Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a core tube steel plate shear wall structure and a construction method thereof. Background Art

[0002] With the rapid development of domestic steel structure design, higher requirements have been formed for the span, cantilever, and shape design of steel structures. The spatial scale of building structures has gradually increased, and the design style has become more advanced. High-rise and super-high-rise or large-span and large-cantilever structures are being used more and more, and the height, span and cantilever length have gradually increased.

[0003] In high-rise, super-high-rise, or long-span buildings, steel plate shear walls are a cylindrical structural design that effectively resists horizontal loads. Shear walls within the core divide the concrete core into two sections. If large horizontal supports are placed on the outside of the core, the embedded components of the horizontal supports will have difficulty crossing the steel plate shear walls within the core.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] In order to overcome the defects of the existing technology, a core tube steel plate shear wall structure and a construction method thereof are now provided to solve the problem that when horizontal supports are arranged on the outside of the core tube of a super high-rise building, the embedded parts of the horizontal supports are difficult to cross the steel plate shear wall inside the core tube.

[0006] To achieve the above object, a core tube steel plate shear wall structure is provided, comprising:

[0007] A steel frame, comprising a core steel plate, a plurality of tension plates, and steel claws, wherein the core steel plate has a front face and a back face, the plurality of tension plates are arranged at intervals in the horizontal direction, the tension plates are arranged in the vertical direction, the tension plates have opposing first and second ends, the first ends of the plurality of tension plates are connected to the front face, and a connecting plate is connected between the plurality of tension plates, and the steel claws include a plurality of anchor steel bars, the anchor steel bars are detachably mounted on the back face, and the positions of the anchor steel bars correspond to the positions of the tension plates;

[0008] Concrete, covering the steel frame;

[0009] a panel embedded in the surface of the concrete and connected to the second ends of the plurality of tension plates;

[0010] A support plate for connecting horizontal supports is connected to the outer side of the panel, and a diagonal support plate is connected between the bottom of the support plate and the panel.

[0011] Furthermore, the upper and lower parts of each tension plate are correspondingly provided with the anchor steel bars.

[0012] Furthermore, a connecting sleeve is fixedly provided on the back side, one end of the anchoring steel bar is inserted into the connecting sleeve, and the other end of the anchoring steel bar is buried in the concrete.

[0013] Furthermore, the connecting sleeve is formed with an internal thread, one end of the anchoring steel bar is formed with an external thread, and one end of the anchoring steel bar is screwed into the connecting sleeve.

[0014] Furthermore, the support plate and the connecting plate are arranged coplanarly.

[0015] Furthermore, the support plate is arranged at a middle position of the panel.

[0016] The present invention provides a construction method of a core tube steel plate shear wall structure, comprising the following steps:

[0017] Installing steel frames on the frame structure of the core tube so that the back side of the core steel plate of the steel frames faces the inner side of the core tube;

[0018] Concrete is poured on the front and back of the core steel plate respectively, so that the concrete covers the steel frame and the panel is embedded in the surface of the concrete;

[0019] hoisting a horizontal support to the outside of the panel;

[0020] The horizontal supports are connected to the support plate.

[0021] The beneficial effect of the present invention is that the core tube steel plate shear wall structure of the present invention indirectly realizes the embedded parts spanning both sides of the shear wall steel plate and transmitting force through the node structure, and at the same time facilitates the connection construction between the horizontal support outside the core tube and the core tube and the steel plate shear wall. On the one hand, there is no need to open large embedded holes on the steel plate shear wall to weaken the shear wall steel plate, thereby maintaining the integrity of the steel plate wall. On the other hand, this node structure is used to indirectly realize the embedded parts spanning the shear wall steel plate and transmitting force, which facilitates the transmission of the horizontal support force to both sides of the steel plate shear wall, thereby avoiding the problem of uneven force on one side of the steel plate shear wall.

[0035] The support plate 4 is connected to the outside of the panel 3, and a diagonal brace plate 41 is connected between the bottom of the support plate 4 and the panel 3. The support plate 4 is used to connect the horizontal support 5 of the frame structure outside the core tube.

[0036] The core tube steel plate shear wall structure of the present invention indirectly realizes the embedded parts spanning both sides of the shear wall steel plate and transmitting force through the node structure, and at the same time facilitates the connection construction between the horizontal support outside the core tube and the core tube and the steel plate shear wall. On the one hand, there is no need to open large embedded holes on the steel plate shear wall to weaken the shear wall steel plate, thereby maintaining the integrity of the steel plate wall. On the other hand, this node structure is used to indirectly realize the embedded parts spanning the shear wall steel plate and transmitting force, which facilitates the transmission of the horizontal support force to both sides of the steel plate shear wall, avoiding the problem of uneven force on one side of the steel plate shear wall.

[0037] The core tube steel plate shear wall structure of the present invention has a support plate connected to the horizontal support by bolts, which makes it more convenient to connect the horizontal support outside the core tube and the embedded parts, is simple to construct, and has good force transmission.
