Anchor bolt installation has always been the focus of attention in the industry. In simple terms, it is a mechanical component. It is mainly installed in concrete that meets the standards. The shape of the bolt is rather special, presenting a J-shape, and one end of the mechanical component is buried in the concrete during the operation. Its main role is to fix related objects. As the types of anchor bolts on the market have started to increase, different types of anchor bolts have different mounting methods. The following is a summary of the basic procedures for the installation of the anchor bolts . There is a need for friends to go along with a simple understanding.
Anchor bolt material
1. Although the general anchor bolts are made of Q235 steel, they are not the most rigid, but they are more convenient for making the shape and details of the anchor bolts. Q235 steel is a kind of carbon structural steel, which can be directly used without heat treatment under normal circumstances. Is a very convenient steel.
2. Q345 rebar. It is a low-grade steel, and the hardness of this steel is greater. And has good mechanical properties, low temperature, plasticity and weldability are relatively good. Can be widely used in various industries.
3. Low-alloy high-strength structural steel (16Mn) has less carbon and gold content. The main materials are: manganese materials, silicon materials, vanadium materials and so on. Because of its low content of alloys, the weldability is better than that of ordinary alloy materials, so no preheating is required in welding applications.
4.40Cr steel. Compared with the above several types of steel, the strength of the anchor bolts made with it is the highest. And it has very good comprehensive mechanical properties after some special treatment. It also has good toughness under low temperature conditions and also has good sensitivity to notch.
Anchor bolts classification
Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, anchor anchor anchor bolts and bonded anchor bolts. According to the different shapes, they are divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded pre-embedded bolts, and embedded bolts on the floor.
Anchor bolt effect
1. The fixed anchor bolts are grounded with cement and other items to fix the equipment without strong vibration and impact.
2. The movable foot is a kind of detachable anchor bolt that can fix large-scale machine equipment with strong vibration and impact.
3. Expansion anchor anchor bolts are used to fix relatively simple and lightweight equipment and auxiliary equipment under standstill.
4. Bonding The anchor bolt is a widely used and common device, and it is also a small piece for fixing a simple device.
Anchor bolt calculation
Calculation of the tensile strength of the anchor bolt: The tensile strength of the bolt is the tensile strength of the round bar itself, and the size is equal to the cross-sectional area multiplied by the tensile strength design value of 140 MPa. The resulting value is the design of the anchor bolt. Allows for tensile load capacity.
Anchor bolt installation
First, first of all, professional technical personnel should follow the relevant design requirements, so as to meet the requirements of standards for the number, type, category, and material of the anchor bolts.
Second, after purchasing the required anchor bolts, we should let the engineering technicians perform the relevant standard measurements. Then based on the measured data, design the position, height, etc. of the anchor bolts that need to be embedded.
Third, the staff should first install a fixed bracket before the anchor bolts are installed. Only the bottom of the bracket must be welded firmly to form a system that meets the standards. In addition, it must be ensured that the fixed bracket has strong stability and sufficient rigidity.
Fourth, after the related bracket is fixed, the anchor bolt installation procedure can be started. When the anchor bolt is installed, the center position of the anchor bolt must be fixed according to the relevant positioning line. Then start adjusting where it does not meet the requirements. And take the correct method to reinforce it firmly.
Fifth, after installation of the anchor bolts, the staff should use professional measuring equipment to adjust the anchor bolt several times. Ensure that the level of the anchor bolts as well as the elevation can meet the requirements.
Sixth, after confirming that all the anchor bolts have been installed, after detailed inspection to ensure compliance with relevant requirements, the bottom of the anchor bolts shall be welded securely. Bolt brackets are usually reinforced.
Editing summary: It should be understood that the installation procedure of the anchor bolts can be said to be very different. Because there are all kinds of anchor bolts on the market, everyone must pay attention to the specifications of the program when installing. In addition, more attention needs to be paid to the safety of operators and the correct use of equipment. There are many small things like this in life, although they look small and inconsequential. It has a great effect and brings more convenience to our lives.Bolts and nuts hexagon head bolt bolt fastener construction installation belt loft how to fit the anchor bolt installation
