Buckling stainless steel protective sleeve, multi-section spliced stainless steel protective sleeve and manufacturing method

Abstract

The invention discloses a buckling stainless steel protective sleeve. Before buckling, the stainless steel protective sleeve is a cambered protective sleeve with an approximately circular cross section and two connecting ends; the edge of a long edge of an oblong plate for forming the cambered protective sleeve has an inverted U-shaped structure, and the edge of the other long edge has an I-shaped structure; and in a buckled state, the oblong plate for forming the cambered protective sleeve is buckled through the inverted U-shaped structure and the I-shaped structure at the edges of the two long edges and are flattened to form a fully circular protective sleeve so as to tightly wrap a rope body. Upper and lower adjacent sections of stainless steel protective sleeves of a multi-section spliced buckling stainless steel protective sleeve formed by splicing more than two sections of buckling stainless steel protective sleeves are spliced integrally in a lapping connection mode or a bayonet structure connection mode. The buckling stainless steel protective sleeve can adapt to the protection of the rope with a larger deviation rope diameter, so that the mounting difficulty is reduced, and the protective sleeve is simple, practical and attractive. The multi-section spliced stainless steel protective sleeve which is spliced has a simple, convenient and time-saving manufacturing and mounting process.

Description

technical field [0001] The invention relates to a new product for protecting bridge cable PE-a stainless steel sheath tube and a manufacturing method thereof. Background technique [0002] The stainless steel sheath tube is a new type of product used to protect the PE surface of the bridge cable in bridge engineering to avoid light aging and damage by people or other factors; there are two main types of existing stainless steel sheath tubes: one is two semicircular welded multi-section The spliced ​​sheath tube, the other is a full-circle inverted V-shaped snap-fit ​​connection method with multiple spliced ​​sheath tubes. Their connection and splicing methods have shortcomings: [0003] (1) Each section of the two semi-circular welded multi-section spliced ​​sheath tubes is welded to form a sheath tube 5, and the two adjacent upper and lower sheath tubes are also welded to form a single piece (see Figure 7-1~Figure 7-2 ), the shortcomings of this connection method are: [...

AI Technical Summary

Problems solved by technology

[0010] The object of the present invention is to provide a snap-fit ​​stainless steel sheath pipe, a multi-section spliced ​​stainless steel sheath pipe and its production and installation method. The protection of the large deviation cable diameter, the whole installation process does not require welding and grinding, avoiding the damage to the sheath tube and the cable body caused by the welding process, so as to solve the problem of the existing two-half-circle welding type and full-circle inverted V-shaped buckle connection method with multiple sections The above-mentioned technical problems existing in splicing stainless steel sheath pipes
