Characteristics
There is no expansion stress, and it is suitable for all kinds of concrete base materials.
There is installation of small edging and small spacing.
There is high bearing capacity, earthquake resistance and fatigue resistance. lt is safe and reliable.
lt is suitable for the environment in which other anchorage can not satisfy.
It has special reaming drill and fast reaming. And it is convenient to install.
There is built-in lock key expansion. And it can be embedded in the pre-reaming cavity.
t can show the perfect lock key effect.
When the buried depth is insufficient, the force can be checked according to the specification.
It performs well under long-term load, cyclic load and seismic load.

How to install undercut mechanical anchor?
1.Use ordinary impact drll mounted on the corresponding ciameter of the drll,according to the anchor size. When drling, the depth should be based onthe specific type and specification of the anchor bolt, the vertcality buried plate aperture and the maximum clearance are refered to the specification JGJ145-2013;

2. Use the pneumatic pump to clean the hole, and the hole must be cleaned;

3. Use special drill for reaming;

4. Clean the hole again with a brush and a air pump;

5.a Preset td pe: before instellationd tighten each part of the anchor bolt and ensure that each part of the anchor bolt is not loosed and the lock ked is not open.Then use a hammer to hit the speciel tool (installation tool)d and push the anchor bolt into the hole until the end surface of the casing is fush with the plane of the concrete base material.
b Penetration tdpe: before installationed tighten each part of the anchor bolt and ensure that each part of the anchor bolt is not loosed and the lock ked is open. Then use a hammer to hit the special tool (intllation tool)d and push the anchor bot into the hole until the ditance between the end surface the casing and the concrete base surface is equal to the thickness of the buried plate.

6. Apply torque to the nut with toroue wrench to the given toroue (the range of toroue wrench depends on the type of anchor bol),and test the desian valueof anchor bot with puler: after the desian value is reached the subseouent constructon (5000 sets a roup, 6 sets/groun. And t wll be calculated as 5000sets, when it is less than 5000)

7. Loose the nut on the anchor bolt. and install the buried plate and fix it. And then use a torsion wrench to tiahten it

1. For products not listed in the table, please reter to "GJ145-2013 Anchoring Technical Specification for ConcreteStructure" to check the calculation method of bearing capacity limit state and get the corresponding data.For specific scheme, please consult the Technical Department of Nanjing Mankate Science & Technology Co, Ltd.
2. The data in the table is applicable to: proper installation, no spacing, no spacing effect, minimum substrate thickness
3. The data in the table is based on C20/C25 material concrete. The influence coefficient of concrete strength should beadded according to the specification for the change of base material grade (following the requirements of the designdrawing and the suggestions of the technical department)
4. The data in the table marked with * are controlled under the condition of steel failure
5. The design load includes the factor of material safety.
6.The basic data in the table are derived according to ETAG001 2013 edition and its appendix, The partial coefficient of load application should be selected according to GB50009 Code for Load of Building Structures.
