Reinforced concrete structure hollow thin wall pier type steel frame column and construction method thereof

Abstract

The invention provides a reinforced concrete structure hollow thin wall pier type steel frame column and a construction method. The main body of the reinforced concrete structure hollow thin wall pier type steel frame column is provided with four steel angles (1) arranged at the four corners of the column and batten plates (8) welded between the two adjacent steel angles in a spaced mode, wherein the upper ends of the steel angles are welded with an upper positioning steel plate (3), and the lower ends of the steel angles are welded with a lower positioning steel plate (2). The reinforced concrete structure hollow thin wall pier type steel frame column is characterized in that the lower positioning steel plate (2) and the upper positioning steel plate (3) are both rectangular, the geometric centers of the upper and lower positioning steel plates are both provided with central holes, the positioning steel plates are provided with four symmetrical positioning holes along two axes, steel rib positioning pins are matched with the positioning holes and can be inserted into the positioning holes, and hoop ribs (9) are welded around the four steel angles (1) in a spaced mode. The construction method is simple, low in manufacturing cost, and capable of effectively controlling the deviation of upper and lower segment shape steel frame column axes, the construction expense is reduced, the construction period is shortened, and the construction quality of the shape steel frame column is improved.

Description

technical field [0001] The invention belongs to the technical field of building steel components, and in particular relates to a hollow thin-walled pier-shaped steel skeleton column of a steel-concrete structure and a construction method thereof. Background technique [0002] Steel-concrete structures are widely used in various projects such as railways, highways, and municipal projects. During the construction of steel-concrete structures of concrete buildings (or structures), there are usually certain quality problems due to unreasonable pre-embedded steel components, weak combination of steel components and concrete, and insufficient vibration of concrete at the joint. Force requirements will affect the safety and quality of the project. [0003] In order to further improve the design quality of highway engineering, combined with the key technologies and applied research subjects of steel structure and concrete composite thin-walled high piers, some bridge piers on a ram...

AI Technical Summary

Problems solved by technology

The length of the four skeleton angle steels is designed to be welded on both sides, and the welding requirements are in accordance with the steel structure construction specifications; however, due to errors in the processing of steel column specifications, positioning during installation, and concrete pouring, the construction technology of the butt joint length of the skeleton cannot meet the requirements Construction and quality control requirements, the docking construction progress is slow, which greatly affects the construction period, and the quality is not guaranteed, there are quality hidden dangers, high labor costs, and high input costs
