Problems solved by technology

According to statistics, when using this method to measure the external dimensions of the box girder, at least 8 people are required to cooperate, and auxiliary lines need to be drawn for measurement. The influence of manual operation is large, and the measurement accuracy fluctuates greatly, which is not conducive to accurately grasping the real situation of the box girder being tested

Embodiment 1

[0060] see figure 1 , this embodiment provides a box girder measurement method, the box girder measurement method provided by this embodiment can improve box girder detection accuracy, detection efficiency, save labor cost, and improve labor safety factor.

[0061] The box girder measurement method provided in this embodiment is used to measure the box girder data of the box girder. The box girder has a large volume. The box girder includes a bottom plate, a top plate and two webs, and the two ends of the bottom plate are respectively connected with the two webs. The two ends of the two webs away from the bottom plate are respectively connected in turn to form a closed shape. The end surface of the box girder along the length direction becomes the end interface, and the end interface is roughly trapezoidal.

[0062] When scanning the box girder, the bottom surface of the base plate cannot be scanned, and the bottom surface needs to be fitted after scanning. The box girder is ...

Description

technical field [0001] The invention relates to the field of construction, in particular to a method and device for measuring a box girder. Background technique [0002] At present, the domestic box girder prefabrication field uses manual measurement to measure the external dimensions of the finished prefabricated box girder. According to statistics, when using this method to measure the external dimensions of the box girder, at least 8 people are required to cooperate, and auxiliary lines need to be drawn for measurement. The influence of manual operation is large, and the measurement accuracy fluctuates greatly, which is not conducive to accurately grasping the real situation of the tested box girder. Contents of the invention [0003] The object of the present invention is to provide a box girder measuring method, which can improve the detection accuracy of the box girder, save the labor cost and improve the labor safety factor. [0004] The object of the present inve...
