Summary： The principle and function of the construction of the epoxy anchoring and chemical anchors are similar. What is the difference between the two? Why do more customers choose the epoxy anchoring?

The construction principle and function of the epoxy anchoring and chemical anchor are similar. What is the difference between them?

(1) Which reinforcement effect is better?

1 epxoy anchoring

It is drilled on the concrete, wall rock and other substrates, then injected into the hummer, and then inserted into the steel or profile.

After the glue is solidified, the steel bar and the substrate are bonded together, which is a commonly used construction engineering technology in the reinforcement and reinforcement industry.

2 chemical anchor

The bolts and the internally threaded tubes are cemented and fixed in the bore of the concrete substrate, and a component for anchoring the connected members is realized by the adhesion and blocking action of the adhesive and the screw machine binder and the concrete hole wall.

The difference between chemical anchor and epxoy anchoring

1, specifications and standards

The diameter and length of the chemical anchors have certain specifications; the planting reinforcement can achieve complete on-site customization.

2, functional role

Chemical anchors are mostly used for the connection of steel structures to concrete; planting tendons are often used for the connection between concrete members.

3. Design method

Chemical anchor bolts have a more perfect calculation theory of pulling, shearing and considering group anchor effect; after the planting bar is to meet the spacing and depth of the planting bar, it is considered that the material and the limit strength are achieved.

4, depth

A certain number of chemical anchors, the more sparse the arrangement, the better the compression zone is better than the tension zone; the deeper the better the planting bar meets a certain spacing.

5, performance requirements

       In terms of the scope of use, the performance parameters are also different. The main requirement parameters of 悍马植筋胶 are the tensile strength of ribbed steel bars (or full screw) and concrete under the conditions of splitting tensile strength and constrained drawing. Splitting tensile strength refers to the strength of plastic deformation until the source of cracking, the maximum tensile force that the material can resist. These two parameters mainly reflect the anchoring force of the rubber.
