In the field of construction, space structure is widely used for its unique advantages, and the installation of embedded parts, as a key link in space structure engineering, plays a decisive role in the quality and stability of the entire project. Today, let us take a deep look at the installation points of embedded parts in space structure engineering.
1.The key role of embedded parts
Embedded parts are components pre-installed in concrete structures, like the “foundation” of buildings. It can closely connect the space structure with the main concrete structure, effectively increase the stability of the structure, and keep the entire grid stable under various external forces. At the same time, embedded parts can also improve the space utilization rate of the structure, provide support and connection functions for the grid, and do not occupy too much concrete structure space. In addition, during construction, installing embedded parts in advance is not only convenient for construction, but also avoids damage and pollution during construction, and ensures construction quality. In later maintenance, as a detachable part, embedded parts are also easy to repair and replace.
2.Selection of embedded parts
According to actual engineering needs and design requirements, the types of embedded parts for space structures are rich and varied. Steel plate embedded parts are often used to bear axial loads and wind loads, and are mostly made of galvanized or stainless steel to prevent rust; steel pipe embedded parts mainly bear lateral loads and thermal expansion and contraction caused by temperature changes, and are usually connected by welding or bolting; angle steel embedded parts are used to reinforce nodes and connect steel plates and concrete structures, and are also connected by welding or bolting; threaded steel embedded parts mainly bear shear and vibration loads, and are connected by threaded connections; steel embedded parts are used to fix steel plates and steel pipes, and are connected by welding or bolting. When selecting embedded parts, it is necessary to comprehensively consider multiple factors such as force characteristics, construction conditions, material properties, and economy to ensure that the selected embedded parts can perfectly adapt to the project requirements.
3.Detailed explanation of installation steps
Make embedded parts: Strictly follow the design drawings and actual size requirements to cut, bend, drill and other processing procedures for the embedded parts. During the processing, the dimensional accuracy and surface quality must be guaranteed to produce embedded parts that meet the requirements.
Check the embedded parts: After the production is completed, the embedded parts are comprehensively inspected and measured to ensure that they meet the design requirements and construction standards. Once any unqualified parts are found, they should be rectified in time.
Positioning and fixing: Accurately determine the position of the embedded parts on the concrete structure, and then use special tools to firmly fix them in the predetermined position. Be careful when fixing to avoid damaging the concrete structure or loosening the embedded parts.
Welding and bolt connection: For embedded parts that need to be welded, the welding process assessment should be carried out according to the design requirements, and welding can be carried out after the assessment is qualified; for embedded parts that need to be bolted, appropriate bolts and washers should be selected according to the design requirements, and they should be installed strictly in accordance with the construction specifications.
Inspection and acceptance: After the installation is completed, the embedded parts are fully inspected, including size, position, connection, etc. If any problems are found, they should be rectified in time. After the inspection is qualified, they can be accepted.
4.Installation precautions
During the construction process, it is necessary to strictly follow the design requirements and construction standards to ensure the quality and safety of the embedded parts. When making embedded parts, it is necessary to control the selection of materials and processing technology to ensure the quality and performance of embedded parts. During installation, space attention should be paid to avoid damaging the concrete structure or loosening the embedded parts to ensure that they are firm and reliable. At the same time, since many embedded parts are made of steel components, anti-corrosion measures must be taken to prevent rust during the subsequent installation of the spatial structure, which will affect the life of the embedded parts and the stability of the project. Although the installation of embedded parts in spatial structure projects is complicated, as long as we master the key points and strictly follow the specifications, we can lay a solid foundation for the success of the entire space structure project. I hope that today’s content can help relevant practitioners and jointly create more high-quality construction projects.
