Introducing the groundbreaking new three-stage waterproof bolt, a game-changer in building construction waterproofing projects. This innovative bolt showcases remarkable improvements in both structure and function over traditional waterproof bolts. Let's delve into its intricate structural composition, sophisticated working principle, undeniable advantages and unique characteristics, and the diverse range of application scenarios it caters to:
• Structural composition
The essential middle water stop section: Serving as the core component of the water stop, this section is typically cylindrical, graced with a circular water stop plate meticulously welded in its center. This fully welded plate to the bolt effectively obstructs the seepage channels created by groundwater navigating through the bolt, significantly boosting the waterproofing efficacy.
Ingenious two-end screw sections: These sections connect seamlessly to the middle water stop section via connecting components such as plastic cones or threaded sleeves. They play a critical role in affixing and dismantling formwork. Once concrete pouring reaches the requisite strength, these sections can be effortlessly dismantled, recycled, and reused.
Versatile connecting components: Predominantly crafted as conical plastic sleeves, these components not only connect but also create conical grooves post-removal of the screw, facilitating subsequent groove sealing treatments. The intuitive threaded sleeve engages through threading, eliminating the need for additional groove treatment upon disassembly.
• Working principle
In the formwork installation stage, the three-stage water stop bolt expertly threads through both sides of the formwork and the reinforced concrete wall, securing the formwork and bolt at both ends with nuts. This ensures exceptional formwork stability and prepares the space for concrete pouring. Post-concrete pouring, once strength criteria are met, the screws and formwork at both ends are removed, leaving the middle water stop section in the wall. This section acts as a permanent barrier against water seepage, achieving a superior waterproofing outcome.
• Advantages and Characteristics
Maximized cost savings: The ingenious reusability of screws at both ends curtails steel consumption, significantly reducing engineering costs.
Effortless construction: Seamlessly simplifies the traditionally tedious installation and removal processes of water stop bolts, expediting construction timelines and enhancing operational productivity.
Unmatched waterproof efficacy: The middle waterstop integrates seamlessly with concrete, adeptly averting groundwater leakage and dramatically elevating waterproof performance to new heights.
Enhanced wall aesthetics: Post-demolition, the wall surface is skillfully leveled, minimizing repair tasks and ensuring superior wall appearance quality.
• Application scenarios
This versatile solution finds extensive use in the waterproofing of underground engineering marvels. Ideal for reinforced concrete structures necessitating waterproofing for basement exterior walls, water tanks, tunnels, culverts, and more, it effectively counters groundwater pressure and infiltration, safeguarding the integrity of waterproofing efforts and the structural safety of projects.
