Fabricated connecting structure used for suspension type monorail traffic track beam and construction method

Abstract

The invention relates to the technical field of track traffic, and discloses a fabricated connecting structure used for a suspension type monorail traffic track beam and a construction method. The fabricated connecting structure specifically comprises a bottom connecting mechanism, a side connecting mechanism and a supporting mechanism. The side connecting mechanism comprises side connecting plates which are arranged in a left-right symmetry mode. After sections of connecting ends of a front track beam and a rear track beam adjacent to the front track beam are aligned, the side connecting plates are attached to and mounted on the connecting position of webs on the two sides, the webs at the connecting ends of the front and rear track beams are provided with web mounting holes, the side connecting plates are provided with side connecting plate mounting holes corresponding to the web mounting holes, the side connecting plates and the corresponding webs can be connected through bolts, the inner surfaces of the positions, at the connecting end of the front track beam, of the webs and the inner surfaces of the positions, at the connecting end of the rear track beam, of the webs are located in the same plane, and flat connection of the side portions of the front and rear track beams is achieved. The fabricated connecting structure is simple in structure and fast and convenient to mount, the structural strength and flatness of the connecting position of the adjacent track beams are guaranteed, and comfort and safety of rail transport are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an assembled connection structure and a construction method for a suspended monorail rail beam. Background technique [0002] The suspended monorail transportation system is the sky rail train. The track is above the train and supported in the air by steel or cement columns. Since the ground traffic is moved to the air, urban traffic problems can be alleviated without expanding the city's existing road facilities. And because it only moves the track into the air, instead of lifting the entire road into the air like elevated light rail or riding monorail, it overcomes the disadvantages of other rail transit systems and has many outstanding features and advantages in terms of construction and operation. . [0003] Suspended track beams usually have two cross-section forms: I-shaped and bottom-opened box-shaped. When the cross-section is box-shaped with bottom open, the web o...

Problems solved by technology

[0003] Suspended track beams usually have two cross-section forms: I-shaped and bottom-opened box-shaped. When the cross-section is box-shaped with bottom open, the web of the track beam sometimes contacts with the guide wheels on the side, especially in curved roads. At this time, due to the effect of centrifugal force, the contact between the guide wheel and the web is more closely, which requires that the strength of the joint between two adjacent track beam webs is high enough and the flatness is good enough to ensure that the guide wheel passes through the joint smoothly and prevents the trolley from If the lower flange of the track girder is in contact with the traveling wheels, the connection between the lower flanges of two adjacent track girders is required to have high joint strength and good flatness, so that there is no obvious butt joint interface, so as to ensure that the traveling wheels pass through the joint. There is no bumping or jumping up and down; since the track beams are erected in the air at a certain distance from the ground, they are all supported by pillars, but the existing support structure design is often too complicated, and the installation and adjustment are difficult, and the construction and installation efficiency is low
