Problems solved by technology

Although the above detection ruler can be applied to the formwork support system, it can only measure the flatness and verticality of the two measurement points of the upper and lower legs. If the measurement point has a concave or convex surface with flatness deviation, the measured value often deviates Larger, thus affecting the determination of the measurement results
At the same time, if an outrigger is directly added to the main body of the test ruler for detection in order to increase the measurement point, the position of the outrigger is fixed and cannot be adjusted.
In actual operation, since the wall stud formwork needs to be reinforced with wooden squares, drawing rods, angle steel and other tools when fixing the wall stud formwork, when the above-mentioned detection ruler is used to detect the verticality of the wall stud formwork, it usually happens that the outrigger just aligns with the wood. The situation of the square, thus affecting the use of the detection ruler

Abstract

The invention discloses a detection ruler for perpendicularity, flatness and levelness of wall columns and a detection method thereof. The detection ruler includes a main ruler body, multiple measurement ruler bodies positioned on the same side are rotatably installed on the main ruler body in the length direction at intervals and can be fixed when rotating to the positions perpendicular to the main ruler body; at least one measurement ruler body positioned in the middle can slide on the main ruler body and be fixed. When the detection ruler is used for detecting the perpendicularity of a wallcolumn, the outer end faces of the measurement ruler bodies are aligned to the surface of the wall column, a string pendant is fixed to the measurement ruler body at the top, and then by reading thevalues, corresponding to each measurement ruler body, of a string, the perpendicularity is determined. By means of the detection ruler for the perpendicularity, flatness and levelness of the wall columns and the detection method thereof, multi-point location detection can be conducted on wall column templates and the surfaces of the wall columns after pouring, the detection result is precise, andthe detection method is simple and high in detection speed.

Description

technical field [0001] The invention relates to a building detection ruler, in particular to a wall column verticality, flatness and levelness detection ruler and a detection method thereof. Background technique [0002] After the wall column construction is completed, in order to check whether the quality of the wall column is up to standard, it is usually necessary to use a ruler to detect the verticality, levelness and flatness of the wall column. When the deviation is detected, the engineering quality problem has already appeared, and the post-processing is very troublesome. Based on the above reasons, in order to reduce the quality problems of the project and avoid repairing the wall columns in the later stage, the applicant considers to test the verticality, levelness and flatness of the wall column formwork after the formwork support system is erected and before concrete pouring, and After the wall column is poured, the wall column is re-inspected to improve the cons...
