Single-layer attachable climbing and outward-lifting protective device and construction method thereof

Abstract

The invention relates to a single-layer attachable climbing and outward-lifting protective device. The single-layer attachable climbing and outward-lifting protective device comprises an anchoring screw and positioning supporting seats, an upper set of positioning supporting seat and a lower set of positioning supporting seat are arranged, and clamping grooves are formed in the head parts of eachpositioning supporting seat. A climbing device comprises vertical arm rods clamped in the clamping grooves and connecting lug plates which are welded on the upper and lower positions of the vertical arm rods, and the vertical arm rods and the positioning supporting seats are connected in a hinged mode. Movable clamping rings are arranged at the two ends of connecting pipes in a sleeving mode. Thefour connecting pipes with the movable clamping rings are connected to form a rectangular frame, and a safety net is laid on the rectangular frame. One ends of wire ropes are connected with the connecting lug plates which are located at the upper ends of the vertical arm rods, and the other ends of the wire ropes are connected with the one side of the rectangular frame by the movable clamping rings. The other side of the rectangular frame is connected with the connecting lug plates which are located at the lower ends of the vertical arm rods. The ingle-layer attachable climbing and outward-lifting protective device can be pre-fabricated as a whole on the ground, the safety process is programmed and simplified, standardized construction is facilitated, and the outward-lifting net device canbe directly lifted and climbed by inverted chains and tower cranes.

Description

technical field [0001] The invention relates to a device related to a safety net used in construction, in particular to a single-layer attachment climbing type overhang protection device and a construction method thereof. The utility model belongs to the technical field of building steel structures. Background technique [0002] With the development of the domestic construction industry, there are more and more high-rise and super high-rise buildings. High-rise and super high-rise buildings are surrounded by high-altitude air-facing surfaces. There are safety hazards of falling from high altitudes and falling objects. The protection work of high-altitude safety is very important. In order to ensure construction safety and create a safe working environment, external protective devices came into being. [0003] Existing overhanging protective devices usually include an overhanging net frame, a zip rope for fixing the overhanging net frame and a safety net laid on the overhang...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the conventionally used overhanging net is that its frame needs to be installed on the high-altitude floor of the building, the safety procedures are complicated and cumbersome, and the safety is difficult and risky

Furthermore, the fasteners have problems such as insufficient wall thickness, sand holes, cracks, etc., and there are potential safety hazards

At the same time, after the construction of the corresponding floors is completed, the outer frame device needs to be disassembled, and the upper floor to be transferred is reinstalled, resulting in a lot of repetitive work
