Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that the drawings are in a very simplified form and all use imprecise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. For the convenience of description, the "up" and "down" mentioned below are consistent with the upper and lower directions of the drawings, but this cannot be a limitation of the technical solution of the present invention.

[0039] Combine Figure 1 to Figure 10 Describe the pre-stressed clip installer of the present invention, which includes:

[0040] The main pole 10 is a hollow sleeve and can be sleeved outside the steel strand 3, the outer wall of the main pole 10 is provided with more than two guide rails 11 along its axis, and the guide rails 11 are uniformly distributed along the radial direction of the main pole 10. The ...

Abstract

The invention relates to a prestressed clamping piece installer and a using method thereof, and relates to the technical field of prestressed building construction, aiming at solving the problem thatthe existing artificial clamping piece installation way affects construction quality and construction progress. The prestressed clamping piece installer comprises a main rod, a clamping piece introducer, a knocking hammer and a control mechanism, wherein the main rod is a hollow sleeve and sleeves a steel strand; two or more guide rails are arranged on the outer wall of the main rod along the axisdirection, and are evenly distributed along the radial direction of the main rod; the clamping piece introducer is connected with the bottom end of the main rod and is coaxial with the main rod; theinner diameter of the clamping piece introducer is equal to that of the main rod, and the outer diameter of the clamping piece introducer is smaller than that of the main rod; a guide rail of the mainrod extends to the bottom end of the clamping piece introducer; a hollow inner cavity of the knocking hammer is provided with a limiting clamp groove corresponding to the guide rail, so that the knocking hammer can sleeve the main rod and slide along the guide rail; the control mechanism is connected with the top end of the main rod, is used for fixing the knocking hammer at the upper part of themain rod, and loosens the knocking hammer to enable the knocking hammer to slide down along the guide rail so as to enable a clamping piece to be knocked into a taper hole of an 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 use method thereof. Background technique [0002] In pre-stress construction, clip-type anchors are commonly used, which use the wedge principle of tapered holes to anchor the steel stranded wire bundle, that is, the wedge-shaped clip anchors the steel stranded wire bundle in the tapered hole of the anchor ring. After the steel stranded wire harness is stretched by the 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 retracting steel stranded wire harness to form an anchor unit, the steel stranded wire harness The stress is transmitted to the building structure through the anchor ring and the anchor plate, thereby forming a permanent prestress; among them, the clip is the key part of the anchor system, and the clip is gen...
