Scaffold detection ruler

Abstract

The invention proposes a scaffold detection ruler, and the ruler comprises two square tubes. Each square tube is provided with a chute and a clamping tool, and the clamping tools are in sliding fit with the chutes through adjustable bolts. The two square tubes are rotatingly connected with through a reel. An end part of one square tube is provided with a laser infrared lamp. The surface of each square tube is marked with scale. The reel is marked with an angle. One square tube is provided with a lateral mercury column and a longitudinal mercury column. The beneficial effects of the invention are that the ruble can detect the step pitch and span of a scaffold, a cross bridging angle, a horizontal angle of a big cross bar and the verticality of a vertical rod; the ruler achieves a plurality of purposes, and is high in practicality; the ruler can be folded, is portable, is simple in structure, and is convenient to use.

Description

Technical field [0001] The technical field of inspection tools for building construction of the present invention particularly refers to a scaffold inspection ruler. Background technique [0002] Scaffolding refers to the various supports erected at the construction site for workers to operate and solve vertical and horizontal transportation. They are mainly used on the exterior walls of construction sites, interior decoration, or places with high floors that cannot be directly constructed. It is convenient for construction personnel to work up and down. Peripheral safety net enclosure and high-altitude installation components. It can be seen that scaffolding is an important enveloping structure in the process of building construction, and the inspection of scaffolding is the top priority to ensure the safety and quality of construction. [0003] The inspection content of the scaffold mainly includes the step distance, span, scissor support angle, sweeping pole height, scaffold pi...
