Abstract
The invention relates to a large-diameter steel strand extrusion sleeve, which is characterized by comprising an extrusion sleeve and an extrusion sheet, wherein the extrusion sheet is embedded in an inner hole of the extrusion sleeve, the extrusion sleeve is a sleeve barrel with a cylindrical hollow part, the extrusion sheet is embedded in the sleeve barrel and is in a barrel shape with the wall thickness being 1 to 5mm, 1 to 6 grooves are arranged at both ends in the axial direction of the extrusion sheet, the extrusion sleeve and the extrusion sheet are installed before leaving a factory, the construction and the operation are simple, the extrusion sheet cannot easily crack like an extrusion spring because the extrusion sheet is tightly embedded in the extrusion sleeve, the anchoring length of the extruding sheet is ensured to the maximum degree, the extrusion and construction quality is ensured, an extrusion sleeve anchor tool is adopted, the required equipment is simple through being compared with that in the construction adopting a clamp anchor, and the construction cost can be reduced by adopting the extrusion sleeve through being compared with that in construction adopting the clamp sheet anchor.
Description
Technical field
The present invention relates to a kind of major diameter steel strand extruded sleeve that the fixed end ground tackle of the prestress wire special use more than the nominal diameter φ 15mm is used.
Background technology
Infrastructure is all being greatly developed in the whole world now, and China is no exception.Prestress wire is used more and more generally in engineering.Domestic used steel strand diameter now generally is φ 12.7mm and φ 15.2mm, and generally be to be used on house and the bridge, the steel strand that φ 17.8mm and φ 21.6mm are abroad arranged with regard to exploitation in the nineties latter stage, China steel strand producer has also opened these large diameter steel strand that come out successively in recent years. and be mainly used in the bolt support of mine working, seldom use these aspects of bridge construction.The present anchorage style of these major diameter steel strand mainly is to adopt the intermediate plate anchor to come anchoring, the construction technology more complicated, construction cost is also than higher. according to the development of domestic prestressing technique, the major diameter steel strand also can be used on the large foundation construction project, not only stretch-draw end ground tackle consumption is big, and the extruded sleeve consumption of fixed end also can be increasing.
Summary of the invention
Purpose of the present invention is exactly to solve the present situation of no major diameter steel strand fixed end squash type ground tackle now, the extruded sleeve that provides a kind of fixed end ground tackle of special use of energy anchoring nominal diameter φ 22mm prestress wire to use for market.With respect to the intermediate plate anchor of present usefulness, use the extruding anchor height of not only can increasing work efficiency, it is low to reduce construction labour intensity, and can save construction material, safe and reliable.Good economic benefit and social benefit are arranged.
Solution of the present invention is such: the present invention includes extruded sleeve and the extruding plate that is embedded in the extruded sleeve endoporus, described extruded sleeve is the sleeve with cylindrical hollow, inlays extruding plate in the sleeve; Described extruding plate wall thickness is the tubular of 1-5mm, and its every limit, axial two ends has 1-6 bar groove.
Advantage of the present invention is:
1, extruded sleeve and extruding plate all install when dispatching from the factory, and constructing operation is simple;
2, since extruding plate tightly be embedded in the extruded sleeve. unlike adopting Extruding spring like that easy to be cracked, guaranteed the anchorage length of extruding plate to greatest extent, guaranteed to push and construction quality;
3, adopt the extruded sleeve ground tackle. compare and adopt intermediate plate anchor construction equipment needed thereby simple;
4, compare with original spring extruded sleeve, saved and wanted on presstressed reinforcing steel, to put this procedure of helical spring earlier, high efficiency, labour intensity is low, can not cause the injury of finger when the workman installs,
5, compare the construction of employing intermediate plate anchor, adopt extruded sleeve, can reduce construction cost.

The specific embodiment
The present invention includes extruded sleeve 1 and the extruding plate 2 that is embedded in the extruded sleeve endoporus, the sleeve of described extruded sleeve 1 for having cylindrical hollow inlayed extruding plate 2 in the sleeve; Described extruding plate 2 wall thickness are the tubular of 1-5mm, and its every limit, axial two ends has 1-6 bar groove.
The inner radius of described extruding plate 2 one ends is threaded, and the outer wall place of described extruding plate 2 one ends is threaded, and constitutes the inside and outside threaded structure of extruding plate.
The groove that open at described extruding plate 2 axial two ends is to stagger in two ends.
Below with extruded sleeve that can the special use of anchoring nominal diameter φ 22mm prestress wire, the specific embodiment that uses as the fixed end ground tackle in the prestressed anchor.
As shown in Figure 1, extruded sleeve 1 length 60～80mm, being processed with length at sleeve cylindrical two ends is that 1～15mm length, tapering β are 1 °～30 ° tapering chamfering.The sleeve cylindrical has the disc of 1 °～5 ° tapering α for line or belt always, as shown in Figure 2.
Be inlaid with 1-5mm extruding plate 2 in the extruded sleeve, extruding plate 2 length 60～80mm, extruding plate 2 diameter of bores are φ 21.4～φ 25mm; Extruding plate staggers mutually at axial two ends, the external groove A that is processed with 1～6 wide 1～5mm of long 20～70mm in every limit.
Extruding plate 2 endoporus can easily pass nominal diameter φ 22mm prestress wire, are threaded inside and outside extruding plate.Can the machine moulding, also can casting.
When construction, divide 3 procedures; The first step is pressed accompanying drawing 5, and the extruded sleeve of accompanying drawing 1 is placed between extruder roof pressure head 4 and the extrusion die 5, and the major diameter steel strand are passed the extruded sleeve of extrusion die 5 and accompanying drawing 1 from extruder extruder base plate 6 ends, and exposed portions serve pierces into roof pressure head 4 endoporus; Second step, see accompanying drawing 5, keep the extruded sleeve of accompanying drawing 1 consistent with extrusion die 5 axial lines, to extruder oil suction chamber fuel feeding, the extruded sleeve that roof pressure head 4 promotes accompanying drawing 1 pushes in extrusion die 5 by oil pump; The 3rd step, see accompanying drawing 7, continuation is to extruder oil suction chamber fuel feeding, keep of the extruding of the extruded sleeve of accompanying drawing 1 by extrusion die 5, all push through extrusion die 5, make the extruded sleeve of accompanying drawing 1 produce the tight φ 22mm prestress wire 3 of plastic strain crushing extruding plate 2 parcels, thereby form the squash type ground tackle that a steel strand fixed end is used.
