Description

  The present invention can easily and quickly attach and assemble building boards, and can be firmly attached, and can exhibit excellent durability especially against negative pressure during strong winds. Related to brackets.

  In recent years, building plates such as various metal folded plate type roof plate materials and wall plate materials have been used. This kind of building board is fixed to a structural material such as a purlin, a trunk edge, etc. via a receiving metal fitting. As the connection structure between the building boards, there are a tightening type and a fitting type in which a cap material is used for connection. These connecting portions are performed via a hanging member, and the hanging member is fixed onto the receiving metal fitting. As described above, in the case where the building board is attached to the receiving bracket through the hanging element, both sides in the width direction of the building board are mountain-shaped such as a trapezoidal shape, and a flat valley-shaped portion is formed in the middle. When the negative pressure due to strong wind acts on the flat part of the valley shape, the wider the flat surface, the greater the negative external force acts, and the building plate is moved from the bracket. There is a good chance that it will be missed and thrown away.

  For this purpose, the receiving metal has been devised to firmly fix the building board together with the hanger. A device with such a device is disclosed in Patent Document 1. As a building board used in this Patent Document 1, a lower collar part is formed on one side in the width direction, an upper collar part is formed on the other side, and a lower collar part and an upper collar part of an adjacent building board, It is the type which tightens and connects.

Further, separately from the above, a squeezing coupling part having a symmetrical shape is formed on both sides in the width direction of the building board, and both squeezing coupling parts of adjacent building boards are coupled via a cap material. There is also a type that goes. In such a tightening-type envelope, a suspension is generally used as a fixing means for fixing the roof plate material to the metal fitting. Any of the building boards described above employs a hanging element.

  In Patent Document 1, a cutout portion is provided at a leg portion in addition to the hanging member of the metal fitting, and the protruding plate piece is bent and formed so as to protrude outward from the leg portion by the cutout. Further, a bent portion is formed on the building board side so as to fit with the protruding plate piece.

  And, the building plate is received by fitting the tip of the protruding plate piece into the bent portion formed on the upwardly inclined surface of the valley shape portion of the building plate arranged between the adjacent receiving metal fittings. Fixed to. With such a configuration, the building board is fitted and fixed by fitting the protruding plate piece and the bent portion together with the suspension.

  However, in Japanese Patent Application Laid-Open No. H10-227707, the metal fitting is appropriately bent from a single metal plate to form a main body portion of the metal fitting, and a part of the leg portion is cut away so that the protruding plate piece is cut through. In this way, it is bent outward. Since it is such a shape, especially when the metal plate is a thin plate, the protruding plate piece is naturally a thin plate, so when negative pressure due to strong wind is applied to the flat part of the valley of the building plate, It is fully possible that the projecting plate pieces will be deformed and the roof will be blown away as a result of being unable to withstand external forces.

  For this reason, if a metal plate is made of a thick plate to increase the durability of the metal fitting, not only will the weight increase, but a very strong pressing force will be required for the production of the metal fitting. Will also increase. From the above, the object of the present invention is sufficient to make the metal plate constituting the main body of the metal fitting thin, and to prevent the building board from being blown off from the metal fitting against the negative pressure caused by strong wind. It is to realize the wearing with durability.

  In view of the above, the inventor has intensively and intensively studied to solve the above problems. As a result, the invention of claim 1 is directed to the top portion and the leg portion that is formed outwardly downward and inclined from both sides in the length direction of the top portion. And a bracket main body having bent pieces formed inward from both sides in the width direction of the legs, a substantially flat substrate portion, and a winding formed on both sides in the width direction of the substrate portion And a fitting member that has a fitting protrusion that bulges from the surface of the substrate portion by cutting off a part of the substrate portion and has the cutting side as a fitting edge. The winding part is wound around the bent part of the leg part so that the part comes into contact with the leg part, and the fitting member is fixed to the leg part of the fitting body. Thus, the problem is solved.

  According to a second aspect of the present invention, in the above-described configuration, a locking portion is formed in the leg portion, and the fitting member is a receiving metal member that is locked to the locking portion. It solves the problem. According to a third aspect of the present invention, in the above-described configuration, the base portion of the fitting member is a receiving bracket in which a locking portion that is locked with a locked portion of the receiving bracket main body is formed. It solves the above problems.

  According to a fourth aspect of the present invention, in the configuration described above, the locking portion is formed to bulge on the back side of the substrate portion, and the locked portion is formed as a through hole in the leg portion. As a result, the above-mentioned problems have been solved. According to a fifth aspect of the present invention, in the above-mentioned configuration, the fitting end edge of the fitting member is a receiving metal fitting in which only a tip end portion of the fitting protrusion portion protrudes downward. Thus, the above problem is solved.

  According to a sixth aspect of the present invention, in the above-described configuration, a presser piece is formed by being cut across the cut side and the lower end of the base plate portion of the fitting member, and the presser piece is pressed against the leg portion; As a result, the above-mentioned problems have been solved. The invention of claim 7 solves the above-mentioned problem by adopting a receiving metal fitting in which the plate thickness of the fitting member is formed larger than the plate thickness of the receiving metal fitting body in the above-described configuration. The invention of claim 8 solves the above-mentioned problems by adopting a receiving metal fitting in which a hanging member for connecting adjacent folded roof plates is attached to the top portion in the above-described configuration.

And a fitting projection that bulges from the surface of the substrate portion and has the cutting side as a fitting edge.

  Therefore, even if negative pressure due to strong wind is applied to the building plate fixedly supported by the metal fitting, the metal fitting body can withstand sufficiently because the negative pressure is applied upward, and the fitting member is the metal fitting. Since it is fixed as a separate member from the main body, the building board can be supported and fixed by the metal fittings very firmly. According to a second aspect of the present invention, in the above-described configuration, a locking portion is formed in the leg portion, and the fitting member is locked to the locking portion, whereby the leg portion of the metal fitting main body. It is possible to make the fixing even stronger.

  The invention of claim 3 can be in a surely locked state by forming a locking portion that locks with the locked portion of the metal fitting body on the base plate portion of the fitting member, The mounting can be made even stronger. According to a fourth aspect of the present invention, the locking portion is formed to bulge on the back side of the substrate portion, and the locked portion is formed as a through hole in the leg portion. In addition to being able to be stopped, it is only necessary to form a through-hole on the leg side, and the structure can be extremely simple.

  According to a fifth aspect of the present invention, the fitting edge of the fitting member is fitted so as to bite into the bent portion of the building board by forming a protruding edge in which only the tip portion projects downward. Thus, a very strong fitting portion structure can be obtained. According to the sixth aspect of the present invention, a presser piece is formed by cutting off the cut-out side and the lower end of the base plate portion of the fitting member, and the presser piece presses against the leg portion, whereby the fitting member is wound around the winding portion. It can be very firmly fixed to the leg part together with the part.

  According to the seventh aspect of the present invention, the thickness of the fitting member is larger than the thickness of the metal fitting body, so that the thickness of the fitting member is large even if the metal fitting body is formed from a relatively thin metal plate material. By attaching the fitting member to the leg portion of the metal fitting body, it can be made a strong and durable metal fitting, and the metal fitting body is formed of a thin metal plate as described above. The bracket itself can be reduced in weight. In the invention according to claim 8, it is easy to mount the building board by attaching a hanging member for connecting the adjacent folded plate roof boards to the top part.
