The invention makes the shearing wall and the precasting superimposed sheets into a whole, can bear and transfer external force vertical to the horizontal direction, and ensure the safety of buildings; and meanwhile, the node has simple structure and convenient construction.
Description
Technical field
The present invention relates to a kind of interior shear wall and plate and shear wall interlayer connected node, belong to the building structure technology field.
Background technology
Shear wall is the body of wall that is watered by steel concrete.The structure of bearing vertical and horizontal force by shear wall is formed is called shear wall structure.The lateral deformation stiffness of shear wall is very big, and it is mainly used to resist horizontal force and bears vertical effect; Body of wall is simultaneously also as safeguarding and the house partition member.Shear wall structure can be built very highly, is mainly used in the dwelling construction of 12-30 layer.Shear wall structure is by the structure of the beam column in the reinforced concrete wall panel replacement frame construction as the main supporting member of building.Cause because the horizontal shear that highrise building will be resisted mainly is earthquake, thus shear wall than other form of structure, the horizontal shear of control structure more effectively, the ability that opposing destroys is stronger, anti-seismic performance is better, and safety is higher, and it is also very comfortable to live.In shear wall and plate junction, need make shear wall and plate become integral body, make shear wall keep under the effect of external force such as seismic forces, can transmitting vertical counter-force and horizontal shear continuously, guarantee building safety.At present, the connected node of shear wall and plate has a variety of, the patent No. is the connected node that the utility model of CN97248704.2 discloses a kind of prestressed cored slab and concrete shear force wall and beam, form by concrete shear force wall, pre-tensioned prestressing hollowcore slab, anchor rib, it is characterized in that: the hole location at the hollowcore slab end is offered keyway, place reinforcing bar in the groove, reinforcing bar stretches into reinforcing bar anchoring in every story shear body of wall and the body of wall, satisfy the lap length of code requirement, concrete and shear wall concrete in the keyway are built simultaneously, make board wall or girder connection become integral body.This node connects, and can make shear wall keep under the effect of seismic forces, transmitting vertical counter-force and avoiding the hollowcore slab slump continuously; Hollowcore slab as horizontal baffle transmits horizontal shear, is applicable to multilayer and high residential building.But this complex structure, the work progress complexity.
Summary of the invention
Technical problem to be solved by this invention provides a kind of make interior shear wall and plate simple in structure, easy construction becomes whole interior shear wall and plate and shear wall interlayer connected node.
For solving the problems of the technologies described above, the invention provides a kind of interior shear wall and plate and shear wall interlayer connected node, shear wall and prefabricated superimposed sheet in comprising, it is characterized in that: two prefabricated superimposed sheets are positioned at the shear wall both sides, be provided with two rows at interior shear wall interior nodes place and reserve joint bar, reinforcing bar Joint in described reservation joint bar and the prefabricated superimposed sheet, the shear wall both sides that are positioned at prefabricated superimposed sheet top are provided with the Grouting Pipe that two rows are used for slip casting, described reservation joint bar is positioned at Grouting Pipe, on described prefabricated superimposed sheet top is the superimposed sheet in-situ layer, reinforcing bar in the superimposed sheet in-situ layer and the reinforcing bar in the prefabricated superimposed sheet are an integral body, described prefabricated superimposed sheet is opened at the bottom at node place booster breaking of muscle and tendon, extend forward at the node place respectively at two ends, and bend near the lateral of reserving joint bar, overlaps mutually with the reservation joint bar simultaneously.
Described Grouting Pipe is DN50.
The reservation joint bar of described shear wall one side is to the above 600mm of node, and opposite side is reserved joint bar to the 1000mm more than the node.
The beneficial effect that the present invention reached:
Shear wall and plate and shear wall interlayer connected node in of the present invention, be provided with the reservation joint bar in the junction, and Grouting Pipe cast-in-site superimposed sheet in-situ layer by making, institute is so that shear wall and prefabricated superimposed sheet connect into as a whole, can bear and transmit the external force that vertically reaches horizontal direction, guarantee the safety of building, simple, the easy construction of this node structure simultaneously.
