LBT-1122 Geosynthetic Material Joint and Seam Wide-Strip Tensile Test Fixture (New Standard)

Description

Product Introduction:

Technical Specifications:

Name	Geosynthetic Wide-Strip Tensile Test Fixture
Material	45# steel + P20 chromium-nickel alloy steel
Surface treatment	Sandblasting nickel plating
Scope of Use	Tensile properties of geosynthetic joints and seams, applicable to mesh‑type geosynthetics and to sheet‑type geosynthetics other than geomembranes, including geotextiles, geosynthetic composites, geogrids, and others.
Fixture Specifications	The clamping plate can accommodate specimens up to 10 mm thick, with dimensions of 50 mm high by 210 mm wide and a corrugated surface. The plate features an R3‑type large‑wave tooth profile. Each fixture weighs 8 kg. Reference: GB/T 15788-2017, JTG 3460-2026
Optional connector (customizable)	Optional Type A or Type B connector: A connector, shaft outer diameter 20 mm, length 30 mm (with lock nut) B‑type connector: inner bore 20 mm, depth 30 mm; pin hole diameter 10 mm, with the center of the pin hole located at the connector. End-face distance: 14.5 mm.
Note	When no connector is used, the clamp body has an M12 internal thread.
Experimental Procedure	Adjust the gauge length between the two grips to 100 mm ± 3 mm, plus the seam or joint width, except for geogrids and geonets. Set the testing machine’s crosshead speed so that the specimen is stretched at a rate of (20% ± 5%) of the gauge length per minute.
