Engineering construction supervision quality accepting and measuring device and method

Abstract

The invention aims to provide an engineering construction supervision quality accepting and measuring device and method. The device comprises a base and an upright, the upper end of the upright is rotatably connected with a rotating disc, a laser rangefinder is arranged on the rotating disc, laser emitting direction of the laser rangefinder is perpendicular to the upright, the rotating disc can rotate along the axial line of the upright, and a stepping motor or a servo motor for driving the rotating disc to rotate is arranged on the upright. The servo motor or the stepping motor is utilized todrive the rotating disc to be in intermittent rotation, the laser rangefinder measures distance each time when rotating by a certain angle and is enabled to realize fan-shaped multipoint distance measuring in a direction of facing a wall surface, and according to a theorem that a vertical section is shortest, minimum numerical value in data is acquired by measuring when laser is most close to beperpendicular to the wall face, and data accuracy and reliability are improved; a base and an upright are utilized for reference positioning, so that deviation is smaller, data acquired by measuring are more stable, and human resources are saved.

Description

technical field [0001] The invention relates to the technical field of engineering supervision, in particular to an actual measurement device and method for quality acceptance inspection of engineering construction supervision. Background technique [0002] At present, the actual measurements in the construction industry generally require more than 2 to 3 people to work together. The surveyors are generally professional in construction and hold certificates after receiving training in actual measurements. There are more than a dozen tools such as leveling rods; the measurement process is complicated, coupled with the analysis and arrangement of later data, the actual measurement of the entire house takes a very long time. However, despite the serious consumption of human resources, the results are still unsatisfactory. [0003] Among them, the laser range finder is used to measure the indoor size or the distance between the walls. When measuring, the laser range finder need...

[0002] At present, the actual measurements in the construction industry generally require more than 2 to 3 people to work together. The surveyors are generally professional in construction and hold certificates after receiving training in actual measurements. More than a dozen tools such as leveling rods; the measurement process is complicated, coupled with the analysis and arrangement of later data, the actual measurement of the entire house takes a very long time

However, despite the serious consumption of human resources, the results are still unsatisfactory

[0003] Among them, the laser range finder is used to measure the indoor size or the distance between the walls. When measuring, the laser range finder needs to align the laser vertically at the target; It is cumbersome to measure the distance on the wall, and the hand-held measurement method cannot guarantee the verticality, which is prone to errors. However, when measuring with itself as the reference point, precise positioning cannot be performed, resulting in low measurement accuracy
