Combination formed connecting grouting sleeve and manufacturing method thereof

Abstract

A combination formed connecting grouting sleeve comprises two to eight connecting sleeve assemblies which are each of a separating structure, positioning plates and sealing rings. Under the using state, the two to eight connecting sleeve assemblies are fixedly connected into an overall tubular connecting sleeve in a welding or bolt connecting mode, the positioning plates are located in the middlesof the tubular connecting sleeve, and the sealing rings are correspondingly located at the two ends of the tubular connecting sleeve; the inner surface of each connecting sleeve assembly of the separating structure is provided with a protruding rib, a boss or a protruding circle and a groove or a pit, wherein the protruding rib, the boss or the protruding circle and the groove or the pit are formed by punching, and the groove or the pit are corresponding to the outer surface; and the middles of all the connecting sleeve assemblies are provided with the positioning plates fixedly connected ina welded mode. According to the combination formed connecting grouting sleeve, the production technology is simple, convenient and environmentally friendly, automated production of an assembly line can be achieved, the production cost is low, the product quality and the production efficiency of the connecting grouting sleeve can be improved, and structural safety of a steel bar butting grouting anchor connecting joint is ensured.

Description

technical field [0001] The invention relates to a connecting grouting sleeve and a manufacturing method thereof, in particular to a combined molding connecting grouting sleeve and a manufacturing method thereof. Background technique [0002] With the development of prefabricated concrete structures in China, the connection methods and connection products of the main stressed steel bars between the prefabricated components are various, and the technology is becoming more and more mature. The ends of the two connected steel bars are inserted into the connecting grouting sleeve, and the gap is filled with grouting material. Since the outer surface of the steel bar and the inner surface of the sleeve each have distributed transverse ribs, the grouting material is composed of high-performance cement mortar or epoxy mortar After solidification, the three are embedded and occluded to realize the connection. There are two ways of making grouting sleeves in the market: machining aft...
