Novel suspended monorail pier and track beam connecting structure

Abstract

The invention discloses a novel suspended monorail pier and track beam connecting structure. The novel suspended monorail pier and track beam connecting structure comprises a hanging box arranged on apier and a corbel mounted on a track beam, wherein a support mounting base is arranged at the bottom of the hanging box; the corbel is mounted on the support mounting base through a support; the support comprises an upper support plate and a lower support plate; a sliding base is arranged between the upper support plate and the lower support plate; a longitudinal limiting device is further mounted on the support; a gap is formed between the longitudinal limiting device and the lower support plate; through the gap, the support can move longitudinally within the range of the gap; when the longitudinal displacement of the support exceeds the gap, the longitudinal limiting device can limit the support. The novel suspended monorail pier and track beam connecting structure solves the strict restriction of the specification on the displacement of the pier top of a suspended monorail pier, and can reduce the cross section of the pier body of the pier, so that the project cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of suspended monorails, in particular to a novel connection structure between suspended monorail bridge piers and track girders. Background technique [0002] The safe and effective connection between suspended monorail bridge piers and track girders is an important link in the design of suspended monorails. Generally speaking, the suspended monorail pier and the track girder can be connected by bolts, and the bolt connection has the advantages of simple structure and convenient installation. Such as figure 1 As shown, a reinforcing plate 2 is provided at the end of the track beam 1, and a pin hole 6 is provided on the reinforcing plate 2, and a hanging plate 4 is provided on the Y-shaped pier 3, and a pin hole 6 is also provided on the hanging plate 4, and through The pin 5 is connected with the reinforcing plate 2 . However, in actual use, the bolt-type connection gradually reveals various deficiencies....

AI Technical Summary

Problems solved by technology

However, in actual use, the bolt-type connection gradually reveals various deficiencies. First, the reinforcement plate 2 and the track beam 1 are connected by welds. , the force is uneven, local stress is large, and the fatigue problem is prominent; secondly, in view of the domestic steel structure processing level and the installation level of the construction team, it is necessary to carry out the deviation in the production and installation of the steel structure during construction. Remedy, while the adjustable range of the bolt connection is small and the adjustment is inconvenient

At the same time, the hanging plate 4 connected by the plug type generally has a thickness of more than 75mm, while the design of the current suspended monorail steel structure in China refers to TB10091-2017 "Code for the Design of Steel Structures of Railway Bridges", which stipulates the maximum thickness of the plate under various conditions It should not exceed 50mm. Obviously, when using the plug-in type, it is necessary to break through this specification, which will bring great difficulties to the actual design
