Abstract
The utility model relates to a recycled concrete shear wall with an X-shaped reinforcing bar in the conversion layer, and belongs to a shear wall structure. The lower part of the shear wall is made of ordinary concrete, while the upper part of the shear wall is made of recycled concrete; the conversion layer at the middle part of the shear wall is three times the thickness of the shear wall, and an X-shaped bar raking prop is arranged in the conversion layer; and the bar raking prop is connected with a mesh reinforcement of the shear wall to form a concealed support inside the concrete shear wall. The utility model brings the advantages of the two types of concrete into full play, adopts a recycled concrete structure, and achieves the purposes of optimized structural design and ensured structural performance. The lower part of the shear wall, which tends to be acted upon by a larger shearing force, is made of the ordinary concrete with stable performance, while the upper part of the shear wall, which tends to be acted upon by a smaller shearing force, is made of the recycled concrete which is slightly inferior to the ordinary concrete in performance. In the conversion layer which is exposed to rigidity mutation, the arrangement of the X-shaped reinforcing bar not only can avoid shear slip between different concrete layers, but also can prevent the shear bearing capacity of the shear wall from undergoing sudden changes.
Description
Technical field
The utility model relates to a kind of band cross reinforcement conversion layer regeneration concrete shear force wall, belongs to a kind of shear wall structure system.
Background technology
At present, the quantity of China's building waste has accounted for 30%～40% of municipal refuse total amount, and wherein most important component is a discarded concrete; Meanwhile a large amount of natural sandstone aggregates are constantly exploited, and it is exhausted that the natural aggregate resource also will be tending towards.The regeneration concrete technology be one with after waste concrete block fragmentation, cleaning, the classification, make Aggregate of recycled concrete according to certain ratio mixing, partly or entirely replace natural aggregate to be mixed with concrete technology in the aggregate of making then, this The Application of Technology meets the requirement of human social.
In building structure, shear wall is the core antidetonation parts of building structure, is bearing the geological process of overall structure 80%, therefore, the regeneration concrete technology is applied to shear wall structure has broad prospects.Studies show that regeneration concrete intensity is low with respect to ordinary concrete, the bearing capacity catagen speed is also faster than ordinary concrete, and under geological process, the story shear on shear wall structure top is less than the story shear of bottom simultaneously.Thereby shear wall structure adopts bottom ordinary concrete, top regeneration concrete, can satisfy the seismic design requirement of the shear wall structure dwelling house that has a large capacity and a wide range, and has tangible environmental benefit simultaneously.Yet, shear wall adopt up and down that the different performance concrete forms the conversion layer place, the shear stiffness sudden change appears easily, form weak part, thereby influence the anti-seismic performance of total, so the problem of key is how conversion layer to be handled.Cross reinforcement is set at the conversion layer place not only can prevents shearing resistance slippage between the different layer of concrete, also can change the process that individual transition be arranged simultaneously the shear-carrying capacity of shear wall.
The utility model content
Technical problem to be solved in the utility model is in order to satisfy the requirement of existing standard seismic design, solves a large amount of discarded concrete difficult treatment and problem that the ecological environment that causes thus goes from bad to worse.In order to reach this purpose, the utility model proposes a kind of band cross reinforcement conversion layer regeneration concrete shear force wall.
The technical solution adopted in the utility model is: ordinary concrete is adopted in the shear wall bottom, and regeneration concrete is adopted on shear wall top, and the shear wall middle part is provided with conversion layer, and the conversion layer height is got 3 times shear wall thickness of wall body; The steel mesh reinforcement that configuration two rows are made up of transversely distributed steelbar and vertical distribution reinforcement respectively in the shear wall sockets with socketing reinforcing bar between the two placing of reinforcement nets; At shear wall conversion layer place, two placing of reinforcement net inboards are provided with the reinforcing bar bearing diagonal, and the reinforcing bar bearing diagonal is connected with the shear force wall reinforcing steel bar net, support inner the formation secretly of concrete shear force wall.
Described band cross reinforcement conversion layer regeneration concrete shear force wall, it is characterized in that: the reinforcing bar bearing diagonal that is provided with at shear wall conversion layer place is X-shaped, length in the shear wall of top is stretched into more than or equal to 2 times shear wall thickness of wall body in reinforcing bar bearing diagonal upper end, and with shear wall in the steel mesh reinforcement bind; Length in the shear wall of bottom is stretched into more than or equal to 2 times shear wall thickness of wall body in reinforcing bar bearing diagonal lower end, and with shear wall in the steel mesh reinforcement bind.
Band cross reinforcement conversion layer regeneration concrete shear force wall is given full play to two kinds of concrete advantages, has utilized the regeneration concrete structure, has optimized structure design, has guaranteed structural performance.Be subjected to the bigger shear wall bottom of shearing, adopting the ordinary concrete of stable performance, and be subjected to the less shear wall top of shearing, adopting the poor slightly regeneration concrete of performance.At the conversion layer place of rigidity sudden change, cross reinforcement is set can prevents shearing resistance slippage between the different layer of concrete, the shear-carrying capacity to shear wall changes the process that individual transition is arranged simultaneously.
