Abstract
The invention relates to an anchoring structure for an end part of a steel strand. The anchoring structure comprises a steel strand, an anchor plate and a clamp, wherein the clamp is clamped on the steel strand; the anchor plate is provided with a round hole through which the steel strand penetrate; a steel strand upset head is formed at one end of the steel strand; and the anchor plate is butted and connected between the steel strand upset head and the clamp. According to the invention, the anchoring length of a longitudinal steel strand at the lower part of a prestress superposed beam in a column is shortened by 40%, thus, not only can the steel strand be effectively saved, but also the problems that the anchoring length of the steel strand is too large in the column to anchor are effectively solved, in addition, the problem of reinforcing bar congestion at a beam-column joint position is avoided, and thus, the effect of achieving three purposes by one action is achieved. In addition, an anchoring method is low in price, simple to construct and easy for construction operation, and has a favorable popularization value.
Description
Technical field
The present invention relates to a kind of steel strand end anchorage structure and anchoring process thereof that is applied to prefabricated package assembly, belong to construction engineering technical field.
Background technology
According to the requirement of existing " Code for design of concrete structures ", the longitudinal stress reinforcing bar of beam must effectively be anchored in the post, and its anchorage length has strict requirement.The anchorage length that the longitudinal stress reinforcing bar of ordinary circumstance underbeam must stretch in the post is longer; Particularly in the higher area of antidetonation grade; This anchorage length is very long; And steel strand are higher because of the more common steel bar stress intensity of its intensity, and according to above-mentioned code requirement, it is 2～3 times of plain bars that its anchorage length tends to.
Therefore, for using steel strand, must properly settle the anchorage length problem of steel strand in post, otherwise will have a strong impact on construction quality and structural safety as for the prestressing force superposed beam of longitudinal stress reinforcing bar.
Therefore, for solving the problems of the technologies described above, necessary a kind of have structure improved steel strand end anchorage structure and anchoring process thereof be provided, to overcome said defective of the prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of steel strand end anchorage structure simple in structure, it can effectively shorten prestressing force superposed beam longitudinal stress reinforcing bar is the anchorage lengths of steel strand in post.
Another object of the present invention is to provide a kind of anchoring process of steel strand end anchorage structure, be specifically related to a kind of prestressing force superposed beam longitudinal stress reinforcing bar when being steel strand, the anchoring process of prestressing force superposed beam longitudinal stress reinforcing bar in post.
For realizing above-mentioned purpose, the technical scheme that the present invention takes is: a kind of steel strand end anchorage structure, and it comprises steel strand, anchor slab and clip; Wherein, said clip is held on the steel strand; Said anchor slab is provided with a circular hole, and said steel strand pass the circular hole of said anchor slab; Said steel strand one end forms a steel strand heading; Said anchor slab is connected between steel strand heading and the clip.
Steel strand end anchorage structure of the present invention further is set to: said anchor slab is for circular or square, and other shape.
Steel strand end anchorage structure of the present invention further is set to: the somewhat larger in diameter of said circular hole is in the diameter of steel strand.
Steel strand end anchorage structure of the present invention also can be set to: the area of said anchor slab is more than 4 times of steel strand cross section.
For realizing above-mentioned another purpose, the technical scheme that the present invention takes is: a kind of anchoring process of steel strand end anchorage structure, and it comprises following processing step: 1), a prefabricated prestressing force superposed beam exposes steel strand in its end; 2), on steel strand, penetrate anchor slab, clip respectively, use ordinary steel twisted wire button head machine will expose the end heading of steel strand then and form the steel strand heading, anchor slab is located between steel strand heading and the clip; 3), the prestressing force superposed beam is installed in cylinder top, anchor slab is moved near the steel strand heading, it is in place with the anchor slab fixed-site to lock clip then.
Compared with prior art; The present invention has following beneficial effect: the present invention will make the anchorage length of the vertical steel strand in prestressing force superposed beam bottom in post shorten 40%, like this, can not only effectively practice thrift steel strand; It is oversize in post internal cause anchorage length to efficiently solve steel strand simultaneously; Be difficult to the problem of anchoring, and avoided at the bean column node position reinforcing bar block up problem, killing three birds with one stone thus.This anchoring process is cheap in addition, and construction is simple, is easy to constructing operation, has good universal value.

The specific embodiment
See also shown in Figure of description 1 to the accompanying drawing 4, the present invention is a kind of steel strand end anchorage structure and anchoring process thereof, and it is made up of several parts such as steel strand 1, anchor slab 2 and clips 3.
Wherein, the steel strand 1 that expose of said steel strand 1 end that is specially a prestressing force superposed beam 4.Said clip 3 is held on the steel strand 1, and this clip 3 can step up steel strand 1, and anchor slab 2 can be shifted.
Said anchor slab 2 can which is provided with a circular hole 21 for circle or multiple shape such as square.The diameter of said circular hole 21 is greater than the diameter of steel strand, thereby makes steel strand 1 can pass the circular hole 21 of said anchor slab 2.The area of said anchor slab 2 is more than 4 times of steel strand 1 cross section, thereby strengthens the anchoring strength of this anchor structure.
Said steel strand 1 one ends form a steel strand heading 11 through ordinary steel twisted wire button head machine.Said anchor slab 2 is connected between steel strand heading 11 and the clip 3.
The anchoring process of steel strand end anchorage structure of the present invention is following: 1), a prefabricated prestressing force superposed beam 4 exposes steel strand 1 in its end; 2), on steel strand 1, penetrate anchor slab 2, clip 3 respectively, use ordinary steel twisted wire button head machine will expose the end heading of steel strand 1 then and form steel strand heading 11, anchor slab 2 is located between steel strand heading 11 and the clip 3; 3), prestressing force superposed beam 4 is installed in a cylinder 5 tops, anchor slab 2 is moved near the steel strand heading 11, locking clip 3 is in place with anchor slab 2 fixed-site.
The above specific embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
