Abstract
The invention discloses a structure joint of a novel reinforced concrete column-steel beam (RCS) combined framework, which comprises a steel beam, a reinforced concrete column and high-strength connecting bolts, wherein the reinforced concrete column comprises a square-shaped steel plate barrel, longitudinal steel bars and a plurality of stiffened steel plates which are arranged in the square-shaped steel plate barrel and divide the square-shaped steel plate barrel into a plurality of cells in a cross sectional direction; the stiffened steel plates and the square-shaped steel plate barrel are welded into a whole; the longitudinal steel bars passes through the cells respectively; concrete is cast in the cells respectively; and the steel beam is connected to the outer barrel wall of the square-shaped steel plate barrel by connecting end plates and the high-strength connecting bolts. Compared with the prior art, the invention provides extremely high shear capacity for the square-shaped steel plate barrel and the stiffened steel plates in the square-shaped steel plate barrel in the joint area, thereby truly meeting the requirements for high-strength joints in the earthquake-resisting design. The joint dispenses with penetrating steel beams and penetrating connecting bolts and stirrups arranged in the core area of the joint. The joint has the advantages of simple structure and high construction operability, directly solves the difficult engineering problems of reinforcement binding and concrete casting in the core area of the RCS joint and has high practicability in engineering.
Description
Technical field
The present invention relates to a kind of concrete column-steel beam composite frame structure form of architecture joints, can be applicable to adopt the industry and the civilian construction of concrete column-steel beam combined structure system.
Background technology
Concrete column-steel beam (Reinforced concrete column-steel beam, RCS) combining structure is steel and concrete a kind of combining structure form, this structure has been given full play to steel and two kinds of materials of concrete advantage separately, its combination property is better than conventional steel tendon concrete frame structure and steel framed structure, is called as the form of structure of " low-cost high-efficiency ".Its main advantage is mainly reflected in: the span of (1) steel-concrete composite floor system system is big, from heavy and light, has bigger technical advantage in large span industrial premises and public building; (2) save superstructure concrete blinding and support, accelerating construction progress; (3) easy formation strong column and weak beam type failure mechanism under the violent earthquake effect, and damaged beam can conveniently be replaced and reuse, and is a kind of structural system of sustainable development.
In the RCS frame construction girder steel and reinforced concrete post can be respectively by corresponding norm of steel structure and the design of steel concrete standard, and the design of RCS node does not have standard and can comply with.Chinese scholars has been carried out many research work at the RCS node, develops through node of some girder steels and the through joint structure of concrete column.Wherein, the through joint cores construction measure of girder steel is more, the disturbing concrete difficulty, and the vertical muscle of post passes through the core space girder steel edge of a wing and the tie muscle passes through constructing operation complexity such as core space steel beam web plate; The screw rod traversed node core space of the through node of the bolted post of end plate, cause following problem easily: (1) a large amount of transverse and longitudinals are reserved screw hole and have been weakened node area anti-shear concrete ability, and joint behavior be cannot say for sure to demonstrate,prove; (2) screw rod of perforation column section is longer, and node rigidity is difficult to satisfy the rigid joint requirement; (3) partial pressing's destruction appears in concrete column and girder steel end plate contact surface easily.The existence of these problems has seriously restricted the application of RCS combining structure in engineering practice.
Summary of the invention
The purpose of this invention is to provide all more superior structure joint of novel reinforced concrete column-steel beam combined framework of a kind of shear behavior, rigidity and bearing capacity.
Technical solution of the present invention is as follows: structure joint of novel reinforced concrete column-steel beam combined framework comprises girder steel, concrete column, connection end plate and high-strength connecting bolt; Above-mentioned concrete column comprises square plate bucket, longitudinal reinforcement and the plural piece steel plate of putting more energy into, the above-mentioned steel plate of respectively putting more energy into is arranged at the interior cross-directional with above-mentioned square plate bucket of above-mentioned square plate bucket and is separated into a plurality of lattices, and above-mentioned steel plate and the above-mentioned square plate bucket of respectively putting more energy into is welded into an integral body, above-mentioned longitudinal reinforcement is passed by above-mentioned each lattice respectively, and is cast with concrete respectively in above-mentioned each lattice; Above-mentioned girder steel is connected on the outer barrel wall of above-mentioned square plate bucket by above-mentioned connection end plate and high-strength connecting bolt.
Offer through hole respectively on the above-mentioned steel plate of respectively putting more energy into, with enhancing put more energy into steel plate and concrete bonding of intranodal and shearing transmission.
Be welded with peg respectively on the above-mentioned steel plate of respectively putting more energy into, with enhancing put more energy into steel plate and concrete bonding of intranodal and shearing transmission.
After adopting such scheme, the present invention has following advantage: the steel plate of putting more energy in square plate bucket of (1) node area and the bucket provides great shear-carrying capacity, and the core space concrete is formed operative constraint, can really realize the strong node requirement in the seismic design.(2) joint cores need not to dispose stirrup, also need not girder steel and passes through, and can directly solve traditional RCS node center pillar stirrup and install and a casting and compacting of concrete difficult problem.(3) the square plate bucket with its intersect around girder steel end plate can be connected by high-strength bolt, also can strengthen by welding, can effectively guarantee the quality that connects to make that the rigidity of node and bearing capacity are all more superior.(4) cutting of joint cores steel plate workpiece and welding job are all finished in factory, reduce the field Welding workload, and quality is easy to control.(5) girder steel and concrete column all can adopt industrialized standard production in factory, realize the whole site assembly of RCS structure, and construction speed increases substantially.(6) damaged girder steel can conveniently be replaced and reuse under the violent earthquake effect, is a kind of structural system of sustainable development.
