Construction method of a reinforced concrete composite slanted column

Abstract

The invention discloses a construction method for a reinforced concrete composite slanted column, which comprises the following steps: (1) construction preparation; (2) slanted column positioning and reinforcement insertion; (3) erection of a steel pipe support at the bottom of the slanted column and laying of a formwork for the lower section of the slanted column; (4) Reinforcement installation; (5) PVC chute setting; (6) Reinforcement of lower slanted column formwork; (7) Concrete trial mix; (8) Lower slanted column concrete pouring; (9) Lower slanted column side form removal; (10) ) Construction of the upper inclined column: the construction process of the upper inclined column is the same as that of the lower inclined column, and steps (2) to (9) are repeated. In the case that the inclined column concrete is not easy to vibrate, the mixing ratio of the concrete is optimized, the slump of the concrete is adjusted, and the chute is used to assist the vibration when the concrete is vibrated, so that the reinforced concrete structure of the inclined column is formed well.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete construction, and in particular relates to a construction method of a reinforced concrete composite inclined column. Background technique [0002] At present, "National Fitness" has become an indispensable part of our people's daily life. The construction of a large number of sports venues has emerged as the times require. On the premise of meeting the requirements of building functions, more and more sports arenas with beautiful shapes and various forms Such buildings have sprung up like mushrooms after rain. During the construction phase of the main structure of the stadium, there are often cases where the reinforcement of the reinforced concrete slanted column formwork is not firm, the joints do not meet the requirements, and the concrete vibration is not in place, resulting in concrete expansion, grout leakage, honeycomb, pitting and other phenomena. If the corresponding measures ...

AI Technical Summary

Problems solved by technology

In the construction stage of the main structure of the stadium, there are often cases where the reinforcement of the reinforced concrete slanted column formwork is not firm, the joints do not meet the requirements, and the concrete vibration is not in place, resulting in concrete expansion, grout leakage, honeycomb, pitting, etc.

If the corresponding measures are not taken in time, the size and bearing capacity of the cast-in-place structure of the reinforced concrete slanted column will not meet the specification requirements, which will eventually cause economic losses, quality accidents, and safety accidents.
