Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a scaffold constructed around the outside of a building in order to work on the outer wall of a building at a construction site.

[Conventional technology]

Traditional frame scaffolding is fixed, with the lower part fixed on the ground and the upper part built up to the height of the building.
Scaffolding had to be constructed around the entire perimeter of the building.

[The problem that the idea attempts to solve]

In construction work, when installing sashes on the outside of a building, painting beams, painting the outer wall rim, and other external wall work, it is necessary to construct a frame scaffold, but conventional frame scaffolding is required. Since the building cannot be moved, scaffolding had to be constructed around the entire perimeter of the building. Therefore, it took a great deal of money and time to construct the scaffolding.

Therefore, the present invention provides a simple scaffold that can be moved to any required location without requiring scaffolding to be constructed around the entire building.

[Means to solve the problem]

In order to achieve the above object, the simple scaffolding of the present invention includes support rollers that move on the upper surface of the rim to support the vertical tubes, and support rollers that move on the upper surface of the rim to support the vertical tubes, and support rollers that move on the upper surface of the rim and support the vertical tubes, respectively, on the upper and lower parts of the vertical tubes that are arranged in parallel. Supporting rollers are provided facing rearward, and an auxiliary pipe is provided at the top of the vertical pipe, and a scaffolding bracket is provided at the bottom of the vertical pipe, projecting forward. A handrail post is provided in the handrail post, a connecting pipe is provided between adjacent handrail posts to connect the vertical pipe in the horizontal direction, and a scaffold board is installed between adjacent scaffolding brackets.

[Effect]

Next, to explain the function of the present invention based on the drawings, the scaffold of the present invention is constructed by connecting two or more vertical pipes 1 in the horizontal direction, but the required number can be adjusted depending on the size of the construction site. The support roller 3 of the scaffold of the present invention, which is connected to the vertical tube 1, is placed on the rim 2 of the required height, and the support roller 4, which is attached close to the bottom of the support roller 3, is placed with the opening downward. If the scaffold of the present invention is inserted through the side opening of the rim 2 with a square cross section attached to the pillar 17 facing toward the side, the scaffold 2 of the present invention will not come off because the rim 2 is held between the supporting rollers 3 and 4.

Then, by passing the scaffolding board 13 between the scaffolding brackets 8, a scaffolding is constructed.

Therefore, when the worker pushes and pulls the handrail post 11 or the vertical pipe 1 left and right, the scaffold moves easily left and right by the support rollers 3 and 4, so that the scaffold follows the movement of the construction site sequentially. Is possible.

In addition, the scaffold of the present invention not only connects the vertical pipes 1 in the horizontal direction, but also connects the vertical pipes 1 in the vertical direction.
It is also possible to increase the number of footholds by connecting the vertical pipes 1 to 4, and in this case, supporting rollers 3 and 4 may be attached to the vicinity of the center of the vertical pipe 1 (as shown in FIG. 2).

〔Example〕

Hereinafter, an embodiment of the simple scaffolding of the present invention will be explained based on the drawings. In Figs.
A support roller 3 that rotates in the vertical direction so as to move along the horizontal plane of the rim 2 having a cross-sectional shape attached to the support roller 3
Further, disc-shaped support rollers 4 that rotate in the horizontal direction so as to engage and move inside the trunk rim 2 are attached by clamps 6 to the building side by armrests 5, respectively.

Support rollers 3 are attached to at least the top and bottom of the vertical tube 1, and a support roller 4 is attached to the bottom close to the support rollers 3. It is desirable to connect it to the vertical tube 1 by.

8 is a scaffolding bracket attached to the vertical pipe 1 by a bracket clamp 9 fixed at the base facing the outside of the building, and a handrail post 11 is attached to the bracket clamp 10 fixed to the tip of the scaffolding bracket 8 in parallel with the vertical pipe 1. is installed.

12 is a connecting pipe for connecting the vertical pipes 1 in the horizontal direction, and is connected to adjacent handrail posts 11 with clamps 6.

13 is a scaffolding board placed between 8 scaffolding brackets,
14 is a connecting pipe provided with a pin hole 15 for connecting the vertical pipe 1 in the vertical direction, and is connected to the pin hole 18 at the end of the vertical pipe 1 with a pin 19.

Reference numeral 16 denotes an auxiliary pipe that connects the vertical pipe 1 and the handrail post 11, and is attached to the vertical pipe 1 at one end and the handrail post 11 at the other end with a clamp 6, respectively.

In addition, 17 in the figure is a pillar to which the furring 2 is attached.

Moreover, FIG. 3 shows another embodiment, in which the rim 2
If the support roller 4 is square tubular, it is impossible to engage the support roller 4 inwardly, so by deeply sandwiching the front and back of the rim 2 with the vertically long support rollers 4, the scaffolding can be secured between the support roller 3 and the support roller. 4, it will not come off.

[Effect of idea]

According to the present invention, since the scaffold is movable,
There is no need to construct it around the entire building as in the past, and the scaffolding only needs to be moved as the construction site moves.

Furthermore, it is possible to increase or decrease the number of scaffolds in the horizontal or vertical direction depending on the number of workers and the area of the work site, so there is no waste.

Furthermore, the scaffolding of the present invention can be easily erected, resulting in low costs, and it also has the effect of shortening the construction period, since it does not take many days to erect the scaffolding as in the case of conventional scaffolding.

Claims (1)

[Scope of utility model registration request] A support roller 3 that moves on the upper surface of the rim 2 to support the vertical tube 1 and a support roller that engages inside the rim 2 and supports the vertical tube 1 are provided at the upper and lower parts of the vertical tubes 1 and 1 arranged in parallel, respectively. At the same time, an auxiliary pipe 16 is provided on the upper part of the vertical pipe 1, and a scaffolding bracket 8 is provided on the lower part of the vertical pipe 1, respectively, protruding toward the front.
