Fireproof fabricated construction system for super high-rise electrical vertical shaft

Abstract

The invention discloses a fireproof fabricated construction system for a super high-rise electrical vertical shaft. The fireproof fabricated construction system comprises a masonry brick wall, bridge frames, a shear wall and fireproof steel plates. The system has the beneficial effects that the fireproof steel plates and brackets are prefabricated in a factory, so that the work of field measurement and cutting is reduced, a large amount of labor is saved under the condition of labor shortage, the construction time is shortened, and the construction progress is accelerated; the fireproof steel plates are made of 1.5 mm steel plates and are high in strength, the steel plates are supported by the assembly type brackets at the bottom of the beams, and the fireproof plates cannot deform under the conditions that a vertical shaft opening is deep, gaps are large and more fire-retardant bags and fireproof daub need to be packaged so that the fireproof effect can be well achieved, and flames are prevented from spreading to adjacent floors through the opening; and a smoke detector adsorbed on the fireproof steel plate can quickly and timely detect the content of various abnormal smoke and report the position at the first time, so that conditions are created for related personnel to extinguish fire at the first time before open fire is generated on site or the open fire is not spread.

Description

technical field [0001] The invention relates to a fireproof assembled construction system for an electrical shaft, in particular to a fireproof assembled construction system for a super high-rise electrical shaft, which belongs to the technical field of electrical construction. Background technique [0002] In traditional shaft fireproofing and sealing construction, inorganic fireproof partitions are often used as fireproof boards. According to the installation conditions of the on-site bridge frame and the size of the gap at the shaft opening, on-site measurement, on-site cutting, and on-site assembly. This installation method requires the use of a variety of electric tools, which increases the risk of electricity use, and consumes more time. In the case of tight construction schedules, the construction period will be delayed. [0003] In super high-rise buildings, the height of the structural beam at the bottom of the shaft opening will be greater, and the opening to be se...

Problems solved by technology

In the case of good fire prevention and sealing, although the fire will not spread to adjacent floors, sometimes the fire will expand because the fire cannot be found in the first time.
