The present invention relates to a wedge-type pipe clamp, and more particularly, to a wedge-type pipe clamp capable of implementing a clamping operation by striking a slider in a wedge manner.

As is well known, a scaffold refers to a temporary scaffold installed on the outside of a building so that the worker can work at a high place during construction, and a representative example is a steel pipe scaffold.

The steel pipe scaffold is excellent in durability and is easy to assemble and disassemble, and is usually composed of vertical and horizontal pipes, scaffolds, and a plurality of clamps.

Among the above components, the clamps are one of the most important components directly connecting the durability of the steel pipe scaffold as a means of binding the vertical and horizontal pipes and also supporting the scaffold on the horizontal pipe.

Typically, the scraper comprises a vertical frame installed vertically apart from the vertical frame, a horizontal frame connected horizontally between the vertical frames, one end connected to the vertical frame, and the other end fixedly mounted on the building wall A support frame for supporting the vertical frame and a brace for clamping the end of the support frame and the tip of the support frame to the horizontal frame and clamping the end of the support frame to the horizontal frame to prevent tension and compression due to horizontal force.

On the other hand, the braces, the vertical frame and the horizontal frame are connected to each other through a scaffold clamp. As a representative prior art related to this scaffold clamp, Korean Utility Model Publication No. 20-2008-0006223 Clamp coupling structure) (hereinafter referred to as prior art).

The prior art includes a first body in which a pipe is drawn inward and a hemispherical inner surface is formed and a first fitting hole is formed on an inner surface of the first body, a hinge fastened to one side of the first body by a hinge pin, A clamp having a second body having a hemispherical inner surface, a bolt provided on an upper side of the first body and a nut fastened to the bolt to fasten the first body and the second body, A bracket having a joint surface communicated with the inner surface of the second fitting hole coming to a position corresponding to the first fitting hole provided in the inner surface of the body and a coupling surface extending from the joint surface and having a fastening hole penetrating through the fastening hole, And a fastening member connected to the first fitting hole and the second fitting hole of the bracket so as to have fixing flanges formed at both ends thereof.

However, in the prior art, the pipes are wrapped around the first and second bodies, and then the first and second bodies are fixed to the pipe using bolts and nuts. In this clamping method, The bolts and the nuts must be tightened again, so that the clamping operation becomes troublesome.

2 to 4, the construction wedge-type pipe clamp of the present invention comprises a main body 10, a locker 30, and a slider 40.

The main body 10 is a component constituting the outer shape of a scaffolding clamp for building, and has a front plate 12 in a forwardly open state with its rear open in a " And the side plates 14 are each formed into a vertically bent configuration.

A bolt 20 is protruded from the front plate 12 of the main body 10 and a nut 22 is fastened to the bolt 20 in a state where one end of the brace B is engaged.

Grooves 18 are formed at the upper ends of the side plates 14 that are vertically bent at both sides of the front plate 12 and pipes P are placed on the grooves 18. [

Each of the side plates 14 is formed with a hole 19 communicating therewith so that a pressure slider 40 for pressing and fixing the rocker 30 passes through the hole 19.

A hinge hole 21 communicating with each other is formed in the side plates 14 and the locker 30 is inserted into the space portion 16 between the side plates 14 as the hinge hole 21 A rivet 36 for rotatably connecting and fixing is inserted.

The locker 30 is engaged with the rivet 36 in a state where the locker 30 is fitted in the space 16 of the main body 10 and rotates about the rivet 36, 14 for pressing and fixing the pipe P that is seated in the groove portion 18. [

The rocker 30 is formed in a "⊃" cross-sectional shape, and holes are formed in both sides of the rocker 30, and the shaft pin is inserted into the hole.

At the upper end of the rocker 30, a finger ring 34 is extended. The fingers 34 are inserted into the pipe P positioned in the groove 18 formed at the upper end of the main body 10 in the process of rotating the locker 30 from the rivet 36 And the pipe P is fixed so as not to be detached from the groove portion 18 of the main body 10.

It is preferable that the front surface of the finger ring 34 is rounded so as to form a concave portion R so that the concave portion R can be easily attached to the outer diameter of the frame P. [

A protruding surface portion (32) protrudes from the front surface of the rocker (30). The protruded surface portion 32 is pressed in a wedge manner through the tilt angle of the tapered portion in accordance with the sliding operation of the pressing slider 40 in a state of being in contact with the tapered portion 42 formed on one side of the pressing slider 40, The fingers 36 of the rocker 30 are rotated by the rotation of the locker 30 around the rivet 36 so that the outer diameter of the pipe P, which is positioned in the groove 18 of the main body 10, And the pipe P is fixed so as not to be detached from the groove 18 of the main body 10. [

The pressing slider 40 is slidably fitted in a hole 19 formed in both side plates 14 of the main body 10 and rotates the locker 30 in a wedge manner to move the pipe P To be fixed to the main body (10).

The pressing slider 40 is formed into a rod type having a predetermined length, and a tapered portion 42 is formed on one side surface thereof. The tapered portion 42 of the pressing slider 40 is acted to strike the tip of the pressing slider 40 from the outside in a state of being in contact with the projecting surface portion 32 formed on the front surface of the locker 30 When the pressing slider 40 is slidably moved, the protruding surface portion 32 is gradually pressed in a wedge manner to rotate the locker 30 from the rivet 36 so that the fingers 36 of the locker 30 are rotated So that the outer diameter of the pipe P positioned in the groove portion 18 of the pipe 10 is pressed.

That is, the wedge-type pipe clamp of the present invention configured as described above can implement the clamping operation only by hitting the pressing slider 40 in a wedge-like manner. Hereinafter, the clamping operation of the clamp 100 will be described .
