Solderless node connector for steel-concrete composite structure

Abstract

The invention discloses a solderless node connector for a steel-concrete composite structure, which belongs to the field of connection of steel structures and reinforced concrete structures during the construction of building engineering. The prior connection mode of the steel structures and the reinforced concrete structures has the disadvantages of uneven global stress of beam bodies, piercing, large field welding workload and the like. The solderless node connector comprises a steel column, an annular plate and more than one corbel, the annular plate and the steel column are welded together, more than one corbel is welded with the annular plate respectively or is processed into a whole body, and a top plate and / or a bottom plate of each corbel is provided with a reinforcing steel bar connector for installing reinforcing steel bars; the reinforcing steel bar connector comprises a mounting plate and more than two stiffening plates which play a role in force transfer, and the mounting plate is provided with more than one through hole for the reinforcing steel bars to pass through. The solderless node connector for the steel-concrete composite structure can realize the aims of reasonable connection of a plurality of connection nodes, the guarantee of reasonable stress of structures thereof, convenient processing, convenient and quick field installation, quick construction, and the reduction of field welding workload.

Description

technical field [0001] The invention relates to the field of connection between a steel structure and a reinforced concrete structure in building engineering construction, in particular to a jointless connector for a steel-concrete combined structure. Background technique [0002] Steel structures are more and more widely used in high-rise buildings, and the connection nodes between steel structures and concrete structures are also widely used in various construction fields. How to connect many connecting nodes reasonably to ensure reasonable structural force, convenient processing, convenient on-site installation, fast construction, and reducing the workload of on-site welding has become a subject that urgently needs to be improved. [0003] Several common connection methods between steel structures and concrete structures currently used have the following disadvantages in whole or in part: 1. Ring beams and well-shaped beams are unevenly stressed as a whole, and the struct...

Problems solved by technology

[0003] Several common connection methods between steel structures and concrete structures currently used have the following disadvantages in whole or in part: 1. Ring beams and well-shaped beams are unevenly stressed on the whole, the structure is heavy, and the structural design is greatly affected by the architectural design. , poor architectural appearance; 2. Piercing: There are components (corbels, steel bars, etc.) in the steel pipe column, which have a certain impact on the quality of concrete construction; 3. Welding of steel bars and steel: the on-site welding workload is large, the weather is greatly affected, the welding quality is difficult to guarantee, and the construction process is complicated, which has a great impact on the construction period

In order to better solve the connection problem between the steel bar and the steel in the construction of the steel-concrete composite structure in the prior art, people urgently hope that a kind of steel-concrete composite structure non-welded node connector will come out
