Description

System scaffold

The present invention relates to a system scaffold. More specifically, it is possible to install scaffolds on a high place by a worker alone, so that the installation can be performed quickly and accurately. In addition, it provides ease of installation and ease of use, And the dismantling work time can be remarkably shortened, and an innovative system scaffold that can guarantee the safety of the worker working at a high place to the maximum is provided.

Generally, a scaffold is a temporary installation that is installed in a high place such as a construction site, a construction site, and a shipyard so that an operator can work stably, and a worker carries various materials or becomes a space for worker's passage and work.

A lot of prior arts have been developed to stably install the scaffold at a high place. Prior arts include a scaffolding arrangement such as Korean Registered Patent No. 10-0698509 and Korean Registered Patent No. 10-0835681, The prior art of the scaffolding installed on the scaffold for the foot is installed at a certain height of the scaffold, such as Korean Registered Design Bulletin 30-0471242, Korean Registered Design Bulletin 30-0625395, so that the worker can carry the work, You can.

Conventionally installed scaffold is constructed by installing a clamp so that a horizontal pipe can be connected to a vertical pipe in the state that four vertical pipes are standing up, and a foot is combined with a horizontal pipe so that an operator can walk or work. In order to connect the pipe, the clamp must be firmly fastened. However, when the clamp is fastened to the vertical pipe at a high position, strong force is not transmitted and the clamp is loosely fastened. There is a problem that the clamp must be firmly fastened again to the clamp, and a worker may fall or a scaffold may collapse due to the clamp which is loosely fastened in several clamps due to the operator's mistake, .

In order to solve the problem of the scaffold, a flange having four fixing holes in a vertical pipe is installed at a certain height, a connecting hole formed at both ends of the horizontal pipe is formed, and a wedge is inserted into the fixing hole of the flange In order to install the horizontal pipe and the footplate on the scaffold of the scaffold, hold one side of the horizontal pipe and lift it upwards and insert it into the fixing hole of the flange Since one wedge is struck down by the load, there is an inconvenience that the horizontal pipe must be lifted up until the end of the wedge is connected to the fixing hole so that the wedge can be inserted into the fixing hole. It is hard to fit into the hole correctly and a skilled worker There is a problem in that it takes much time. In order to insert the opposite side of the horizontal pipe into the fixing hole of the flange while one side of the horizontal pipe is coupled to the flange, the working time and working method are changed according to the body of the worker. It is impossible to guarantee the safety of the worker because it is necessary to lift the body as much as possible or to hold the vertical pipe and to lift the body as much as possible. There was a problem that could cause an accident.

The inventor of the present invention has made it possible to easily install and disassemble even a novice without a safety accident in the process of installing a scaffold in a high place, It is possible to shorten the working time and to provide the system scaffold which can be installed by the worker's own manpower.

The present invention relates to a vertical pipe installed on the ground; A flange formed at a predetermined distance from the vertical pipe, the flange having fixing holes formed at four sides thereof and having a hollow inserted into the vertical pipe at the center; A horizontal pipe formed at both ends thereof with a shaft connecting frame constituting a shaft hole into which an axial pin is inserted and having a connecting hole to be engaged with a projecting piece of the flange at both ends; A fitting protrusion fitted into the fixing hole of the flange at an inner center of the fitting; An auxiliary pipe having a shaft connecting portion formed at one end thereof with a pin hole so as to be inserted into the shaft connecting frame and to be installed therein; An engaging member provided at an opposite end of the auxiliary pipe so as to be inserted into the projecting piece of the flange and having guide grooves formed on both sides thereof and having wedge guide holes formed in the upper and lower portions thereof; And a wedge formed at an upper portion and a lower portion to prevent the wedge guide hole from being detached from the wedge guide hole.

Also, in the present invention, a superimposed portion is formed at the center of the auxiliary pipe so as to prevent the auxiliary pipe from being bent when the auxiliary pipe intersects with the 'X' shape.

In this design, the system scaffold can connect the horizontal pipe to the vertical pipe with the work force of the worker alone, and it is easy to install even if the horizontal pipe is installed on the high place. Therefore, it provides convenience to the operator and can shorten the working time remarkably. Effect can be provided.

The system scaffold is provided with a horizontal pipe and an auxiliary pipe which is inclined diagonally so as to prevent the vertical pipe from being bent or twisted to provide an effect of more firmly supporting the loads generated in the upper and the lower sides will be.

The horizontal pipe can be fastened to the fixing hole of the flange quickly and precisely, and the horizontal pipe can be firmly fixed without detaching.
