Steel structures have good sealing performance due to their welded structure, which can achieve complete sealing and create high-pressure vessels, large oil tanks, pressure pipelines, etc. with good air tightness and water tightness

The disadvantage of steel structure attic in steel structure engineering is poor sound insulation effect. When wooden boards are used as floor support plates, they are used to seal the upper and lower parts. When people walk on it, the sound produced is loud, so corresponding sound insulation and noise reduction measures need to be taken. The maintenance of steel structure attic is difficult, so it is generally necessary to take corresponding anti-corrosion measures and select high-quality steel components during construction to improve the anti-corrosion performance of steel structure attic. If the steel structure attic needs to be repaired, it is very troublesome to lay wooden boards again, so the steel components of the steel structure attic should be treated with anti-corrosion measures in advance to improve the anti-corrosion performance of the steel structure attic.

Advantages of Steel Pile Tip Engineering Steel Structure: Seismic Resistance: The roofs of low rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel components. After sealing the structural plates and gypsum boards, the light steel components form a very strong "plate rib structure system", which has stronger seismic resistance and resistance to horizontal loads. It is suitable for areas with seismic intensity above 8 degrees. Wind Resistance: Steel structure buildings are lightweight, strong, have good overall rigidity, and have strong deformation ability in Qingyuan steel structures. The self weight of a building is only one-fifth of that of a brick and concrete structure, and it can withstand a hurricane of 70 meters per second, effectively protecting life and property. Durability: The light steel residential structure is entirely composed of cold-formed thin-walled steel components, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet. The steel structure engineering effectively avoids the influence of corrosion of steel plates during construction and use, increasing the service life of light steel components. The structural lifespan can reach 100 years. Thermal insulation: The insulation material used is mainly fiberglass cotton, and Qingyuan steel structure has good insulation effect. The insulation board used for exterior walls effectively avoids the "cold bridge" phenomenon of the wall and achieves better insulation effect. The thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1m. Soundproofing: Soundproofing effect is an important indicator for evaluating residential properties. The windows installed in the light steel system are made of insulated glass, which has good sound insulation effect and can achieve sound insulation of over 40 decibels; The wall composed of light steel keel and insulation material gypsum board can achieve a sound insulation effect of up to 60 decibels. Health: Steel structure engineering dry operation construction reduces the pollution caused by waste to the environment. The steel structure materials of houses can be 100% recycled, and most of other supporting materials can also be recycled, which is in line with current environmental awareness; All materials are green building materials that meet the requirements of the ecological environment and are beneficial to health..

Laser cutting 4. Due to the characteristics of dense joints, no water leakage, and no water absorption in the formwork of the steel plate sitting floor slab of the steel structure company, the slump of the concrete mix ratio of the floor slab and the sand ratio of the steel structure company must be strictly controlled to prevent quality problems such as powder formation and shrinkage cracks caused by low surface strength and sand ratio due to bleeding during the initial setting of the concrete.

The internal structure of laser cut steel is uniform, and the actual working performance of nearly isotropic homogeneous steel structures is in line with the calculation theory. So the reliability of steel structures is high. 3. The mechanization level of steel structure manufacturing and installation is high, and steel structure components are easy to manufacture in factories and assemble on construction sites. Mechanized manufacturing of steel structural components in factories has high precision, high production efficiency, fast assembly speed on construction sites, and short construction period. Steel structure is a type of structure with a high degree of industrialization. 4. Steel structures have good sealing performance due to their welded structure, which can achieve complete sealing and create high-pressure vessels, large oil tanks, pressure pipelines, etc. with good air and water tightness. 5. Steel structures are heat-resistant or not. When the temperature is below 150 ℃, the properties of the steel change very little. Therefore, steel structures are suitable for hot workshops, but when the surface of the structure is exposed to thermal radiation of around 150 ℃, insulation panels should be used for protection. When the temperature is between 300 ℃ and 400 ℃. The strength and elastic modulus of steel both significantly decrease, and the strength of steel tends to zero when the temperature is around 600 ℃.

Special attention should be paid to calculating the shear bond bearing capacity in the production of steel structures. Composite floor slabs are generally controlled by shear bond, and the "High Steel Code" does not include shear bond calculations, which is an oversight. 4. If calculated based on bidirectional plates, the reinforcement at the peak must be configured, and the profiled steel plate has no effect in the direction perpendicular to the ribs. 5. The vast majority of composite floor slabs are one-way slabs, which are very special. For example, the corners may be two-way slabs, because the inclined beams generally have a small span, and without calculation, the same configuration as other parts can basically meet the requirements. 6. The distribution reinforcement on the top of the slab must meet the requirements of GB50010. 7. Whether the rib direction is continuous or hinged at the beam support does not depend on the profiled steel plate, but on the negative bending moment steel bars, and the compression of the profiled steel plate is ignored. The vertical rib direction is generally considered hinged, but anti cracking structural bars should be installed. 8. Composite floor slabs do not require bolts to be designed as composite beams, but there must be certain structural bolts to ensure the integrity of the slab and beam. 9. If designing a composite beam, the secondary beam is generally calculated as a composite beam, and the main beam (frame beam) should not be calculated for bearing capacity as a composite beam, because the frame beam bears repeated loads, and there is no seismic test report for the composite beam - this point is ignored by the specifications. GB50017 is different from GB50010, as GB50017 does not have seismic content. The deflection of the main beam under load can be calculated according to the requirements of composite beams (if it meets the requirements of composite beams)..

