Abstract

The invention discloses an anti-aging reinforcing structure for a building construction foundation. The structure comprises a counter bored hole structure arranged on a construction face and an inner layer reinforcement cage arranged inside the counter bored hole structure. The inner layer reinforcement cage is sleeved with a middle reinforcement cage. The middle reinforcement cage is sleeved with an outer layer reinforcement cage. The inner layer reinforcement cage is as high as the middle reinforcement cage and the outer layer reinforcement cage. Due to the fact that a compound plasticizer composed of di-iso-decylphthalate, beta-diketone and ammonium polyphosphate is added to be matched with polyethylene resin, the forward effect of the plasticizer is maximized, the mechanical property is improved, the aging resistance and the machining performance are improved, flexibility is improved, meanwhile, ammonium polyphosphate has the effect of a condensed phase, and the good flame retardant effect is achieved with the combination of ammonium polyphosphate and magnesium hydroxide; due to the addition of hexadecyl dimethyl amine, the good antistatic effect is achieved. Surplus gas or liquid circulation is achieved on the inner side of a concrete column, and local damage is avoided.

Description

technical field [0001] The invention relates to an anti-aging reinforcement structure for a building construction foundation. Background technique [0002] The supporting column structures used in underground parking lots and other places usually need to have high strength, be able to withstand large pressure and shear force, and not be easily damaged. The existing column structure usually only adopts the method of pouring concrete with a steel cage, which has a simple structure and is easily damaged when subjected to external force impacts and other conditions, and has a limited service life. Contents of the invention [0003] The purpose of the present invention is to provide an anti-aging reinforcement structure and reinforcement method for building construction foundations, which can improve the problems existing in the prior art. By adopting an inner and outer three-layer steel cage structure, the strength of the overall structure can be effectively improved. At the s...
