Abstract
The utility model discloses a connecting node structure for an existing concrete column and a new steel column. The connecting node structure comprises the new steel column, and is characterized in that studs are arranged on the periphery of the new steel column; the bottom end of the new steel column is connected with a shear key; an outer frame is arranged outside the new steel column; a piece of angle steel is arranged at each of the four corners of the outer frame; batten plates and angle steel strengthening plates are transversely connected between the angle steel arranged at the four corners; and pore plates are connected outside the batten plates. The utility model has the advantages that: the connecting node structure is easy to construct and operate, cannot damage but strengthen the existing node, and can transfer internal force effectively and achieve the purpose of strong node and weak component.
Description
Technical field
The utility model belongs to a kind of construction work link structure, particularly a kind of existing concrete column and newly-increased steel column connected node structure.
Background technology
[0002] increase in layer engineering at the reinforced concrete structure existing building, in order to reduce the reinforcing amount of basis and existing building structure, newly-increased part of building generally adopts the lighter steel work of deadweight.The connected node of newly-increased steel column and lower rebar concrete column requires to accomplish rigid joint; The internal force (axle power, moment of flexure, shearing) that is the top steel column should be passed to the lower rebar concrete column reliably; And accomplish the weak member of strong node; Usually way has two kinds: way one is vertical muscle 200mm-300mm in the reserved steel bar concrete column, with joint bar overlap welding in the upper post, steel column is installed again; The concrete column of cast-in-place one section about 1000mm height guarantees that steel column internal force is passed to lower prop through cast-in-place reinforced concrete post.Way two is that bar planting length will satisfy the requirement of lap length in reinforced concrete post crown drill hole bar planting, generally needs about 1000mm in the implant post, way behind the steel column is installed again with way one.Because the reinforcement ratio comparatively dense of existing bean column node inner beam, post, these two kinds of way difficulty of construction are big, and construction precision requires high, and construction wrong can cause very big destruction to bean column node, and structure is stayed potential safety hazard.
Summary of the invention
The purpose of the utility model provides a kind of existing concrete column and newly-increased steel column connected node structure, and constructing operation is simple, and to existing node not damaged and reinforcement to some extent, transmission internal force is accomplished the weak member of strong node effectively.
The purpose of the utility model is achieved in that it comprises newly-increased steel column, is characterized in that: the periphery at newly-increased steel column is provided with peg, connects shear key in the bottom of newly-increased steel column; Outside at newly-increased steel column is provided with angle steel for four jiaos, and weldable steel batten plate and angle steel were strengthened batten plate between angle steel was horizontal.
[0006]The utility model has the advantages that: constructing operation is simple, and to existing node not damaged and reinforcement to some extent, transmission internal force is accomplished the weak member of strong node effectively.

Fig. 3 is B-B sectional view of Fig. 1.
Fig. 4 is C-C sectional view of Fig. 1.
The specific embodiment
See Fig. 1-4, the concrete structure as follows: in the periphery weld stud 8 of newly-increased steel column 1, at the bottom welding shearing key 5 of newly-increased steel column 1; In the outside of newly-increased steel column 1 four jiaos be provided with 3, four jiaos of angle steel that are provided with of angle steel 3 laterally between weldable steel batten plate 2 strengthen batten plate 4 with angle steel, at the outer setting expanded metal lath 9 of batten plate.
During practical applications, the angle steel at four jiaos of the utility model place are set in the top of existing concrete column 7, angle steel is fixed on the former Vierendeel girder 6 through strengthening batten plate 4.Newly-increased steel column 1 is plugged in the steel framework of angle steel and batten plate formation, is poured into concrete, newly-increased steel column, steel framework form integral body.Four angle steel 3 transmit whole moments of flexure and thrust axis power, and bottom shear key 5 Transfer of Shear of newly-increased steel column, pressure axis power lean on the concrete resistance to compression to transmit, and accomplish the weak member of strong node.
