Description

Coupled column and base node structure and its construction method with horizontal anti-seismic performance
Technical field
The invention provides a kind of coupled column with horizontal anti-seismic performance and base node structure and its construction method.
Background technology
At present, it is conventional(Combination)Post-foundation connection joint construction mainly both Vertical Reinforcements enter with horizontal arrangement of reinforcement Poured together after row colligation.Although the node of the connected mode is rigid, but ductility is poor, easy at geological process lower node It is damaged, the concrete in especially post-base node region is easily damaged, and causes the cracking of concrete cover so that it is anti- Shock stability deficiency.In addition, being to ensure the strength and stiffness at node, it can correspondingly increase the ratio of reinforcement at node, and now steel Clear distance between muscle and reinforcing bar can reduce, under powerful horizontal loads, once node region concrete cracking or damage, then It is easier to be destroyed at node.In addition, for single group zygostyle and basic junction construction, its post and the concrete on basis All consumed with amount of reinforcement it is more, in post vertical reinforcement will deeply basis in and after certain depth bend anchoring, to construction Bring certain being not easy and trouble.
The content of the invention
The purpose of the present invention is to be directed to above weak point, there is provided a kind of coupled column and base with horizontal anti-seismic performance Plinth node structure and its construction method.
Scheme is a kind of coupled column and base section with horizontal anti-seismic performance used by the present invention solves technical problem Point structure, including coupled column and basis, the coupled column are connected as one with the concrete layer through pouring at the connecting node on basis 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.
