Background technique

Construction project quality inspection is the construction and completion quality inspection of engineering construction, decoration, bridge renovation, equipment installation and other projects. The main technical parameters include verticality inspection, levelness inspection, flatness inspection, diagonal inspection, internal and external angle inspection, and void inspection. Drum detection, etc., the pointer instrument ruler refers to the ruler used to measure verticality and flatness. Verticality detection mainly measures the actual direction of the measured element. To determine whether the reference phase is vertical, press the detection ruler against the measured surface when using it. After the reading on the ruler body panel is stable, read the verticality; levelness detection mainly measures whether the measured element is level. When measuring, place the detection ruler close to the detection surface and observe whether the bubbles of the level tube are centered; flatness refers to the surface of the object being measured. The difference between the unevenness and the absolute level is usually measured using a feeler gauge and a pointer gauge, and the feeler gauge is inserted into the gap for measurement.

At present, most of the pointer instruments and ruler instruments used when measuring the verticality and flatness of walls are on the right side of the ruler. When measuring the corner, that is, the wall is on the right side, and it is inconvenient for the measurer to move his body to the ruler. Readings are performed on the right side, especially when the on-site operator wears a safety helmet, which further increases the difficulty of reading and brings a lot of inconvenience to the quality inspection process of construction projects.

Based on this, it is necessary to study a pointer instrument ruler that can read at multiple angles.
