Description
Technical field
The present invention relates to concrete construction technical field, specifically a kind of steel reinforced concrete shearing force of built-in horizontal diagonal brace
Wall.
Background technology
With the continuous quickening of the fast-developing and urbanization process of Chinese national economy, Development of High-rise Buildings is rapid, and
Shear wall is most basic vertical structure component in high building structure, is primarily subjected to the effect of horizontal force, is effectively anti-
Side force component.But building height constantly rises, traditional shear wall has been difficult to meet building function requirement, steel reinforced concrete shear walls
Possess good bearing capacity and ductility, with very big development potentiality, but during geological process, steel reinforced concrete shearing
Easily there is crack in wall member surface concrete, and crack continues to develop in seismic process, damages aggravation so that anti-seismic performance is significantly
Degree declines.Prestressing force can effectively limit concrete structure crack generation with development and can improve unload after structure it is extensive
Multiple power performance, domestic and foreign scholars have carried out substantial amounts of research, but prestressing force in steel reinforced concrete shear walls field to prestressing force
Application also there is problem in terms of structure type, construction technology.
The content of the invention
For above technological deficiency, it is an object of the invention to provide a kind of steel reinforced concrete shearing force of built-in horizontal diagonal brace
Wall, the present invention combines prestressing technique and reinforced concrete composite structure technology, proposes a kind of limitation crack progressing simultaneously
Improve anti-seismic performance, structure optimization, the steel reinforced concrete shearing force of new built-in horizontal diagonal brace simple to operate of shearing wall member
Wall.
Technical scheme is as follows：
A kind of reinforced concrete shear wall of built-in horizontal diagonal brace, including concrete walls branch, are built in the steel truss of concrete walls branch
Frame and stress distribution diagonal brace, it is characterised in that：The stress distribution diagonal brace includes horizontal steel sleeve, flexible pipe and prestress steel
Muscle, the steel truss both sides be reserved with just to through hole, the horizontal steel sleeve is respectively penetrated in the through hole, just to set
Described horizontal steel sleeve between by set the flexible pipe be interconnected, in the described horizontal steel sleeve and inside hose of insertion
Run through into the same deformed bar, described deformed bar one end is anchored with pad nut, the other end extends to described mixed
The after-applied prestressing force in solidifying cob wall branch outside is simultaneously anchored with pad nut.
Steel sleeve middle part is attached using flexible pipe, can make the more effective prestressing force effects of prestressing force of institute's tensioning in type
On the concrete of steel concrete shear wall, prestressed utilization rate is lifted.
Specifically, be provided with outside the flexible pipe making the reinforcing bar of its holding level.
Specifically, the concrete walls branch is internally provided with distribution bar.
Specifically, the through hole carries out reinforcement solutions.
By reinforcement solutions, it is ensured that the integrality and extension duct service life in duct, enhancing structure anti-seismic performance.
Reinforcement solutions make it have current designs specification and the security required by owner, durability and applicability.
Specifically, the horizontal steel sleeve is coated with waterproof gasket cement with flexible pipe junction.
Used as preferred, the deformed bar pricks screw-thread steel for essence.
Used as preferred, the flexible pipe is wired hose.
Used as preferred, the steel truss is welded by channel-section steel, band steel and angle steel.
Specifically, prestressing force uses posttension soap-free emulsion polymeization method, unidirectional single tension.
Using posttension soap-free emulsion polymeization method, duct is without grouting, short construction period, easy construction；Good economy performance, building cover structure body
System is slim and graceful, and span is big；Loss of prestress is relatively small.
The beneficial effect of the invention is：
（1）The cracking load of steel reinforced concrete shear walls is effectively improved, with the generation of limitation crack and the remarkable result of development, is given
Comfort on people's sense organ.
（2）Due to limiting the generation and development in crack, damage of the concrete during geological process is reduced so that shaped steel
Concrete shear wall member energy dissipation capacity is increased substantially, enhancing structure anti-seismic performance.
（3）Sleeve pipe middle part is attached using wired hose, can make the more effective prestressing force of prestressing force of institute's tensioning
For the concrete of steel reinforced concrete shear walls, prestressed utilization rate is lifted.
（4）Prestressed tensioning just can be realized using pad and the simple standard component of nut, construction is simple, unidirectionally once opens
Draw, be not in the milk inside duct, convenient following shearing wall member prestressing force is overhauled, changes, exits work.
