Embedded part for cable bridge laying and construction method thereof

Abstract

The invention discloses an embedded part for cable bridge laying and a construction method thereof. The embedded part comprises a pre-buried bolt, a connecting sleeve and an extension bolt, wherein the pre-buried bolt is of a U-shaped structure, threads are machined at two ends of the U-shaped structure, each end part of the pre-buried bolt is matched with a connecting sleeve, the two ends of theconnecting sleeve are also provided with threads, through matching of internal threads and external threads, one end of the connecting sleeve is connected with the pre-buried bolt, and the other end of the connecting sleeve is connected with the threaded end of the extending bolt; the other end of the extension bolt is provided with a square end, and the square end of the extension bolt is connected and fastened with the connection sleeve at the later stage of installation; and the extension bolt is connected with the pre-buried bolt through the connecting sleeve when a cable support is installed, so that a cable support structure is fixed. According to the embedded part for cable bridge laying and the construction method thereof, the pre-buried bolt and the connecting sleeve are combinedto form a pre-buried part, the pre-buried part is integrally poured with the concrete, then the extension bolt is connected with the pre-buried bolt through the connecting sleeve, so that the fixing of the cable support structure is completed, and the construction is rapid and convenient.

Description

technical field [0001] The invention belongs to the field of cable laying engineering for transmission lines, and in particular relates to a pre-embedded part for laying cable bridges and a construction method thereof, aiming at meeting the needs of using bridges for cable laying in coastal areas under the marine environment. Background technique [0002] Embedded parts are structural parts that are pre-installed (buried) in concealed projects and poured together with other components. Embedded parts are used for lap joints when building superstructures to facilitate the installation and fixation of external engineering equipment foundations. [0003] The marine environment is the most corrosive natural environment. When cables are laid by bridges in coastal areas, cable brackets are often installed outside the concrete structure, and the cable brackets need to be fixed by embedded parts. Usually, the cable bracket can be fixed on the embedded parts by welding, but there may...

Problems solved by technology

Usually, the cable bracket can be fixed on the embedded part by welding, but there may be safety hazards in the field welding operation in the marine environment

Or use pre-embedded bolts for bolt connection, but the pre-embedded bolts need to open holes on the formwork for positioning, resulting in waste of formwork

[0004] Therefore, it is necessary to improve the existing embedded parts technology to solve the technical and economical deficiencies
