A grouting sleeve processing device

Abstract

The invention provides a grouting sleeve machining device. The grouting sleeve machining device comprises a fixing sleeve (1), a nicking mechanism and a connecting disc (3); the nicking mechanism comprises a first clamping plate (21), a second clamping plate (22) and a nicking plate (23); the first clamping plate (21) is fixedly arranged outside the fixing sleeve (1); and the nicking plate (23) isfixed to the first clamping plate (21) through a pin shaft, and one end of the nicking plate (23) stretches into a cavity of the fixing sleeve (1) through a notch groove formed in the fixing sleeve (1). A grouting sleeve is formed at a time when being machined through the grouting sleeve machining device, the structure is simple, and the working efficiency of machining the grouting sleeve is effectively improved; under the premise that the rigidity of a sleeve body is met, the wall thickness of the sleeve body can be decreased properly through the grouting sleeve manufactured by the groutingsleeve machining device, and thus materials are saved; and meanwhile, the wall thickness is decreased under the situation of the same outer diameter, grouting materials are increased, thus grouting ismore dense, and bonding performance is higher.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a grouting sleeve processing device. Background technique [0002] In the prior art, the steel bar connection between the prefabricated concrete building parts needs to be connected by sleeve grouting. The two connected steel bars are inserted into the metal sleeve and high-performance cement mortar is poured into the gap between the sleeve and the steel bar. After the cement mortar is hardened, the three are embedded with each other to realize the connection of the steel bars. The traditional grouting sleeve is provided with protruding anchors on the inner wall of the sleeve. The common method is to weld the anchors to the inner wall of the sleeve or open a mold to cast the anchors and the casing as one. The processing methods of these anchors are not only relatively Complicated and time consuming. There is also no device for processing the groutin...

Problems solved by technology

[0003] In order to overcome the traditional grouting sleeve processing complex, time-consuming and material-consuming problems, the invention provides a grouting sleeve processing device, the grouting sleeve processing device includes a fixed sleeve, a scoring mechanism and a connecting plate, the scoring The mechanism includes a first clamping plate, a second clamping plate and a scoring plate; the first clamping plate is fixedly arranged outside the fixing sleeve, the scoring plate is fixed on the first clamping plate through a pin shaft, and one end of the scoring plate is fixed by The gap provided on the sleeve extends into the cavity of the fixed sleeve, the other end of the scoring plate is connected to the second splint through the pin shaft, the second splint and the connecting plate are hinged through the connecting plate, and one end of the fixed sleeve is provided with Hydraulic cylinder, the hydraulic rod protruding from the hydraulic cylinder is connected to the connecting plate; when making the grouting sleeve, put the seamless steel pipe of appropriate length into the fixed sleeve cavity, start the hydraulic cylinder, and the hydraulic rod of the hydraulic cylinder stretches out to drive The scoring mechanism moves, the scoring plate rotates, and the part of the scoring plate that extends into the cavity of the fixed sleeve through the gap dents the seamless steel pipe, restores the hydraulic cylinder, and the hydraulic rod retracts to drive the scoring mechanism to reset. The seamless steel pipe with dents can be taken out to complete the processing process
