Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure and a method for mounting external members such as snow stoppers on an existing roof of a polymerization type.

[0002]

2. Description of the Related Art When mounting snow stoppers on an existing roof or supporting brackets for installing a solar water heater, a solar cell, or the like, such fittings (hereinafter referred to as "metal fittings"). In order to firmly fix the fixing portion of this “external material” on the roof, it may be necessary to partially process the existing roof.

[0003] For example, conventionally, when an external material is to be mounted on an existing roof of a polymerization type such as colonial, a method in which a part of the roof is peeled off and a fixing portion of the external material is directly fixed to the lower ground of the roof. Has been taken.

However, this method is troublesome, for example, by inserting a special tool like a rag between the roof materials that overlap one another up and down and groping out the nails fixing the lower roof material, which is troublesome. Has the disadvantage of requiring skill.

On the other hand, as a structure for attaching a snow stopper to an existing metal roof, there is a structure proposed by Japanese Utility Model Laid-Open No. 4-39226. As shown in FIG. 4, the fixing portion 2 of the snow stopper 1 is temporarily fixed on the roof material 3 via the adhesive tape 4, and then the fixing portion 2, the adhesive tape 4, and the roof material 3 are penetrated. Then, it is fixed on the base material 6 with the screw 5, and the cover 7 is screwed onto the fixed portion 2.

However, if this method is used for a roof of a polymerization type such as a colonial, the screws 5 penetrate through the overlapping portions of the upper and lower roofing materials. In this case, the through holes of the roofing material located on the upper side are sticky. Although water can be stopped by the tape 4, sealing is not performed on the through hole of the roof material located on the lower side, so that rainwater sprayed between the roof material and the upper roof material flows along the surface of the lower roof material. Therefore, there is a problem that the vehicle enters the room from the through hole.

The present invention has been made by paying attention to such conventional problems, and can be easily applied to an existing roof of a superposition type and has a mounting structure for an external material which is excellent in rain-catch performance. It is intended to provide a mounting method.

[0008]

In order to achieve the above-mentioned object, the invention of claim 1 attaches an external material to an existing roof having a roofing material of a superposition type laid on a roof substrate. The structure is such that a plate-like member having a sealing property is inserted on the back surface side of the roof material on which the fixing portion of the external material is arranged, and a fixing tool that penetrates the fixing portion, the roof material, and the plate-shaped member is provided. The external material is fixed to the roof substrate via the above.

According to a second aspect of the present invention, in the first aspect of the present invention, the fixed portion of the external member is covered with a cover member whose upper side is located on the back surface of the upper roof material.

Further, the invention according to claim 3 is a method of attaching an external material to an existing roof having a roofing substrate on which a superimposing type roof material is laid, wherein the roof is a mounting point of the external material. After arranging a plate-like member having a sealing property on the back surface of the material, after arranging the fixing part of the external material on the roof material on which the plate-shaped member is arranged, this fixing part is fixed by a fixing tool. This is a method of attaching an external material that is fixed to the base through the portion, the roof material, and the plate member.

[0011]

According to the structure for mounting an external material according to the first aspect or the method for mounting an external material according to the third aspect, a plate-like member having a sealing property is arranged on the back surface of the roof material at the mounting portion of the external material. Thereby, the through-hole of the upper roof material and the through-hole of the lower roof material are simultaneously closed between the upper and lower roof materials, and therefore, the intrusion of rainwater from each through hole to the indoor side is reliably prevented. .

Further, as a preliminary work for fixing the external material, it is only necessary to insert a plate-like member on the back surface of the roof material, and a troublesome work such as peeling off the existing roof with a special tool. Is unnecessary, that is, the external material can be fixed by a simple operation.

According to the second aspect of the present invention, the cover member covering the fixed portion of the external member improves the rain storability at the fixed portion and the through-hole portion of the upper roof member, so that the overall waterproofness is higher. The nature is demonstrated.
