Tall and big factory building concrete column anti-collision angle steel embedding reinforcement method

Abstract

The invention discloses a tall and big factory building concrete column anti-collision angle steel embedding reinforcement method which is characterized by including the steps: a forming through holesin positions, 100mm away from the top and the bottom of an anti-collision angle steel, of one edge of the anti-collision angle steel; b forming through holes matched with the anti-collision angle steel through holes in positions, corresponding to the through holes in one edge of the anti-collision angle steel, of a concrete column template; c providing through screws, enabling the through screwsto penetrate the through holes of the concrete column template and connecting the through screws with the through holes in one edge of the anti-collision angle steel; d detaching the template after concrete pouring and cutting off exposed through screws along the outer surface of the anti-collision angle steel. The method has the advantages that the anti-collision angle steel embedding reinforcement method is simple and clear, the angle steel and the template are reliably fixed, surface smoothness of the angle steel and a column after detachment of the template can be ensured as long as the template does not shift during concrete pouring, perception is excellent, and manpower and material consumption of secondary rework is omitted.

Description

technical field [0001] The invention relates to a method for embedding anti-collision angle steels, in particular to a pre-embedded reinforcement method for anti-collision angle steels of high and large columns of a factory building. Background technique [0002] The anti-collision angle steel is set at the external corners of pillars, walls, etc. to set angle steel or rubber corner guards. It is a protective measure adopted to prevent indoor forklifts from damaging the external corners of pillars, walls, etc. The section size of the structural column of the factory building is mostly 900x900mm, 1000x1000mm, and the height is 10.95m, which belongs to the pouring of tall columns. When the column is poured, due to the high column body, the concrete at the root must be fully vibrated and compacted to ensure the pouring quality. In the past, the anti-collision angle steel did not have good fixing measures when it was pre-embedded. It will inevitably be impacted by the concrete ...

AI Technical Summary

Problems solved by technology

In this technical scheme, although the setting of horizontal tie bars strengthens the connection strength between the angle steel and the stirrups, the formwork is supported outside the stirrup frame in the later period, and the operation of pouring concrete in the stirrups will still be affected by the concrete from above. The impact caused by the downward impact and the impact generated by the vibrating rod during the vibration caused local displacement, which caused the anti-collision angle steel and the column surface to be out of the same plane after the formwork was removed. Manpower, material resources, increase the situation of construction costs

[0004] Therefore there is above-mentioned inconvenience and problem in the pre-embedded mode of known anti-collision angle steel
