Embodiment Construction
[0025] The structure of the curved surface rotating support provided by the utility model will be further described in detail below in conjunction with the accompanying drawings.
[0026] Such as Image 6 Shown is a schematic structural view of the first spherical rotatable bearing provided by the present invention. The structure of the spherical rotatable bearing includes an upper bearing plate 1 that can be fixed to the bridge beam body through anchor bolts 6 and a lower bearing plate 5 that can be fixed to the pier through anchor bolts 6, wherein the top surface of the lower bearing plate is convex Spherical crown surface, the bottom surface of the upper support plate is a concave spherical surface corresponding to the convex spherical crown surface of the lower support plate; a spherical stainless steel slide plate 3 is arranged on the convex spherical crown surface of the lower support plate, and the upper support plate A spherical tetrafluoro slide plate 2 corresponding...

The invention belongs to the technical field of bridge engineering, and discloses a curved surface rotary support. The technical proposal of the curved surface rotary support comprises the following: the curved surface rotary support comprises an upper support plate and a lower support plate which are fixedly connected with a beam body and a pier respectively through connecting mechanisms; the top surface of the lower support plate is a convex curved surface, and the bottom surface of the upper support plate is a concave curved surface corresponding to the convex curved surface of the lower support plate; the convex curved surface of the lower support plate or the concave curved surface of the upper support plate is embedded with a tetrafluorated slide plate; and the rotation of the support is realized by the sliding between the tetrafluorated slide plate embedded in the curved surface of the upper support plate or lower support plate and the corresponding lower support plate or uppersupport plate. The technical proposal overcomes the defect of unreasonable structure in the prior curved surface rotary support.
Description
technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a curved surface rotating support with ultra-high bearing capacity. Background technique [0002] The bearing is the force transmission device between the superstructure and the substructure of the bridge. According to the introduction in "Bridge Engineering" (Edited by Fan Lichu, People's Communications Publishing House), the sixth chapter of the support of the beam bridge, its function is: ①Transfer the supporting reaction force of the upper structure (including the vertical force and horizontal force caused by dead load and live load) ② Ensure that the structure undergoes a certain deformation under the action of factors such as live load, temperature change, concrete shrinkage and creep, so that the actual stress of the upper and lower structures conforms to the static calculation diagram of the structure (such as figure 1 Shown is "Bridge Engineering"...
