Professional Bridge Tensioning Equipment Prestressed Anchor Round Porous
Technical parameter of Bridge Tensioning Equipment Prestressed Anchor
Introduction of Bridge Tensioning Equipment Prestressed Anchor
Anchorage refers to a permanent anchoring device used in
prestressed concrete. It is an anchoring tool in a post-tensioned
structure or component to maintain the tension of the prestressed
tendon and transmit it to the interior of the concrete. It is also
called a prestressed anchor. Tool.
Anchors can be divided into two categories according to the type of
use:
(a): An anchoring tool that is installed at the end of the
prestressing tendon and can always keep the prestressing tendon in
an anchored state during the tensioning process of the prestressing
tendon.
Tension end anchorages can also be divided into clip-type
anchorages (YJM) for tensioning prestressed steel strands, steel
tapered anchors (GZM) for tensioning high-strength steel wires,
Pierhead anchors (DM) for tensioning high-strength steel wire after
heading, nut (YGM) for tensioning finish-rolled rebar, cold-cast
heading anchor (LMZ) for tensioning multi-strand parallel wire
bundles, etc. Many types.
(b) Fixed end anchorage: An anchorage installed at the end of the
prestressed tendon, usually embedded in concrete and not used for
tension, also known as squeeze anchor or P anchor.
Application fields of Post-tensioned Prestressed Anchor
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, tunnel mine roof anchor roof, prestressed grid,
subway, large buildings, halls, Warehouse workshop, tower building,
heavy lifting, sliding film intermittent propulsion,
bridge, and tunnel jacking, large containers and ships,
sleepers, replacement of bridge supports, bridge and building
reinforcement, steel reinforcement works, anti-magnetic and
anti-corrosion works (fiber anchors) ), carbon fiber reinforcement,
pre-tensioned beam field construction, external prestressing
engineering, stay cables, suspension cables, etc.
General anchorage construction and installation method
The general anchorage construction and installation method are to
put a small number of explosives at the bottom of the hole, expand
it into a spherical shape after several anchorage constructions and
installations, and finally put the explosives into the anchorage
construction and installation. Compared with the hole anchorage
construction and installation method, this method has the
advantages of good anchorage construction and installation effect,
high work efficiency, fast progress, and low consumption of
explosives. This method is often used in the construction and
installation of short pile anchors for shallow foundations.
Warm tips
1. The anchors should be kept properly, and there should be no
rust, water, and other sundries in use.
2. Apply lubricant on the outer surface of the tool clip and the
inner surface of the taper hole of the anchor plate before use, and
often remove the debris on the surface of the clip.
3. Safety measures should be taken during tensioning, and no one
can stand after the tensioning jack.
4. The anchor system should be used together and cannot be mixed
with other systems.
