Description
Technical field
The present invention relates to a kind of L-type shear wall horizontal connected node, belong to building structure technology field.
Background technology
Shear wall is the body of wall watered by steel concrete.What be made up of shear wall bears structure that is vertical and horizontal force, is called shear wall structure.The lateral deformation stiffness of shear wall is very large, and it is mainly used to opposing horizontal force and bears vertical effect; Body of wall is simultaneously also as safeguarding and house partition member.Shear wall structure can be built very high, is mainly used in the dwelling construction of 12-30 layer.Shear wall structure replaces the beam column in frame construction as the structure of the main supporting member of building by reinforced concrete wall panel.Because the horizontal shear that will resist of highrise building mainly earthquake causes, so shear wall is than other form of structure, more can the horizontal shear of control structure effectively, the ability that opposing destroys is stronger, anti-seismic performance is better, and safety is higher, lives also very comfortable.In shear wall and shear wall junction, need shear wall is connected with shear wall to be an entirety, make shear wall keep continuously, under the effect of the external force such as seismic forces, vertical counter-force and horizontal shear can being transmitted, ensure building safety.At present; between shear wall and shear wall, L shape node has a variety of; the invention being 200720149365.6 as the patent No. relates to a kind of L shaped node of bidirectional, comprises concrete cover, longitudinal reinforcement, horizontal reinforcement, at the dense mesh that shear wall surface is arranged.Body of wall adopts bidirectional single-row reinforcement mode, horizontal reinforcement is in Nodes 90 ° bending, inflection point is thickness of concrete cover apart from the distance of shear wall external surface, development length after bending is more than or equal to 15 times of bending reinforcing steel bar diameter, in horizontal reinforcement, knuckle place arranges 1 longitudinal reinforcement, inside the surface of wall away from interior knuckle place, arrange 1 longitudinal reinforcement along horizontal reinforcement; Longitudinal reinforcement beyond node center district is evenly arranged, and its spacing is more than or equal to the spacing of the longitudinal reinforcement in node center district.Can reduce amount of reinforcement under the prerequisite ensureing anti-seismic performance, reduce construction cost, but it bears and transmits vertically and external force limited in one's ability of horizontal direction.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of shear wall that makes and connects at corner place for entirety and bear the strong L-type shear wall horizontal connected node of external force ability.
For solving the problem, the invention provides a kind of L-type shear wall horizontal connected node, comprise the first precast shear wall and the second precast shear wall, it is characterized in that: described first precast shear wall node side is provided with the first notch, first notch place is the thin arm of straight section, described second precast shear wall is provided with the second notch in node side, second notch place is the thin arm of L-type, piece is left in described first precast shear wall and the second precast shear wall junction, be Cast-in-place concrete in described first notch and the second notch, the first sleeper stirrup and sleeper vertical reinforcement is provided with in described Cast-in-place concrete, the second sleeper stirrup and the second horizontal reinforcement is provided with in described second precast shear wall, described second horizontal reinforcement extends to the bending of LXing Bao arm edge, the first horizontal reinforcement is provided with in described first precast shear wall, described first horizontal reinforcement extends to the bending of straight section Bao Bei edge, described first sleeper stirrup is crossing in Cast-in-place concrete with the second sleeper stirrup.
Aforesaid L-type shear wall horizontal connected node, is characterized in that: described piece is 15mm.
Aforesaid L-type shear wall horizontal connected node, is characterized in that: described first horizontal reinforcement and the rear straight length of the second horizontal reinforcement bending are not less than 10d, and d is horizontal reinforcement diameter.
Aforesaid L-type shear wall horizontal connected node, is characterized in that: the thin arm of described straight section and the thin arm thickness of L-type are 30mm.
The beneficial effect that the present invention reaches:
Two precast shear walls are vertically connected by Cast-in-place concrete by L-type shear wall horizontal connected node of the present invention, sleeper vertical reinforcement, the first sleeper stirrup and the second sleeper stirrup is provided with in Cast-in-place concrete, two precast shear walls are connected securely, whole L-type shear wall is made to bear external force ability strong, and this node structure is simple, easy construction, cost is low.
