[0002] A cantilever beam refers to a beam with one end fixed on a support and the other end extending out of the support; a sliding bearing refers to a structure with a sliding lower part of the bearing; sliding bearings are usually used in buildings or bridge structures that need to withstand horizontal loads and displacements to eliminate the influence of horizontal and vertical forces caused by factors such as temperature, settlement, and earthquakes, and to avoid damage to the superstructure.
[0003] In the related art, the cantilever beam is set on the outer wall with the help of sliding supports, and a deformation joint is left between the beam and the outer wall. However, since one end of the cantilever beam extends out of the support, the existing support form is often unable to bear the full weight of the cantilever beam. Under special climatic or geological conditions, such as strong winds, earthquakes, etc., the beam is prone to vibrate. When the cantilever beam is subjected to horizontal or vertical external forces, the beam is easy to detach from the support when sliding, affecting the safety of the entire building. Summary of the invention
[0004] In view of this, the present invention provides a sliding support node at the cantilever beam of the outer wall to solve the problem that the existing sliding support arranged at the cantilever beam of the outer wall is difficult to bear the full weight of the cantilever beam, the beam body is prone to vibrate under special climatic or geological conditions, and the cantilever beam is easy to detach from the support when subjected to external force, affecting the safety of the entire building.
[0005] The present invention provides a sliding support node at a cantilever beam of an exterior wall, which is arranged on the exterior wall, and the sliding support node at the cantilever beam of the exterior wall comprises: a cantilever beam, which is spaced apart from the exterior wall, and the cantilever beam has a first beam and a second beam connected to each other; a corbel, which is formed by protruding from a part of the wall of the exterior wall, and the corbel is located relatively below the second beam; a sliding component, which is arranged between the corbel and the cantilever beam and is suitable for making the cantilever beam slidably arranged at the corbel; the sliding component comprises: a first plate, which is fixed to the corbel; a lubricating plate, which is placed on the plate surface of the first plate; a second plate, which is fixed to the second beam; wherein the second plate is pressed against the lubricating plate, and the lubricating plate can slide relative to the first plate and the second plate; wherein at least two side plates are provided at the first plate, and at least two of the side plates are respectively located on opposite sides of the second beam along the first direction.
[0006] In an optional embodiment, the first plate is fixed to the corbel by means of a first U-shaped rib; wherein the side of the first U-shaped rib is fixed to the plate surface of the first plate, and the rib body of the first U-shaped rib is embedded and fixed inside the corbel.
[0007] In an optional embodiment, the second plate is fixed to the second beam by means of a second U-shaped rib; wherein the side of the second U-shaped rib is fixed to the plate surface of the second plate, and the rib body of the second U-shaped rib is embedded and fixed inside the second beam.
[0008] In an optional implementation, the second beam is extended along a second direction.
[0009] In an optional embodiment, the corbel has the same length as the first plate in the second direction and is aligned with the first plate.
[0010] In an optional implementation, the width of the first plate in the first direction is L1, and the width of the second beam in the first direction is L2, wherein: L1>L2.
[0011] In an optional implementation, the absolute value of the difference between the width L1 of the first plate in the first direction and the width L2 of the second beam in the first direction is L0, where: 100 mm≤L0≤200 mm.

[0015] Beneficial effects: For the cantilever structure at the deformation joint of the outer wall, a sliding bearing form of corbel support is adopted. Compared with the existing bearing form, the corbel support is directly arranged at the outer wall to achieve high supporting performance, which can better bear the entire weight of the cantilever beam and ensure the stability of the supporting point of the cantilever beam. Under special climatic or geological conditions, since the sliding bearing is arranged on the corbel support, the cantilever structure is stable as a whole and is not prone to vibration; and side panels are added at the first plate, which can effectively prevent the cantilever beam from detaching from the support when subjected to external force, thereby ensuring the safety of the building.

[0017] Beneficial effects: For the cantilever structure at the deformation joint of the exterior wall, a sliding support form supported by a corbel is adopted. Compared with the existing support form, the sliding form is flexible. The lubrication plate is clamped between the first plate and the second plate and can slide in the horizontal direction relative to the first plate and the second plate, ensuring that the cantilever beam can be slidably set on the corbel of the exterior wall, effectively alleviating the deformation generated between the two structures. The polytetrafluoroethylene plate is used as a lubricating material, which has the characteristics of self-lubrication and maintenance-free, and has an extremely low friction coefficient, reducing the subsequent maintenance cost and workload.
[0018] Beneficial effect: For the cantilever structure at the deformation joint of the exterior wall, a sliding support with corbel support is adopted. Compared with the existing support form, it has strong adaptability, simple structure, large bearing capacity, strong adaptability and long service life, and can be widely used in various buildings that require cantilever structures.
