[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Curtain wall spherical bearing is a type of bearing widely used in curtain wall structures. It combines the advantages of spherical bearings and is particularly suitable for curtain wall systems that need to withstand large loads and have multi-directional rotation performance requirements.

[0029] 1. Definition and Classification

[0030] As the name suggests, a curtain wall spherical bearing is a spherical structure. It is typically installed on the curtain wall's supporting structure to withstand external loads such as the curtain wall's own weight, wind loads, and earthquakes, while allowing the curtain wall to rotate in multiple directions within a certain range. Depending on the application scenario and performance requirements, curtain wall spherical bearings can be divided into various types, including fixed bearings, unidirectional movable bearings, and multidirectional movable bearings.

[0031] 2. Working Principle

[0032] The operating principle of curtain wall spherical bearings is primarily based on a ball-and-groove combination. The bearing's central spherical steel plate slides within the lower bearing plate to meet the needs of the superstructure. Because the bearing's rotational center may not coincide with the superstructure's dynamic center, a sliding surface is formed between the upper bearing plate and the flat PTFE plate. Depending on the relative positions of the superstructure and bearing's rotational centers, the direction of rotation of the spherical surface can be aligned with or opposite to the direction of sliding on the flat surface. If the two rotational centers coincide, no sliding occurs on the flat surface.

[0033] 3. Features and advantages

[0034] Large load-bearing capacity: Curtain wall spherical bearings can withstand large loads and are suitable for large curtain wall systems.

[0035] Flexible rotation: It has multi-directional rotation performance and can adapt to the deformation requirements of the curtain wall in different directions.

[0036] Strong displacement adaptability: Through the sliding displacement of the spherical steel plate, it can meet the displacement requirements of the curtain wall in horizontal, vertical and other directions.

[0037] Good durability: Since rubber is no longer used to bear pressure, there is no adverse effect such as rubber hardening or aging, so it is particularly suitable for low temperature areas.

[0038] 4. Installation and Maintenance

[0039] Installation steps:

[0040] Pier pretreatment: including surface roughening, reserved hole processing, determination of the center line of the bearing design position, etc.

[0041] Grouting: Carry out gravity grouting and remove the formwork after the mortar hardens.

[0042] Support installation: Hoist the support to the predetermined position, adjust the level and elevation, and ensure that the center line of the support completely coincides with the design axis of the pier support.

[0043] Connection and fixation: Weld or bolt the upper and lower support plates to the beam body and pier embedded steel plates.

[0044] Maintenance requirements:

[0045] Regularly check the appearance of the support for any damage and replace damaged parts in a timely manner.

[0046] Remove debris and dust around the support and keep the support surface clean.

[0047] The bearings are lubricated to reduce friction and improve rotational flexibility.

[0048] 5. Application Scenarios

[0049] Curtain wall spherical bearings are widely used in curtain wall systems for high-rise buildings, large public buildings, bridges, etc. Curtain wall spherical bearings play an irreplaceable role, especially in curtain wall systems that need to withstand large loads and have multi-directional rotation requirements.

[0050] In summary, curtain wall spherical bearings offer a wide range of advantages, including high load-bearing capacity, flexible rotation, and strong displacement adaptability. In curtain wall systems, they can effectively withstand external loads and allow the curtain wall to rotate in multiple directions within a certain range, thereby ensuring the stability and safety of the curtain wall system.
