Abstract
The invention provides a kind of steel plate high-strength concrete composite coupling beams: this composite coupling beams comprises encased steel plate and builds the strong concrete between encased steel plate, steel plate high-strength concrete composite coupling beams of the present invention, by configuring steel plate substitute shear reinforcement outside concrete connecting-beam and concrete resisting shearing jointly, improves the shear-carrying capacity of coupling beam.By encased steel plate, effective effect of contraction is formed to strong concrete simultaneously, strong concrete fragility can be improved, improve supporting capacity and the deformability of coupling beam, thus be conducive to the cross section that Coupled Shear Wall structural system reduces coupling beam under the requirement meeting anti-seismic performance; This external application encased steel plate, as template, is constructed fast convenient.
Description
Technical field
The invention belongs to steel performance and combination construction technical field, relate to a kind of Shear-wall Connecting Beam Used, particularly a kind of steel plate high-strength concrete composite coupling beams.
Background technology
Coupling beam refers to the beam of connection wall limb and wall limb in shear wall structure system, and it is important energy dissipation component in highrise building.Under horizontal earthquake action, coupling beam can play the effect regulating shear wall anti-side rigidity and bearing capacity and ensure ductility of sheer wall by the surrender of self, thus reaches the object of consumption tectonic comparison.The intensity of coupling beam, rigidity and the anti-seismic performance of deformability on structure have to be affected significantly.
The destruction of coupling beam in wall of High-building under horizontal loads can be divided into brittle fracture and ductile fracture.Coupling beam just loses bearing capacity when there is brittle fracture, and when all there is shear failure along all coupling beams of wall overall height, each wall limb loses the effect of contraction of coupling beam to it, will become the independent wall of monolithic.This can make the lateral rigidity of structure greatly reduce, and distortion strengthens, and wall limb moment of flexure strengthens, and finally may cause collapsing of structure.Coupling beam there will be cross fracture under geological process, and form plastic hinge at beam-ends, the rigidity of structure reduces, distortion strengthens, thus absorb a large amount of seismic energies, still can continue to transmit bending and shearing by plastic hinge simultaneously, certain effect of contraction be played to wall limb, makes the Rigidity and strength that shear wall keeps enough.In this course, coupling beam serves a kind of effect of power consumption, and to minimizing wall limb internal force, delaying the surrender of wall limb has important effect.But under earthquake repeated action, the crack of coupling beam is understood development, is widened, until concrete compression destroys.
Therefore, the design of coupling beam needs to take certain corrective measure to ensure that coupling beam has certain rigidity and combines with the wall limb effectively connected, strengthen the globality of shear wall system, require that coupling beam shear failure does not occur simultaneously, namely require that the design of wall limb and coupling beam meets the principle of strong shear capacity and weak bending capacity, and the surrender of coupling beam early than the surrender of wall limb, will also require that coupling beam has good ductility and energy dissipation capacity.
Summary of the invention
The object of the present invention is to provide a kind of steel plate high-strength concrete composite coupling beams, this composite coupling beams can be good at the defect overcoming the appearance of existing coupling beam, the requirement of capability and deformation ability can be met, there is simple structure, easy construction, the reliable advantage of connection.
For achieving the above object, present invention employs following technical scheme:
This composite coupling beams comprises encased steel plate and builds the strong concrete between encased steel plate.
The surface of described encased steel plate opposite side is provided with some row's pegs.
Described encased steel plate is the coupling beam outsourcing template enclosed by the encased steel plate unit be oppositely arranged, and strong concrete is wrapped in coupling beam outsourcing template.
Described coupling beam outsourcing template is made up of four pieces of encased steel plate unit.
The steel ratio of described composite coupling beams is 0.04-0.2.
The invention has the beneficial effects as follows:
Steel plate high-strength concrete composite coupling beams of the present invention by configuring steel plate and substitute shear reinforcement and concrete resisting shearing jointly outside concrete connecting-beam, improve supporting capacity and the deformability of coupling beam, and avoid distress in concrete to expose, can the working range of prolongation structure normal operating condition, improve coupling beam functional performance and durability.This external application encased steel plate, as template, is constructed fast convenient; Steel plate high-strength concrete composite coupling beams of the present invention by configuring peg between steel plate, this novel composite coupling beams is enable to guarantee that steel plate is better coupled with concrete, collaborative work, prevents coupling beam generation brittle fracture, thus reaches the raising ductility of coupling beam and the object of energy consumption ability.
Steel plate high-strength concrete composite coupling beams of the present invention enables strong concrete be applied in the building in high-rise, super highrise building and high earthquake intensity area, particularly the high level in seismic fortification intensity more than 8 degree areas and super highrise building.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 1-Fig. 2, composite coupling beams of the present invention comprises encased steel plate and builds the strong concrete 2 between encased steel plate; The surface of described encased steel plate opposite side is provided with some row's pegs 3, by arranging the interaction that peg comes between Concrete Structure and steel plate between steel plate; Described encased steel plate is by the encased steel plate unit 1(steel sheet be oppositely arranged) the coupling beam outsourcing template that encloses, strong concrete 2 is wrapped in coupling beam outsourcing template; Described coupling beam outsourcing template is made up of four pieces of encased steel plate unit 1; The steel ratio of described composite coupling beams is 0.04-0.2.
Embodiment
By arranging novel steel-concrete composite coupling beams and the encased steel plate-Combined concrete coupling beam of steel plate in both sides, concreting coupling beam in encased steel plate, concrete is strengthened being connected by peg with steel plate.Described welding of peg is in the inner side of double-layer plate, vertical with steel plate, and is evenly arranged some rows along steel plate short transverse.Described encased steel plate is enclosed by four block plates of four sides and forms, and forms an outsourcing template, is wrapped in by concrete in outsourcing template.Concrete adopts strong concrete (more than C6).
This novel compositions coupling beam, by configuring steel plate substitute close longitudinal reinforcement of joining outside coupling beam and transverse reinforcement providing flexural strength and shear strength, is conducive to the ductility playing structure, avoids brittle fracture.Join the number of steel rate, determine the failure mode of component to a certain extent, therefore the steel rate of joining of cross-section of coupling beam can not be too low, can not be too high, and the present invention is according to " reinforced concrete composite structure design specifications " (JGJ138-2001) regulation: steel ratio α is within the scope of 0.04-0.2.
The steel plate of encased steel plate-Combined concrete coupling beam is formed by the Plate Welding of dimension as required, produce in specialized Gang Gou company in advance, then job site is transported to, assigned address weld with shear wall in place after, encased steel plate can be used as the template of construction stage concreting, thus saves the making of template, make construction simple and convenient while saving consumptive material in large quantities, can accelerating construction progress, improve efficiency of construction, create how better Social benefit and economic benefit.
