The beam-column joints of Prefab House are mainly connected by bolt welding. However, bolted joints are recommended for fabricated steel structures. The advantage of bolted connection (weld-free connection) is that the installation speed is fast and the construction quality is easier to control.
1. The construction period is short. Generally, the first floor of Prefab House can be built in three or four days, and it only takes one or two days. Steel structure residential systems are mostly manufactured in factories and installed on-site. The amount of on-site work is greatly reduced. Therefore, the construction period can be greatly shortened, and the noise and dust generated during the construction, as well as the consumption of on-site resources and various on-site expenses are correspondingly reduced. Compared with reinforced concrete structures, the construction period can generally be shortened by one-half, the investment benefits can be brought into play in advance, capital turnover can be accelerated, and construction costs can be reduced by 3%-5%.
2. Good seismic performance. Because the steel of Prefab House is an elastically deformable material, it can greatly improve the safety and reliability of the house. The steel structure has high strength, good ductility and light weight, which can greatly improve the mechanical performance of the structure, especially the seismic performance. Judging from the situation after the earthquake at home and abroad, the number of collapsed steel structure residential buildings is very small.
In line with the development direction of building energy efficiency. Prefab House uses steel as the frame and thermal insulation wallboard as the enclosure structure, which can replace clay bricks, reduce the amount of cement, sand, stone, and lime, and reduce the damage to non-renewable resources. On-site wet construction is reduced, and the construction environment is better. At the same time, steel can be recycled and reused, and the environmental pollution during construction and dismantling is small, and its energy saving index can reach more than 50%, which belongs to the green building system.
The application of steel structure in Prefab House has opened up a new application market for my country's steel industry. It can also drive the research and application of related new building materials.
Steel-finished house is generally a residential building constructed with factory-made, economical steel profiles as a supporting work and new lightweight, heat-conserving, heat-insulating and high-strength wall materials as a home. The industrialisation of the steel building house refers to the use of steel construction houses as the final product. Through socialized mass production, the process of investment, development, construction, construction and customer service of steel dwellings is centralised and unified into an overall organisational form. The industrialization of the steel building house is the development trend of the steel building house.

What are the advantages of Residential steel building?
What raw materials should be used for the walls of Residential steel building?
What is the roof system of Residential steel building?
1. Superior seismic performance
Compared with traditional residential structures, Residential steel building is a flexible structure and has a lighter weight. Therefore, buildings with the same fortification intensity and the same site will bear less seismic force, and the earthquake disaster caused by them will be weakened accordingly. The use of steel in the earthquake zone Structural housing will reduce casualties and property losses, with considerable comprehensive benefits.
2. Flexible layout and increased effective use area
Residential steel building adopts steel structure, which can realize large span under the premise that the cross-section is not too large, which makes the building function very flexible and can be flexibly arranged according to the needs of residents, which is conducive to meeting the needs of modern homes and adapting The needs of the modern housing market. Moreover, the steel structure is adopted, the cross-section of the beams and columns is small, and the use area of the residents is increased at the same time.
Residential steel building's steel frame system, steel frame-support system, steel frame-concrete core tube (shear wall) system outer walls can be filled with small concrete block walls, autoclaved lightweight aerated concrete slabs, and prefabricated reinforced concrete walls Board, steel wire mesh frame polystyrene sandwich panel, fiber cement external wall hanging panel, polyurethane composite external wall panel, metal surface embossed composite panel, etc. The inner wall can be made of glass fiber strong gypsum hollow board, fiber cement board infusion (foam concrete) wall, light composite wall board, etc.
1. The flat roof of the Residential steel building adopts steel beams (I-beam, C-shaped steel), prefabricated reinforced concrete roof panels, and thermal insulation and waterproof layer.
2. The sloping roof of Residential steel building adopts portal frame, truss, light steel keel truss (bracket), I-shaped (or C-shaped) and steel purlin, colored cement tile, colored steel plate tile and colored asphalt tile roof.

