Protruding latch lock bolt

Protruding latch lock bolt

Solving construction challenges of lining concrete caused by protrusions! Introducing lock bolts with special head fixing materials.

The "Protrusion-less Lock Bolt" is a product that has reduced the protrusion from the sprayed concrete surface, which was approximately 3 cm with conventional lock bolts, to nearly zero. By using this product, it is possible to prevent issues related to the protrusion, such as restraint (cracking of the lining concrete) and damage to waterproof sheets during pouring, as well as the occurrence of voids, leading to improved concrete quality. Additionally, for tightening and removing the nuts, there are four tightening holes provided, making it easy to perform these tasks with a dedicated ratchet wrench. 【Features】 - The washer is circular and has beveled edges, preventing damage to the waterproof sheet from corners. - Installation of the lock bolt cover, which was previously necessary, is no longer required. - For tightening and removing the nuts, there are four tightening holes provided, making it easy to perform these tasks with a dedicated ratchet wrench. - In the back-smooth type tunnel lining method, the fluidity and filling ability of the filling mortar are improved. *For more details, please refer to the PDF document or feel free to contact us.
