 There are distinct differences between steel trusses and spatial structures. Spatial structures incorporate spheres (such as bolted spheres and hollow spheres), whereas steel trusses generally do not use spheres, though they may be used in certain applications—for example, at supports or where steel pipes and pipe connections are not suitable. From an engineering perspective, steel trusses have better load-bearing capacity than spatial structures and can span over 100 meters; spatial structures generally do not exceed a span of 100 meters. Steel trusses refer to truss structures made of steel used in industrial and civil buildings for roof structures, crane beams, bridges, and hydraulic gates, among others. Steel trusses are commonly used as primary load-bearing members. Various types of towers, such as mast towers, television towers, and power transmission towers, often employ spatial steel trusses composed of three-sided, four-sided, or multi-sided planar trusses. Spatial struc...

 As environmental awareness continues to grow, people are placing higher demands on the environmental performance of traditional coal sheds . To address this issue, innovative steel structures have emerged. Traditional coal sheds often suffer from environmental pollution problems such as coal dust dispersion and exhaust emissions, posing potential threats to the surrounding environment and human health. However, by adopting innovative steel structures, we can construct eco-friendly coal sheds that effectively resolve these environmental pollution issues. First, steel structures offer excellent ventilation. The mesh structure inside the coal shed facilitates air circulation, effectively reducing the accumulation of coal dust. Compared to traditional enclosed coal sheds, mesh-frame coal sheds provide superior ventilation, preventing coal dust from accumulating inside and thereby reducing pollution in the surrounding environment. Second, steel structures enable efficient flue gas trea...

 In the general notes of steel structure construction drawings, have you ever written a line like this: “Drafted, stamped, and issued.” Everything seems to flow smoothly. “For this project, Grade 1 welds shall undergo 100% non-destructive testing, Grade 2 welds shall be subject to 20% sampling inspection, and Grade 3 welds shall undergo visual inspection.” However, if someone were to ask at this moment, “Why must this weld be Grade 1, while that one can be Grade 2? Who exactly determines this ‘grade’?” would your answer still flow so smoothly? This question, though seemingly basic, represents the most fundamental—and yet most easily overlooked—underlying logic in steel structure welding design. The classification of weld quality grades is by no means arbitrary, nor is it a matter of the designer’s “whim.” It is underpinned by a clear, rigorous set of principles, proven through engineering practice, which directly determine the structural safety and service life of the structure. T...

Steel structure workshops, with their fast construction speed, low cost, and good sturdiness, are widely used in manufacturing and warehousing areas. However, in the hot summer, these workshops become sweat-evaporating chambers. Even without a hot production area, the temperature inside a steel structure workshop can be 5 degrees Celsius higher than the outside temperature, and the heat source temperature in the production area often reaches over 40 degrees Celsius. Environmental problems associated with steel structure workshops and sheet metal buildings include: 1. Large area and space make it difficult to find suitable ventilation and cooling equipment. 2. Poor insulation of sheet metal roofs leads to stuffy and hot workshops in summer. The heat generated by machinery in some steel structure workshops and sheet metal buildings accumulates if it cannot be expelled in time, increasing the workshop temperature, making it stuffy, and affecting the workshop environment. To solve the env...

 The roof of a space structure plays an extremely important role in a building—providing shelter from wind and rain and ensuring efficient drainage. Whether in large-span sports halls, exhibition centres, industrial plants or logistics warehouses, a well-designed roof drainage slope is key to ensuring the structure functions properly. If the slope is not properly managed, the consequences can range from minor issues such as water pooling and leaks—which affect the building’s aesthetics and service life—to more serious problems, such as structural safety risks caused by excessive water accumulation and dead loads during heavy snowfall or torrential rain. Therefore, the appropriate management of roof slopes is an aspect of space frame design that cannot be overlooked. So, what are the methods for handling roof slopes in space frame structures? There are generally three methods for handling roof slopes in space frame structures: 1. Installing small columns at the top chord nodes to cr...

Double-laminated glass, also known as laminated glass, is a composite glass product made of two or more sheets of glass with one or more layers of organic polymer interlayer sandwiched between them. After a special high-temperature pre-pressing and high-temperature, high-pressure process, the glass and interlayer are bonded together. Common interlayers include PVB (polyvinyl butyral), SGP (ionic interlayer), EVA (ethylene-vinyl acetate copolymer), and PU (polyurethane). These interlayers are transparent, elastic, have strong adhesion, and good penetration resistance. Even if the glass breaks, the fragments will adhere to the film, and the broken glass surface remains clean and smooth, effectively preventing injuries from shards and falling debris. Production Methods: 1) Film Hot-Pressure Method (Dry Method): The glass and interlayer are stacked in sequence and placed in an autoclave. They are then hot-pressed under specific temperature and pressure conditions to firmly bond the interla...
