The utility model relates to a shear wall with an anti-seismic effect. Vertical joints are set in the concrete wall composed of concrete and wall reinforcement, and rubber belts are filled between the vertical joints, and the connecting steel bars pass through the small holes opened by the rubber belts and expose the wall. , Materials can use ready-made structural materials and construction techniques. It can be prefabricated and then assembled on site, or it can be cast on site. Due to the large elastic-plastic deformation of the vertical joints between the walls during the earthquake, the lateral stiffness of the shear wall is reduced, and at the same time, the staggered friction and rubber viscoelastic deformation at the interface between the vertical joints and the filled rubber can effectively dissipate the The input seismic energy achieves the purpose of good shock absorption and anti-seismic.
Description
The utility model relate to a kind of be used for construction work can reduce earthquake to the structural damage and the seismic energy that dissipates, thereby play the wall of antihunt action.
Wall is a requisite member in the construction work, can adopt different structure and material built on-site, also can pre-preparation use.
Along with developing rapidly of modern high-rise building, reinforced concrete wall becomes the structural element of extensive utilization, and reinforced concrete wall is called shear wall on specialty, and it is compared with reinforced concrete post and other wall has many advantages such as firm, durable, that anti-seismic performance is good.But because the reinforced concrete wall lateral rigidity is bigger, free vibration period of structure is shorter, and the geological process power of being born when earthquake is also bigger.Some live through the shear wall of shake doughtily, the effect of tension and compression repeatedly that caused by earthquake, and the walls concrete sheet peels off, and vertical muscle is buckled, and causes the heavy damage of body of wall.Because body of wall is main supporting member, is difficult to be repaired after being destroyed.
The purpose of this utility model be to design a kind of have can reduce geological process, and the dissipation earthquake inputs to the energy of structure, destroys and alleviates the body of wall of destruction thereby make himself to exempt from.
In order to achieve the above object, the utility model is realized by following scheme: seismic structural wall, earthquake resistant wall comprises concrete, wall reinforcement, its structural feature is: suitable position is offered perps in concrete wall, filled rubber band between perps, rubber strip is provided with 2-3 to aperture, connecting reinforcement passes aperture and exposes body of wall, and each is corresponding fixed respectively only to need connecting reinforcement, the wall reinforcement that will expose during on-site consolidation, can earthquake-resistant shear wall.
Body of wall of the present utility model is under the wind-force effect and under the service load, work as common solid concrete wall, and under the violent earthquake effect, the perps position produces bigger elastic-plastic deformation between body of wall, reduce the lateral rigidity of shear wall, thereby reduce the geological process that total is born, reduce the absorption of structure seismic energy.Simultaneously, in seismic process, the seismic energy that the changing of the relative positions friction at body of wall and filled rubber interface, rubber viscoelastic strain will dissipate and be imported effectively between perps reaches the purpose of damping antidetonation.
The utlity model has following advantage:
1. the power consumption position that is provided with perps and is filled with the body of wall of rubber strip can evenly distribute along the metope height, has avoided the body of wall bottom to concentrate the unfavorable situation of cracking power consumption;
2. the utility model construction construction technology is simple, and equipment needed thereby, material can utilize ready-made structural meterials and construction technology;
3., also have body of wall as defence line, second road, thereby improved the safety reliability of structure even moderate finite deformation and damage take place at perps power consumption position;
4. reparation aspect after the earthquake is owing to destroy connecting portion that perps on the body of wall takes place rather than in the body of wall bottom, so reparation and reinforce much relatively easy.
Accompanying drawing is embodiment of the present utility model

Fig. 2 is a rubber strip structural representation of the present utility model
Fig. 3-1 is a wall scroll seam scheme of installation of the present utility model
Fig. 3-2 is many seam scheme of installations of the present utility model
The utility model is made up of the aperture 5 on concrete 1, wall reinforcement 2, rubber strip 3, connecting reinforcement 4, the rubber strip 3.
By the prefabricated the utility model of designing requirement, make template earlier, then colligation wall reinforcement 2 and make wall segment arrangement of reinforcement 2 two ends expose body of wall in template as Fig. 1; Reserve 1-3 bar perps; Rubber strip 3 is put into the perps (width of rubber strip 3 determines that by calculating be generally 20～40mm, thickness is identical with shear wall thickness) of reservation; Connecting reinforcement 4 passes the aperture 5 of rubber strip 3 and exposes template; Fluid concrete in template is made the utility model then.Connecting reinforcement 4 and wall reinforcement 2 that prefabricated the utility model exposes are distinguished corresponding fixed on-site consolidation to building, use the concrete filling chink at last, make seismic structural wall, earthquake resistant wall of the present utility model.
But the utility model body of wall can prefabricated also field fabrication, and field fabrication and prefabricated technological process are basic identical, and its manufacturing process is: colligation wall reinforcement 2; Rubber strip 3 is put into the predetermined perps of offering (width of rubber strip 3 determines that by calculating be generally 20～40mm, thickness is identical with shear wall thickness); Connecting reinforcement 4 passes the aperture 5 of rubber strip 3 and fixed with post and floor; Make wall form; Concreting 1 because rubber strip 3 thickness are identical with shear wall thickness, when inside and outside wall plaster, is handled with general body of wall equally, and external surface does not stay any vestige.
The utility model has been applied to equipment limited company of YT Telecom dwelling house for staff and workers, 20 story shear wall constructions, building area 16009m
2No.1 Inst., Ministry of Posts and Telecommunications.'s dwelling house for staff and workers (Shanghai), 20 story shear wall constructions, building area 16009m
