Flat Anchorage
Model: BM15-N (N is the number of anchor ring holes)
Number of holes: 2 to 5 holes
Composition: flat anchor head, wedge, flat bearing plate, flat spiral reinforcement
Application: highway bridges, railway bridges, urban interchanges, urban light rails, high-rise buildings, water conservancy and hydropower dams, port terminals, rock mass slope protection.
The shape of the anchor head is flat. The layout of the prestressing tendons is usually horizontal and parallel. The BM stressing flat anchorage is applied for strands of 12.7mm, 15.2mm, and 17.8mm.
It gets rid of the disadvantages of the over-concentrated prestress and large sizes in two directions of the group anchorages. The distribution of the prestress is more reasonable. The thickness of the anchor head can be thinner. It is usually applied in the hogging moments such as the horizontal prestress of the floor of the buildings and bridges and simple support continuous girder.
The BM stressing flat anchorage can work together with YBZ2*2/50 high-pressure oil pump and QYC270 mono strand bottle jack.
