Residential steel building has entered a new stage of development. Relevant specifications and design standards have been issued and implemented one after another. In addition, the supply of steel is sufficient. A batch of Residential steel building trial construction experience and scientific and technological achievements continue to be presented. The development of Residential steel building Have a good material and technical foundation
How will Residential steel building develop in the future?
What should be considered before building Residential steel building?
What are the issues that need to be considered when constructing Residential steel building?
Due to the flexibility of Residential steel building design, in addition to high-rise buildings, low- and multi-storey residential buildings also have good adaptability for the residential system. At the same time, the development of villas in low- and multi-storey houses can use light steel structures such as cold-formed C-shaped steel or Small hot-rolled steel forms a keel structure system; high-rise buildings can use hot-rolled H-shaped, welded H-shaped, welded box-shaped, cold-formed thin-walled square steel pipe filled with concrete, round steel pipe filled with concrete, etc. to form a steel frame body and steel support frame system , Steel frame concrete shear wall system, etc.; while building villas and rural buildings, wall column systems can be used.
1. The cooperation between building equipment and Residential steel building is the first problem encountered by residents. Therefore, how to use advanced technology to develop various equipment suitable for steel structure residence is a problem we must solve.
2. The cost of Residential steel building is the most concerned issue of real estate developers. Steel structure residence should be located in medium and high-grade residence. Steel structure residence building is a systematic project. Management and coordination should be strengthened from the links of design, manufacturing, transportation, installation, maintenance and management, so as to reduce costs and improve comprehensive economic benefits.
What are the issues that need to be considered when constructing Residential steel building?
1. Selection and development of exterior wall panels for Residential steel building is one of the key issues in the promotion of steel structure residential buildings. In addition to meeting the technical requirements of exterior wallboards, it is also necessary to make wallboard raw materials suitable for local conditions, work-oriented production, transportation, installation and connection.
2. The structure of Residential steel building should be safe and reasonable, the node structure should be convenient and reliable, and create conditions for component production, transportation and hoisting.
3. The seismic performance of Residential steel building has a lot to do with the regularity of structural layout. The structure layout is irregular, it is easy to be damaged during an earthquake, and in addition to the elastic design, the elasto-plastic layer displacement check calculation is also required. Therefore, we should try our best to make the structural layout meet the regularity requirements.
Overall, the important role of Residential steel building in our daily lives is perceived by more and more people. Qingdao Xinguangzheng Steel Structure Co., Ltd. strives to offer high quality Residential steel building at reasonable prices, efficient production times and the most professional customer service.
At present, the construction technology of large-space steel structure construction has made great progress, and the "folding and unfolding" construction technology is a construction method that fully expresses the changes in the construction process of large-span space construction. He turned a large structure into a movable mechanism; the industrial steel building is so popular nowadays mainly because its advantages surpass the previous buildings.

What is the meaning of industrial steel building?
The use of steel construction in industrial steel building has the advantages of shorter construction period, higher application rate, sensitive plan, column spacing and large span. As far as the owner is concerned, industrial steel building can shorten the investment construction period and work quickly. The components can be disassembled and re-applied, which promotes environmental protection and saves resources. Therefore, the application in modern industrial design is becoming more and more common.
What should I pay attention to when installing steel columns in industrial steel building?
(1) Due to the heavy weight and long length of the steel column, the industrial steel building cannot be manufactured and transported at one time. Therefore, the method of segmented manufacturing and on-site assembly as a whole is used for hoisting. It is planned to divide the steel column into two sections. The steel column is transported to the site in two sections, the lower lattice part and the upper H-shaped steel column. The weight of the steel column is about 6 tons, and the height in place is about 17 meters. A 50-ton truck crane can meet the hoisting needs, supplemented by a 25-ton truck crane for hoisting.
(2) The hoisting adopts single-machine rotary hoisting. Before lifting, padded wooden squares at the position of the steel column foot plate to prevent the steel column from damaging the foot plate during the lifting process. When the steel column is hoisted, the crane should lift the hook while turning the arm to make the steel column vertically off the ground and put the column into the mouth of the cup.
What should be paid attention to when constructing industrial steel building?
Ventilation: air exchange in indoor and outdoor areas. Put air vents on the metal roof.
Moisture resistant: Avoid condensation of water vapour in the lower layer of the metal roof and metal roof layer and drain the water vapour in the metal ceiling layer. The solution is to fill the metal roof with thermal insulation cotton, place a waterproof membrane on the metal floor plate and have ventilated knots on the metal roof.
Carrying: construction load, rain, dust, snow pressure, maintenance load. The load bearing capacity of the metal roof depends on the cross-section characteristics of the plate type, the strength and thickness of the material, the power transfer method and the distance of the horses (sub-horses).
Lightning protection: Take the lightning to the ground to prevent the lightning from penetrating the metal roof and entering the room.

