Overhead protection method

Abstract

The invention discloses an overhead protection method. The overhead protection method comprises the following steps: step 1, vertical and horizontal main steel wire ropes are erected above a bottom plate to be subjected to demolition blasting; step 2, double dense expanded steel mesh layers are laid on the main steel wire ropes; step 2, a single bamboo sheathing layer is laid fully on the double dense expanded steel mesh layers; step 4, safety dense meshes are fully laid on the single bamboo sheathing layer; step 5, the surface of the safety dense meshes is covered with a canvas layer. According to the method, the vertical and horizontal main steel wire ropes are erected above the bottom plate to be subjected to demolition blasting, by means of the principle of repeated energy absorption from swinging of the steel wire ropes, the main steel wire ropes are matched with the double dense expanded steel mesh layers on the main steel wire ropes, the bamboo sheathing and the safety dense meshes are laid on the double dense expanded steel mesh layers, dustproof canvas is used for covering finally, then the overhead safety protection frame is formed, and flying stone and dust generated in blasting of the bottom plate can be blocked effectively. Repeated and continuous blasting can be implemented with the overhead protection method, the construction cost is low, and the materials used in the method all have the characteristics of recyclability and low probability of loss.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an overhead protection method. Background technique [0002] In my country, with the development of the economy, due to the adjustment of building functions, the displacement of the plane position of high-rise buildings and the increase of floors, the upper load increases. Some basic plans have been readjusted. This has also brought a series of problems such as technological transformation such as floor demolition blasting, especially in the construction of floor demolition blasting, multiple continuous blasting is required, so how to ensure safety protection in multiple continuous blasting, the prior art adopts The best measure is to repeatedly set up and dismantle the floor-to-ceiling protective sheds for protection when the bottom plate is repeatedly blasted, resulting in high construction costs and large material loss. Contents of the invention [0003] The present inv...
