Embodiment Construction

[0021] refer to figure 1 , the super high-rise building vertical cable laying method, comprises the following steps:

[0022] (1) Conduct necessary on-site measurements on the site, and install cable trays along the direction of the cables.

[0023] Among them, in the field measurement of this step, it includes compiling the cable table according to the drawing, mastering the cable specification, length, start and end positions, and all the cable bridges (brackets) along the direction of the cable 5 should be installed.

[0024] (2) Determine the number of damping retarders.

[0025] Wherein, the subsection load-bearing capacity of the damping retarder is calculated according to the total height of the vertical section and the gravity of the cable 5 with the largest section, so as to determine the number of devices.

[0026] Among them, refer to figure 2 , 3 , 4, the damping buffer includes a bracket 4 and an upper guide wheel 1, an intermediate guide wheel 3 and a lower...

Abstract

The invention discloses a method for laying vertical cables for extra-high buildings. A whole roll of cables is lifted to a high-rise floor, the cables are laid from top to bottom by using high-level potential, and the gravity acceleration caused by a put-down process is overcome by using damp retarders which are arranged in sections so that the effect is safe and rapid, and the insulation quality of the cables is sound. The time spent for putting each cable from the highest point to an underground is 7-8 minutes according to comprehensive calculation, and the put-down speed of the cable is stable with desired control, and only 20 operation staffs are needed to lay the vertical cables in more than 60 layers of vertical cable wells so as to save the labor forces. The invention solves the technical problem of laying the vertical cables of the extra-high buildings, thereby having the advantages of safety, rapidness, labor-saving, material-saving, obvious economic effect and wide promotion use value on the laying of the vertical cables of high buildings and extra-high buildings, and simultaneously ensuring the sound insulation quality of the cables.

Description

technical field [0001] The invention relates to the construction technical field of a super high-rise building vertical cable laying method, in particular to a super high-rise building vertical cable laying method. Background technique [0002] At present, with the continuous development of urban buildings towards super high-rise buildings, mechanical and electrical installation projects will inevitably encounter various problems brought about by super high-rise buildings. The vertical laying of super high-rise cables is one of the more prominent problems. There are two common methods for laying vertical cables in high-rise buildings. One is to distribute many people along the laying path to pull together, which is still feasible when the floor is not high (generally less than 10 floors) and the cable cross-section is not large; the other is to encounter high floors (20 floors) -30 floors) use the electric winch steel cable to pull upwards. Both methods have their own dis...
