Described magnetic pre-embedded steel slab is through magnetized steel plate, and thickness is 20mm.
The present invention installs and uses in the following way:
The first step: lacing wire is welded with magnetic pre-embedded steel slab;
Second step: binding structure steel mesh reinforcement, according to roughly locating, to adopt thin galvanized wire to be temporarily fixed on structure reinforcing bars magnetic pre-embedded steel slab online;
3rd step: vertical steel form, and according to project organization size, measurement and positioning is carried out and fixing steel form to steel form;
4th step: remove the temporary fixed galvanized wire of magnetic pre-embedded steel slab, magnetic pre-embedded steel slab is adsorbed in steel form surface, measurement and positioning magnetic pre-embedded steel slab position also adjusts location again again;
5th step: install fixed magnetic pole to the steel form back side of magnetic pre-embedded steel slab correspondence position, review and validate magnetic pre-embedded steel slab firm stable;
6th step: pouring structure concrete;
7th step: reach after design strength until structural concrete, removes steel form, is cleaned out by magnetic pre-embedded steel slab surface and oil contaminant;
8th step: steel work is connected by welding on magnetic pre-embedded steel slab.
Beneficial effect of the present invention is: pre-embedded steel slab is tightly adsorbed in steel form surface by utilizing magnetic, and strengthen the absorption affinity between pre-embedded steel slab and steel form further by fixed magnetic pole, pre-embedded steel slab is avoided to produce displacement in concrete vibrating work progress, and install simple and convenient, accurate positioning, avoiding prior art needs artificial chisel to remove the concrete operation of surface of steel plate; Further, after manually cutting pre-embedded steel slab surface concrete under prior art, pre-embedded steel slab surface will be inconsistent with concrete surface planeness, cause difficulty to later stage welding for steel structure, will avoid the generation of this problem after adopting the present invention.
