Problems solved by technology

This independent tool positioning method can solve three technical problems at the same time: one is the poor position accuracy of the embedded parts caused by the assembly of the T-beam prefabricated formwork, and the other is the deformation of the T-beam prefabricated formwork when the concrete is vibrated The problem of the deviation of the position of the embedded parts is caused, and the third is the problem of the deviation of the embedded parts caused by the pushing of the concrete when vibrating the concrete, thus improving the positioning accuracy of the embedded parts

Embodiment Construction

[0034] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0035] The existing positioning method of the embedded part 2 is to fix the embedded part 2 on the prefabricated template. When the T-beam prefabricated formwork is assembled, it will cause errors in the position of the embedded part 2; when the concrete is vibrated, the deformation of the T-beam prefabricated formwork will also cause the position of the embedded part 2 to deviate from the predetermined position; at the same time, due to the pushing of the concrete, It will also cause the embedded part 2 to shift. As a result, the positioning accuracy of the embedded part 2 is poor and deviates from the predetermined position. As a result, when the sidewalk is installed, the embedded part 2 needs to be corrected, and it needs to be matched or even installed on site. After installation, the sidewalk has structural internal stress, low installati...

Abstract

The invention relates to a positioning method and a positioning tool for an embedded part of a T-beam sidewalk. An embedded part position error caused by the assembly of a T-beam prefabricated formwork and embedded part position deviation caused by vibrating concrete are avoided by adopting an independent tool positioning manner, so that the positioning precision of the embedded part is guaranteed, the internal stress during installation of sidewalk parts and structural damage caused by cutting and chambering are reduced, and the safety of a sidewalk structure is improved; the correction workof the embedded part is reduced, and the sidewalk installation efficiency is improved; and the straightness and attractiveness of the sidewalk are improved.

Description

technical field [0001] The invention relates to the field of railway and road and bridge construction, in particular to a positioning method and a positioning tool for embedded parts of T-beam sidewalks. Background technique [0002] During the prefabrication of railway concrete T-beams, the embedded parts used to install the sidewalk need to be prefabricated in the concrete. The current positioning technology for embedded parts is: simple positioning by opening U-shaped openings on the prefabricated formwork of railway concrete T-beams. There are certain errors in the assembly of railway concrete T-beam prefabricated formwork. In addition, the concrete needs to be vibrated during the prefabrication process of railway concrete T-beam. The position of the part deviates from the predetermined position. The actual measurement found that the positioning of the embedded part is too simple, resulting in a large position error in the six degrees of freedom of the embedded part in s...
