Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather temporary roof used in construction sites such as construction and civil engineering.

[0002]

2. Description of the Related Art In recent years, in order to improve the working environment at construction sites such as construction (avoid rain or direct sunlight in summer), general contractor companies have been developing temporary weatherproof roofs. Known are all-weather temporary roof "Paragas", Asuka temporary roof "Kasataro", Shimizu construction "Nanpu", etc. These all-weather temporary roofs have rails laid on support members such as frame scaffolds or steel columns that surround the construction site, and a plurality of steel-framed frames that are shed structures are provided on the rails so that they can run. Moreover, the tent membrane is stretched over each frame in a bellows manner, and the roof can be opened and closed by appropriately traveling the frame.

[0003]

However, the conventional all-weather temporary roof has the following problems. Since the roof has a plurality of steel-framed frames (roofs) that can run on rails as a component, the weight of each member increases and the number of members increases, so that the frame, etc. can be carried in, assembled, and There is a problem that a lot of labor and time are required for installing a roof (installing the roof on a supporting member). For example, in the case of a Hazama-type all-weather temporary roof (applicable space: 18m opening x 60m depth) -Material loading: 10t truck x 10-Assembling days: 15 days (10 people x 15 days) are required. Moreover, since the weight of the temporary roof is large, a large crane is required for its installation and removal. For this reason, installation is not possible unless there is enough space to install a large crane beside the site. For example, in the case of the above-mentioned Hazama-type all-weather temporary roof: ・ Assembling and disassembling: 25t crane ・ Roof installing: 200t crane (when the roof is installed 25m above the ground) is required. Further, since the roof and rails are heavy, a supporting member that is strong in the vertical direction is required. On the other hand, when the roof is relocated, not only the roof but also the rails have to be relocated, so it takes a lot of time to relocate. In order to deal with this, there has been developed one that raises the roof together with the rail at a stretch, but at this stage, the cost is very high and it is not practical. Further, the conventional all-weather temporary roof described above requires enormous costs for assembling, installing, removing, and reshuffling, so that it is practically impossible to employ it in small and medium-sized sites. Therefore, the present invention can reduce the number of members and bring in, assemble, and dismantle members with a small amount of work and cost, while not requiring a large lifting machine for roof installation and rearrangement and can be done in a short time. The purpose is to provide an all-weather temporary roof.

[0004]

A girder-side scaffold in the scaffold and a girder-side end of the tent membrane are connected to each other. The second all-weather temporary roof is
It is characterized in that it is provided with a drain metal article which is detachably attached to a required part of the tent membrane and a drain hose connected to the drain metal article. The third all-weather temporary roof is the first or second one, wherein the winding rod of the winding device is
It is characterized in that a plurality of rod members having a required length that can be connected to each other are connected to each other. The fourth all-weather temporary roof is characterized in that in the third one, the required bars are expandable. The fifth all-weather temporary roof is the first, second, third or fourth one, wherein the winding device is
It is characterized in that it can be moved in the column direction and / or the beam direction. The sixth all-weather temporary roof is the first, second, third, fourth or fifth one, wherein the winding device is
It is characterized by being able to move up and down.

[0005]
