JPH1088748A - Connecting construction of metallic roof plate - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide the connecting construction of roof plates which can deal with expansion/contraction of a roof plate due to change of atmospheric temperature, and prevent rainwater, dust, and the like from infiltrating. SOLUTION: In this connecting construction of metallic roof plates, the right and left longitudinal standing seam parts 12 of a roof plate 11 formed out of metallic plate such as copper plate or stainless steel plate are respectively bent both sides in the opposite direction so that the end edges are contacted with the surface and back faces of the roof plate 11, and further the extreme end edges are bent in the reverse direction so as to rise, and hence rising parts 18 are formed. When the adjoining roof plates 11 are joined together, it is constituted so that the bent parts are respectively stuck fast to the surface and back faces of the mutual roof plates.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure for a metal shingle, and more particularly to a connection structure for a shingle used in a single-roofing method.

[0002]

2. Description of the Related Art A metal roofing plate used in a single-roofing construction method is formed in a rectangular shape having left and right vertical gouges, upper goby, and lower goby which are bent in opposite directions. The roof shingles are connected to each other by cutting and separating the roof shingles for each dimension in the unfolded state from a long metal plate such as a long copper plate having a predetermined dimension in advance. Then, firstly, the left and right vertical goby of the roof plate in the unfolded state are formed by bending in the opposite directions, respectively, and then the upper goby and the lower goby are bent in the opposite directions, leaving both left and right ends. After forming, or bending the vertical goby in the opposite direction, respectively, connecting the roof plates to each other in the left-right direction by engaging the vertical goby, A method is employed in which both the left and right end portions are bent and formed in opposite directions.

[0003] The roof shingles formed as described above are connected in a straight line by connecting the roof shingles from the eaves to each other in the left-right direction by engaging a vertical goby at the construction site, and then connecting the roof shingles up and down. The edges are bent in the opposite directions to form the remaining upper goby and lower goby, respectively, and the roof is sequentially raised upward on the ridge side.

[0004]

However, the conventional vertical goby is formed by temporarily bending the left and right ends 2, 3 of the roof slabs 1, 1 as shown in FIGS. After the vertical fins 4 and 5 of the adjacent shingles 1 and 1 are engaged with each other, the fins are further bent so as to connect the shingles 1 and 1 with each other. May occur. Therefore, it is possible to cope with the expansion and contraction of the roof slab due to a change in temperature, but there is a problem that rainwater, dust and the like intrude from the gap and accumulate over the years, causing a leak of rain.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and is capable of coping with expansion and contraction of a roof slab due to a change in temperature, and in which rainwater, dust, and the like enter. The present invention provides a connection structure for a roof shingle that does not need to be connected, and the left and right vertical goby portions of a roof shingle formed of a metal plate such as a copper plate or a stainless steel plate have their edges contacting the front and back surfaces of the roof shingle. When the front roof is bent in the opposite direction, and the leading edge is bent in the opposite direction to form a rising portion, and the adjacent roof plates are joined, the bent portion is formed. Are provided so as to be in close contact with the front and back surfaces of the roof shingles, respectively.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. Reference numerals 11, 11,... Denote roof plates made of a copper plate or the like. On the left and right ends of the roof plate 11, vertical gouges 12, 13 are formed by being bent in opposite directions. An upper gob 14 is formed at the upper end of the roof slab 11, and a lower gob 15 is formed at the lower end thereof by being bent in opposite directions. Are connected to each other by engaging the vertical gouges 12 and 13 with each other, and an upper gob 14 and a lower gob 15 located at both ends thereof.
Are developed 14a, 14b, 15a, 15b.

The vertical goby 12, 13 is bent so that its edge contacts the surface 16 or the back surface 17 of the shingle 11, and the leading edge thereof is bent in the opposite direction. Raised portions 18 and 19 are formed.

[0008]

As described above, according to the present invention, the right and left vertical goby portions of a roof plate formed of a metal plate such as a copper plate or a stainless steel plate are brought into contact with the front and back surfaces of the roof plate. Bends in the opposite direction to the front and back, respectively, and bends in the opposite direction to further raise the leading edge to form a rising portion, and when the adjacent roof plates are joined, the bent portion is Since each of the roof plates is in close contact with the front and back surfaces of the shingles, no gap is formed in the connection portion, so that intrusion of rainwater, dust, or the like, which causes rain leakage, can be prevented. Further, according to the present invention, since the rising portion is formed at the leading edge of the vertical goby, it serves as a guide when connecting the roof shingles, so that the connecting operation can be performed extremely easily. Further, according to the present invention,
Since the connection is simply made to engage, the invention has an effect that it can sufficiently cope with expansion and contraction of the roof shingle due to a change in temperature, and is a practically useful invention.
