Body, at least laterally two vertical steel plates are embedded with inside the concrete layer, each vertical equal matrix arrangement of surface of steel plate has
Several studs, the stud pass perpendicularly through vertical surface of steel plate and are welded on vertical steel plate, the double end spiral shell
The both ends of bolt are welded with nut, all portions of the stud be provided with through ultra-high performance concrete pour made of to it is double
The body that all portions of hook bolt connect as one.
Further, the cross sectional shape of the coupled column is rectangle.
Further, based on the length of the vertical steel plate height 1/3-4/5.
Further, the Edge Distance coupled column of the vertical steel plate and the concrete surface top layer on basis are not less than 30mm.
Further, the vertical steel plate is shaped as rectangle, between vertical steel plate parallel to each other.
A kind of coupled column with horizontal anti-seismic performance and the construction method of base node structure, comprise the following steps：
（1）In all reserved solder joint in the two sides of vertical steel plate, several studs are vertically arranged in vertical surface of steel plate,
Welded at solder joint, several studs being fixed on vertical steel plate are in matrix arrangement；
（2）Stud the week side of boss on vertical steel plate two sides is inserted in pvc pipe, then with ultra-high performance concrete in double end spiral shell
Poured in die cavity between bolt and pvc pipe, and it is suitably conserved, it is right after ultra-high performance concrete reaches intensity
Pvc pipe carries out form removal, finally in the both ends WELD NUTS of stud；
（3）Will（1）Extremely（2）The vertical steel plate made in step is fixed at the connecting node on coupled column and basis, finally
The poured in place concrete layer at the connecting node on coupled column with basis, and it is suitably conserved.
Further, in step（2）In, the casting direction of ultra-high performance concrete is from surface of steel plate toward stud
End direction.
Compared with prior art, the invention has the advantages that：By coupled column with being adopted inside the connecting node on basis
Connected with vertical steel plate, on vertical steel plate two sides, appropriate location matrix formula is arranged with several studs, stud
Both ends are welded with nut, all portions of stud be provided with through ultra-high performance concrete pour made of to stud
The body that all portions connect as one, body use ultra-high performance concrete, are either all obtained significantly in tension and compression strength
Raising, be all 3-5 times of normal concrete intensity；This has the coupled column of horizontal anti-seismic performance and base node structure not only
Coupled column and vertical, the transverse steel of basic junction in tradition can be replaced, simplifies its cumbersome construction, and certain
Coupled column and the bearing capacity at foundation connection joint are improved in degree, especially horizontal resist forces are significantly improved；Secondly, erect
To the frictional force between steel plate and surrounding concrete and mechanical snap power, coupled column and base node region concrete are improved
Service behaviour, concrete is set to play larger effect, and coupled column and the concrete at base node in tradition, due to larger water
Flat load, easily occurs cleavage fracture；In addition, the body and stud of the ultra-high performance concrete being fixedly arranged on vertical reinforcement,
It can make node that there is higher intensity and preferable ductility, reduce the danger coefficient of its superstructure, once the ductility at node
Add, then its superstructure will not be damaged or collapsed easily, and more rescue times are provided to earthquake relief work；The present invention has
It is easy for construction, save material, significantly improve coupled column and base node on intensity and ductility, both can be used in building construction
At coupled column and base node, pier is can be used in bridge with cushion cap node, there is larger meaning.
