Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stacking surface structure used for a roof surface or a wall surface of a building or a structure.

[Prior Art] Conventionally, a roof tile method using colored tin as a roof made of metal has been known, but this has a drawback that the roof has a monotonous appearance. On the other hand, it is known that an asbestos slate is used for stacking as a material having an appearance grace, but it has a drawback that it is easily cracked and causes rain leakage. Therefore, as a face material made of metal, Japanese Patent Publication No. 50-18293 discloses that a wedge-shaped side surface is provided on one side of the shingles and a wedge-shaped groove is provided on the other side, and the side portions of the left and right shingles are formed into the wedge shape. There has been proposed a metal shingle plate which is connected by engaging a side surface with a wedge-shaped groove, and which connects and holds a holding slip and a connecting slip by engaging and disconnecting the shingle plate.

[Problems to be Solved by the Invention] In the metal shingle plate, the left and right engaging portions formed by the wedge-shaped side surface and the wedge-shaped groove are exposed, and the engaging portions have a wedge shape that shrinks upward. Therefore, there is a risk that rainwater may wrap around to the back surface of the face material at the upper engagement location.
Further, rainwater flowing down from the upper shingles to the lower shingles may enter the upper and lower engaging portions composed of the holding slip and the connecting slip, and thus the waterproofness is poor.

Therefore, an object of the present invention is to provide a stacking surface structure that is aesthetically pleasing and has excellent strength, and that can prevent rain leakage from occurring.

[Means for Solving the Problems] The present invention forms a metal lapping surface material integrally having a lower trapezoidal portion and an upper rectangular portion, and the left and right sides of the trapezoidal portion are formed. The lower peripheral edge is formed by bending the left and right diagonally downward wall surfaces and the lower inclined wall surface, and a flat plate-shaped heat insulating material having a substantially constant thickness is provided on the back surface of the stacking surface material, and the rectangular shape of the stacking surface material is rectangular. The left and right side wall surfaces corresponding to the thickness of the heat insulating material are provided in the shape portion, and one side wall surface is bent to the front surface side to provide an engaging portion, and the side portions of the stacking surface material arranged in the left and right are described above. The horizontal portion is provided at the lower edge of the rectangular portion that is not continuous with the trapezoidal portion by connecting the engaging portion with the other side wall surface, and the horizontal portion is provided. And the engaging portion is bent along the back surface of the rectangular portion above the horizontal portion, and A lower side wall surface formed by bending the front end side to the back surface side of the heat insulating material is provided continuously to the upper end portion of the stop portion, and the lower surface of the lower side wall surface on the front end side is a rectangle of the lower stacking surface material. The upper surface of the lapped roofing material is abutted against the surface of the ridge-shaped portion, and the engagement portion of the lower lapped surface material is covered with the trapezoidal portion of the upper lapped surface material so that the lapped surface material is stacked vertically. In addition, the peripheral side wall surface formed by bending the lower edge of the lower inclined wall surface of the upper laying-up surface material on the back side is engaged with the locking portion of the lower laying-up surface material. is there.
