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. In other words, if the sky above the building can be covered with a temporary roof, the construction work can be carried out under that, so that the work process can be easily secured, the working environment is improved, and the quality of the building is improved. It is possible to improve.

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 constructed in which a temporary column is built on the outer periphery of a building, and a temporary roof that can cover almost half of the building is lifted up along the temporary column. Things have come to be used. This temporary structure is an integrated system for ground and underground construction, and has a wide ceiling opening, so it is excellent in workability such as handling of equipment and materials at a construction site.

[0005]

However, since the temporary roof of the temporary structure cannot cover the entire building, it is not a perfect weatherproof type. The present invention is intended to solve the above problems, and its purpose is to:
It is intended to provide an all-weather temporary roof with improved workability on a construction site.

[0006]

In order to achieve the above object, an all-weather temporary roof according to the present invention supports a temporary roof part which can be horizontally expanded and contracted and moved by a temporary pillar, and is lifted and lowered. The problem is solved by making it possible. The temporary column may be an assembled framed column with an elevating device or a self-elevated column.

Further, the support pillar for supporting the temporary roof portion and the support pillar for mounting the elevating device may be provided separately.

EXAMPLE A preferred example of an all-weather temporary roof according to the present invention will be described below with reference to the case where the temporary roof is used in the building process of a building. FIG. 1 is a perspective view of a temporary roof, and FIG. 2 is a schematic sectional view thereof. 1 and 2 show the construction process of the third floor portion of the building 1, which will be sequentially described below from the beginning.

1st step Construction of frame support pillars, installation of lifting device At the time of underground construction (mounting work), a concrete foundation 3 for placing the frame support pillars 2 is placed outside the excavation area. Further, the frame support 2, the external scaffold 4, and the lifting device 5 described later are assembled on the ground. The structure of the stanchion 2 is that it has the strength to support the temporary roof, and
This was to facilitate dismantling, and at the same time, it was possible for workers to pass through. After the frame columns 2 are built in the girder direction of the building 1 at appropriate intervals, an appropriate external scaffold 4 is installed between the columns 2 and 2.

As shown in FIG. 3, a lifting device 5 is attached to the frame support 2. An upper lifting frame 15 and a lower lifting frame 15 'are attached to the upper and lower portions of the frame support 2 via a plurality of guide rollers 16 so as to be able to move up and down. A hydraulic cylinder 18 is provided between the frames 15 and 15 '.
The rail receiver 17 on which the garter rail 7 is placed is fixed to the side surface of the upper lifting frame 15 with the interposition of.

Second Step Formation of Temporary Roof Next, the structure of the roof portion 9 will be described with reference to FIG. Figure 4
(1) is a plan view of the roof portion 9 installed on the pair of garter rails 7. The roof frames 6 and 6 are arranged so as to be orthogonal to the garter rails 7, and the wires 10, 10, and 10 are provided between the roof frames 6 and 6 in parallel with the garter rails 7.
The sheet material 8 is hung on the wire 10 to form the roof portion 9. The sheet material 8 is preferably a translucent film material in order to ensure a comfortable working environment. Further, the eaves of the roof frame 6 is preferably stretchable. All the work described so far can be done on the ground.

By horizontally moving the roof frame 6 on the garter rail 7, the roof 9 can be opened and closed with respect to the work site below. In addition, the wire 1 is wound by the wire winder 11 provided in the roof frame 6.
The sheet material 8 can be expanded and contracted in the axial direction of the garter rail 7 by expanding and contracting 0 so that the sheet material 8 can be expanded and folded. Expansion of sheet material 8
Even if the reduction is not performed by the wire 10 and the wire winder 11, a bellows type (accordion type) frame (not shown) may be bridged between the roof frames 6, 6. Further, a steel pipe may be used instead of the wire 10, and the sheet material 8 may be suspended on the steel pipe. If this steel pipe is accommodated in a sheath pipe (not shown) having a larger diameter than the steel pipe provided in the frame 6, the sheet material 8 can be smoothly folded.

