Support Accessories: Categorized by Location
What are the support accessories for precast beams? Categorized by location, they include: temporary supports (support rods/screw jacks), end connections (connectors/bearing plates), lifting accessories (lifting points/rigging gear), and reinforcement accessories (ties/diagonal braces).
Industry experts suggest evaluating these accessories based on their specific locations—temporary supports (rods/jacks/bases), end connections (connectors/plates/anchors), lifting accessories (points/rigging/protection), and reinforcement accessories (ties/braces)—to ensure a complete inventory and prevent omissions.
Categorized by Location
- Temporary supports: Support rods/screw jacks (for support);
- End connections: Connectors/bearing plates (for beam ends);
- Lifting accessories: Lifting points/rigging gear (for hoisting);
- Reinforcement accessories: Ties/diagonal braces (for stabilization);
- Checklist by location: Ensure all items are included to prevent omissions.
Key Evaluation Points
First, support configuration: Proper setup of support rods/screw jacks prevents collapse.
Second, end connection setup: Correct installation of connectors/bearing plates prevents poor load distribution.
Third, lifting gear completeness: Having all lifting points and rigging gear ready prevents hoisting hazards.
Fourth, reinforcement configuration: Proper use of ties and diagonal braces prevents tipping or lateral instability.
Pitfall Warnings
First, “insufficient support”: Risk of collapse due to inadequate support configuration.
Second, “weak end connections”: Potential hazards from poor load distribution due to improper end connection setup.
The third point concerns the absence of reinforcement.
There is a risk of tipping if reinforcement measures are not configured.
Trends and Reminders
Support accessories for precast beams are moving towards standardization, characterized by standardized supports (adherence to specifications) and plan verification (data-driven analysis).
Construction units are advised to adopt a strategy of “location-specific inventory, plan-first execution, and proper support placement.”
Comprehensive support ensures safety during hoisting operations.
