FIG. 1 is a block diagram of the entirety of the present invention, FIGS. 2 and 3 are partial block diagrams of the present invention, FIGS. 4 and 5 are partial perspective view of the present invention, The present invention relates to a work clamping device comprising a fixed clamp 40 fixed to a work table 1, a column 10 fixedly coupled to the fixed clamp 40, and a pipe clamp 20 fixedly coupled to the column 10 The pipe clamp 20 includes a bracket 21 and a wedge 30 coupled to the bracket 21 and fixing the pipe 2. The bracket 21 is fixed to the bracket 21, The teeth 22 are formed to increase the fixing force of the pipe.

A gear 25 is fixedly coupled to the bracket 21, and the gear 25 is interfered with rotation by a spring 27.

First, the workbench 1 is used in a shipyard, a subway, or an apartment construction site. Such a workbench 1 is also referred to as a conventional standblock, and a workbench 1 used in the shipbuilding is provided at the edge of the shipblock to prevent workers from falling It is a scaffolding hypothesis.

Since the stationary clamp 40 is fixed to the worktable 1, the stationary bar is fixed to the worktable 1. The detailed structure of the stationary clamp 40 will be described later.

A pipe clamp 20 is coupled to the column 10 and the pipe clamp 20 includes a bracket 21 and a wedge 30 coupled to the bracket 21 and fixing the pipe 2 do.

3, the bracket 21 may be divided into a male bracket 21a and an arm bracket 21b. Alternatively, the bracket 21 may be integrally formed by bending a casting or an iron plate.

That is, when the bracket 21 is divided into the male bracket 21a and the female bracket 21b, the male bracket 21a and the female bracket 21b are very similar in outer shape and only the male bracket 21a A protrusion 24 is formed on one side to make a space for the wedge 30 to move and the male and the female brackets 21a and 21b can be joined by welding or screw, 2, the teeth 22 having a shape repeated in the mountains and the valleys are formed.

The pipe 2 fixed to the bracket 21 is subjected to a strong fixing force by the teeth 22 so that the fixing force of the pipe 2 by the pipe clamp 20 can be improved, It is possible to prevent the pipe 2 from bouncing due to the repulsive force.

That is to say, when the surface of the bracket 21 which is in direct contact with the outer surface of the pipe 2 is flat, if a strong impact is applied at the upper part of the wedge 30, There is a possibility that a safety accident may occur due to the protrusion, and the tooth 22 improves the frictional force with the outer surface of the pipe 2, thereby reducing such concern.

The wedge 30 may be formed between the male bracket 21a and the arm bracket 21b so that the wedge 30 can be made of a synthetic resin, Since the male bracket 21a and the female bracket 21b are semi-permanently engaged by welding or the like, they are kept in a state in which they are not separated therebetween.

A total of three pinholes are formed in the male bracket 21a and the female bracket 21b. Pinholes 28a and 28b are formed on the upper and lower portions of the bracket, respectively, and pinholes 29 are formed between the pinholes.

The fastening pin 23a is inserted into the upper pinhole 28a through the guide groove 31 formed in the wedge 30 so that the wedge 30 is engaged with the fastening pin 23a, And the gear 25 is rotatably coupled to the lower pinhole 28b.

The gear 32 is engaged with the gear 25 at one side of the wedge 30 so that the wedge 30 is moved in a state where the gear 25 and the gear 32 are engaged with each other. The gear 25 is interfered with the rotation by the spring 27 fixedly connected to the bracket 21 by the fixing pin 26. [

That is, the gear 25 is coupled to the coupling pin 23b so as to be rotatable, but is restricted by the movement of the spring 27 coupled to one side of the gear 25, and the shape of the spring 27 The gear 25 rotates while pushing the spring 27. As a result, Therefore, the wedge 30 must be rotated in order to move the wedge 30, so that the wedge 30 is also restricted by the spring 27.

A guide groove 31 is formed in the wedge 30 and a male bracket 21a and an arm bracket 30b are formed in the guide groove 31. The male and female brackets 21a, The fastening pins 23 for fastening the wedges 30 are guided by the fastening pins 23. As shown in FIG.

4, the wedge 30 is lowered to the lower side of the bracket 21. In this state, the fastening pin 23a is positioned on the guide portion 31a of the guide groove 31 , And the pipe can be fixed by the wedge 30 and the bracket 21. 5 shows a state in which the fastening pin 23a is positioned on the fastening portion 31b at the end of the "J" -shaped guide groove 31 and the position of the wedge 30 is maintained by the weight of the wedge 30 Can be maintained. 5, the pipe 2 is inserted into the groove of the bracket 21 where the teeth 22 are formed, and then the wedge 30 is moved to the state shown in FIG. 4 Thereby fixing the pipe 2.

Actually, the configuration for fixing the wedge 30 can be very convenient for the user. When the pipe 2 is inserted or removed between the pipe clamps 20, the wedge 30 is fixed The operation of inserting or removing the pipe 2 between the brackets 21 can be facilitated without holding the wedge 30.

One side of the wedge 30 is inclined at a predetermined angle with respect to a vertical plane so that the wedge 30 is inserted into the bracket 21 in a downward direction, The distance between the grooves 22 is reduced so that when the upper surface of the wedge 30 is hit by a tool such as a hammer and inserted into the bracket 21 while the pipe 2 is inserted into the groove of the bracket 21, 30 firmly fix the pipe 2 to the bracket 21 while pushing the pipe 2 toward the surface where the tooth 22 is formed.

In order to disassemble the pipe 2 and the pipe clamp 20, when the wedge 30 is moved to the upper part of the drawing by hitting the lower surface of the wedge 30 with a tool such as a hammer, The pipe 2 pushed into the groove can flow and the pipe 2 can be separated from the pipe clamp 20 in this state. In order to separate the pipe 2 from the pipe clamp 20, The distance between the bracket 21 and the wedge 30 should be at least as large as the diameter of the pipe so that the wedge 30 ascends as shown in Fig.

The guide groove 31 reduces the weight of the wedge 30 so that the entire weight of the pipe clamp 20 can be reduced. In order to separate the wedge 30, the lower surface of the wedge 30 is guided by a tool A pipe or a reinforcing bar having a diameter smaller than the width of the guide groove is inserted into the guide groove 31, and the pipe or the reinforcing bar is struck with the wedge The state in which the pipe 30 is fixed by the pipe 2 can be released.
