Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet covering method for covering a roof portion of a structure when the roof of the structure is repaired, and a sheet connecting tool used in the sheet covering method.

[0002]

2. Description of the Related Art For example, when repairing the roof of an existing structure, it is necessary to once dismantle and remove the old roof material of the structure, and then install a new roof material. Therefore, in order to prevent rainwater from entering the structure when the old roofing material is removed, it is necessary to cure the entire structure with rain. Conventionally, a curing sheet is provided on the entire roof of the structure. (Blue sheet or disaster prevention sheet) is used to cover the cover.

[0003] In the conventional sheet covering method, a shed frame is formed above the roof of a structure by using a plurality of pipes and a clamp for joints for connecting the pipes to each other. The eyelet (annular small washer) was tied to a pipe through a rope, and the sheet was stretched so as to cover the entire upper part of the structure to prevent rainwater from entering.

[0004] However, in the conventional sheet covering method, the clamp for the pipe joint may come into direct contact with the sheet, so that the sheet is rubbed by the wind and the clamp and the sheet are rubbed, and the sheet is damaged. Sometimes. Also, since the sheet is only tied to the pipe using a rope etc., the fixing of the sheet is unstable,
There is a problem that it easily comes off.

Further, when carrying in materials from the roof of the structure, it is necessary to remove the sheet and open the upper side of the structure.
It is necessary to attach and remove the sheet by unwinding, which requires a lot of labor for the operator. In addition, when attaching and detaching the seat, it is necessary for the worker to climb on the roof of the structure, which involves dangerous work.

In addition, since seams and eyelets of the sheet cannot be kept water-tight, there is a problem that rainwater leaks from this part in rainy weather. Furthermore, when an angle material other than a pipe, a channel material, or an H-shaped steel material is used as a member constituting the shed frame, it is difficult to tie the rope, and further, the rope is made of the above-mentioned steel materials. There is a problem that the rope is broken due to rubbing at the edge portion.

[0007]

As described above, in the conventional sheet cover method, the following problems have occurred. (A) Since the pipe joint clamp and the sheet are in direct contact, the sheet is damaged. (B) Since the sheet is merely tied to the pipe using a rope or the like, the sheet is likely to come off. (C) It is not easy to open and close a part of the shed, and a lot of labor is required to carry in materials and the like from the shed. (D) When attaching / detaching the sheet, the worker needs to go up to the roof of the structure, which involves dangerous work. (E) Rainwater leaks from seams and eyelets of the seat. (F) When an angle material, a channel material, an H-shaped steel material, or the like is used as a member forming the shed frame, the rope may be rubbed against the edge, and the rope may be cut.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to spread a sheet by a simple operation and cover the upper part of a roof of a structure.
