The advantages of steel structures, such as earthquake resistance, wind resistance, durability, heat insulation, sound insulation, and comfort, are well-known. These advantages rely on the hard work of steel structure builders. After the completion of steel structure construction, safety inspection of the steel structure project is crucial. Here's a detailed introduction to the key points of steel structure inspection, hoping it will be helpful: 1、Construction 1.1 Detection and calculation of the slenderness ratio of steel structural members. Member dimensions can be determined according to the provisions of Section 6.4 of this chapter, and the slenderness ratio of the members should be calculated based on the actual dimensions. 1.2 Connection of steel structure support system,

First, high-quality substrates are used, with increasingly higher requirements for the surface, shape, and dimensional accuracy of the substrates. Outdoor uses include small zinc flower flat hot-dip galvanized steel coils, zinc-free flower flat hot-dip galvanized steel coils, and the currently popular zinc alloy hot-dip coils; indoor uses include electrogalvanized steel coils, film-coated cold-rolled sheets, and aluminum coils. Second, the pretreatment process and pretreatment solution are improved, with fewer equipment and lower costs becoming the mainstream process, constantly improving the stability, corrosion resistance, and environmental performance of the pretreatment solution. Third, the development of new coatings is emphasized, and improvements are made to general polyester, polyvinylidene fluoride (PVDF), and plastic sols to obtain super color reproducibility and resistance.

Green buildings refer to buildings that, throughout their entire life cycle, maximize resource savings (energy, land, water, and materials), protect the environment, reduce pollution, and provide people with healthy, usable, and efficient spaces that coexist harmoniously with nature. Green buildings encompass planning, construction, and operation of solutions that are more efficient, healthier, and more sustainable than traditional solutions throughout all phases of the building lifecycle, while maintaining the same level of comfort and service. China currently has more than 50 billion square meters of existing buildings, while 1.6 to 2 billion square meters of new buildings are constructed each year. More than 95% of buildings in China are...

Steel structure welding specifications: Steel structure fabrication involves processes such as material preparation, assembly, welding, and inspection. Manual arc welding construction process standards are based on the following standards: GB50300-2001 "Unified Standard for Quality Acceptance of Building Construction", GB50205-2001 "Code for Quality Acceptance of Steel Structure Engineering Construction", GB11345 "Methods for Ultrasonic Testing of Steel Welds and Classification of Test Results", GB3323 "Radiographic Testing of Fusion Welded Joints in Steel and Quality Classification", JBJ/T3034.1 "Ultrasonic Testing Method and Quality Classification of Welds in Bolted Spherical Node Steel Trusses". Note: The provided text contains some technical terminology which may require further clarification in the translated context. The original Chinese text is retained for those sections.

There are many things to note during the welding process of steel structures. Once overlooked, it may lead to major mistakes. Today, I have compiled some frequently overlooked matters during steel structure welding for you. Don't take it lightly! Welding construction does not pay attention to the phenomenon of choosing the best voltage and its hazards. Whether it is the bottom, filling, or surfacing, regardless of the size of the bevel, the same arc voltage is selected during welding. This may not reach the required penetration depth and width, resulting in defects such as undercutting, porosity, and spatter. Preventive measures Generally, different arc lengths should be selected for different situations to obtain better welding quality and work efficiency, such as for the bottom layer.

In the modern building market, the rise of steel structure engineering has greatly promoted modern architecture. The reduced application range and construction time of steel structure buildings have been favored by many construction projects. Many factories use steel structure buildings, and public awnings are now also built with steel structures. Therefore, steel structure design has received everyone's attention. Let's talk about the methods of steel structure design below. The probability limit state design method is the basic method of engineering structure design in China and also the basic method of steel structure design. If the structure exceeds a certain specific state, it cannot meet the design requirements.

A steel structure residential project, jointly developed and produced by a certain construction engineering company and Jilin Jianzhu University, officially commenced its main structure hoisting and installation on May 30 in the courtyard of Yu Xin Group in the Changchun Automotive Industry Development Zone. Li Baozheng, the vice general manager of the construction engineering company, introduced that steel structure residential buildings use steel as the load-bearing beams and columns. Its advantages include light weight, high strength, and about half the weight of reinforced concrete residential buildings. It meets the needs of large residential spans, with a usable area about 4% higher than reinforced concrete residential buildings. It also boasts good earthquake resistance, insulation, waterproofing, and sound insulation performance. Steel structure components are factory-produced...

A new building system has the potential to break down the industry boundaries between the real estate, construction, metallurgical, mechanical equipment manufacturing, and national strategic resource industries, combining them into a new industrial system. This is the steel structure building system that is widely favored by industry insiders. This was stated by Fang Hongqiang, President of the Zhejiang Provincial Steel Structure Industry Association and Chief Engineer of Hangzhou Jia Design Group Co., Ltd., in his keynote speech on Steel Structure and Green Building at the 11th National Academic Symposium on Modern Structural Engineering.
