 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...

 Spatial structures have become a widely adopted structural form in recent years. Composed of bolt-ball nodes and seamless steel tubular members, these highly indeterminate structures are assembled using high-strength bolts or welding connections. They are characterized by a low steel-to-span ratio, excellent seismic resistance, short construction cycles, and aesthetic appeal. These structures are extensively utilized in large-span engineering projects, such as sports stadiums, airport terminals, high-speed railway stations, industrial plants, and large-scale storage warehouses. However, during the actual production, fabrication, and installation processes, two key factors can still significantly impact the overall quality of bolt-ball space frame structures. (1) Insufficient Strength of High-Strength Bolts In bolt-ball space frame structures, the strength of the high-strength bolts (which are capable of bearing significantly higher loads compared to standard bolts of the same si...

  1. Main influencing factors (1) Roof load: When the roof load is large, the grid needs to be higher to provide sufficient rigidity and stability. On the contrary, if the roof load is small, the grid height can be relatively low. (2) Span : The span of the grid is another important factor in determining its height. The larger the span, the larger the grid height usually needs to be in order to meet the requirements of rigidity and stability. (3) Plane shape and support conditions: The plane shape (such as circular, square, rectangular, etc.) and support conditions (such as peripheral support, point support, etc.) of the grid will also affect the determination of its height. For example, the height of the grid with a circular or square plane can be smaller, while the height of the grid with a narrow plane needs to be larger due to the obvious unidirectional force transmission. The height of the grid with peripheral support is usually smaller than that of the grid with point suppo...

III.Process control for the installation of bolted ball steel grid structures Bolted Spherical Grid Installation Process Before installing the space frame, installers must be familiar with all the members, ball types, dimensions, and their positions in the drawings. Any deformation of members caused during transportation, storage, or lifting must be corrected. All members and balls must be marked. During installation, they must be carefully checked against the drawings to ensure accuracy before installation. The installation of space frames primarily involves the connection between bolts and spheres. The friction surfaces of components must remain dry. High-strength bolts must be smoothly inserted into the sphere holes, with consistent insertion direction. They must be tightened in two stages, and each set of high-strength bolts must be fully tightened on the same day, with no bolts left untightened. Different installation processes must be adopted for different space frame configurat...

Currently, bolted ball steel grid structures are widely used in cement plant storage shed construction projects due to their aesthetic appearance, structural safety, cost-effectiveness, and short construction cycle. However, there are several key points to note during the fabrication and installation of such grid structures that deserve our close attention. Process control Rod processing Pipe component fabrication is a critical stage in space frame construction where errors can accumulate. The final length of the pipe components is determined by the cutting dimensions of the steel pipes, the thickness of the end plates or cone heads, and the thickness of the weld seams. However, the cutting dimensions of the steel pipes, the thickness of the end plates or cone heads, and the thickness of the weld seams are constrained by the designed length of the pipe components. Excessively large or small weld seams directly affect the connection strength of the pipe components. Therefore, during ac...
