Abstract
Assembly integrated precast concrete shear wall and job practices, shear wall cross section in the prior art, volume and weight are bigger, and difficulty is bigger in prefabricated, transportation, lifting installation process, is not suitable for the fabricated construction worker method of housing industrialization.Assembly integrated precast concrete shear wall and job practices, its composition comprises: one group precast concrete short-limb shear wall provided (1), described precast concrete short-limb shear wall provided by connector (2) connection.The present invention is used for the assembly integrated precast concrete shear wall structural system of housing industrialization.
Description
Technical field:
The present invention relates to precast concrete design and construction field, particularly a kind of assembly integrated precast concrete shear wall structural system that is suitable for housing industrialization.
Background technology:
Concrete shear wall with short piers is meant that the wall limb depth of section and the ratio of thickness are 5～8 seismic structural wall, earthquake resistant walls, according to the current Chinese code of practice requirement, wall section thickness is not less than 200mm, and the stress performance of concrete shear wall with short piers structure is between hetermorphiscal column and general shear wall structure.Because this structural system has good performance in many-sides such as building, structure, construction cost, energy-conserving and environment-protective, has now become the form of structure that is suitable for dwelling construction most.The original form of construction work of an on-the-spot template, assembling reinforcement, cast-in-place concrete is also adopted in the construction of concrete shear wall with short piers structure at present, after main structure construction finishes, also to carry out loaded down with trivial details work such as a large amount of interior and exterior finishes, equipment installation installation, make that construction cost is big, site operation program and complex management, and the final structure construction quality also is difficult to obtain assurance.The comprehensive energy consumption of original in addition form of construction work building structure is higher, and construction mode is unfavorable for environment and energy-conservation, and the construction place is not easy to clean, construction noise seriously disturbs residents.Therefore in housing industrialization, adopt precast concrete short-limb shear wall provided structure Design method and construction, can remove all disadvantages of original form of construction work, make the advantage of short-shear wall structure to give full play to.
But according to China's code requirement, can not all adopt shear wall with short piers by all bodies of wall in the short-shear wall structure, must be furnished with the general shear wall of some, be wall limb depth of section with the ratio of thickness greater than 8 seismic structural wall, earthquake resistant wall, because the cross section of such body of wall, volume and weight are bigger, difficulty is bigger in prefabricated, transportation, lifting installation process, just is not suitable for the fabricated construction worker method of housing industrialization.
Summary of the invention:
The purpose of this invention is to provide a kind of assembly integrated precast concrete shear wall and job practices, structural performance is reliable, helps environmental protection and energy saving.
Above-mentioned purpose realizes by following technical scheme:
Assembly integrated precast concrete shear wall, its composition comprises: one group precast concrete short-limb shear wall provided, described precast concrete short-limb shear wall providedly connect by connector.
Described assembly integrated precast concrete shear wall, described precast concrete short-limb shear wall provided wall limb depth of section is 5-8 with the ratio of thickness, wall limb cross sectional shape is in-line or T font or L shaped or cross.
Described assembly integrated precast concrete shear wall, described connector are that interface shearing-resistance connector or the reserved steel bar that passes through described precast concrete short-limb shear wall provided both sides adopt the vertical ater-casting of reserving to connect.
Described assembly integrated precast concrete shear wall, described interface shearing-resistance connector welds mutually with the shear reinforcement of precast concrete short-limb shear wall provided inside.
Described assembly integrated precast concrete shear wall is describedly reserved gingival cyst of mucous gland in the newborn stubble slit between precast concrete short-limb shear wall provided, and irritate having grouting to expect in described gingival cyst of mucous gland in the newborn stubble the slit in.
The job practices of assembly integrated precast concrete shear wall, described precast concrete short-limb shear wall provided prefabricated in factory in advance, maintenance is finished after be transported to the job site by haulage device, the site assembly formula construction that adopts lifting machine to lift during construction.
Beneficial effect of the present invention:
1. the invention provides a kind of assembly integrated precast concrete shear wall structural system that is suitable for housing industrialization, this structural system has that the building course switching performance is reliable, construction is advanced, construction quality is easy to guarantee, structure tension performance satisfies the characteristics of existing national regulation requirement fully, the present invention is on-the-spot basic for doing operation, has fully avoided all disadvantages of original form of construction work.Help environmental protection and energy saving, be suitable for extensive construction, help reducing construction cost, save construction fund.
The present invention's ratio that cross section, general shear wall that volume and weight is bigger are divided into wall limb depth of section and thickness be 5～8 precast concrete short-limb shear wall provided, assembling at the construction field (site) is prefabricated in the factory, each is precast concrete short-limb shear wall provided to adopt interface shearing-resistance connector to connect each other, so just can carry out prefabricated, transportation and lifting construction according to the fabricated construction worker method that is suitable for housing industrialization.Owing to complicated procedures of forming such as a template of having cancelled original form of construction work, assembling reinforcement, fluid concretes, therefore make site operation environment and condition improve greatly, speed of application is accelerated greatly, and prefabricate structural portion product specification unanimity, quality are unified, and the construction quality of building structure can access sufficient assurance.
