Description

TECHNICAL FIELD The present invention relates to a heat insulating and waterproofing device for a thatched roof.

Conventional technology Conventionally, to renovate thatched-roof thatched roofs, a new roof plate made of the same material as the old roof plate is used to cover the roof from above, or a tarpaulin is attached from the top according to the shape of the old roof plate. Method was implemented. However, according to the former method, there is a problem that the meshing portion of the new roof plate, that is, the seam, tends to come off. Further, according to the latter method, it takes a lot of time and effort to attach the waterproof sheet, and if the base roof plate is corroded, a joint failure occurs, resulting in poor durability of the modified roof.

Therefore, as a method of remodeling the above-mentioned straw rod roof, the present applicant first spreads a heat insulating material on the whole roof so that the heat insulating material is spread over the straw rod, and at a required portion of the heat insulating material, a large number of joining pieces having a sheet joining surface are provided. After fixing these joint pieces to the straw bars on the roof from above the heat insulating material and holding down the heat insulating material, cover the surface of the heat insulating material with a waterproof sheet, and then join the required parts of the waterproof sheet. We proposed a method of joining to
See 131260).

However, in the previously proposed method, since the heat insulating material is arranged over the straw rods, the heat insulating material floats above the roof plate between adjacent straw rods. In this state, a hollow part is formed. Therefore, when the waterproof sheet is covered on the surface of the heat insulating material and the waterproof sheet is stretched, the heat insulating material is damaged by the weight of the worker. There was a problem.

Further, conventionally, the adjacent metal plates are connected to each other by the rising connection part, and the existing metal plate thatched roof formed on the rising connection part having the reinforcing rib structure consisting of the double and triple heavy-duty structure is directly used as the base structure part for the new roof formation. None, after laying a heat insulating material also serving as a rust transfer prevention member from the same roof on the existing metal sheet roof surface, directly or indirectly attaching a roof surface member for forming a new roof to the roof, In addition to forming the main part of the surface member into a laminated integrated structure that is separated from the existing metal sheet roof by a predetermined distance, the roof surface member is fixed to the existing metal sheet roof rising connection part of the reinforcing rib structure. The repairing method is already known (for example, see Japanese Patent Publication No. 56-50066).

However, according to this conventional method, on the existing metal plate thatched roof, a base plate made of a base plate, plywood, etc. is bridged,
After forming a new roof forming base structure part and laying a heat insulating material, just roofing the new roof forming roof surface member,
In other words, the roof structure has a double metal plate roof, which is not only very expensive, but also the weight of the roof itself is heavy, which causes a large load on the structural materials such as columns.

The purpose of this invention is to solve the above-mentioned problems of the prior art, and when performing the work of tensioning the waterproof sheet, the insulating material is not damaged at all, and the workability is very good. Insulation and waterproof repair work can be easily and surely performed, and the roof with a metal plate roof does not have a double structure, the cost is low and the weight of the roof itself hardly increases, and the structure of pillars etc. There is an attempt to provide an insulating and waterproofing device for thatched roofs that does not impose a large load on the timber.

Means for Solving the Problems In order to achieve the above-mentioned object, the first aspect of the invention is to provide a heat insulating and waterproofing device for a thatched roof that is made up of a required number of metal roof plates and adjacent roof plates. In a thatched roof made up of a straw rod part interposed between, in the recessed portion between the straw rod parts that are adjacent to each other,
A heat insulating material having a height substantially the same as the height of the straw rod portion is fitted, and on the upper surface of the heat insulating material and the straw rod portion, a thermoplastic synthetic resin film, or a foamed sheet of the resin, and further a foamed sheet of these resins, A joining piece which is covered with a base sheet made of a resin film, a composite sheet with a woven fabric or a non-woven fabric, and has a width larger than the width of the straw rod portion and a sheet joining surface on the upper surface at a required position of each straw rod portion. Is fixed, the heat insulating material and the base sheet are held together by these joint pieces, and the waterproof sheet is covered on the surface of the base sheet and the joint piece that covers all the straw rod parts and the heat insulating material, thereby making it waterproof. It is characterized in that required portions of the sheet are joined to the sheet joining surface of the joining piece.

According to a second aspect of the present invention, in the above-mentioned straw rod roof, a thick heat insulating material having a height exceeding the height of the straw rod portion is fitted into a recessed portion between the straw rod portions adjacent to each other, Each straw bar portion is covered with a thin wall insulation material having a height approximately equal to the height from the upper surface of the straw bar portion to the top surface of the thick wall insulation material, and all the thick and thin insulation materials and the top surface of the straw bar portion.
