Description

  The present invention relates to a connection structure for roof materials, particularly folded plate roof materials, which is widely used in large-area roofs such as factories, warehouses, and large stores.

  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 also concern that rain leaks will occur.

There has been proposed a structure in which an opening for drainage is formed, a vent is formed in a peak portion of the second packing, and a drainage port also serving as ventilation is formed in a valley portion.

  In addition, Patent Document 2 discloses that a ridge side end of a lap connection portion is interposed between a ridge side end portion and an eave side end portion at an intermediate portion in the ridge eave direction in the lap connection portion of the roof plate. A structure is proposed in which a draining space is formed over the entire length of the section, a face door is provided at the end of the eaves side of the draining space, and a watertight seal band is provided in the draining space over the entire length in a direction substantially perpendicular to the ridge eave direction. ing.

  In addition, a plurality of folded plate roofing materials are arranged side by side in the vertical direction of the roof gradient, and the lower end portion of the upper folded plate roofing material is overlapped with the upper end portion of the lower folding plate roofing material via a ventilation gap. The upper and lower folded plate roof material overlapping portions are fastened to a support member on the roof structure material, and the fixed airtight material covering the ventilation gap at the upper edge of the lower folded plate roof material is formed into the fixed airtight material. In the groove formed on the upper end edge, it is fitted to the upper edge, and at the lower end edge of the upper folded plate roof material is provided a fixed water stop material that covers the ventilation gap.