Prefab House refers to a building where parts and components produced in a factory are assembled and connected at the construction site. Steel structure prefabricated buildings refer to steel structure components produced in factories and assembled and connected at the construction site.
Different countries have different understandings and practices of the housing system, but Prefab House generally refers to the main project of the house. Different residential products are formed due to the selection of different structural materials, structural types and construction methods, and constitute a number of corresponding residential products ranging from design to The complete technology of construction. The steel structure residential building system uses the steel structure form as the basis for the classification of the building system and becomes a branch of the building system.
The material of Prefab House has good homogeneity and isotropy, which is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformations, and can well withstand dynamic loads; construction period is short ; It has a high degree of industrialization and can be used for specialized production with a high degree of mechanization; it has high processing accuracy, high efficiency, and good airtightness, so it can be used to build gas tanks, oil tanks, and transformers.
In the future, the steel structure of Prefab House should study high-strength steel to greatly increase its yield point strength; in addition, new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel), T-shaped steel and profiled steel plates, etc. The needs of large-span structures and super high-rise buildings.
(1) Light weight and high strength. Due to the use of steel as the load-bearing structure and new building materials as the enclosure structure, Prefab House generally uses steel structure to build residences that weigh about one-half of the weight of reinforced concrete residences, which reduces the weight of the house and reduces the cost of basic engineering. Since the building area occupied by the vertical force-bearing member is relatively small, the use area of the house can be increased. At the same time, because the steel structure residence adopts a large bay and large depth column network, it provides residents with a large space that can be flexibly separated, which can meet the different needs of users.
(2) The degree of industrialization is high and meets the requirements of industrialization. Most of the structural components of Prefab House are made in factories, which are easy to install and suitable for mass production. This has changed the traditional way of housing construction and realized the transformation from "building houses" to "manufacturing houses". Promoted the transformation of the housing industry from extensive to intensive, and at the same time promoted the development of productivity.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has worked on the production of Prefab Houses for several years. You can find the best Prefab House in this company.
How much do you know about the Agricultural steel building?
When you consider the building materials used in a new construction project, you will feel uneasy.

What is the layout of the residential steel building?
What issues should be paid attention to when designing residential steel building?
Why pay attention to the design of residential steel building?
residential steel building’s column grid layout should be regular, and it is advisable to use residential units or sleeves as the unit to achieve modularity. The modular flat connection, wrong connection and symmetrical concave (convex) connection and other splicing adapt to changes in the overall layout .
When the residential steel building module adopts small column net, it should be combined with the floor and pipeline design; when the module adopts large column net, the facility pipeline should be designed as a fixed-positioned tube bundle, and the electrical and communication lines can be along the cavity and skirting of the partition wall. , Mirror hanging line or top line arrangement.
The kitchen and bathroom are located close to the concrete core tube or concrete shear wall, and avoid steel structure load-bearing components to facilitate the fire prevention and anti-corrosion treatment of steel components.
Vertical pipelines are centrally arranged in pipeline wells or pipeline walls, or installed on site using factory prefabricated tube bundles.
The toilet is drained on the same floor. Use a double pipe system for centralized heating, and use a temperature control valve and a heat meter. Use the equipotential characteristics of the steel structure to make a natural ground connection.
residential steel building should be dominated by construction and design, and other professions should interact closely with each other. In addition to following the general principles of residential building design, residential steel building must also focus on solving:
(1) How to make use of the advantages of steel structure? The beam span can be enlarged, the bays can be more flexible, and more space can be created for residents. But how to avoid the flatness and monotonous facade of the building caused by the steel structure.
(2) It is necessary to solve the fire protection and anti-corrosion problems of steel structure residential buildings. Especially in rainy areas, the quality of anti-corrosion and anti-rust work directly affects the promotion of steel structure housing.
The cost of residential steel building is the most concerned issue of real estate developers. Steel structure residences should be positioned in middle and high-end residences. Steel structure residences are a systematic project. Management and coordination should be strengthened from design, manufacturing, transportation, installation, maintenance and management, so as to reduce costs and improve overall economic benefits. the goal of.

Compared with traditional houses, steel structure houses have advantages in terms of use function, design, construction and comprehensive economy.
What are the reasons why people choose Residential steel building?
What should the choice of Residential steel building structural system look like?
What is the framework system used by Residential steel building?
1. Residential steel building energy saving and environmental protection
The main body of the Residential steel building is steel components, and the wall material is thermal insulation mortar, which not only meets the requirements for energy saving, but also can be recycled. It is a green and environmentally friendly recycling building that meets the requirements of sustainable development. The thermal resistance can reach a brick wall thickness of about 1m. At present, the global population is large and energy consumption is large, and the promotion and application of steel structure housing is the final choice.
2. Residential steel building's pipe network line layout is convenient
In residential buildings, there are many lines of professional plumbing and electricity pipe network, which will reduce the effective use area in traditional buildings. In Residential steel building, there are many holes or holes in beams and columns, which is easy to form a cavity for wiring layout. Moreover, the beam can be artificially made into a honeycomb shape, which is convenient for line layout, which not only saves the net height of the building, but also increases the use area.
According to engineering practice, the commonly used Residential steel building structure system can be selected with reference to the following scope:
The 4th to 6th floors are the steel frame system, the steel frame-support system, and the steel frame-shear wall system; the 7th to 12th floors are the steel frame-concrete core tube (shear wall) system.
The section form of steel components should be hot-rolled H-section steel, high-frequency welded H-section steel and steel tube concrete.
Light steel frame system
The light steel frame system is a load-bearing frame composed of hot-rolled H-shaped steel (or I-beam), high-frequency welded H-shaped and cold-formed square pipes, and a steel structure residence with composite curtain walls or infill walls as the enclosure structure system.
The wall panels in the picture collection are made in the factory with fly ash as the filler, sulfoaluminate as the cement, polystyrene foam (EPS) as the core material, and glass fiber mesh as the reinforcement material.