Steel structure is a structure mainly composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts, or rivets. Due to its light weight and easy construction, it is widely used in large factories, venues, super high-rise buildings and other fields. The characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation ability, making it particularly suitable for constructing large-span, ultra high, and ultra heavy buildings; The material has good homogeneity and isotropy, and belongs to the ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization. High strength steel should be studied for steel structures to greatly improve their yield point strength; In addition, new types of steel sections need to be rolled, such as H-beams (also known as wide flange steel), T-beams, and profiled steel plates, to meet the needs of large-span structures and super high-rise buildings.

3) Check the material and welding rod specifications (or bolts) of the new steel transported to the construction site, which must be consistent with the evaluation report requirements issued by the laboratory, and must not be changed arbitrarily; When it is necessary to make a change, the laboratory must issue a new evaluation report. Technical management personnel and operation professionals must carefully check whether the new steel material and welding rod specifications (or bolts) used for the specific construction site are consistent with the requirements in the evaluation report (there are three types of welding rods used in the Chipsesde market expansion project, and each type uses a different part: E4315-J427 welding rods are used for the connection between the new steel HPB235 imported from China and the original old steel structural steel; E4303-J422 welding rods are used for connecting new steel imported from China; The connection between locally purchased British standard steel and locally purchased E7018 American standard welding rods must be absolutely accurate, and any behavior that does not meet the requirements must be strictly prohibited. Any mistake will lead to unforeseeable consequences. 4) The rust removal and removal of the corroded oxide layer and slag covering the surface of the original old steel structure must be thoroughly carried out by connecting a dedicated sandblasting rust removal machine with an air compressor. Some severely corroded parts must be manually chiseled or ground with steel chisels, hammers, or grinding wheels. The sand used for sandblasting rust removal is medium fine yellow sand, which needs to be dried in the sun. Due to the high pollution caused by high-altitude operations, it is necessary to set up environmental protection facilities and protect the operators. 5) It is essential to measure various dimensional data and correct deformation of the existing old steel structure. The correction method should be physical, and heating and baking methods should not be used..

1. The cross-sectional dimensions of structural components are relatively small, which can effectively utilize building space, reduce the height of the building, and create a beautiful architectural appearance. 2. The portal frame has good stiffness and light weight, and the beams and columns can be assembled, providing favorable conditions for production, transportation, and installation. 3. The amount of steel used for the roof frame is only 1/5-1/10 of that used for ordinary steel roof frames, making it an economically reliable structural form. The main structure adopts a light steel frame system. The floor panel adopts steel-concrete composite floor slab. The roof panels are made of profiled steel plates, and the wave shaped light steel structure roof beams are lightweight and lively, overcoming the shortcomings of single industrial building shapes and rigid facade shapes. The wall adopts polyurethane wall panels. The integrity of the portal frame roof system can be ensured by purlins and corner braces, thereby reducing the number of roof supports. At the same time, the supports are mostly made of tensioned round steel, which is very lightweight. 2. The beams and columns of portal frames often use variable cross-section members, which can save materials. 3. The members that make up the components are relatively thin, requiring high requirements for production, painting, transportation, and installation. 4. The bending stiffness and torsional stiffness of the components are relatively small, and the overall stiffness of the structure is also relatively flexible. Steel structure truss engineering, especially welded structures, often have defects similar to cracks due to quality and structural reasons such as steel, processing, manufacturing, and welding. Brittle fracture mostly occurs due to the development of these defects leading to unstable crack propagation. When the crack slowly propagates to a certain extent, the fracture expands at a very high speed without any warning before brittle fracture suddenly occurs.

Sports centers, museums, high-rise buildings, and so on are all built with steel structures. So, what are the advantages of steel structures that can be used in many large-scale buildings? The reasons are as follows: 1. Material saving and lightweight. In this regard, compared to buildings built with stone and cement, the stability of the steel structure itself, combined with the decoration inside the building, is very distinctive. It not only eliminates the space occupation of stone due to its volume, but also has good ductility. If steel materials are processed to extend them, they can be used to build even taller or larger buildings, which cannot be compared to stone materials. If it comes to building a high-rise building, whether it consumes more steel or stone, then the answer is beyond doubt. 3. Buildings with strong seismic resistance and steel structures can withstand earthquakes of at least 7 levels, which is basic. However, if they are made of stone, they usually begin to crack at around 5 levels, and the falling stone can easily injure people. Steel structures are different, so this is something that stone cannot compare to..
