Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary roof and its construction method.
It is related to the temporary roof and its construction method to protect from wind and snow and to smooth the work.

[0002]

2. Description of the Related Art Since most civil engineering and construction work is performed outdoors, it is affected by natural conditions such as rain, wind, and snow, and the operation rate is extremely low during rainy seasons and winter constructions in cold regions. This is a factor that causes delays in the process or an increase in construction costs due to a decrease in operating rate. Further, outdoor work in the rain or in winter not only damages the health of workers, but also causes accidents such as slips and falls due to deterioration of the work environment.

Therefore, recently, a scaffold for an erection roof is erected so as to surround the entire structure or a part of the site to form a roof on the upper surface, and a sheet is stretched on the scaffold, and air is also provided on the upper surface of the scaffold for the roof. A temporary roof has been proposed in which an inflatable roof is placed to prevent rain and snow.

[0004]

However, the above-mentioned conventional type temporary roof has the following problems, and improvement has been desired. That is, in a building construction site or a housing construction site in an urban area, since the site site is narrow and surrounded by adjacent structures, it is extremely difficult to form a scaffold for a roof so as to surround the site and attach a roof thereon.
In addition, the above-mentioned site has a narrow entrance road, and even if a scaffolding for roof is built, heavy equipment such as a large crane for transporting the roofing material on the scaffolding cannot enter, and the roofing material must be divided. It is necessary to carry it on the scaffolding, assemble the roof on the scaffolding, and perform dangerous height work. Further, although the air expansion type roof is lightweight, not only is the fixing method complicated, but it is also necessary to install air piping to maintain the expansion, which causes a problem of high cost.

The present invention has been made in order to eliminate the above-mentioned conventional problems, and an object thereof is to provide a temporary roof having a light weight and strength and a method for easily installing the temporary roof. To do.

[0006]

In order to achieve the above-mentioned object, the temporary roof of the present invention has a plurality of gable frames erected on parallel beam members and sheets are spread between adjacent frames. In the temporary roof, each of the gable-shaped frames is made of a hollow profiled material, and at least one end of the two side walls facing each other has roof members formed by butting together profiled materials having guide grooves that open toward the outside. A guide roller having a pillar vertically extending from both ends of the roof member and pivotally supported at a lower end of the pillar is placed on a rail laid on a girder member.

Further, in the construction method of the temporary roof, a guide rail is laid on the upper surface of the girder members arranged in parallel, the roof member and the pillar are provided from one end side of the guide rail, and the guide roller is provided at the lower end portion of the pillar. A plurality of supported gable frames are sequentially arranged and fixed in the same span, and a sheet is stretched between adjacent gable frames.

In the temporary roof of the present invention, the gabled frame, which is a main member, is formed of an aluminum mold material, so that the roof itself can be reduced in weight. In the temporary roof construction method of the present invention, the gable frames assembled on the ground in advance are sequentially pressed from one side of the guide rails on the girders arranged in parallel, fixed with the same span, and then the adjacent gable frames are fixed. Since the seats are spread on each side, it is easy to install a temporary roof in a narrow space.
