Description

  The present invention relates to a roof repair metal fitting for attaching a new roof material on a corrugated roof material such as an aging factory.

  After the war, as a roof material for buildings such as factories, inexpensive, fire-resistant, water-resistant, and durable slate mixed with asbestos and cement has been used favorably, but rain leaks with their aging. It has become necessary to perform repairs. Since repairs by replacing existing slate require that large-scale measures be taken, such as stopping factory operations, new roofing materials such as corrugated sheets or folded plates are usually pasted on existing slate. It is common to make repairs.

  As is well known, the slate contains asbestos that has a negative effect on the human body, and in order to provide a foundation for a new roofing material, the repair of drilling the existing slate with a drill or the like will cause dust to fall into the factory. This is not preferable. Therefore, for attaching a new roofing material, for example, a plurality of support fittings disposed on the outer surface of an existing slate plate and an exterior base material having a support surface for supporting the new roofing material. The support bracket is configured to have a pair of leg portions that are arranged in a trough portion on both sides of the existing slate plate and a tip portion of an existing bolt that protrudes from the outer surface of the existing slate plate. The exterior material replacement treatment includes an insertion locking portion that is inserted and locked in a gap between the tightening nut and the nut washer that are screwed together, and an exterior base material support surface for supporting the exterior base material. Tools are often used (Patent Document 1).

However, the above-mentioned exterior material replacement jig temporarily loosens the tightening nut that is screwed into the existing bolt protruding from the slate plate, and supports the support metal fitting in the gap formed between the tightening nut and the nut washer. Since the insertion lock part is inserted and the nut is tightened again to fix the support bracket, it is not easy to loosen or tighten the tightening nut from the rusted bolt due to deterioration over time. There was a problem that construction required a lot of time and labor, such as crushing the bolts or breaking the bolts themselves.

Further, the tip is bent upward by approximately 15 °.

  On the other hand, the bolt tension member 3 shown in FIG. 3 has a substantially side view attached to the pressed portion 2c so as to cover the pressed portion 2c of the support 2 described above, as shown in FIGS. The upper and lower surfaces are respectively formed with insertion holes 3a and 3b through which the roofing material fixing bolt 6 is inserted, and the inclined surface is formed with a screw hole 3c into which the pressing tool 4 is screwed. . The insertion holes 3a and 3b of the bolt tensioning member 3 have the same diameter as the bolt insertion hole 2d of the purlin support surface 2a and are attached to the pressed portion 2c of the support 2 as shown in FIG. A gap is formed between the pressed portion 2c and the pressed surface 20c.

  The pressing tool 4 that is screwed into the screw hole 3c of the bolt tensioning member 3 and presses the pressed portion 2c of the supporting tool 2 from the side is a general + screw, and thus a general screw is used. By doing so, it can be easily and quickly tightened with the electric tool, and the workability is very good.

  The dimensions of the roof repair fitting 1 composed of the support 2, the bolt tensioning member 3, and the pressing tool 4 are not particularly limited, but the existing corrugated roofing material 5 that has been widely used as a roofing material for buildings. According to the size, a front and rear length of about 100 mm, a left and right width of about 150 mm, a height of about 60 mm, and a width of the support leg 2b of about 18 to 20 mm are preferably used.

  The roof repair metal fitting 1 having the above-described configuration is attached to the existing corrugated roofing material 5 as follows.

  That is, as shown in FIG. 4, first, the bolt tension member 3 is attached so as to cover the pressed portion 2 c of the support 2. And as shown in FIG. 5, the roof material fixing bolt 6 of the existing corrugated roof material 5 is provided with a bolt insertion hole 2d formed on the purlin support surface 2a of the support 2 and an insertion hole 3a of the bolt tension member 3. As shown in FIG. 9, the lower end surfaces of the support leg portions 2 b and 2 b of the support tool 2 are placed on the valley portions 5 b and 5 b of the existing corrugated roof material 5.

  After mounting the roof repair metal fitting 1 on the existing corrugated roof material 5 as described above, the pressing tool 4 (screw) is tightened into the screw hole 3c of the bolt tension member 3 with an electric tool. When the pressing tool 4 is tightened, the tip part thereof comes into contact with the pressed surface 20c of the pressed part 2c, and when the screw 4 is further tightened, as shown in FIGS. Begins to press the pressed portion 2c in the direction of the arrow P1. When the pressed portion 2c is thus pressed in the direction of the arrow P1 by the pressing tool 4, a force in the direction of the arrow P1 acts on the support tool 2, and the bolt tension member 3 is opposite to the arrow P1 (pressing direction). Since the force in the direction (arrow P2 direction) acts, the support 2 starts to move in the direction of arrow P1, and simultaneously, the bolt tension member 3 starts to move in the direction of arrow P2.

  As described above, when the support 2 and the bolt tension member 3 move in the directions of arrows P1 and P2, respectively, the inner peripheral surface of the bolt insertion hole 2d of the purlin support surface 2a and the insertion holes 3a and 3b of the bolt tension member 3 Since the peripheral surface abuts against the roof material fixing bolt 6, the roof material fixing bolt 6 is firmly held at the three points of the inner peripheral surface of the bolt insertion hole 2 d and the inner peripheral surfaces of the insertion holes 3 a and 3 b.

After the material fixing bolt 6 is inserted into the bolt insertion hole 2d formed on the purlin support surface 2a of the support 2 and the insertion holes 3a and 3b of the bolt tensioning member 3, the pressing tool 5 is pressed against the support 2 When the portion 2c is pressed from the side, the support tool 2 moves in the pressing direction, while the bolt tension member 3 moves in the direction opposite to the pressing direction. Therefore, the roofing material fixing bolt 6 is inserted into the bolt of the support tool 2. The hole 2d is firmly held between the inner peripheral surface and the inner peripheral surfaces of the insertion holes 3a and 3b of the bolt tension member 3. Moreover, since the pressed portion 2c of the support 2 is provided so as to protrude approximately 45 ° obliquely upward from the purlin support surface 2, the purlin support surface 2a of the support 2 and the existing corrugated roof material 5 are provided. Even when there is almost no gap with the mountain portion 5a, it is possible to work in a standing posture and the workability is very good. Further, even if the bolt tension member 3 is attached to the pressed portion 2c, it does not protrude because it fits in the notch portion 2e, and the bolt insertion hole 2d is formed near the center portion of the base material support surface 2a. There is a remarkable effect that the stability when 1 is attached to the existing corrugated roofing material 5 is excellent.
