A kind of novel both sides connect thin steel plate shear wall
Technical field
The utility model relates to a kind of steel plate shear force wall, and especially a kind of novel both sides connect thin steel plate shear wall.
Background technology
The steel plate shear force wall structure is a kind of novel anti side force structural system that grows up the seventies in 20th century.For realizing the fire retardant anticorrosion of steel plate shear force wall, usually can be at its both sides external wrapping concrete.Thereby external wrapping concrete also can prevent or slow down outside the plane of steel plate wall bending deformation simultaneously and improve its anti-seismic performance and especially be out of shape and energy dissipation capacity.
The common structure method of existing steel plate wall external wrapping concrete is: offer the Long Circle bolt hole and place plastic bushing in the hole at precast concrete plank, simultaneously also offer bolt hole in the steel plate wall relevant position, by pre-stressed bolt concrete slab is fixed on main steel plate wall both sides then.For the bolt of main steel plate wall both sides concrete slab can be loaded onto smoothly, need offer the Long Circle bolt hole at main steel plate or concrete slab, and place within it in order to prevent that concrete from being squeezed broken sleeve pipe, therefore textural cumbersome.
The utility model content
The utility model provides a kind of simple in structure, easily manufactured novel both sides to connect thin steel plate shear wall.
A kind of novel both sides of realizing the utility model purpose connect thin steel plate shear wall, comprise thin steel plate shear wall, and described thin steel plate shear wall top is provided with upper ledge and sets a roof beam in place, and the below is provided with lower frame and sets a roof beam in place; Two sides of described thin steel plate shear wall are provided with and are respectively equipped with edge stiffening rib and intermediate stiffener, be welded with a plurality of buckle bar dowels on the described edge stiffening rib, a plurality of parallel vertical long reinforcing bars and horizontal long reinforcing bar are fixedly arranged on the described buckle bar dowel, described vertical long reinforcing bar and horizontal long reinforcing bar form two reinforced mesh in the both sides of thin steel plate shear wall, and fluid concrete forms the external wrapping concrete plate on described reinforced mesh.
Described horizontal long reinforcing bar passes the through hole of intermediate stiffener, and is welded on the through-hole wall.
Be fixed together by the upper ledge junction plate of setting a roof beam in place between described thin steel plate shear wall and upper ledge are set a roof beam in place, described thin steel plate shear wall and lower frame are set a roof beam in place and are welded together.
Described edge stiffening rib comprises transverse edge stiffening rib and longitudinal edge stiffening rib, and described longitudinal edge stiffening rib top is provided with two capping plates, and described capping plate is positioned at the set a roof beam in place two ends of junction plate of upper ledge.
The top that is positioned at the transverse edge stiffening rib of thin steel plate shear wall top is provided with two and is used for two clamping plate that the clamping upper ledge is set a roof beam in place.
Offer bolt hole on the described clamping plate, and be connected by high-strength friction-type bolt and the upper ledge junction plate of setting a roof beam in place.
Described clamping plate lateral surface center line adds web along its length, makes these clamping plate T-shaped.
The cross section of described edge stiffening rib and intermediate stiffener is flute profile, worker's shape or rectangle.
The beneficial effect that a kind of novel both sides of the present utility model connect thin steel plate shear wall is as follows:
A kind of novel both sides of the present utility model connect thin steel plate shear wall, use stiffening rib to form cage of reinforcement and then realization external wrapping concrete, thereby have avoided adopting pre-stressed bolt to fix many troubles that the both sides concrete slab brings, and are easily manufactured; Simultaneously, when the measure of taking concrete and longitudinal edge shaped steel to put more energy into to leave certain interval makes concrete slab outer distortion has effect of contraction to the face of steel plate wall, and limited to the raising effect of rigidity in its face, to guarantee the pure property of external wrapping concrete steel plate shear force wall component performance.
Description of drawings
Fig. 1 is the structural representation that a kind of novel both sides of the present utility model connect thin steel plate shear wall.
The specific embodiment
As shown in Figure 1, a kind of novel both sides of the present utility model connect thin steel plate shear wall, comprise thin steel plate shear wall 1, and described thin steel plate shear wall 1 top is provided with upper ledge and sets a roof beam in place 8, and the below is provided with lower frame and sets a roof beam in place 9; Two sides of described thin steel plate shear wall 1 are provided with and are respectively equipped with edge stiffening rib 6 and intermediate stiffener 7, be welded with a plurality of buckle bar dowels 3 on the described edge stiffening rib 6, a plurality of parallel vertical long reinforcing bars 5 and horizontal long reinforcing bar 4 are fixedly arranged on the described buckle bar dowel 3, described vertical long reinforcing bar 5 and horizontal long reinforcing bar 4 form two reinforced mesh in the both sides of thin steel plate shear wall 1, and fluid concrete forms external wrapping concrete plate 14 on described reinforced mesh.
Described horizontal long reinforcing bar 4 passes the through hole of intermediate stiffener 7, and is welded on the through-hole wall.
Described thin steel plate shear wall 1 and upper ledge are set a roof beam in place between 8 and to be fixed together by the upper ledge junction plate 10 of setting a roof beam in place, and described thin steel plate shear wall 1 and lower frame are set a roof beam in place and 9 welded together.
Described edge stiffening rib 6 comprises transverse edge stiffening rib and longitudinal edge stiffening rib, and described longitudinal edge stiffening rib top is provided with two capping plates 13, and described capping plate 13 is positioned at the set a roof beam in place two ends of junction plate 10 of upper ledge.
The top that is positioned at the transverse edge stiffening rib of thin steel plate shear wall 1 top is provided with two and is used for two clamping plate that the clamping upper ledge is set a roof beam in place.
Offer bolt hole on the described clamping plate, and be connected by high-strength friction-type bolt and the upper ledge junction plate 10 of setting a roof beam in place.
Described clamping plate lateral surface center line adds web along its length, makes these clamping plate T-shaped.
The cross section of described edge stiffening rib 6 and intermediate stiffener 7 is flute profile, worker's shape or rectangle.
The advantage that a kind of novel both sides of the present utility model connect thin steel plate shear wall is as follows:
A kind of novel both sides of the present utility model connect thin steel plate shear wall, use stiffening rib to form cage of reinforcement and then realization external wrapping concrete, thereby have avoided adopting pre-stressed bolt to fix many troubles that the both sides concrete slab brings, and are easily manufactured; Simultaneously, when the measure of taking concrete and longitudinal edge shaped steel to put more energy into to leave certain interval makes concrete slab outer distortion has effect of contraction to the face of steel plate wall, and limited to the raising effect of rigidity in its face, to guarantee the pure property of external wrapping concrete steel plate shear force wall component performance.
Embodiment recited above is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
