Abstract

The utility model discloses a scaffold fastener, which belongs to the construction field. It includes a buckle and a buckle end. The buckle is provided with a vertical bar hole, and the buckle end is provided with a horizontal bar hole. The side wall of the buckle is provided with buckle teeth. The wall is provided with a buckle groove matched with the buckle teeth. One end of the buckle groove has a large opening and the other end has a small opening, and the upper end of the buckle groove is closed. The application process of the utility model is as follows: the buckle ring is fixed on the vertical bar, and the buckle end is fixed on the cross bar. When building a scaffold, because the buckle teeth are small at the top and big at the bottom; The opening at the lower end is narrow, and after the buckle teeth and the buckle grooves are locked together, when the scaffold bears the weight, the end of the buckle will move downwards, making the combination of the buckle teeth and the buckle groove more stable, with better stability and less potential safety hazards , and easy installation, simple structure.

Description

A scaffold fastener

technical field

The utility model belongs to the construction field, and in particular relates to a construction scaffold fitting.

Background technique

In building construction, the installation of scaffolding is an indispensable project. At present, some fasteners for erecting scaffolding are fastened with bolts and nuts. This kind of structure is easy to slide when it is subjected to unloading vibration or natural loosening. The stability is not good, and the safety hazard is great. . Also have a kind of fastener as shown in the utility model patent that application number is " 200720095921.6 ", title is called " scaffold connection lock ", although this structure is high in stability, complex in structure, installation trouble.

Utility model content

The technical problem to be solved by the utility model is that the scaffold fastener has poor stability, complex structure and troublesome installation, and provides a scaffold fastener with good stability, simple structure and easy installation.

The technical scheme of the utility model is realized in the following manner:

A scaffold fastener, comprising a buckle and a buckle end, a vertical bar hole is arranged in the buckle ring, a cross bar hole is arranged in the buckle end, buckle teeth are arranged on the side wall of the buckle ring, one end of the buckle tooth is smaller and the other end Large, the side wall of the buckle end is provided with a buckle groove matched with the buckle teeth, one end of the buckle groove has a large opening, and the other end has a small opening, and the upper end of the buckle groove is closed.

There are teeth on each side of the clasp.

The application process of the utility model is as follows: the buckle ring is fixed on the vertical bar, and the buckle end is fixed on the cross bar. When building a scaffold, because the buckle teeth are small at the top and big at the bottom; The opening at the lower end is narrow, and after the buckle teeth and the buckle grooves are locked together, when the scaffold bears the weight, the end of the buckle will move downwards, making the combination of the buckle teeth and the buckle groove more stable, with better stability and less potential safety hazards , and easy installation, simple structure. Because in the construction process, the cross bar may be fixed on all directions of the vertical bar, if each side wall of the buckle ring is provided with buckle teeth, it is more convenient for construction.

Detailed ways

Example 1

As shown in Figures 1 to 4, the utility model includes a buckle 1 and a buckle end 4. The buckle 1 is provided with a vertical bar hole 3, and the buckle end 4 is provided with a cross bar hole 6. The side of the buckle 1 is The wall is provided with buckle teeth 2, one end of the buckle teeth 2 is small and the other end is large (as shown in Figure 2, the top is small and the bottom is large), the side wall of the buckle end 4 is provided with a buckle groove 5 matched with the buckle teeth 2, the buckle groove 5 One end opening is large, and one end opening is small (as shown in Figure 4, the upper end opening is large, the lower end opening is small), and the upper end of the buckle groove 5 is a closed type (the closed type means that the structure of the buckle groove 5 is similar to a blind hole, and the buckle groove 5 is closed. does not run through the entire sidewall).

The cross section of the clasp 1 and the clasp end 4 is quadrilateral. Or the cross section of the buckle 1 and the buckle end 4 is pentagonal, hexagonal, octagonal or other. Since the cross section of the buckle 1 and the buckle end 4 are consistent, the side where the buckle tooth 2 is located and the side where the buckle groove 5 is located can cooperate well during assembly, and the stability is better. And the buckle groove 5 does not run through the side wall of the buckle end 4, even if the scaffolding is subject to greater pressure, because the buckle groove 5 wide mouth end is closed, the cross bar and the vertical bar can be well fixed together, and the safety hazard is relatively large. few.

Example 2

One or two or three side walls of the buckle 1 are provided with buckles 2, and the others are the same as in the first embodiment.

Claims (3)
