Steel formwork manufacturer: How to deal with and prevent steel formwork running and bursting?

Treatment and preventive measures for steel formwork running and bursting
1、 Problem handling measures
Immediately stop pouring
When mold running or bursting is detected, the concrete pouring should be suspended immediately to avoid the problem from escalating.
Local reinforcement and repair
Support reinforcement: Use wooden blocks, steel pipes, or steel sections to temporarily support the deformed area, supplemented by steel wire ropes or hand pulled hoists for tension.
Leakage treatment: Clean up the leakage and seal the gaps (such as wooden strips and steel plates), re support the formwork, and continue pouring.
Post repair: After hardening, remove the unqualified concrete, chisel the surface and repair it with high-strength grouting material. In severe cases, structural verification is required before reinforcement.
Structural Safety Assessment
Assess the safety of the damaged area by professional engineers and adjust the design plan if necessary.
2、 Preventive measures
Optimization design and verification
Design templates and supports based on concrete lateral pressure (including pumping impact force) to ensure strength, stiffness, and stability.
The special scheme for tall formwork shall be demonstrated by experts, focusing on setting slant support, diagonal bracing and horizontal tie rods.
material quality control
Select qualified steel formwork without deformation or rust, and maintain it regularly.
Use high-quality release agents (such as water-based release agents) to evenly apply and avoid missed brushing.
Standardize the construction process
Installation accuracy: Strictly control the axis and elevation of the template, add adhesive strips or sealant to the joints, and tighten the bolts.
Support system: The foundation is compacted (with wooden or steel plates added), and the support spacing is executed according to the plan. Random dismantling is prohibited.
Pouring control: Layer by layer pouring (each layer ≤ 50cm), avoid tilting on one side, and avoid touching the formwork during vibration.
Monitoring and Inspection
The pouring specialist inspects the deformation of the formwork, monitors the displacement with instruments, and adjusts it in a timely manner.
Acceptance template system, with a focus on checking node reinforcement (such as corners and openings).
Environmental and Personnel Management
Consider the effects of wind load and temperature on concrete pressure and adjust the support design.
Strengthen worker training to ensure operation according to the plan and avoid illegal operations.
3、 Other precautions
Splicing method: Priority should be given to bolted connections, and sealing strips should be used at critical joints.
Emergency preparedness: Prepare reinforcement materials (wooden blocks, steel pipes, steel wire ropes) in advance and develop emergency plans.
Standard basis: Adhere to standards such as the "Technical Code for Safety of Construction Templates" (JGJ162).
Through the above measures, the risks of mold running and bursting can be effectively reduced, ensuring construction quality and safety. The focus is on design rationality, construction standardization, and process monitoring, combined with dynamic adjustment to cope with complex working conditions.
