Abstract

The invention relates to the technical field of anti-seismic steel bar detection, and particularly relates to an anti-seismic steel bar longitudinal rib oblique angle measuring device, and overcomes the defect that in the prior art, manual measurement operation is tedious. The device comprises a base and a distance measuring sensor, wherein an n-shaped rack is fixed on the base; a guide rail is installed on the inner wall of the top of the rack in the length direction. A walking motor is arranged on the lower side of the guide rail in a matched mode, a distance measuring sensor is arranged onthe lower side of the walking motor, two distance measuring probes are arranged on the lower side of the distance measuring sensor, a supporting strip parallel to the guide rail is fixed to the base,clamping frames parallel to the supporting strip are arranged on the two sides of the supporting strip respectively, and a plurality of vertical guide shafts are rotationally connected to the clampingframes. The positions of longitudinal rib protrusions can be detected through the two side-by-side distance measuring probes, manual measurement is not needed, the operation is easy and convenient, the errors are low, the two rows of guide shafts are arranged on the lower sides of the distance measuring sensors, reinforcing steel bars can be guided forwards in the guide rail direction, and it isguaranteed that the reinforcing steel bars move forwards smoothly.

Description

technical field [0001] The invention relates to the technical field of anti-seismic steel bar detection, in particular to a device for measuring the oblique angle of longitudinal ribs of anti-seismic steel bars. Background technique [0002] Steel for reinforced concrete and prestressed reinforced concrete, with a circular cross-section, sometimes square with rounded corners. HRB400E-Z steel bar refers to a hot-rolled ribbed grade IV steel bar specified in the national standard GB1499.2-2018 "Hot-rolled Ribbed Steel Bar for Reinforced Concrete", formerly known as Grade IV steel bar, with a yield strength of not less than 400Mpa. Ribbed steel bars usually have two longitudinal ribs and transverse ribs evenly distributed along the length direction. Rebar is a small section steel, which is mainly used for the skeleton of reinforced concrete building components. The consistency of the longitudinal rib angle has a certain degree of mechanical strength and bending Deformation per...
