[0002] The general method of connecting steel pipes is to connect one layer at a time, so as to ensure that the concrete inside and outside the steel pipe is poured at the same time. If the method of connecting one layer at a time is used, the steel pipe must be cut off on site and then connected to a higher level, but the amount of inner liner pipe and welding will be increased. The number of times, and the high position of the steel pipe cannot be set in the core area of ​​the beam and column, and some steel pipes must not be used, which will greatly increase the cost and the construction period will also greatly increase

Embodiment Construction

[0033] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] The construction method of steel tube concrete composite column includes the following steps:

[0035] Step 1, construction preparation;

[0036] Step 2, temporarily fix the steel pipe column;

[0037] Step 3, connect and fix the steel pipe column;

[0038] Step 4, the outer frame beams are bound with steel bars and the formwork is supported;

[0039] Step five, concrete pouring of the steel pipe concrete composite column.

[0040] Step 1. During construction preparation, according to the design and specification requirements, the height connection position of steel pipes is usually between 0.3-1m above the floor. After each steel pipe enters the site, carry out actual measurement, and make reasonable arrangements to ensure the correct height connection position; each steel pipe is numbered Finally, according to the i...

Abstract

The invention discloses a construction method for steel tube confined concrete composite columns. The construction method comprises the following steps: step 1, construction preparation; step 2, temporarily fixing steel tube columns; step 3, connecting and fixing steel tube columns; step 4, assembling rebars on an outer frame girder and arranging formworks in a supporting manner; step 5, concrete-pouring the steel tube confined concrete composite columns. According to the invention, steel tube columns in multiple floors are connected, the hoisting frequency of a tower crane is reduced, and the amount of inner lining pipes and the times for welding steel tubes are reduced, so that the construction method has the advantages that the construction period is shortened and the cost is reduced.

Description

technical field [0001] The invention relates to a construction method of a steel pipe concrete composite column. Background technique [0002] The general method of connecting steel pipes is to connect one layer at a time, so as to ensure that the concrete inside and outside the steel pipe is poured at the same time. If the method of connecting one layer at a time is used, the steel pipe must be cut off on site and then connected to a higher level, but the amount of inner liner pipe and welding will be increased. The number of times, and the high position of the steel pipe cannot be set in the core area of ​​the beam and column, and some steel pipes must not be used, which will greatly increase the cost and the construction period. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method of steel pipe concrete composite column. The steel pipe column adopts multi-layer joint connection, which reduces ...
