Introducing the revolutionary three-stage waterproof bolt, a crucial asset in modern building construction projects that demand impeccable waterproofing. This innovative bolt system excels beyond traditional models, offering remarkable enhancements in both structural design and functional capacity. Let's delve into its remarkable features, examining its structural composition, operational mechanics, distinct advantages, and versatile application scenarios:
• Structural Composition
The Middle Water Stop Section: At the heart of the water stop is the cylindrical core, ingeniously designed with a circular water stop plate securely welded at its center. This meticulous welding ensures the ultimate blockage of groundwater seepage along the bolt, greatly amplifying its waterproof efficacy.
Two End Screw Sections: Ingeniously linked to the middle water stop via robust connecting components such as plastic cones or threaded sleeves. These sections are pivotal for the secure fixation and subsequent dismantling of formwork. Once the concrete achieves the desired strength post-pouring, these screws are easily removable and can be efficiently recycled for future use.
Connecting Components: Predominantly composed of conical plastic sleeves, which not only serve their fundamental connecting role but also craft conical grooves post-screw removal, facilitating effortless sealing. The threaded sleeve, moreover, engages seamlessly through threading, eliminating the hassle of additional groove treatment post-disassembly.
• Working Principle
In the meticulous formwork installation phase, the three-stage water stop bolt is expertly threaded through both sides of the formwork, piercing through the reinforced concrete wall at its core. Secured with nuts at both extremities, this arrangement guarantees rock-solid formwork stability, paving the way for flawless concrete pouring. Upon achieving requisite concrete strength, the screws and formwork are effortlessly removed, leaving the middle water stop section entrenched in the wall, perpetually obstructing potential water seepage and delivering unrivaled waterproofing.
• Advantages and Characteristics
Cost-Efficiency: End screws are designed for repeat use, effectively minimizing steel consumption and substantially slashing project costs.
Ease of Construction: Effortlessly simplifies the intricate installation and removal processes inherent in traditional water stop bolts, thereby accelerating project timelines and significantly boosting operational efficiency.
Superior Waterproofing: The middle waterstop achieves a seamless integration with the concrete, providing an impenetrable barrier against groundwater leakage, thus elevating waterproofing performance to unmatched levels.
Pristine Wall Finish: Post-demolition, the wall surface is rendered exquisitely smooth, minimizing repair efforts and guaranteeing optimal aesthetic quality.
• Application Scenarios
This versatile solution is extensively deployed in the waterproofing endeavors of subterranean engineering projects. Ideal for fortified concrete infrastructures necessitating waterproofing—be it basement exterior walls, water tanks, tunnels, or culverts—this system effectively withstands groundwater pressure and infiltration, thereby ensuring impeccable waterproofing quality and structural integrity throughout the project lifecycle.
