A lot of work is needed to promote and improve the design specifications and construction technical standards of different types of structures, and to develop new types of lightweight insulation wall materials and the supporting issues of residential components. At the same time, it is necessary to widely publicize the advantages of the development of Residential steel building, so that more developers, designers and users can understand and understand steel structure housing.
What are the main forms of Residential steel building?
What are the structural characteristics of these Residential steel buildings?
What should I pay attention to when using Residential steel building?
Judging from the Residential steel building that has been built, the king has:
1) Thin-walled steel composite wall panel form;
2) Pure frame form;
3) Frame support form;
4) Form of steel-concrete combination;
5) Steel frame-concrete seismic wall form and so on.
The structural forms of Residential steel building have their own characteristics. Among them, the thin-walled steel composite wall panel is particularly suitable for finalized products. The Residential steel building system evolved from the wall panel structure, that is, the thin-walled steel column members are arranged at a distance of about 600mm. The vertical load-bearing structure and section steel have a support system to resist horizontal forces. The floor slab is arranged as a multi-rib support structure according to the position of the vertical section steel. Because the upper structure is a wall-like structure, the foundation is set as a strip foundation according to the force. The foundation requirements are not high.
The thin-walled steel composite wallboard residence is affected by the dense structure, and there are certain restrictions on the size of the partitions, door, door and window openings, and pick-out components.
The latter several forms of Residential steel building can meet the design requirements of multi-story residential buildings, but there is a common problem from the perspective of use, that is, the impact of the prominent beams and columns on the interior look and feel of the residence.
Compared with other buildings, Residential steel building has its particularity. Offices and workshops can use a relatively fixed column network, and the storey height is also higher. The space occupied by the beams and columns is suitable for people. The rules of the column network are conducive to the beams. Layout. On the contrary, the residence is a product with many changes. According to the requirements of the building, a regular column network is rarely arranged. The interior space of the house is relatively small and changes a lot, which is not conducive to the layout of the steel frame.
After seeing this and learning so much information about residential steel structures, I believe you must also want to order a Residential steel building. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Residential steel building you need. At the same time, their after-sales service is also very considerate.
What is the purpose of isolation?
The purpose of isolation is to cut off the route of transmission in the infection chain,protect susceptible persons, and ultimately control or eliminate the source of infection.
Therefore, it is an important measure to prevent the spread of infectious diseases.
From a medical point of view, the goal of "isolation" is to prevent the spread of infection and ultimately eliminate or control the source of infection.
That is to prevent and limit the infectious factors of infected patients directly
or indirectly to susceptible persons,
or to those who may pass on such factors to others, and at the same time, enable infected patients to receive timely treatment under control and return to health as soon as possible.
Why choose container house?
In the construction field, it is called an assembled modular container house, also known as a container building or a container house.
It is a single room as a prefabricated unit.
The external wall panels and interior decoration of each unit are shipped to the factory after completion.
A building structure to be installed on site.
Compared with the traditional building structure, the container house has the following advantages:
(1) Convenient transportation, installation and movement, flexible combination;
(2) The cost is low and it can be completed quickly;
(3) The house can be recycled, and no construction waste is generated during use;
(4) The interior is completely renovated and can be used immediately.
Admittedly, it is precisely because of the advantages of rapid assembly and baggage check-in that the container house can be delivered to the Huoshenshan (Fire God Mountain) hospital within 10 days.
Industrial steel building has a wide range of applications and can be used in factories, warehouses, office buildings, stadiums, hangars, etc. to be used. It is suitable not only for single-storey large-space buildings, but also for the construction of multi-storey or high-rise buildings.
What are the architectural features of industrial steel building?
What is the reason why more and more people are choosing industrial steel building?
What types of construction are available for industrial steel buildings?
