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:

How to use the machine to remove the rust spots on the surface of Steel building accessories?
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.
1. Two-hole connection accessories
One of the main accessories of Steel building accessories is the double-hole connection accessory, which is mainly used to connect with the corners. The corners on both sides of the right-angle connection can reduce the pressure on the alloy. At the same time, the recesses of the building materials can be based on the aluminum alloy frame.
2. Single hole connector
Steel building accessories also has an important accessory, the single-hole connector, which has a completely different function from the double-pipe connector. It is mainly used for the affinity connection between the aluminum alloy frame and the ground in the ground installation. Therefore, the single-hole connector has The role of anchor bolts.

Agricultural steel building is a construction of steel materials and is one of the main types of construction. The structure consists mainly of steel bearings, steel columns, steel works and other components made of profile steel and steel plates and uses silanisation, pure manganese phosphation, washing and drying, galvanising and other rust and rust protection methods.
What is agricultural steel building?
What are the characteristics of people who opt for agricultural steel building?
What are the benefits of people opting for agricultural steel building?
The agricultural steel building is characterized by high strength, low weight, good overall stiffness and high deformation resistance. It is therefore particularly suitable for the construction of large-scale and ultra-high agricultural buildings; The material has a good homogeneity and isotrope, which is ideal for elasticity. The structure most closely corresponds to the basic assumptions of general technical mechanics; the material has good plasticity and toughness, can exhibit large deformations and can withstand dynamic loads well; construction time is short; the agricultural steel industry has a high degree of industrialisation and can be specialised in agricultural production.
1. agricultural steel building has good sealing performance
Since the welding design can be completely sealed, it can be air and water-tight to high pressure containers, large oil reservoirs, pressure pipes, etc. to be processed.
2. agricultural steel building is heat resistant and non-fire resistant
If the temperature is below 150oC, the properties of the steel change slightly. The steel structure is therefore suitable for hot workshops, but if the surface is exposed to heat radiation of approximately 150, it should be protected by a thermal insulation plate. If the temperature is between 300-C and 400-C, the strength and elasticity module of the steel material decreases significantly, and if the temperature is approximately 600-oC, the strength of the steel material is zero. In buildings with special fire protection requirements, the steel structure must be protected by refractory materials to improve fire resistance.
3. agricultural steel building has poor corrosion resistance
Especially in the vicinity of moist and corrosive media, it rust easily. In general, steel structures must be rusted, galvanized or painted and regularly maintained. Specific measures such as zinc-blockanode protection are required for offshore platform construction in seawater to protect corrosion.
4.The demolition of agricultural steelworks is not subject to any building protection and the steel can be recycled and reused.
The grid structure of the agricultural steel building has an adequate load, a high stiffness, a low weight, individual rods and a comfortable production and installation. In recent years, it has often been used in public and industrial buildings with large stretches and large columns. In the construction of agricultural steel buildings there are stainless steel sandwich plates, profile plates, lighting materials and other roof materials. It can be used not only for roof constructions, but also for floors, walls and special constructions.
Agricultural steel production plays an essential role in the current industrial production process. Qingdao Xinguangzheng Steel Structure Co., Ltd. has undertaken to offer the most suitable agricultural steel buildings at a reasonable price.
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.
Residential steel building is a residential system composed of an envelope structure and a steel supporting structure. It is a new type of energy-saving and land-saving residential system. Its steel structure residence abandoned solid clay bricks and effectively used land resources. 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. A lightweight board. Special adhesive is used to bond the plate and the light steel frame, and between the plate and the plate. To prevent thermal bridges using double-layer plates.
