As the strategic decision to develop energy-saving and land-saving housing and construct a conservation-oriented society is further deepened and housing industrialization has become a new growth point for the world’s economic development, the development of residential steel building will be the only way for housing industrialization.
1. Residential steel building's structural system is diversified
Many structural systems that can be used for steel structure residences have been developed, steel frame structure, steel frame-support structure, frame-tube structure (steel frame, concrete internal simplified), frame-shear wall structure (shear wall can be steel plate, concrete or concrete with built-in steel support), light steel structure and staggered truss structure system can all be used as the structural selection of residential steel building.
2. The project cost of residential steel building is slightly higher than that of concrete or equivalent
The cost of steel structure material is higher than that of concrete, but its construction period is short, the use area is large, and the number of floors can be increased under the same conditions. The project cost of residential steel building is slightly higher or equivalent to concrete, and the actual economic benefits are significant, making residential steel building It has become the first choice for high quality and low price, and the best choice for replacing masonry structure houses in the future.
Residential steel building has a high technological content. The structure itself is often the architectural expression. The performance and craftsmanship of the steel structure is not only a necessary means to realize the image conception, but also has a significant impact on the architectural image, which determines that the structural conception is the success of the image conception. The key is whether or not. The progress of science and technology and the change of aesthetics will inevitably make steel structure buildings continue to expand their expression vocabulary and seek development. residential steel building sets aside the elements of style, starts from structural rationalism, and absorbs the essence from modern and traditional styles. In the future, it will be possible to create high-quality steel structure buildings with organic integration of technology and art.
The residential steel building of the design structure and the stability calculation of components must cooperate with each other to make them consistent. The consistency between structural calculation and structural design has always been a problem that everyone pays attention to in structural design. For the joint connection requiring to transfer bending moment and not, sufficient stiffness and flexibility shall be given to it respectively, and the eccentricity of members shall be minimized for frame joints, which are often considered by designers when dealing with structural details.
However, when it comes to stability, there are often structural requirements or special considerations different from strength. For example, in terms of flexural strength of simply supported beams, the requirement for fixed hinge support is only to prevent displacement and allow rotation in the plane. However, the above requirements are not enough when dealing with the overall stability of the beam. The support shall also be able to prevent the beam from twisting around the longitudinal axis, and allow the beam to rotate in the horizontal plane and the beam end section to warp freely, so as to meet the boundary conditions adopted for stability analysis.

What is the specific process of industrial steel building construction?
How to regularly maintain industrial steel building?
How to consider the cost of industrial steel building construction?
1. Lifting the main structure of industrial steel buildings: connecting steel carriers on the ground, erecting steel columns, lifting steel carriers, connecting secondary structures, correcting the deviation of the main structure, installing crane carriers (optional), lifting intermediate layers (optional), and coating with fire resistant paint pack.
Main control quality: The deviation of the main structure should meet the specifications and design requirements and the initial and final application of high-strength screws should meet the requirements.
2. Installation of secondary structure: roofing posts, roof wall supports, flange supports, etc.
3. Laying of roof plate and insulation layer: first lay insulation layer, then assemble roof plate (in some projects a position of steel fabric is also placed under the insulation layer to prevent a fall of the insulation layer, this mainly depends on insulation layer level)
Main quality control: The roof is mainly waterproof, therefore the plate should be covered with the plate, the nail position, the glue coating should be full or not, the glue should be wiped clean and the coating on the surface of the plate should not be damaged to rust etc. to avoid.
industrial steel building wall maintenance and installation: mainly the installation of wall insulation and wall panels.
The main quality control of industrial steel building: the wall is mainly an aesthetic problem, and a window area is waterproof. There is also the problem of installation deviation. For example, the bottom should be flat, the entire plane should be flat, the flatness deviation between the board and the board should meet the requirements, and so on.
The detailed structure of the industrial steel building: mainly the installation of some trims, such as the wrap angle between the roof and the wall, the wrap angle at the corner of the wall, the flooding board between the wall panel and the brick wall, the door and window trim, etc.
The price of industrial steel building can only be compared with certain basic conditions, such as whether it is imported or domestic color panels, its thickness, coating; insulation material and thickness; whether there is a skylight; workshop bays and spans; whether there are cranes, crane tonnage, Many factors such as the level of the work system are related, and the impact of the price difference in other regions and the qualification level of the construction unit cannot be ignored.
The industrial steel building has achieved an irreplaceable position in industrial production. Qingdao Xinguangzheng Steel Structure Co., Ltd. is committed to providing different kinds industrial steel buildings of high quality for all customers from all over the world.
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.
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%.
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.
Knowing this, do you also need to order a Prefab House? Qingdao Xinguangzheng Steel Structure Co., Ltd. is committed to providing various Prefab Houses with high quality for all customers from all over the world.
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.

What are the main Steel building accessories?
How to remove the rust spots on the surface of steel building accessories?
For steel building accessories that have been used for a period of time, there are inevitably some attachments on the surface, such as rust, dirt, dust, old paint film, etc. Before painting the surface of Steel building accessories, if these attachments are not completely removed, although they can be temporarily covered after painting, they play a role of isolation, which makes the coating and the component substrate bond If the strength is severely reduced, the paint film will fall off prematurely, which will eventually reduce the corrosion resistance of the surface coating and fail to play the protective role of the coating. Therefore, before painting the surface of the component, the attachments on the surface of Steel building accessories should be thoroughly cleaned.
In order to improve the quality of rust removal and work efficiency. To improve the working conditions of construction workers, the current steel building accessories derusting work has adopted a large number of wind-driven or electric small equipment. The main rust removal methods using equipment are:
(1) Angle grinder: This small pneumatic equipment is mainly used to clean flat areas. It can use sandpaper, grinding wheels and wire brushes as needed.
(2) Needle Bundle Derusting Machine: This kind of small pneumatic equipment is generally equipped with 30-40 needle bundles, which can be adjusted with different working surfaces, which are mainly suitable for curved, narrow, uneven and cracked places.
(3) Single-head cold air gun: This small pneumatic equipment is also called zinc knocking. It uses the impact of the knocking head to remove rust. The diameter of the shovel head is generally 25-40mm, and it can impact 1000 to 6000 times per minute. Suitable for relatively narrow places.
