Description

  The present invention relates to a folded plate roof material, a folded plate roof material connecting structure, and a connecting fixture used for the connection, which are widely used in large-area roofs of factories, warehouses, large stores, and the like.

  Folded plate roofing material is made of a main body and steel plate coil, and is formed into a desired shape and length using a roll forming machine placed at the construction site. Workability, wind pressure strength, waterstop Is widely used as a roofing material that can be economically secured.

  By the way, in recent years, there is an increasing demand for repairing existing folded-plate roofs, and there is a need for rapid forming and construction of folded-plate roof materials at construction sites. In some cases, it is often difficult (such as securing a place) to perform molding and construction.

  As a breakthrough, recently, there is a roofing material and construction method in which it is molded into a predetermined shape with a length that can be transported in the factory in advance (sizing), and this is joined at the construction site to lift the roof. As a prior art in this respect, reference is made to a vertical roofing material as disclosed in Patent Document 1 or a joint structure of building boards as described in Patent Document 2.

Consisting of
Is preferable as a specific means for solving the problems of the present invention.

  Further, the present invention is a connection structure of folded plate roofing material having the above-described configuration, wherein the lower goby and upper goby are placed on the upper goby and lower side of another folded plate roofing material arranged adjacent to each other in the eave-ridge direction. The roof material is connected to the eaves-ridge direction by fitting each with a goby, while the joint portion is linked to the joint portion of another folded plate roof material arranged adjacent to the eave direction to connect the roof materials to each other. It is the connection structure of the folded-plate roof characterized by being formed.

  Furthermore, the present invention relates to a folded plate roof material having the above-described configuration, and in the connecting fixture used to connect the folded plate roofs to each other at the fitting portion of the upper goby and the lower goby, the fixing of the roof A folding plate roofing material having a bolt that is linked to a portion, a receiving plate that is located on the lower surface of the shoulder portion of the folded plate roofing material, and an opening that penetrates the bolt. And a nut that engages with the bolt at the top of the pressing member and clamps the shoulder between the backing plate and the pressing member by tightening the pressing member. The pressing member is formed in a concave portion that faces the fitting portion of the lower and upper goby of the folded plate roofing material and positions the fitting portion on the inner side thereof, and at least four places on the front, rear, and right and left of the concave portion. Provided on each shoulder of the folded roof material to be connected A coupling fixtures used for connection of the folded sheet roofing, characterized in that it consists of those consisting of the pressing legs in contact.

  In the connection fixture having the above-described configuration, it is preferable to provide a cover that is detachably fitted to the pressing member and accommodates the pressing member in its inner space. Moreover, this invention comprises the connection structure of a folded-plate roof material by connecting the said roof materials mutually in the fitting part of the said upper goby and the lower goby using the connection fixture which consists of said structure. It is preferable to do this.

  In the folded plate roof material of the present invention having the above-described configuration, the short side (water upper end side) located on the ridge side of the bottom plate part, the edge of the inclined side plate part connected to this short side, the edge of the shoulder part, and the rising edge A saddle-shaped shape that can be fitted to an upper goby of another folded plate roofing material that is formed by folding 180 ° upward at any one or all of the edges of the section and arranged adjacently along the eave-ridge direction.
