Description

[Detailed description of the invention] This invention relates to temporary construction equipment, and is an improvement in the connection part in particular.

Temporary construction equipment such as floor beams and handrail materials must be able to be constructed and dismantled quickly and easily, be safe, and be inexpensive. The aspect of ease is emphasized,
The quickness and ease of disassembly was a drawback.

This idea is to provide temporary construction equipment such as floor beams and handrails with locking holes for tightening in the connecting claws of the temporary equipment, as well as providing holes for dismantling above the locking holes. By providing a connecting part of temporary construction equipment, which has the same shape and size as the locking hole, and a part of which emerges from the connecting part of the material to be tightened when tightening, safety, The purpose is to enable quick and easy construction and disassembly without compromising affordability.

The illustrated embodiment is a case where this invention is applied to a floor beam. To explain based on this embodiment, reference numeral 1 denotes a floor beam, and connecting claws 3 connected to a floor jack 2 are provided at appropriate locations. A lock hole 4 for tightening is formed in the connecting claw 3 in the form of an elongated hole, and a disassembly hole 5 is formed above the lock hole 4. The disassembly hole 5 has the same shape and size as the lock hole 4, and is spaced at an appropriate distance from the lock hole 4 so that a portion thereof emerges from the connecting portion 6 of the floor jack 2 when tightened.
7 is a bolt for tightening.

In this invention, tightening can be done simply and quickly by bolt tightening, etc. in the same way as before, and disassembly can also be done by connecting part 6 of the material to be tightened (in this case, floor jack 2). Since it is exposed, if you insert a wedge-like object there and use it as a lever to turn it, you can easily and quickly dismantle it even if the connecting part is rusty. Further, since the dismantling hole 5 is punched out in the same shape and size as the lock hole 4, that is, in the same shape as the lock hole 4, no special cost is required for molding. Furthermore, since the locking hole 4 and the dismantling hole 5 are not integrated into a large elongated hole, even if a force is applied to the claw 3 in a direction perpendicular to the elongated hole (in the direction of the arrow), it is safer than an integrated hole.

As described above, this invention has the advantage that temporary construction equipment can be constructed and dismantled quickly and easily without sacrificing safety or affordability.