Color steel insulation sandwich panel is the basic materials for steel structure buildings, which is suitable for steel structure industrial plant. It is composed of two layers of formed metal panel and directly foaming, curing molding polymer heat insulation inner core. Color steel insulation sandwich panel commonly used insulation materials are: glass wool, polystyrene(EPS), polyurethane(PU), Rock wool and other insulation materials.
Then, what's the difference between these three insulation materials?
1) Glass wool sandwich panel. Glass wool is a good inorganic thermal insulation material, glass wool is obviously characterized by good fire resistance, flame retardant and moisture absorption, and its price is cheap. The thermal conductivity of the glass wool sandwich board is not greater than 0.038 W/(m2•K).
2) Polystyrene (EPS) sandwich panel. Polystyrene is a polystyrene resin as the main raw material, through the foaming agent foaming and made of internal with numerous closed micropores. Its insulation effect is good, the price is cheap, the strength is slightly poor. Polystyrene (EPS) sandwich board, thermal conductivity is not greater than 0.038W/(m2•K).
3) Polyurethane(PU)sandwich panel. The thermal conductivity of polyurethane sandwich board is no more than 0.033 W/(m2•K), with good thermal insulation performance, good water resistance, good thermal insulation effect, high strength, foam can be made into any shape, suitable for site construction, but the price is expensive.
To meet different thermal insulation requirements, consider the thermal conductivity of the steel structure material and the thickness of the insulation layer. The thermal conductivity of commonly used steel structure insulation materials is as follows: polyurethane foam> polystyrene foam >glass wool > rock wool.

The light steel structure of commercial steel building is a structure composed of steel materials, and each component or part is connected by welding, bolts or rivets.
commercial steel building is mainly used for low-rise or multi-storey buildings: the prefabricated wall panels are transported to the construction site by special vehicles, hoisted by cranes, connected with the foundation by anchor bolts and connectors, and the wall panels are connected by screws and connectors, and then the light steel floor is installed. The light steel floor is composed of floor beams, profiled steel plates Steel wire mesh and concrete. The construction of the main structure can be completed by constructing the upper floor according to the construction method of one floor and finally installing the roof. The system is applicable to buildings with 6 floors and below. It has the advantages of high assembly rate, short construction cycle, earthquake resistance and typhoon resistance, thermal insulation, large use area in the sleeve, no exposed beams and columns, and recyclable materials.
What are the architectural advantages of commercial steel building?
1. The construction period is short. The construction period of commercial steel building can be shortened by more than 50%;
2. The project quality is stable. The quality of parts and components produced in commercial steel building factory is more stable, which solves many common quality problems of on-site construction technology and human errors in on-site construction, and ensures the project quality;
3. Energy saving and environmental protection, less construction pollution. commercial steel building adopts energy-saving technology, which greatly improves the performance of house thermal insulation and sound insulation, and improves the living comfort of the building. According to statistics, the prefabricated construction method can save about 50% water, 70% wood and 70% construction waste;
4. Integrated decoration, which is carried out simultaneously with architecture, structure and electromechanical design. commercial steel building completes the pre functional conditions, pipeline installation, wall decoration and component installation in place at one time, which not only ensures the decoration quality, but also avoids the repeated waste and secondary pollution of secondary decoration.
1. Variability
The construction quality problems of commercial steel building will continue to evolve and change with external changes and the extension of time, and quality defects will gradually manifest. For example, the welds of steel components cause cracks in the welds that did not originally have cracks due to changes in stress: delayed cracks can occur due to the activity of hydrogen in the welds after welding. In addition, if the component is subjected to long-term overload, the steel component will be bent and deformed under the arch, which will cause hidden dangers.
2. Frequent
When faced with the relatively unfamiliar construction and construction techniques of steel structures, managers and technicians engaged in construction must be very careful and trained before they can take up their posts.
Knowing this, do you also want to order a commercial steel building? Qingdao Xinguangzheng Steel Structure Co., Ltd., which has been a Chinese pioneer in commercial steel building for many years. Their skilled staff can use the best solution for anything, particularly when a custom product is required.

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.
What should be paid attention to during the installation and welding of commercial steel building?
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.
