Abstract
The utility model discloses a concrete earthquake-proof wall configured with an inclined steel bar, comprising a wall body, wherein a steel bar net is distributed in the wall body and the steel bar net is formed by crossing two groups of parallel steel bars; each group of the steel bars is formed by a plurality of steel bars; the crossed included angle of the two groups of the steel bars is 30-90 degrees; and the included angle between one group of the steel bar and a horizontal direction of the wall body is 30-60 degrees. The concrete earthquake-proof wall disclosed by the utility model has the beneficial effects that a crossly-arranged anti-shearing stressing system is formed by the steel bar net which is obliquely arranged so that the tension performance of the steel bars is completely expressed and the whole anti-shearing performance of the concrete wall body is improved. The tension performance of crossed oblique steel bars is completely utilized and the anti-tensioning performance of the concrete wall along the oblique direction under the shearing force effect is improved, so that the anti-shearing bearing force of the concrete wall is improved. The oblique direct stressing steel bars are arranged so that the wall can still work under the shearing force effect even if the concrete does not work; and therefore, the ductility performance of the concrete wall body is improved and the brittle break of the earthquake-proof wall is avoided.
Description
Technical field
The utility model relates to a kind of concrete seismic structural wall, earthquake resistant wall that disposes oblique reinforcing bar.
Background technology
The concrete seismic structural wall, earthquake resistant wall is a form of structure important in the architectural structure system, and seismic structural wall, earthquake resistant wall structure, frame segment Zhi Kangzhen wall construction, frame shear-wall structure, framework-core barrel structure, tube in tube structure, the sheet-pile-form of structure such as seismic structural wall, earthquake resistant wall structure formed thus are the main Aseismic Structure System in cast-in-situ concrete house.
Receiving on the force mode, seismic structural wall, earthquake resistant wall presents curved on the whole and receives force mode; But every layer seismic structural wall, earthquake resistant wall is the force mode that receives of shearing shape.The arrangement of reinforcement of traditional seismic structural wall, earthquake resistant wall is horizontal distribution reinforcing bar and vertical distribution reinforcement quadrature arrangement, and is horizontal vertically flat.Shearing resistance according to shear wall receives force mode; Shearing diagonal crack mainly is to be positioned on the diagonal; Or be 45 °; The arrangement of reinforcement of body of wall and the angle of diagonal crack also are about 45 ° at this moment, and the stress of reinforcing bar does not overlap with concrete stress or is vertical, causes the tensile property of reinforcing bar not give full play of.The concrete of seismic structural wall, earthquake resistant wall is sheared because of integral body, and when causing concrete by drawing crack or conquassation, reinforcing bar is not surrendered, and this has just caused the waste of reinforcing bar material.Its basic reason is that reinforcing bar is asynchronous with concrete arrival stress peak, causes brittle fracture, has reduced the ductile performance and the ultimate bearing capacity of seismic structural wall, earthquake resistant wall.
The utility model content
The purpose of the utility model is exactly in order to address the above problem; A kind of concrete seismic structural wall, earthquake resistant wall that disposes oblique reinforcing bar is provided; Its steel mesh reinforcement through oblique layout has formed the shearing resistance stress system of arranged crosswise; Make the examining tensile behavior of reinforcing bar obtain giving full play to, improved the integral anti-shearing performance of concrete wall.
To achieve these goals, the utility model adopts following technical scheme:
A kind of concrete seismic structural wall, earthquake resistant wall that disposes oblique reinforcing bar; Comprise body of wall; Be distributed with steel mesh reinforcement in the body of wall, steel mesh reinforcement is made up of two groups of parallel reinforcing bars intersections, and every group of reinforcing bar is made up of many reinforcing bars; The cross angle of two groups of reinforcing bars is 30 °～90 °, and wherein the horizontal direction angle of one group of reinforcing bar and body of wall is 30 °～60 °.
Preferably, the cross angle of two groups of reinforcing bars is 90 °, i.e. two groups of reinforcing bar square crossings, and wherein the horizontal direction angle of one group of reinforcing bar and body of wall is 45 °, correspondingly, horizontal direction angle of another group reinforcing bar and body of wall also is 45 °.
The said body of wall left and right sides is provided with edge member, and the end anchorage of reinforcing bar is on the edge of in the member.Another kind of situation is: the body of wall left and right sides is provided with edge member, and body of wall is provided with side bar in both sides up and down, and the end anchorage of reinforcing bar is on the edge of in member and the side bar.
Carry out drawknot by the reinforcing bar drag hook between the reinforcing bar of said intersection.
The reinforcing bar of the oblique configuration of the utility model is all oblique layout when colligation.Should note protecting the reinforcing bar that diagonally distributes of concrete seismic structural wall, earthquake resistant wall during concreting, guarantee its oblique layout, give full play to the examining tensile behavior of reinforcing bar, better confined concrete.
The utility model is the arrangement of reinforcement in the concrete wall, changes oblique square crossing net sheet into by level and vertical cross wise reinforcement net sheet, forms the reinforced mesh that forms 45 ° or 135 ° with floor.Distribution reinforcement is oblique, and the reinforcing bar of another one direction is vertical with it, also is the reinforcing bar of oblique layout.There is edge member at the two ends of body of wall, improve whole anti-bending strength and the ductile performance that adds the reinforced concrete seismic structural wall, earthquake resistant wall.
The beneficial effect of the utility model is: formed the shearing resistance stress system of arranged crosswise through the steel mesh reinforcement of oblique layout, made the examining tensile behavior of reinforcing bar obtain giving full play to, improved the integral anti-shearing performance of concrete wall.Make full use of and intersect the examining tensile behavior of oblique reinforcing bar, improved concrete wall in the shearing action lower edge oblique tensile property, thereby improved the shear-carrying capacity of concrete wall.Through the layout of oblique direct steel bar stress, even concrete has withdrawed from work, this sheet wall still can be worked under shearing action, has improved the ductile performance of concrete wall thus, has avoided the brittle fracture of seismic structural wall, earthquake resistant wall.
