Curling steel structure structure and its construction method

Abstract

Provided are a curling steel structure and a construction method thereof. A node structure of the curling steel structure comprises a curling cup at the bottom, a curling bolt at the top and a curling handle connected onto the curling bolt, wherein the curling bolt comprises curling bolt curved-surface members radially distributed between a radial curved column and a curling top curved beam at intervals, flat-straight sections on the lower sides of the curling bolt curved-surface members are provided with clamping grooves matched with frame beams in size and shape, and the edges of the frame beams are connected with the clamping groove through all-around welding. The construction method of the node structure of the curling steel structure comprises the steps of prefabricating the members; forming the clamping grooves at the bottoms of the curling bolt curved-surface members; installing frame columns, the frame beams, the radial curved column and dimensional curved beams; hoisting the curling bolt curved-surface members; connecting the edges of the frame beams and the clamping grooves through all-around welding. The technical problem that an irregular steel structure in a curling shape cannot meet the strength requirement of member connecting nodes and cannot meet the bearing requirement by adopting a common steel structure connecting mode is solved.

Description

technical field [0001] The invention belongs to steel structure engineering, in particular to a curling 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 curling-shaped special-shaped steel structure includes the body at the bottom, the handle and bolt at the top, where the edge of the bolt and the body have a certain raised arc. Compared with the ordinary regular round pot shape, the steel structure of the curling pot shape has a larger section size, which has higher requirements on the strength of the connecting nodes of the components, and has certain restrictions on its load bearing. Therefore, it is necessary not only to meet the load-bearing requirements, but also to ensure that the overall shape does not change. The ordinary steel structure connection method cannot meet the design requirements. Contents of the...
