Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple work room used for telephone line connection work, construction sites, etc.

0002

[Prior Art] A typical example of manhole construction is telephone line connection construction, in which it is decided whether or not to proceed with the work based on the weather and construction progress the day before the construction day or early on the day of the construction, and then the work is carried out. In case of construction, the truck is usually equipped with equipment such as construction signs, generators, pumps, ventilation fans, etc.
Workers travel to the construction site in van-type freight cars. At the site, we first install safety cones, sign boards, etc. around the manhole on the road to display to passersby and vehicles that the manhole is under construction to ensure safety, and then close the manhole cover. Open the manhole and then install a manhole frame around the manhole to prevent dirt, dust, rainwater, etc. from entering the manhole from entering the manhole. Next, as a safety check inside the manhole, we measure toxic gas and oxygen concentration, and check the water in the room.Furthermore, we install lighting equipment in the room, remove water with a pump if there is water in the room, and use a ventilation fan. Bring in fresh outside air. After safety checks and work preparations are completed in this way, the telephone line connection work is carried out.

[0003] By the way, this series of work is carried out on the road because manholes are installed on the road, but there is usually no shield to cover the top of the work site on the road. For this reason, construction work has to be carried out in the open, which is directly affected by the weather, making it difficult to schedule work as work cannot be done during bad weather such as rain, and being directly exposed to dirt, dust, etc. The working environment was not very good.

On the other hand, as a prefabricated folding house used as a temporary office or warehouse at a construction site, etc., in order to facilitate transportation, storage, etc., the component parts of the prefabricated building, such as floor panels, wall panels, Conventionally, roof panels etc. are connected and made into a foldable form, for example, Japanese Patent Application Laid-Open No. 61-211431 and Japanese Patent Application Laid-open No. 61-1.
There are publications such as No. 72941. Of these, JP-A-61
-211431 publication has a floor panel and a roof panel that can be folded into two between two opposing wall panels, and the other wall panel is horizontally rotatably connected to the wall panel. To assemble the house, hook the hook of a crane onto the ridge hanging bracket fixed to the folding part of the roof panel and lift the folded roof panel and The floor panels are opened by their own weight, and the wall panels that are folded inward are opened to both sides by hand.

[0005] Furthermore, in the device disclosed in JP-A No. 61-172941, the lower edge of the end wall is rotatably attached to the side edge of the floor panel, and the upper end of the end wall is connected to and detached from the roof panel via a link. The girder wall is composed of an upper wall and a lower wall, the lower edge of the lower wall is rotatably connected to the side edge of the floor panel, and the upper girder wall is rotatably connected to overlap the lower wall. connect walls,
The upper edge of the upper wall abuts against the roof panel when assembled. To assemble the house, the roof panels are hoisted up by a crane, and the gable walls are erected by their own weight via links, and the girder walls are manually erected from the floor panels to the roof panels. increase.

[0006]

However, since a work room for manhole construction is frequently moved, it is required to be easy to transport and install. When assembling a house with the conventional methods mentioned above,
It is necessary to lift the roof panels with a crane, which not only requires the preparation of a separate crane or other work vehicle, but also requires large-scale assembly work. In addition, the assembly cannot be completed simply by lifting the roof panels with a crane; some wall panels must be assembled by hand, which requires manpower and labor, and is difficult to assemble. Not efficient. In addition, there is a drawer-type house that can be assembled with one touch, and this is stored nested inside the inner box unit inside the outer box unit.
At the site, the inner box unit is pulled out from inside the outer box unit, and the inner box unit is connected to the outer box unit, and both units form a house, but this pull-out type cannot be folded, so it is difficult to transport. A large amount of space is required for storage, and the advantages of the folding method are lost.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the disadvantages of the conventional example and to provide a simple working room that can be easily folded and assembled by only one worker and has good installation workability.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a box-type simple working room consisting of front, rear, left and right side wall panels, and a ceiling panel supported by the upper part of the side wall panels. has its side edges pivoted to the side edges of the front and rear side wall panels, and is foldable inward at the center, and is provided with channel-shaped rails cut at the folding points on the outside of the upper ends of the left and right side wall panels, The end of the rail is cut at the pivot point and extends to the front and rear side wall panels, one end of the rail is closed to serve as a stopper, and the other end is directed downward; Wheels for sliding on the rails are provided on the front end side of the ceiling panel via a downward bracket, casters are provided on the lower end of the side wall panel, and a support base is provided below the side wall panel to protrude inwardly, The gist of the present invention is to removably place a floorboard panel on this support base, and to provide a skirt portion for a windshield below the side wall panel.

[0009]

According to the present invention as set forth in claims 1 and 2, the left and right side wall panels are folded inward at the center, and the ceiling panel is stacked on top of the other to make the whole flat and transported to the site. At the site, the work room is assembled by stretching the folded left and right side wall panels and closing them off by sliding ceiling panels over the upper, lower, left and right side wall panels that make up the rectangular space. If installed so that it is covered, manhole construction can be carried out within this work room.

According to the third aspect of the present invention, in addition to the above effect, it is possible to prevent wind from flowing in from below each side wall panel.
