A protection fence for foundation pit of house construction

Abstract

The invention relates to a protective fence for a foundation pit in house construction, which includes a protective fence body. The protective fence body includes a base, a cross bar and two vertical bars parallel to each other. The two vertical bars are vertically connected to the base, and the horizontal bar is far away from the One end of the base is vertically connected to the vertical bar, and the base is fixedly connected to the ground. The area surrounded by the base, the horizontal bar and the two vertical bars is provided with an anti-fall arresting net. The rod is connected to the vertical rod, and the pull rope is rotated and wound on the base, the horizontal rod and the vertical rod respectively. When the connection with the anti-fall arresting net is far away from the guardrail body, the anti-fall arresting net and the guardrail body form an anti-fall space. The invention has the effect of effectively preventing personnel and vehicles from falling into the 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