The span length and the number of spans of the roof portion 9 are
Appropriate size and number are selected according to the size of the building 1.
If the specifications are unified, it can be diverted to other sites. In this way, when it rains, various works are done while covering the upper part of the site. In addition to opening and closing depending on weather conditions, the roof 9 is opened and closed freely when securing a place for loading and unloading of materials and the like by a crane and selecting a handling place. In FIG.
A movable roof frame 6 ′ equipped with an overhead crane 14 movable in the span direction is arranged between the roof frames 6 and 6 to facilitate the on-site handling work. It can be omitted depending on the situation of the site.

FIG. 5 is a plan view showing a fixed roof portion 9 ', in which openings are partially provided except for the beams and columns of the plan plan. Compared with the movable roof part 9, the size and position of the opening are slightly limited, but there is an advantage that the structure is simple.

After the completion of the third step excavation work and the underground skeleton work, the first-floor skeleton work is performed, and after the first-floor skeleton work is completed, the frame support 2 and the external scaffold 4 are assembled to a predetermined height. After that, the hydraulic cylinder 18 of the lifting device 5 is driven to lift up the roof 9 to a desired height.

After the fourth step , the third step (assembly of the frame support 2 → assembly of the external scaffold 4 → liftup of the roof 9) is repeated,
Build up to the top floor.

In the above-described embodiment, the lifting device 5 is attached to the assembled frame strut 2 to lift up the roof portion 9, but this may be replaced with a self-climbing strut (self-elevating strut). it can. That is, although FIG. 6 shows a state in which the self-climbing pillar 2a is slightly elevated from the ground, the legs of the self-climbing pillar 2a are fixed to the body of the building 1 by the anchors 2b, and the roof is fixed by the pillar 2a. The part 9 may be lifted up. In this case, as the external scaffold 4, it is preferable to connect the self-climbing columns 2a, 2a with a scaffold plate (not shown).

Further, in the embodiment shown in FIGS. 1 and 2, at the same time as supporting the roof portion 9 by the frame support 2,
The roof part 9 together with the garter rail 7 was lifted up all at once by the lifting device 5 attached to the support column 2. However, at the time of lifting up, it is necessary to temporarily suspend field work in consideration of safety. In the embodiment shown in FIG. 7, a pillar 2c for supporting the garter rail 7 and the roof 9 and a lifting device 5 are provided.
This is an example in which a column 2d for mounting the is separately provided.
For the purpose of convenient lifting work, two lifting columns 2d are erected at approximately the center of the building 1 in the girder direction using H-shaped steel and prisms, and are assembled into a framework so that they can pass from the external scaffold 4. The roof support columns 2c are also framed so that the garter rail 7 is supported at the top of the frame as shown in the cross-sectional view (FIG. 8). Both the roof pillar 2c and the lifting pillar 2d are of a stacking type and can be extended upward.

When the roof 9 is to be lifted up, as shown in FIG. 9, after assembling the lifting pillar 2d, the right roof pillar 2c and the outer scaffold 4 are assembled to a predetermined height, and the roof 9 is moved to the right. After that, the left roof pillar 2c and the outer scaffold 4 are assembled to the same height. Finally, the lifting column 2d
By stacking the outer scaffolds 4 in between, the garter rails 7 will be in the horizontal state similar to FIG. As the lifting device, besides the hydraulic cylinder 18, a two-point horizontal suspension chain block 20 that can be lifted while accurately maintaining the levelness can be used.

[0020]

In the all-weather temporary roof according to the present invention, since the temporary roof portion can be expanded and contracted in the horizontal direction and can be moved in the horizontal direction, the roof portion is large over the entire period of the construction work. An opening can be secured. Therefore, the position of the loading opening is not limited, and large equipment and materials can be easily loaded and unloaded when used in combination with an overhead crane.

Further, the temporary roof portion can be raised according to the progress of the construction, and the productivity and work efficiency at the construction site can be improved. Furthermore, by assembling structures such as temporary columns, scaffolds and temporary roofs on the ground, it is possible to reduce dangerous work at high places and ensure safety.
