Bolt centering device, assembling method and coordinate measuring method

Abstract

The invention relates to a bolt centering device, and relates to the technical field of engineering construction, the bolt centering device comprises a nut connecting base having the lower part matched with a bolt thread to be centered, a sleeve inserted into the upper part of the nut connecting base and the axis coinciding with the axis of the nut connecting base, and a small prism having a lens rod coaxially inserted into the sleeve. The invention further discloses an assembling method based on the bolt centering device and a coordinate measuring method using the bolt centering device, according to the bolt centering device, the assembling method and the coordinate measuring method, bolt centering work can be efficiently and accurately completed through the bolt centering device. And coordinate measurement of the bolt to be centered is carried out.

Description

Technical field[0001]This application relates to the field of engineering construction technology, and in particular, there is a bolt finding device, assembly method, and coordinate measurement method.Background technique[0002]Currently, in the process of engineering construction, the positional measurement of various embedded bolts are often required. During the position measurement of the pre-buried bolt, since the embedded bolt has a certain diameter, the first need to be used in the next finding of the embedded bolt (ie, the positive center of the forehead end surface of the embedded bolt) is required.[0003]However, in some projects, the amount of pre-buried bolts that need to be measured, the accuracy is high, and the position measurement of the pre-buried bolt is more cumbersome.[0004]At present, the measurement method of the traditional pre-buried bolt is mainly used, that is, the worker uses the size of the end of the bolt end of the ruler, but the measurement of the measure...

Problems solved by technology

[0003] However, in some projects, the number of embedded bolts that need to be measured and positioned is large, the accuracy requirements are high, and there are many types. It is cumbersome to measure and locate the position of embedded bolts

[0004] At present, the traditional pre-embedded bolt measurement method mainly adopts the ruler method, that is, the worker uses a ruler to measure the center of the top surface of the bolt, but the ruler method is inefficient and inaccurate, and is not suitable for a large number of bolts.

After completing the centering of the top surface of the embedded bolt, the construction personnel vertically place the prism at the center point of the top surface of the embedded bolt, and cooperate with the total station to measure the coordinates of the embedded bolt. During this process, the prism needs to be constructed It takes a lot of time and manpower to straighten the personnel in the whole process, and the construction efficiency is low
