Abstract
The invention discloses a self-thermal-insulation laminated slab type shear wall with built-in hidden supports. The shear wall comprises precast concrete layers, a thermal insulation plate, a cast-in-situ concrete layer, transverse steel bars, vertical steel bars, lattice steel bars, stirrups, U-shaped joint bars, a foundation beam and diagonal stiffeners (the hidden supports). The lattice steel bars are welded to the vertical steel bars located on one side, then are pressed into another precast concrete layer, and mainly play roles in enabling the precast concrete layers to be connected and enabling a laminated layer and the cast-in-situ concrete layer to operate collaboratively; the U-shaped joint bars are located at the bottom of the shear wall and enable the foundation beam and a wall body to be stressed collaboratively; the thermal insulation plate is arranged between the laminated layer and the cast-in-situ concrete layer and can improve the thermal insulation performance of the wall body. The diagonal stiffeners (the hidden supports) are welded to a steel bar framework formed by the transverse steel bars and the vertical steel bars to enhance the shearing resistance of the wall body under the earthquake action and meanwhile enable the foundation beam and the wall body to be stressed collaboratively.
Description
Technical field
The present invention relates to a kind of building structural element, particularly the shear wall in superimposed board-like structural building, belongs to building structure technology field.
Background technology
At present, what most reinforced concrete structure adopted is cast-in-place structural, and it has advantages of, and anti-seismic performance is good, plasticity is good, good integrity etc.Also have some shortcomings, such as site operation intensity is large, construction period is longer, the degree of suitability for industrialized production is low simultaneously, and template consumption is large, and seasonal effect is comparatively obvious etc.Another kind of correspondingly be exactly prefabricated reinforced concrete structure, part building unit can suitability for industrialized production, manufacture be subject to seasonal affect little, short construction period, the use of template is few, but maximum shortcoming is that overall performance is poor, is unfavorable for antidetonation, in all previous earthquake, find that the destruction of prefabricated units is comparatively serious.So, in antidetonation area, be that prefabricated assembled member is used in restriction.In addition, precast reinforced concrete construction is not impervious, so can not be for special construction.
In addition, Chinese patent discloses the superimposed board-like shear wall of a kind of " one " font for " 200920299378.0 " number, and its design feature is: be between two facing-wall boards of contiguous prefabricated superimposed board-like shear wall perps junction, to be provided with antidetonation post: form imperforation wallboard splicing shear wall.This kind of seismic structural wall, earthquake resistant wall is to a kind of improvement of traditional shear wall, but this patent can not solve common three kinds of earthquakes of reinforced concrete shear wall: 1. on metope, occur oblique crack; 2. the horizontal construction joint occurred level changing of the relative positions of bottom floor; There is too early shear failure in the coupling beam 3. joining in limb shear wall.
Summary of the invention
The present invention proposes the superimposed board-like shear wall of a kind of built-in dark support self-heat conserving, make full use of the advantage of monolithic reinforced concrete structure and prefabricated reinforced concrete structure, overcome the shortcomings such as cast-in-place concrete structure long construction period, template consumption is large, labour intensity is large, can solve the problem of fabricated construction poor seismic behavior again simultaneously.
The technical solution used in the present invention is: the superimposed board-like shear wall of a kind of built-in dark support self-heat conserving, comprises precast concrete layer, warming plate, cast-in-situ concrete layer, transverse reinforcement, vertical reinforcement, lattice reinforcing bar, stirrup, U-shaped joint bar, grade beam and diagonal bar (secretly support);
Described precast concrete layer, warming plate, cast-in-situ concrete layer are joined together to form body of wall, cast-in-situ concrete layer is arranged between two precast concrete layers, described warming plate is placed between precast concrete layer and cast-in-situ concrete layer, improve the heat-insulating property of body of wall, described transverse reinforcement, vertical reinforcement and lattice reinforcing bar are arranged in body of wall, lattice reinforcing bar and vertical reinforced-bar-welding, lattice reinforcing bar mainly plays connection preformed layer, makes overlapping layers and in-situ layer collaborative work;
In described grade beam, be provided with transverse reinforcement and stirrup;
Described body of wall is arranged on grade beam, and described U-shaped joint bar is positioned at grade beam bottom, and stretches in body of wall, makes grade beam and body of wall cooperative bearing; Described diagonal bar is welded on the cage of reinforcement of transverse reinforcement and vertical reinforcement composition, not only can strengthen wall shear resistant under geological process, makes grade beam and body of wall cooperative bearing simultaneously.
As preferably, described transverse reinforcement, vertical reinforcement, lattice reinforcing bar, stirrup, U-shaped joint bar, diagonal bar are that common hot-rolled reinforced bar processes.
As preferably, described warming plate 2 is the concrete insulation board of regenerated polystyrene foam (REPS), can be also the conventional warming plate of engineering, as EPS warming plate etc.
As preferably, described precast concrete layer 1 can be the thick fine concrete of 40-60mm.
Described cast-in-situ concrete layer 3, grade beam 9 can be common commercial concrete.
Beneficial effect: 1. the present invention innovates in structural system, belong to wall self-insulation, be beneficial to the heat-insulating property that improves body of wall, and heat insulating material regenerated polystyrene foam (REPS) concrete insulation board turns waste into wealth, meet the requirement of green building and environmental protection.Foam concrete heat-preserving plate realize building energy conservation more than 65% in, guarantee building fire safety and application life.It has been trend of the times that foam concrete heat-preserving plate replaces organic insulation material (as EPS plate) in building energy conservation, and market progressively expands.Foam concrete be take cement as major ingredient, is secure and non-combustible material, and fire-resistant level is greater than 2h, can reach A level fire-protection standard, can meet the fire protection requirement of any building completely.Be generally 50-100 the projected life of building.Foam concrete durability is greater than 50 years, can with building the same life-span.
2. the present invention proposes the superimposed board-like shear wall of built-in dark support self-heat conserving, make full use of the advantage of monolithic reinforced concrete structure and prefabricated reinforced concrete structure, overcome the shortcomings such as cast-in-place concrete structure long construction period, template consumption is large, labour intensity is large, can solve the problem of fabricated construction poor seismic behavior again simultaneously.And compared to No. " 200920299378.0 ", Chinese patent, this adds bearing capacity and ductility that the superimposed board-like shear wall of dark support can improve shear wall effectively, carrying out of restriction shear wall diagonal crack, postpone the appearance of shear wall bottom plastic hinge, structural entity resistant function is lasting, rigidity and bearing capacity decay are slow, the stable performance of structure later stage, and whole anti-exhibition ability strengthens.
