Embodiment Construction

[0018] Please refer to the attached figure 1 to attach Figure 4 As shown, the present invention is a steel strand end anchorage structure and its anchoring method, which is composed of a steel strand 1, an anchor plate 2, and a clip 3.

[0019] Wherein, the steel strand 1 is specifically a steel strand 1 whose end portion of a prestressed composite beam 4 is exposed. The clip 3 is clamped on the steel strand 1, and the clip 3 can tighten the steel strand 1 so that the anchor plate 2 will not be displaced.

[0020] The anchor plate 2 can be in various shapes such as circular or square, and a circular hole 21 is arranged on it. The diameter of the circular hole 21 is larger than that of the steel strand, so that the steel strand 1 can pass through the circular hole 21 of the anchor plate 2 . The area of ​​the anchor plate 2 is more than four times the cross section of the steel strand 1, thereby enhancing the anchoring strength of the anchoring structure.

[0021] One end ...

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 [0001] The invention relates to an anchoring structure and an anchoring method for a steel strand end applied to a prefabricated assembly structure, and belongs to the technical field of construction engineering. Background technique [0002] According to the requirements of the current "Code for Design of Concrete Structures", the longitudinal reinforcement of the beam must be effectively anchored in the column, and the anchorage length has strict requirements. In general, the anchorage length for the longitudinal reinforced steel bar of the beam to extend into the column is relatively long, especially in areas with high earthquake resistance level, the anchorage length is very long, and the strength of the steel strand is stronger than that of the ordinary stressed steel bar. High, according to the requirements of the above specifications, its anchorage length is often 2 to 3 times that of ordinary steel bars. [0003] Therefore, for prestressed composite ...
