Description

{Prefabricated Work Structure with Multi-Function}

The present invention relates to a multifunctional assembly type workbench, and more particularly, to a multifunctional prefabricated workbench, which can be easily assembled by assembling a plurality of workpieces in height and lateral direction during construction of various kinds of structures, thereby effectively storing and using workpieces.

Generally, when constructing various buildings, various temporary scaffolds (so-called bits) are installed for safety during work. Workers are provided with footsteps for traffic and safety nets to prevent falling objects.

In such a construction site, when a worker approaches to a high place and performs work or inspection, the worker must approach using a temporary construction, which is often dangerous and difficult to access.

Accordingly, conventionally, a workbench having a predetermined height is provided at a desired position, and the workbench is lifted up to the workbench provided by the worker. In the conventional workbench, as the work height changes, There is a limit according to the working conditions. In case of manufacturing the work table at a high level, there is a possibility that the worker may fall off from the high work table due to a safety problem during the work at the upper end of the work table.

In addition, the conventional worktable has a disadvantage in that it is not easy to move and store because the structure is fixed and has a large volume.

Also, between the support posts 71 on both sides, the reinforcing member 74 can be connected across the reinforcement member 74 as a rigid structure.

The support structure 70 can be placed on the upper part of the work structure 1, and a worker can use the work structure as a path by placing a foot plate or the like.

As shown in FIG. 2, the working structure 1 is preferably formed such that the length of the connecting frame 20 is longer than the length of the connecting frame 30 so as to be rectangular when viewed in plan view.

In this case, as shown in FIG. 8, when the work structure 1 is folded, the folding range is set to be a rectangular shape, Can be reduced compared to when.

Further, as shown in Fig. 7, a protective net member 80 may be provided on each side surface of the work structure 1. As shown in Fig. The protection net member 80 includes a net 81 having a predetermined area and a substantially rectangular shape and a connection clip 82 at both ends of the upper end of the net 81, And the connection frame 30 is formed on the upper surface of the frame 30.

When the protective net member 80 is assembled to the side surface of the working structure 1, it can be fitted on the outside and inside.

In other words, at the position where the ladder portion 34 of the working structure 1 is formed, the protection net member 80 is fitted in from the inside so that the worker can ride the ladder portion 34, have.

The connection clip 82 is bent to be substantially circular and connected to the upper connection frame 21 located at the upper part while forming the connection frame 30 and then fastened to a pair of ends of the connection clip 82 83) to be fixed.

A hook member 84 may be formed on the lower portion of the protective net member 80 to detachably connect to the lower connecting frame 32 located below the connecting frame 30.

10, the working structure 1 can be assembled by extending in the lateral direction, and the supporting structure 70 can be used to connect between the working structure 1 and the working structure 1, (1) can be increased as needed.

10, the protection net member 80 may be assembled to the front surface of the work structure 1 to serve as a safety net.

That is, the support structure 70 also serves to connect the work structure 1 and the work structure 1, and at the same time, it is possible to assemble the protection network member 80 over all the front surfaces of the work structures 1, It can be used as a multi-function.

The support structure 70 connected between the work structure 1 and the work structure 1 is connected to the support structure 70 formed on the work structure 1 so as to have a larger width than the support structure 70, 80 may be arranged so as to be aligned in a line.

According to an embodiment of the present invention, for example, a work structure 1 may be provided at a building construction site, and an operator may perform various operations by climbing the work structure. First, , Folded and laid up through the posts 10, 11, 12 and 13 as shown in Fig.

The working structure 1 is configured such that the four posts 10, 11, 12 and 13 are connected by the connecting frames 20 and 30 to form a rectangular shape. As shown in FIG. 2, The connection frame 20 and the connection frame 30 may be connected to each other in the same direction symmetrically with respect to the diagonal direction with the connection frame 30 arranged in a direction orthogonal to the one connection frame 20, When the post 11 and the post 12 are pushed diagonally inward as a connecting body, a connecting frame 30 constituting one (left side) connecting body is welded and fixed between the post 10 and the post 12 Therefore, when the post 12 is pushed diagonally inward, the post 10 also rotates itself.

Then, the connecting frame 20 connected between the post 12 and the post 13 is expanded while the post 13 is moved in the rightward direction, thereby moving the post 12 in the diagonal center direction.

At this time, the upper connection frame 22 and the lower connection frame 22a constituting the connection frame 20 connected between the posts 12 and the posts 13 are welded to the connection rings 41 and 43, The connecting rings 41 and 43 are rotatably coupled on the outer circumferential surface of the posts 12 and 13 so that the upper connecting frame 22 and the lower connecting frame 22, (22a) can be rotated simultaneously as the connecting rings (41) and (43) are rotated.
