1 is a perspective view showing a fastening device for a scaffolding footrest according to the present invention.

The clamping device for a scaffolding footrest according to the present invention comprises a clamping clamp 10 which is fastened to a scaffolding pipe or a support base 2 to one side of a work footrest 1 and encloses the upper end of the operation footrest 1 to be squeezed, A clamp 20 is fastened to the other side of the scaffold 1 by fastening it to the scaffolding pipe or support 2 and fastening the clamping clamp 10 to fasten the scaffold 1 to the scaffold pipe or support 2. [ .

The clamping clamp 10 is formed with a lower ring part 11 into which a scaffolding pipe or support 2 is inserted and a pair of supporting rods 11, And a pair of pressing and fixing legs 13 are formed at the upper ends of the supporting legs 12 so as to extend perpendicularly to the other side so as to surround the upper ends of the operation legs 1, And a drop-off preventing tab 14 is formed at the end.

The dropout preventing tab 14 protrudes upward from the end of the clamping fixture 13 in an arc shape or a square shape.

The binding clamp 20 has a lower ring portion 21 into which a scaffold pipe or a support base 2 is inserted and a pair of supporting rods 22 is extended and a retaining ring 23 is formed at the upper end of the support base 22 for binding the end of the compression cradle 13.

The retaining ring 23 is bent downward at an upper end of the support 22 so as to be bent downward so as to form a retaining groove 23a.

The shape of the clamp hook 10 and the lower hooks 11 and 21 of the clamping clamp 20 and the supports 12 and 22 are the same.

The clamping clamp 10 and the clamping members 12 and 22 constituting the clamping clamp 20 are provided with a tensioning portion 30 for maintaining the tightening and dismounting and the firmly clamped and fixed state by allowing the stretching force and the elastic restoring force to act, ).

These tension portions 30 are respectively formed on the support rods 12 and 22 and are formed so as to protrude in a curved shape so as to face each other outwardly from the pair of support rods 12 and 22.

According to the assembled clamp of the scaffolding footplate of the present invention constructed as described above, it is very easy and easy to construct the scaffolding footplate on the scaffolding pipe or the support frame.

FIG. 2 is a perspective view showing a fastening device for a scaffolding footrest according to the present invention. The fastening device according to the present invention is provided at a point where a work footrest 1 and a scaffolding pipe or support 2 intersect with each other So that the work footrest 1 is fixed to the scaffold pipe or the support base 2.

That is, the clamping clamp 10 is mounted on the one scaffolding pipe or support 2 of the operation footrest 1 and the other scaffolding pipe or support 2 of the operation footrest 1 on the opposite side thereof is fastened The clamp 20 can be mounted and the crimp hook can be coupled to the clamp 10 and mounted.

At this time, the clamping clamp 10 clamps the lower ring 11 to the scaffolding pipe or the support 2 positioned at one side of the operation pedestal 1 so that the support pedestal 12 is brought into close contact with one side surface of the operation pedestal 1 And a compression bonding table 13 bent in the other direction from the support table 12 is installed so as to cross the upper end of the operation table 1. [

The clamping clamp 20 clamps the lower hook 21 to the scaffolding pipe or support 2 located at the lower side of the operation footrest 1 so that the support stand 22 is in close contact with the other side of the operation footrest 1. [ And the fastening hook 23 is fastened to the upper end of the support table 22 so as to be hooked on the end of the compression fastening table 13, so that the attachment is completed.

At this time, there is no accident such that the engagement ring 23 is pulled outward from the compression bonding table 13 or the fastening is loosened by fastening the engagement ring 23 to the inside of the slip-off preventing jaw 14 of the compression fastening base 13 To provide a rigid fastening structure.

Since the tension unit 30 integrally bent by the support rods 12 and 22 provides a predetermined elastic action, the operator exerts a stretching force during the fastening process and the worker pushes the compression gripper 10 The operation of fastening or dismounting the retaining ring 23 of the lower ring part 21 can be performed more easily. In addition, in the engaged state, the tension portion 30 exerts an elastic restoring force to provide a firmly press-fit state.

3 to 4, the clamping device of the present invention is connected to the clamping clamp 10 at each point intersecting with the scaffolding pipe or the support 2 along the longitudinal direction of the operation footrest 1, A plurality of hook clamps 20 are provided as one set, thereby providing a firmly fixed state.

5, the tension unit 30 may include at least one tension member 30 and a tension member 30 in order to overlap the operation footrest 1 and to exert an elastic force and an elastic restoring force at the time of construction, .

In the fastening apparatus for a scaffolding footrest according to the present invention, the clamping clamp 10 and the clamping clamp 20 can be modified according to the shape of the scaffolding pipe or the support base 2.

That is, referring to FIG. 6, when the shape of the scaffolding pipe or support 2 is a rectangular frame or a triangular frame, the shape of the lower ring portions 11 and 21 may be deformed into a square or triangular shape It is.

In particular, when the scaffolding pipe or support 2 is formed of a frame having a shape of "a" or a straight line as shown in Fig. 7, the clamping clamp 10 has one And the clamping clamp 20 is configured such that the clamping clamp 20 has one support 22 and an upper end of the support 22 at the upper end of the lower loop 21, It is possible to deform the latching collar 23 in a bent shape with a simpler structure.

FIG. 8 is a perspective view showing still another construction of the fastening apparatus for a scaffolding footrest according to the present invention. In this case, it is possible to construct a construction in which a work footrest is laterally extended, And a connection fixture 40 for fixing the compression fixture 13 of the clamping clamp 10 in the housing 10.

The connection fixing member 40 is formed with a fixing hole 42 through which the pressing and fixing member 13 is inserted and fixed before and after the pressing member 41 which is in close contact with the operation foot plate 1, A pressing wing portion 43 for fixing the connection fixing piece 40 to the operation foot plate 1 is formed so that the pressing fixing block 13 is pressed so that one side of the pressing portion 41 is hit by the hitting means, So that the striking portion 44 is easily bent.

When the at least one operation footrest 1 is laterally extended, the two operation footrests 1 are fastened with the clamping clamp 10 and the clamping clamp 20, The first and second clamping clamps 10a and 10b are formed by further clamping the clamping clamp 10 at a midpoint between the work footrests 1 and the first and second clamping clamps 10a and 10b, The connecting and securing pieces 40 are fastened and fixed to the portions where the first and second pressing fasteners 13a and 13b are in contact with each other.

At this time, the first compression bonding clamp 13a of the first compression bonding clamp 10a is inserted into the fixing hole 42 of the connection fixing member 40, And the outer pressing wing portion 43 of the fixing member 42 is inserted into the lower portion of the first pressing hook 13b so that the first pressing hook is clamped by the connecting fixing member 40, Are fastened and fixed to the clamping clamp 20.
