Abstract

The invention discloses a guide rail beam and a welding method of the guide rail beam. The welding method comprises the following steps: putting a first rail section and a second rail section on preset positions; fixedly connecting the first rail section to the second rail section through a connecting plate assembly; welding the first rail section to the second rail section; and dismounting the connecting plate assembly. According to the welding method of the guide rail beam disclosed by the invention, the first rail section and the second rail section are positioned preliminarily through the connecting plate assembly, and the first rail section and the second rail section are in welding connection. The welding method is simple in process, easily guarantees welding quality, can improve structural strength of the guide rail beam, and further can effectively overcome adverse effect on a welding process as a result of uncertain factors such as an environment and weather.

Description

technical field

[0001] The invention relates to the technical field of rail transit, in particular to a guide rail beam and a welding method for the guide rail beam. Background technique

[0002] In the related technology, the guide rail beam is divided into multiple sections, and any adjacent two ends are connected together by welding. When welding, most of them are on-site welding. Due to on-site welding, it is easily affected by factors such as the construction environment and weather, resulting in welding The quality is not easy to control, resulting in the welding quality is not easy to control, thus affecting the safety and reliability of the track beam. . Contents of the invention

[0003] The application provides a welding method for a guide rail beam. The welding method for the guide rail beam has the advantages of simple process, easy guarantee of welding quality, and the guide rail beams formed by welding have the advantages of good strength and good stability....
