Steel column manhole structure and mounting method thereof

Abstract

The invention relates to a steel column manhole structure. Slope openings are formed in the left and right sides of a manhole plate; a round pin is fixedly connected to the right side of the manhole plate, the round pin is installed in a sleeve, and the sleeve is fixedly connected with the right side of a steel column manhole; and a casing is arranged on the left edge of the steel column manhole, a joint bar is arranged in the casing, and the right end of the joint bar is clamped on the surface of the manhole plate. The invention further provides a mounting method of the steel column manhole structure. An L-shaped steel bar is welded to the right side of the manhole plate, the sleeve is installed on the L-shaped steel bar, and then the sleeve is welded beside the steel column manhole; when the manhole is closed, the manhole plate is flatly turned to enter the steel column manhole, and easily rusted metal is inserted into a gap between the left side of the manhole plate and the steel column manhole; the steel casing is welded to the left edge of the steel column manhole, the joint bar is inserted into the casing, and the right end of the joint bar is pressed on the right side surface of the manhole plate; during supervision and acceptance, the joint bar is removed, the easily rusted metal is taken out, and the manhole plate is opened; and the manhole plates of all steel columns are welded after acceptance. The mounting method has the advantages of high mounting speed of the manhole plate and high construction safety.

Description

technical field [0001] The invention belongs to steel column construction in building engineering, and in particular relates to a steel column manhole structure and an installation method thereof. Background technique [0002] The installation of steel structure columns is a key structure in steel structure construction projects, which directly affects the construction progress and quality of the main structure of the project. The steel column is an important component that transmits the load on the floor to the foundation. During the welding process, the large cross-section steel column often needs to be welded with cross partitions inside on site. The cross partition plays an important role in ensuring the strength of the steel column. During the construction of the steel column or after the overall welding is completed, the supervisor needs to carry out a concealed acceptance of the welding site of the partition. The manhole is the construction opening reserved by the wo...

Problems solved by technology

During the construction process, it is not only cumbersome and inconvenient to operate, but also has certain safety hazards

It is also necessary to add hanging points on the steel column, which is not conducive to the protection of the finished steel components, it is not convenient for on-site installation and welding positioning, and it will increase the amount of labor, which is not conducive to the control of project costs.
