Abstract

The present invention relates to a support bar for a worktable, which is installed on an outer wall of a wall of a building structure to perform attachment and detachment of the support bar supporting the worktable used as a foothold in case of high place work of a worker in a narrow bolting and coupling manner, thereby improving assembling properties and stiffness. To this end, the support bar for a worktable has a structure positioned between scaffolds which are temporary installations by coupling the support bar on which the worktable is placed to a metal strut material having a square cross-section installed on the outer wall, wherein the support bar comprises: a mounting part on which the worktable is placed; and fastening surfaces branching in a fork shape to be bolted and coupled to the strut material in a state of narrowing both sides of the strut material by being connected to one end of the mounting part.

Description

Support for increased stability in installation of a hypothesis board}

The present invention relates to a support bar installed on the outer wall of a building structure to support a worktable used as a scaffold during high-altitude work by a worker.In particular, the present invention relates to a support bar for a worktable that improves assemblability and robustness by using a clamping bolting connection to the support bar.

In general, building structures are constructed to a height of several tens of meters, and work is performed in the order of installation of work tables, reinforcement assembly, formwork installation, concrete placement, and dismantling.

Accordingly, concrete walls are constructed by assembling panels for formwork on both sides, binding hardware such as work tables and gaps, and installing support on both surfaces and placing concrete by placing rebars in the formwork.

In the process before and after construction of a building structure, manpower loss and work time delays due to assembly and dismantling of formwork including temporary materials such as support members and gaps are shortened due to poor work conditions due to high altitude work. There is a limit

In particular, the delay in the construction period was a problem due to the difficulty of installing and removing the support bar that supports the work table provided as a work space during high altitude work.

Another problem is that the fastening of the support bar is not sturdy, resulting in a safety accident for the worker. Another problem is the loss of logistics costs due to the inability to transport and store the support bar.

The present design was devised to solve the above problems, and the purpose of the present design is to install and detach the support bar that supports the workbench that is installed on the outer wall of the wall of the building structure and used as a scaffold for the operator's high-altitude work. It is to provide a support bar for work tables with improved rigidity.

The support bar is installed on the outer wall and is located between the scaffold and the outer wall, which forms a lattice structure, which is a facility necessary for carpenter's work, external discovery work, and installation of a safety net, and the work table is placed on the outer wall. It forms a structure that attaches and detaches to the support member, which is a metal material with a square cross section.

The support bar, which is attached to and detached from the support member, is connected to one end of the mounting part on which the worktable is placed, and bolt holes are formed so as to be bolted together in a state where both sides of the support member are constricted to form a structure with fastening surfaces branched in a fork shape.

The mounting part has a flat top surface for stable worktable mounting.

And with the fastening surfaces receiving the support material It forms a structure to be fastened in a state opposite to both sides of the support material, and both sides of the support material accommodated in the fastening surface form bolt holes for bolting connection with the fastening surface.

Therefore, the support bar according to the present design is a work table that provides a work space during high altitude work. By attaching and detaching the support bar to support the bolting method, the attaching and detaching process is relatively easy compared to the conventional welding method.

In addition to the workbench The entire bolt fixed with the tightening force of the nut has support against the worker's load through the bolt, and the load is distributed in a balanced manner across the bolt.

In addition, by transporting the support member and the support bar in a separate straight line and assembling it at the workshop, efficient loading is achieved in the limited cargo space of the transport vehicle.

The present invention has the effect of improving the working time and workability because the installation and separation of the support bar are relatively easy to attach and detach compared to the conventional welding method by attaching and detaching the bolting method.

And there is also an effect of securing a solid support by distributing the load that the entire bolt has a supportive power.

In addition, it has the advantage of reducing logistics costs by efficiently loading the limited cargo space of the transport vehicle by transporting the support member and the support bar in a separate straight shape and assembling it at the workshop.
