[Prior art]
Conventionally, as this kind of foldable support structure, a floor member that is foldable between a pair of support frame members formed in a square shape by connecting a pair of support columns on both sides is rotatable. It is known that a telescopic strut is pivotally attached to both sides of the support frame member in an intersecting manner, and a horizontal bar can be attached to both sides of the upper end portion of the support frame member ( JP, 9-195530, A).
When assembling the conventional support constructed as described above, the support frame members on both sides are lifted by a crane or the like, the extension struts on both sides are extended and locked, and the floor member is shaped like a flat surface. In addition, the upper end sides of the both side support frame members are connected to each other with a horizontal hook and then assembled, and then lifted by a crane or the like to stand up.
On the other hand, when folding, the crane is lifted by a crane or the like and then laid down, and then the heel is removed, the lock of the elastic band is released, and the connection of the floor member is released. And while extending | stretching a telescopic brace by the dead weight of a supporting frame member, it is supposed that a floor member is folded and folded.
[0003]
[Problems to be solved by the invention]
The conventional example configured as described above can be reliably assembled and folded, but has the following problems.
First of all, since the support frame members on both sides are connected to each other by an elastic bar and a bendable floor member, the elastic bar can be freely expanded and contracted during assembly, and the floor member is also bent. To do. For this reason, not only the locking operation and the connecting operation of the floor member at the time of extension of the elastic bar, but also the installation work of the reed is very troublesome and troublesome, and the assembly work efficiency as a whole is very poor.
Second, at the time of assembly, it must be lifted and assembled by a crane or the like, and then it must be lifted to stand up. The assembly work is very troublesome and troublesome, and the work efficiency is extremely poor. The same applies to folding.
Thirdly, when supporting structures are formed in multiple layers as needed, the supporting structures of the same shape must be stacked on the supporting works one after another, and the struts constituting the supporting works must be connected. It is cumbersome and time-consuming, and the same applies when folding.
Fourthly, since the support frame members on both sides are supposed to be folded through the stretcher brace and the foldable floor member, it is not possible to assemble the stairs linked to the folding of the both side support frame members, As a result, it must be assembled later at the time of assembly, which is very troublesome.
