The structure of the shear wall is divided into three layers along the thickness direction, wherein an intermediate layer is a cast-in-situ regenerated concrete layer (2), and an upper surface layer (1) and a lower surface layer (1) are the precast common concrete outside plates; a horizontal reinforcement (3) and a vertical reinforcement (4) are arranged inside the precast common concrete outside plate layers on both sides; one end of a bonding reinforcement (5) is bound on a reinforcement mat, and the other end of the bonding reinforcement (5) is extended into the regenerated concrete layer; the length of the bonding reinforcement (5) is the thickness of the regenerated concrete layer; the horizontal reinforcement and the vertical reinforcement are extended out of the precast common concrete outside plates (1), and the length of the horizontal reinforcement and the vertical reinforcement is more than the reinforcement anchoring length; and the precast common concrete outside plates (1) are taken as templates of reinforced concrete members, cast in situ with regenerated concrete (2) in the middle, and combined into a whole. The shear wall and the processing method thereof solve the problem of damage of the ecological environment due to increasing shortage of natural aggregate and mining of a large quantity of sandstones.
Description
Technical field
The invention belongs to a kind of shear wall, particularly a kind of prefabricating common concrete outer plate recycled concrete core shear wall and processing method.
Background technology
Along with urbanization process is accelerated, present just with about 8,000,000,000 tons speed consumption natural aggregate in every year as the concrete of main constructional materials, meanwhile, increasing civil engineering construction project is scrapped dismounting, has produced a large amount of discarded concretes.Being the exploitation of a large amount of natural resources on the one hand, is the generation of a large amount of building wastes on the other hand.Concrete sustainable development and aggregate imbalance between supply and demand become increasingly conspicuous.
Regeneration concrete is being just energy-conservation with it, joint soil, sharp useless and improve characteristic such as environment, shows powerful vitality.Achievement in research to the regeneration concrete fundamental characteristics has shown that regeneration concrete can satisfy the performance requirement of ordinary concrete substantially, can be applied to the common engineering structure both at home and abroad.Yet regeneration concrete does not have high volume applications owing to durability, bearing capacity etc. are inferior to ordinary concrete in the actual engineering, be difficult to solve the contradiction that ecological environment goes from bad to worse.Shear wall structure is that the present highrise building of China is used maximum form of structure, also is the form of structure of regeneration concrete possibility high volume applications.Prefabricating common concrete outer plate recycled concrete core shear wall is given full play to the two advantage of ordinary concrete and regeneration concrete, can satisfy existing earthquake resistant code, can develop green concrete again.
Summary of the invention
Technical problem to be solved by this invention is to give full play to two kinds of concrete advantages, satisfies existing standard shockproof requirements, solves a large amount of discarded concrete difficult treatment and by the ecological environment that it the causes problem that goes from bad to worse.For this purpose, the present invention proposes a kind of prefabricating common concrete outer plate recycled concrete core shear wall.
The technical solution used in the present invention is: the intermediate layer is cast-in-place regeneration concrete layer 2, and upper epidermis 1 and following top layer 1 are prefabricating common concrete outer plate.The thickness of prefabricating common concrete outer plate is greater than 50mm, and horizontal steel bar 3 and vertical arrangement of reinforcement 4 are formulated in the prefabricating common concrete outer plate layer of both sides, and 5 one of tension ribs are tied up on steel mesh reinforcement, and one puts in the regeneration concrete layer, and length is the regeneration concrete layer thickness.Prefabricating common concrete outer plate 1, horizontal vertical reinforcement stretch out the outer length of plate 〉=40 times of bar diameters.
According to technical scheme of the present invention, adopt the preparation method of prefabricating common concrete outer plate recycled concrete core shear wall, its order is as follows:
1) colligation monolithic shear force wall reinforcing steel bar net, on colligation of tension rib and the steel mesh reinforcement, one is unsettled;
2) cast common concrete outer plate, steel mesh reinforcement is a protective layer thickness apart from the punching block distance;
3) tension rib stretch out is as the inside, the concrete plucking.
4) form removal after the maintenance.
5) concrete outer plate is concentrated be transported to the building site, during construction, prefabricating common concrete outer plate is as template, with side wooden form formwork, cast-in-place regeneration concrete.
6) maintenance reaches intensity, and the wooden form of dismantling, ordinary concrete just are connected as a single entity with regeneration concrete
The present invention compared with prior art has following remarkable advantages and beneficial effect:
Prefabricating common concrete outer plate recycled concrete core shear wall has been given full play to two kinds of concrete advantages.Aspect outward appearance, be equal to the ordinary concrete structure fully; Aspect durability, the bearing capacity aspect is equal to the ordinary concrete structure substantially.Because the constraint of ordinary concrete shell is arranged, and the resistance to compression bearing capacity and the ductility of regeneration concrete are not fully exerted.With the thick shear wall of 250mm is example; the thick ordinary concrete of 100mm is wherein arranged; the thick regeneration concrete of 150mm; regeneration concrete accounts for 3/5ths; a large amount of discarded concrete difficult treatment have been solved like this and by problems such as the ecological environment that it causes go from bad to worse; solved natural aggregate day by day weary the and a large amount of sandstones of plaque exploited the problems such as destruction that ecological environment is caused, protected existent environment of people, guaranteed the sustainable development of human society.Therefore, prefabricating common concrete outer plate recycled concrete core shear wall is a kind of green concrete member of sustainable development.

The specific embodiment
Be described in further detail below in conjunction with 4 pairs of embodiment of the invention of accompanying drawing 1～accompanying drawing:
Embodiment: prefabricating common concrete outer plate recycled concrete core shear wall, it is by prefabricating common concrete outer plate 1, cast-in-place regeneration concrete 2 superpositions, it when construction prefabricating common concrete outer plate 1 as the template of reinforced concrete member, middle cast-in-place regeneration concrete 2 is combined into one after the engineering completion.
1) make common concrete outer plate 1 with punching block, thickness is not less than 50mm, a plucking.
2) prepare level 3, vertical reinforcement 4 and tension rib 5 by current specifications, the vertical muscle of level stretches out the anchorage length of steel bar that the outer length of plate is not less than existing " Code for design of concrete structures " regulation.
3) one of tension rib is tied up on steel mesh reinforcement, and one is stretched out plucking one side in the concrete slab.Length is regeneration concrete in-situ layer thickness.
