Description

  The present invention relates to a slate roof fall prevention repair structure. More specifically, the slate can be prevented from falling during disasters such as aging degradation, earthquakes, storms, and construction, and safety nets. The present invention relates to a fall prevention repair structure for a slate roof that can safely attach a roofing material to an appropriate posture without need.

  2. Description of the Related Art Conventionally, as existing roofs of factories and the like, generally constructed by attaching slate to the upper surfaces of a plurality of long materials. In this existing roof refurbishment method, it is common to first lay a safety net on the upper surface of the slate to prevent the operator from falling, and then attach the repair roof material to the upper surface of the slate with mounting bolts. Has been done. Thus, the roof material can be attached from the top of the existing roof, and the repair can be performed while the facilities in the existing roof are operated.

  However, in the above repair method, the slate and the roofing material are fixed only by hook bolts, so part of the slate is damaged during disasters such as aging degradation, earthquakes, storms, etc. and during construction. The debris may fall. Further, the safety net is usually laid by being hooked on a hook bolt. However, depending on the degree of the hook, there is a possibility that a place where the roof material is not well accommodated and cannot be attached in a correct posture.

  In addition, as a conventional slate roof refurbishment structure, a corrugated slate attached to the upper surface of a plurality of long materials with hook bolts, a hard urethane foam cut-out body bonded to the upper surface of the corrugated slate, and this hard urethane foam cut-out What is provided with the roofing material attached to the upper surface of the body is known (for example, refer patent document 1). However, in the said patent document 1, it aims at improving the heat insulation effect by providing a hard urethane foam cut-out body between a slate and a roof material, and it is not aimed at suppressing the fall of a slate. . In particular, in Patent Document 1 described above, it is necessary to form the bottom surface side of the rigid urethane foam cut-out body into a corrugated shape in accordance with the shape of the existing corrugated slate. There is a possibility that the adhesiveness between the urethane foam cut-out body and the corrugated slate is lowered, and the slate is dropped.

Further, the nut portion 8 screwed into the upper end screw portion 7 a of the hook bolt 7 is locked to the upper surface of the slate 3. Therefore, the long material 2 and the slate 3 are integrally fixed by the hook bolt 7. In addition, a lower end screw portion 9 b of a mounting bolt 9 that penetrates the roof material 5 and the slate 3 is screwed to the long material 2. The head 9 a of the mounting bolt 9 is locked to the upper surface of the roof material 5. Accordingly, the long material 2 and the roof material 5 are integrally fixed by the mounting bolts 9, and a part of the lower surface side of the roof material 5 is pressed against the upper surface of the elastic layer 4 (see FIG. 2).
In the first embodiment, the distance d1 between the axis of the mounting bolt 9 and the axis of the hook bolt 7 is set to about 30 mm (see FIG. 3). The hook bolts 7 are arranged at a predetermined pitch interval (for example, an interval of about 900 mm) along the long direction of the long material 2 and the direction orthogonal to the long direction.

(2) Construction Method of Slate Roof Drop Prevention Repair Structure Next, a construction method of the slate roof fall prevention repair structure 1 having the above configuration will be described.
First, as shown in FIG. 4, in the existing roof in which the slate 3 is attached to the upper surface of the plurality of long members 2 with the hook bolt 7, the upper end threaded portion 7 a of the hook bolt 7 protruding upward from the upper surface of the slate 3 is provided. Disconnect. Next, as shown in FIG. 5, after spraying an adhesive (precoat agent) on the upper surface of the slate 3, a fast-drying paint made of a urethane resin (for example, a paint that dries within a few seconds to a few tens of seconds) is sprayed. The corrugated elastic layer 4 is applied and formed on the upper surface of the slate 3. Next, as shown in FIG. 6, the roofing material 5 is placed on the upper surface of the elastic layer 4, and the roofing material 5 is fixed to the long material 2 with the mounting bolts 9 penetrating the slate 3, so 1 will be obtained.
