  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...

Spherical grid structures are often used in various locations, such as waiting rooms, stadiums, and coal sheds.   Spherical grid structures typically come in various shapes, including triangles, rhombuses, and hexagons. Therefore, ensuring ease of installation is crucial during construction. The grid frames must be connected and welded together using rods to secure them. Precautions for Spherical Grid Construction: 1. Pay attention to the grid structure itself. Generally speaking, grids come in various shapes, such as triangles, rhombuses, and hexagons. The specific shape to use, as well as the need for more specialized structures, are matters that the fabricator needs to discuss with the client. 2. It is important to note that the fabricator must be mindful of time constraints during grid construction. Generally speaking, delays in grid erection will result in not only a loss of overtime pay, but also a loss of time expense to the employer. Therefore, time is a crucial considerat...

Color steel plates may have a variety of quality problems during production and use, which not only affect their appearance, but also their performance and service life. The following are some common quality problems of color steel plates and their causes: Coating problems 1. Coating (1) Uneven coating problem. During production, the coating thickness on the surface of the color steel plate will be inconsistent, and some areas will be too thick or too thin. This is usually caused by a malfunction of the coating equipment, improper control of the paint flow, or unstable movement speed of the spray gun. (2) Poor coating adhesion problem. The coating is easy to peel off and peel, and the bonding with the substrate is not strong enough. The root cause is that the surface pretreatment of the substrate is not thorough, there are oil stains or impurities, or the coating formula design is unreasonable. (3) Missing coating is also common in production. Local areas on the surface of the color s...

Spatial structures are widely used in large-span buildings due to their advantages such as reasonable spatial force, light weight and high rigidity. 1. Pre-welding preparation should be meticulous (1) Material quality control The quality of materials such as steel, welding rods, welding wires and flux is the basis. The quality certification documents must be strictly reviewed to ensure that their varieties, specifications and performance are consistent with the design and relevant standards. For example, the Q235 and Q355 steels commonly used in grids must ensure that their mechanical properties such as yield strength and tensile strength meet the standards. The type of welding rod must match the parent material. For example, when welding Q235 steel, E43 series welding rods can be used. At the same time, the material should be inspected for appearance. There should be no defects such as cracks and interlayers on the surface of the steel, and the welding rods and welding wires should n...

  1. Definition of Snow Load Snow load refers to the calculated snow pressure acting on the roof surfaces of buildings or structures, typically representing a spontaneous meteorological load formed by accumulated snow. The magnitude of snow load primarily depends on regional snowfall amounts derived from meteorological data, roof configurations, building geometric dimensions, and normal building usage conditions. In short, snow load is a critical factor in architectural design to ensure structural safety and stability under snow accumulation conditions. 2. Factors Affecting Snow Load Snow load significantly impacts building design across different regions, primarily through the following aspects: (1) Geographic Location and Climate Conditions: Snow load levels vary by region, requiring design parameters to be determined based on local climate and topography. For instance, high-altitude areas and mountainous regions typically experience heavier snow loads, while low-altitude areas a...

  In the installation process of space structures , the aerial bulk method plays an important role in all kinds of construction projects due to its unique adaptability. However, this method requires very high control of the construction process, and many details need extra attention. 1. Pre-construction preparation (1) Accurate measurement and positioning: before installation, the measurement of the foundation must be accurate. The axis, elevation and positional deviation of the pre-buried parts of the foundation may affect the precision of the net frame installation. It is necessary to use high-precision measuring instruments to carry out comprehensive testing of the foundation to ensure that the indicators meet the design requirements. For example, the elevation deviation of the pre-embedded parts should be controlled within a very small range, otherwise it will lead to poor connection of the net frame rods and affect the overall structural stability. (2) Material and equipment ...
