AI Technical Summary
The existing three-section waterproofing screw rod is susceptible to external interference after installation, which can cause the threaded connection between the cone connector and the external screw rod to loosen, resulting in the external screw rod falling off. This affects the accuracy of concrete wall pouring and creates potential leakage hazards, reducing the reliability of the waterproofing project.
The system employs a three-section leak-proof water-stop screw rod. Through the design of the stainless steel body, combined with the symmetrical arrangement and welding fixation of the auxiliary mechanism, the positioning column cooperates with the circular groove of the wall, the damping plate structure restricts the rotation of the external screw rod, and the magnetic plate design enables the auxiliary mechanism to be quickly received and accommodated, thereby enhancing the connection stability and waterproofness.
It significantly improves the stability and waterproofing of the water-stop screw rod, prevents the external screw rod from loosening due to external interference during the pouring process, ensures the fixing effect of the formwork and construction efficiency, and improves the reliability and practicality of the waterproofing project.
