A special-shaped cantilevered steel structure and its construction method

Abstract

The invention discloses a special-shaped cantilevered steel structure. The special-shaped cantilevered steel structure comprises a pot-shaped body in a steel structure, wherein the pot-shaped body consists of a pot cup, a pot bolt connected with the top part of the pot cup, and a pot handle connected with the pot handle, wherein the pot handle comprises at least eight main rods which are distributed symmetrically and a tubular truss consisting of web rods connected among the main rods; the tubular truss comprises a cantilevered section and a support section, wherein the cantilevered section is cantilevered above the pot handle and has a closed end; the support section is in a hopper shape with narrow upper part and wide lower part which is formed by extending the other opening end of the cantilevered section downward and is used for fixedly connecting one side of the pot bolt. The construction method comprises the following steps: mounting the pot bolt and splicing the pot handle; determining the position of a main pipe; mounting wed rods; hanging the support section; mounting the cantilevered section; splicing the support section and the cantilevered section. By the special-shaped cantilevered steel structure and the construction method thereof, the technical problems that the mounting requirement of a connecting node cannot be met by using an ordinary cantilevered structure and an ordinary connecting form because the cantilevering distance is long, the pot handle is large in size and heavy in weight, and the weight bearing requirement cannot be met are solved.

Description

technical field [0001] The invention belongs to steel structure engineering, in particular to a special-shaped cantilevered steel structure and a construction method thereof. Background technique [0002] With the rapid development of modern architectural design, architectural appearance is becoming more and more diversified. The special-shaped steel structure in the shape of a curling pot includes a cup at the bottom, a bolt on the top, and a handle connected to the bolt. Compared with the shape of a regular round pot, the cross-section of the steel structure in the shape of a curling pot is larger. [0003] The pot handle is a large-span cantilever structure connected to the pot bolt. The cantilever distance is relatively long. The pot handle is large in size and heavy in weight. There are few connection points with the pot bolt (base steel structure), and there are no other support points except the pot bolt. , the ordinary cantilever structure and the connection form of...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special-shaped cantilevered steel structure and its construction method. To solve the shape of the curling cantilevered steel structure, due to the long cantilever distance, large handle size and heavy weight, ordinary cantilevered structures are used. and the connection form cannot meet the installation requirements of the connection nodes of the two, and the technical problems that cannot meet the load-bearing requirements

In addition, it is necessary to solve the technical problems that the pot handle is far away from the crane, and there are great difficulties in the installation process. The amount of welding at the pot handle is relatively large, the space is quite narrow, and the welding work is dangerous and complicated.
