Abstract
A light slab structure of short-limb shear wall for large-bay residence is composed of shear wall, beam, floor and partition. It features that said partition may be internal partition or the partition between adjacent families, has short-limb stressed plates at intervals of at least 2m, the top and bottom ends of short-limb stressed plate is connected with upper and lower beams to form a whole, and light non-bearing slabs are used in other spaces. Its advantages include flexible partition, large bay, low dead weight of building, high anti-earthquake performance. It is suitable for 7-25 stories of high buildings.
Description
The present invention relates to a kind of shear wall housing construction structural system.
The high residential building of existing shear wall structure, the common whole standard width of a room in an old-style house and depth all adopt the concrete shear wall structure of long limb; There are some buildings to adopt connection limb wall or wall frame to make exterior wall, interior wall adopts two limbs, many limbs or independent wall, superstructure adopts ordinary concrete girt strip superstructure or close rib prestressing force flat beam building cover scheme, but the infilled wall of party wall has still adopted structural clay tile or light block, and partition board only plays the partition effect.Be characterized in that rigidity is big, antidetonation good, but the building layout is dumb, construction costs is also higher.Existing partition board is only considered its rigidity roughly in structural calculation oneself shakes the influence in cycle to structure, has ignored the advantageous effect of dissimilar light plates to agent structure.
The purpose of this invention is to provide a kind of light slab structure of short-limb shear wall for large-bay residence, shear wall structure is combined with light plate, realize large bay, cut off flexibly, and the deadweight that alleviates building, the test of violent earthquake more can be stood.
The technical scheme of light slab structure of short-limb shear wall for large-bay residence of the present invention: comprise shear wall, beam, floor and the vertical partition wall that is connected with shear wall, it is characterized in that: vertical partition wall is internal partition wall or party wall, vertical partition wall is separated with a manomelia stressed plate between at least 2 meters, manomelia stressed plate upper and lower side and upper and lower beam are linked to be integral body, fill the non-bearing light plate at its complementary space of vertical partition wall.
Above-mentioned manomelia stressed plate is ordinary concrete plate or cast-in-place ordinary concrete plate.
The thickness of above-mentioned vertical partition wall is 120～160mm.
Above-mentioned non-bearing light plate can be selected haydite hollow core slab, haydite perlite hollow core slab, haydite slag hollow core slab or the haydite perlite slag hollow core slab of joining steel fabric sheet for use.
Between the above-mentioned non-bearing light plate, between non-bearing light plate and the shear wall, give between the plate seam of non-bearing light plate and manomelia stressed plate and boxing out, and the cement mortar that micro-expanding agent is mixed in perfusion in the hole, joint surface is obturaged with cloth and clay.
The superstructure of foregoing invention can adopt common multi-ribbed flat beam building cover.The case base can only be established or the base of turning up soil in the basis, fewly beats or does not drive piles.
The present invention is in 7 ° of seismic fortification intensities, case base situation, and different layers high building technical-economic index is as follows:
The 18 layers of Floor 12 that punches greatly standard width of a room in an old-style house 6m 6.3m 3.9m depth 15m 15m 15m post 6 * 6 6.3 * 6 3.9 * 4.5 1.19 seconds 1.15 seconds 1.1 seconds 2.7 2.7 2.7 height overall 49.5m 33.3m 19.8m basic cycles of floor height of net storey sidesway 1/,847 1/1,349 1/1180 top drift 1/1,049 1/1,662 1/1563 every m that punches greatly that punches greatly seven layers2Weight 7.92KN/m

Advantage of the present invention: 1,, can realize large bay, flexible topology, satisfy the needs of different user to greatest extent because body of wall of the present invention adopts light plate to fill; Wall surface levelling, not head beam post corner angle; The best number of plies that is suitable for is 7～25 layers.2, shock resistance doubles, and space rigidity is big, and globality improves.Experimental study shows, fill light plate after, the sidesway initial stiffness improves 4～5 times, is used for the earthquake zone soft foundation, meets the big principle of choice structure system.Ductility is good, and experimental study shows that general independent community wall ductility factor is 3-4; Connection limb wall is 6-8, and the present invention can reach 11.6～24.4; Form the beam hinge body when destroying under low cycle repetitive load, the therefore anti-ability height that collapses, light plate support the multiple performance of floor when having maintenance, damping and violent earthquake, can play the first line of defence effect of protection stereochemical structure.3, increase substantially the bearing capacity and the safety reliability of structure.4 advance reasonable disposition with common stressed plate in the vertical partition wall and non-stress plate, have reduced the span and the depth of section of flat beam in the close rib building roof, do not need to adopt the flat beam of prestressing, can adopt common multi-ribbed flat beam, have reduced the reinforcement ratio of superstructure.5, the primary structure member cross section is simple, easy construction.6, the case base can only be established or the base of turning up soil in the basis, fewly beats or does not drive piles, and has reduced foundation cost and construction costs.Generally under the identical standard situation than other concrete structure dwelling house save 100 yuan/more than the square meter.
Below in conjunction with drawings and Examples the present invention is described in detail:
Fig. 1 is the organigram of light slab structure of short-limb shear wall for large-bay residence of the present invention.
Fig. 2 is a light slab structure of short-limb shear wall for large-bay residence layout schematic diagram of the present invention.
Fig. 3 is the connected mode embodiment schematic diagram of vertical partition wall in the structure of the present invention.
As shown in the figure, light slab structure of short-limb shear wall for large-bay residence of the present invention comprises shear wall 3, beam, floor and vertical partition wall, it is characterized in that: vertical partition wall is internal partition wall or party wall, vertical partition wall is separated with a manomelia stressed plate 1 between at least 2 meters, the manomelia stressed plate is to be welded into integral body or to be linked to be integral body with cast-in-place ordinary concrete plate and last underbeam with ordinary concrete plate upper and lower side and upper beam 4, underbeam 5 in the construction.Its complementary space at vertical partition wall is filled non-bearing light plate 2, and the non-bearing light plate is selected haydite hollow core slab, haydite perlite hollow core slab, haydite slag hollow core slab or the haydite perlite slag hollow core slab of joining steel fabric sheet for use.The thickness of vertical partition wall is selected 120mm, wide selections of plate 400mm, and ratio of axial compressive force to axial compressive ultimate capacity of section＜0.6, the thickness of out-of-plane stability of manomelia stressed plate and light plate determines that its sectional dimension, thickness of slab will consider to insulate against sound and the sense organ effect.The non-bearing light plate can be selected haydite hollow core slab, haydite perlite hollow core slab, the haydite slag hollow core slab of joining steel fabric sheet 6 for use.Between the non-bearing light plate, between the pilaster of non-bearing light plate and shear wall 3, give between the plate seam of non-bearing light plate and manomelia stressed plate and box out 7, and the cement mortar that micro-expanding agent is mixed in perfusion in the hole, joint surface obturages 8 with cloth and clay.Superstructure of the present invention can adopt common multi-ribbed flat beam building cover.The case base can only be established or the base of turning up soil in the basis.
