  • Detail

The installation and construction of attic steel structure is the process of adding steel structure on the basis of the original structure. The construction process should not only protect the original structure from damage, but also ensure that the new structure can be used safely and well for a long time. From the perspective of safety, economy and science, the main processes of steel structure attic construction are construction preparation, material procurement, on-site construction and on-site closure

attic steel structure installation

1. Measure and set out according to the attic design drawings, locate and set out on site, determine the size of the embedded position and the range of plastering positions that need to be removed

2. Anchor bolt embedded parts are fixed on the original structure with chemical bolts. The structural surface of the embedded steel plate at the end of the main steel beam shall be polished and leveled, and other irregularities shall be handled according to the situation. According to the design position of embedded parts, stagger the original structural reinforcement, drill bolt holes and clean them. Chemical bolts can be implanted only after the drill hole is inspected to be qualified, and the bolts cannot be moved until the chemical agent is completely solidified

3. Embedded installation locate and drill holes on the embedded steel plate and angle steel (section steel) according to the actual chemical bolt hole position, and then install the embedded steel plate. Other embedded parts shall be installed together with the cross brace between beams

4. After the antirust treatment materials arrive at the site, all steel structure materials shall be derusted, painted with antirust paint for protection and dried

5. Re measure the size of the profile steel on the processing site, accurately process the profile steel, and remove the paint film at the welding position, so that it can be accurately installed in place at one time and ensure the welding quality

7. According to the design drawing, the main steel beam is welded with the transverse brace between the beams

8. The floor installation takes OSB board as an example. According to the structural design of the attic floor, the structural board (such as OSB board) is successively fixed on the steel structure with self tapping screws, and paved with sound insulation cotton (PAD), and the surface plate is fixed on the lower structural board with self tapping screws. The surface plate and the lower structural plate are staggered and overlapped. About 3mm joints should be left between plates, and the gaps should be filled

five advantages of steel structure buildings

first, light weight and high strength. The weight of houses built with steel structure is about half of that of reinforced concrete houses, and the use area is about 4% higher than that of reinforced concrete houses

second, it has good seismic performance and better ductility than reinforced concrete. According to the post earthquake investigation results at home and abroad, the number of steel structure buildings collapsed is the least. Taiwan Province of China has realized this since the earthquake on September 21st, 1999, so steel structure buildings have increased rapidly

III. steel structural members, wallboards and related components are manufactured in the factory, which reduces the on-site workload, shortens the construction period, and meets the requirements of industrialization

IV. steel structural members are manufactured in the factory with reliable quality, accurate size, convenient installation, and easy to cooperate with relevant parts

v. steel can be recycled, with less environmental pollution during construction and demolition, which is in line with the national policy of promoting industrialization and developing energy-saving and Land-saving Housing

several points that should be paid attention to in the steel structure attic

1. Before making the attic, it is best to find several professional attic companies to design the design scheme of the steel structure of the attic

2. Determine the material used for the steel structure of the attic (the span is more than 3.5 meters. It is best to use national standard steel). Some unprofessional attic companies recommend that the owner use square steel (square steel cannot be completely rustproof inside and outside, is easy to oxidize, and its thickness is relatively thin). Channel steel or I-beam should be used correctly

3. Houses with frame structure are hollow bricks. When making attics, channel steel should be used as a beam in the wall. If only a hole is dug in the wall, channel steel should be erected Hollow bricks are subjected to single force It's easy to fall

4. Attic steel structure channel steel. The maximum dimension of angle steel laying is 610mm*610mm, which is based on blockboard 1 22 meters *2 44m. Otherwise, a lot of boards will be wasted

5. The welding of channel steel and angle steel must be on the same plane. When welding under the channel steel, the load will be not solid when placing the plate, and it must be leveled after welding

6. It is best to use socket welding at the joint of channel steel and channel steel

7. Rust prevention is also very important. The rigid structure is wrapped inside, which is easy to absorb moisture and difficult to disperse moisture (especially in the attic above the bathroom). It is best to remove rust before making
