Problems solved by technology

The disadvantage of this indentation machine is that the indentation formed instantly by the two steel circular discs is easy to recover, resulting in the indentation on the plastic sheath of the slow bonded prestressed tendon is not obvious, and the bonding effect between the external concrete and the external concrete is not good during use. it is good

Abstract

The invention discloses a slow bonding prestressed tendon outer coated sheath indenting machine, comprising a machine body, a rack driving device and a mould pressing device; the top of the machine body is a horizontal worktop, the horizontal worktop is provided with a longitudinal elongated slot; the mould pressing device comprises four fixed axle which are fixed on the worktop and in rectangulardistribution, a right hexagonal prism and a horizontal ring module chain, the module chain comprises a plurality of modules, the bottom of the module forms a rack, the broad side of the module is provided with a plurality of large arc grooves and small arc grooves along the horizontal direction, the large and small arc grooves are alternately arranged, adjacent modules are connected with upper and lower module connecting pieces by rivets, adjacent straight line parts of two horizontal ring module chains are parallel and in contact fit, thus forming a processing part, and the longitudinal elongated slot on the horizontal worktop is arranged below the processing part. When in use, the slow bonding prestressed tendon outer coated sheath intending machine of the invention ensures intending effect of slow bonding prestressed tendon.

Description

technical field [0001] The invention relates to an indentation machine for a slow bonded prestressed tendon sheath. Background technique [0002] Slowly bonded prestressed tendons have simple and easy process characteristics in use, and have excellent mechanical properties. Therefore, slow bonded prestressed tendons have been paid more and more attention. The slow-bonding prestressed tendons are provided with a plastic sheath on the outer side of the prestressed steel bars, and a slow-bonded gelling agent is sandwiched between the plastic sheath and the prestressed steel bars. In order to make the plastic sheath of slow-bonding prestressed tendons bond firmly with the external concrete, indentations are processed on the surface of the plastic sheath. At present, the indentation machine for the outer sheath of slow bonded prestressed tendons includes: two steel circular turntables, which are evenly equipped with several corrugated teeth with concave arc-shaped end faces alon...
