Abstract

The invention discloses a manufacture method for a maglev track beam. The manufacture method comprises the following steps: tying a framework of steel reinforcement, manufacturing an internal mold, putting the internal mold in the framework of steel reinforcement, mounting a formwork of track beam, and regulating the formwork of track beam so as to meet the required linearity. The lateral displacement relative to the track beam and the perpendicularity relative to a bottom mold of the side mold of the formwork of track beam can be regulated through a regulating component, and a translating component arranged outside end molds is used for regulating the longitudinal movement relative to the side mold of each end mold. The manufacture method has the advantages of being easy to operate, high in regulating precision and simple to assemble and disassemble the molds. A control component can respectively regulate the transverse displacement, the longitudinal displacement and the vertical displacement of the track beam, the linearity precision can achieve the range of + / -5, and the precast quality of a curved track beam is ensured. The intelligent control can realize high regulating precision, high efficiency and good reliability of a formwork system, and the manufacture method is particularly applicable to precasting of medium-low-speed maglev linear or curved track beams.

Description

technical field [0001] The invention relates to the field of bridge design and construction, in particular to a method for manufacturing a maglev track beam. Background technique [0002] Compared with ordinary wheel-rail trains, medium and low-speed maglev trains have the characteristics of low noise, small vibration, no pollution, and small turning radius. They are known as "zero-height aircraft". And an important symbol of industrial level. The design, manufacture and construction technology of the maglev track beams used by medium and low speed maglev trains has always been a technical difficulty. Among them, the main characteristics of the track beam prefabrication project of maglev technology are as follows: [0003] 1) The technical content is high, the manufacturing technology of the track beam, the durable concrete construction technology, the tensioning process, the transportation technology, the overcoming of the concrete creep and the arching and the installati...
