Foundation pit protection fence for house building construction

Abstract

The invention relates to a foundation pit protection fence for house building construction. The foundation pit protection fence comprises a protection fence body. The protection fence body comprises abase, a transverse rod and two vertical rods which are parallel to each other. The two vertical rods are perpendicularly connected to the base. The ends, away from the base, of the transverse rod areperpendicularly connected with the vertical rods. The base is fixedly connected to the ground, and a falling-preventing blocking net is arranged in the area defined by the base, the transverse rod and the two vertical rods. The falling-preventing blocking net is connected with the base, the transverse rod and the vertical rods through multiple pulling ropes. The pulling ropes are rotationally wound around the base, the transverse rod and the vertical rods. When the connecting positions of the pulling ropes and the falling-preventing blocking net are close to the protection fence body, the falling-preventing blocking net is attached to the protection fence body, and when the connecting positions of the pulling ropes and the falling-preventing blocking net are away from the protection fencebody, a falling-preventing space is formed by the falling-preventing blocking net and the protection fence body. The foundation pit protection fence has the beneficial effect that personnel and vehicles are prevented from falling into a foundation pit.

Description

technical field [0001] The invention relates to the technical field of foundation pit protection, in particular to a foundation pit protection fence for house construction. Background technique [0002] At present, protective fences are generally installed around the foundation pit of housing construction to serve as a reminder to prevent people and vehicles from entering the construction area of ​​the foundation pit by mistake and causing the danger of falling. [0003] In the existing technology, the Chinese patent with the authorized publication number CN107829565A discloses a protective fence for a construction site, which includes two uprights, and the inside of the two uprights is longitudinally provided with a chute, and a plurality of sliders are arranged in the chute. A sleeve is connected to the side of the slider on one side, and a sleeve rod is arranged inside the sleeve. Positioning pins are arranged inside, the bottom end of the upright column on one side is f...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the columns can be placed on the concrete ground, although the energy required for installing the guardrails is saved, and the construction personnel can directly remove the guardrails when they need to go in and out of a certain place; The impact resistance of the guardrail is poor. When pedestrians or vehicles accidentally hit the guardrail, the guardrail will easily fall down. When colliding with the barriers, the vehicle may break through the protective barrier, causing the vehicle to fall into the foundation pit, resulting in a major traffic accident
