Description

Technical Field

[0001] The utility model belongs to the technical field of light steel houses, and particularly relates to a structural enclosure of a light steel house with fire resistance performance. Background Technique

[0002] A light steel house refers to a house built with light steel keels as the main building materials, which is constructed through precise calculations and the support and combination of accessories. The main materials of this building are synthesized by cold rolling hot-dip galvanized steel strips. The seismic performance of the light steel structure is far superior to that of traditional concrete and brick-concrete houses. At the same time, due to the light self-weight of the light steel structure, the unit area weight is only equivalent to 1 / 4 of the weight of the brick-concrete structure of the same area. Therefore, its foundation treatment is simple and suitable for most geological conditions.

[0003] However, although the current light steel houses bring convenience to people, there are still some deficiencies in the process of use. The existing light steel houses have low fire resistance and are not easy to meet the requirements of building fire protection. Content of the Utility Model

[0004] The purpose of the utility model is to provide a structural enclosure of a light steel house with fire resistance performance, aiming to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

The roof truss is fixedly installed on the top of the light steel bottom frame, and the roof board is fixedly installed on the top of the roof truss. The roof truss includes steel columns, light steel main beams and light steel secondary beams. A plurality of the steel columns are all fixedly installed on the top of the light steel bottom frame, the light steel main beam is fixedly installed on the top of the steel column, and a plurality of the light steel secondary beams are fixedly installed in the middle part between two light steel main beams. The light steel bottom frame and the roof truss are both made of light steel keels, and a fireproof coating is arranged on the outer surface of the light steel keels.

[0007] As a preferred scheme of the utility model, an exterior wall board and an interior wall board are fixedly installed between a plurality of the steel columns, and a hot-dip galvanized keel is fixedly installed in the middle part between the exterior wall board and the interior wall board.

[0009] As a preferred scheme of the utility model, both the exterior wall board and the interior wall board are arranged as fireproof gypsum boards.

[0010] As a preferred embodiment of the present utility model, the fireproof board is made of calcium silicate board and gypsum board, and the heat insulation board is made of glass fiber and rock wool.

[0011] As a preferred embodiment of the present utility model, the roof board includes particle board one, heat preservation and insulation layer, ventilation layer, particle board two and waterproof coating. The particle board one is fixedly installed on the top of the roof truss, and the heat preservation and insulation layer is fixedly installed on the top of the particle board one.
