How to deal with the abandoned special-shaped steel mold

Profiled steel formwork is a steel formwork used for concrete pouring. Special-shaped steel formwork can replace wood formwork, significantly reducing the removal of pore water pressure and air bubbles in concrete pressure by traditional sealed formwork such as wood, plywood or steel plate. After concrete pouring, the special-shaped steel formwork structure forms an ideal rough interface. Rough machining is not required to proceed to the next process.

Profiled steel forms can be placed before or after reinforcement installation. If it is placed before installing the steel bars, it is convenient and easy to place and install; it can intuitively monitor the concrete pouring process, thereby reducing the risk of porosity and honeycomb structure.

Special-shaped steel mold repair, transformation, scrap how to deal with? Let's take a look.

1. Under normal use, the special-shaped steel formwork department shall inspect and evaluate the main steel formwork of the bridge every quarter.

2. After the inspection is completed, the bridge steel formwork that needs to be repaired (or modified) should be removed, stacked, and marked in a separate area. The management personnel of the special-shaped steel form shall fill in the application form and report to the project management department for approval.

3, the project management department according to the safety and quality supervision department, material management department to provide the need to transform the special-shaped steel mold proposed transformation plan, reported to the project management department to organize the implementation, approved by the chief engineer.

4. If the special-shaped steel mold is damaged or corroded seriously and loses its repair ability, the manager of the user department shall fill in the Application Form for Scrapping Special-shaped Steel Mold and report it to the Engineering Management Department for handling.

5. The Engineering Management Department organizes the Material Management Department and the Safety and Quality Supervision Department to identify the discarded special-shaped steel molds. The engineering management department issues the notice of scrap of special-shaped steel formwork. The material management department and the department using the special-shaped steel mold shall clearly annotate and write off the special-shaped steel mold, and indicate the date of scrapping.

6, scrap special-shaped steel mold should be dealt with within a time limit, too late should be stacked separately.

Before the special-shaped steel molds are put into use, the safety and quality supervision department shall organize re-inspection, and the unqualified products shall be returned to the manufacturing department within a time limit. The spare special-shaped steel formwork shall pass the inspection before it can be put into use again. In addition, in the process of use, the full-time inspector of the safety and quality supervision department is responsible for the quality supervision of the installation and disassembly of the special-shaped steel mold.
