Description

  The present invention relates to a work scaffold with a supplementary panel used in various construction sites such as construction, civil engineering work, road bridge construction, plant construction, and tank construction.

  At the various construction sites described above, a large number of scaffold panels are connected to assemble a suspended scaffold and a fixed scaffold. There exists patent document 1 as an example of the panel for scaffolds. As shown in FIG. 12, this scaffolding panel A is provided with round pipes (frame pipes) C at both ends in the longitudinal direction (length direction) of the two elongated members B, and a reinforcing horizontal cross between the frame pipes C. A rectangular plate material (for example, a metal flat plate, a panel material, an expanded metal, or other plate material) E is disposed and fixed on the upper surface of the peripheral frame provided with the material D. When assembling a work scaffold by connecting these scaffold panels A, the scaffold panels A arranged in the narrow width direction (width direction) are connected to each other via the connector F and arranged in the longitudinal direction. Frame pipes C are connected by a clamp. The clamp shown in FIG. 11 is a clamp in which two single clamps are connected back to back (so-called universal clamp) or a clamp in which two single clamps are connected back to back so that both clamps do not rotate (the applicant This is called a parallel clamp.)

Japanese Patent No. 2647802

  When the scaffolding panel A is connected as shown in FIG. 12 to assemble the work scaffold, the working scaffold has a short length (for example, 50 cm or 1 m) in the longitudinal direction (panel connection direction), and the working area of the suspended scaffold is short. May be missing. In this case, if there is a panel with a length of 50 cm or 1 m, it is sufficient to connect it to the work scaffold, but currently there is no such panel for a scaffold and such connection is not possible. As shown in FIG. 12 used for assembling the scaffold, the scaffold panel A may be connected by changing the orientation by 90 degrees. Since the scaffold panel A has a minimum length of 2 m and a width of 66 cm, the basic dimensions are as shown in phantom lines in FIG. 12 is inserted into the side opening H of the frame pipe C of the scaffolding panel A arranged in the narrow width direction so as to connect the scaffolding panels A to each other. The scaffold panel A arranged like a virtual line cannot be connected to the work scaffold by the connecting tool F. The clamp shown in FIG. 12 (hereinafter, the universal clamp and the parallel clamp are collectively referred to as “connection clamp” in the present application) is placed on the outer periphery of the frame pipe C adjacent to the scaffold panel A arranged in the longitudinal direction. Since it is to be gripped, it is not possible to grip the frame pipe C of the scaffolding panel A arranged like the virtual line.

  As shown by phantom lines in FIG. 12, a panel (supplementary panel) J having the same shape and dimensions as the scaffolding panel A is connected (added) perpendicularly to the panel arrangement direction of the suspended scaffolding. J was piled on the tip of the suspension scaffold, and the next supplement panel J had to be connected to the side of the supplement panel J. In this connection method, since there is a step between the work scaffold and the replenishment panel J, there is a risk that the operator may go to the step, and the safety of the work has not been ensured. In addition, the level difference sometimes hindered the carrying of materials onto the suspended scaffolding.
