DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable roof for a construction site, which is provided on a scaffold at a construction site to save rain.

[0002]

2. Description of the Related Art A conventional scaffold at a construction site is made of a small number of members such as an iron pipe, a catwalk, and a joint member so that an inventory space can be reduced and assembly and disassembly can be easily performed. In the case of rainy weather, the top of the assembled fixed scaffold was covered with a sheet, etc., so that the work was done in a hurry to overcome the rain.

[0003]

However, in the means for covering the sheet at the top of the fixed scaffold, since the sheet can only cover the upper part of the limited space, it is necessary to change the sheet cumbersomely. . For this reason, there are many construction sites that take a short break in outdoor work in case of rain even if there is a little urgent construction. Also, in the midsummer, construction was performed while receiving direct sunlight, which increased worker fatigue, which in turn led to a reduction in work efficiency.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by attaching a movable roof to a conventional fixed scaffold for a construction site. An iron pipe 2 provided at an upper end of a fixed scaffold 1 is provided. A pair of guide rails 5 provided in parallel to the longitudinal mounting direction of the catwalk 4 with respect to the upper end 3 of the
A guide member 6 slidable along the pair of guide rails 5, two or more guide members 6 for each guide rail 5, a roof structure 7 moved along the guide rails 5 integrally with the guide members 6, and a roof. It comprises a fixing member 12 for fixing the structure 7 to the guide rail 5. Also,
The cross section of the guide rail 5 opening upward is fixed to the C-shaped channel 9 and the bottom of the C-shaped channel 9 using the fastening member 10 which is fastened and positioned with respect to the upper end 3 of the iron pipe 2. Is also good. Alternatively, a flat plate 13 in which the guide member 6 is loosely fitted in parallel with the opening 11 along the longitudinal direction of the C-shaped channel 9 may be used. Further, the fixing member 12 is loosely fitted into the C-shaped channel 9, and the flat plate 13 is provided with an opening 11 above the C-shaped channel 9.
It is also good that the flat plate 13 is screwed from the side so that the flat plate 13 can be pressed against the upper inner surface 14 of the C-shaped channel 9.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of mounting a movable roof for a construction site according to the present invention.

[0005] The fixed scaffold 1 is made of iron pipe 2 and braces 16,
The catwalk 4 and the like are combined according to each site so that work at high places can be performed safely. At present, it can be seen at any construction site. Looking at the vertical bar of the fixed scaffold 1, the iron pipe 2 is the mainstream. The catwalk 4 serves as a work passage and a work scaffold while increasing the structural strength of the fixed scaffold 1. The clamp 16 prevents the fixed scaffold 1 from twisting and tilting.

The guide rail 5 regulates the moving direction of the roof structure 7 and is fixed at an arbitrary position. The guide rail 5 is fixed to a vertical bar made of the iron pipe 2 of the fixed scaffold 1 via a fastening member 10. The fastening member 10 is welded or screwed to the lower side of the guide rail 5.

[0007] As shown in FIG.
The use of the mold channel 9 increases the degree of freedom in dealing with construction sites that are used in a rough manner. That is, the C-shaped channel 9 has a light weight and high strength due to its shape, and the attachment position of the fastening member 10 is on the opposite surface of the opening 11, so that welding and screwing can be easily performed.

When the C-shaped channel 9 is used for the guide rail 5, an inexpensive flat plate 13 as the guide member 6 can be loosely fitted in parallel with the opening 11 along the longitudinal direction of the C-shaped channel 9. It can be processed, and it can cope with some deformation.

[0009]

The roof structure 7 is integrally joined to the guide member 6 through a joint member 19 made of a screw or a pipe or the like which is vertically erected on the guide member 6.
It is also possible to combine the iron pipes 2 for assembling the fixed scaffolds 1, put the catwalk 4 on the upper part, and cover the sheet 22 with the catwalk 4 to save rain.

As shown in FIG. 4, it is convenient to make the asymmetrical roof structure 7 a ready-made product so that it can be connected to the joint member 19 on site. The roof structure 7 shown in FIG. 4 is formed by bending and welding an iron pipe or the like, and is configured to be divided into several parts. Symbol 21
Is used to cover the eaves during outdoor wall work so that rain does not fall on hand or adjust the blowing of wind.
Removal is also possible.

The fixing member 12 is a member for fixing the roof structure 7 to the guide rail 5 at an arbitrary position. The fixing member 12 prevents the roof structure 7 from moving during work due to wind or the like. It is also effective to fix the guide member 6 integrally joined to the roof structure 7 to the guide rail with the fixing member 12.

FIG. 5 is an embodiment of the fixing member 12, showing a state in which the fixing member 12 is provided on a flat plate 13. FIG. At the center of the flat plate 13, a joint member 19 for joining the roof structure 7 is planted. The fixing member 12 is provided adjacent to the joint member 19 in the longitudinal direction.

In FIG. 5, the fixing member 12 is a handle 2
It is constituted by a screw 24 with 3 and protrudes from the opening 11 above the guide rail 5 formed by the C-shaped channel 9 and is made operable. In the state shown in FIG. 5, the flat plate 13 is movable with respect to the bottom of the C-shaped channel 9. Here, the screw 24 serving as the fixing member 8 is attached to the handle 2.
When the screw 3 is tightened, the tip of the screw 24 hits the bottom of the C-shaped channel 9 and pushes up the flat plate 13. Furthermore, the screw 24
When the plate is tightened, the flat plate 13 becomes
5 is pressed. Here, the flat plate 13 serving as the guide member 6
Is pressed against and fixed to the inner surface of the C-shaped channel 9.

Further, it is also effective to provide the fixing member 12 at a portion of the roof structure 7 close to the guide rail 5 and to hold and press the guide rail.

[0016]

As described above, the movable roof for a construction site according to the present invention can be used outdoors without any trouble even in the case of strong rain in the middle of summer or direct sunlight. In addition, there is no need for expensive components to be newly added, and further, there is an effect that the structure has a structure that can withstand rough handling of on-site work. Further, by providing the fixing member 12, there is also an effect that the work can be performed with a sense of security without being moved by wind or the like.
