Seven Palm Spherical bearings

Home Projects Seven Palm Spherical bearings

Seven Palm Spherical bearings

Spherical steel bearings offered by pretread.com consists of a  top plate, convex middle plate concave base plate , where convex middle plate and two PTFE plates of different composition where concave spherical in the base plate, and the PTFE plate between them. Beam rotation through spherical surfaces and PTFE plate sliding; stainless steel plate on  top plate and another PTFE plates on  intermediate steel plate perform the second sliding surface, realized beam stretching displacement produced by temperature factors. Spherical bearing transfers force reliably and rotates smoothly. Spherical bearings can be designed for great bearing capacity, large displacement, and it has following advantages Spherical bearing transfers force through spherical surface, so no contraction of force will occur, and reacting force on concrete pier will be relatively even, requiring  less turning moment, related to  radius of  spherical face but not subject to  turning angle of  bearing, makes it suitable for large turning angles, even may be 0.05rad or more. Turning of spherical bearing is consistent in all directions makes it suitable for wide and curve bridges.
 
 
Advantage of spherical bearings is its capability to accommodate higher rotational values and it is proven in the following Project Seven Palm is a multi-building complex in Palm West Beach, Palm Jumeirah, Dubai, being developed by Al Memzar Investments Co is  situated opposite Nakheel Mall and next to Dukes Dubai Hotel on the trunk of Palm Jumeirah. Construction began in September 2018 and completed in  Q3 2021.
 
The development comprises two individual buildings: NH Dubai The Palm and Seven Palm Tower 2. These two towers of Seven Palm each have 14 storeys and building complex been launched "The Bridge Collection" with the description: "a collection of the most unique apartments and penthouses nestled in the largest sky bridge in the region." Expansion end of  the long multi-storeyed  sky bridge connection to next building with  large spherical bearings designed an manufactured by pretread.com POLYMET .The architect of the Project is Conin Incorporated Consultants, and Airolink Building Contracting LLC  the main contractor.
