Expansion bolt specification table
Expansion bolt is a commonly used connecting piece. It has the characteristics of high strength and corrosion resistance, and is suitable for connecting various building structures. The expansion bolt specification table is the parameter index of expansion bolt products, which includes bolt diameter, length, tensile strength, embedded depth and other information, providing an important reference for users to select and use expansion bolts.
When rewriting the expansion bolt specification table, we can sort it according to different indicators and continue writing based on actual application scenarios to meet user needs.
1. Sort by bolt diameter
Bolt diameter is a key parameter in the expansion bolt specification table, which directly determines the load-bearing capacity of the bolt. Therefore, it is common to sort bolt diameters in specification tables.
1. M12 expansion bolt
The diameter of the bolt is 12mm, which is suitable for the connection of light building structures, such as steel-wood structures, thin-board houses, etc.
2. M16 expansion bolt
The bolt diameter is 16mm, which is suitable for the connection of medium-sized building structures, such as steel structures, frame structures, etc.
3. M20 expansion bolt
The diameter of the bolt is 20mm, which is suitable for the connection of large building structures, such as high-rise buildings, bridges, etc.
4. M24 expansion bolt
The bolt diameter is 24mm, which is suitable for the connection of very large building structures, such as large factories, viaducts, etc.
2. Sort according to tensile strength
In addition to bolt diameter, tensile strength is also an important parameter in the expansion bolt specification table, which characterizes the mechanical properties of the expansion bolt. Sorting by tensile strength in the specification table can help users select suitable expansion bolts.
1. Grade 4.8 expansion bolts
The tensile strength is 400MPa, suitable for light-load connections in light-load structures.
2. Grade 8.8 expansion bolts
The tensile strength is 800MPa, which is suitable for normal load connections in general building structures.
3. Grade 10.9 expansion bolts
The tensile strength is 1000MPa, which is suitable for connections that exceed normal loads in large building structures and heavy-loaded structures.
4. Grade 12.9 expansion bolts
The tensile strength is 1200MPa, which is suitable for connections with high performance requirements for expansion bolts in special projects.
3. Sort by length
The length of the expansion bolt is also an important parameter in the expansion bolt specification table. It is related to the embedded depth and directly affects the load-bearing capacity of the expansion bolt. Sorting by length in the specification table makes it easier for users to select suitable expansion bolts.
1. Short expansion bolt
The length of bolts is generally 50mm-100mm, which is suitable for connections with shallow burial depth and light load.
2. Medium-length expansion bolts
The length of bolts is generally 100mm-150mm, which is suitable for general building structures and general load connections.
3. Long expansion bolt
The length of bolts is generally 150mm-200mm, which is suitable for connections in large building structures and heavy-loaded structures.
4. Sort according to embedded depth
In addition to the length, the embedded depth is also an important parameter in the expansion bolt specification table. The embedded depth determines the stress state of the expansion bolt. Sorting according to embedded depth in the specification table allows users to select suitable expansion bolts more accurately.
1. Small embedded depth expansion bolts
The embedded depth is generally 4-5 times the bolt diameter, which is suitable for shallow buried depth and light-load connections.
2. Medium embedded depth expansion bolts
The embedded depth is generally 5-7 times the bolt diameter, which is suitable for general building structures and general load connections.
3. Expansion bolts with large embedded depth
The embedded depth is generally 7-10 times the bolt diameter, which is suitable for connections in large building structures and heavy-loaded structures.
To sum up, the expansion bolt specification table includes parameters such as bolt diameter, length, tensile strength, embedded depth, etc. By sorting according to different parameters and continuing based on actual application scenarios, it can better help users choose suitable bolts. Expansion bolts ensure the connection quality and safety of the building structure.
