The difference between anchor bolt and bolt
There are many concepts in the project that we are more likely to confuse, thinking of similar reinforcement methods, such as anchors and bolts. So what is the anchor? What is the bolt? What are the differences between the two? Let's take a look at it together.
Anchor bolt
An anchor bolt is an anchor assembly product that is anchored to a substrate by a connector, and is divided into a mechanical anchor and a chemical anchor. The anchored anchoring substrate is divided into reinforced concrete, prestressed concrete or plain concrete members; not used as anchoring substrates: freeze-thaw damaged concrete, corrosion-damaged concrete, severely cracked concrete, and uncompacted concrete. Chemical anchors are a new type of metal fastening material that is rented by chemicals and metal rods. The chemical anchor bolt is a new type of anchor bolt after the expansion anchor bolt. The special cement is used to fix the screw in the bore of the concrete substrate to realize the fixed anchoring composite. Chemical anchor bolts are divided into common chemical anchors and special inverted cone chemical anchors.
The mechanical anchor bolt is an anchor bolt that forms an anchor by the friction between the anchor bolt and the anchor hole, and is divided into two types according to the working principle: the bottom anchor bolt and the expansion anchor bolt.
Anchor bolt characteristics: anti-fatigue, anti-aging, anti-corrosion, no creep; strong bonding force, high pulling force, the same effect as pre-buried; wide temperature range, -10 °C ~ 40 °C can be applied; Small pitch, margin, narrow space;
Applicable to all kinds of substrates, concrete, rock plates, aluminum, etc.; non-expanding chemical bonding force, does not damage the substrate; construction is convenient, fast, safe to use, environmentally friendly. Application range: Curtain wall bracket fixing: It can be used for glass, stone, aluminum curtain wall and all kinds of composite curtain wall steel bracket, base, keel fixing; machine equipment fixing; steel structure and concrete structure connection fixed; chemical pipeline, equipment Fixation of pipelines, crane tracks and other construction equipment.
bolt
Bolts are mechanical parts. They are a type of fastener consisting of a head and a screw. They need to be used with a nut to fasten and connect two parts with through holes. Bolts have many names, some are called screws, fasteners, and screw nails. Bolts are tools for the gradual tightening of the machine due to the mathematical principle and physics of the circular rotation and friction of the bevel of the object.
Classification of bolts: according to the way of connection force: ordinary, with reaming holes; according to head shape classification: hexagonal head, round head, square head, countersunk head, etc.; according to thread length classification: Full thread, non-full thread; according to the tooth type classification: coarse teeth, fine teeth; according to the performance is divided into 3.6, 4.8, 5.6, 5.8, 8.8, 9.8, 10.9, 12.9 eight grades; according to the bolt making accuracy is divided into A , B, C three levels.
The difference and connection between anchor bolts and bolts
1. The anchor bolt is a kind of bolt connection form, and there are many kinds of bolt connection forms.
2. The anchor bolt is that the screw part and the concrete base material cannot be separated by some form of fixing. The detachable only nut; and the bolt, the nut is screwed off from the bolt, and the two parts can be separated. It is a detachable connection.
3. anchor bolt is a post-anchor technology, you need to drill first, then screw into the screw for anchoring; bolts are pre-formed.
4. The head of the anchor bolt is buried in the concrete base material, and the head of the bolt is exposed on the outside. The anchor bolt and the bolt are summarized: the anchor bolt is one of the connection forms of the bolt.
The above is about the introduction of anchor bolts and bolts. I believe that after you understand the knowledge of anchor bolts and bolts, you should understand the difference between anchor bolts and bolts.
