However, the conventional safety footrests as described above have a problem in that an empty space is generated as the distance between each safety footboard disposed adjacent to each other is widened, thereby reducing safety.

That is, there is a problem in that a safety accident occurs, such as a worker falling out of a foot in an empty space between safety footrests and a work tool falling.

In addition, the temporary scaffolding system consists of a single coupling structure in which each safety scaffold is fixed to the holding structure, and as each safety scaffold forms an independent support and fixing structure, there is a problem of poor structural stability.

That is, there was a problem in that the stability of work was reduced because the flexibility of the safety scaffolds independently coupled to the holding structure was increased.

The present invention has been proposed to solve the above conventional problems, and an object of the present invention is to be installed while being fixed to a plurality of scaffolding pipes that intersect and bind each other to form a safe floor for workers with respect to the work space. It is structurally simple and can be economically produced. In particular, workability is improved to quickly perform facility work, and there is no clearance error when combining safety scaffolds. An object of the present invention is to provide a scaffolding integrated fixing device designed to realize structural safety on the work floor.

Another object of the present invention, as the safety scaffolds fixed by the scaffolding pipe are firmly bound to each other so that the safety scaffolds are integrated, the independent flow of each safety scaffold is significantly reduced to further secure the structural stability. It is to provide the device.

In order to achieve the object of the present invention as described above, the scaffolding integrated fixing device according to the present invention is provided at close contact ends facing each other in each frame frame of each safety scaffolding to be connected, and is fitted to each other. A male fixing means that is coupled and fixed by combining a pair of male and female while being fitted; And arm fixing means; At the lower end of the close end portion provided with the arm fixing means, a support piece extending outwardly is provided to support and support a portion of the bottom portion of the close end portion provided with the male fixing means.

In addition, the support piece, while accommodating the lower end of the close end portion provided with the male fixing means, support coupling recessed portion to be fitted and coupled; characterized in that provided.

The scaffold integrated fixing device according to the present invention made as described above, when the safety scaffolds are connected to each other and fixed while integrating through a pair of male fixing means and arm fixing means customized fitting, workability is improved and facilities are quickly installed. In addition to performing the work, there is no clearance error when the safety scaffolds are coupled through the binding of the fixing rod and the fixing portion, and the support piece and the support binding portion, thereby having the effect of realizing structural safety for the work floor.

Accordingly, the independent movement of each of the safety footrests is remarkably reduced, which has an effect of further securing the safety of the operator during work.

In addition, it can be provided economically because it is structurally simple, and has an effect of improving usability.
