Abstract
The utility model relates to a two-way single-row reinforcing bars shear wall L-shaped node belongs to shear wall structure field and includes a concrete protection layer (2), a longitudinal reinforcing steel bar (3), a horizontal reinforcing steel bar (4) and a fine wire mesh (1) arranged on the surface of the shear wall. The walling adopts two-way single-row reinforcing bars mode. The horizontal reinforcing steel bar bends at the node with 90 degree. The distance from the bending point to the wall shear wall outer surface is the thickness of the concrete protection layer. The extending length after bending is larger than or equal to 15 times of the bend reinforcing steel bar diameter. One longitudinal reinforcing steel bar is arranged at the inner break angle of the horizontal reinforcing steel bar, one longitudinal reinforcing steel bar is arranged on the inner surface of the walling away from the inner break angle along the horizontal reinforcing steel bar. The longitudinal reinforcing steel bar outside the node center area is arranged evenly and the space is greater than or equal to the space between the longitudinal reinforcing steel bar inside the node center area. The adoption of the utility model can reduce the reinforcing steel bar consumption and decrease the construction cost on the premise of shock absorption performance guarantee and is applicable to multi-floor dwelling construction structure.
Description
Technical field
The utility model is the L shaped node of a kind of bidirectional single-row reinforcement shear wall, belongs to the shear wall structure field.
Background technology
The multilayer low-density residential buildings construction of China has more wide development space.After the loam brick multi-storey building is disabled, most masonry structure and the light section steel structures of adopting of multi-storey building.The overall performance and the anti-seismic performance of masonry structure are relatively poor, quality problems such as " heat, split, ooze, leak " occur easily; The light section steel structure cost is higher, and the fire line and the durability of structure are relatively poor.Common concrete shear wall structure is usually used in the high residential building construction, its reinforcement manner is two placing of reinforcement net sheets (the arrangement of reinforcement schematic diagram as shown in Figure 1), every placing of reinforcement net sheet is formed by longitudinal reinforcement 3 and horizontal reinforcement 4 colligations, usage level connecting lacing wire 6 sockets between the two placing of reinforcement net sheets, the L shaped node area of shear wall is provided with edge constraint stirrup 5, steel using amount is bigger, and cost is higher, is not suitable for applying in the multi-storey building structure.Bidirectional single-row reinforcement shear wall is the new structure of a kind of suitable multi-storey building of growing up on the basis of common shear wall structure, and it has given full play to the advantage of shear wall structure.Compare with the ordinary concrete shear wall structure, can under the prerequisite that satisfies the anti-seismic performance requirement, reduce the amount of reinforcement of shear wall, reduce the member section size, reduce cost, use in the multi-storey building that is adapted at having a large capacity and a wide range.
The structure design of bidirectional single-row reinforcement shear wall, seismic design and construction measure are different from traditional two-way double reinforcement shear wall, and existing " Code for design of concrete structures " fails to provide relevant method for designing and construction measure with " seismic design provision in building code ".
Summary of the invention
Technical problem to be solved in the utility model is to reduce the amount of reinforcement that the node cross section is L shaped two-way double reinforcement shear wall under the prerequisite that anti-seismic performance requires satisfying, and reduces cost.For this purpose, the utility model proposes L shaped design of node and structure thereof in the bidirectional single-row reinforcement shear wall.
The technical scheme that the L shaped node of the utility model bidirectional single-row reinforcement shear wall adopts is:
The cross section of shear wall node is L shaped; Body of wall adopts the bidirectional single-row reinforcement mode; Be the reduction construction cost, and avoid shear wall under the situation of single-row reinforcement, produce non-structural crack owing to concrete cover is excessive, use the dense mesh 1 of exempting to tear open to replace traditional formwork for placing on the shear wall surface; For guaranteeing the anti-seismic performance at concrete and reinforcing bar co-operation and node place, horizontal reinforcement 4 needs 90 ° of bendings at the node place, the inflection point is the thickness of concrete cover 2 apart from the distance of wall external surface, development length after the bending is more than or equal to 15d (d is the bending bar diameter), guarantee that horizontal reinforcement 4 has enough antidetonation anchorage lengths, interior knuckle place at horizontal reinforcement 4 arranges 1 longitudinal reinforcement 3, arrange 1 longitudinal reinforcement 3 in surface of wall inboard along horizontal reinforcement 4 away from interior knuckle place, make in the node center district (rectangular area of two bodies of wall overlap joint) to arrange 2 longitudinal reinforcements 3, amount to and arrange 4 longitudinal reinforcements 3 along every row of horizontal reinforcing bar 4; Longitudinal reinforcement 3 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 3.
The L shaped node of the utility model bidirectional single-row reinforcement shear wall, simple structure, easy construction.Adopt shear wall of the present utility model to compare, reduced amount of reinforcement and construction cost, reduced project total cost, be more suitable in the multi-storey building structure with the ordinary reinforced concrete shear wall.

The specific embodiment
2 couples of the utility model embodiment are described in further detail below in conjunction with accompanying drawing:
Arrange single longitudinal reinforcement 3 and single horizontal reinforcement 4 in the shear wall body of wall; Horizontal reinforcement 4 needs 90 ° of bendings at L shaped node place, the inflection point is the thickness 25mm of concrete cover 2 apart from the distance of wall external surface, development length after the bending is greater than 15d (d is the bending bar diameter), guarantee that horizontal reinforcement 4 has enough antidetonation anchorage lengths, interior knuckle place at horizontal reinforcement 4 arranges 1 longitudinal reinforcement 3, arrange 1 longitudinal reinforcement 3 in surface of wall inboard along horizontal reinforcement 4 away from interior knuckle place, make in the node center district (rectangular area of two bodies of wall overlap joint) to arrange 2 longitudinal reinforcements 3, amount to and arrange 4 longitudinal reinforcements 3 along every row of horizontal reinforcing bar 4; Longitudinal reinforcement 3 beyond the node center district arranges that evenly its spacing is greater than the spacing of the longitudinal reinforcement in the node center district 3; The shear wall surfaces externally and internally is arranged dense mesh 1.
