Embodiment Construction

[0021] As shown in Fig. 1, Fig. 2 and Fig. 3, an arc-shaped steel track beam is composed of an upper cover plate 101, two opposite webs 102 and a lower cover plate 103 to form a box structure; the box structure is equipped with The upper cover plate 101 has transverse ribs 702 parallel to it, and longitudinal ribs 701 parallel to the web 102 . In addition, a longitudinal rib 703 is provided inside the upper cover 101 . Referring to Fig. 4, the outside of two webs 102 is symmetrically provided with the п-shaped guide beam 704 and the stabilizing beam 705 for cooperating with the light rail guide wheel 105 and the stabilizing wheel 106, and the guiding beam 704 and the stabilizing beam 705 are all made of top plate, web and rib The board is combined, and the deformation correction is made after welding. This arc-shaped steel track beam is mainly used for riding light rail trains. The light rail head and carriage 107 can safely walk on the steel track beam by means of two runnin...

Abstract

The invention provides an arc steel track beam and a manufacturing method thereof, and an upper cover, two web plates which erect relatively and a lower cover in the steel track form box structure which is provided with a horizontal rib plate which is parallel to the upper cover, a longitudinal reinforcing rib which is parallel to the web plates, a guide beam and a stabilizing beam which are matched with the a light rail guide wheel and a stabilizing wheel are arranged symmetrically on the external side of the two web plates; a criss-crossed antiskid groove is evenly arranged on the top surface of the upper cover. The manufacturing method of the arc steel track beam comprises that: the upper cover of the steel track beam is processed, the anti-skid groove is processed, the arc prefabrication of the track beam is done and the track beam is assembled and welded. The invention guarantees the welding deformation amount to be controlled in the maximum amount owing to adopting reasonable technique and welding sequence.

Description

technical field [0001] The invention relates to an arc-shaped steel track beam used for a saddle light rail train and a manufacturing process thereof, and belongs to the technical field of construction machinery processing. Background technique [0002] In the prior art, the track beam of the light rail is usually a prestressed reinforced concrete track beam or a prestressed concrete structure, but the combination of the steel track beam with the main span of the bridge is often required, especially the curved steel track beam with a certain curvature . At present, domestic light rail technology has just started. In addition to the introduction of key technologies of Japanese light rail trains, it is impossible to use the basic engineering of light rail such as various track beams for free, let alone copy and copy. It needs to develop and support independently. Moreover, the existing I-beam track beams are not suitable for riding light rail trains. Contents of the inventi...
