Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a handrail frame for preventing a fall which is attached when a frame scaffold used for a construction site or the like is assembled or is directly attached to the frame scaffold.

<Prior art> A frame scaffold generally has two gate-shaped metal building frames facing each other, and a scaffold plate (cloth frame) or a horizontal rail is horizontally attached to the upper part of the scaffolding to fix the frame. Furthermore, a scaffolding of one unit, which is formed by diagonally straddling braces, is configured to extend upward or leftward and rightward.

When assembling these frame scaffolds sequentially from the bottom, in order to protect the safety of workers who ride on the top scaffold,
A rope was laid horizontally above the top scaffold along the scaffold, and workers were connected to this with a safety belt to ensure safety.

Also, as another conventional frame scaffolding, a special H-shaped building frame is used instead of the gate-shaped building frame of the framed scaffolding, and scaffolding boards are placed at the place that hits the horizontal bar at the middle height of this H-shaped scaffolding. A configuration has been known in which fitting protrusions are provided so that handrail frames can be erected on both sides of this height while being handed over, and thereby the handrail frames are provided. In such a conventional frame scaffold, the upper end of the H-shaped building frame is fitted to the lower end of the next H-shaped building frame to sequentially form the framed scaffolding upward.

<Problems to be solved by this device> In assembling such a frame scaffold, a rope or a handrail frame for protection was provided for the safety of the worker who works on the scaffold plate on the top floor. However, there were the following problems.

In the structure in which the rope is hung, there is a problem in that the rope for hanging the worker must be further hung on the rope, which is troublesome for the worker and the hanging rope hinders the work.

Further, the conventional frame scaffold provided with the handrail frame for each floor has a problem that it cannot be applied to a general frame scaffold because a special H-shaped building frame is used.

An object of the present invention is to provide a handrail frame for protection which can be easily attached to a gate-shaped building frame which has been generally used conventionally.

Is configured to be caught.

The grip 15 pulls out the tip end of the wedge-shaped body 18 from the insertion hole 19 and locks only the insertion hole 20 with the hook portion 21 to open the opening 16. And the building frame 1 from the opening 16 side
By inserting the pedestal 4 up to the grip portion 17, inserting the wedge-shaped body 18 into the insertion hole 19, hitting the thick side end of the wedge-shaped body 18 with a metal punch, etc., and fitting it into the insertion holes 19 and 20. Grasping and fixing the pedestal 4.

When removing the grip fitting 15 from the pedestal 4, contrary to the case of fixing, the wedge-shaped body 18 is tapped from the tip side with a hammer or the like to move the wedge-shaped body 18, and the grip fitting 15 and the pedestal 4 are dissociated. Let

In order to stand the handrail frame 10 on the frame scaffolding, the scaffolding plate 2 is laid over the building frame 1 which is standing and opposed, and the locking projections 7 of the pedestals 4 are provided.
After the brace 3 is provided on the rail, the locking hole 13 of the locking body 12 of the handrail frame 10 is inserted into the locking projection 7 in the same manner as the brace 3, and the rotary locking piece 8 is rotated by gravity to lock. At the same time, the grip 15 is fitted to the pedestal 4 of the building frame 1, the wedge-shaped body 18 is struck, and the handrail frame 10 and the pedestal 4 are securely gripped and fixed.

In this way, the handrail frames 10 erected on one set of scaffolds are assembled as they are as frame scaffolds while being attached as they are.

<Effect of device> Therefore, according to this device, when assembling a frame scaffold, a handrail frame for protecting safety such as fall prevention of workers from the scaffold plate can be used for a commonly used building frame, Moreover, there is an effect that it can be attached and detached very easily.

Further, it is possible to increase the number of the locking bodies and attach them in consideration of factors such as the length and weight of the scaffolding plate.
