Construction Method of Grouting at the Top of Structural Column

Abstract

The invention belongs to the technical field of constructional column construction for buildings and particularly relates to a constructional column top pouring construction method. To make the top of a constructional column be tightly connected with the bottom of a beam and sufficiently play the aseismic effect of the constructional column, the constructional column top pouring construction method is provided. The construction method comprises the steps that after concrete beam and slab steel bars and formworks are installed and before concrete is poured, galvanized steel pipes communicating with the top end of the constructional column are embedded in a positioned mode, and when concrete of the constructional column is poured till the bottom of a concrete beam cannot be compactly filled, pouring is conducted through the embedded galvanized steel pipes. The effect that the top of the constructional column is tightly connected with the bottom of the beam is guaranteed, the construction quality of an infilled wall is improved, and original constructional column construction technique procedures are not changed. The number of the embedded galvanized steel pipes is no less than two, one embedded steel pipe can serve as an ichor pipe while pouring, and the effect that the top is sufficiently poured is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction of structural columns for buildings, and in particular relates to a construction method for grouting at the top of structural columns. Background technique [0002] Structural column is a concrete column made in the specified part of the masonry building wall according to the structural reinforcement, and according to the construction sequence of building the wall first and then pouring the concrete column. The structural column mainly does not bear the vertical load, but resists the impact. Shear, seismic and other lateral loads. During construction, the structural columns shall be poured integrally with the ring beams, ground beams and foundation beams. However, the top concrete of the traditional structural column is supported by bell mouth formwork. Due to the limitation of technology and operating conditions, it is difficult to ensure that the top concrete is poured densely, and forms a...

AI Technical Summary

Problems solved by technology

However, the concrete at the top of the traditional structural column is supported by bell-shaped formwork. Due to the limitations of the process and operating conditions, it is difficult to ensure that the concrete on the top is poured densely, and forms a gap layer with the bottom of the beam, which reduces the seismic effect.
