DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling temporary gate which is installed at an entrance of a civil engineering or construction site or the like and which opens and closes the entrance.

[0002]

2. Description of the Related Art At the site of civil engineering and construction work, etc., it is possible to prevent outsiders from entering the construction site without permission and causing accidents, and to prevent earth and sand and construction materials during construction from scattering outside. For the purpose, an assembly type temporary fence or temporary gate is installed around the construction site. For example, FIG.
Shows an example of a conventional temporary gate installed at the entrance of a construction site. The temporary gate 80 is the same as a first pipe group 82 composed of a number of iron pipes 82a extending vertically. It comprises a second pipe group 84 composed of a number of iron pipes 84a extending in the up-down direction. Each of the pipe groups 82, 84 is rotatably connected in a so-called "pantograph" shape. Then, for example, the temporary gate 8
In a state where the fixed support 86 disposed at the left end of the gate 80 is fixed to the left end of the entrance, the movable support 88 disposed at the right end of the gate 80 is moved to the left to shorten the temporary gate 80. The entrance can be closed by moving the movable support 88 to the right and extending the temporary gate 80.

[0003]

SUMMARY OF THE INVENTION The above-mentioned temporary gate 8
Numeral 0 is configured as a completed product whose maximum length when extended is standardized to 2 m, 3 m, or the like, and does not have a structure in which a plurality of these temporary gates 80 can be connected in series.
Therefore, the entrance provided at each site can only be set to an opening width corresponding to the maximum length of the temporary gate 80 when it is extended, which sometimes hinders the loading of materials. Also,
For example, a temporary gate 8 designed to have a maximum length of 3 m when extended.
In the case of No. 0, since its weight is 60 kg or more, there is a problem that it requires mechanical force for handling such as movement and installation, and the installation work at the construction site is troublesome. Further, it is pointed out that a smooth opening / closing operation cannot be performed because of its heavy weight, and that it has a low rigidity in the front-rear direction and is easily twisted or fall down.

As described above, since a large number of iron pipes 82a and 84a are connected, when the pipes 82a and 84a are extended to close the entrance and exit, each of the pipes 82a and 84a is closed.
Even if a gap is formed between 84a and a problem arises in the shielding property and an outsider can be prevented from entering the construction site, it is possible to prevent earth and sand and construction materials during construction from scattering to the outside. There was a problem that could not be obtained.
