[Problems to be solved by the invention]
By the way, such a water drainage piece formed on a metal sheet roofing material is located below a joint between the insertion protrusion and the insertion recess, and rainwater infiltrates from a joint between the metal sheet roofing materials. It functions as a water receiving part when it is done, and normally, by forming a plurality of water draining convex parts on the substrate part of the water draining piece, it is possible to prevent the infiltrated rainwater from moving laterally and reaching the roof foundation. It is devised.
[0006]
However, when the roof slope is gentle, or under bad conditions such as heavy rain or storms, drainage is not instantaneous, and rainwater may move laterally over multiple drainage protrusions and leak. Was. In addition, such leaks can cause rainwater to drain due to negative pressure due to convection of air inside the roof, which occurs due to the temperature difference between the indoor and outdoor areas, when the adhesion between adjacent roof material bodies is not sufficient. Sometimes it was caused by being sucked up from a piece.
[0007]
Accordingly, an object of the present invention is to provide an improved metal sheet roofing material that can reliably drain water and effectively prevent water leakage even when rainwater reaches the water cut piece due to severe bad weather. The point is to provide.
[0008]
[Means for Solving the Problems]
According to the structure of claim 1, the insertion piece is integrally formed at one end of the roofing material main body, and the drain piece is continuously provided at the other end, and is formed by the continuous portion and the drain piece. The insertion recess is provided, and in the above-described water drainage piece, in a metal sheet roof material in which a plurality of water drainage protrusions are formed, the water drainage piece is provided with a water return part formed by folding up the end end thereof upward. It is characterized by having.
[0009]
According to the configuration of claim 1, since the water return portion is formed by folding the end end of the water drainage piece upward, even if rainwater enters the water drainage piece from the insertion recess due to bad weather, the rainwater lateral movement direction. The water return portion formed after the plurality of water draining protrusions in (1) functions as an inundation barrier, and can prevent rainwater from entering the back side of the roofing material. Therefore, the effect of preventing rainwater from entering is enhanced, which is particularly effective when the roof slope is gentle or when the weather is severe.
[0010]
In addition, since the strength and rigidity of the end portion of the water drainage piece are enhanced by the folded structure of the water return portion, downward bending when external force is applied to the end portion becomes smaller than before, and the end of the joint portion A gap is avoided or suppressed. That is, when the insertion protrusion of the adjacent roof material is inserted into the insertion recess, the base end of the insertion protrusion is supported from below by the water return portion, so that there is no gap between the joints. Therefore, the waterproofness is good, and the strength of the joint is improved.
[0011]
According to a second aspect of the present invention, in the configuration of the first aspect, a locking piece for a fly is formed on the roof material main body side and on the upper and lower edges of the drainage piece.
[0012]
According to the configuration of claim 2, since the locking piece for the cold is formed on each of the roof material main body side, the upper end edge and the lower end edge of the water drainage piece, when the metal sheet roof material is laid on the roof foundation. The upper and lower adjacent metal plate roofing members can be connected in the vertical direction by fitting the corresponding locking pieces for the cold and then crimping them together. As a method of connecting in the vertical direction, a staggered arrangement in which the left and right ends do not overlap each other or a linear arrangement in which the left and right ends are matched can be arbitrarily set.
[0013]
According to a third aspect of the present invention, there is provided a roofing member made of a metal plate, in which a protruding piece is formed at one end and a continuous portion is provided at the other end, and a continuous portion is provided at one end. Provided, and at the other end, a drain piece is continuously provided, an insertion recess formed by the continuous portion and the drain piece is provided, and further, a plurality of drain projections are formed on the drain piece. And a second metal sheet roof material having a water return portion formed by folding the end end thereof upward, the other end of the first and second metal sheet roof materials, and one side end Are connected to at least one or more intermediate roof members formed on both sides of the connecting portion to be connected to the connecting portion provided at the second position.
[0014]
According to the configuration of claim 3, the first metal plate roofing material in which the insertion protrusion is formed on one side end, and the second metal plate in which the drainage piece having the water return portion is formed on the other side end The metal sheet roofing material is constructed by combining three types of roofing members consisting of a roofing material and an intermediate metal sheeting roof material which can be freely connected to each of the two roofing materials. In addition to the above-described effects, the following effects can be obtained.
[0015]
In other words, since three types of metal sheet roofing materials are connected in series, a long metal sheet roofing material can be easily formed, thereby connecting the roof projection with the insertion projection and the insertion recess. It becomes possible to reduce the number of installation parts. When constructing a long metal sheet roof material, it is only necessary to caulk and connect the continuous portions of each roof material, and processing work at the time of factory manufacturing is easy. In addition, if the first metal roofing material, the second metal roofing material, and the intermediate roofing material are formed to have the same dimensions as each other, by stacking these three types of roofing materials, space can be saved when handling in a factory. Instead, the overall length of the metal sheet roofing material as the final product can be set to an arbitrary length.
