A Bailey Beam Hinge Bearing

Abstract

The invention discloses a bailey beam hinged support and belongs to the technical field of bridge engineering. The bailey beam hinged support comprises lug plates, stiffening plates, a bottom plate and lengthened bailey pins. The bottom plate is a rectangular plate. The lug plates are wipe-corner rectangular plates and are provided with pin holes matched with the lengthened bailey pins. The two lug plates are welded to the two ends of the bottom plate vertically and perpendicularly. In order to ensure the stability of the lug plates, the lug plate stiffening plates are arranged, are welded to the bottom plate and are located on the outer sides of the two lug plates; and lower chord female and male connectors of two bailey beams are located between the two lug plates and are aligned at the pin holes in the lug plates, and the lengthened bailey pins penetrate through the pin holes for fixation. The bailey beam hinged support is used, thus downward sliding force of an upper structure and automobile braking force can be effectively transmitted to a lower structure, the effect that the downward sliding force transmitted by the upper structure can be transmitted to the lower structure in time at any time is ensured by a lengthened hinge pin, the lug plates and the bottom plate, and the problems that a traditional wedge block cannot transmit horizontal force and a bailey beam can only be erected horizontally are solved. The adaptability is high, recycling is achieved, and assembly is convenient.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering and relates to the erection of temporary Bailey beam trestle bridges, in particular to a Bailey beam hinge support for large-slope trestle bridges. Background technique [0002] The bridge support is set between the superstructure of the bridge and the piers, and its function is to transfer various load reactions on the bridge span structure to the piers, while ensuring the required displacement and rotation of the bridge span structure. [0003] Traditional trestle bridges and construction platforms are erected horizontally. However, in some occasions, due to the limitation of the force site, the trestle has to be placed obliquely, so as to reduce the occupied area. The downward force along the slope generated by inclined placement is inevitable. If the existence of the downward force is ignored, it will cause great safety hazards to the safety of the structure.

However, in some occasions, due to the limitation of the force site, the trestle has to be placed obliquely, so as to reduce the occupied area

The downward force along the slope due to inclined placement is inevitable. If the existence of the downward force is ignored, it will cause great safety hazards to the safety of the structure.

[0004] The ability of the traditional wedge to solve the problem of slope is obviously insufficient: 1. Poor adaptability, different wedges need to be set according to different slopes; The Bailey Beam cannot be welded

At present, there is no simple and feasible method for erecting Bailey beams with large slopes in China.