Insulation: Avoid heat transfer on both sides of the metal roof to ensure that the ambient air temperature is stable. The thermal protection function is realized by filling thermal protection materials (usually used glass wool and stone wool) under the metal roof plate. The heat conservation effect is expressed by the U-value and the unit is W/M2K. The thermal insulation performance is determined by the following factors: raw material, density and thickness of the thermal insulation cotton; the humidity of the thermal insulation wall, the method of connecting the metal roof plate and the underlying structure (to prevent the phenomenon of the "cold bridge"), the repeated ability of the metal coating to heat radiation.
Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain positions on the metal roof, the duration of the daylight should be adjusted to the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.
Beautiful: The metal roof of the industrial steel building has a good texture and a pleasant color.
Check the heat expansion and contraction: check the contraction shift and direction of the metal roof plate. Make sure that in areas with high temperature differences the metal roof plate is not damaged by heat expansion and contraction.
Anti-avalanche: install snow barriers on the metal roof in snow-covered areas to prevent a sudden fall of snow.
Anti-ice caps: industrial steel building can prevent rain and snow from forming ice caps on the mould.
The frame of the industrial steel building is the main structure of the system frame. It is a flat structure consisting of columns and frames. All horizontal water loads and most vertical loads are transferred to the foundation via the plant frame. In industrial buildings, the industrial steel building frame has the following three most common types of construction;
1. The single-storey steel structure factory building frame is a single-storey frame formed from the stacked column of the factory building and the frames anchored to the top of the column (the column top can be called the system bent when the column top is foldable).
2. A rigid one-storey frame, a one-storey frame formed by a rigid connection of columns with an equal or gradual cross-section and frames on the top of the column.
3. Multi-layered frame, a multi-layered frame formed by joining columns and floor supports (or specialist works) and roof supports or roof supports.
Having learned so much about industrial steel building, it is also a difficult problem to select from many manufacturers the one with high quality and low price. Qingdao Xinguangzheng Steel Structure Co., Ltd. has been a Chinese pioneer in industrial steel building for several years. You can work with customers from design to completion to ensure that all technical requirements are met.
Steel building accessories are constructed of steel materials. It is one of the main types of building structures. The structure consists mainly of steel bearings, steel columns, steel joints and other components made of profile steel and steel plates and uses rust removal and rust protection methods such as silylation, pure manganese phosphation, water washing and drying, galvanizing and so on.
Prefabricate and assemble Steel building accessories on the steel platform according to the installation sequence and process requirements to ensure the welding quality.
The spacing between the splicing joint of flange plate and web plate of section steel shall be greater than 200mm. The splicing length of flange plate shall not be less than 2 times of plate width; The web splicing width shall not be less than 300 mm and the length shall not be less than 600 mm.
In order to facilitate welding and ensure welding quality, the stiffener plates, connecting plates, base plates and cantilever beams (beams) on columns and beams shall be assembled and welded on the ground steel platform according to the dimensions of the construction drawing.
The Steel building accessories prefabricated on the steel platform shall not only be fabricated and assembled according to the construction drawings and specifications, but also consider the process of on-site installation and the change of installation size.
Some Steel building accessories users do not know that steel structures still need to be maintained and maintained. As a result, there is serious corrosion that users often can't find out, which makes steel products appear many unsafe hidden dangers, reduces the safety of Steel building accessories in use, and even affects normal use functions. It is recommended that the design unit not only put forward the painting requirements of the steel structure in the painting design description of the steel structure, but also put forward the maintenance and maintenance requirements of the Steel building accessories according to its use.
There are many ways to prevent Steel building accessories from rusting, and the following are usually used.
The steel structure is made of alloy steel that is not easy to rust
Chemical oxide layer protection method
Using metal coating protection method
Non-metallic coating protection law
In the later maintenance and maintenance process, non-metallic coating protection method is especially commonly used. The surface of the component is protected by paint and plastic, so that it does not contact the surrounding corrosive medium, so as to achieve the purpose of anti-corrosion. This method has good effect, low price, and has a wide range of paint varieties, a wide range of options, and strong applicability. It is not limited by the shape and size of the component. It can form a film with any shape on the surface of the component. The adhesion is firm. It can also follow the temperature change. The components are telescopic and easy to use. It is also possible to give the component a beautiful color.

