JPH07324445A - Engaging method for metal roof sheet for horizontal laying, and clip therefor - Google Patents

Abstract

PURPOSE:To improve efficiency in roofing work by a method wherein a ridge- side holding part of a roof sheet on the lower tier is held to a clip that is slidably fixed to a roof structural member, and the roof sheet on the lower tier is drawn toward the eaves side together with the clip and engaged with an eaves-side engaging part of a roof sheet on the upper tier. CONSTITUTION:After a clip 6 is fitted into a fixing metal fixture 5, the clip 6 and an eaves-side engaging part 3 of a roof sheet 1 on the upper tier are lifted up and a ridge-side holding part 14 of the roof sheet 15 on the lower tier is inserted from the eaves side and held with a holding piece 7 of the clip 6. As the engaging part 3 of the roof sheet 1 and the clip 6 are pushed down, the clip 6 is stuck fast to the surface of a rafter 4. As the roof sheet 15 on the lower tier is drawn toward the eaves side, the clip 6 is slid, with its slot fitted onto the fixing metal fixture 5, being held with the holding part 14 of the roof sheet 15 and is engaged, being brought into the engaging part 3 of the roof sheet 1. Therefore, efficiency in roofing work can be improved by laying the roof sheets 1 and 15 on the upper and the lower tiers together in the state of being engaged with each other, using the clips 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for engaging upper and lower rows of roofing boards in a method of lowering a roofing metal roofing board from the ridge side to the eaves side, and a suspension used in this method. .

[0002]

2. Description of the Related Art Conventional horizontal thatched metal roofing boards are roofed by a construction method in which long roofing boards are sequentially engaged from the eaves toward the ridge.

The upper and lower edges along the longitudinal direction of the long roof plate are bent to form a ridge-side engaging portion and an eaves-side engaging portion, and the ridge-side engaging portions of the lower row roofing plates are First, engage with the hangers that have the engaging pieces that engage the ridge-side locking parts, fix the hangers to the talcs arranged from the ridge side to the eaves side, and then use the roof plate of the upper row. The eaves-side engaging portion is sequentially raised so as to engage with the ridge-side engaging portion of the lower row roof plate.

[0004]

Since the present invention is a construction method in which a metal roof plate is roofed down from the ridge side to the eaves side, there is an upper row roof plate first, and this roof side engaging part , The ridge-side locking parts of the lower row roof plates must be engaged and fixed with a suspender, etc., but at the engaging position of the upper and lower row roof plates, the engaging parts of the upper and lower row roof plates Since the locking part overlaps with the locking part, the fixing position of the suspension that engages the lower row roof plate locking part gets into the back surface of the upper row roof plate. It is possible.
Further, even if the suspenders are fixed and the locking portions of the lower row roof plates can be engaged with the suspenders, then the engaging portions of the upper row roof plates are first fixed to the suspenders. Engagement with the engaging portion of the lower row roof plate is difficult because the engaging portion and the engaging portion of the roof plate are formed in a structure that does not easily slip off after the construction.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a lower row roof plate is engaged and fixed by a hanging member fixed to a roof plate structural material such as talc first, and the lower row roof plate is suspended. It is configured such that it can be pulled down to the eaves side, and at the same time as the pulling down, the engaging portion of the lower roof plate can enter and engage with the engaging portion of the upper roof plate.

For this purpose, the suspension is provided with a long hole so that the suspension can slide with respect to the stopper of the suspension.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a normal roofing metal roof plate 1 has a ridge-side locking portion 2 that is bent upward and is raised on one side of the roof plate 1 and the other side. An eaves side engaging portion 3 bent downward in an inverted U-shape is formed in the. The ridge-side engaging portion and the eaves-side engaging portion are engaged with the eave-side engaging portion and the ridge-side engaging portion of the next-row roof plate, respectively, to form a roof plate surface. Then, each roof plate is fixed to the roof structural member by locking the ridge-side locking portion with a suspender.

In the method of engaging the roof boards according to the present invention, first, the roof boards 1 in the upper row are first laid, and the roof board ridges in the upper row are further provided at the eaves side engaging portions of the roof boards (not shown) in the upper row. The side engaging portions are engaged and fixed with a hanging member, and the eaves side engaging portions 3 of the roof row 1 in the upper row are lowered in a free state. Then, inside the roof plate 1, a fixing metal fitting 5 for a suspender is already attached on the talc 4 of the roof structural material near the eaves side engaging portion 3.

In the production stage, if the fixing metal member 5 is fixed in advance at a predetermined position of the talc, the on-site work is easy. A suspension 6 having a long hole is fitted into the fixing metal fitting 5 so that the fixing metal fitting 5 is inserted into the long hole (FIG. 2). At this time, work is performed while raising the eaves side engaging portion 3 of the upper roof plate.

As shown in FIG. 6, the structure of the suspender 6 is an engaging piece 7 which has one end raised downward in a hook shape, and a base portion 8 is provided with an elongated hole 9 in the center thereof. The end of the elongated hole 9 on the side of the locking piece 7 is a large-diameter circular hole 11 through which the head 10 of the fixing bracket 5 of the suspension can be inserted. Further, in the fixing bracket 5, the head 10 such as a nut is screwed into the bolt 12, but is not completely screwed,
A gap 13 is provided between the head of the bolt 12 and the head 10 such as a nut, and this gap has a small diameter of the bolt shaft.

Therefore, after the suspenders 6 are once fitted to the fixing fittings 5, the suspenders 6 and the eaves side engaging portions 3 of the upper roof plates are lifted up, and the roof plate ridge side which is roofed in the lower row. The locking portion 14 is inserted from the eaves side and locked to the locking piece 7 of the suspension 6 (FIGS. 3 and 4). After that, when the eaves side engaging portion 3 and the suspension 6 of the upper roof plate are pushed down, the suspension 6 comes into close contact with the talc 4 surface, and the long hole 9 of the suspension 6 becomes the same as the small-diameter gap 13 of the fixing fitting 5. It becomes a face. Next, when the lower row roof plate 15 is pulled down toward the eaves, the suspension 6 slides while the elongated hole 9 is fitted to the fixing metal 5, and the ridge side locking portion of the lower row roof plate 15 is engaged. It slides while being locked by 14, and enters into the eaves side engaging portion 3 of the roof plate 1 in the upper row and engages with it (FIG. 5).

In the suspension 6, the long hole 9 having a diameter smaller than that of the large diameter circular hole 11 is prevented from falling off by the large-diameter head portion 10 of the fixing fitting 5, so that the roof plate is securely fixed to the talc.

[0013]

According to the present invention, since the above-mentioned suspension is used and the roof plates in the upper and lower rows are engaged and the roof is lowered, the conventional roof boards can be used as they are and the upper and lower rows can be easily used. It is possible to engage the roof plates of the above.

Further, if the fixing metal fittings for the suspension are fixed to a predetermined position of the talc at the production stage of the factory, it is advantageous because dangerous work at a high place on the site can be omitted.

As described above, the engaging method of the present invention has good workability, and since the hanging is only one step of punching for providing the long hole in the conventional product, the roofing which does not cost much is performed. Can be done.
