What are the advantages of Prefab house?
What is the installation process of Prefab house?
Compared with prefabricated concrete buildings, Prefab houses have the following advantages:
1. There is no on-site cast-in-place node, the installation speed is faster, and the construction quality is easier to be guaranteed;
2. The steel structure is a ductile material with better seismic performance;
3. Compared with concrete structure, steel structure has lighter weight and lower foundation cost;
4. The steel structure is a recyclable material, which is more green and environmentally friendly;
5. Well-designed steel structure prefabricated buildings are more economical than prefabricated concrete buildings.
6. The cross-section of beams and columns is smaller, and more usable area can be obtained.
Save heating costs
Prefab house is more energy-efficient and environmentally friendly when used in the home, such as a new type of thermal insulation layer that has a better thermal insulation effect. When a household measurement is implemented and the heating has the same temperature, the room temperature of the "assembled" space is higher. The head of household may consider lowering the heating temperature, saving heating costs and, at the same time, reducing energy consumption.
Save energy
Finished house is of great benefit for energy saving and environmental protection. Through factory production and on-site assembly, it can significantly reduce building protection and waste water, reduce building noise, reduce harmful gas and dust emissions and reduce building and management personnel on site.
The assembly procedure for the steel construction of the Prefab house: steel column assembly -Installation of the supports between the columns -temporary installation of the steel bearer -roof bearings, roof bearings -correction and fixing of the steel bearer -Installation of the maintenance structure.
1. Contamination protection: Avoid rain water entering the metal roof from the outside. Rainwater enters the metal roof mainly through overlapping joints or knots. In order to achieve the function of the centrifuge, it is necessary to use a sealing disc at the screw connection and to make a concealed fixation. Use sealants or welds on the top of the plate. Best use a long board to remove the overlap. Close water-tight treatment for bleeding.
2. Moisture resistant: Avoid condensation of water vapour in the soil and metal wax layer and drain the water vapour in the metal wax 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.
3. Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain points on the metal roof, the duration of use of the daylight should be aligned with the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.

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.
The Steel building accessories have been widely used in daily life and industrial production. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Steel building accessories for their customers.

Prefab House refers to the use of industrial production methods to build houses, that is, the stairs, exterior walls, balconies, air-conditioning panels, etc. of the house are all prefabricated in the factory outside the construction site, and then shipped to the construction site for "assembly", and the interior of the house will be refined at one time. Handed over after renovation. That is, the huge external walls, stairs, and balconies from the factory are "assembled" on the construction site into houses and buildings.
What are the advantages of a Prefab House?
What are the structural types of Prefab Houses?
What should we be careful about when selecting a Prefab House?
1. Safe and reliable
The Prefab House with steel as the main building material has a high capacity per volume unit, is more stable and solid than the traditional brick and brick concrete technology, has a better seismic performance, wind resistance, water density and refractory performance and also has thermal insulation and sound protection functions. Steel has good ductility and can better use the energy brought in by earthquakes, so it has good seismic performance and a high structural security t hat guarantees the safety of stay.
2. Easy construction and short construction time
All components are prefabricated in the factory and only have to be installed on site, which greatly shortens the construction cycle. A 6000-square-metre-long building can basically be installed in 40 days.
1. Structural system
The structure of the Prefab House can be divided into: steel frame system, steel frame support system, steel frame-core tube system, steel frame-module-core tube system and steel frame-shear-wall system. With the continuous development of the technology, newer steel construction systems will also appear.
2. Peripheral protection system
The outer protective system of the Prefab House can be divided into blocks, plates, cans and other types.
3. Internal system
Traditional construction has many disadvantages. For example, the traditional rough decoration method does not separate the interior system and the structural system, which makes it difficult to adapt to the modern development of the housing industry; the house technology lines are not separated and the water and power lines are buried in the support layer, which the "century residence" cannot realize." The waste of social resources is serious.
1.The costs are relatively higher than in the traditional Prefab House made of brick concrete and concrete.
2. The steel structure of the Prefab House, with its unique steel structure, walls, roofs and other materials, as well as the standardized and final internal distribution and support facilities, is difficult to adapt to the habits of people "arbitrarily handling the house".
3. Corrosion of steel: Al-galvanized steel must be used for maximum corrosion protection and the main steel structure can reach fifty years.
4. There are many requirements for new materials. The structure of steel houses is equipped with materials such as thermal insulation and heat protection, usually using new lightweight materials.
Prefab Houses produced by Qingdao Xinguangzheng Steel Structure Co., Ltd. feature attractive appearance, excellent performance, user-friendly operation, easy maintenance, and internationally advanced performance indicators, and are exported to more than 10 countries and regions.
