Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a safety handrail for PC board erection.

(Prior art) When the scaffolding construction method is adopted in the PC board construction method of PC construction, it is necessary to install a safety handrail on the upper part.

For this reason, conventionally, it has been proposed to drive a pipe onto a slab to form a handrail post.

(Problems to be solved by the invention) However, the conventional method has poor workability, and
It is difficult to ensure safety when assembling beam reinforcement.

The present invention has been proposed in view of the above-mentioned problems of the prior art. The purpose of the present invention is that the safety handrail is easily attached on the ground portion before the PC board is lifted, and the installation and rearrangement are easy. The point is to provide a safe handrail for PC board construction with good workability.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the safety handrail for PC board erection according to the present invention has a groove type handrail receiver fastener mounted on the inner surface of the outer wall PC board, and a horizontal rope hook. A ring-shaped fastener attached to the lower end of the handrail provided with a mounting ring and a tubular horizontal handrail attachment clamp is fitted, and both fasteners are detachably connected via a lock pin.

(Operation) Since the present invention is configured as described above, before the PC board is lifted, the groove type handrail receiver fastener mounted on the inner surface of the PC board is attached to the groove type handrail receiver lower end. Attach the handrails to the PC board by fitting the fasteners and fixing both fasteners with a lock pin with a one-touch, and attach the tubular horizontal handrails to the handrail clamps provided on the handrails. Is attached in advance before the PC board is hung.

Moreover, the main net rope can be attached by using the horizontal rope hooking ring arranged on the handrail.

Furthermore, since the handrail is removably attached to the PC plate through the lock pin using the groove type fasteners provided on the both members, removal and refilling work can be efficiently performed.

(Embodiment) The present invention will be described below with reference to the illustrated embodiment.

(A) is an outer wall PC plate, (1) is an existing groove type vertical fastener fixed to the inner surface thereof, and mounting holes (2) are formed in both side flanges thereof.

(B) is a handrail made of square pipe, and a groove type fastener (3) fitted to the fastener (1) is welded to the lower end of the handrail.
Mounting holes (4) are formed on both side flanges of the fastener (3) at positions corresponding to the mounting holes (2) of the fastener (1).

A horizontal rope hooking ring (5) and a tubular horizontal handrail attachment clamp (6) are attached to the handrail (B).

Before lifting the PC board (A), the handrail (B) is attached to the groove-shaped vertical fastener (1) of the PC board (A) at the ground portion.
Groove-type fastener (3) is fitted, and both fasteners (1)
The lock pin (7) extends over the mounting holes (2) and (4) of (3).
And fasten both fasteners (1) and (3) with one touch.

In addition, by attaching a tubular horizontal handrail across the clamp (6) of the handrail (B), the PC board (A)
The handrail (B) and the horizontal handrail are attached to the ground portion before the suspension.

Thus, the safety handrail is assembled at the same time when the PC board is hung, and the main net rope can be stretched over the ring (5) if necessary.

Further, the above-mentioned safety handrail can be used also as a gantry at the time of beam reinforcement.

Furthermore, by attaching and detaching the lock pins (7) to the both fasteners (1) and (3), the safety handrail can be easily removed and re-filled.

(Effect of the Invention) As described above, the present invention is a handrail in which a horizontal rope hooking ring and a tubular horizontal handrail attachment clamp are arranged on a groove type handrail receiver fastener attached to the inner surface of the outer wall PC plate. By fitting the groove type fasteners attached to the lower end and connecting both fasteners detachably via the lock pins, the handrail can be easily attached on the ground before the PC board is lifted, and it can be removed and replaced. It is easily performed and workability is improved.

Further, the horizontal net hanging ring provided on the handrail can be used to stretch the main net to further improve safety.

Furthermore, the above-mentioned safety handrail can be used as a gantry at the time of rebar reinforcement.
