Description

Tee clamp for scaffolding fixation {T TYPE CLAMP FOR FIXING SCAFFOLD}

The present invention relates to a clamp for fixing a scaffold having a circular rod shape, and more particularly, to a T-type clamp (hereinafter referred to as a "tee type") which improves safety by increasing a clamping force.

In general, in order to prevent safety accidents and to prevent dust from spreading at construction sites, scaffolds are installed outside, and nets or barriers are used around the installed scaffolds. By the way, when the scaffolding is in the form of a tee when the scaffold is installed, the scaffold was fixed by electricity or arc welding to prevent the scaffold from shaking. However, this method has a problem in that the scaffolding effect is excellent but the work efficiency is low.

In order to solve the above problems, Korean patent application 1997-020626 (application number) discloses a scaffolding clamp that is easy to install.

1A and 1B are a perspective view and a cross-sectional view of the clamp disclosed in the above domestic patent application 1997-020626.

As shown in FIGS. 1A and 1B, a conventional clamp includes two sets of first tightening rings 10 connected by hinges 12 and two sets of attaching to first tightening rings 10, respectively. It has the 2nd tightening ring 20, the connection piece 14 extended in the 1st tightening ring 10, and the auxiliary connection piece 24 extended in the 2nd tightening ring 20. As shown in FIG.

With this structure, the vertical scaffold is placed at 16 in FIG. 1A and the horizontal scaffold is placed at 22, then closed as shown in FIG. 1B and secured with bolt 30 and nut 40.

By the way, the clamp described above has a problem that the fixing force is lowered because the scaffold is fixed with only one bolt. In addition, the contact area between the scaffold and the clamp is a flat surface, and when the scaffold is shaken by external force (wind, attraction, etc.), the vertical scaffold flows up and down, and the horizontal scaffold has the fastening ring 20 open to the left and the scaffold easily falls out. There is a problem.

In general, accidents occurring at the construction site are mostly safety accidents caused by inadvertent operator or equipment defects, and the above-described scaffolding fixing method may cause safety accidents, and may be caused by time and cost. There is a problem that causes loss of phosphorus.

In order to solve the above problems, an object of the present invention is to provide an excellent clamping force that can minimize the departure of the scaffold or flow occurs even if an external force is applied to the scaffold.

1A and 1B show a conventional T-type clamp.

2 is an exploded perspective view of the T-type clamp according to the embodiment of the present invention.

3 is a fastening state diagram of the T-type clamp according to the embodiment of the present invention.

The present invention for achieving the above object, has a structure divided into two horizontal (T) -shaped tubular body, a plurality of jagged protrusions are formed along the inner circumference of the inner surface, the corner portion and the opposite portion of the corner portion Brackets are formed to extend, and fastening holes are formed on the respective brackets, and the first and second clamp plates with screws formed on the outer circumferential surface of the portion accommodating the end portions of the scaffold, and the outer circumferential surfaces of the portion accommodating the ends. And a reinforcing ring formed on an inner circumferential surface of the screw to engage with the screw, and a bolt and a nut inserted into and fastened to the fastening holes on the respective brackets.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. In the following description, numerous specific details, such as specific configurations, are shown, which are provided to assist in a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those who have. And in describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

Figure 2 is an exploded perspective view of the T-type clamp according to the present invention, Figure 3 is a fastening state diagram of the T-type clamp according to the present invention.

As shown in the drawings, the present invention includes first and second clamp plates 10 and 10 'having a horizontally divided shape of a T-shaped tube, and the first and second clamp plates 10 and 10'. Is coupled to the reinforcing ring 30 for tightening the end of the portion in which the lateral scaffold (B in Fig. 3) of the clamp plates 10, 10 'is received, and the first and second clad plates 10, 10 ') is provided with bolts (11, 12, 13) and nuts (11', 12, '13') for firmly coupling both bodies.

Specifically, each of the first and second clamp plates 10 and 10 'is formed with a plurality of serrated protrusions along the inner circumference of the inner surfaces 40 and 40', and the brackets 17, 18, 17 ', 18' are extended, and opposite brackets 19, 19 'are formed opposite the brackets 17, 18, 17', 18 'of the corner portions. And on each bracket 17, 18, 19, 17 ', 18', 19 ', fastening holes 14, 15, 16, 14', 15, '16' through which the bolts 11, 12, 13 pass. ) Is formed.

In addition, an end portion of the portion in which the lateral scaffold (B in FIG. 3) is accommodated is formed with outer peripheral thread surfaces 20 and 20 'of a predetermined width on the outer surface thereof, and the outer peripheral surface of the reinforcing ring 30 is formed on the inner peripheral surface thereof. An inner circumferential threaded surface 31 that is coupled to the slopes 20 and 20 'is formed to enable engagement of the reinforcement ring 30. In addition, a plurality of protrusions 32 are formed on the outer circumferential surface of the reinforcing ring 30 to facilitate coupling of the reinforcing ring.

The present invention configured as described above is used to join the ends of the lateral scaffold (B of FIG. 3) perpendicular to the longitudinally installed scaffold (A of FIG. 3), and the process of combining both scaffolds at this time. Looking at it as follows.

First, the reinforcing ring 30 is inserted at the end of the lateral scaffold (B in Fig. 3), and the body of the longitudinal scaffold (A in Fig. 3) and the lateral scaffold (B in Fig. 3) are inserted. An end portion is wrapped up and down (or left and right) with the first and second clamp plates 10 and 10 '. Then, the three bolts 11, 12, 13 are inserted through the respective fastening holes 14, 14 ', 15, 15', 16, 16 ', and then three nuts 11', 12 ', 13' ) And the first and second clamp plates 10 and 10 'are tightly fixed to each other to be coupled in the form of a T-shaped tube.

Then, clamping ends of the lateral scaffold (B of FIG. 3) wrapped with a reinforcing ring 30 previously inserted into the lateral scaffold (B of FIG. 3) are tightened and screwed (FIG. 3). Reference).

By such fixing, the body of the longitudinally installed scaffold (A in FIG. 3) and the end of the adjacent scaffold (B in FIG. 3) are vertically coupled, and each scaffold (A, B in FIG. 3) is vertically coupled. The outer circumferential surface is not only firmly fixed by the projections 40 and 40 'of the inner surfaces of each clamp plate 10 and 10' that are pressed, but also in the case of the lateral scaffolding (B in FIG. Since it is more firmly fixed by (30), even if the entire scaffold is twisted, the scaffold B will not be separated.

On the other hand, the present invention described above has been described with respect to specific embodiments, of course, various modifications are possible without departing from the scope of the present invention. That is, the present invention is not limited to the above-described embodiments and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
