Abstract

The invention relates to a prestressed and non-prestressed heat-shrinkable sleeve anti-corrosion anchor rod. The number of main reinforcing steel bars of the anchor rod is 1 to 5; when the main reinforcing steel bars are connected through connecting nuts, the connecting nuts connect the main reinforcing steel bars of the anchor rod to the rated length, and the main reinforcing steel bars of the anchor rod are finish-rolled deformed steel bars; nut connectors or / and the main reinforcing steel bars of the anchor rod are all sleeved with thermoplastic film sleeves; and then concrete curing materials are poured into the main reinforcing steel bars and the connecting nuts with the thermoplastic film sleeves.

Description

technical field [0001] The invention relates to an anti-corrosion structure of an anchor rod and a connection structure of the anchor rod, in particular to a heat-shrinkable sleeve shrinking a prestressed and non-prestressed anchor rod main tendon. Background technique [0002] There are also many types of anchors, such as single main steel bars, anchors with multiple main steel bars, etc.; anchors using main steel bars are used more and more, especially in buildings, roads, and track construction. The anti-corrosion requirements of the connection structure are getting higher and higher; the waterproof and anti-corrosion requirements of the anti-floating anchors are high. In view of the large number of anti-floating anchors and the small diameter, it is difficult to handle the joints of the anti-floating anchors, which has always been a pain point in the application of anchors. The durability measures of the anti-floating anchor mainly include: the thickness of the protectiv...
