The present invention relates to a prefabricated scaffold for construction, and in particular, it can be easily assembled and disassembled in the field, so that the carrying and installation work can be easily performed, and the height of the scaffold can be freely extended to a desired length, and a remarkable work convenience can be exhibited. The present invention relates to a prefabricated scaffold for construction.

Scaffolding is a temporary product made by combining several long and short metal pipes so that workers can easily transport materials or perform maintenance, repair, and installation at the heights of construction sites. However, in general, a plurality of struts respectively placed at the four corners and a pair of struts of adjacent left and right sides, respectively, and a plurality of transverse supports horizontally arranged at equal intervals along the struts ( A ladder member), a plurality of cross reinforcing bars intersected by 'X' between each of the front and rear sides of each pair of struts, and a plurality of scaffold members fixed between a pair of transverse supports facing left and right sides. It is.

However, existing construction scaffolds have been constructed by welding each of the above metal tube members, or have a structure in which some of the members are prefabricated to facilitate carrying and installation operations to some extent. Even prefabricated scaffolds did not implement a structure that could easily assemble and disassemble all parts at the construction site, so there was a limit to efficiently carrying and installing.

In addition, these conventional prefabricated scaffolds are not only weak in strength, but also cannot extend the height of the scaffold to a desired length, and may not be easy in the case where the assembly is required to move to a desired position. In addition, there is a risk that the operator can not be provided with a stabilizer that can be firmly settled at any position, the operator can slip off or overturn the scaffold during operation on the scaffold.

In addition, in the upper structure of the scaffold, there is a problem in that there is no inconvenience for the operator to climb to the upper scaffold because the opening and closing device such as a door is not provided, there is also a problem that the work convenience.

The present invention has been made to solve the above-mentioned problems, the object is that all parts, such as scaffolding can be easily assembled and disassembled in the field, so that carrying and installation can be easily performed, scaffolding The height can be freely extended to the desired length, not only can be easily moved to the desired position even when the assembly is completed, but also can be stably settled in the position as well as the operator can easily enter into the upper fence member By providing a structure to provide a prefabricated scaffold for construction that can exhibit a significant work convenience compared to the prior art.

Building prefabricated scaffolding according to the present invention for achieving the above object is connected between a plurality of struts respectively placed in four corners, and a pair of struts respectively adjacent to the left and right sides and at equal intervals along the struts. A plurality of transverse supports fixed horizontally in a row, and the front and rear sides of each of the pair of props are arranged crosswise by 'X', and each end thereof is attached to and detached from the locking projections of the props. In addition, to enable the tension control after the fastening, it is composed of four cut steel pipes arranged in all directions around the tension control ring of the metal material placed in the center of the central cut portion of each steel pipe A structure comprising a plurality of cross reinforcing bar made of a threaded portion through the tension control ring and fastened to the nut and lock nut, respectively, Ladder member to extend the height by stacking and connecting at least one such structure; A plurality of casters connected to a lower end of each strut of the ladder member positioned at the lowermost part to allow the ladder member to be moved or fixed at a desired position by its own rotation and stop operation; A plurality of outriggers mounted on the lower ends of the struts of the ladder member to which the casters are coupled to support the struts to be stably settled without shaking in all directions; A plurality of struts respectively placed at four corners corresponding to each strut of the ladder member, a plurality of transverse supports enclosed and fixed along three adjacent sides formed by the arrangement of the respective struts, and the remaining work A structure comprising a handrail door that is opened and closed only in one direction to the inside and locked to a side, the fence member is connected to the upper portion of the ladder member located at the top; And a plurality of scaffold members fixed in the form of a hook between a pair of transverse supports facing the left and right sides of the ladder member.

In addition, the ends of each strut stand of the ladder member and the fence member are interposed with joint pins which are inserted into the connecting end portions of the strut stands between the strut stands to interconnect them. It is preferable to fasten at least one fastener to the connection end of the support so as to maintain the insertion state of the joint pin.
