Expansion anchor is a common construction material used to fix and connect concrete, brick walls and other building structures. Its main feature is that it can produce expansion force in materials such as concrete or brick walls, which will fasten the anchor bolts in fixed position and thus achieve a strong effect.
The expansion anchor consists of two parts, one is the anchor itself, usually made of steel, stainless steel, aluminum alloy and other materials; the other is the expansion body, usually made of plastic or rubber and other materials. The function of the expansion body is to keep the anchor bolt tight when it enters the hole, and when the anchor bolt rotates, the expansion body will be compressed, thus producing expansion force to fix the anchor bolt in the hole.
The advantages of expansion anchor are its easy and fast installation, firm fastening and long service life. It is usually used to fix various building structures, such as steel structures, pipes, air conditioning brackets, wire and cable bridges and so on. In the process of use, it is necessary to choose different types and specifications of expansion anchor according to the actual situation to ensure its fixing effect and safety.
However, there are some limitations of expansion anchor bolts, such as easy to produce hole cracking when the material or structural strength is low, and easy to produce rusting in wet environment. Therefore, when selecting and using expansion anchor bolts, it is necessary to consider various factors according to the actual situation, select the most suitable anchor bolt type and specification, and strictly follow the instructions for installation and use.
In a word, expansion anchor is a common construction material with the advantages of easy and quick installation, firm fastening and long service life, which is one of the important materials for fixing and connecting building structures. In the process of use, attention should be paid to the selection of appropriate types and specifications, and installation and use in accordance with the instructions to ensure its fixing effect and safety.
