DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary tent for construction used at a construction site such as a building, and more particularly to a temporary tent for opening and closing a roof surface of a tent for carrying in and out of materials. Involved in temporary tents.

2. Description of the Related Art As is well known, most civil engineering and construction works are carried out outdoors, so they are easily affected by natural conditions such as wind, rain and snowfall. As a result, there is a problem that the construction cost is increased due to a delay in the work process or a decrease in the operation rate. In addition, outdoor work, which is easily affected by natural conditions as described above, not only impairs the health of workers, but also tends to cause personal injury such as slipping and falling due to deterioration of the work environment, while the quality of concrete and steel frame welding deteriorates. It is also a cause.

In recent years, for the purpose of improving the working environment as described above, a temporary tent or a temporary roof device having a structure capable of covering the whole or a part of the construction site has been developed, and a part thereof has already been put into practical use. Has been provided. In other words, in order to enable on-site work even during rainfall and to allow normal construction work using heavy equipment to proceed under the roof, external scaffolds at the construction work site, lifting masts, etc. Attempts have been made to mount or disassemble temporary tents and roof devices on the top surface to protect or block construction sites from the elements.

[0004]

The present invention relates to a temporary tent which has been developed for the same purpose as described above. The present invention proposes a temporary tent having an opening / closing mechanism that can be opened and closed entirely. That is, once this type of tent is installed, it becomes a hindrance when carrying in materials from outside. Therefore, the conventional fixed tent is mounted on a scaffold, and the roof surface of the tent is manually opened to carry in materials. However, on construction sites where there is not enough room, it may not be possible to set up scaffolds as desired. That is, in recent years, it is often the case that buildings are built to fill the entire site due to difficulty in obtaining land, and therefore, it is sometimes impossible to build a scaffold around the tent so that a person can ride and open and close the tent.
In the temporary tents described above, as the height of the building gradually increases as the construction progresses, the installation position of the temporary tents needs to be raised accordingly,
Sometimes it has to be installed at a height higher than 0 m. In such a case, it must be avoided that a person gets on a high scaffold and opens and closes the seat manually with respect to safety.

[0005]

Means for Solving the Problems Here, the present invention provides:
A unitary mountain-shaped frame member consisting of a roof member and strut members fixed to both ends thereof is juxtaposed so as to face each other,
A flexible tent for covering the roof surface in a temporary tent in which a roof surface of a unit that is assembled in a shed by passing a purlin and / or braces between the opposed frame members is covered with a flexible sheet material. The sheet material is supported so as to be slidable along a concave groove formed in the roof member, and tension bars are fixed to both ends of the sheet material, and a winding wire connected to a winch is stretched to the tension bar. Then, the flexible sheet material for covering the roof surface is slid along a groove formed in the roof member while the sheet material is extended by driving the winch, so that the roof surface can be opened and closed. Even if the site does not have enough room and the scaffolding cannot be set up as desired, the roof of the tent can be opened or closed partially or completely for carrying in materials. Than it is.

As described above, in the present invention, the flexible sheet material for covering the roof surface is slid along the roof member while the sheet material is extended by driving the winch to open and close the roof surface. Therefore, there is no need to wrap or fold the sheet material when storing the sheet material, so that the sheet material can be easily constructed and requires no storage space.

In a preferred embodiment of the present invention, a flexible sheet material for covering the roof surface of the gable-shaped unit is provided with a fixed sheet material stretched so as not to move halfway with respect to the half surface of the roof. One end of the fixed sheet material is provided at one end of the movable sheet material in the vicinity of the ridge purlin of the unit in which the shed is assembled, the movable sheet material being constituted by a movable sheet material that can open and close the half surface of the roof. Due to the overlap (polymerization), the abutting portion of the fixed sheet material and the movable sheet material has a good weathering action, that is, good sealing performance. Further, in this embodiment, since only the movable sheet material is pulled by the winch to open and close only the half surface of the roof, there is an advantage that the power required for opening and closing is small.

[0020]

As described above in detail, in the temporary tent to which the present invention is applied, it is necessary to open and close the roof of the tent in order to carry in materials to the site. Conventional tents are installed on a scaffold and the roof sheet is opened manually to carry in materials. However, on construction sites where there is not enough room, external scaffolds cannot be installed as desired. Also, with this type of temporary tent, as the height of the building gradually increases as the construction progresses, it is necessary to raise the installation position of the temporary tent, and at least 20 m above the ground
It must be installed at a higher position. In such a case, from the viewpoint of safety, it is necessary to prevent a person from riding on the roof and manually opening and closing the seat. However, the temporary tent of the present invention supports a flexible sheet material for covering a roof surface so as to be slidable along a groove formed in a roof member, and fixes tension bars to both ends of the sheet material, respectively. And a pulley attached to the tension bar? A wrapping wire connected to the winch is stretched through, and the flexible sheet material for covering the roof surface is inserted into a groove formed in the roof member while the sheet material is extended by driving the winch. By sliding along the roof, the roof surface can be opened and closed, so that even if you cannot install an external scaffold as you would like because there is no room on the site, you can safely open and close the tent roof surface for carrying in materials etc. It is effective.
