Extrusion electromagnetic induction type grouting steel bar connecting sleeve
The invention discloses an extrusion electromagnetic induction type grouting steel bar connecting sleeve. Belongs to the field of concrete prefabricated parts. Comprising a water-absorbing expansion sponge, a water-permeable film chamber, an infrared early warning circuit device and an infrared ray electromagnetic induction valve circuit device, the infrared early warning circuit device comprises a protective resistor II, a buzzer, a potentiometer II, a PNP triode II and the like; the infrared ray electromagnetic induction valve circuit device comprises a protective resistor I, a potentiometer I, a PNP triode I, an electromagnetic valve and the like; when cement grout enters the sleeve, the water absorption expansion sponge absorbs water to rapidly expand and extrude the cement grout to the periphery of the reinforcing steel bar to ensure full grouting, and meanwhile, when grouting of the sleeve is completed, the infrared ray electromagnetic induction valve automatically induces to rapidly close the grout inlet and the grout outlet, grout backflow and overflow are prevented, and the connecting quality of the reinforcing steel bar is ensured. The problems of incomplete grouting, backflow, air hole floating and the like of the grouting sleeve are solved, and meanwhile the intelligent grouting sleeve is more intelligent and automatic.
本发明公开了一种挤压电磁感应型灌浆钢筋连接套筒；属于混凝土预制构件领域；包括吸水膨胀海绵、透水薄膜腔室、红外线预警电路装置及红外射线电磁感应阀门电路装置；所述红外线预警电路装置包括保护电阻二、蜂鸣器、电位器二及PNP三极管二等；所述红外射线电磁感应阀门电路装置包括保护电阻一、电位器一、PNP三极管一和电磁阀门等；当水泥浆液进入套筒时，吸水膨胀海绵吸水快速膨胀，挤压水泥浆液在钢筋周围，确保灌浆饱满，同时，当套筒灌浆完毕时，红外射线电磁感应阀门自动感应迅速关闭入浆口和排浆口，防止浆液回流和溢出，确保钢筋连接质量。本发明解决了灌浆套筒存在的灌浆不饱满、回流、气孔上浮等问题，同时更加智能化、自动化。
