Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] A construction measurement method for curved PC track beams, specifically comprising the following steps:

[0019] (1) Before setting out the construction, first calculate the parameters for establishing the three-dimensional model of the track beam (actual beam length, beam height, reverse arch, superelevation, inclination angle, rotation angle and arc) according to the parameters in the instruction book of each beam construction method Line type and other parameters), and then according to the processed data, use computer-a...

Abstract

The invention discloses a curved PC rail beam construction measuring method. A lofting robot and a matched tablet personal computer in communication with the lofting robot are adopted. A created beambody three-dimensional model is imported into the tablet personal computer, and the lofting robot is instructed to perform lofting operation through the tablet personal computer. Procedures of manualcalculation and manual input are saved, an operating process is simplified, and operating efficiency is improved. Due to low manual intervention, probability of miscalculation and input errors are eradicated, and lofting result accuracy is guaranteed. The Trimble lofting robot and the matched tablet personal computer can be further used for detection and creep observation of rail precast beams, labor force is sharply reduced, construction measuring time is shortened, and high construction detection accuracy is realized.

Description

technical field [0001] The invention relates to the construction field of curved PC track beams, in particular to a method for measuring the construction of curved PC track beams. Background technique [0002] The PC track beam of the straddle monorail system is used as both a load-bearing structure and a guiding structure. The dimensions of each part of the beam body must have good accuracy to ensure the linearity and accuracy of the track function. Among them, the linear adjustment of the curved beam and the inspection of the finished beam are the most difficult points of the project, and the measurement requirements are extremely high. The traditional measurement method is to obtain the coordinates and elevation of the target point to be measured and set by reading the map and calculation, and then input the coordinates, elevation, distance, angle and other data of the target point into the instrument to determine the target point on site. The disadvantage of this method...
