Background technology
Traditional cast-in-place building refers to carry out the construction such as reinforcing bar colligation, formwork supporting plate, casting concrete at the construction field (site) to form
Building.The past for quite a long time, cast-in-place building solves personnel's employment etc. to receiving surplus rural labor force of China
Serve positive, current cast-in-place mode still occupies absolute main flow in China's construction.But, it is cast-in-place for a long time to build
Build and be widely present in constructing situ wet operation amount greatly, labour's input amount is big, and labor strength is high, poor working environment, mould
The input amounts such as plate, scaffold are big, turnover utilization rate is low, mechanized construction low degree, construction safety hidden danger and Frequent Accidents, relatively
The thorny problem such as work efficiency is not high and job site largely produces airborne dust, noise pollution, building waste many.These cast-in-place buildings
Congenital drawback is incompatible with the trend of the current construction industry development of China.
Assembled architecture is, in plant produced, to be assembled building subassembly and component and fitting at the construction field (site) and be formed by connecting
Building.It with modern science and technology is support that the construction of assembled architecture is, with industrialized production as means, with engineering
Mesh management innovation is core, and building products production overall process is coupled integral by extensive utilization information technology, intelligent environment protection technology
Change the structural system of industrial chain, assembled architecture can economize on resources and be polluted with the energy, reduction, effectively improves labor productivity,
Improve construction quality etc..The house for meeting China " 13 " national development stage " energy and land saving " and " structure industrial system " is produced
Industry guiding theory, with significant economic benefit and social benefit.The current desalination along with China human mortality bonus, it is of the right age to build
The reduction of industry number of employees is built, development assembled architecture is brought into schedule in good time.
Assembled architecture presses structural system, is broadly divided into assembled frame-shear structure, fabricated shear wall structure, assembled frame
Frame-shear wall structure etc..Wherein first two structural system is relatively more in the research of China, and both at home and abroad to assembling frame-
The research of shear wall structure is also relatively fewer, and existing research is concentrated mainly on theoretical and numerical simulation aspect, wherein H. A.
D. Samith Buddika etc. have carried out theoretical research based on Opensees softwares to assembled frame shear structure.Dionysios
Bournas etc. has carried out pseudo to 1 three layers of assembled frame shear structure model, have studied structural model different parts,
Damaged situation of the node of multi-form under geological process.Majid Divana etc. with nonlinear static force method to difference across number and
The assembled frame shear structure of floor height has carried out theoretical research.Current developing rapidly in China, assembled with building industrialization
The application of frame shear wall structure is increasing, therefore is necessary to further investigate it.
At present, the common practice to shear wall position in assembled RC frame shear structures is using traditional complete cast-in-place mode
Shear wall is built, this is mainly based upon in frame shear wall structure, shear wall as main lateral resistant member, in earthquake
In undertake most horizontal force, while shear wall is destroyed at first as the first line of defence in earthquake, thus shear wall from
The anti-seismic performance quality of body is most important.For the requirement of shear wall aspect of performance, the present patent application scheme proposes a kind of dress
With precast shear wall-composite beam connection method in formula RC frame shear structures.
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the invention provides pre- in a kind of assembled RC frame shear structures
The connection method of shear wall-composite beam processed.
Technical scheme：The connection method of precast shear wall-composite beam in a kind of assembled RC frame shear structures, including it is as follows
Step：
1）First the support of assembling shear wall, assembles the Column border node of shear wall, and wall beam is provided with shear wall, thereon with flaccidity of tendon and muscle muscle,
After the completion of support, stirrup on full grout sleeve and beam is loaded onto on the vertical muscle at shear wall Column border node, afterwards, then lift and be coated with
The composite beam of upper longitudinal bar, leveling, support are carried out by composite beam, screw the pre- full grout sleeve put, and make connected vertical muscle equal
It is even to be distributed in inside full grout sleeve, after the completion of connection, colligation stirrup, rear pouring concrete is poured, conserved；
2）Carried out sitting slurry operation with cement mortar, i.e., with cement mortar by prefabricated post top layer by being connected that full grout sleeve is formed
Position is closed, and joint face is formed closed cavity；
3）Sitting slurry carries out cementing operations after 1 day, mix is carried out in strict accordance with high-strength cement base grouting material product operation instruction before grouting
Grouting material；
4）Stirrup on the outside of shear wall at the post-cast strip of composite beam need to be encrypted, enough with the shearing strength for ensureing beam-ends
Greatly, do not destroyed first in earthquake.
As optimization：Before formal assembling, first dabbing treatment will be carried out at rear pouring concrete faying face, water under high pressure is used after dabbing
Floating dust is rinsed well.
Beneficial effect：Integral construction of the present invention is easy, is connected firmly, and anti-seismic performance is good, construction cost saving, construction period
