Description

  According to the present invention, the lower gob provided on one of the width end portions of the roof plate material main body is fitted to the upper gob of the roof plate material separately disposed adjacently, while the lower end of the width of the roof plate material main body is provided. In order to fix the roof plate material to the roof base material for the fitting roof plate material that connects the roof materials to each other by fitting the upper goby to the lower gob of another roof plate material that is separately disposed adjacently And a fixing jig used for the method.

  A fitting type roofing board material having a lower goby on one of the width end parts of the roofing board main body and an upper goby on the other side of the width end part of the roofing board main body is a roof board material separately arranged adjacent to the upper goby. It is possible to connect roofing materials by fitting them to the lower goby, and by fitting the lower goze to the upper goby of the roofing plate material that is separately arranged adjacent to each other. Often used for repair work of tiled rod roofs that are joined together.

  Each of the above-mentioned lower goby and upper goby has a mountain-shaped cross-sectional shape that forms a recess open toward the lower side (underlying material side). After being fitted to each other, locking jaws projecting in the opposite direction toward the outside are formed at opposite positions of the side walls so that the fitted state is not easily released. Here, the upper goby and the lower goby are fitted with each other by positioning the upper goby on the top of the lower goze and pressing the upper goze toward the lower goze so as to be elastically deformed, and by the spring back force of the upper goby. This is done by positioning the lower goby inside the upper goby.

  On the other hand, the roof plate material having such a structure is usually fixed to the base material by connecting the flange formed on the lower edge of the lower goby and the base material of the roof using a set screw. is there. By the way, in the case where the rigidity in the width direction of the roof plate material is increased and the resistance force against the negative pressure (pressure for peeling the roof plate material from the roof) acting during a storm is improved, it can be seen in, for example, Patent Document 1. The top of the lower goby is provided with a recess (concave) that houses the head of the set screw, and the bottom wall of this recess and the roof base material directly below this bottom wall are directly connected. Where the screws are connected to each other by means of set screws (new roof with a flat base material for the roof, etc.), in this case, there are problems as described below.

Registered Utility Model No. 3014906

  In other words, the set screw that connects the bottom wall of the lower goby and the base material located directly below it is screwed into the base material from the bottom wall side using a high-speed rotating electric tool such as an impact driver. However, since the bottom wall portion is not supported at all, the bottom wall portion is pushed toward the base material side of the roof as the screwing amount of the fixing screw increases, so that the screwing of the fixing screw is stopped halfway. Therefore, it is necessary to make the screwed height of the bottom wall constant.

  However, the adjustment of the screwing height of the bottom wall portion is carried out with a scale amount, which causes the work efficiency of the tightening operation of the set screw to be remarkably lowered. In addition, if the accuracy is poor, tightening of the waterproof packing, etc., placed between the bottom surface of the head and the bottom wall of the set screw is insufficient, and the effect cannot be fully exerted. If the screw is excessively screwed in, the lower goby will be elastically deformed greatly, so that the overhanging width of the locking jaw provided on the opposite side of the side wall will be excessive, and it will fit into the upper goby of the adjacent roof plate. It may be difficult to join.

  The object of the present invention is to fix the roof plate material under efficient work without causing the above-mentioned problems that occur when the bottom wall portion of the lower goby and the base material of the roof are connected with a set screw. A method that can be used, a fixing structure thereof, and a fixing jig used in the method are proposed.

  The present invention includes a lower goby that fits the upper goby of the adjacent roof plate material and connects the roof plate materials together, and is open upward at the top of the lower goze, and from the eaves side of the roof to the ridge side. In a method for fixing a mating type roofing board material in which a bottom wall portion of the recess and a base of a roof located immediately below the roofing board material are formed via a set screw. A screw holding portion for holding the set screw is installed on the bottom wall portion of the recess, and the lower gob is pressed toward the base material of the roof by the screw holding portion to be slightly elastically deformed. The screw holding part is screwed in with the screw holding part as the starting point while the deformation state is maintained, and the screw holding part is removed and the lower goby is restored after the screwing of the fixing screw is finished. It is a method for fixing mating roofing boards.

