Description

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

  Folded plate roofing material is a product that is originally formed from steel sheet coils and formed into a desired shape and length using a roll forming machine installed at the construction site. 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 demand for rapid forming and construction of folded-plate roof materials at construction sites. There are many things, and it is often difficult to perform molding and construction (for example, securing a place).

  As a breakthrough, recently, the roof has been formed by molding it into a predetermined shape and a predetermined length under the length that can be transported in the factory in advance (standard size, sizing), and connecting them at the construction site. Roof materials and construction methods that enable construction have been developed.

  However, the roof of the folded plate structure has a large area and has many gentle slopes, and it is particularly difficult to ensure water-stopping.

  For this reason, in the past, non-uniform seals, so-called caulking materials, have been used to ensure water-stopping properties.However, when the caulking materials deteriorate or are cut due to the expansion and contraction of roofing materials due to sunlight or cold air. There is still concern about the leaking of rain, and there is still room for improvement.

  As a prior art for solving the above-described problems, Patent Document 1 includes fastening a horizontal member disposed across at least two mountain parts formed in a facility state of an exterior material to a holding member, There has been proposed a structure in which a pressing portion is provided on the horizontal member, and the overlapping portion of the exterior material is pressed by the pressing portion.

  Patent Document 2 discloses a structure in which a pressing member is disposed in a valley formed in the facility state of the exterior material, and the end portion of the exterior material is held in a pressed state from above by the pressing portion of the pressing material. Things have been proposed.

  Further, Patent Document 3 discloses a backing material that is formed on the back surface of the ridge side end on the back surface of the ridge side of the regular folding plate in which the peak portion and the trough portion are alternately formed. According to Patent Documents 4 to 6, a plurality of protrusions (beads) are provided on the ridge side end side of the support receiving portion of the roof plate body to prevent intrusion of rainwater. Further, in Patent Document 7, a pressing member is disposed on a superposed joint portion of a building plate material, and the building plate material is penetrated by a plurality of joint portions such as a drill screw and a fixing tool. There has been proposed one that is fixed to a support plate of a joint support material provided on the lower side.
