A semi-grouting sleeve connection structure of assembled components

Abstract

The invention discloses a prefabricated member semi-grouting sleeve connection structure, which comprises a barrel body, wherein a through groove is formed in the barrel body, a slurry feeding openingand a slurry discharging opening which penetrate through the through groove are arranged on an outer lateral wall of the barrel body, a threaded installation hole is formed at one end of the barrel body, a rubber sealing ring is arranged at the other end of the barrel body, a stirring part is arranged in the barrel body, the stirring part is in a hollow sleeve shape, a first fixed rod and a second fixed rod are arranged in the lateral direction of the stirring part, the first fixed rod extends out of the slurry feeding opening, the second fixed rod extends out of the slurry discharging opening, and the first fixed rod and the second fixed rod are used for driving the stirring part to rotate. As the stirring part is arranged in the semi-grouting sleeve, cement in the barrel body can be even by rotating the stirring part, and the barrel body can be fully filled with the cement; the first fixed rod or the second fixed rod serves as a driving part of the stirring part, and the first fixedrod and the second fixed rod extend out of the slurry feeding opening and the slurry discharging opening; thus, convenience is brought to operation when the first fixed rod and the second fixed rod are driven.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a semi-grouting sleeve connection structure of assembled components. Background technique [0002] The prefabricated large slab straight column grouting sleeve foundation consists of two parts: prefabricated concrete base column and bottom plate. The bottom of the base column adopts a grouting sleeve structure, and the anchor bar corresponding to the base column is pre-embedded in the middle of the base plate. When the center of the base column is aligned with the anchor bar of the bottom plate and inserted, inject high-strength fine stone concrete through the grouting hole in the grouting sleeve structure to fill the cavity between the sleeve and the bottom plate. When the grout hole overflows, the grouting is completed. pulp. After curing, the base column is firmly connected with the bottom plate. Under the condition of keeping the bottom plate unchanged, the buried depth of...

AI Technical Summary

Problems solved by technology

In the existing semi-grouting sleeve, the grouting cement has pores due to the existence of gravel during the grouting process, and the grouting cement is not tight, which reduces the stability of the sleeve connection structure
