Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building frame used as a scaffold member when constructing a building or the like, and more particularly to a building frame with a safety net used for curing an opening at the end of a scaffold.

[0002]

2. Description of the Related Art Conventionally, a torii form or a ladder form which is a steel frame scaffold member is generally used as such a building frame, and when forming a multi-layered scaffold, it falls or flies. In order to prevent this, a curing frame or a curing net was stretched over the outer surface of the scaffold and the end openings. In particular, the opening at the end of the scaffold was carefully cured because there is a risk of a fall accident.

A conventional curing frame used for curing the end of a scaffold has a structure in which an expanded metal is fixed to a rectangular frame material, and a plurality of curing clamps are attached to the building frame of the building frame to project into this curing clamp. The joints to be installed engage the holes formed in the frame material of the curing frame, and are attached to the building frame one by one. Further, when the scaffolding end is to be cured with a curing net, a skirting board and a handrail are installed, and then a long mesh sheet is firmly fastened to a building frame with a string or the like.

[0004]

However, the conventional mounting of the curing frame and the curing net is a laborious work, and the mounting work always involves danger. In particular, the work of mounting the curing frame had to be performed one by one for each layer, and it took a long time to carry in, mount, dismantle, and carry out the members.

Further, since the work of fastening the curing clamp, the cord and the like is done manually at each location, there is a possibility that the fastening strength may vary. Furthermore, once these curing frames and curing nets have been attached, it was not easy to remove them, so it was difficult to open and close them appropriately according to the material loading and the like.

The present invention solves the above-mentioned drawbacks of the conventional building frame in which a curing frame or a curing net is stretched for curing the opening at the end of the scaffold, and therefore the building frame with a safety net according to claim 1 Locks a safety net with a frame that can be folded in two and is removable to the building frame to simplify the curing work, prevent the tightening strength from fluctuating, eliminate dangerous work, and respond to material loading. The purpose is to provide a building frame that can open and close the safety net as appropriate.

The building frame with a safety net according to claim 2 is
It is an object of the present invention to provide a simplified construction frame with a safety net with a low cost by adopting a configuration in which one safety net with a frame can be shared between the upper and lower construction frames that are stacked. Further, the building frame with a safety net according to claim 3 is configured such that a plurality of layers of the building frame are integrated, so that the building frame for curing is mounted and disassembled at once by using a crane or the like, and the work is performed.
