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.

Introduction of Zhongjie era Steel Structure Frame Overpass Project
Zhongjie Times Square overpass project is the first Cross Street overpass project in Pingdu. The whole project is composed of three overpasses. The length of the straight overpass on the east side is 56.3 meters and the width is 5 meters. The length of the straight overpass on the west side is 49 meters and the width is 5 meters. The diameter of the main bridge surface of the central circular overpass is 56 meters. The narrowest part is 6.5 meters and the maximum width is 12 meters. The construction of the overpass on Hongqi Road can avoid the interference of people and vehicles To improve the road capacity, and effectively solve the problem of efficiency and safety of a large number of people crossing the street.
After completion, it will become the most characteristic commercial block with urban flavor in the main urban area of Pingdu City, as well as the landscape landmark and cultural landmark of Pingdu.
Agricultural steel building has low cost, short construction time, and less pollution. Therefore, it has become the best choice for new-style construction.
Structural parts: material, surface roughness, tolerance, surface treatment, straightness (or radian)
Connection: hole position deviation, bolt grade; welding method, welding standard, welding material; air tightness, non-destructive testing, liquid penetration testing, etc. are required
Overall structure: verticality, horizontality, etc.
Packaging: packaging materials, packaging methods
Storage: ambient temperature, ambient humidity
Transportation: loading and unloading, placing in vehicles, placing in containers, etc.
Fire protection technology. One of the most critical issues in agricultural steel building is the application of fire protection technology. The fire resistance rating of light steel structure houses is level 4. For light steel structure residential buildings, fire-resistant gypsum boards are pasted on both sides of the wall and the ceiling of the floor. For ordinary firewalls and household walls, 25.4 mm thick (1 inch) gypsum boards are used to protect them to meet the 1-hour fire protection requirement. The glass fiber filled between the wall columns and the floor joists also plays an active role in protecting fire and heat transfer.
Sound insulation technology. The agricultural steel building is filled with glass wool between the inner and outer walls and the floor joists, which effectively prevents the audio part transmitted through the air. For the impact sound transmitted through the solid, the following construction is performed: the partition wall is composed of two wall columns. There are two walls with intermediate spaces; for the small keel used to fix the gypsum board for the suspended ceiling, an elastic structure with small cut grooves is used to effectively reduce the transmission of structure-borne sound between floors.
If an agricultural steel building is damaged, we must immediately recognise and remedy the problem. The main factors of steel structural damage are:
(1) the structural viability of agricultural steel buildings is insufficient due to changes in load, overdue service and changes in rules and regulations;
2) The components of agricultural steelworks are deformed, twisted, damaged, deformed, etc., due to various accidents; which results in a weakening of the cross-section of the component, a twisting of the rod and a tearing of the connection;
(3) deformation, cracking and retardation of agricultural steel components or connections due to temperature differences;
4) The agricultural steel structure corrodes due to the erosion of chemical substances and electrochemical corrosion leads to a weakening of the cross-section of the steel structure;
5) Other include errors in design, production, construction and illegal use and operation during the service period.
There are three main technical reinforcement measures for agricultural steel construction:
1) Cross-section defences: Apply the element locally or over the entire length of the element with steel and connect it to a whole to carry the force together;
2) Change the calculation diagram: add additional supports, adjust load distribution, reduce cutting force level, force displacement of static indefinite structural support and reduce peak voltage;
3) Pre-tensioned cable method: use high-strength cables to strengthen the weak links of the structure or to improve the overall durability, stiffness and stability of the structure.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has been developing agricultural steel buildings for many years, and is known as "the national brand leader in the Chinesesteel building industry". Therefore, customers can choose their products with confidence.
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.
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.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has been committed to providing customers with residential steel buildings and perfect after-sales service so that customers can invest easily, use them with confidence, and have no worries.
The development of residential steel building conforms to the industrial technology policy of protecting arable land and saving energy, and is also one of the production methods for realizing residential industrialization. The development of steel structure housing is the general trend.
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.
Qingdao Xinguangzheng Steel Structure Co., Ltd. strives to provide top-quality residential steel buildings with reasonable prices, efficient production time, and the most professional customer service.
