Definition of Anchor Head
Anchor Head is the key part of bearing the prestressing
tension. The head anchorage is made by Cr*0 alloy steel. It
includes round anchorage and flat anchorage.
Prestressing force anchorage
YJM Tensioning System is a complated, independent building measure
researched, and developed by TianJin ZhenHua Prestressing Force
Technology Co. Ltd. It has been widely adopted by modern
construction,especially used in pre-tension or post-tension for
concrete constructions and building materials.
YM Series products are composed of tensioning anchor,holding
anchor,connectors.It can used to lock the steel strand wires
on/under classes of ***0Mpa standard strength,which is usually in
diameters of *2.7mm /*2.9mm/*5.2mm/*5.7mm.
It has been verified by pratice that various type of YM anchor also
can be used for the different kinds of strand wires produced
according to ASTM/BS/JIS/JIG/AS and other international
standards respectively only if its technical parameters shall
mary the related detail materials.
YJM Anchor consists of anchor head, bearing plate, anchor wedge,
spiral reinforcement , plastic or metal corrugated ducts, PC
strands(PC wire bundle).The products can be divided into two types
according to their strand diameters: YJM*3 andYJM*5.
YJM anchorage system has the following features:
YJM anchorage( anchor block ) system can be used to
anchor Φ*2.7mm**5.7mm and strength below ***0Mpa PC
strands.
YJM anchorageis complete in varieties and specifications.Wedge
anchorage can be chosen arbitrarily from ***5 wire PC strand (PC
wire bundle) or according to the specific demands of the
engineering designs. It is an anchorage system featured by its wide
range of the application, easy of the design and simplicity of the
process.
Parameter of YJM *3/*5 Anchorage
INSTRUCTIONS:
1 YM anchorage must be used with YM working wedge, and YM tool
anchorage must be used with YM tool wedge.
2 Work anchorage can\'t substitute for tool anchorage.
3 YM series anchorage must be used with the same specification
located plates of YM.
4 Anchorage must be well keeped to prevent rusting and dirts.
Before installation, rusting and dirts must be cleand to prevent
from damaging the internal thread of wedge which will fill in the
alveolar of wedge when tension.
5 When install anchorage, O Dia of Anchor Head should put in hole
of Anchor Bearing Plate, and the restraing plate must in the same
direction with the hole of tool anchorage, and the strands cannot
be twined around each other and dislocated.
