Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a footrest fixing device,

More particularly, the present invention relates to a footrest fixing device, and more particularly, to a footrest fixing device and a stiffener having the footrest and a footrest for supporting the footrest. The fastening means can be directly connected to the clamping portion so that the fastening means can be directly connected to the clamping portion, The present invention relates to a footrest fixing device and a provisional body including the footrest fixing device.

Generally, when drying a structure such as a ship or a building, a setter is installed for a high-altitude work, and the setter is connected to a large number of scaffolds such as a scaffold or a chieftain to provide a pathway to an operator.

However, in order to connect a plurality of scaffolds, it is necessary to connect the scaffolds adjacent to each other in the longitudinal direction so as to overlap each other, and then to bind the scaffolds extending in the longitudinal direction using wires. And disassembly is inconvenient.

In addition, there is a risk that a safety accident may occur due to carelessness or the like of the worker because the degree of binding of the wires connecting the foot plates is not uniform.

On the other hand, Korean Patent Registration No. 10-1588868, to which the present applicant has previously registered, discloses a footrest fixing apparatus and a provisional body having the footrest fixing apparatus.

However, such a conventional footrest fixing device has a problem that it is not easy to work because the fixing pin must be connected to a fastener constituting a connecting portion in a state where the fixing pin is connected to the clamp.

In addition, there is a possibility that the fixing pin may be detached from the clamp when a pair of side clamps are opened due to external impact or the like.

The connecting member 11 is screwed to the first body 33a through the second body 33b and is moved downward by the releasing member 41 in accordance with the releasing rotation of the fastening member 31, And at the same time, escape is prevented.

Therefore, it can be understood that the clamping unit 10 is lifted and lowered only by the first body 33a in accordance with the tightening or unclamping rotation of the fastening tool 31.

As shown in FIG. 3, the first body 33a is larger in diameter than the second body 33b, and the lower end of the first body 33a forms a lift-up prevention claw 33c.

The lifting and lowering restricting jaw 33c abuts against the releasing rest 41 to prevent the releasing rest 41 from being lifted up from the second body 33b to the first body 33a.

As shown in FIG. 2, the escape chamber 41 is formed with an escape prevention hole 41a passing through the inside in the vertical direction, and is coupled to the second body 33b.

The second body 33b is threaded on the outer circumferential surface of the second body 33b so that the second body 33b can be screwed to the second body 33b while forming a thread on the inner circumferential surface of the second body 33b. have.

At this time, the first and second bodies 33a and 33b may be formed in a direction opposite to the thread formed on the outer circumferential surface.

That is, the clamping portion 10 and the release preventing portion 41 are moved in the opposite directions to each other in the upward and downward directions as the body portion 33 is rotated in the left or right direction.

This is to prevent the escape preventing zone 41 from being separated while being in contact with the connecting member 11 descending in accordance with the rotation of the fastening member 31 while moving in the same direction.

3, the stopper 40 may further include a flange 42 extending outward from the lower end of the second body 33b.

The flange 42 is in contact with the escape chamber 41 to prevent the escape chamber 41 from escaping from the second body 33b.

The flange 42 may protrude outwardly as the lower end of the second body 33b is pressed against the second body 33b and the connection member 11 and the release- It is a matter of course that they are formed in a combined state.

The escape chamber 41 is screwed to the second body 33b while being prevented from being lifted and lowered by the escape prevention pin 33c and the stopper 42 to maintain a stable stop state without rotating .

In addition, the fastener 31 and the clamping part 10 can be maintained in a mutually stable state of engagement by the releasing rest 41 and the flange 42.

An upper plate 21 having both side portions and extending in a direction intersecting the lateral direction of the foot plate 110 and being seated on one side or the other side of the foot plate 110; And a spacing portion 22 located below the upper plate 21 and contacting the side surface of the foot plate 110 to prevent the upper plate 21 from flowing.

1 to 2 and 5, one side of the upper plate 21 is seated on a foot plate 110 disposed at the edge of the footrest structure 130, As shown in FIG. 7 to FIG. 7, both side portions may be seated on two foot plates 110 adjacent to each other.

The footrests disposed at the edges of the footstool structure 130 are preferably understood to be footsteps disposed at both ends of the footstep structure 130.
