Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention applies a surface material for makeup such as tile blocks as a roofing material for roofing,
The present invention relates to a double thatched roof having a waterproof roofing roof material formed on the back side thereof.

[0002]

2. Description of the Related Art Conventionally, in Japan, a roofing material, a roof tile roof or a roofing roof made of a metal plate is generally used. In Europe and America, stone roofing materials such as natural slate and simple roofing materials such as tiles such as tile blocks are also used for roofs. However, in areas with a lot of rain such as Japan, roofs using roofing materials such as stone materials and tile blocks have been considered unsuitable because of their poor rain-sealing performance. However, in recent years, roofing materials are highly diversified, and roofing materials such as stone materials and tile blocks have been demanded for design reasons.

In order to meet the above-mentioned demand, the inventor has previously proposed a double thatched roof disclosed in Japanese Patent Laid-Open No. 63-265050. As shown in FIG. 5 and FIG. 6, this double-roofed roof is provided with a large number of roofing roofing materials 1 made up of tile blocks for surface makeup and a lowering roofing material 2 for waterproofing. Are fixed on a roof support member 3 such as a purlin material, and ridge portions 4 along the flow direction are formed on the underlaying roof material 2 at required intervals in the left-right direction, and engagements provided on the upper surfaces of these ridge portions 4 are formed. Hole 4
By engaging the locking claw 5a of the locking member 5 provided on the upper surface of the protruding portion 4 with a, the locking member 5 is fixed on the protruding portion 4, and the upper roofing is attached to these locking members 5. The bottom surface of the roofing material 1 is locked, and the eaves side of the roofing roofing material 1 on the ridge side is overlapped with the ridge side edge of the roofing roofing material 1 on the eaves side, and laminated from the eaves side to the ridge side. Is.

This double-roofed roof does not always have sufficient rain-sealing performance at the overlapping portion of the upper roofing material 1 made of tile blocks, and even if rainwater or the like enters below them, that is, inside the room, The roofing material 2 is guided to the recesses 6 between the ridges 4 and is made to flow down to the eaves side and discharged from the eaves side.

[0005]

The conventional double thatched roof is constructed as described above, and the ridge portion 4 of the lower thatched roof material 2 is used.
Since the upper surface is provided with the engaging hole 4a, rainwater or the like during a storm is transmitted along the lower surface (rear surface) of the roofing roofing material 1 between the lower surface and the upper surface of the ridge portion 4, and the engagement is performed. Hole 4a
There is a case where water leaks slightly from the inside to the inside of the room, and in particular, when both side edges of the adjacent thatched roofing materials 2 are connected on the ridge portion 4, water may leak from the connecting portion to the inside. There was a problem. Even if an upper roofing material such as a tile block or a natural slate is tightened and fixed on the ridges of the lower thatching roofing material with a fixture such as a screw, the screw holes are screwed into the interior of the room. It was difficult to prevent water leaks to.

The present invention solves the above-mentioned problems of the prior art, and even when a roofing roof material such as a tile block or a natural slate that does not have sufficient rain-sealing performance is used, water leaks from the lower roofing material to the inside. The purpose of the present invention is to provide a double thatched roof structure that can reliably prevent the occurrence of damage. Another object of the present invention is to provide a double thatched roof structure capable of firmly supporting and fixing the upper roofing material on the roof support member.

[0007]

The double-roofed roof structure according to the present invention has a waterproof thatched roofing material having raised portions formed on the left and right edges of the roof, which is laid on a base and adjacent to each other. In a double thatched roof structure in which a suspension member is arranged between the lower thatched roof materials, and a surface cover is fixed on the suspension member, and then the surface material is fixed, the suspension member is fixed to the base as the suspension member. A fixing groove formed of a fixing portion and standing portions rising on both right and left sides thereof and a rising portion of the lower thatched roof member formed from above between the standing portion and a hanging portion bent outward from the upper end of the fixing portion. On the other hand, the joint cover is provided with an engaging groove portion to be fitted and an attaching portion for fixing the surface material while forming an outer groove portion rising from the lower end portion of the engaging groove portion and the hanging portion. , Made from long threading material in the flow direction And it shall be deposited on the retaining clips member in a manner to cover the fixing groove of the retaining clips member from above.

According to the double-roofed roof structure, the joint cover, which is long in the flow direction, is located on the upper part of the suspension member which is located between the lower thatched roof materials adjacent to each other in the left-right direction and which fixes the roof materials. In addition, since the joint cover covers the fixing groove portion of the suspension member from above including the locking structure portion of the locking groove portion of the suspension member and the rising portion of the underlaying roofing material, Even if rainwater enters through the gap between the surface material attached to the section and the hanger member, this rainwater will enter the room side through the gap between the hanger member and the starting part of the roofing roof material. Without such a situation, the drip is dropped on the outer groove portion of the suspension member or further on the surface of the thatched roof material outside thereof. Therefore, the rainwater flows toward the eaves along the outer groove or the upper surface of the roofing roof material, and is reliably discharged from the eave side end to the outside.

In the double-roofed roof structure, by forming a drainage hole at the groove bottom of the outer groove of the suspension member, rainwater can be released onto the lower thatched roof material through this drainage port. Therefore, it is possible to avoid the possibility that rainwater concentrates only on the outer groove portion and causes water leakage to the indoor side.

Further, the lower end of the mounting portion forming the outer groove portion of the suspension member is formed so as to abut against the upper surface of the underlaying roof material in a state of being mounted on the base material, so that the mounting portion is formed. Since the surface material is supported by coming into contact with the base material from above through the lowering roof material, the roof strength can be improved against a load acting from above the surface material.
