Embodiment Construction

[0013] An anchor pad such as figure 1 Shown: The anchor plate is a round tower-shaped structure with a hollow interior and 2-4 steps in shape. The steps between each step and the tower body are arc-shaped, R=15-50mm, and the tower foot is for sinking anchors. The cylindrical part of the plate, the taper of the hollow tapered hole γ = 2 ~ 5 °, the thickness of the bearing plate δ 1 30-70mm, tower wall thickness δ 2 7 ~ 15mm, step thickness δ 3 7 ~ 12mm, the overall casting shape.

Abstract

An anchor shoe is a hollow (2-4)-step circular tower structure with a bearing plate. It has a central conic through hole and a recessed circle for holding anchor plate in it. Said anchor shoe is madeintegrally up by casting. Its advantages are small size, uniform and low stress, light weight, less damage to anchor cable and low cost.

Description

1. Technical field: [0001] The invention relates to a prestressed anchor component, in particular to an anchor plate. 2. Background technology: [0002] Existing anchor pads such as figure 2 As shown, the shape is generally a hollow tower shape, which is composed of a square platform, a round platform and four reinforcing ribs, one of which has a grouting hole; it is integrally cast. The disadvantages of this structure are: firstly, the area of ​​the four-sided platform is too large, the concrete pouring between the lower two ribs is not easy to be compacted, and the number of steel bars on the surface of the anchorage area is too large; secondly, the stress under the concrete anchorage is relatively large, and the stress under the rib tends to Third, inside the anchor plate, the angle between the steel strands of the outer ring and the axis is relatively large, which increases the probability of the steel strands being cut during the tensioning process; fourth, the externa...
