Embodiment Construction

[0021] Such as figure 1 As shown, the cable shaft structure of this high-rise building includes a shaft 1. There is a shaft cavity 8 penetrating up and down in the shaft 1. A notch 2 is opened in the shaft cavity 8 facing each floor, and the notch 2 is opened in the shaft cavity 8. On both sides of the inner wall of the notch 2, a connecting ear 11 is vertically arranged on both sides of the bottom surface of the notch 2, and a sealing plate 3 is elastically hinged between two adjacent connecting ears 11, and the sealing plate 3 is fixedly arranged with more than one side of the shaft cavity. The cable 5 is provided with a corresponding cable groove (not shown) on the inner wall of the shaft cavity 8 facing each cable 5. When the sealing plate 3 is reset, the cable 5 is buckled into the corresponding cable groove;

[0022] A layer of fireproof layer 4 is installed in the shaft cavity corresponding to each layer of building body. The width of the fireproof layer is smaller than...

Abstract

The invention discloses a high-rise building cable vertical shaft structure comprising a vertical shaft, a vertical penetrating vertical shaft cavity is in the vertical shaft, the vertical shaft cavity is internally provided with recesses facing floors, the recesses are set at two sides of an inner wall of the vertical shaft cavity, two sides of a bottom side of each recess are vertically providedwith a connection ear respectively, a sealing plate is elastically hinged between two adjacent connection ears, a side of the sealing plate facing the vertical shaft cavity is fixedly provided with more than one cable, an inner wall surface of the vertical shaft cavity facing each cable is provided with a corresponding cable slot, and the cable is buckled into the corresponding cable slot after the sealing plate is reset. The high-rise building cable vertical shaft structure has very good fireproof capability, a fire source can be quickly extinguished in the event of fire, each floor is blocked, and high-temperature smoke are prevented from spreading to entire floors, which is safer.

Description

technical field [0001] The invention relates to a shaft, in particular to a cable shaft structure for a high-rise building. 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 there is bigger potential safety ...
