Abstract

The invention relates to the technical field of grouting sleeve connection, and provides an assembly type building grouting sleeve grouting system which comprises an assembly type building grouting sleeve connecting piece used for connecting steel bars and comprises a first sleeve and a second sleeve; the first sleeve is provided with a first steel bar channel and a second steel bar channel, and the first steel bar channel and the second steel bar channel are both arranged in the axial direction of the first sleeve and located at the two ends of the first sleeve respectively; and the second sleeve is arranged in the first sleeve, a first cavity is formed between the second sleeve and the first sleeve, the second sleeve is provided with a second cavity, the second sleeve is provided with a plurality of discharging ports, one end of each discharging port is communicated with the first cavity, the other ends of the discharging ports are communicated with the second cavity, and the first steel bar channel and the second steel bar channel are both communicated with the second cavity. By means of the technical scheme, the problem that in the prior art, the density of slurry in a grouting sleeve is insufficient, and consequently the reinforcing steel bar connection strength is reduced is solved.

Description

Technical field [0001] The present invention relates to the field of construction grouting sleeve, and in particular, involving an assembled building grouting sleeve grouting system. Background technique [0002] The grouting sleeve is also known as the grouting sleeve joint or the sleeve grouper. The grouting sleeve is a combination of specially processed sleeves, a grouting material and a reinforced bib, and the bonding bite is used to connect the steel bib and the sleeve by injection of the fast-free shrinkage grout when connecting the steel bar. The sleeve grouting joint has the advantages of reliability, wide application, and simple installation. Grouting sleeve connection technology is suitable for reinforced concrete structural engineering, steel structural engineering, bridge engineering, offshore oil mining platform project, offshore wind powerhouse. Grouting sleeve connection technology is a new steel structure connection method due to the needs of engineering practice ...
