Abstract

The invention relates to a prestressed clip installer and its usage method, which relate to the technical field of prestressed building construction. Aiming at the problem that the current manual installation of clips affects the construction quality and construction progress. It includes: the main rod, which is a hollow sleeve and is sleeved outside the steel strand, and the outer wall of the main rod is provided with more than two guide rails along the axial direction, and the guide rails are evenly distributed along the radial direction of the main rod; the clip introducer, whose Connected to the bottom end of the main rod and coaxial with the main rod, the inner diameter of the clip introducer is the same as the inner diameter of the main rod, and its outer diameter is smaller than the outer diameter of the main rod, and the guide rail of the main rod extends to the bottom of the clip introducer; Hammer, wherein the hollow cavity is provided with a limit card slot corresponding to the guide rail, so that the hammer can be sleeved on the main rod and slide along the guide rail, and a control mechanism, which is connected to the top of the main rod, is used for knocking The hammer is fixed on the upper part of the main rod, and the hammer is released to slide down the guide rail and knock the clip into the tapered hole of the anchor ring.

Description

technical field [0001] The invention relates to the technical field of prestressed building construction, in particular to a prestressed clip installer and a usage method thereof. Background technique [0002] In prestressed construction, clip-type anchors are commonly used, which use the wedge-tightening principle of the tapered hole to anchor the steel strand bundle, that is, the wedge-shaped clip anchors the steel strand bundle in the tapered hole of the anchor ring. After the steel strand bundle is stretched by a jack and reaches the design stress value, the jack is slowly released, and the clip is brought into the tapered hole of the anchor plate by the uniformly retracted steel strand bundle to form an anchoring unit. The stress is transmitted to the building structure through the anchor ring and the anchor plate, thus forming a permanent prestress; among them, the clip is the key part of the anchorage system, and the clip is generally in the shape of a circular cone, ...
