Abstract

The invention relates to a prefabricated steel structure equipment pit and a construction method. The pit body construction and installation problems that in traditional construction, booth boxes, fire hydrants and other equipment pits are designed for structural floors in exhibition halls, and the equipment pits are not prone to form erecting are solved. According to the prefabricated steel structure equipment pit, the concrete structure is adjusted to be the steel structure, holes are reserved in the design location, and the prefabricated steel structure is supported and connected with angleiron. Inner wall and outer wall coating of a prefabricated steel structure steel plate is conducted according to the steel structure design specification, steel plate outer wall finishing coat adoptsa fire retardant coating, the duration of fire resistance meets building fire design requirements, and then the construction difficulty is lowered, and the constriction quality is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of prefabricated steel structures, and specifically relates to a prefabricated steel structure equipment pit and a construction method thereof. Background technique [0002] Conventional concrete structure floor fire hydrant equipment pits and booth box pits are mostly concrete structures. In order to meet the construction requirements of concrete structure floor slabs, temporary support bents need to be set at the lower part, and then concrete is poured. The construction is complicated and the risk factor is high. Usually such pits are not easy to support formwork when they are located on higher floor slabs, and will cause significant adverse effects on subsequent mechanical and electrical installation and masonry structure construction. [0003] Therefore, how to provide a prefabricated steel structure equipment pit and its construction method that is convenient for construction and cost-saving is a technical pro...
