Abstract
The utility model provides a squeezing type anchor tool used for lengthening prestressing tendon through using a coupler body jointly, embedded type anchorage, and non-stretching end anchorage. The utility model is composed of a pressing sleeve, steel strands or steel wires of high tensile strength. Screw threads through quenching treatment or uniformly distributed convex thorns are arranged in the inner side of inner holes of the pressing sleeve. Taper angles of strike are arranged at both ends of the inner holes of the pressing sleeve. The utility model has the advantages of simple structure, and convenient construction.
Description
The utility model relates to the end anchor firmware of presstressed reinforcing steel in a kind of prestress engineering construction, the presstressed reinforcing steel that is used to extend (being used with the connection body), flush type anchoring, the anchoring of non-stretch-draw end.
Adopt more bulb-end anchorage and wedge shape anchor in the construction of pre existing stress engineering, be mainly used in the stretch-draw and the anchoring of stretch-draw end, the former only limits to the anchoring steel wire, complex process in the construction, the latter only is used for the stretch-draw end anchoring of presstressed reinforcing steel, can not be used with hookup, is unsuitable for the flush type anchoring.Other has a kind of ground tackle, by the steel extruded sleeve, increase the cover that rubs, steel strand or high tensile steel wire group or, when the ground tackle steel strand, its formation is to be set with one to increase the cover that rubs by what hard metal was made outside steel strand, increasing that the cover that rubs is outer to be set with a steel extruded sleeve; When the anchoring high tensile steel wire, wherein or being set with of being made by hard metal outside core wire increases the stamen cover that rubs, peripheral steel wire then is with one outward and increases the cover that rubs, increase outside the cover that rubs and be set with a steel extruded sleeve, increase the cover that rubs and be open type or opposite opened, it is perverse that its surfaces externally and internally is shaped on uniform profile of tooth.Its weak point is because perverse the increasing of a uniform profile of tooth of the surfaces externally and internally cover that rubs is set separately, complex structure, and construction is inconvenient.
The purpose of this utility model provides a kind of squash type ground tackle of simple in structure and easy construction.
The utility model can be realized by following measure:
This squash type ground tackle is made up of extruded sleeve, steel strand or high tensile steel wire, and the inboard of the endoporus of extruded sleeve is shaped on through the screw thread of Quenching Treatment or uniform convex perverse.
The purpose of this utility model also can realize by following measure:
Two ends at the endoporus of extruded sleeve are provided with the tapering angle of strike.
After the steel strand of dressing up one or high tensile steel wire, extruded sleeve are packed extrusion die into, through extruding, the extruded sleeve exhibition of being forced to is long, steel strand or high tensile steel wire external surface are gone in screw thread on the extruded sleeve or the uniform perverse embedding of convex (perverse) simultaneously, can't slippage thereby steel strand or high tensile steel wire and extruded sleeve are firmly tightened together.
The endoporus of extruded sleeve oozes Quenching Treatment altogether by carbon, nitrogen, thereby guaranteeing that its screw thread or convex are perverse has high strength and steel strand or high tensile steel wire external surface are gone in directly embedding (perverse), and is simple in structure, cost is low, easy construction had both reduced working procedure, had reduced construction cost again.Because the two ends at the endoporus of extruded sleeve are provided with the tapering angle of strike.Thereby help the extension of steel strand and bring convenience to construction.
Fig. 1 is a structural representation of the present utility model.
Be described further with reference to the accompanying drawings:
At first extruded sleeve 3 is sleeved on steel strand or high tensile steel wire 5, pressed from mould 1 then, extruded sleeve 3 exhibition of being forced to is long, screw thread on its endoporus or uniform convex sting that steel strand or high tensile steel wire appearance are gone in 4 embeddings (perverse) and.Both promptly closely are connected into one.In addition, be provided with tapering angle of strike 2 at the two ends of the endoporus of extruded sleeve 3.
Claims (2)
1. a squash type ground tackle is made up of extruded sleeve, steel strand or high tensile steel wire, it is characterized in that the inboard of the endoporus of extruded sleeve (3) is shaped on through the screw thread of Quenching Treatment or uniform convex thorn (4).
2. a kind of squash type ground tackle according to claim 1 is characterized in that the two ends of the endoporus of extruded sleeve (3) are provided with tapering angle of strike (2).
