Anti-falling safety net

Abstract

The invention relates to a safety device for architectural engineering construction, in particular to an anti-falling safety net. The traditional anti-falling net needs to use a great number of steel pipes with heavy weight, and large-scale horizontal and perpendicular transportation equipment is needed to install the traditional anti-falling net; safety can not be ensured during erection, and the time for the erection is long; and when a falling object is too large, a hanging steel pipe support is easily pulled to deform. The invention relates to an anti-falling safety net which comprises a net frame, wherein the net frame is connected with a building, and the net frame comprises trusses; the trusses are connected with a building structure, and the anti-falling net is arranged between the trusses; connecting steel plates are installed at the inner ends of the trusses, and are fixed on the building structure through connecting pieces; and a steel wire rope threading ring I is arranged at the outer end of each truss, and is connected to a pulley at the outer end of a corner truss by penetrating through a steel wire rope threading ring. The invention has the advantages of material saving, light weight, local material usage, capability of repeated usage by stereotyping, convenience for installation and reliability in fixing.

1. Technical field: [0001] The invention relates to a safety device for construction engineering, in particular to a safety device for preventing falling [0002] Nets are mainly used in the design, installation and support of horizontal protective nets in construction projects. 2. Background technology: [0003] Building construction is a high-risk industry, and the height of buildings is getting higher and higher. The setting of horizontal protective nets is one of the important measures to ensure construction safety. There are many ways to set up conventional horizontal protective net supports, one of which is to use several vertical and horizontal single steel pipes to form a A larger planar net frame, the distance between the steel pipes is about 400 mm in one direction and about 1 meter in the other direction, and then a horizontal safety net is laid on the net frame, and the fixed end of the net frame is fixed on the structure with fasteners, bolts, etc. , one end of...

[0003] Building construction is a high-risk industry, and the height of buildings is getting higher and higher. The setting of horizontal protective nets is one of the important measures to ensure construction safety. There are many ways to set up conventional horizontal protective net supports, one of which is to use several vertical and horizontal single steel pipes to form a A larger planar net frame, the distance between the steel pipes is about 400 mm in one direction and about 1 meter in the other direction, and then a horizontal safety net is laid on the net frame, and the fixed end of the net frame is fixed on the structure with fasteners, bolts, etc. , one end of the cantilever is fixed on the structure with a wire rope. The disadvantage of this method is that it occupies a large number of steel pipes and is heavy. It needs to be installed with large horizontal and vertical transportation equipment (such as tower cranes), which is not safe enough and takes a long time to erect. One is to set up a tapered cantilevered steel pipe support at the corner of the structure, and the root of the steel pipe support is fixed on the structure with a top brace, and then the outer steel wire rope is erected at the cantilevered far end of the cantilevered steel pipe support and the bolt hole setting is used when the structure supports the formwork. The inner steel wire rope fixes the horizontal safety net on the steel wire rope and the straight support of the cantilevered jumping steel pipe respectively. The disadvantage of this method is that it is not safe to erect the cantilevered steel pipe support. The distance between the two supports is completely controlled by the shape of the building’s facade. When the falling object is large, it is easy to deform the cantilevered steel pipe support
