Differences between bolts
Ordinary bolt is one of the commonly used fasteners in steel Structural engineering. The welding nail manufacturer's welding nail belongs to a type of high-strength and rigid connection fastener. The welding nail is the abbreviation of Cheese head studies for arc stud welding, and the specification of the welding nail is the nominal diameter Ф 10~ Ф 25mm, with a total length of 40-300 mm before welding. Welding nails have the identification mark of the manufacturer made of raised characters on the top surface of the head, and the use of welding nails is very extensive. Steel structure bolt manufacturer Steel structure bolt is a high-strength bolt and also a standard component. The fastening performance is relatively good, used in steel structures and engineering, to enhance the fastening effect. On general steel structures, the required steel structural bolts are grade 8.8 or above, as well as grade 10.9 and 12.9, all of which are high-strength steel structural bolts. Sometimes, the bolts on steel structures do not need to be electroplated, and it is OK to use the natural color. It is more suitable for connecting various parts in the middle of steel structures, playing a more solid role. It can also be said that some parts are dispersed and become a complete individual through bolt connections. Common bolts commonly used in daily life include hexagonal bolts, stud bolts, and anchor bolts fixed to the ground. Next, let's ask the person in charge of the new national standard bolt manufacturer to explain their scope of use
1. Hexagonal bolts are usually more suitable for steel structures to play a temporary and secure role during installation, or to simply accept some blocking forces caused by friction between steel plates and do not act on other important connections. However, on the surface of some more important connections, if thick bolts are used for connection, it should be ensured to add suitable supports that can withstand shear forces during this period.
2, commonly referred to as double headed bolts. At the convergence of the slab, some areas do not fit with the hexagonal bolts
III. Foundation bolts can be divided into several types according to their functions. Each type is responsible for different fields, which can effectively fulfill their responsibilities. It can be said that as long as it is a construction project, they are visible and provide an undeniable contribution during the construction process.
