Abstract
An anchor clip relates to a prestressing anchor clip for the construction. The anchor clip has two outer conical degrees, which are provided with a concave slot on the periphery. The anchor clip is characterized in that an outer conical degree (a1) between a big end of the clip and an upper part of the concave slot is bigger than an outer conical degree(a2) between a small end of the clip and a lower part of the concave slot; and the difference is 10-20degrees. The anchor clip assures a better self-anchor performance at an early clamping stage during the anchor fixation process, relatively reduces the positive pressure on the steel stranded wire at a late clamping stage, and improves the anchor fixation performance of the anchor with the processing and manufacturing convenience and high efficiency.
Description
Technical field:
The utility model relates to a kind of intermediate plate, a kind of building operations pre-stress anchor clipper.
Background technology:
The prestressed anchor of consumption maximum is the intermediate plate anchor on the market now, the fine or not key of intermediate plate anchor quality depends on the design of intermediate plate, general intermediate plate outer rim is conical, perhaps be truncated cone-shaped more than the groove, be conical below the groove, its outer cone is same angle (referring to Fig. 2, Fig. 3, among Fig. 2: outer cone angle a
3=a
4), rely on the wedge type principle to clamp steel strand, in clamping process, because that intermediate plate outer cone angle equally reaches friction factor is identical, therefore the normal pressure on the steel strand is linear increase with the pulling force increase of steel strand, normal pressure is crossed the efficiency of anchorage that senior general reduces ground tackle, and for this reason, the applicant is existing intermediate plate above shortcomings part, the outer cone angle of once having applied for a kind of anchor clipper in 2000 is that two or more is (referring to Fig. 4, among the figure: outer cone angle a
6＞a
7), intermediate plate major part outer cone angle is greater than " anchor clipper " (patent No.: 0251326.6) of intermediate plate microcephaly outer cone angle, improved the stress of intermediate plate and prestress wire, improve the efficiency of anchorage of ground tackle assembly, but in implementation process, find the processing more complicated of this kind anchor clipper, work efficiency is low.
Technology contents
The technical problems to be solved in the utility model is: existing two kinds of existing processing more complicated of tapering intermediate plate, the problem that work efficiency is low, a kind of stress that can improve intermediate plate and prestress wire is provided, improve the efficiency of anchorage of ground tackle assembly, the outer cone angle of convenient processing has the intermediate plate of two kinds of taperings again.
The technical scheme that solves its above-mentioned technical problem is: a kind of anchor clipper, described anchor clipper outer cone angle is two kinds, its outer rim has a groove, it is characterized in that: the big end of described intermediate plate, groove with the outer cone angle of upper part greater than intermediate plate small end, partly outer cone angle below the groove.
The big end of described intermediate plate, groove are generally 10 '～20 ° with outer cone angle and intermediate plate small end, the difference of the outer cone angle angle of part below the groove of upper part.
Intermediate plate is in clamping the anchoring process, clamping the frictional force that requires steel strand and intermediate plate endoporus early stage frictional force and the horizontal component sum of anchor slab internal taper hole, the automatic clamping of intermediate plate ability steel strand like this to the intermediate plate normal pressure greater than outer cone with the anchor slab internal taper hole of intermediate plate; Through calculating, clamping early stage, intermediate plate outer cone angle is less for well; And clamping the later stage in order to reduce the normal pressure on the steel strand, intermediate plate outer cone angle is better.The anchor clipper outer cone of the utility model is designed to two kinds of angles; The following outer cone angle partly of intermediate plate small end, groove is less than the big end of intermediate plate, the groove outer cone angle with upper part, guaranteeing like this has preferably from the anchor performance in clamping in the intermediate plate anchoring process early stage, in the clamping later stage normal pressure on the steel strand is reduced relatively simultaneously, improved the anchoring property of ground tackle.Because the variation of tapering is the boundary with the groove, thereby convenient processing and manufacture, efficient height.
Below, the architectural feature to the anchor clipper of the utility model is described further in conjunction with the accompanying drawings and embodiments.
Description of drawings:
Fig. 1: the utility model anchor clipper structural representation;
Fig. 2～Fig. 3: existing a kind of tapering anchor clipper structural representation;
Fig. 4: existing two kinds of tapering anchor clipper structural representations.
The specific embodiment:
Embodiment
A kind of anchor clipper, its outer rim has a groove, and the big end of described intermediate plate, groove are with the outer cone angle (a of upper part
1) greater than intermediate plate small end, partly outer cone angle (a below the groove
2).
The big end of described intermediate plate, groove are with the outer cone angle (a of upper part
1) with the following outer cone angle (a partly of intermediate plate small end, groove
2) difference of angle is 10 '～20 °.
Claims (2)
1, a kind of anchor clipper, described anchor clipper outer cone angle is two kinds, its outer rim has a groove, it is characterized in that: the big end of described intermediate plate, groove are with the outer cone angle (a of upper part
1) greater than intermediate plate small end, partly outer cone angle (a below the groove
2).
2, anchor clipper as claimed in claim 1 is characterized in that: the big end of described intermediate plate, groove are with the outer cone angle (a of upper part
1) with the following outer cone angle (a partly of intermediate plate small end, groove
2) difference of angle is 10 '～20 °.
