Description
Technical field
The internal division type laminated column frame-bilayer steel plate combined concrete shear wall belongs to building field.
Background technology
Along with domestic and international high building structure is more and more, people are to the provide fortification against earthquakes research and the also attention further of heat preservation energy-saving research of highrise building.And 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.So the form of innovation shear wall, the anti-seismic performance and the heat preservation energy-saving sound insulation effect that improve shear wall also just become one of heat subject of building field.
At present in the shear wall research field, existing scholar has carried out the research of steel plate concrete shear wall, but mainly is the lateral rigidity that has improved shear wall mostly, excavates inadequately component inside material energy dissipation ability, in addition to the heat preservation energy-saving sound insulation effect of shear wall consider also not enough.
Aspect the heat preservation energy-saving effect that improves body of wall, at present a lot of schemes all are to adopt external thermal insulation system to realize.Employed material (foamed polystyrene board material, polymer bonding mortar and plastering mortar etc.) price is higher, and occur the quality technology problem easily, especially the load-bearing problem of wall external thermal insulation also is difficult to resolve and determines, and is difficult to make insulation layer to reach the reliable degree of safety and firmness.
Summary of the invention
In order to overcome the shortcoming of present building field shear wall, the utility model provides a kind of internal division type laminated column frame-bilayer steel plate combined concrete shear wall, thereby improves the anti-seismic performance and the heat preservation energy-saving effect of shear wall simultaneously.
To achieve these goals, the technical solution adopted in the utility model is:
Design a kind of internal division type laminated column frame-bilayer steel plate combined concrete shear wall, steel tube concrete superposed column and middle body of wall by two constitute, be provided with vertical right-angled intersection dividing plate in the steel pipe in the described steel tube concrete superposed column, this dividing plate is made of sheet iron, and dividing plate is provided with the friction key of equally distributed columnar protrusions shape; Comprise the double-layer plate that is connected with steel pipe in the described body of wall; Steel pipe and double-layer plate are surrounded by steel concrete outward; Also be provided with the lacing wire of passing steel plate in the body of wall.
Accompany the heat insulating and sound insulating material between described double-layer plate.
Described sheet iron thickness is below the 1mm.
Described friction key is that point is welded in screw or iron nail or the waste iron filing on the sheet iron.
Described steel bar in reinforced concrete is the encirclement steel pipe that crosses one another and the vertical muscle and the stirrup of double-layer plate.
The preparation method of internal division type laminated column frame-bilayer steel plate combined concrete shear wall is as follows:
Step 1 is placed right-angled intersection in steel pipe thickness is the sheet iron below the 1mm, and steel duct is divided into four parts, and in advance screw or iron nail or waste iron filing point is welded on the sheet iron.
Step 2 is fluid concrete in steel pipe.
Step 3 is provided with between two adjacent steel pipes by welding or riveted joint or bolt connection two-layered steel plates, and the distance between the adjacent steel pipe is decided according to the actual requirements.
The beneficial effects of the utility model: 1) adopt dividing plate that the Rectangular Concrete column section in the steel pipe is divided into 4 independently uniform section unit posts, the ratio of shear span to effective depth of section expansion of former Rectangular Concrete post in the steel pipe is twice, improve its deformability and ductility.2) establish friction key on the dividing plate, when 4 independently during the changing of the relative positions of uniform section unit post mutual extrusion, friction key just can play good power consumption effect, thereby reduces the influence of geological process to shear wall.3) can add the heat insulating and sound insulating material between steel plate, improve the anti-seismic performance and the heat preservation energy-saving sound insulation effect of shear wall so simultaneously.4) concrete around the steel pipe can play the fireproof effect in the superposed column, reduces the interim suffered influence of shear wall frame of fire.

The specific embodiment
Below in conjunction with accompanying drawing 1-4 a kind of embodiment of the present utility model is illustrated.
At first, determined the size and the position of inner each ingredient of shear wall according to the functional requirement of shear wall stressing conditions and the sound insulation of required heat preservation energy-saving.
At shear wall body of wall 1 both sides correct position steel tube concrete superposed column 2 is set as required, when pouring into a mould the concrete in the steel pipe 3, adopts right-angled intersection dividing plate 4 that the Rectangular Concrete column section in the steel pipe is divided into 4 independently uniform section unit posts.Right-angled intersection dividing plate employing thickness is 0.5 millimeter sheet iron, and the many screws of spot welding are as friction key 12 on the sheet iron.
Next welded steel double steel plate 5 is set between steel pipe, and 5 of double-layer plates add required heat insulating and sound insulating material 7, adopt polystyrene foam plastics here.Steel plate thickness and spacing can be adjusted according to the needs of actual antidetonation needs and reinforcement heat preservation energy-saving sound insulation effect.Have the reserving hole 6 of enough sizes and quantity on the double-layer plate 5, pass so that connect the concrete lacing wire 11 in double-layer plate 5 both sides.
Tie up outside the steel pipe 3 at last and the reinforcing bar of double-layer plate 5 both sides, comprise vertical muscle 8, the stirrup 9 in the steel tube concrete superposed column, interior vertical muscle 10, the lacing wire 11 of body of wall in the steel tube concrete superposed column, prop up template then, fluid concrete is finished constructing of internal division type laminated column frame-bilayer steel plate combined concrete shear wall.
More than be an exemplary embodiments of the present utility model, enforcement of the present utility model is not limited thereto.
