Description
Technical field
The present invention relates to a kind of T type shear wall vertical connection nodes, 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 shear wall junction, need make shear wall and shear wall become integral body, under the effect of external force such as seismic forces, can transmit vertical counter-force and horizontal shear, guarantee building safety.At present, shear wall T shape connected node has a variety of, and the application of the patent No. 200720149364.1 discloses a kind of bidirectional single-row reinforcement shear wall T-section point, comprises concrete cover, longitudinal reinforcement, horizontal reinforcement, dense mesh.Horizontal reinforcement need interlock 90 ° at the node place and bend that (promptly a row of horizontal distribution bar is to 90 ° of bendings of node one side; its next row of horizontal distribution bar is to 90 ° of bendings in the other direction); the inflection point is a thickness of concrete cover apart from the distance of wall external surface; development length after the bending is more than or equal to 15 times of the bending bar diameter; interior knuckle place at horizontal reinforcement arranges 1 longitudinal reinforcement; at 1 longitudinal reinforcement of surface of wall disposed inboard away from interior knuckle place; arrange 1 longitudinal reinforcement in the horizontal reinforcement intersection, the longitudinal reinforcement spacing beyond the node center district is more than or equal to the spacing of the longitudinal reinforcement in the node center district.This utility model can reduce amount of reinforcement under the prerequisite that guarantees anti-seismic performance, reduce construction cost, but external force resistance can be limited.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shear wall that makes and is connected to integral body and the strong T type shear wall vertical connection nodes of external force resistance ability at the place, corner.
For solving the problems of the technologies described above, the invention provides a kind of T type shear wall vertical connection nodes, comprise the first prefabricated shear wall and the second prefabricated shear wall, and the side that the second prefabricated shear wall and the first prefabricated shear wall are mutually close and the concrete of the first prefabricated shear wall segment distance of being separated by, it is characterized in that: the second prefabricated shear wall is provided with a groove at the node place, Cast-in-place concrete is positioned at the interval of groove and the second prefabricated shear wall and first shear wall, transverse reinforcement with the continuous side of the first prefabricated shear wall in the second prefabricated shear wall is not connected at the node place, be provided with the extension, two extensions are overlapped, being positioned at the inside bending segment in node place links to each other also vertical mutually with the extension, described extension and bending segment place in the Cast-in-place concrete, horizontal reinforcement in the described first prefabricated shear wall extends to the inside of Cast-in-place concrete, and bending inwards respectively in Cast-in-place concrete becomes second bending segment.
The beneficial effect that the present invention reached:
T type shear wall vertical connection nodes of the present invention, at the node place with two vertical shear reinforcing bar interlaced arrangement within the walls, and connect into the first prefabricated shear wall and the second prefabricated shear wall as a whole by Cast-in-place concrete, can bear and transmit the external force that vertically reaches horizontal direction, guarantee the safety of building.
