Anchor Bolts Strengthening
Sep 15, 2017

Chemical anchors are a new type of metal fastening materials composed of chemical agents and metal rods. Can be used in various curtain wall, marble dry-hanging construction of the installation of the post, also can be used in equipment installation, highway, bridge guardrail installation; Building reinforcement and renovation, etc. Because of its chemical glass tube filled with flammable and explosive, so manufacturers must be approved by the relevant state departments to production, the whole production process requires strict security measures, and use a completely isolated and staff of the assembly line production. If manual work is not only violated the relevant regulations of the state, it is also very dangerous. Chemical anchor bolt is a new type of following expansion anchor bolt, is through a special chemical adhesive, fix the screw cement concrete base material in drilling, in order to realize the fixed anchor composite parts.


Expansion anchor bolts: anchor bolts that use an expansion piece to squeeze the wall of an anchor hole to form an anchor. Is the use of vertebral body move to opposite of inflation, prompting expansion expansion, and the pressure of bore wall concrete expansion agent, and through the pull-out force of the shear friction effects from a component by fitting the anchoring.

Torque control expansion anchor: pre-drilled with special drilling tools to complete expansion installation by controlling screw torque size

Displacement control type expansion anchor: drilling in advance with a special drill bit to achieve expansion installation through the relative displacement of the sleeve and cone head

Expansion groove anchor: through the hole at the bottom of the concrete cutting reaming, again use reaming after forming pressure on the surface of concrete and anchor inflation to expand the mechanical interlock between, realize to be fitting the anchoring of a component.

Prereaming ordinary anchors: precut grooves through special drilling tools

From expanding special anchor: with special drill hole first, bolt built-in tools, when installation to cutting reaming, reaming, install a complete anka anchor: this is a kind of anchor bolt, abroad to introduce the general import equipment of anchor bolt are the anka anchor, especially European equipment, have an opening at the back of the anchor bolt type metal sleeve, into the foundation, wrenching rib, after opening up the big fixed.

Post-cut anchor bolt: it is a very common expansion bolt in our market, which cannot be fixed by itself and needs to be fixed with the fixed object, mainly its opening sleeve structure limitation.

Anchor bolt: the back of the anchor bolt is open, and the center has a steel nail. When the anchor bolt is inserted into the foundation, it will only need to hit the steel nail, and the steel nail will go down and the opening will be fixed.

The anchor bolt often works with the concrete base to carry the weight and load of the machine to ensure the smooth operation of the machine. The material of the anchor bolt used for concrete structure can be carbon steel, stainless steel or alloy steel, according to the difference of environmental conditions and the requirements of durability, the corresponding varieties should be selected. The performance of anchor bolts shall be in accordance with the relevant provisions of the standard of construction industry of the People's Republic of China.

In the use of concrete pedestal, weathering, severe crack, and uncompacting will lead to loose anchor bolts, which will cause the vibration of the machine to intensify and affect the normal operation of the machine parts. The traditional method of repairing will result in the increase of production downtime, resulting in huge economic losses. In order to solve the problem of bolt loosening, the more effective method of repair abroad is to adopt macromolecule composite material, while the most mature in China is the American jiahua concrete repair material. The anti-impact and compressive strength of the material itself is far greater than that of concrete and has the properties of various chemical media. Its superior tackiness to concrete strength of adhesion is greater than that of concrete itself (concrete would be broken) first, at the same time also adhesion to steel and other rough surface, and fast curing properties, can save the loss caused by production for the enterprise.
