Expansion device "Metal Garg Joint NLt-FLSRFD type"
NLt-FLSRFD type (suitable for snow load compression force of 10kN)
Vertical (one-sided) tooth structure, load-supporting type, non-drainage structure! The maximum floor slab gap applicable is large and economical.
The "Metal Garge Joint NLt-FLSRFD Type" is a joint designed to withstand a compressive force of 10 kN in areas with heavy snowfall. The main components are shaped steel and stud welding, based on the long-standing proven performance of the NL-FL type, which is also rated for a compressive force of 10 kN. Additionally, it allows for easy concrete pouring and ensures tight compaction, enabling a strong integration between the joint body and the floor slab. 【Features】 ■ Structural Characteristics... Vertical (one-sided) double-sided tooth structure, load-supporting type, non-drainage structure / reverse L-shaped integral structure of the supporting beam ■ Durability... The main components are shaped steel and stud welding, based on the long-standing proven performance of the NL-FL type, rated for a compressive force of 10 kN ■ Mobility... The joint tooth gap is small, ensuring good mobility ■ Water Resistance... The water stop section is filled with high-quality, highly waterproof elastic sealing material (passed water stop performance tests as per NEXCO test method 438) ■ Noise Reduction... The tooth structure reduces tire impact, and the use of soundproofing fillers effectively reduces noise *For more details, please download the PDF or feel free to contact us.

Delivery Time
Applications/Examples of results
■Roadway section (PC bridge, RC bridge, steel bridge, prebeam bridge) ■Snowy cold regions ■Vertical joints, horizontal joints ■New installation, repair ■Replacement from steel finger joints/steel slide joints 【Other Features】 ■Workability... Easy to handle weight allows for installation as planned; concrete pouring is easy, enabling tight compaction for strong integration between the joint body and the deck slab; no special formwork required for installation, reducing construction time ■Repairability... High durability due to a structure that encapsulates the water stop section with a steel surface, resulting in a long repair cycle ■Expandability... Ground cover joints (NTE) that integrate the roadway section and ground cover section are available; zinc thermal spray types and other options for salt damage and rust prevention are available; a "double water stop unit" with a continuous secondary water stop structure can be installed as preventive maintenance against primary water stop function decline; snow removal guide plates "Super Rib" (SRS) are standard equipment for snowy areas; processing and anti-slip treatment on surface steel materials can be done depending on the installation location ■Economy... Large applicable maximum deck slab gap volume is economical; contributes to LCC with excellent total balance
