Abstract

The utility model discloses a prestressed steel wire self-anchored anchoring fixture, and in particular relates to an anchoring fixture which is applicable to steel wires with the diameter phi ranges from 3 to 11. The anchoring fixture comprises an anchor ring with a cylindrical inner cone hole, and a cone-shaped clamping piece which is matched with the anchor ring inner cone hole, wherein the clamping piece inner hole is provided with screw teeth; the outer circle diameter size phi A of the anchor ring ranges from 26mm to 34mm, the height size H ranges from 28mm to 36mm, the bottom hole diameter phi B ranges from 10mm to 13mm, the larger end diameter phi C of the cone hole ranges from 16mm to 21mm, the angle alpha ranges from 12 degrees to 16 degrees, the larger diameter phi A1 of the larger end of the clamping piece ranges from 16mm to 21mm, the total length H1 ranges from 25mm to 33mm, the angle alpha 1 ranges from 12 degrees and 20 arc min to 16 degrees and 20 arc min, and the thread M ranges from M3*0.35 to M11*1. The anchoring fixture disclosed by the utility model has the advantages that firstly, the special anchoring fixture for the prestressed steel wire has a simple structure and is simple and convenient to use and operate; secondly, the steel wire can be stretched and anchored in one step, the appearance size of the anchoring fixture is small, so that the anchoring fixture is convenient to construct and install; meanwhile, the materials can be saved, the cost can be reduced, and the anchoring fixture has remarkable economic benefits.

Description

Compressor wire self-anchoring type anchor clamp

Technical field

The special-purpose anchor clamp of the utility model compressor wire can be applicable to the high-strength compressor wire self-anchoring type anchor clamp of φ 3～φ 11.

Background technology

Uses at present the steel wire method of anchoring maximum be the use of steel wire heading, service efficiency is not high, steel wire heading effect is bad, must cutting steel wire, heading is processed again, has increased the artificial expense.Then ground tackle appearance and size is large to use on the market at present the ground tackle clamping, the waste material, and cost is high.

The utility model content

The utility model provides supporting with it ground tackle and anchor clamps, to put the structure anchor steel wire of a self-anchoring type, compressor wire self-anchoring type anchor clamp easy to install.

Solution of the present utility model is such: the utility model is applicable to the anchor clamp that diameter is φ 3～φ 11 steel wires, comprises the anchor ring of cylindrical internal taper hole, cooperates with the anchor ring internal taper hole, tapered intermediate plate, and described intermediate plate endoporus has thread; The outside diameter size A of described anchor ring is φ 26～φ 34 mm, and height dimension H is 28～36 mm, and bottom diameter B is φ 10～φ 13 mm, and taper hole diameter at butt end C is φ 16～φ 21 mm, and angle [alpha] is 12 °～16 °; The large footpath A1 of the major part of described intermediate plate is φ 16～φ 21 mm, and total length H1 is 25～33mm, angle [alpha] 1 be 12 ° 20 '～16 ° 20 ', screw thread M is M3 * 0.35～M11 * 1.

Technical scheme also comprises more specifically: described intermediate plate is provided with O type ring recess, groove width 2mm～4mm, and O type ring recess diameter B1 is φ 12.1～φ 17.2mm.

Further: the endoporus thread of described intermediate plate is fine thread.

Further: described intermediate plate is that the work clip sheet or three of two-piece type structure is levied the tool clamping piece of formula structure.

Advantage of the present utility model: 1, the special-purpose anchor clamp of stress wire, simple in structure, use easy and simple to handle.But 2 single tension anchoring steel wires, the little both constructabilities of the appearance and size of anchor clamp are installed, and can save material again, reduce cost, remarkable in economical benefits.

The specific embodiment

As shown in Figure 1, the utility model comprises intermediate plate and anchor ring, adopts to put and opens from anchor method anchoring prestress steel wire.Intermediate plate is the structure of outer cone internal thread, outside cone angle be 14 ° 20 ', internal thread is take wire gauge as the supporting closely-pitched triangle thread in large footpath, the large footpath of conehead is φ 16～φ 21mm, intermediate plate length 25～33mm, work clip sheet adopts two-piece type, and tool clamping piece adopts three-chip type; Anchor ring is cylindrical inner cone pore structure, anchor ring external diameter φ 26～34 is the 14 ° of large area of bed φ of taper hole 16～φ 21mm for the taper hole angle, utilize the frictional force of the pretensioned counter-force of steel wire and intermediate plate internal thread to be with in taper hole with intermediate plate, the intermediate plate internal thread is also along with putting Zhang Fanli constantly and compressor wire 1 engagement simultaneously, the intermediate plate outer cone then with the internal taper hole of anchor ring form wedging effect until with the pre-stretch-draw counter-force balance of steel wire, thereby the anchoring prestress steel wire.

As shown in Figure 2, the outside diameter size A of the described anchor ring 2 of the present embodiment is φ 26～φ 34 mm, and height dimension H is 28～36 mm, and bottom diameter B is φ 10～φ 13 mm, and taper hole diameter at butt end C is φ 16～φ 21 mm, and angle [alpha] is 14 °.

As shown in Figure 3, described intermediate plate 3 is φ 16～φ 21 mm for the large footpath A1 of major part, and total length H1 is 25～33mm, angle [alpha] 1 be 14 ° 20 ', and O type ring recess is arranged, groove width 2mm, diameter B1 are that φ 12.1～17.2mm screw thread M is M3 * 0.35～M11 * 1.

Shown in Fig. 4,5, when intermediate plate 3 adopted work clip sheet, work clip sheet adopted the two-piece type structure.

Shown in Fig. 6,7, when intermediate plate 3 adopted tool clamping piece, work clip sheet adopted the three-chip type structure.
