Description
Technical field
The present invention relates to the syndeton between complete prefabricated assemble mechanism shear wall of a kind of steel concrete and the beam, 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 or beam junction, need make shear wall and plate or beam 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 beam 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; Transmit horizontal shear as the hollowcore slab of horizontal baffle, be applicable to multilayer and high residential building, but this node structure complexity, construction relative complex.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shear wall and beam of making becomes integral body and steel reinforced concrete full prefabricated assembly structural shear wall simple in structure and the connected node between the beam.
For solving the problems of the technologies described above, the invention provides the connected node between a kind of steel reinforced concrete full prefabricated assembly structural shear wall and the beam, comprise shear wall and precast beam groove, it is characterized in that: the width of described precast beam groove is identical with the thickness of shear wall, described precast beam groove is " recessed " font, described shear wall has a Baltimore groove at the node place, described precast beam groove stretches into Baltimore groove one segment distance of shear wall, in the Baltimore groove of shear wall and in the groove of precast beam groove is superimposed sheet cast-in-situ concrete, be provided with the additional muscle in beam bottom in the groove bottom of precast beam groove, the additional muscle in beam bottom stretches in the shear wall simultaneously, be provided with the additional muscle in beam top on the groove top of precast beam groove, the additional muscle in beam top stretches in the shear wall simultaneously, the additional muscle in additional muscle in beam bottom and beam top in shear wall and the length in the groove of precast beam groove satisfy the anchoring requirement, the reinforcing bar in the superimposed sheet cast-in-situ concrete of described precast beam groove top and the reinforcing bar of precast beam groove are an integral body.
The beneficial effect that the present invention reached:
Connected node between steel reinforced concrete full prefabricated assembly structural shear wall of the present invention and the beam, by the precast beam groove being set and being provided with additional muscle in the junction, cast on-site superimposed sheet cast-in-situ concrete again, institute is so that shear wall and beam connect into as a whole, can bear and transmit the external force that vertically reaches horizontal direction, guarantee the safety of building, and simple in structure, work progress is simple.
