Description

  The present invention relates to a vertical bar arrangement device for efficiently arranging vertical bars such as columns and walls in reinforcing bar construction.

  Conventionally, in reinforcement work such as pillars and walls in rebar construction, the vertical bars are carried to the groundwork where the upper and lower scaffolds are provided, and the workers placed on each scaffold move one vertical bar at a time. While positioning, horizontal bars such as hoop bars are joined together to form a three-dimensional reinforcing bar rod. Reinforcing rods formed in this groundwork site are suspended from a construction site by a crane or the like, and each vertical bar is connected to a vertical bar on the lower layer side. In the case of a reinforcing bar rod such as a wall, it may be connected to an adjacent reinforcing rod rod.

  Longitudinal bars such as pillars and walls are several meters long and difficult to handle, and the upper scaffolding such as the groundwork is quite high, so the conventional bar arrangement work is extremely workable. There was a problem that was bad and accompanied by the danger of working at height. For such a problem, there is a bar arrangement device in which the upper end portion of the vertical bar to be laid is suspended through an attachment and moved to a position where it should be joined to the horizontal bar (see, for example, Patent Document 1). .) In the device disclosed in Patent Document 1, a curtain-type rail is disposed on a gate-shaped upper beam having wheels disposed on legs, and a bar arrangement device or an attachment that hangs an attachment freely on the rail. A bar arrangement device has been proposed in which a beam member on which a suspended curtain rail is arranged is suspended by a crane.