1. From the height:
The height of the drip level of a single-storey factory building is very important. Some factory buildings are 4-5 meters high, some are 6-7 meters, and some can be as high as 11-12 meters or higher. Generally, the taller the factory building, the more difficult it will be to build, and the more expensive the material costs will be.
2. From the external building structure:
Simple iron sheet: It is the simplest, a factory built with iron sheet relatively freely.
Steel structure workshop: The steel structure workshop is divided into steel structure or ordinary steel structure. Color steel structure is more than ordinary
Concrete structure: The wall is built with bricks and the roof is sealed with concrete. This structure has better safety and heat insulation than the previous two.
3. From the internal structure:
It is divided into those with corbels and those without corbels. Only the workshops with corbels can install cranes (also called cranes). This is an important part of industrial production. If there are machinery and equipment to install cranes, just Must have corbels to use.
industrial steel building has the characteristics of forming a large space for use, easily meeting the requirements of the production process, and convenient internal transportation organization, which is conducive to the placement of heavier production equipment and products, and can realize the industrialization of the production of plant building components and the mechanization of on-site construction. Therefore, industrial steel building has been widely used in industrial buildings such as metallurgy, machinery manufacturing, motor manufacturing, chemical and textile industries. Common structural forms of reinforced concrete single-story factory buildings include bent frame structure and rigid frame structure.

Qingdao Xinguangzheng Steel Structure Co., Ltd. has been committed to providing customers with reliable industrial steel buildings and perfect after-sales service so that customers can invest easily, use them with confidence, and have no worries.
Commercial steel building is a new type of energy-saving and environmentally-friendly building system. It is known as one of the "green buildings" in the 21st century. It is an energy-saving, environmentally-friendly, and recyclable building structure.
The general sequence of commercial steel building welding is: pre welding inspection → preheating and derusting → installation and welding of base plate and arc striking plate → welding → inspection
1. Before commercial steel building welding, check the groove angle, blunt edge, gap and staggered joint, and remove the rust, oil stain and iron oxide scale in and on both sides of the groove.
2. Preheating. Before commercial steel building welding, gas welding or special baking gun shall be used to heat the groove and the base metal within 100mm on both sides evenly, and the surface thermometer shall be used to measure the temperature to prevent the temperature from meeting the requirements or local oxidation on the surface and preheating temperature.
3. Recheck the preheating temperature. If the temperature is not enough, reheat it to make it meet the requirements.
4. When assembling and welding the backing plate and arc striking plate, the surface cleanliness shall be the same as that of the groove surface, the backing plate shall be close to the base metal, and the arc striking plate shall be firmly welded with the base metal.
1. Welding: the weld bead of the first layer shall seal the connection between the base metal and the backing plate in the groove, and then weld layer by layer until the groove is filled. After each weld is welded, the welding slag and spatter must be removed, and the welding defects shall be ground away and repaired in time.
2. An interface must be welded continuously. If it is necessary to stop welding halfway, it shall be subject to thermal insulation and slow cooling treatment, and shall be heated again according to the regulations before re welding.
3. In case of rain and snow, commercial steel building shall stop welding. There shall be a wind shield and canopy around and above the welded junction of components. When the wind speed is greater than 5m / s, the welding shall be stopped. When the ambient temperature is lower than zero, preheating and post heating measures shall be taken for construction according to regulations.
4. Carbon structural steel shall be subject to weld flaw detection after the weld is cooled to ambient temperature, and low alloy structural steel shall be subject to weld flaw detection 24 hours after completion.
5. Welders and inspectors of commercial steel building shall carefully fill in the operation record form.
When purchasing commercial steel building, we should pay attention to the design of waterproof, heat-insulating and anti-corrosion of the steel structure. The design documents did not specify the steel derusting grade and paint and coating thickness, and did not adopt corresponding measures according to the different fire resistance limits of different parts. commercial steel building of thermal insulation protection measures needs to be avoided.
Commercial steel building has focused on the development and production of commercial steel buildings for several years. And it commits to provide perfect service for every customer 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.
