Description

INDUSTRIAL APPLICABILITY The present invention uses a fitting roofing material for roofs of general houses, offices, condominiums, welfare facilities, resort facilities, etc., with vertical roofing as a suitable example, and particularly a heat insulating material as a core material. It relates to a sandwich type fitting roofing material sandwiched between the roofing material and the endothelial material, and a joining structure using the fitting roofing material.

The sandwich-type roofing material, in which the core material is sandwiched between the exodermis material and the endothelial material, has higher heat insulation performance, is lighter, and is stronger than the vertical roofing material that is used by molding a single long metal plate. It has strength, durability, and sound deadening properties, and its demand has tended to increase in recent years.

In such a fitting type roofing material, particularly for vertical roofing, an upper haze provided at the end on the long side of one roofing material is conventionally provided at the end on the long side of the other roofing material. By fitting it to the provided lower haze, adjacent roofing materials are connected in the girder direction, and the upper joint provided at the short side end on the water upper side of the roofing material and the short on the water side. A method of connecting roofing materials in the direction between beams by linking lower joints provided on the side sides with each other has been developed (Patent Documents 1 and 2).

By the way, this kind of roofing material is, for example, a fitting type roofing material for vertical roofing using an upper goby and a lower goby, and as shown in FIGS. 7A and 7B, the lower goby and the lower goby. It has been proposed that a waterproof material S is interposed in a gap at a fitting protrusion with an upper goby to impart waterproofness. By adopting such a configuration, conventionally, rainwater that invades indoors from the joint portion between the upper goby and the lower goby is prevented.

However, if only the conventional waterproof measures are adopted, heavy rain will increase the water level near the eaves and cause rain leaks, or the snowmelt water seen in heavy snowfall areas will cause "leakage" (that is, roofs). In the case of the above snowmelt water accumulating due to the ice embankment (dam) at the eaves and causing rain leakage), there was a problem that the measures against water leakage were not perfect.

Therefore, an object of the present invention is a sandwich type fitting type roofing material which enables rainwater inevitably infiltrating from a seam between roofing materials to be drained to the outside without leaking indoors, and a fitting type roofing material thereof. The purpose is to propose a joint structure using.

In view of the above-mentioned problems and as a result of diligent studies to achieve the above object, the inventors first of all have a rectangular roof having a sandwich structure in which a core material is sandwiched between the exodermis material and the endothelial material. It is a fitting type roofing material in which an upper or lower brace is provided on the edge of each long side of the material body.
One roofing material main body and the other roofing material main body to be connected adjacent to the one roofing material main body are joined by fitting the lower goby and the upper goby provided on the respective side edges. An idle space is provided between the side ends of the roofing material, and the outer surface of the roofing material main body on the side forming the lower goby, which is formed along the long side edge of the roofing material main body in the idle space. We have developed the present invention, which comprises a fitting type roofing material, which comprises a hidden gutter which is integrally molded into a groove shape in a cross section by extending the free end portion of the outer skin material which is covered with the roofing material. did.

Secondly, in the present invention, an upper goby or a lower goby is provided at the edge on the long side of each of the rectangular roofing material main body having a sandwich structure in which the core material is sandwiched between the exodermis material and the endothelial material. When joining the mating roofing material in the girder direction,
One roofing material main body and the other roofing material main body to be connected adjacent to the one roofing material main body are joined by fitting the lower goby and the upper goby provided on the respective side edges. An idle space is provided between the side ends of the roof, and the upper goby and the lower goby are separated from each other by interposing a groove-shaped hidden gutter formed by extending the outer skin material on the lower goby side in the idle space. We propose a joining structure of a fitting type roofing material, which is characterized by being fitted and joined.

Further, in the fitting type roofing material and the joining structure of the fitting type roofing material according to the present invention having the above structure, further
(1) The hidden gutter has a seat surface in contact with the surface of the base material.
(2) The hidden gutter has an upright weir on the free end side of the cross-sectional groove shape, and a base material fixing portion is provided at the extending position of the upright weir.
(3) The hidden gutter is provided so that a part of the hidden gutter is accommodated in a recess provided by omitting the core material side end portion of the upper goby side roofing material main body.
