Professional production:
Prestressed Anchorage/Mining Anchorage/Slope Foundation Pit Support Anchorage/Bridge Anchorage
Executive standard: GB/T14370-20
1. Application:
Mainly used in highway bridges, railway bridges, urban interchanges, urban light rails, high-rise buildings, water conservancy and hydropower dams, port terminals, rock mass slope protection anchoring, foundation reinforcement, warehouse workshops, bridges and buildings reinforcement, pre-tensioned beam field construction, external Prestressing engineering, etc.
2. The specifications of anchors commonly used in China are as follows:
M15-N anchor. M stands for anchorage; 15 stands for the steel strand with a specification of 15.2mm, (15.2mm steel strand with a strength of 1860MPa grade commonly used in our country); N refers to the steel strand to be worn number of wires.
1. Round anchor
Specifications and models are expressed as: YJM15-N/ YM15-N/ M15-N / OVM15-N; this type of anchor has good self-anchoring performance. Tensioning generally uses a piercing jack.
The above picture is M15-5 (15 means using steel strand 1*7-15.2mm, 5 means wearing 5 15.2mm steel strands in the anchor) GB commonly used four-piece anchor set (Anchor Head, Wedges, Anchor bearing plate, Spiral reinforcement)
Highway bridges, railway bridges, urban interchanges, urban light rails, high-rise buildings, water conservancy and hydropower dams, ports, and four-piece sets of national standard anchors are usually used.
Rock mass slope protection anchoring, foundation reinforcement, slope support reinforcement, usually use four-piece sets of heterosexual anchors (made according to construction drawings).
2. Flat anchor
The above picture is BM15-4 (15 means using steel strand 1*7-15.2mm, 4 means using 5 15.2mm steel strands in the anchor) three-piece set of commonly used anchors (Anchor Head, Wedges, Anchor bearing plate)
3. Mine anchors
Mine steel strands and anchors are devices used in coal mine support, in order to maintain the tensile force of prestressed tendons to support the rock mass of the coal mine roadway.
Specifications and models of anchors: KM15 series, KM18 series anchors, KM22 series
