Abstract

A simultaneous follow-up anchorage clip relates to the clip of a prestressing clip type anchorage used for a construction, which is two-piece type, and is characterized in that the a groove is arranged on a matching surface of the two clips; a ridge (1) is arranged on another matching surface; the groove and the ridge are in a clearance fit; the groove and the ridge on the clips of the utility model limit an axial displacement between the clips to make the clip follow up simultaneously so as to strengthen an axial acting force among the clips, and guarantee an even stress of the clips; thereby an anchoring dependability is improved without adding a purpose-built retaining ring. If a retaining ring groove is arranged on a tapered surface of the clip and a steel retaining ring or an O type rubber ring is arranged in the retaining ring groove, the retaining ring is controlled the retaining ring groove of the clip and an anchor plate axially and radially, and not easy to release, which further strengthens the axial acting force among the clips, and improves the anchoring dependability.

Description

A kind of anchor clipper of follow-up simultaneously

Technical field

The utility model relates to a kind of building operations prestressed anchor assembly, particularly a kind of anchor clipper of follow-up simultaneously.

Background technology

The prestressed anchor of consumption maximum is the intermediate plate anchor in the market, the fine or not key of intermediate plate anchor quality depends on the design of intermediate plate, and in the existing working strand tapered anchorage, intermediate plate is generally three-chip type or two-piece type, afterbody has one to place the groove that constraint is enclosed, and the constraint circle is generally O type rubber ring.Because groove structure and constraint circle intensity are limit, intermediate plate is not enough in the mutual restraint forces of axis direction, this often causes in stretching process the intermediate plate follow-up uneven, and each intermediate plate is to the chucking power inequality of presstressed reinforcing steel and the pinch off presstressed reinforcing steel makes anchoring efficient can not get guaranteeing.

Technology contents

The technical problems to be solved in the utility model is: existing intermediate plate is not enough in the mutual restraint forces of axis direction, and do not locate between each sheet of intermediate plate, cause in stretching process the intermediate plate follow-up uneven and circumferentially between skewness, the problem that makes anchoring efficient can not get guaranteeing provides a kind of anchor clipper that can follow up simultaneously in stretching process.

The technical scheme that solves its above-mentioned technical problem is: a kind of simultaneously the follow-up anchor clipper, two-piece type is characterized in that: on the mutual bonding surfaces of two intermediate plates wherein a slice open a groove, another sheet is opened a tongue, is matched in clearance between the tongue and groove.

As another kind of pattern of the present utility model is to also have a constraint ring recess on the conical surface of this intermediate plate, and the constraint circle in the constraint ring recess is one the steel elastic ring or the O type rubber ring of opening to be arranged.

Owing to adopt said structure, a kind of anchor clipper of follow-up simultaneously of the utility model is compared with existing intermediate plate, has following beneficial effect:

1, the tongue and groove on the utility model intermediate plate has retrained the axial displacement between each sheet intermediate plate, each sheet intermediate plate is followed up simultaneously, strengthened axial active force between each sheet intermediate plate, guaranteed that each sheet intermediate plate is stressed evenly, need not increase special constraint circle, just can improve the reliability of anchoring.

2, if on the conical surface of intermediate plate, increase by a constraint ring recess again, the constraint circle of constraint in the ring recess is one the steel elastic ring or the O type rubber ring of opening to be arranged, this constraint is enclosed from the control and the difficult disengaging that axially and radially all have been subjected to intermediate plate constraint ring recess and anchor slab, retrain the axial displacement between each sheet intermediate plate, each sheet intermediate plate is followed up simultaneously, strengthened axial active force between each sheet intermediate plate, guaranteed that each sheet intermediate plate is stressed evenly, further improved the reliability of anchoring.

Fig. 2: the utility model embodiment two described a kind of anchor clipper structural representations of follow-up simultaneously;

The A-A half sectional view of Fig. 3: Fig. 1 and Fig. 2.

The specific embodiment:

Below, a kind of technical characterictic of the anchor clipper of follow-up simultaneously to the utility model is further described in conjunction with the accompanying drawings and embodiments.

Embodiment one:

A kind of simultaneously the follow-up anchor clipper, two-piece type, on the mutual bonding surfaces of two intermediate plates wherein a slice open a groove, another sheet is opened a tongue (1), be matched in clearance (referring to Fig. 1, Fig. 3) between the tongue and groove, the afterbody of described intermediate plate has a constraint ring recess, is placed with a constraint circle in the groove.

Embodiment two:

A kind of simultaneously the follow-up anchor clipper, two-piece type, on the mutual bonding surfaces of two intermediate plates wherein a slice open a groove, another sheet is opened a tongue (1), is matched in clearance between the tongue and groove; Also have a constraint ring recess on the conical surface of this intermediate plate (2), the constraint circle in the constraint ring recess is one the steel elastic ring or the O type rubber ring (3) (referring to Fig. 2, Fig. 3) of opening to be arranged.

Claims

1, a kind of simultaneously the follow-up anchor clipper, two-piece type is characterized in that: on the mutual bonding surfaces of two intermediate plates wherein a slice open a groove, another sheet is opened a tongue (1), is matched in clearance between the tongue and groove.

2, a kind of anchor clipper of follow-up simultaneously according to claim 1 is characterized in that: also have a constraint ring recess on the conical surface of this intermediate plate (2), the constraint circle in the constraint ring recess is one the steel elastic ring or the O type rubber ring (3) of opening to be arranged.
