Description

Light building with growing type assembly steel structure

Technical Field

The invention relates to the technical field of buildings, in particular to a light building, and particularly relates to a light building with a growing type assembly steel structure, which can be applied to buildings such as light industrial plants, temporary structures, detachable structures and the like.

Background

In recent years, due to the continuous acceleration of urbanization process in China, large-scale construction and application of concrete structure buildings bring many inevitable defects in the subsequent service life of the buildings: large occupied area, incapability of being disassembled for recycling, low space utilization rate, serious environmental protection problem and the like. The assembly type steel structure building concept is gradually accepted by people at home, and the assembly type steel structure has the advantages of efficient prefabrication processing and installation, detachability for multiple use and the like, so that new requirements of people on the building can be met. The traditional industrial factory building is mostly of a reinforced concrete structure, the main structure body is large in occupied area, large in self weight and high in manufacturing cost, and the requirement on a building site is high. The construction materials and equipment transportation required by construction are limited by sites, and the construction waste generated during construction can cause harm to the environment. After the industrial factory building with the concrete structure is built, the use space of the industrial factory building with the concrete structure cannot be flexibly changed, and the traditional industrial factory building is complex in structural form and single in building mode. After the service life is over, the construction amount of demolition is large, and demolition materials are difficult to recycle, so that the novel building concept of the current green building is not met. Therefore, how to adopt the assembly type steel structure technology to make the building space utilization diversified is very important to accord with the green sustainable production concept.

The light building mostly adopts a light steel structure as a main body, the components are produced by standardized design and batch processing, the components and spare parts are supplied in a complete set, and the components and the spare parts are installed in an on-site assembly mode. The components are usually connected by bolts. The light building structure system is short in construction period, low in construction cost compared with the traditional building, light in total weight after being built and high in building roof truss quality. The method is mainly used for factory or warehouse construction, and is particularly suitable for earthquake-stricken areas, areas with lack of building materials, remote mountain areas with poor geological conditions, projects with low cost budget or urgent construction period requirements due to the unique advantages of the construction types. The temporary building has a solid space structure, can adapt to different environmental requirements, makes site changes, moves wholly or partially, adjusts components, and can be assembled simply. The movable type combined type air conditioner is flexible in transformation, detachable in movement and convenient to transport and assemble.

However, the existing industrial factory buildings or temporary buildings generally have the defects of low space utilization rate, serious environmental protection problem, poor environmental adaptivity and the like.
