[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather temporary structure.

[0002]

2. Description of the Related Art At a construction site, various inconveniences may occur if construction such as excavation, concrete pouring, gas pressure welding of reinforcing bars, marking out, plastering, etc. is carried out in the rain or in strong wind.
An all-weather construction system is desired. That is, if the upper part and the side part of the building can be surrounded by the temporary structure, the construction work can be carried out in the temporary structure, so that the work process can be easily secured and the work environment can be improved, and , The quality of buildings can be improved.

The conventional all-weather construction system is for exclusive use in underground construction or above-ground construction, and is not a consistent system. When constructing the entire construction construction in all-weather construction, a plurality of different construction systems are used. Had to adopt. Therefore, assembling each temporary structure,
The dismantling work required extra personnel and days.

Also, most recently, a temporary structure has been used in which a temporary pillar is built around the outer periphery of a building and a temporary roof covering almost half of the building is lifted up along the temporary pillar. It has come to be.

[0005]

However, although the above-mentioned temporary structure is an integrated system for ground and underground construction, it is not completely weatherproof and the lift-up mechanism is complicated, so it is not always satisfactory. It was
The present invention is intended to solve the above problems, and an object thereof is to construct an all-weather temporary structure with a simple structure and mechanism.

[0006]

In order to achieve the above object, an all-weather temporary structure according to the present invention has a structure in which a temporary beam is laid horizontally between opposing temporary columns, and The problem is solved by mounting a temporary roof on the, and making the temporary columns expandable and contractable as a multi-tube structure.

Further, the all-weather temporary structure according to the present invention further solves the problem by installing a temporary scaffold on the outermost pipe of the temporary columns adjacent in the girder direction.

[0008]

[Operation] A temporary column having a multi-pipe structure is built and a temporary beam is fixed to the outermost pipe. A temporary roof will be installed on the temporary beam. After raising the entire temporary roof to a predetermined height, the underground construction and the construction work up to the constructable floor will be performed. Next, the second inner pipe from the inside of the temporary column is lifted up, the entire temporary roof is raised, and construction work up to the floors where construction is possible is performed sequentially. By repeating the lift-up of this temporary column, construction work will be carried out to the top floor.

EXAMPLES A preferred construction system using the all-weather temporary structure according to the present invention will be described below with reference to the construction procedure diagram shown in FIG. 1st step Construction of temporary columns and foundation of temporary beams [Fig. 1 (1)] Set footing 1 for temporary construction on the site, and footing 1
Fix the temporary column 2 to the anchor. The structure of the temporary column 2 is a rod antenna type in which a plurality of square or round steel pipes having substantially equal lengths and slightly different cross-sectional sizes are superposed, and the outermost pipe 3 of the temporary column 2 is A support member 4 for fixing a temporary beam 5, which will be described later, is provided on the outer peripheral surface.

After the temporary columns 2 have been built in, the columns of the adjacent temporary columns 2 and 2 are tightly connected to each other in the direction of the girders by a horizontal tie member, and at the same time the temporary beams 5 are connected.
Is assembled on the ground. The temporary beam 5 has a lattice structure made of steel pipe and is unitized with a length of about 3 m and assembled on site. By preparing the temporary beams 5 of various lengths in advance, it is possible to correspond to the size of the building.

Second Step Attachment of Temporary Beam and Temporary Scaffold [FIG. 1 (2)] The temporary beam 5 assembled to the base is fixed to the supporting members 4 and 4. After that, a roof material, a horizontal brace, etc. (not shown) are installed on the temporary beam 5, and a ceiling sheet is stretched on the roof material and the horizontal brace. The ceiling sheet is preferably a translucent film material to ensure a comfortable working environment. Moreover, you may set a sheet | seat also on a wall surface as needed. A hoist rail 6 and a hoist 7 are installed under the temporary beam 5 for use in carrying in and moving building materials. Further, a temporary scaffold 8 is provided between the temporary columns 2 and 2 that are adjacent to each other in the column direction.
The scaffold 8 is attached to the outermost pipes 3 and 3 of the temporary columns 2 and 2, as shown in FIG. 2B showing the final stage of the construction procedure. All operations in this process can be performed on the ground.

Third step Lift-up of temporary beams [Fig. 1
(3)] The supporting members 4 and 4 are lifted up by an appropriate means such as a hydraulic jack type, a rack and pinion gear type, or a wire type to raise the entire temporary roof to a desired height. When the support members 4 and 4 are lifted up to a predetermined height, the support members 4 and 4 are fixed to the outermost pipes 3 and 3 of the temporary columns 2 and 2 with bolts or the like, and pinned to prevent the support members 4 and 4 from falling.
A brace is provided in the column direction of the adjacent temporary columns 2 and 2. After the temporary roof has been raised to a predetermined height as described above, underground construction and construction work up to a floor where construction is possible are performed.

Fourth step Lift up of the temporary roof [Fig. 1
(4)] By lifting up the second inner pipe (second inner pipe) from the inside of the temporary columns 2 and 2, the entire temporary roof is raised. FIG. 3 (1) shows an example of a wire-type lift-up mechanism. In the figure, reference numeral 10 is a wire, and reference numeral 11
Is a winch. FIG. 3B is a sectional view taken along the line II-II of FIG. 3A in the state before the lift-up.
After the lift-up, the second inner tube is fixed and the fall prevention measures are taken in the same manner as the third step. It is preferable to secure the stability of the temporary structure by tightly connecting the innermost inner pipes (innermost pipes) of the temporary columns 2 and 2 to the skeleton of the building with the connecting material 9.

Fifth step construction work [Fig. 1 (5)] Construction work is sequentially performed up to the floors where construction is possible.

6th process Lift-up, construction work [Fig. 1
(6)] The fourth and fifth steps are repeated to build up to the top floor.
FIG. 2 shows this state, in which FIG. 1A is a plan view, FIG. 2B is a front view, and FIG. 3C is a side view. It is preferable that the temporary roof has a span larger than that of the building by about 1 span, and the space 12 formed thereby is used for loading work or the like.

Next, a procedure for disassembling the all-weather temporary structure assembled as described above will be described. After the construction work is completed, if the tower crane or the like can be accessed from both sides of the structure when dismantling the temporary structure, the temporary pillar 2 and the temporary beam 5 can be hung by the crane.
On the other hand, when the installation location of the tower crane or the like can be secured only on one side of the structure, the tower crane (or truck crane) 12 is used to install the aerial work vehicle 13 and the mini crane 14 as shown in FIG. The portion of the tower crane 12 that cannot be lifted up and lifted down on the rooftop may be lifted down in cooperation with the mini crane 14.
