Device and method for measuring roughness of laminated surface of precast concrete member

Abstract

A prefabricated concrete member superposed surface roughness measuring device comprises a rack, a scanning unit, a stepping motor, an information acquisition module and a power supply and controller module, and a circular level is arranged at the top of the rack and used for reflecting whether the rack is horizontally placed or not; a stepping motor, an information acquisition module and a power supply and controller module are distributed on the periphery in the rack, a scanning unit is arranged in a cavity in the rack, two guide grooves with the same height are distributed in the two sides, perpendicular to the scanning unit, of the rack, and limiting stoppers are arranged at the two ends of each guide groove respectively. The stepping motor drives the scanning unit to move in parallel in the direction of the guide groove. The invention further provides a detection method. According to the device and the method, the roughness of the superposed surface of the prefabricated part is measured after the prefabricated part is produced, and a plurality of control indexes are calculated, so that the device and the method for rapidly and accurately measuring whether the roughness of the superposed surface of the prefabricated part meets the requirement are provided.

Description

technical field [0001] The invention relates to a measuring device and method for the roughness of the superimposed surface of a prefabricated concrete member. Background technique [0002] Construction industrialization represented by prefabricated buildings is an inevitable direction for the transformation and upgrading of my country's construction industry. Compared with traditional cast-in-place buildings, prefabricated buildings are more water-saving, material-saving, energy-saving, environmentally friendly and efficient, and can effectively reduce the "carbon emissions" in the construction process. ". Prefabricated buildings can be divided into prefabricated concrete structures, prefabricated steel structures, prefabricated wood structures, etc., among which prefabricated concrete structures account for the largest proportion of applications. There are a large number of prefabricated concrete components such as prefabricated floor slabs and prefabricated beams in prefa...

AI Technical Summary

Problems solved by technology

In actual engineering, there are not only concave grooves but also convex areas on the rough surface. Both concave and convex can improve the bond between prefabricated components and cast-in-place concrete, and concave and convex The area of ​​the area has a greater influence on the cohesive force. Therefore, these factors should be included in the evaluation of the roughness of the superimposed surface. However, the current roughness detection methods mainly focus on the measurement of the depth of the concave and the value of the depth of the concave. The discriminant discriminant has certain limitations on the evaluation of rough surfaces, and there is no fast and accurate superimposed surface roughness measurement and Therefore, it is urgent to develop a measurement method and system for the roughness of the superimposed surface of precast concrete components, which can be used to quickly and accurately measure and evaluate the superimposed surface of precast components roughness
