Abstract

The invention discloses a method for quickly calibrating the standard grouting amount of a semi-grouting sleeve for steel bars on site, which includes an industrial endoscope, a syringe, a water injection hose, a measuring cylinder, a scale tape and a rubber stopper; the sleeve is detected by an injection device Water is injected into the sample, and the volume V from the bottom of the slurry port to the bottom of the sleeve to detect the sample is detected T ; Use a measuring cylinder to measure the volume of the steel bar sample to obtain the volume V of the effective insertion section of the connecting steel bar G , standard grouting volume V inside the sleeve test sample 0 =V T -V G . The invention can quickly and easily calibrate the standard grouting amount of the half-grouting sleeve on site, and has high calibration accuracy.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a method for quickly calibrating the standard grouting amount of a steel half-grouting sleeve on site. Background technique [0002] As a structural form in line with industrial production methods, prefabricated concrete structures have the advantages of fast construction speed, low labor intensity, less noise pollution and wet work, and easy control of product quality. It has become the mainstream development direction of the construction industry at home and abroad. In February 2016, "Several Opinions of the Central Committee of the Communist Party of China and the State Council on Further Strengthening the Management of Urban Planning and Construction" proposed to strive to make the proportion of prefabricated buildings account for 30% of new buildings in about ten years. Raised to unprecedented heights. [0003] In prefabricated building structures, especially in prefa...
