Description

technical field [0001] The invention relates to the technical field of building prefabrication and assembly, in particular to a standard modular component for building and a prefabricated building containing it. Background technique [0002] In the field of building prefabrication and assembly technology, domestic and foreign materials can be basically divided into: 1. PC structure; 2. Steel structure; 3.

Glass structure; Form, the above-mentioned structural materials are used to complete the production of prefabricated components according to the design drawings, and then the prefabricated components are connected through joints on the construction site to achieve a safe mechanical performance of the overall building structure. , prestressed, welding, bolts, buckles, etc., or a combination of multiple connections to complete all building structure connections. [0003] There are the following problems in the above structural forms: [0004] 1. PC stru...

AI Technical Summary

Problems solved by technology

[0006] 1) The prefabricated structure is self-heavy. Compared with non-large-span and light-loaded buildings, it will cause a drastic increase in building structure, transportation costs, and on-site installation costs. The excessive consumption of various resources is very large, so it is very uneconomical

[0007] 2) Extensive use of concrete materials that damage the environment and consume resources does not meet the advanced technical requirements for green energy saving and emission reduction

[0008] 3) The prefabricated components of this kind of structure are relatively large and due to their materials, the precision of factory prefabricated control and processing is severely limited, and it often happens that the components do not meet the standards and cannot be assembled on site

And due to the heavy weight, it is very difficult to assemble on site, the workload of the secondary seam treatment is large, and the construction efficiency is low

[0009] 4) Since this structure is made of cementitious materials, collision damage often occurs during transportation and installation, and the difficulty and cost of finished product protection are relatively high

[0010] 5) Grouting or welding is often used for component connection, the workload of on-site wet work is increased, and the requirements for manual operation in the on-site installation process are relatively high, which greatly loses the meaning of prefabricated processing precision in component factories

[0013] 1) Due to the material stability of the steel structure itself, compared with this type of housing, its material performance cannot be fully utilized. The cross-section of the beam and column system is relatively large, and the consumables are uneconomical

[0014] 2) Since the factory is prefabricated into basic unit components, the components have many specifications and are subject to different building forms, so it is impossible to form a general standard component, and the installation cannot form an efficient standardization

[0015] 3) Combined with the requirements of architectural forms, some steel components must be welded, and the quality of on-site welding is difficult to control. At the same time, regardless of on-site welding or factory prefabricated welding, stress concentration areas will be formed on the material surface, and safety hazards are difficult to control

[0016] 4) Due to the wet welding on site, the fireproof material of the steel member is damaged, which also has potential safety hazards, and the appearance quality is difficult to guarantee

[0019] 1) Given the current situation in our country, with a large population and a serious shortage of corresponding forest resources, it seems impractical to use a large amount of wood in building houses in our country

[0020] 2) At present, the processing of wood itself and other technical problems such as anti-corrosion and insect-proof are difficult to solve, and the corresponding costs are relatively large

[0021] 3) In prefabricated timber buildings, due to the material characteristics of the timber itself, the floor panels have relatively large elastic deformation, which affects the comfort of use

[0025] 1) Traditional prefabricated components must be designed for a single building. After the structural design is finalized, the prefabricated components are disassembled for factory prefabricated production and on-site assembly. It is impossible to combine the processed general standard units to determine the design and installation.

[0026] 2) Traditional prefabricated components such as: cold-formed thin-walled steel structures are mostly produced by pressing rods of various specifications on site for installation and production. There are too many standards for components, and there are many connection points. The efficiency of on-site installation is low and the quality is difficult to control.

[0027] 3) Traditional prefabricated components such as: PC structure, large component size is not convenient for transportation, and the workload of wet work on site is heavy, and the quality is difficult to control

[0028] It can be seen that the above-mentioned existing various prefabricated structures obviously still have inconvenience and defects in structure, method and use, and need to be further improved urgently.