  In the method configured as described above, it is preferable to dispose a cushion material between the head of the set screw and the screw holding portion.

  In addition, the present invention includes a lower goby that fits the upper goby of the adjacent roof plate material and connects the roof plate materials together, and is opened upward at the top of the lower goze and is constructed from the roof eave side. For a roofing board material formed with a recess extending toward the side, a fitting-type roofing board material that connects a bottom wall portion of the recess and a base material of a roof located directly below the bottom wall part via a fastening screw. It is a fixing structure, and a cushioning material is provided immediately below the head of the set screw, and after the screwing of the set screw is finished, the cushion material is fixed to the bottom wall portion of the recess by restoring the lower goby. It is a fixing structure of the fitting type roofing board material characterized by being pinched | interposed between each other.

Further, the present invention is a fitting jig for fixing a roofing roof material used in the above method, and a pair of legs that can stand on the surface of the roofing sheet and the roof base material by sandwiching the lower sheet on both sides. And a connecting member connected to each upper end portion of the pair of legs, and with the connecting member, the lower goby is pressed toward the base of the roof in a standing posture of the legs, and is elastically deformed slightly. A fitting jig for fixing a fitting roof plate material, wherein a screw holding portion is provided to maintain a constant distance from the bottom wall portion to the roof base material and to removably hold a set screw. It is.

  In the fitting roof plate fixing jig having the above-described configuration, a pair of leg portions are held rotatably via a hinge on a leg main body directly connected to a connecting member and a terminal portion of the leg main body. Preferably, the leg main body is provided with a stopper that is slidably held along the leg main body and presses the tip portion against the grounding piece to support the grounding piece so as not to rotate.

  According to the fixing method of the roof plate material of the present invention, the distance from the bottom wall portion to the roof base material is maintained constant by the screw holding portion, so that the head of the fixing screw is attached when the fixing screw is screwed. When the screw holding portion is reached, the set screw is no longer screwed in, and the screwing height of the bottom wall portion is always kept constant. In addition, after the screw fixing part has been screwed in and the screw holding part has been removed, the lower goby is restored to its initial shape, so that a gap is created between the head of the set screw and the bottom wall of the lower goby. In the case where the cushion material is disposed between the head and the bottom wall portion of the set screw, the allowance for the cushion material can be secured.

  According to the method for fixing a roof plate material of the present invention, a cushioning material (an elastic member such as rubber, resin, or asphalt) is disposed between the head of the set screw and the screw holding portion, so that waterproofing prevents intrusion of rainwater. It can be made to function as packing which prevents generation of packing or wrinkles.

  Further, according to the fixing structure of the fitting type roofing sheet material of the present invention, a cushion material is provided immediately below the head of the set screw, and after the screwing of the set screw is finished, the cushion material is restored by restoring the lower goby. Since it is held between the bottom wall portion of the recess, it is possible to secure the allowance for the cushioning material, and there is a gap between the head of the set screw and the bottom wall portion. You can avoid the habit.

  Further, according to the fitting jig for fixing the roofing sheet material of the present invention, the fixing jig is sandwiched between the lower gozes on both sides, and the pair of legs that can stand on the surface of the roofing board material and the roof base material, respectively. And a connecting member connected to each upper end portion of the pair of legs, and the bottom wall of the connecting member is deformed very slightly by pressing the lower gob toward the base material of the roof. Since the screw holding part that keeps the set screw detachable is provided, the distance from the head to the roof base material is kept constant, the screw amount of the set screw is made constant, and the lower goby is tightened The height can be made uniform.

  Furthermore, according to the fitting jig for fixing the roofing sheet material of the present invention, the pair of legs can be rotated via a hinge to the leg main body directly connected to the connecting member and the end of the leg main body. The leg body is provided with a stopper that is slidably held along the leg body, and that supports the grounding piece in a non-rotatable manner by pressing the tip portion against the ground piece. Therefore, the fixing screw can be surely screwed and the jig can be easily removed by folding the leg portion by rotating the grounding piece.
