Abstract

The utility model provides an anchorage clamp which can tightly clamp prestressed stranded wires in different classes; wherein the clamp is a cone and the tapers of conical surfaces are the same. The utility model is characterized in that the reversed cone length L1 of the internal hole at the small tip of the clamp is 10-14mm and the reversed cone taper * Gamma is 1/20-1/25.

Description

Anchor clipper

Technical field

The utility model belongs to the prestressing force class, and specifically the presstressed reinforcing steel in the building unit is clamped to the intermediate plate on the ground tackle anchor ring.

Background technology

Existing building operations is with in the strand tapered anchorage, work clip sheet is generally two four open types of truncated cone-shaped, the big 4mm that has an appointment that holds is cylindrical, itself and steel strand contact surface are pawl shape screw thread, and intermediate plate small end endoporus back taper tapering is 1/17, adopt rubber ring with one pair of circle together, in long-term use, find that this intermediate plate has the following disadvantages: 1, intermediate plate small end endoporus back taper tapering is excessive, causes stress to concentrate, and makes steel strand form easily and cuts off; 2, big end does not contact with the anchor slab endoporus for cylindrical its external surface, and is less to the clamping action that steel strand played; 3, intermediate plate splits at the elastic groove place sometimes.

Summary of the invention

The purpose of this utility model is to improve existing intermediate plate above shortcomings part, but the anchor clipper of other prestress wire of the various level of a kind of firm grip is provided.

The purpose of this utility model can reach by following measure:

A kind of anchor clipper, described intermediate plate are conical, and its male cone (strobilus masculinus) tapering unanimity is characterized in that: intermediate plate small end endoporus back taper length L 1 is 10-14mm, back taper tapering

Be 1/20 to 1/25.

The purpose of this utility model can also reach by following measure:

Described intermediate plate is whole four open types, and the big end of intermediate plate has the long elastic groove 1 of 12-15mm that is.

The utility model has following advantage compared to existing technology:

1, makes intermediate plate male cone (strobilus masculinus) tapering unanimity, increase the chucking power of the big end of intermediate plate, make that steel strand are stressed in intermediate plate to be tending towards even steel strand;

2, reset small end endoporus back taper, length, make small end, guarantee that steel strand are not cut off in construction, effectively reduce construction cost the corresponding minimizing of steel strand chucking power;

3, reset the big end elastic groove of intermediate plate length, guarantee that intermediate plate can not split, and has eliminated the potential safety hazard in the construction in the pre-stress construction follow-up.

Description of drawings

Fig. 1 is the utility model schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, this anchor clipper is the taper shape of external taper unanimity, whole two four open types, and the long L1 of intermediate plate small end endoporus back taper is 10-14mm, the back taper tapering Be 1/20 to 1/25; The big end of intermediate plate has the long 12-15mm elastic groove 1 that is.

Claims

1, a kind of anchor clipper, described intermediate plate are conical, and its male cone (strobilus masculinus) tapering unanimity is characterized in that: intermediate plate small end endoporus back taper length L 1 is 10-14mm, back taper tapering Be 1/20 to 1/25.

2, anchor clipper as claimed in claim 1 is characterized in that: described intermediate plate is whole four open types, and the big end of intermediate plate has the long elastic groove of 12-15mm (1) that is.
