Problems solved by technology

[0003] The installation method of the pre-embedded channel in the traditional concrete structure is as follows: 1) The pre-embedded channel is directly welded to the structural steel bar at the design position, so that the pre-embedded channel is close to the steel formwork, but this connection method is difficult for the maglev track beam The construction plan is not feasible; 2) Another way is to directly fix the embedded channel on the wooden formwork with iron nails, and use iron nails to nail the embedded channel in reverse, but this fixing method is only applicable to external The mold is a wooden mold, which has great limitations

Embodiment 1

[0035] In this embodiment, the contact rail channel of the magnetic levitation track beam is installed on the track beam of the straight section, such as Figure 1 to Figure 4 As shown, the track beam contact rail channel positioning mold used in this construction method includes a base plate 1 with a flat structure, and two limiting plates 2 arranged in parallel to each other are arranged on the base plate 1. The upper end of the plate 2 is provided with two positioning grooves 201 matching the width of the channel 3, and the distance between the two positioning grooves 201 on the same limiting plate 2 is the same as the preset position of the two channels 3. The distance is adapted, and a retainer 5 for fixing to the ends of the two channels 3 is also included, so that the channel group composed of the two channels 3 can still be kept parallel to each other after being removed from the limiting plate 2 .

[0036] In this embodiment, the two limiting plates 2 are vertically a...

Embodiment 2

[0053] In this embodiment, the contact rail channel of the magnetic levitation track beam is installed on the track beam of the curved section, such as Figure 1 to Figure 5 As shown, the track beam contact rail channel positioning mold used in this construction method includes a base plate 1 with a flat structure, and two limiting plates 2 arranged in parallel to each other are arranged on the base plate 1. The upper end of the plate 2 is provided with two positioning grooves 201 matching the width of the channel 3, and the distance between the two positioning grooves 201 on the same limiting plate 2 is the same as the preset position of the two channels 3. The distance is adapted, and a retainer 5 for fixing to the ends of the two channels 3 is also included, so that the channel group composed of the two channels 3 can still be kept parallel to each other after being removed from the limiting plate 2 .

Abstract

The invention relates to the field of track construction and in particular relates to an installation method for conduits of contact rails of magnetism suspension track beams and a positioning mold for the conduits. The method comprises the following steps: manufacturing the positioning mold for the conduits of the contact rails of the track beams; positioning and perforating side formworks of beam boxes; fixing conduit groups; pouring concrete; and dismantling the formworks. The positioning mold for the conduits of the contact rails of the track beams is used for assembling and grouping to enable the parallel construction error of double conduit groups to meet the design requirement; conduit positioning holes formed in external steel formworks of the track beams can enable the deflection construction error of the conduits to meet the design requirement and can also avoid mortar leakage during concrete pouring; and T-shaped bolts on the conduits are connected with the external steel formworks through the positioning holes, the insides of the T-shaped bolts are connected with the conduits, and nuts are tightened to ensure that indentations are tightly jointed with the conduits, thereby eliminating the embedded construction error of the conduits and the oblique construction error of the double conduit groups, ensuring the construction quality of the conduits and ensuring the installation accuracy of the conduits.

Description

technical field [0001] The invention relates to the field of track beam construction, in particular to a method for installing a contact rail channel of a magnetic levitation track beam and a channel positioning mold. Background technique [0002] Maglev train is a kind of train propelled by magnetic levitation force (that is, magnetic attraction and repulsion). The magnetic force of its track makes the train suspend in the air. Unlike other trains, it does not need to touch the track when the train is running. Only affected by the resistance from the air, it is an energy-saving transportation mode with low energy and has great market potential. The magnetic levitation contact rail is the electric receiving track when the maglev train is running. It is located on both sides of the cast-in-place concrete beam. The installation precision of the pre-buried channel of the magnetic levitation track beam contact rail is extremely high. The parallel construction error of the chann...
