[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 described embodiments 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 creative work 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] Curtain wall spherical bearings, as the name implies, are bearings with a spherical structure. They are usually installed on the supporting structure of the curtain wall to bear external loads such as the curtain wall's deadweight, wind loads, and earthquakes, and allow the curtain wall to rotate in multiple directions within a certain range. According to the usage scenario and performance requirements, curtain wall spherical bearings can be divided into fixed bearings, unidirectional movable bearings, and multidirectional movable bearings.

[0031] 2. Working Principle

[0032] The working principle of the curtain wall spherical bearing is mainly based on the principle of ball-groove combination. The middle spherical steel plate of the bearing slides and moves in the lower bearing plate to meet the needs of the upper structure. Since the rotation center of the bearing may not coincide with the dynamic center of the upper structure, a sliding surface is formed between the upper bearing plate and the flat PTFE plate. Depending on the relative position of the rotation center of the superstructure and the bearing, the rotation direction of the spherical surface can be consistent with or opposite to the sliding direction of the plane. If the two rotation centers coincide, no sliding occurs on the plane.

[0033] 3. Features and advantages

[0034] Large 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 the embedded steel plates of the pier.

[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 rotation flexibility.

[0048] 5. Application Scenarios

[0049] Curtain wall spherical bearings are widely used in curtain wall systems such as 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 performance requirements.
