Loft decoration has been very popular in recent years, especially the decoration of steel structure attic is very popular with some young people. The basic components are made of steel or steel plate. According to the requirements of use, they are formed according to certain rules through welding or bolting. The bearing mechanism is called steel structure. The application of steel structures in the construction of various projects is extremely extensive. So what is the production and installation of steel structures for trousers in steel structures ? The penthouse is located in a corner of the home. Different designs make you feel inexhaustible!
Steel features:
1, lighter weight of steel structure
2, the reliability of steel structure work is higher
3, steel vibration (seismic), good impact resistance
4, the degree of industrialization of steel structure manufacturing is high
5, steel structure can be accurately and quickly assembled
6, easy to make the seal structure
7, easy corrosion of steel structure
8, poor fire resistance of steel structure
Steel structure production and installation
First, steel and wood structure
1, the main material is 120mm I-beam as the main beam, 120mm channel steel ring beam, 50mm × 50mm silicon steel construction materials for the auxiliary; construction supplies: diameter 12mm, 14mm chemical anchors, 14mm expansion screws, J422GB Bridge electrode; I-beam steel structure production: first to determine what kind of sheet in the attic (daxin board, laminated timber, pine board, particle board, etc.) such as Daxinban (size: 1220mm × 2440mm): first fixed groove steel ring during production Beams and hammers drilled and drilled out of the hole, the chemical anchors were implanted, and after the pipes were fully solidified, the channel was installed. Then, according to the special-shaped connection of the steel structure, the upper and lower steel plates were cut and inserted into the channel steel to measure the dimensions of the main beams. Do a beam of a measurement, lapped I-beam main beam, the node to implement 360 ° welding, spacing in the middle to the middle of 610mm, Daxinban to 2440mm position, the joint from the other in the I-beam, the steel segmentation size 610mm × 610mm connection is also based on the joints of the opposite sex incision joints, joints placed on the steel in the middle; this structure is installed, looking up from the ground can not see the joints, the overall steel frame to achieve the role of force evenly; of course, Concrete sheet Design and construction, no matter what kind of laminate sheets must be lapped steel, a load-bearing steel structures to facilitate, by force;
2, 100mm channel steel, 100mm × 100mm square tube production; construction process with the I-beam construction, the plate must be paved in the square pipe;
3, the room span is greater than 4000mm, we must consider the use of 140mm, 160mm, 180mm, I-beam production, the purpose is to prevent the construction after the tremble, Shen deformation phenomenon, the specific circumstances to refer to the structure of the house;
4. Advantages of this structure: The construction speed is fast, the loft has light weight, and the wall is not stressed; Disadvantages: changeable, no sound insulation; Uses: Can be used as storage room, tea room, study room, etc.
Second, the entire steel structure
1. I-beams are used as the main beams, the angle steels are used as the auxiliary beams to connect the main beams, and the I-beams are also divided according to the profiled steel plates (also known as 0, 8mm, 1, 0mm, 1, 2mm thickness of the floor tiles) Depending on the size of the lap, the I-beam can bear half of the steel plate or be over I-shaped when lapped so that the I-beam bearing weight plays a leading role. After the steel frame is lapped, the steel plate is floated, welded and welded on the steel frame, and the rebar thread grid is woven (according to the requirements for the concrete structure construction).
Threaded steel with diameter of 10mm and 12mm is tied with steel wire for special construction. Finally, the mixing of cement and sand with light material (ceramsite) is performed. Cement: sand: ceramsite ratio: 1:2:3.
2, the other is the profiled steel plate in the I-beam, welding and auxiliary beam (auxiliary beam generally 80mm channel steel; steel frame span, the main beam spacing, 120mm I-beam auxiliary beam), done After the level with the steel frame, steel mesh frame in the steel frame, the steel plate, and finally pouring;
3. Advantages of this structure: The sound insulation is not easy to be deformed, and the attic can be used as a bathroom and has a good waterproof effect. Disadvantages: The weight is heavier and the wall is stronger;
Steel structure attic should pay attention to several points
1. Before you make the attic, it is best to find several more professional loft companies to design the design of the attic steel structure.
2. Determine the material used for the attic steel structure (span more than 3.5 meters. The best use of GB steel). Some unprofessional loft companies recommend that the owner use square steel to do the unreasonable, (the square steel can not be fully rust-proof inside and outside. Easy to oxidize, the thickness is relatively thin) Correct should use channel steel or I-beam.
3, the frame structure of the house is a hollow brick, when the attic is made of steel channel should be a beam, if only a hole in the wall on the channel channel. Hollow brick single force. It is easy to draw.
4, attic steel channel steel. The maximum size of the angle steel paving is 610mm*610mm, which is determined according to blockboard 1.22m*2.44m. Otherwise it will waste a lot of board.
5. The channel and angle steel welding must be in one plane. Welding at the bottom of the channel, when the board is placed, it will not be true and must be leveled after welding.
6. The connection between channel steel and channel steel is best to use the insert welding method.
7, rust is also very important, just the structure of the package inside the moisture absorption is easy, scattered tide is difficult (especially above the toilet attic). It is best to do a descale before processing.
Editor's summary: The information about what is steel structure and steel structure loft production and installation is introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
