Reinforced full-grouting sleeve and casting modeling method thereof

Abstract

The invention provides a reinforced full-grouting sleeve and a casting modeling method thereof. The reinforced full-grouting sleeve comprises a sleeve body, a grouting opening and a grout outlet; four reinforcing ribs which are sunken towards the center of the sleeve body are arranged on the side face of the sleeve body and located between the grouting opening and the grout outlet; the inner walls of the reinforcing ribs are ellipsoidal surfaces; the highest convex points of the ellipsoidal surfaces form limiting shoulders used for limiting the ends of steel bars; a plurality of reinforcing rings are arranged on the side face of the sleeve body, and the reinforcing rings and the reinforcing ribs are distributed at intervals; and thickened sleeve shoulders are arranged outside the two ends of the sleeve body. According to the casting modeling method of the reinforced full-grouting sleeve, a plurality of first solid inner cores, a plurality of second solid inner cores and an outer mold are connected in an assembled mode to form a casting cavity, casting is conducted through the procedures of hot fluid positioning, release agent synchronous spraying, vibration demolding and the like, the production efficiency is high, and the mold utilization rate is also high. The reinforced full-grouting sleeve is reasonable in design, simple in structure and process, high in utilization rate and suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of grouting sleeve production, in particular to a reinforced full-grouting sleeve and a casting molding method thereof. Background technique [0002] Grouting sleeve is also called grouting sleeve joint or sleeve grouting joint. The grouting sleeve connection technology is suitable for reinforced concrete structure engineering, steel structure engineering, bridge engineering, offshore oil exploration platform engineering, offshore wind power towers and other fields. Grouting sleeve connection technology is a new steel structure connection method due to the needs of engineering practice and technological development. The emergence of this connection method makes up for the shortcomings of traditional steel structure connection methods (mainly including welding and bolt connections). And has been developed and applied rapidly. Grouting sleeves can be divided into casting grouting sleeves and machined groutin...

AI Technical Summary

Problems solved by technology

However, the existing full-grouting sleeve has a simple structure and low strength, and the conduction effect of the slurry inside it is not good, and air bubbles are prone to occur, which increases the workload of grouting

Furthermore, the inner mold of the existing full-grouting casting sleeve uses a sand core, and the casting efficiency of the outer mold and the sand core inner mold is low, the work intensity is high, and the production cycle is long, which is not conducive to improving production efficiency
