Prefab house is a structure mainly made of steel, which is one of the main building structure types. The characteristics of steel are high strength, light weight, and high rigidity, so it is especially suitable for the construction of large-span, super-high and super-heavy buildings.
Compared with traditional concrete buildings, what are the advantages of Prefab house?
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 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.
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.
