Abstract
The invention discloses a grouting anchor type rebar connection sleeve and a manufacturing method of the grouting anchor type rebar connection sleeve. The grouting anchor type rebar connection sleeve is characterized in that a through hole is formed in a sleeve body, elastic rubber rings are installed at two ends of the through hole, and the sleeve body is provided with a grouting material feed inlet and a grouting material discharge outlet. The manufacturing method of the grouting anchor type rebar connection sleeve comprises the following steps that (1), a machining raw material is a low-carbon steel or low-alloy steel seamless steel tube; (2), a machine tool is adopted to machine internal threads in a turning mode from outside to inside from the two sides of the steel tube; (3), the feed inlet and the discharge outlet are drilled in the positions, about 20 mm away from the ends, of the two ends of the steel tube, and are each about 10 mm in diameter; (4), the two ends of the steel tube are sleeved with the rubber sealing rings. The seamless steel tube is adopted, the intensity is high, plasticity is good, quality is stable, the use amount of materials is small, and as the method for machining the threads on the inner wall of the steel tube is adopted, compared with an abroad casting process and a domestic steel bar cutting process, the manufacturing method has the advantages that the degree of mechanization is high, the amount of machining is small, production efficiency is high, and the cost of the sleeve is lowered greatly.
Description
Technical field
The present invention relates to reinforced concrete technology field, particularly a kind of slurry anchor formula reinforcing steel bar connecting sleeve tube and manufacture method thereof.
Background technology
In traditional cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect more, be welded to connect or the mechanical joining methods such as compression sleeve, and construction method is comparatively complicated, and must complete before fluid concrete, the connection of reinforcing bar, can not carry out fabricated construction.At present, in the concrete construction of practical set formula, the reinforcing steel bar connecting sleeve tube of employing is steel-casting, ironcasting, and the machine cut mode workpiece of rod iron or thick walled steel tube, and as reached corresponding technical requirements, processing and fabricating cost is all higher.
Summary of the invention
The object of the present invention is to provide a kind of for the bar connecting between monomer bar connecting and assembly concrete building prefabricated components, the butt end of two connecting reinforcements is combined into slurry anchor formula reinforcing steel bar connecting sleeve tube and the manufacture method thereof of a connector by branch sleeve and the cement mortar of pouring into its internal voids.
The present invention realizes like this, it comprises sleeve body, elastic rubber sealing ring, grouting material plup inlet and grouting material discharge opening, it is characterized in that: be provided with through hole in sleeve body, elastic rubber ring is equipped with at through hole two ends, and sleeve body is provided with grouting material feeding mouth and grouting material discharging opening.
The internal whorl of described slurry anchor formula reinforcing steel bar connecting sleeve tube is spirality, adopt machine tooling form, internal whorl be configured to thread depth 1 ~ 5mm, flight pitch 1 ~ 5mm.
The processing method of slurry anchor formula reinforcing steel bar connecting sleeve tube comprises the steps:
(1) process raw material employing mild steel or low-alloy steel seamless steel pipe;
(2) machining tool is adopted to go out internal whorl from steel pipe both sides ecto-entad car;
(3) feeding mouth that drill diameter is about 10mm and discharging opening is located at steel pipe two ends far from termination about 20mm;
(4) rubber seal ring on the cover of steel pipe two ends.
The present invention adopts the reinforcing bar of slurry anchor formula reinforcing steel bar connecting sleeve tube to monomer reinforcing bar or prefabricated assembled concrete component to connect.Be characterized in the sleeve of same diameter series bar connecting and close diameter series bar connecting, adopt mild steel or low-alloy steel seamless steel pipe, process internal whorl thus formation slurry anchor formula reinforcing steel bar connecting sleeve tube by tool special at steel pipe inner wall.Compare with the rod iron of domestic current employing with the cast iron abroad adopted, the present invention adopts seamless steel pipe, not only intensity is high, plasticity is good, and steady quality, and material usage is few, and adopt the method in steel pipe inner wall machining screw, compare with domestic rod iron Cutting Process with external casting technique, mechanization degree is high, and processing capacity is few, production efficiency is high, thus can significantly reduce sleeve cost.
