Description

A kind of compound shear wall
Technical field
The invention belongs to the technical field of structural engineering in the civil engineering industry, relate to a kind of compound shear wall.
Background technology
At present, the composite class shear wall mainly comprises the compound shear wall of steel plate external wrapping concrete compound shear wall, one-sided steel plate-concrete combined shear wall, band i iron frame etc.This type of combined shear body of wall makes full use of the buckling strength and the concrete compressive strength of steel plate mainly through the combination between steel and the concrete, reaches the ductility and the energy dissipation capacity that improve seismic shear wall.But above-mentioned seismic shear wall body is mainly used in the newly-built building structure.For existing building, run into raising that storey-adding reconstruction or seismic design require etc. through regular meeting, thereby cause the anti-side rigidity of existing building structure not meet the demands, need set up the shear wall of some during reinforcing design for this reason.
Based on 5.12 earthquake field investigation results in 2008, the infilled wall of frame construction played tangible contribution to the anti-side rigidity that improves frame construction, under horizontal force action, was prone to generation X-shaped crack, destroyed out-of-plane collapsing to be taken place when serious.
In addition, sharply descend along with being engaged in simple blue-collar number of workers on China building site, labor cost also improves gradually.Therefore, be necessary to develop a kind of level opposing supporting capacity, easy construction that can improve frame construction, can make full use of the novel combination shear wall of existing masonry infilled wall again.
Summary of the invention
Technical problem:The invention provides and a kind ofly be applicable to existing multistory frame structure, can improve wall ductility, be convenient to install, reduce the compound shear wall of construction cost.
Technical scheme:Compound shear wall of the present invention; Comprise allowable ratio of height to sectional thickness of masonry wall or column, be arranged on peripheral steel plate band and steel plate diagonal brace on allowable ratio of height to sectional thickness of masonry wall or column two facades; Four limits of periphery steel plate band allowable ratio of height to sectional thickness of masonry wall or column facade along the place are provided with, and the peripheral steel plate band of two adjacent edges connects, and forms a steel plate framework; The diagonal angle of steel plate framework connects through the steel plate diagonal brace, between the relative peripheral steel plate band in allowable ratio of height to sectional thickness of masonry wall or column both sides, connect by the split bolt that passes allowable ratio of height to sectional thickness of masonry wall or column between the steel plate diagonal brace.
Among the present invention, the thickness of peripheral steel plate band and steel plate diagonal brace is 3 ~ 30mm.
Among the present invention, between peripheral steel plate band and the steel plate diagonal brace through being welded to connect.
Among the present invention, allowable ratio of height to sectional thickness of masonry wall or column is that common solid or building-block and the binding material of thickness 120 ~ 370mm built the infilled wall that forms by laying bricks or stones.
Among the present invention, spacing is 200 ~ 400 times of steel plate thickness between the two adjacent split bolts.
Among the present invention, the diameter of split bolt is 10 ~ 30mm.
Beneficial effect:The present invention compares with prior art, has the following advantages:
1. steel plate belongs to ductile material, possesses higher energy dissipation capacity; After steel plate and masonry make up through split bolt; Allowable ratio of height to sectional thickness of masonry wall or column can improve the buckling strength of steel plate effectively through lateral restraint; Steel plate diagonal brace, peripheral steel plate band form certain constraint to masonry wall; Can improve the ductility ability of body of wall, both combinations can increase the ductility and the energy dissipation capacity of shear wall better.
2. at the scene the work progress, existing frame construction is connected in compound shear wall of the present invention and the building, and the allowable ratio of height to sectional thickness of masonry wall or column in the compound shear wall can be for building or utilize existing masonry infilled wall by laying bricks or stones again.Therefore, in the seismic hardening of multistory frame structure is transformed, can utilize existing framework and infilled wall fully.
3. compound shear wall of the present invention can adopt welding and split bolt assembled by producing good steel plate diagonal brace, peripheral steel plate band and masonry filled wall in the factory at the construction field (site).Therefore, the related wet trade of the whole process of production of this compound shear wall is few and the duration short, can reduce the personnel amount and the human cost of work, and allowable ratio of height to sectional thickness of masonry wall or column is built by laying bricks or stones or assembly unit that existing infilled wall, bolt are connected with weld seam can the reduction of erection time for on-the-spot simultaneously.
4. the steel plate diagonal brace that is adopted, peripheral steel plate band and split bolt are in factory, to carry out mechanization production, can realize that mechanization produces in batch, and production efficiency is high, reduces the noise and the environment pollution of job site simultaneously;
5. light plate of the present invention-masonry assembled wall possess good detachable with re-assembly characteristic, meet sustainable development idea.
