Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin flat roof material and a method for constructing a resin flat roof material.

[0002]

2. Description of the Related Art As conventional roofing materials, there are roofing materials such as ceramics, cement, asbestos slate, synthetic resin and metal.

A conventional flat roof material and a method of constructing a flat roof material will be described below with reference to FIG. As shown in FIG. 9, the flat roof member 31 is a flat roof member having a rectangular outer shape. In addition, the conventional flat roof material is made to have a thickness of about 5 mm to 20 mm in order to reduce the load on the building because of its earthquake resistance and workability.
The one that can be constructed by stacking from the top is widely used.

A construction method is as follows. A base plate 32 is laid on the roof surface, and a sheet-shaped roofing is laid as a waterproof material 33 on the base plate 32 to form a roof base material 34. The flat roof material 31 on the left and right sides from the eaves side 35, respectively, in the nail holes 3 of the flat roof material 31.
Nail 37 was struck on 6 and fixed directly to roof base material 34,
Then, the flat roof material 40 of the upper tier is superposed on the non-exposed portion 39 of the flat roof material 38 of the lower tier, and the exposed portions 41 of the flat roof material 38 of the lower tier are sequentially directed toward the ridge side 42 so that they appear. It was general that they were installed in series.

[0005] This flat sheet roofing material has variations in strength due to the material strength of the flat sheet roofing material when a person rides on it and constructs it, for example, during continuous construction. In particular, large-sized flat roofing materials such as pottery and cement had variations in strength. Conventionally, in order to secure the strength of the roof material, particularly the strength that does not cause a crack when a person steps on the roof material, a material having a thick plate or a backing material on the back surface has been used.

However, in such a flat roof material, increasing the plate thickness increases the material cost and makes it difficult to reduce the weight, or using a back-up material on the back side increases the cost, which is troublesome for construction. There was a problem.

[0007]

[Problems to be Solved by the Invention] As described above,
A problem with the conventional flat roof material is that if a flat roof material made of earthenware, cement or the like is used to increase the size, the weight becomes large and the construction becomes difficult. Therefore, we will create a resin flat plate roofing material that can be made large in size and lightweight, has strong cracking resistance, is less likely to cause dew condensation, has good workability, and can also improve wind resistance after construction. There was a need.

[0008] The problem to be solved by the present invention is a flat roof material having a large size and a light weight, and having a robust strength that does not crack when trampling. Ventilation occurs to prevent condensation,
The fixing method is to make the construction easy and further improve the wind resistance after the construction.

[0009]

In order to solve such problems, the present invention provides a plurality of abutting piers on the back surface of a resin flat plate roofing member main body, which are substantially the same as the pier width pitch. The reinforcing ribs were provided, and between the reinforcing ribs, the reinforcing ribs that abut the upper surface of the roof base material were provided.

Further, a plurality of piers are fixed at equal intervals in the flow direction on the roof base material, and reinforcing ribs provided on the back surface are placed on the piers, and the lower resin flat plate roof material main body is placed. The rear end portion is fixed to the roof base material by the fixing portion of the clip having the substantially upward engaging portion and the fixing portion, and then to the engaging portion of the clip on the resin flat plate roof material main body in the lower stage, By means of a construction method in which the front end portion of the upper resin flat plate roofing material main body is fixed while being locked.

As a result, even if it is a large size, it is lightweight and secures the crack resistance against trampling, and due to the construction method of the piers, natural ventilation occurs in the ventilation layer between the piers to improve the breathability and prevent dew condensation. The clip fixing and the reinforcing rib structure improve the workability such as ease of stacking and nailing, and further enhance the wind resistance after the work.

In the resin flat roof material according to the first aspect of the present invention, a plurality of reinforcing ribs having the same height and abutting against the pier are provided on the back surface of the resin flat roof main body so as to be substantially the same as the pier width pitch. It is provided in the flow direction.

Therefore, it is possible to secure the stepping crack strength while reducing the weight. Further, the piers allow natural ventilation in the ventilation layer between the piers to improve the air permeability and prevent dew condensation.

According to a second aspect of the present invention, there is provided a resin flat roof material having a plurality of heights on the back surface of the resin flat roof material, which are substantially the same as the width width of the pier, and which are in contact with the pier. The same first reinforcing ribs are provided, and second reinforcing ribs that come into contact with the upper surface of the roof base material are provided between the first reinforcing ribs.

Therefore, it is possible to increase the strength of the step crack while reducing the weight.

According to a third aspect of the present invention, the resin flat sheet roof material is one in which the bottom surface of the reinforcing rib according to the first or second aspect is hung vertically so as to match the roof slope.

Therefore, when a load is applied, the bottom surface of the rib is widely brought into surface contact with the roof base material so that the load can be evenly received and the strength of the resin flat plate roof material against the load can be increased. . That is, it is possible to increase the strength of stepping cracks during construction.

In the resin flat sheet roofing material according to claim 4, the reinforcing ribs of the resin flat sheet roofing material according to any one of claims 1 to 3 are provided at the front and rear of the back surface side of the resin flat sheet roofing material body. It is formed excluding.

Therefore, the workability such as the ease of stacking and the ease of nailing can be improved.

According to a fifth aspect of the present invention, there is provided a resin flat plate roofing material construction method, in which a plurality of piers are fixed at equal intervals in a flow direction on the eaves side on a roofing base material in which a waterproof material is laid on a base plate. While abutting the side end surface of the lower resin flat plate roofing material on the pier, while mounting the reinforcing ribs provided on the back side, separate resin flat plate roofing materials are continuously provided in the left-right direction, The rear end portion of the lower resin flat plate roof material is fixed to the roof base material by a fixing portion of a clip having a substantially upward engaging portion and a fixing portion,
After that, while locking the front end of the upper resin flat plate roof material to the clip locking part on the lower resin flat plate roof material,
Similar to the lower resin flat plate roofing material, the side end surfaces of the upper resin flat plate roofing material are abutted in the left-right direction and fixed,
It will be installed in sequence toward the building side.

Therefore, due to the construction method of providing the pier, natural ventilation occurs in the ventilation layer between the piers, the air permeability of the roof can be improved, and the dew condensation hardly occurs. In addition, the fixing method using a clip can improve workability such as ease of stacking and nailing. Furthermore, wind resistance after construction can be improved.
