Abstract

The invention provides a spherical support with an additional anti-drawing function. The spherical support comprises an upper support plate, a sliding plate, a piston and a lower support plate, wherein the piston and the lower support plate are matched with each other; a concave spherical surface and a convex spherical surface are arranged at the two ends of the piston respectively, a second middle seat plate is placed in the concave spherical surface, and a first middle seat plate is placed on the convex spherical surface; the second middle seat plate is located between the piston and the lower support plate. The second middle seat plate and the first middle seat plate are spherical surfaces with the same arc direction. The problems existing in two existing technical schemes in the background technology are ingeniously solved, including the defects that the structural size of the first technical scheme is too large, and the second technical scheme is difficult to assemble, complex in structure and prone to loosening.

Description

technical field [0001] The invention relates to the technical field of bridge bearings, more specifically, to a spherical bearing with an additional pull-out resistance function. Background technique [0002] At present, in straddle-type monorail, cantilever beam and steel structure buildings, the supports used not only need to have the functions of bearing vertical force, horizontal force, horizontal displacement and rotation, but also need to withstand a certain pull-out force. In the prior art, there are two technical solutions for the anti-pullout spherical bearing: [0003] Technical solution 1: The upper seat plate, the piston, and the lower support plate of the support are provided with a pull-out structure, and the upper and lower parts of the support are connected through the structure of the support itself or an additional anti-draw plate to realize the pull-out resistance function. See search patents 1-7, the common feature of such technical solutions is: the ant...
