Description

Technical Field

[0001] This utility model relates to the field of vibration-damping building construction and technology, specifically to a cantilever wall structure with hidden beams and columns. Background Technology

[0002] In high-intensity seismic zones and earthquake monitoring areas, medical facilities, schools, and other buildings should employ appropriate seismic isolation and damping technologies to ensure normal operation during the occurrence of the region's design earthquake. Viscous dampers (VFDs) can provide additional damping to buildings, improving their energy dissipation capacity, and are widely used in structural design. Among these, cantilever wall installations are favored by designers due to their minimal impact on building functionality. The reliability of the connection between the cantilever wall and the VFD is a crucial aspect of the design process. Currently, the main connection method used in building construction is the use of pre-embedded plates with anchor bars. This method has the following shortcomings: Under strong earthquakes, this type of connection is prone to severe damage such as the anchor bars being completely pulled out of the concrete component, the pre-embedded plate separating from the anchor bars, and the anchor bars shearing, resulting in the complete loss of energy dissipation and damping function of the damping component, and insufficient safety of the connection node; Under earthquakes, this node is subjected to complex stresses, and the pre-embedded plate in the concrete component is under combined bending and shear stress, requiring a large number of pre-embedded anchor bars, which are prone to conflict with the reinforcement of reinforced concrete beams and columns; When the number of anchor bars is large, the construction is difficult, the quality of concrete forming is difficult to guarantee, and the performance of the component is difficult to achieve the design expectations. Utility Model Content

[0003] The purpose of this utility model is to provide a cantilever wall structure with hidden beams and columns. This structure can effectively improve the structural stability at the connection points, improve the safety of the overall building structure, ensure the reliability of the viscous damper, and facilitate maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cantilever wall structure with concealed beams and columns includes two vertically spaced cantilever walls and a viscous damper assembly installed between the two cantilever walls. Concealed beams and columns are provided within the cantilever walls, and the ends of the concealed columns are fixedly connected to the frame beams. Foam filling layers are provided on both sides of the viscous damper assembly and between the two cantilever walls. An access door is provided in front of the viscous damper assembly and between the two foam filling layers.

[0006] Preferably, two hidden columns are fixedly installed at both ends of the hidden beam, and the hidden beam and the hidden columns are connected to form an overall U-shape.

[0007] Preferably, an infill wall is provided on the outside of the cantilever wall, and both the upper and lower ends of the infill wall are connected to the frame beam.

[0008] Preferably, a galvanized steel wire mesh is wrapped around the outside of the foam filling layer.

[0009] Preferably, the viscous damper assembly includes a viscous damper, hinged supports installed at both ends of the viscous damper, and an embedded part fixedly installed at the bottom of the hinged supports, one end of the embedded part being fixedly connected inside the hidden beam.

[0010] Preferably, the thickness of the infill wall is 200mm.

[0011] In this invention, by concealing beams and columns within the cantilever wall, the overall structural strength is increased without affecting wall construction. Simultaneously, the embedded parts of the viscous damper assembly are fixedly connected to the reinforcing steel structure of the concealed beams, and the reinforcing steel structure of the concealed columns is connected to the frame beams, forming a stable whole. Under severe earthquake conditions, this effectively prevents the embedded parts from being pulled out or sheared from the concrete of the cantilever wall, improving the safety of the connection points. An access door is provided between the two cantilever walls for inspecting and maintaining the viscous damper, improving the convenience of maintenance operations. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1 to 4The cantilever wall structure shown includes two vertically spaced cantilever walls 1. Hidden beams 2 and hidden columns 3 are installed within the cantilever walls 1. The ends of the hidden columns 3 are fixedly connected to the frame beams 4. In this embodiment, two hidden columns 3 are fixedly installed at both ends of the hidden beams 2, forming a U-shape when connected. The hidden beams 2 and hidden columns 3 are made of the same set of steel bars bent into a U-shape, integrally formed, resulting in good structural stability. The fixed connection of the ends of the steel bars of the two hidden columns 3 to the steel bars of the frame beams 4 increases the structural strength of the cantilever wall 1. Simultaneously, the hidden beams 2 serve as a solid foundation for the connection of the viscous damper assembly 5, ensuring seismic resistance.

[0019] An infill wall 6 is installed on the outer side of the cantilever wall 1. The upper and lower ends of the infill wall 6 are connected to the frame beam 4, and the sides of the infill wall 6 are connected to the frame columns. In this embodiment, the thickness of the infill wall 6 is 200mm, and an external decorative panel is installed on the outer side of the infill wall 6 to enhance the aesthetics of the overall structure.

[0020] A viscous damper assembly 5 is installed between the two cantilever walls. The viscous damper assembly 5 includes a viscous damper 50, hinged supports 51 hinged at both ends of the viscous damper 50, and an embedded part 52 fixedly installed at the bottom of the hinged supports 51. One end of the embedded part 52 is fixedly connected to the concealed beam 2 and / or the concealed column 3. Furthermore, to increase the stability of the connection, transverse reinforcement can be added between the embedded part 52 and the steel reinforcement structure of the concealed beam 2 to improve the connection strength.

[0021] Foam filling layers 7 are installed on both sides of the viscous damper assembly 5 and between the two cantilever walls 1. The foam filling layers 7 can also be replaced with fire-resistant flexible materials. Galvanized steel wire mesh is wrapped around the outside of the foam filling layers 7 to improve structural strength. An inspection door 8 is installed on the front side of the viscous damper assembly 5 and between the two foam filling layers 7. The inspection door 8 is normally locked. When maintenance of the viscous damper assembly 5 is required, the inspection door 8 can be opened for convenient operation. The inspection door 8 includes a door frame fixedly installed on the cantilever wall 1 and two door leaves hinged to both sides of the door frame.

[0022] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
