Embodiment

[0027] The project has six floors in the basement and 52 floors above the ground. The substation and power distribution room are located on the first floor of the basement. The power cables of this project are distributed to the distribution boxes on each floor through the laying of electric wells. The cables are heavy and too long. In order to ensure the construction quality, the construction method of laying cables vertically in super high-rise buildings is adopted.

[0028] (1) Install a cable reducer every 3 floors on the building structure 6 close to the cable bridge along the cable lowering direction. Described cable speed reducer comprises the channel steel 3 that is arranged vertically, and described channel steel is fixed on the building structure, between the left flange plate and the right flange plate of described channel steel 3 The upper part and the lower part are respectively connected with a fixed pulley 1 by bolts arranged in the horizontal direction, and a s...

Abstract

The invention discloses a construction method for vertically laying super-high-rise building cable. The construction method includes the steps: (1) mounting a cable reducer on a building structure close to a cable bridge every preset distance along the lowering direction of the cable; (2) conveying the coiled cable to the highest layer of a building by equipment and mounting the coiled cable on acable pay-off rack with an emergency brake; (3) lowering a cable head in a pulling manner, and laying the cable sequentially bypassing all the cable reducers from top to bottom; (4) detaching the cable reducers from the building structure from top to bottom, moving the cable reducers into the cable bridge and temporarily fixing the cable reducers; (5) detaching two fixed pulleys of each cable reducer, moving the cable into the cable bridge, fixing the cable and finishing laying the cable. By the method, the super-high-rise building cable can be safely and rapidly vertically laid and constructed in a quality and quantity guaranteed manner.

Description

technical field [0001] The invention relates to a construction method for vertical laying of cables, in particular to a construction method for vertical laying of cables in super high-rise buildings. Background technique [0002] At present, in the electromechanical construction project, the vertical laying of super high-rise building cables is a very critical construction link. How to complete the super high-rise building cable laying construction safely, quickly, and with quality and quantity will directly affect the quality level and construction progress of the entire electromechanical project. [0003] The Chinese patent with the application number CN201720140132.3 discloses "a composite cable tray bracket for vertical laying of cables", which is composed of a bracket body, which includes a horizontally arranged main beam, and the bottom of the main beam is welded with Auxiliary braces, the front end and rear end of the main girder are provided with installation holes a...
