Description

A safety fence for a construction site

technical field

The utility model relates to the field of construction site auxiliary tools, in particular to a safety fence for the construction site.

Background technique

At present, setting up safety fences is one of the important technical measures to ensure the safety of construction site personnel and normal construction. In order to ensure smooth construction and avoid safety accidents caused by pedestrians entering the construction area by mistake, construction units generally isolate the construction area by installing safety fences.

Traditional safety fences are usually built on concrete piles at the construction site, and the columns of the fence are fixed on the concrete piles. This form of safety fence is a relatively fixed setting. People can see this kind of safety fence during the day. They may enter the construction area by mistake, but at night, due to the dark light, people cannot tell whether there is construction ahead, and it is easy to enter the construction site by mistake, which may cause some safety accidents. Therefore, it is necessary to install lights or warning lights on the safety fence. However, the lights or warning lights on the existing fence generally provide electric energy through the engine, which causes waste of resources and brings noise.

In addition, in order to facilitate the movement of the safety fence, the structure of installing rollers at the bottom of the fence is often used. However, because the rollers are easy to slide, the safety fence is easy to collapse on the construction site with uneven road surface. The staff need to allocate time to lift the fence, which affects the construction. efficiency.

To sum up, in the prior art, there is still no effective solution to the problem of how to design a more convenient construction site.

Detailed ways

It should be pointed out that the following detailed description is exemplary and intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It should be noted that the terminology used here is only for describing specific implementations, and is not intended to limit the exemplary implementations according to the present application. As used herein, unless the context clearly dictates otherwise, the singular is intended to include the plural, and it should also be understood that when the terms "comprising" and/or "comprising" are used in this specification, they mean There are features, steps, operations, means, components and/or combinations thereof.

As introduced in the background technology, there are deficiencies in the prior art that the safety fence cannot effectively serve as a warning and is prone to collapse. In order to solve the above technical problems, this application proposes a safety fence for construction sites.

In a typical implementation of the present application, as shown in Figures 1-3, a safety fence for a construction site is provided, including a plurality of fences, and adjacent fences are detachably connected by a plurality of rotating connecting frames 2 ; The number of fences depends on the area of the construction site.

Take the example of how two fences are connected:

As shown in Figure 1, the first fence 1 and the second fence 4 are connected by two rotating connecting frames 2, and a certain angle can be formed between the first fence 1 and the second fence 4 by rotating the connecting frames 2, It is convenient to use on the construction site.

The rotating connecting frame 2 includes a sleeve 6 and an L-shaped connecting frame 10; the end of the first fence 1 near the second fence 4 is provided with a sleeve 6, and the end far away from the second fence 4 is provided with an L-shaped connecting frame 10; The end of the second fence 4 close to the first fence 1 is provided with an L-shaped connecting frame 10 , and the end far away from the second fence 4 is provided with a sleeve 6 .

The L-shaped connecting frame 10 includes a vertical section parallel to the sleeve 6 and a parallel section fixed on the fence; the vertical section of the L-shaped connecting frame 10 is inserted into the sleeve 6 to realize the connection between the two fences.

The inner diameter of the sleeve 6 is larger than the diameter of the L-shaped connecting frame 10 .

The upper and lower ends of the first fence 1 and the second fence 4 are provided with solar LED lamps 3 respectively, and the solar LED lamps 3 are arranged in a transparent protective cover, and the transparent protective cover is clipped together with the fence.
