the back surface of the core material 10 as shown in FIG. 2, and has functions of a reinforcing material, a waterproof material, a moisture-proof material, and a fire-proof material. , And serves as a separating member for preventing the core member 10 from directly contacting the skeleton α. As shown in FIG. 4, the shape of the back surface member 11 is a gutter shape formed by a side surface 12 having a longitudinal edge bent inward vertically and a concave portion 13 bent near the side surface 12. It is. The width W ₄ is the same as the W _2. It is preferable that the back material 11 is formed so as not to contact the front material 1 as shown in FIG. 2 and is formed so that the front material 1 and the back material 11 do not form a thermal bridge. As shown in FIG. 1, the joint cover B is formed on the joint part C between the panels A, covers the head of the fixing tool β used when fixing the panel A, and This is for improving waterproofness, anticorrosion, and the like. More specifically, joint cover B
As shown in FIG. 5, a decorative surface portion 14 having a horizontal surface and a locking portion 20 projecting from the back surface of the decorative surface portion 14 are formed. A decorative surface portion 14 consisting of a side wall decorative surface 16 bent downward at an obtuse angle,

And a locking portion 20 including a locking groove 19 formed. The side wall decorative surface 16 is provided on the engaging piece 7 of the joint C formed by the panels A and the engaging portion of the joint cover B.
This is formed to ensure that both ends of the decorative surface portion 14 are brought into contact with the projecting piece 4 of the panel A under elasticity when the panel 20 is inserted and mounted. The locking portion 20 is inserted into the engagement piece 7 of the panel A at the joint portion C as shown in FIG. It is for fixing to the part C.

FIG. 3 and FIG.
The width of the engaging piece 7 is l ₁ , the width of the locking groove 19 is l ₂ , the width of the inserting piece 5 is l ₃ , and the width of the opening of the engaging groove 9 is l 1.
l ₄ , the height from the projecting piece 4 to the engaging piece 7 is h ₁ , the height from the locking piece 18 to the tip of the side wall decorative surface 16 is h ₂ , the height of the inserting piece 5 is h ₃ , When the depth of the groove 9 and _{h 4, l 1 ≒ l 2} , l 3 ≒ l 4,
The relationship is h ₁ ≒ h ₂ and h ₃ ≒ h ₄ .

 Next, a construction example will be described.

Now, in order to construct a joint structure as shown in FIG.
A panel A as shown in FIG. 2 and a joint cover B as shown in FIG. 5 are used. A surface material 1 is used as the panel A, and a 0.5 mm thick color steel plate is used as the back material 11.
A raw material composed of polyisocyanurate foam is filled as a core material 10 between the front and back materials 1 and 11, reacted and foamed, then cured and integrated, and a joint cover B is made of the same material as the surface material 1. It is formed by roll forming. Therefore, fixed by fasteners β consisting screw bis insert piece 5 side of the panel A ₁ to skeleton alpha. Then panel A ₂
Protruding piece 4 by inserting the engaging groove 9 of the insert piece 5 in panel A ₁
Is fixed by a fixing tool β. After the panel A is fixed on the frame α in this manner, the locking groove 19 of the joint cover B is inserted into the engaging piece 7 and the locking piece 18 is locked and fixed to the engaging piece 7. C for fixing the fixing member β. Further, in order to form the entire wall, the above-described steps may be sequentially performed.

〔The invention's effect〕

As described above, according to the joint structure of the present invention, a wide panel having fixing portions formed at both ends is used, so that both sides of the decorative surface can be firmly fixed to the frame.
The nail head does not appear on the decorative surface of the panel and can be formed into a beautiful appearance. Since the panel is fixed on both sides, there is an advantage that the decorative surface does not have a mountain shape. Since an attachment is not required to attach the joint cover to the joint, the workability can be improved. Since the insertion piece and the engagement piece are formed by projecting the distal end of the protruding piece outward, the insertion piece and the engagement piece become a waterproof surface, and rainwater and the like do not reach the skeleton side.
Horizontal stretching is also possible. Because of the structure in which the ends of the panels are connected to each other by the insertion pieces and the locking grooves, there is no gap between the panels, and the panels have excellent earthquake resistance, waterproofness, and airtightness. Because the metal surface material and back material do not contact even at the joints,
Excellent fire resistance, heat resistance and dew condensation resistance due to prevention of thermal bridges.
There are features and effects such as.
