Description
Technical field
The utility model is a kind of Z type cross section single-row reinforcement concrete shear wall structure with the intersection diagonal bar, belongs to the shear wall structure field.
Background technology
Since the violent earthquake of Wenchuan, the anti-seismic performance of multi-storey building structure more and more obtains paying attention to.After the loam brick multi-storey building is disabled, Chinese scholars has been studied some novel multi-layer residential structures, as small concrete block masonry structure, Framed Structure with Special-Shaped Columns, light section steel structure, single-row reinforcement concrete shear wall structure, yet this new structure still exists many defectives.Globality and the anti-seismic performance of masonry structure dwelling house are relatively poor, quality problems such as " heat, split, ooze, thoroughly " occur easily; Problems such as the indoor leakage beam leakage of frame construction dwelling house post, room irregularity are serious; The light section steel structure cost is higher, and fire line and the durability of structure are relatively poor; And the ductility of shear wall is relatively poor, has influenced the performance of its whole anti-seismic performance.It is to adapt to greatly develop building energy conservation, development green building material in China's housing construction that band intersects the single-row reinforcement concrete shear wall structure dwelling house of diagonal bar, advances the new situations of body of wall innovation and the novel building energy-saving structure system that proposes.It is the new structure of a kind of suitable multi-storey building of growing up on the basis of single-row reinforcement shear wall structure, it has given full play to the advantage of single-row reinforcement shear wall structure, cross bar can limit and postpone diagonal crack to the development of main diagonal crack, increased plastic hinge power consumption region height, thinner and close and range of distribution is wide than common shear wall crack, destructiveness is lighter, and bearing capacity and stiffness degradation are slow, the later stage anti-seismic performance is more stable, and it also has advantages such as the cross section is little, in light weight, cost is low simultaneously.Therefore compare with bidirectional single-row reinforcement shear wall, can under the prerequisite of identical reinforcement ratio, improve the anti-seismic performance of shear wall greatly.
The utility model content
At the deficiency of above-mentioned reinforced concrete shear wall, problem to be solved in the utility model is:
Compare with common single-row reinforcement shear wall, under the prerequisite that does not change the wall reinforcement rate, improve the anti-seismic performance of shear wall.
For this purpose, the utility model proposes the single-row reinforcement concrete shear wall structure of band intersection diagonal bar.Under the prerequisite that does not change the wall reinforcement rate, in body of wall, arrange to intersect diagonal bar, spend angles with 4 one-tenths 60 degree of horizontal distribution reinforcing bar and 45, suitably adjust distribution reinforcement and intersect the ratio of diagonal bar, the anti-seismic performance of shear wall is improved.
The technical scheme that the utility model band intersection diagonal bar single-row reinforcement concrete shear wall structure adopts is:
Be with the single-row reinforcement concrete shear force wall of intersection diagonal bar, between basis 8 and dark beam 7, include the vertical muscle 2 of sleeper, sleeper stirrup 3, sleeper 1, horizontal distribution reinforcing bar 4, vertical distribution reinforcement 5, intersection diagonal bar 6 and concrete cover 9; 3 colligations of sleeper stirrup form sleeper 1 at the vertical muscle 2 of sleeper, sleeper 1 places wall limb both sides and node place as wall limb edge member, horizontal distribution reinforcing bar 4 is lateral buckling outside shear wall node place walks around the vertical muscle 2 of sleeper, development length after the bending is greater than 15 times of the bending bar diameter, vertically distribution reinforcement 5 forms steel mesh reinforcement with the 4 vertical colligations of horizontal distribution reinforcing bar, intersect diagonal bar 6 in the steel mesh reinforcement disposed inboard, shear wall adopts the single-row reinforcement mode of band intersection diagonal bar 6,4 one-tenth 60 degree of diagonal bar 6 and horizontal distribution reinforcing bar or 45 that intersect are spent angles, become " X " type in the wall limb.
Described band intersects the diagonal bar shear wall, and the wall section form is the Z font, wall limb web be furnished with 4 one-tenths 60 degree of horizontal distribution reinforcing bar angle intersect diagonal bar 6, one-tenth " X " type in the wall limb; Bottom, the edge of a wing 1/3 wall limb is furnished with horizontal distribution reinforcing bar 4 intersection diagonal bar in angle of 45 degrees, becomes evenly to arrange.Intersection diagonal bar upper end extend into anchorings in sleeper 1 and the dark beam 7, and the distance of lower end from shear wall wall limb bottom surface apart from the wall external surface is that thickness of concrete cover 1 stretches into basic anchoring.
The single-row reinforcement concrete shear force wall of described band intersection diagonal bar, the intersection diagonal bar 6 that disposes is symmetric reinforcement; Wall podomere point and end sleeper stirrup 3 forms are rectangle and triangle; Wall podomere point and end sleeper 2 place's reinforcing bar processing methods are: horizontal reinforcement is walked around lateral buckling outside the sleeper reinforcing bar at shear wall node place, and the development length after the bending is greater than 15 times of the bending bar diameter; Sleeper stirrup 3 below 1/3 length adopt the stirrup encryption.
The utility model can obtain following beneficial effect:
The utility model has been given full play to the advantage of single-row reinforcement shear wall structure, the diagonal bar that intersects can limit and postpone diagonal crack to the development of main diagonal crack, increased plastic hinge power consumption region height, thinner and close and range of distribution is wide than common shear wall crack, destructiveness is lighter, and bearing capacity and stiffness degradation are slow, and the later stage anti-seismic performance is more stable, therefore compare with bidirectional single-row reinforcement shear wall, can under the prerequisite of identical reinforcement ratio, improve the anti-seismic performance of shear wall greatly.
The single-row reinforcement concrete shear wall structure of band intersection diagonal bar has been broken through the concrete shear force wall reinforcement manner that is applicable to high building structure at present, its anti-seismic performance is good, the shearing slip that can stop the shear wall bottom effectively, the restriction body of wall is sheared diagonal crack and is carried out, bearing capacity, ductility and the energy dissipation capacity of shear wall have been improved, simultaneously it has also that the cross section is little, in light weight, cost is low, construction technology is simple, and the cost performance advantages of higher is suitable for multi-layer construction structure.
