and step S22, assembling the prefabricated structural parts to form the building.

Alternatively, the assembly in the above embodiments includes, but is not limited to, a form of splicing or assembly.

The prefabricated building in the application refers to a building which is built by an industrialized production mode, wherein part or all components of the building are prefabricated in a factory and then transported to a construction site, and the components are assembled in a reliable connection mode.

The prefabricated building is a prefabricated building which is an attempt to search for a building using a prefabrication technology and a new construction method and material so as to be able to construct a low-cost, high-quality, site-adapted and process-adapted building.

Such prefabricated buildings can be transported in assembled form, i.e. in the form of modules or elements, for example, by disassembling the entire structure and transporting it as modules assembled on site; or in a structurally complete manner and can be transported to the site by truck or sea or rail integration, for example, the building modules are transported to the site by truck, lifted by crane and stacked in a single building, for example, each house is made up of several modules, but the floorwindows and indoor fixtures and facings such as plasterboards, tiles, bathrooms, etc. are completed off-site.

The transportation mode as referred to above can be fast building with containers, i.e. modules of container size, accommodating the building in the container, efficient transportation and construction with the dimensions and materials of the container, efficient use of the "global transportation system" (which includes huge ships, trains, trucks and crane infrastructure).

Through the embodiment, the building is built in a prefabricated assembly mode, so that the building is simple and rapid, easy to transport and assemble, safe and environment-friendly, the building manufacturing efficiency is improved, and the building cost is reduced.

In a specific embodiment, the construction process adopts a dry operation, a component workshop prefabrication and a field assembly mode; in the construction process, the material is convenient to transport, and the construction period is short. The construction of buildings adopting the materials has different specialties from other buildings, such as simple construction and short construction period. Except for land supporting facilities, the components and connectors used by the building made of the materials are processed and produced according to standards in a factory, then are transported to a construction site, and are slightly assembled to form a beautiful building.

In some preferred embodiments, the structural bamboo-based fiber composite employs the following assembly technique: all components and connectors of the bamboo-based fiber composite building for the structure are produced in a standardized way. The structural member and the connecting piece can adopt a structural bamboo-based fiber composite material structure, or the structural bamboo-based fiber composite material structure comprises the structural member and the connecting piece. Due to the fact that the accurate size of a building is known in advance, all prefabricated parts of the bamboo-based fiber composite material for the structure can be finely cut, holed and trial-assembled on a standardized bamboo-based fiber composite material for the structure through large machining equipment in a modern factory according to design drawings, wherein the prefabricated parts comprise beams, columns, wall segments, stairs, roofs, floors or whole standard component units. The construction speed is much higher than that of concrete and brick structures, and the processing efficiency is higher than that of common wood structure buildings. The prefabricated structural member is easy to transport and low in transportation cost, and complex hoisting equipment is not needed in a factory or on the site due to the light overall weight.

By adopting the embodiment of the application, the bamboo-based fiber composite assembled building for the structure has the following advantages:

first, the construction period is short: the on-site construction cycle of the structural bamboo-based fiber composite fabricated building is about 1/6 of a common brick-concrete building. The prefabricated building accelerates the construction time; according to the measurement and calculation without large-scale production, the progress of the prefabricated building is faster by more than 30% than that of the traditional construction mode. The main body of the building can be built in a factory and the foundation and infrastructure can be completed on site. The prefabricated building greatly reduces the requirements for construction workers, is beneficial to the capital circulation of development enterprises, and can improve the speed of coming into the market of houses, so that the current situation of insufficient market supply can be greatly reduced, and the supply relationship can be adjusted. After the large-area popularization, the construction cost can be greatly reduced.

Second, building styles are diversified: by adopting the beam column frame structure design, all the prior schemes can be adopted in the aspects of internal and external decoration of the building, and the design is not limited by the specificity of materials. It adopts light partition system, and the owner can change the fitment according to the needs.

Thirdly, the anti-seismic performance is strong: the adopted frame structure has strong shock resistance, and the bamboo-based fiber composite material for the structure has strong toughness, thereby providing excellent shock resistance guarantee for the bamboo-based fiber composite material for the structure.

Fourthly, the heat preservation performance is good: the foundation, the wall body and the roof are all designed in a heat preservation mode, and the heat preservation performance is very good.

Fifthly, the fireproof performance is high: the structural bamboo-based fiber composite material meets the fire-retardant grade requirement of B1 level, and the fire-retardant design is further enhanced by the limitation of material specificity when the interior decoration is designed. Wherein, the B1 grade is the B1 grade of GB 8624 and 2012 building materials and products burning performance grading.

Sixth, energy saving and environmental protection: the construction period is short, the construction is clean and simple, no waste materials such as sewage, scrap iron and the like exist, and no large noise and no electric welding operation are safer. The prefabricated building is beneficial to energy conservation and environmental protection, and is more environment-friendly in many aspects: the use and the input of the materials are better controlled, and the waste can be more effectively recycled. Through factory production and on-site assembly construction, the construction waste and the construction sewage can be greatly reduced, the construction noise is reduced, the emission of harmful gas and dust is reduced, and on-site construction and management personnel are reduced. The material can be saved by 20% generally, and the water can be saved by more than 60%.

Seventh, the security is high: it is also safer for workers to build in a factory with better safety control over a stable floor rather than at height than on site. The materials of the upper rooms or units are assembled on the factory floor by workers, and are particularly easy to manage. Some block pre-fabrication units are far better built at the factory than in the muddy area.

Eighth, the structure precision is high: compared with the traditional residential building, the prefabricated building has higher component precision, can improve common quality problems such as wall cracking, leakage and the like to the maximum extent, and improves the overall safety level, fire resistance and durability of the residential building.

The wall panels may be secured to frame beams arranged transversely or frame columns arranged vertically. The roof or floor, floor may be attached to one or more of the frame beams, secondary beams, frame columns, roof trusses, walls.

In the above embodiments, a plurality of panels (which may include walls, roofs, floors, for example) may be transported to a construction site, and the panels may be of different sizes and prefabricated according to the design of the building.
