Abstract
The utility model relates to a single rope pre-fastening tool which is composed of a support block 4, an anchor cup 3 and a clamping piece 2 which are orderly tight match and are installed from outer part to inner part. A hood top of the circular hood-shaped support block is provided with a circular hole larger than a steel strand 5 and a notch through from the hood top to the hood bottom, the hood bottom is provided with a step, the end surface of the step is symmetrically provided with twp lifting ring spirals 1, the anchor cup composed of two half edge cylinder bodies with inner conical surfaces is tightly inserted in the support block, the three-piece type tool clamping piece is appressed in the anchor cup, and the taper of the outer side of the three-piece type tool clamping piece oppositely tally with the taper of the anchor cup. The utility model can be placed on the position of any section of steel strands and can do pre-fastening to steel strands, and the utility model has the advantages of convenient installation and disassembly.
Description
The utility model relates to a kind of construction prestressed cable instrument.
In the installation process of prestressed anchor cable anchorage, employed pre-clamping tool is a hydraulic jack, but owing to be subjected to the restriction of jack structure and piston stroke, it can only carry out in the position near steel strand one end end, can not be positioned over steel strand middle parts, for the pretension of steel strand in the continuous lifting process, and suspension cable lashing process in occasions such as steel strand pretension location inapplicable.
The purpose of this utility model is: a kind of any fragment position that is positioned over steel strand is provided, steel strand are carried out pretension, particularly promote the Single rope pre-fastening instrument that the pretension steel strand are used in the construction continuously.
For reaching above-mentioned purpose, the Single rope pre-fastening instrument of the utility model is by anchor plate, anchor cup, the intermediate plate of flush fit installation are formed successively from outside to inside, have one on the cover top of dome shape anchor plate and be slightly larger than the circular hole of steel strand and have one, on the end face of cover tail band step, step two ringbolts are installed symmetrically from covering the top through to the cover recess at the end; The anchor cup of being made up of the half of cylinder of two band internal conical surfaces tightly is inserted in the anchor plate, and three-chip type instrument intermediate plate is close in the anchor cup, and its outside tapering and anchor cup-and-cone degree oppositely coincide.
Owing to adopt said structure, the pre-clamping tool of the utility model can be placed in any fragment position that needs the steel strand of pretension in the construction, and available facility are implemented pretension to it; Also available chain block hooks ringbolt, manually acts on chain block steel strand are applied predetermincd tension.This pre-clamping tool is installed, convenient disassembly; Can be widely used in the occasion that does not need accurately to apply predetermincd tension, particularly in promoting work progress to the pretension of steel strand.
Below, the architectural feature to the utility model is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1: the utility model structural representation (main look, cutaway view)
The A of Fig. 2: Fig. 1 is to view
Embodiment:
As shown in the figure, the Single rope pre-fastening instrument of the utility model is by anchor plate 4, anchor cup 3, the intermediate plate 2 of flush fit installation are formed successively from outside to inside, have one on the cover top of dome shape anchor plate 4 and be slightly larger than the circular hole of steel strand and have one, on the end face of cover tail band step, step two ringbolts 1 are installed symmetrically from covering the top through to the cover recess at the end; The anchor cup of being made up of the half of cylinder of two band internal conical surfaces 3 tightly is inserted in the anchor plate 4, and three-chip type instrument intermediate plate 2 is close in the anchor cup 3, and its outside tapering and anchor cup-and-cone degree oppositely coincide.
During use, earlier steel strand 5 are put into from the indent of anchor plate 4, inserted anchor cup 3, intermediate plate 2 successively, by manually acting on chain block, intermediate plate 2 is bitten steel strand 5, and power is passed to anchor plate 4 by anchor cup 3, chain block drives this device and moves backward, thereby reaches pretension steel strand purpose.During dismounting, loosen chain block, rap anchor plate 4 downwards with iron hammer, anchor plate 4 and anchor cup 3 are broken away from, intermediate plate 2 unclamps steel strand voluntarily, puts from anchor plate 4 indent and takes off steel strand.
