Abstract
The invention discloses a connecting joint for a buckling-restrained brace and a concrete frame beam; an anchoring part is formed by integrally welding one group of spaced H-shaped profile steels and upper and lower anchoring plates; a joint plate is integrally welded with the lower anchoring plate; two ends of the lower anchoring plate are lengthened to be longer than the lateral side of the joint plate; and bolt holes for fixed connection of a buckling-restrained brace are formed at two sides of the joint plate. The joint has the advantages: the H-shaped profile steels have good stability in a vertical plane and are high in rigidness and not easy in unstability; the profile steels have big welded areas with the anchoring plates and are not easy to produce pulling/pushing damage; the profile steels have big contact and load-transfer areas with the concrete and are capable of uniformly dispersing the load to the concrete beam; the lengthened parts at two ends of the lower anchoring plate are capable of effectively avoiding direct extrusion between the joint plate and the concrete, so that the stress concentration is relieved and the service life of the joint is prolonged; a clearance is formed between two profile steels, the integrality of the concrete beam is not influenced, the arrangement of hoops and longitudinal ribs in the concrete beam is not influenced and the construction is convenient; the steel ratio in the joint area of the concrete beam is increased and the strength and rigidness of the joint is improved by the plastic deformation of the beam restrained by the upper and lower anchoring plates; the whole component can be manufactured in a factory and the construction time is saved.
Description
Technical field
The present invention relates to building structural member, particularly a kind of buckling restrained brace and concrete frame beam connecting node.
Background technology
Band buckling restrained brace concrete frame structure because having anti-seismic performance, easy construction and save material etc., just apply at building field by superiority.Wherein the connected node of buckling restrained brace and concrete frame is a very important ring in total, requires to have enough intensity, suitable rigidity, enough turning powers, can reasonably Transfer of Shear and moment of flexure; To easily make and easy construction simultaneously.Good node will meet the design principles of " strong node, weak component ".
Existing buckling restrained brace and concrete frame beam connecting node have following several:
One is peg formula anchor connection node (node as disclosed in CN102011434A patent application).It is employing one piece of integral plate as node component, the upper lateral of steel plate is interted multiple peg, is anchored in concrete beam, as anchoring piece, the bottom of steel plate is exposed at outside concrete beam, as the gusset plate be fixedly connected with buckling restrained brace.The shortcoming of this node is: concrete beam cuts in half by monoblock steel plate, and the globality of concrete beam is weakened, and intensity reduces; Steel plate as occurred tilting, can produce when pressurized eccentric, directly being rived by concrete beam in formwork casting process; During colligation concrete beam stirrup, steel plate becomes obstacle, and construction is inconvenient.
Another kind is by the shape steel plate of steel plate instead with vertical convex tendon with peg in above-mentioned peg formula anchor connection node.This node still uses one piece of integral plate as node component, and its shortcoming is identical with above-mentioned peg formula anchor connection node.
The third is angle steel formula anchor connection node.It is anchored in concrete beam using one group of vertical angle steel integrally welded with upper and lower anchor slab as anchoring piece, gusset plate and lower anchor slab integrally welded.The shortcoming of this node is: angle steel symmetry and less stable; Angle steel and anchor slab bonding area less, easily produce drawing in loading process and destroy; Angle steel is with concrete to contact power transmission area less, and node strength is poor.
4th kind is dowel formula anchor connection node.It changes the angle steel in above-mentioned angle steel formula anchor connection node into vertical dowel.The shortcoming of this node is: dowel is poor at perpendicular internal stability; Dowel and anchor slab bonding area little, easily produce drawing in loading process and destroy; Dowel is with concrete to contact power transmission area less, and node strength is poor.
Summary of the invention
The shortcoming that the object of the invention is for above-mentioned prior art is improved, and provides a kind of and can better transmit bending and shearing, meets requirement for bearing capacity, the buckling restrained brace of convenient construction and concrete frame beam connecting node.
For achieving the above object, buckling restrained brace provided by the invention and concrete frame beam connecting node, be made up of the anchoring piece be anchored in concrete frame beam and the gusset plate being placed in concrete frame beam bottom; Described anchoring piece is made up of one group of spaced H profile steel, the top and bottom of H profile steel respectively with upper anchor slab and lower anchor slab integrally welded, the inward flange of upper anchor slab and lower anchor slab is in the outside of concrete frame beam; Described gusset plate and lower anchor slab integrally welded, the two ends of lower anchor slab 4 lengthen 200mm than the side of gusset plate; There is vertical stiffening rib the center of gusset plate, gusset plate has the bolt hole be fixedly connected with for buckling restrained brace.
As required, vertical stiffening rib can be established in the center of gusset plate.
Compared with prior art, advantage of the present invention is:
1, H profile steel perpendicular internal stability and rigidity high, not easily unstability.
2, H profile steel and anchor slab bonding area are greatly, be not easy to produce drawing and destroy in loading process.
3, H profile steel contacts power transmission area comparatively greatly with concrete, power can be evenly spread in concrete beam.
4, lower anchor slab two ends elongated portion can effectively avoid gusset plate and concrete directly to extrude, and slows down stress and concentrates, and extends the application life of node.
5, H profile steel has space each other, makes the globality of concrete beam unaffected; H profile steel spaced apart does not affect stirrup in former concrete beam and vertical muscle is arranged, convenient construction.
6, concrete girder connection region steel ratio increases, and upper and lower anchor slab to a certain extent can the plastic strain of restained beam, the strength and stiffness of node is all got a promotion, meets the design principles of " strong node, weak rod member ".
7, whole component can make in factory, in-site installation, saves the engineering time, is conducive to improving engineering efficiency.
