Prefabricated building

Abstract

The invention provides a prefabricated building which comprises wall assemblies mounted on a building foundation. A floor slab assembly is arranged between every two layers of wall assemblies. A roofboard assembly is arranged at the top end of the wall assembly at the uppermost layer. Each wall assembly comprises an outer wall prefabricated component and inner wall prefabricated components used for dividing the interior of the building into a plurality of rooms. Each floor slab assembly comprises a floor slab prefabricated component arranged corresponding to the top end of each room. Door openings or window openings are reserved in the outer wall prefabricated components or the inner wall prefabricated components corresponding to the positions, where doors and windows need to be arranged,of the building. The wall assemblies, the floor slab assemblies and the roof board assembly all adopt prefabricated components, on-site rapid assembling can be achieved, using reliability is high, durability is good, impact resistance is high, materials are effectively saved, and the weight is reduced; and on-site construction procedures are simplified.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a prefabricated building. Background technique [0002] The construction industry is still stuck in the use of traditional materials and manual masonry, which consumes a lot of resources, destroys land, and wastes energy. The quality of housing cannot be improved, and the building functions cannot be improved. Civil buildings such as residences, office buildings, teaching buildings, etc., mostly adopt reinforced concrete structures. Although the use of clay bricks is avoided, there are still disadvantages such as large buildings and low prefabrication of components, which seriously affect the modernization of the construction industry. Affected the realization of housing industrialization. Some composite walls are loaded by the reinforced concrete wall on one side of the plate, and only light materials are attached to the surface of the reinforced concrete wall,...

AI Technical Summary

Problems solved by technology

This composite method makes the reinforced concrete wall thicker and its own weight increased, and the construction method is mostly on-site pouring, and the wall thickness occupied by light materials does not have mechanical significance

In addition, in the traditional prefabricated assembly construction, concrete ring beams and structural columns are installed at the floors and corners, resulting in uneven heat conduction at the joints between the ring beams and structural columns and other prefabricated components, which is prone to thermal bridge effects, resulting in Condensation, mildew and even dripping water on the wall

The most direct manifestation of the impact of thermal bridges on buildings is that the effects of winter heat preservation and summer heat insulation will be affected. In the actual construction process, external wall insulation (usually polystyrene particle insulation mortar or insulation board) is generally used, that is Wrapping the entire room or the entire building with thermal insulation materials can reduce the impact of thermal bridges very well, but this method increases the cost of the project, and the thermal insulation materials and the main body of the building need to be constructed in sections, which prolongs the construction period. , The external insulation of the external wall falls off from time to time, and the safety, reliability and aesthetics of the use are not good.

The existing CS slab structure house construction method adopts CS wall panels and roof panels (floors) as the main load-bearing components. Although energy saving has been achieved to a certain extent, thermal bridges will still occur at the reinforced concrete structural columns and ring beams of the outer walls.
