Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a building panel (hereinafter simply referred to as a panel) useful for forming an exterior wall in a building or a building. .

[Conventional technology]

Heretofore, as this type of panel, a metal thin plate having male and female connecting portions formed on both side edges by roll forming has been put on the market. In particular, the panel for horizontal stretching had a male / female connection structure with a drop-in structure, and the joint bottom was exposed to the outside.

[Problems to be Solved by the Invention] However, since the joint bottom itself of this type of panel functions as an insertion edge and is inferior in waterproofness, a concave or convex rib may be formed on the insertion edge of the joint bottom. Is being done.
However, simply forming the concave and convex ribs on the insertion edge cannot provide perfect waterproofness, and it is usual to implant a seal material in the connecting portion, which increases the cost and seals between the connecting portions. Dimensional differences were caused by the materials. Also,
When a wall is formed using a panel with a drop-in structure, if it is stored under a window or at the junction with the eaves sky using a substantially U-shaped cross-section, the gap will be reduced by the amount of the panel dropped There was a drawback that it became empty. Further, the joint width is different between panels in which the drop-in and hook-type connecting structures are formed in one panel.

[Means for solving the problem]

In order to eliminate such a drawback, the present invention provides a long building panel having male and female connecting portions on both side edges in the longitudinal direction of the plate material, wherein the male connecting portion has a horizontal flat decorative surface. A side wall with one edge bent below the decorative surface, a lower edge with the tip of the side wall bent outward, a rising piece with the lower edge tip bent upward, and a tip of the rising piece bent inward. Locking piece, a locking groove consisting of the locking piece and the lower edge, an engaging piece having a tip of the locking piece bent upward and the tip protruding outward, and the engaging piece and the locking piece. And a protrusion projecting downward from a lower end of the rising piece and having a tip bent outwardly. The female connecting part bends the other end edge of the decorative surface downward and the locking piece. , A side wall formed longer than the length from the engagement piece to the engagement piece, an upper surface in which the end of the side wall is bent inward, and a front end of the upper surface A lower surface bent downward and outward, a fitting groove formed from the lower surface to the upper surface and having a substantially U-shaped cross-section, and a fitting groove formed from the upper surface and the lower surface formed longer than the opening length of the locking groove; Is provided.

〔Example〕

Hereinafter, a panel according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing the panel A, wherein 1 is a base material, 6 is a male connecting portion, and 16 is a female connecting portion. The base material 1 is, for example, a thin metal plate such as a color steel plate, a fluorocarbon resin-coated steel plate, an aluminum plate, an aluminum alloy plate, a stainless steel plate, a copper plate, an aluminum-zinc alloy-plated steel plate, a zinc-nickel alloy-plated steel plate, a clad steel plate, and a sandwich steel plate. (Including flat plate, embossed plate) bent and formed, or metal material as shown in the figure,
It is formed by extruding a plastic material or porcelain. The decorative surface portion 2 includes a decorative surface 2a having a horizontal surface in the figure, side walls 3 and 4 having both ends of the decorative surface 2a bent downward, and a side wall 3.
Is formed of a lower surface 5 projecting outwardly in parallel with the decorative surface 2a. As shown in FIG. 2 (a), the male connecting portion 6 has a rising piece 7 protruding upward from the tip of the lower edge 5.
And a locking piece 8 in which the tip of the rising piece 7 is bent inward.
A locking groove 9 formed by the lower edge 5 and the locking piece 8; an engaging piece 10 having the tip of the locking piece 8 bent upward; and a locking portion 11 formed by the locking piece 8 and the engaging piece 10. An engaging groove 12, a hanging piece 13 projecting downward from the lower end of the rising piece 7, a projecting part 14 having the lower end of the hanging piece 13 bent outward, and a ridge formed at the tip of the projecting part 14.
It consists of 15. Female coupling member 16 and the second view (b)
As shown in the figure, the upper surface 17 in which the lower end of the side wall 4 is bent inward,
A fitting portion 18 having a substantially U-shaped cross section from the upper surface 17 to the decorative surface portion 2 and a lower surface 19 having the left end of the upper surface 17 bent outward.
And a fitting piece 20 composed of an upper face 17, a fitting piece 20 and a lower face 19, and a fitting groove 21. More specifically, when the lower surface 19 is inserted into the engagement groove 12 to form a wall, FIG.
As shown in FIG. 3, when the wall is formed by locking the fitting piece 20 in the locking groove 9, the work can be performed by the hooking type as shown in FIG. 3 (b). Two panels can be constructed by one panel A. In addition, when the installation is easy to drop down to the eaves and the last piece is hooked, the innermost part of the eaves and the corners of the wall are formed at the corners of the eaves and the wall. And the upper end of the panel A cut in the middle of the decorative surface portion 2 can be accommodated without forming a gap. Further, since the locking groove 9 and the engaging groove 12 and the lower surface 19 and the fitting piece 20 are formed at substantially the same position, as shown in FIGS. 3 (a) and 3 (b), the joint formed by the drop-in type. width W ₁ and hooking relationship joint width W ₂ formed by expression are those capable construction without made different W ₁ ≒ W _2. Therefore, the joint width. Further, the locking groove 9 functions as a connecting portion when the panel A is hooked and has a function of returning rain when rainwater or the like is blown up by wind.

Here, the dimensional relationship of each part of the panel A according to the present invention will be briefly described with reference to FIGS. 2 (a) and 2 (b).
Therefore, in the male connecting portion 6 , the length from the lower end of the side wall 3 to the locking portion 11 is l ₁ , the rising piece 7 from the tip of the locking portion 11, the tip of the engaging piece 10, and the end of the locking groove 9. Length to the back,

〔The invention's effect〕

As described above, according to the panel of the present invention, the drop-in type and the hook type can be performed by one panel.
The gap at the upper end of the wall can be eliminated, and the design, heat insulation,
A wall with improved waterproofness can be formed. The rain return function of the locking groove prevents rainwater or the like from entering the inside of the skeleton, thereby improving waterproofness. Since the engaging groove and the engaging groove of the male connecting portion and the fitting piece and the lower surface of the female connecting portion are formed at substantially the same position, the joint width is constant regardless of whether it is installed by dropping or hooking. . The male connecting part has a locking groove and an engaging groove, and the female connecting part has a fitting piece and a lower surface.The lower surface is in the engaging groove for the drop-in type and the locking groove for the hook type. By inserting the fitting pieces, it is possible to construct both the splicing type and the hook type. The formation of the hanging pieces can minimize the thermal bridge between the substrate and the skeleton. There are features and effects such as.
