Description

Scaffolding Pipe Clamps

The present invention relates to a clamp for scaffolding pipe coupling, and more particularly, to a scaffolding pipe coupling clamp that can improve workability by simply mounting and fastening the scaffolding pipe at various construction sites.

Generally, scaffolds for scaffold pipe joining are originally mounted on scaffold columns installed to work at high places in construction work. : It is used to weave joist) and poles in a grid. Since this coupling must maintain a significant coupling strength for the purpose of preventing personnel accidents or safety accidents in the construction work, it is usually adopted a metal material and attempts to join by tightening fastening means, for example, bolts and nuts. Doing.

The scaffold pipe coupling clamp according to the related art which performs the above function will be described with reference to the illustrated drawings.

Reference numeral 100 in the figure indicates a scaffolding pipe.

Conventional scaffold pipe coupling clamps for fixing the scaffold pipe 100 include a first body 10 having a first bolt 11, a first nut 12, and a pair of first bent surfaces 14. ) And the second body 20 having the second bolt 21, the second nut 22, and the second bent surface 24 are rotatably coupled to each other, and the first body 10. In the first groove 31 and the first cover 30 consisting of a pair of first attachment wings 34, 36 are hinged and at the same time the second body 20 has a second groove 41 and A second cover 40 consisting of a pair of second attachment wings 44 and 46 is hinged.

In the conventional scaffold pipe coupling clamp having such a configuration, when the scaffold pipe 100 is to be fastened, the scaffold pipe 100 is inserted into the first and second body parts 10 and 20. After the first and the second cover 30, 40 is wrapped in the form surrounding the scaffolding pipe 100, the first, second, 30, 40, which are located on both sides of the Two attachment wings 34, 36, 44, 46 are tightly coupled to the outer circumferential surface of the scaffold pipe 100.

By the way, the conventional clamp for scaffold pipes of such a structure has the following problems.

First, as shown in FIG. 2, when the cover of the clamp coupled with the scaffold pipe is opened, there is no fixing device that can be fixed in the middle of the cover part. Since the clamp may fall off from the cover of the clamp in the direction of the arrow, the worker has to work while supporting the scaffolding pipe.

Second, as shown in FIG. 1, since the bent surface formed on the body of the clamp is rounded to one surface of the shape of a concave ellipse, the contact surface with the scaffold pipe is widened when the scaffold pipe is fastened and the tightening force is weakened or slippage occurs. This occurred and had the problem that the cohesion fell.

Accordingly, the present invention has been made to solve the above problems, the purpose is to improve the shape when assembling or fastening the scaffolding pipe in various construction sites to improve the workability by high coupling strength and simple mounting It is possible to provide a clamp for scaffolding pipe coupling that can strengthen the binding force.

Scaffolding pipe coupling clamp according to the present invention for achieving the above object, the first body having at least a first bolt, a first nut and a pair of first bent surface, a second bolt, a second nut and a A second body having a pair of second bent surfaces is coupled to each other to enable mutual rotational movement, and at the same time, the first and second bodies comprising first and second grooves and a pair of adhesive wings on the first and second bodies. A scaffolding pipe coupling clamp configured to be hinged to each other, the clamp having a first and a second step formed in the inner side of the first and second bent surfaces, and each engaging jaw formed at one end of the first and second cover. It consists of 1 and a 2nd stopper.

Hereinafter, with reference to the accompanying drawings for the scaffolding pipe coupling clamp according to the present invention. For the sake of simplicity, the same reference numerals are used for the same parts as the conventional description to avoid descriptive clutter.

Figure 4 is a fastening state diagram showing a clamp according to the present invention, Figure 5 is a perspective view showing the body portion of the clamp according to the present invention, Figure 6 (a) is a cross-sectional view showing a cover of the clamp according to the present invention, 6 (b) Figure 7 is a bottom view showing the cover of the clamp according to the present invention, Figure 7 is a fastening state diagram of the clamp for scaffolding pipe according to the present invention.

First, as shown in FIG. 4 and FIG. 5, the pair of first bends 16 are connected to the pair of first bent surfaces 14 and the pair of second bent surfaces 24 are not limited thereto. The pair of second steps 26 are formed to face each other. The first and second steps 16 and 26 are bent in a concave oval shape so that the outer surfaces of the first and second bent surfaces 14 and 24 naturally protrude, and the first body 10 ) Is formed in the first cover 30 and the second body 20 so that the second cover 40 is hinged to face each other.

And as shown in FIG. 6 (a) and FIG. 6 (b), when the said 1st, 2nd cover 30 and 40 rotate and open, respectively, the said 1st, 2nd in a desired fixing point First and second stoppers 32 and 42 are formed to cover the covers 30 and 40, respectively. The first stopper 32 is formed to be securely caught by being in close contact with the body end 18 formed at the end of the first body 10 by the first catching jaw 32a, and the second stopper ( The second catching jaw 42a is formed at 42 so as to be fixed in line with the body end 28 formed at the end of the second body 20.

With reference to the accompanying drawings, the operation and operation of the scaffolding pipe coupling clamp according to the present invention configured as described above will be described in more detail.

4 and 5, the clamp for scaffolding pipe according to the present invention includes a first step 16 formed on the first bent surface 14 of the first body 10, and a second body 20. Even if the second step 26 formed at the second bent surface 24 of the c) is small in cross section contacting the scaffolding pipe 100 and tightened with the same tightening force, a much larger stable fastening force can be obtained.

That is, when the tensile load is applied to the scaffold pipe 100 during construction work in the state in which the scaffold pipe 100 and the clamp of the present invention are fastened, and the tensile load is received by arrows X and Y (see FIG. 7), the scaffolding Since the clamp with the pipe 100 has a small contact cross section, the clamping force is increased to prevent slipping of the step.

As a result, as shown in the drawing, the scaffold pipe 100 is inserted into the first and second body parts 10 and 20, and then the first cover 30 and the second body 20 are inserted. The second cover 40 may be hinged to face each other to surround the scaffolding pipe 100 so as to more strongly prevent the sliding of both.

In addition, the first and second stoppers 32 and 42 have the first and second covers 30 at the desired fixing points when the first and second covers 30 and 40 are rotated and opened, respectively. The scaffolding pipe 100 is removed because the first and second bodies 10 and 20 are caught by the body ends 18 and 28 formed at the ends of the first and second bodies 10 and 20. 1, the second cover 30, 40 can be easily mounted on the first and second attachment wings 34, 36, 44, 46 formed concave inside the work. .

As described above, according to the clamp for the scaffolding pipe according to the present invention, even when subjected to a strong tensile load during construction work, because the step formed in the body serves to fasten the scaffolding pipe strongly, there is no sliding phenomenon, and also the cover The stopper installed on one side of the stopper is in close contact with the end of the body when the cover is open, so the cover is fixed horizontally so that the scaffolding pipe does not flow down so that the user can easily work on the scaffolding pipe.

Further, when the step formed on the outer surface of the bent surface while the first and second attachment wings of the body fit the pipe to tighten the scaffolding pipe, the clamping force of the clamp concentrates on the step provided on the bent surface of the body. There is an excellent effect that the tightening force is further improved.
