Abstract

(57) [Summary] (Correction) [Purpose] When the roof is covered with a single letter, the protrusions of obstacles can be escaped, and the engaging parts can be engaged horizontally and vertically without the need for grasping. Enables roofing. [Structure] Engagement pieces formed on a week side of a substantially quadrangular plate member are inclined so that an upper engagement piece 11 and a lower engagement piece 12, and a side upper engagement piece 13 and a side lower engagement piece 14 are parallel to each other. Turn back to.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a single-character roofing material used for roofing.

[0002]

[Prior art]

 In the one-letter roofing material, the peripheral edges of a substantially rectangular plate member 50 are bent toward the front surface side and the back surface side to form engagement pieces 51, 52, 53, 54, and the engagement pieces are sequentially engaged. The roof surface is constructed by joining and joining. The respective engagement pieces 51, 52, 53, 54 are formed in parallel strips, and the engagement piece 53 that is bent to the front surface side and the engagement piece 54 that is bent to the back surface side when connecting in the lateral direction are formed. The width b of the upper engaging piece 51 that is bent to the front side in the ridge-side direction for bending in the same width a and a ′ and connecting in the vertical direction is the width b of the lower engaging piece 52 that is bent to the back side in the eaves side direction. It is generally made wider than the width b '(Fig. 5).

The reason why the bending widths b and b ′ are different between the upper side and the lower side is that the projection D (FIG. 8), which is an obstruction of the horizontal joint described below, is avoided in addition to the improvement of waterproofness. This is because. Therefore, regarding the engagement, as shown in Fig. 5, the preformed 50a is joined as shown in Fig. 6, and as shown in Fig. 7, the ridge side is bent to the front side and the eaves side is bent to the back side by grasping. Engaged in sequence and thatched the roof.

[0004]

[Problems to be solved by the device]

 In the prior art, the grasping work not only requires skill and labor, but also when the engaging pieces 53, 54 are folded back to the front surface side or the back surface side, four materials are overlapped, so that the materials are separated from each other. Or more than that, the protrusion D is formed (FIG. 8). When the protrusion D is bent to the back surface side, the width b of the engagement piece 51 bent on the ridge side is larger than the width b ′ of the engagement piece 52 bent to the back surface side. So I had to remove it.

[0005]

[Means for solving problems]

 The engaging pieces provided on the peripheral edges of the substantially quadrangular shape are made into an oblique shape that widens from one side end to the other side end, and the left and right sides and the upper and lower sides are formed without forming the protrusion D. It provides a roofing material that is easy to join and that does not shift the position of the roofing plate during construction and is easy to construct.

[0006]

[Constitution of device]

 The drawing shows one embodiment according to the present invention, and Fig. 1 shows a perspective view of a roofing material A for one letter.

A is a roofing material in which an end of a metal roofing plate such as a copper plate is bent and formed. The roofing material A has engaging pieces 11, 12, 13, and 14 which are respectively bent around a substantially rectangular plate material, and one side edge is folded back to the front side and the other side engaging piece 13 and the other side engaging piece 13 are folded. The lower engaging piece 14 whose side edge is folded back to the back side is provided, and the lower engaging piece 12 whose eaves side edge is folded back to the back side and the upper engaging piece whose ridge side edge is folded back to the front side A piece 11 is provided. The upper engaging piece 11 whose end on the ridge side is folded back to the front side is wider than the lower engaging piece 12 and is formed by bending.

Each of the engaging pieces 11, 12, 13, 14 is formed with a slight gap g at each of four corners at the time of folding back in order to facilitate watertightness and easy engagement. Is a narrow width of x1, x12, and the other side end is folded back with a wide width of x2, x22, and the engaging pieces 11, 12, 13, 14 have an oblique shape, respectively, and the engaging pieces 11, 12 and The engaging pieces 13 and 14 are parallel to each other, and the intersections of the edges 11a, 12a, 13a and 14a are substantially perpendicular to each other. Although not shown, instead of folding the engaging pieces 13 and 14 into an oblique shape, when the engaging pieces 13 and 14 are formed by cutting the left and right ends slightly obliquely in a plate state, one side end portion is formed. The x12 and the other side end x22 may have the same width and may be folded back.

[0009]

[Advantageous effects] The roofing material A formed as described above is constructed by engaging and engaging the engaging pieces 11, 12, 13, 14 with each other, but to connect them in the lateral direction parallel to the eaves The upper side engaging piece 13 and the lower side engaging piece 14 of the roofing material A are engaged and joined (Fig. 2). At this time, since the upper engagement piece is formed in an oblique shape, the width of the upper engagement piece 11 of one roof material A, which is the width X2, is smaller than the width of the upper engagement piece of the other roof material A. It is engaged so that a part of X1 is fitted.

In the roofing material A for single-letter roofs connected and constructed as described above, the respective engaging pieces 11, 12, 13, 14 are obliquely formed (edges 11a, 12a, 13a, 14a are substantially perpendicular to each other). By this, the edge portions 11a of the upper engaging pieces 11 are parallel to the eaves, and the edge portions 11a when they are sequentially connected are almost straight (FIG. 3).

After installing in the first row (front of the eaves) in a horizontal row, the roof is raised in the order of 2, 3, ... At this time, since the lower engaging piece 12 of the next-stage roof material A is engaged with the straight edge portion 11a of the engaging portion 11 and the roof is raised, the roof material A is parallel to the eaves of the roof. It is not necessary to install it while manually processing the roofing material (bending by engaging the engaging part, cutting off the protruding part D) as in the prior art, but if the engaging parts are simply hooked sequentially Very well, it has various effects such as an elegantly raised appearance after construction and is extremely effective.
