Description
Technical field
The utility model relates to a kind of L type shear wall horizontal connecting node, belongs 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 be connected to an 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; L shaped node has a variety of between shear wall and the shear wall; as the patent No. is that 200720149365.6 utility model relates to the L shaped node of a kind of bidirectional single-row reinforcement shear wall, comprises concrete cover, longitudinal reinforcement, horizontal reinforcement, at the dense mesh of shear wall surface arrangement.Body of wall adopts the bidirectional single-row reinforcement mode, horizontal reinforcement is 90 ° of bendings at the node place, the inflection point is a thickness of concrete cover apart from the distance of shear 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, arranges 1 longitudinal reinforcement in the surface of wall inboard away from interior knuckle place along horizontal reinforcement; Longitudinal reinforcement beyond the node center district arranges that evenly its spacing is more than or equal to the spacing of the longitudinal reinforcement in the node center district.Can reduce construction cost guaranteeing to reduce amount of reinforcement under the prerequisite of anti-seismic performance, but it bears and transmits vertically and the external force of horizontal direction limited in one's ability.
