The adhesive mold reamed anchor bolt uses the reamer wall of the hole bottom and lock button to form the lock button effect. At the same time, fitting with the anchor adhesive, they complete the anchor together. The adhesive mold reamed anchor bolt has both the advantage of mechanical anchor and the integration of the seismic resistance and impact resistance of anchor adhesive. It has a high carrying capacity. In recent days there are some letters from the design institutes. When they design the drawings, they should know the value of the reamed anchor bolt. But when they look at the pictures album of Mankate’s adhesive mold reamed anchor bolt, they have found that in it there are design values and standard values. So what is the difference between these two? We have collected some questions and today let’s talk about them.
Q: NJMKT-H-type anchor and NJMKT-Z-type anchor look like the same from the bearing capacity. What is the difference between these two?
A: The Z-type and H-type of the adhesive mold reamed anchor bolt is defined from the way of reaming. Z represents self-reamed and H represents after-reamed.
Q: The notes under the table refer to the material sub-coefficient and the overall sub-coefficient. The standard value of the tensile different to the design value is 1.8 times, and the shear phase is 1.2 times. While the phase between the design value and the recommended value is 1.4 times. How are these coefficients specified, and how to use these values? In addition, what is the relationship between them and the experimental test value?
A: When the designers select the type, they can’t only choose from the force data, but also from the structural security. If it is important structure, then choose H-type. As for the coefficients of standard values and design values, they can not be used as a basis for the design. They need to be checked. If you give the load value, Nanjing Mankate Technology Department can help you calculate them.
Q: What are the meanings of the thickness of anchorage and the total length of the screw in the table?
A: Anchorage thickness refers to the thickness of the embedded parts. And the total length of the anchor is the actual length of the bolt.
