Service Hotline1. Fixed anchor bolts, also known as short anchor bolts, are poured together with the foundation and used to fix equipment without strong vibration and impact. 2. The movable anchor bolt, also known as the long anchor bolt, is a detachable anchor bolt used for fixing heavy machinery and equipment with strong vibration and impact. 3. Expansion anchor bolts are often used to fix stationary simple equipment or auxiliary equipment. The installation of expansion anchor bolts should meet the following requirements: the distance from the center of the bolt to the edge of the foundation shall not be less than 7 times the diameter of the expansion anchor bolt; the foundation strength of the expansion anchor bolt shall not be less than 10MPa; there shall be no cracks in the drilling holes. The drill bit collides with the steel bars and buried pipes in the foundation; the diameter and depth of the drill hole should match the expansion anchor bolts. 4. The bonding anchor bolt is a kind of anchor bolt commonly used in recent years, and its method and requirements are the same as the expansion anchor anchor bolt. However, when bonding, pay attention to blowing out the debris in the hole, and do not get wet. [1]
The use of Portlandstainless steel screw lines: The hardness of Portlandstainless steel screw lines causes them to have different uses. Generally, they are used as small screws in life, but also as car screws and compression screws. They are widely used in normal life. Types of Portlandstainless steel screw lines: In appearance, screw lines are generally divided into fog surface spring lines and bright surface screw lines. The hardness of matte surface screw lines is higher than that of bright surface screw lines. For products with low appearance requirements and relatively high elasticity requirements. Paper, oxalic acid, fertilizer and other production equipment; photography, food industry, facilities in coastal areas, ropes, CD rods, bolts, nuts.
PortlandSelf-tapping screw is a kind of threaded fastener that self-tapping and drilling the matching female thread in the pre-drilled hole of metal or non-metal material. When using self-tapping screw, a flat washer is often required to protect the fastening surface. Traditional When the self-tapping screw is used, the flat pad is easy to fall off, resulting in low work efficiency. In view of this, we propose a combined structure of the stuck self-tapping screw PortlandPortlandspring washer that prevents the flat pad from falling off.
Riveting is a method for combining two pieces of metal. Therefore, riveting technology is often used to fasten rivets such as nuts or rivets to metal sheets.
How to use, what is a PortlandPortlandrivet nut? Usually, PortlandPortlandrivet nuts used inside elevators are used to install some kind of screws when installing various parts on cars or individual boards on aviation. Commonly used places are very important connection parts, so the choice of PortlandPortlandrivet nut material is very important. How to use the PortlandPortlandrivet nut? Let's watch it together. Rivet nuts are used in the fixing fields of various metal plates, pipes and other manufacturing industries, and are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. It is designed to solve the shortcomings of sheet metal, thin-walled pipe welding nut, substrate welding deformation, internal thread taper, etc. It does not require internal thread, welding nut, rivet efficiency, and is easy to use.
