Abstract

The invention discloses a cable shaft and cables applied into the cable shaft. The cable shaft comprises a shaft body. The shaft body comprises a base, two sealed supporting plates and a shaft box. Ashaft cavity is formed in the middle of the shaft box. More than one cable clamp opening is arranged on the two side faces of the shaft cavity. An arc clamping cavity is arranged in each cable clamp opening. An arc limiting opening is arranged at the open end of each clamping cavity. One cable is mounted in each arc clamping cavity and is limited through the corresponding arc limiting opening, andall the cables are perpendicular to the horizontal plane. An open groove is formed in the position, right facing each clamping cavity, of the outer side face of the shaft box. A heat radiation grooveis formed in the bottom face of each open groove. The heat radiation grooves and the open grooves are arranged in a manner of extending in the height direction of the shaft body. After the cables arearranged in the cable shaft, good heat radiation performance can be guaranteed, meanwhile, extremely good smoke diffusion resistance and fireproofness are achieved, and the overall safety of a building can be effectively increased.

Description

technical field [0001] The invention relates to the field of building cable laying, in particular to a cable shaft and cables used inside. Background technique [0002] There are often various vertical shafts in buildings, such as stairwells, elevator shafts, cable shafts, garbage shafts, ventilation shafts and smoke exhaust shafts, etc., running through several floors or even all floors. With the increasing number of high-rise buildings, cable shaft fires are sometimes occur. The wires and cables in the cable shaft are used all the year round and are prone to aging. If the daily maintenance is not timely at this time, once the insulation sheet is damaged, it is prone to short circuit and fire. Once a fire breaks out, a large amount of heat carried by the fire smoke quickly spreads to the entire building through the cable shaft. Wherever the high-temperature smoke rushes, the combustible materials will burn, accelerating the spread of the fire. Therefore, the structure of ...
