Description

Modularized drawer type vertical ventilation finished well Technical Field The utility model relates to the technical field of buildings, in particular to a modularized drawer type vertical ventilation finished well. Background In modern construction engineering, the performance of the floor slab and the vertical ventilation shaft in cooperation directly relates to the ventilation quality and safety of the building. The traditional vertical ventilation well has more problems, the space for installing the air pipe in the brick masonry well is limited, the construction period is long, the air pipe installation quality is low, the later maintenance and overhaul cannot be performed, the fireproof valve cannot be installed in the closed well, the air quantity adjustment cannot be performed, and the like. When a fire disaster occurs, the brick masonry collapses thickly, and the fire will spread rapidly through the well, bringing serious potential safety hazard. In addition, the traditional well is complex in construction, inconvenient to install, high in cost, easy to pollute, overlarge in noise generated in the ventilation process, and difficult and heavy in later maintenance. Therefore, a modularized drawer type vertical ventilation finished well which is stable in structure, strong in fireproof performance, convenient to install, convenient to maintain and capable of reducing noise is developed, and the modularized drawer type vertical ventilation finished well is significant in improving building quality and safety. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a modularized drawer type vertical ventilation finished well. The aim of the utility model is realized by the following technical scheme: The application provides a modularized drawer type vertical ventilation finished well, which comprises an angle steel frame, a square pipe framework, steel plates and fireproof plates, wherein angle steel hangers are welded on the side surfaces and the lower surfaces of the angle steel frame, common expansion steel structure fireproof paint is coated on the angle steel frame and the angle steel hangers, the steel plates are fixedly riveted on the inner sides of the square pipe framework, the fireproof plates are fixedly connected on the outer sides of the square pipe framework, glass wool or rock wool plates are arranged between the steel plates and the fireproof plates, and the square pipe framework is arranged in the angle steel frame in a drawer type slidable manner. Further, the fireproof plate is fixedly connected with the square pipe framework through self-tapping screws. Further, the fireproof plate is a fiber reinforced calcium silicate fireproof plate.
