Prefabricated Embedded Parts for Building Construction
Prefabricated embedded parts for building construction are components pre-installed (embedded) within concealed works and placed during structural pouring for the purpose of connecting upper structures or installing and fixing equipment foundations.
Classification and Composition
Embedded parts need to be custom-produced according to the building's load-bearing requirements, with specifications and installation positions strictly adhering to the building design's load requirements. They typically consist of anchor bars embedded in concrete and anchor plates exposed on the concrete surface. Based on function, they can be classified as load-bearing embedded parts (bearing structural loads) and structural embedded parts (meeting connection or fixation needs); based on the timing of formation, they can be classified as pre-embedded parts (installed before pouring) and post-installed embedded parts (installed after pouring); based on type, they can be classified as claw-type embedded parts (fixed with multiple anchor bars) and slot-type embedded parts (composed of a channel and T-bolts, offering flexible adjustment and no need for welding).
Application Scenarios
Embedded parts are widely used in building construction. For example, the construction of single-story industrial plants and modern office buildings relies heavily on a large number of embedded parts; in prefabricated buildings, embedded parts are pre-installed before concrete pouring, serving as key anchoring points for subsequent connections to steel structure curtain walls or equipment, enabling modular construction and improving connection accuracy and efficiency. Their anchor bars are firmly welded to steel plates, capable of withstanding dynamic forces such as wind loads and seismic actions, ensuring structural safety.
Construction Process
The construction process for embedded parts includes the following steps:
- Cutting and Processing of Steel Bars and Plates: Cut materials according to design requirements;
- Welding: Adopt new methods such as submerged arc stud welding, using an automatic welding system to achieve automated钢筋 (steel bar) clamping, flux filling and recovery, and the welding process, shortening the construction period and reducing labor intensity;
- Formwork Erection and Installation of Embedded Parts: Use embedded part support devices (including support frames and adjustment positioning devices) to precisely adjust positions;
- Verification of Dimensions and Positions: Check the accuracy of embedded parts against construction drawings;
- Concrete Pouring: Ensure embedded parts are integrated with the structure;
- Curing and Formwork Removal: Ensure concrete strength meets standards;
- Quality Inspection and Repair: Fix deviations or defects to ensure normal function of embedded parts.
Technical Advantages
Slot-type embedded parts, due to their lack of need for welding and flexible adjustment, are suitable for dynamic load scenarios; automatic welding technology improves welding quality and efficiency; embedded part support devices achieve millimeter-level positioning accuracy, significantly enhancing construction reliability.
