Abstract

The invention is a variable section conversion node for profiled steel concrete framework-steel support structure, interconnecting in-pillar profiled steel, in-beam profiled steel, steel support, in-pillar reinforced concrete and in-beam reinforced concrete and pouring then into an organic whole, where the steel support is orthogonally connected with in-pillar an in-beam profiled steel flange plates by section conversion, the web of the in-beam profiled steel in the node connection position is converted into heightening variable section web and the top surface of the heightening variable section web is welded with widening variable section upper wing plate, the bottom surface of the heightening variable section web is welded with widening variable section lower wing plate; the shape of the steel support in the node connecting position is converted into structure of variable section node conversion region and two flange plates of the steel support in variable section conversion region are orthogonally connected with the in-pillar and in-beam profiled steel respectively. And the invention intensifies fore bearing performance of node regions of the profiled steel concrete framework-steel support structure and ability of cooperating of profiled steel and reinforced concrete.

Description

(1) Technical field

[0001] The invention relates to a node structure of a steel support and a steel beam column in a steel-concrete composite building. (2) Background technology

[0002] The National Gymnasium is one of the three main venues for the Beijing 2008 Olympic Games. During the Olympic Games, gymnastics competitions and handball finals will be held mainly, and wheelchair basketball competitions will be held during the Paralympic Games. Its buildings are composed of a competition hall and a warm-up hall. The competition hall can accommodate about 19,000 spectators, with a total construction area of โ€‹โ€‹80,890m 2 , one basement and four floors above ground. The longitudinal length of the roof plane projection is 195.5m, and the horizontal width is 114m.

[0003] Steel Reinforced Concrete Composite Structure (SRC structure for short) is a main form of steel and concrete composite structure. The characteristic of the steel concrete structure is that the steel is confi...
