Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to easily and easily install a folded sheet roofing material,
The present invention relates to a folding plate roof fixture that can be removed.

[0002]

2. Description of the Related Art A conventional folding plate roof fitting of this type is shown in FIG.
As shown in FIG. ₃ , the roof mounting tool b and the reinforcing angle c are attached to the side wall a ₂ of the tight frame a formed by bending the thin plate to form the trapezoidal protrusion a ₁ through the bolt-nut β. Is common.

[0003]

However, the above-mentioned fixture for a folded plate roof is made of H steel, C, which is a roof base material.
Since it is welded and fixed to a shaped steel material and the like, marking out and welding work is required, and it requires too much labor when installing and cannot be installed on rainy or windy days. It had the drawback of being affected by the weather. Furthermore, it is difficult to remove the fixture for a folded plate roof that has been welded and fixed once, and it is impossible to remove the fixture for a folded plate roof again and re-roof the roof.

[0004]

In order to eliminate such drawbacks, the present invention hooks the fitting grooves of two base metal fittings onto the roof base from above the tight frame and fixes them with bolts and nuts. By fixing the tight frame to the roof substrate, there is no need for marking and
It is not necessary to carry out dangerous welding work, and it is easy to remove the folding plate roof fixture after construction. Again, remove the folding plate roof fixture and use the existing roof substrate as it is. Then, the present invention proposes a fixture for a folded plate roof that enables the roof to be changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A folding plate roof fitting according to the present invention will be described in detail below with reference to the drawings. 1 and 2 (a),
(B) is a perspective view and a construction state explanatory view showing a typical folded plate roof fixture according to the present invention, in which a tight frame A, a base metal fitting B, a roof fitting C, a roof base α, and a bolt-nut. It consists of β.

More specifically, as shown in the figure, the tight frame A is a thin plate (flat bar) steel material, various steel plates, aluminum plates, copper plates, stainless steel plates, metal plates such as titanium plates, or reinforced FRP or the like. It is formed by bending (pressing, injection molding, etc.) a resin or the like, and has a horizontal flat bottom piece 1, a rising piece 2 in which one edge of the bottom piece 1 is bent upward, and a tip of the rising piece 2 is a bottom piece. 1 and a top piece 3 that is bent substantially parallel to each other, and is formed of a short body having a crank-shaped cross section.

The tight frame A is a base of a fixture for a folded plate roof on which a base metal fitting B and a roof fitting C described later are mounted, and improves the strength of the fixture for a folded plate roof. . As shown in FIGS. 2 (a) and 2 (b), the bottom piece 1 is a portion that abuts on a roof base α such as an H-shaped steel material, and is sandwiched between base metal fittings B and tight frame A.
Is a part that is attached and fixed to the roof base α.

Further, the rising piece 2 is a portion for fixing the roof mounting tool C for mounting the folded plate roof material using a bolt-nut β on the upper end thereof, and has a fixing hole 4. is there. Further, the upper piece 3 supports the folded plate roof material together with the roof mounting tool C, and functions as a holding material and a backup material. In addition, as shown in FIG. 1, it is also possible to form concave or convex ribs 5 for reinforcement on the tight frame A.

Further, the base metal fitting B is, as shown in FIG.
The jig is formed by molding the same material as the tight frame A by a similar processing method, and is a jig for attaching and fixing the tight frame A to the roof base α as shown in FIG. As shown in FIG. 2B, which is a sectional view taken along the line EE of FIG. 2A, the shape is such that the fixing piece 6 having a substantially vertical cross section and one end of the fixing piece 6 are bent at a substantially right angle. The fitting groove 7 is formed by folding back in a U shape and is formed in a piece shape. Further, a fixing hole 8 through which the bolt-nut β is inserted is formed and placed at a substantially central portion of the fixing piece 6.
In addition to the fixing hole 8 shown in FIG. 1, the fixing hole 8 may be a long hole for adjusting the unevenness and level. In addition, one base metal fitting B is attached to one edge of the bottom piece 1 of the tight frame A.
₁ is attached (fixed at the factory) beforehand by metal welding or separately with an adhesive (not shown) and fixed,
It is also possible to simplify the construction.

The base metal fitting B is composed of two base metal fittings B ₁ which can be welded and fixed to the bottom piece 1 of the tight frame A in advance and an independent metal base material B _2. . As shown in FIG. 2 (b), the base metal fitting B is a base metal fitting B ₁ which can be welded and fixed on the tight frame A by a lip α _{1 of an} H-shaped steel material which becomes a roof base α. Then, the fitting groove 7 is attached by hooking the fitting groove 7 on the other side, the fixing piece 6 of the other independent base metal fitting B ₂ is back-to-back, and the fitting groove 7 is provided on the other lip α ₂ of the H-shaped steel material. The fitting for the folded plate roof is fixed on the roof base α by fitting and fastening the bolts and nuts β through the fixing holes 8. In this way, by mounting the folding plate roof fixture on the roof base α, there is no need for troublesome and dangerous welding work, and since the bolts and nuts β are used for fastening, it is easy to remove the existing roof base α. The roof can be re-used by using as it is.

Further, the roof mounting tool C may be an existing one as shown in FIG. 1, and is generally a mounting tool C ₁ having a U-shaped clamping tongue 9 for clamping the male and female portions of a folded plate roof material. And the fixture C ₁
It is composed of two members of an L-shaped angle C ₂ fixed to the tight frame A by a bolt-nut β in parallel with.

What has been described above is only one embodiment of the folded-plate roof fitting according to the present invention, and each member constituting the folded-plate roof fitting can also be configured as follows. That is, FIG. 3 (a) shows an example in which the upper piece 3 of the tight frame A is cut out, FIG. 3 (b) shows an example in which the end of the rising piece 2 is bent in a U shape, and FIG. 4 (a) shows the rising piece 2 Fig.4 (b) shows two tight frames
It is an example of a fixture for a folded plate roof in which the two are back to back and the strength is improved.

FIGS. 5 to 7 show modified examples of the base metal fitting B, and FIGS. 5A and 5B show the fixing piece 6 to the fitting groove 7.
It is an example of the base metal fitting B in which the convex and concave reinforcing ribs 10 are formed to improve the strength and reduce the plate thickness to save the material cost. 6 and 7 are examples in which the cross-sectional shape of the base metal fitting B is modified according to the shape of the roof base α. That is, FIG. 6 shows a base metal fitting B which can be used when the roof base α is a C-shaped steel material. It is an example of a base metal fitting B capable of fixing the folded plate roof fixture to the roof base α by forming the piece 11 and hooking it to the lip α ₁ of the C-shaped steel material.

Further, FIG. 7 shows an example of a base metal fitting B which can be used when the roof base α has a rectangular cross section such as a square steel material (hollow square pipe) or a square wood (rafter). Groove 7
Is an example of a base metal fitting B capable of fixing the folding plate roof fixtures from both sides by fixing the height of the base to the height of the side surface of the roof base α to the roof base α.

[0015]

As described above, according to the folding plate roof mounting member of the present invention, the fitting grooves of the two base metal fittings are hooked on the roof base material from the bottom piece of the tight frame and fastened with bolts and nuts. However, since the tight frame is fixed to the roof base, it is not necessary to perform dangerous welding work, and the construction can be performed regardless of the weather. It is easy to remove the folded-plate roof fixture after construction, and it is possible to remove the folded-plate roof fixture again and use the existing roof substrate to re-roof the roof. Features such as
