Anchor bolt is a kind of fixed parts used in mining and tunnel construction, etc., can also be used for equipment installation, highway, bridge and guardrail installation, building reinforcement and other occasions, anchor bolt has many types and specifications, but there is one in the anchor bolt.
The new type of anchor bolt is more powerful and stronger than the ordinary anchor bolt, which is the chemical anchor.
Chemical anchor bolt is a new type of anchoring material, mainly composed of chemical agents and metal screws, the chemical agent of chemical anchor bolt is mainly composed of corrosion-resistant vinyl resin, quartz particles and curing agent as the main raw materials, also known as chemical bolts.
Chemical anchor bolts have good seismic and tensile properties, and are mainly used for fixing or reinforcing curtain wall structures, installation machines, steel structure guardrails, and windows.
The function of the anchor bolt is to embed the anchoring components in the substrate (rock, concrete, etc.), and form a reliable connection with the substrate, so that the substrate can effectively hold the anchor components and form a whole and common force.
Anchor bolts are often used in engineering construction, in the past, people like to use anchor anchors, expansion anchors, etc., but now people prefer to use chemical bolts. Chemical anchor refers to the fact that it is not easy to be disturbed by the outside world, it has acid and alkali resistance, low temperature resistance,
The new type of anchor bolt with aging resistance, good heat resistance, good flame retardant performance and good welding resistance is composed of four parts, the most important of which is the screw and chemical hose.
Chemical anchor bolt is another new type of anchor bolt after the expansion anchor, which is through a special chemical adhesive to fix multiple glue joints of the bolt in the borehole to achieve the anchorage effect of the fixing.
The working principle of the chemical anchor bolt is also very simple, first of all, according to the engineering requirements, punch holes in the corresponding position in the substrate (rock, concrete, etc.), and then use a special air cylinder, brush or compressed air machine to clean the dust in the borehole, and put the chemical bottle
Into the drilled hole, which is also different from the ordinary anchor bolt, and then screw the screw into the hole to mash the internal agent to make it expand, and then fill the entire hole, so that the agent, anchor bolt and substrate are all mixed together to form a whole, to achieve the effect of anchoring.
So what if the substrate or rock inside cracks? Don't worry, some chemical anchors have a double-layer structure inside, it can slide, if the rock inside is cracked, it will push the sliding rod outward, and the workers will
The degree of rock cracking can be judged by the distance the slide bar slides, so that safety can be better guaranteed. The emergence of each new anchor bolt is born along with problems in engineering applications, such as in order to solve the corrosion resistance of anchor bolts.
People have invented chemical anchors, small anchors play an important role in bridges, highways or engineering tunnels, because of this, many countries in the world will anchor bolts as key technologies and important materials, it can be said that anchor bolts though
It is small, but it has made a great contribution and will play an increasingly important role in the field of engineering in the future.
