Example Embodiment

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] An inverted steel truss girder spherical bearing, such as figure 1 As shown, including the upper seat plate 1, the spherical crown lining plate 4 and the lower seat plate 6;

[0026] The upper surface of the upper seat plate 1 is a plane solidly connected with the steel truss girder bridge, and the upper seat plate 1 is connected with the steel truss girder by bolts; the lower surface of the upper seat plate 1 is a concave sphe...

Abstract

The invention discloses an inverted steel truss girder spherical support which comprises an upper seat plate, a spherical crown lining plate and a lower seat plate. The lower surface of the upper seatplate is a concave spherical surface, an upper seat plate limiting block is arranged on the end side of the lower surface of the upper seat plate, and a curved-surface sliding plate is embedded and fixed on the lower surface of the upper seat plate through a first embedding groove; the upper surface of the spherical crown lining plate is a convex spherical surface, curved-surface stainless steelis fixed on the upper surface of the spherical crown lining plate, and the other surface of the curved-surface stainless steel abuts against the curved-surface sliding plate and a sealing ring; lowerseat plate flange is arranged on the outer wall of the peripheral side of the lower seat plate, the outer wall of the peripheral side of the lower seat plate flange abuts against the inner wall of theperipheral side of the upper seat plate basin ring, and therefore the upper seat plate basin is wrapped with the lower seat plate flange. According to the invention, the deviation of the support to the bearing counter-force point of the steel truss girder caused by the rotation or horizontal sliding of the support is avoided, and the stress reliability of the steel truss girder is ensured; the structure that the upper base plate wraps the lower base plate is adopted, the waterproof and dustproof effects are achieved, and the problem that the support is rusted due to the fact that condensate water or rainwater cannot be drained is particularly avoided.

Description

technical field [0001] The invention belongs to the technical field of bridge accessories, and in particular relates to an inverted steel truss girder spherical bearing. Background technique [0002] With the rapid development of bridge projects such as passenger-dedicated railways, high-speed railways, expressways and urban overpasses in China, spherical bearings, as a new type of bridge bearings, are widely used in It has gradually been widely used in large-scale applications in railway bridges and highway bridges. Steel truss bridge is a commonly used bridge type of railway bridge. The beam body load-carrying structure is formed by truss. Bridge piers. Since the beam load of the steel truss girder bridge is transmitted to the pier through the nodes, it is necessary to ensure that the beam nodes always coincide with the action line of the lower support reaction force when the bridge is working. When the corner is turned, the steel truss girder force transmission node an...
