Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0020] Such as Figure 3 to Figure 5 The sheath element 4 shown is a half-tube body with a tenon pin 2 and a tenon groove 3 respectively at the two joints, and a raised spiral rib 1 is provided on the outer surface of the half-tube body; as figure 1 , figure 2 The multiple sheath elements 4 shown are connected and installed on the stay cables, as follows:

[0021] A. According to the length of the cable, connect the ends of the sheath elements 4 to each other, and weld them one by one to form a long half-pipe. When welding, connect the ends of the spiral ribs on the outer sides of the two sheath elements 4. head butt; weld another long half pipe according to the above method;

[0022] B. Wrap the two long half-pipes with the cable, insert the tenon pin 2 of one of them into the tenon groove 3 of the other to form a circular tube, enclose the cable i...

Abstract

The invention discloses a connection method of an inhaul cable protecting bush and relates to the technical field of architectural engineering. Protecting elements are adopted, and each protecting element is a half-tube body which is provided with a draw-bore pin and a mortise, wherein the draw-bore pin and the mortise are arranged on two joint parts. Connection is carried out according to the following steps: A, according to the length requirement of an inhaul cable, the protecting bush elements are welded to be a long half tube one by one; and B, the draw-bore pin of one long half tube is inserted into the mortise of the other long half tube to be fastened on the exterior of the inhaul cable. Protruded spiral rib bars are arranged on the outer side faces of the half-tube bodies. The method is simple and easy to practice, prevents the inhaul cable protecting bush and an inhaul cable steel wire from being damaged and improves working efficiency.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a connection method for protective sleeves of construction cables. Background technique [0002] With the rapid development of long-span bridge construction, cable-stayed bridges and suspension bridges are more and more widely used. Steel wire cables are the key components used in cable-stayed bridges and suspension bridges. Then insert the high-density polyethylene sheath, the cable sheath plays the anti-corrosion effect of the steel wire rope, the installation of the cable sheath at the present stage must first cover the round tube sheath section by section before the two ends of the cable are fixed. The cable is then welded piece by piece to the desired length. In this construction method, the inner wall of the sheath may be damaged by the steel wire of the cable during the cable threading process; and the welded section needs to be planed before the sheath i...
