[Industrial applications]

 The present invention relates to a self-supporting metal support for a steel pillar used for supporting a PC balcony floor plate when a building is constructed by a laminated construction method, for example.

[0002]

[Background of device]

 In general, when installing a PC balcony floorboard on a building frame, in order to support this PC balcony floorboard, pipe supports (steel columns) are arranged in two rows in the front and back on the lower floor. The upper ends of these pipe supports are connected by heads, and the lower ends are connected by adjacent root gutters, so that they are kept independent so that they do not fall over.

By the way, the balcony portion plays a role as a passage between adjacent doors during construction, but there is root rust as described above between the pipe supports arranged in the front and rear two rows. However, there is a problem that this hinders the effective use of the balcony as a passage. In particular, when the partition wall between adjacent doors is a seismic wall with no doorway, it is not possible to move between adjacent doors except for the balcony, so securing a passage is a major issue.
