The invention relates to a connecting structure of a suspension bridge cable clamp and a main cable and a construction technology. The cable comprises a main cable, a sling, an anchor head and a lug plate, the sling and the lug plate are connected to the two ends of the anchor head respectively, the main cable is a finished cable with a PE sheath, the cable further comprises a zinc gasket and two connected clamping plates, the clamping plates are rotationally connected to the lug plate, each clamping plate comprises a containing cavity with the cross section being in a semicircular arc shape, and the containing cavities are arranged in the containing cavities. The cross section of the zinc gasket is of a semi-arc structure, the outer arc face of the zinc gasket is attached to the inner arc face of the containing cavity, the main cable comprises the surface of the main cable after PE is stripped, and the surface of the main cable after PE is stripped is attached to the inner arc face of the zinc gasket. By arranging the zinc gasket, the defects that PE is directly clamped by the cable clamp, and the tensile strength of the PE material is limited are overcome, and large anti-sliding force can be provided by utilizing friction force between the clamping plate and the zinc gasket and friction force between the zinc gasket and the parallel galvanized steel wires in the main cable, so that the vertical bearing capacity of the sling is fully exerted.
本发明涉及一种悬索桥索夹与主缆的连接结构及施工工艺。本发明包括主缆、吊索、锚头和耳板，所述吊索、耳板分别连接于锚头两端，所述主缆为带PE护套的成品缆索，还包括锌垫圈和两块相连的夹板，所述夹板转动连接于耳板，所述夹板包括横截面为半圆弧形状的容置腔，所述锌垫圈为横截面为半圆弧形状的结构，所述锌垫圈的外弧面与容置腔的内弧面相贴合，所述主缆包括剥除PE后的主缆表面，所述剥除PE后的主缆表面与锌垫圈的内弧面相贴合。通过设置锌垫圈，避免了索夹直接夹持PE，而PE材料抗拉强度有限的弊端，利用夹板与锌垫圈、锌垫圈与主缆内部的平行镀锌钢丝之间的摩擦力，可提供较大的抗滑力，从而使得充分发挥吊索竖向承载力。
