Description
Technical field
The present invention relates to a kind of laminated column frame compound shear wall, particularly a kind of shaped steel folding frame post built-in " many steel plates-support " compound shear wall and the practice.
Background technology
Current fast development of society, highrise building and super highrise building are more and more.The steel concrete highrise building is made up of beam, post, floor and shear wall and cylindrical shell usually.Shear wall and be the core of highrise building antidetonation by the cylindrical shell that shear wall is formed, the anti-seismic performance of shear wall structure has crucial effects for highrise building safe and reliable.Particularly in recent years, the large complicated highrise building of pursuing individualityization is increasing, and the anti-seismic performance that shear wall is reached the cylindrical shell of being made up of shear wall requires also increasingly high.Existing reinforced concrete shear wall ductility under geological process is relatively poor, easy brittle destruction af-ter, and this is very unfavorable to integrally-built anti-seismic performance.
Steel tube concrete superposed column is a kind of vertical lateral resistant member that grew up in recent years.Superposed column is formed by core high strength concrete filled steel tube and peripheral reinforced concrete sandwich.Through core concrete filled steel tube and peripheral concrete construction by stages, make superposed column have the ratio of axial compressive force to axial compressive ultimate capacity of section height of core concrete filled steel tube, the low characteristics of ratio of axial compressive force to axial compressive ultimate capacity of section of peripheral concrete.Adopt superposed column can realize big ratio of axial compressive force to axial compressive ultimate capacity of section, thereby reduce the sectional dimension of post, increase the usable floor area of building, obtain favorable economic benefit, can also improve the anti-seismic performance of post simultaneously largely.Although steel tube concrete superposed column has energy dissipation capacity preferably, when it during as the frame columns of shear wall, because reinforced concrete wall panel is relatively poor as the first line of defence ductility in the shear wall, has been influenced whole shear wall so that the lateral resisting of total.
Summary of the invention
Technical problem to be solved by this invention is how to significantly improve the technical problem of frame ductility of sheer wall, energy dissipation ability.In order to address this problem, the present invention proposes built-in " many steel plates-support " compound shear wall of a kind of shaped steel folding frame post and corresponding preparation method.
The present invention has taked following technical scheme:
Shaped steel folding frame post built-in " many steel plates-support " compound shear wall; It is characterized in that: shaped steel folding frame post is set at the body of wall two ends; Add in the inner many steel plates of body of wall and join dark supporting steel plate; In the shaped steel folding frame post at shear wall two ends steel tube concrete core pillar is set, steel tube concrete core pillar is a rectangle; Shaped steel folding frame post constitutes through set up steel tube concrete core pillar at the center of conventional concrete column; Shear wall comprises three block plates; The dark supporting steel plate of diagonal cross is set respectively between middle steel plate and outside steel plate, and dark supporting steel plate is crossed as the X font, directly passes steel tube concrete core pillar; Its upper end is stretched in the upper side frame beam, and the lower end is stretched in the lower frame beam.
Said dark supporting steel plate is the mild-steel energy-consumption steel plate.
Middle steel plate is the vertical steel plate bar of welding on the steel pipe of steel tube concrete core pillar with outside steel plate and being connected of steel tube concrete core pillar in the said body of wall, and middle steel plate and outside steel plate are welded with vertical steel plate bar again.
Described dark supporting steel plate is the steel pipe that dark supporting steel plate directly passes steel tube concrete core pillar with being connected of steel tube concrete core pillar, is welded with it then.
According to technical scheme of the present invention, adopt the preparation method of shaped steel folding frame post built-in " many steel plates-supports " compound shear wall, its in proper order as follows:
1) make shaped steel folding frame post and steel tube concrete core pillar, the vertical steel plate bar of prewelding on the steel pipe walls of steel tube concrete core pillar is in order to middle steel plate and outside steel plate anchoring;
2) middle steel plate of configuration shear wall, and with the steel pipe walls of steel tube concrete core pillar on the vertical steel plate bar welding of prewelding;
3) dispose dark supporting steel plate respectively in the middle steel plate both sides, dark supporting steel plate is crossed as the X font, directly passes steel tube concrete core pillar, and its upper end is stretched in the upper side frame beam, and the lower end is stretched in the lower frame beam;
4) in dark supporting steel plate both sides, configuration outside steel plate, and with the steel pipe walls of steel tube concrete core pillar on the vertical steel plate bar welding of prewelding;
5) reinforcing bar of colligation shear force wall reinforcing steel bar concrete lower frame beam; And in the reinforcing cage with shaped steel folding frame post, middle steel plate, dark supporting steel plate insertion lower frame beam; The concrete of cast lower frame beam; After concrete curing is fixed, make the bottom of middle steel plate in lower frame beam and shaped steel folding frame post, steel tube concrete core pillar, the shear wall realize being rigidly connected;
6) make the upper side frame beam, reliably be connected with shaped steel folding frame post, outside steel plate and middle steel plate and dark supporting steel plate;
7) protective layer thickness is stayed in the shaped steel folding frame post outside, a template;
8) carry out the concrete in the steel tube concrete core pillar, concrete, shear wall and upper side frame beam concrete and the inner concreting of lower frame beam of shaped steel folding frame post inside, be shaped steel folding frame post built-in " many steel plates-support " compound shear wall after the moulding.
Among the present invention; As many steel plate concretes shear wall slab part of antidetonation the first line of defence, its built-in dark supporting steel plate is very favourable to the shear-carrying capacity, ductility and the energy dissipation capacity that improve shear wall, also is beneficial to shear wall and the two Load Redistribution of bearing of shaped steel folding frame post; A part of pressure transfer that shear wall is born is in shaped steel folding frame post; Reduce the ratio of axial compressive force to axial compressive ultimate capacity of section in the shear wall, thereby make thinner that shear wall can design, increase the usable floor area of building.After shear wall slab destroys in antidetonation; The trussed construction that steel tube concrete core pillar in dark supporting steel plate and upper and lower frame beam, the shaped steel folding frame frame columns forms is a geometrically stable system; Steel truss self can form good force transfer system, thereby keeps the resistance to overturning of structure.Compare with common steel tube concrete frame shear wall, supporting capacity improves, and bearing capacity and stiffness degradation are slack-off, and the later stage anti-seismic performance is relatively stable, and the bottom shear sliding rupture alleviates.
Because shear wall is the core lateral resisting parts of building structure, has improved the shock resistance of shear wall, has also just improved the whole shock resistance of structure, when building meets with violent earthquake, can alleviate its earthquake, prevent that it from collapsing.
