Steel reinforced concrete composite structure beam column core area joint structure and construction method
The invention discloses a steel reinforced concrete composite structure beam column core area joint structure and a construction method. The joint structure comprises a steel reinforced concrete column and a concrete beam in the flange and web direction. The steel reinforced concrete column comprises a profile steel stand column and column longitudinal steel bars arranged on the periphery of the profile steel stand column, a plurality of octagonal stirrups and peripheral stirrups are arranged on each column longitudinal steel bar at intervals, and a plurality of steel bar drag hooks are arranged between a profile steel stand column web and the column longitudinal steel bars. The flange direction concrete beam comprises a plurality of rows of flange direction concrete beam longitudinal main reinforcements and flange direction concrete beam stirrups; the web direction concrete beam comprises a plurality of rows of web direction concrete beam longitudinal load-bearing steel bars and a plurality of web direction concrete beam stirrups. The joint structure is matched with the construction method thereof, construction is convenient, the construction efficiency of the joint structure is greatly improved, meanwhile, strength weakening and stress concentration caused by section steel column flange and web opening are avoided, and it is ensured that the strength of the steel reinforced concrete composite structure can meet the design requirement.
本发明公开了一种型钢混凝土组合结构梁柱核心区节点构造及施工方法，所述节点构造包括钢骨砼柱以及翼缘、腹板方向的混凝土梁；钢骨砼柱包括型钢立柱和设于型钢立柱外周的柱纵向钢筋，各柱纵向钢筋上间隔设有若干八边形箍筋和外围箍筋，型钢立柱腹板与柱纵向钢筋之间设有若干钢筋拉钩；翼缘方向混凝土梁包括若干排翼缘方向混凝土梁纵向主筋及翼缘方向混凝土梁箍筋；腹板方向混凝土梁包括若干排腹板方向混凝土梁纵向受力钢筋及若干腹板方向混凝土梁箍筋。所述节点构造配合其施工方法，不仅施工方便，而且大大提高该节点构造的施工效率，同时避免了型钢柱翼缘、腹板开孔造成的强度削弱及应力集中，确保了型钢混凝土组合结构的强度能满足设计要求。
