Different types of steel are used in various engineering and building constructions, as well as different technical parameters and specifications. Steel can generally be divided into four main categories of models, plates, pipes and metal products, and may be used in many different types of steel in general engineering, but do you understand the various types of steel? Here's what the rabbits will tell you。
It is named after the cross-section shape of the steel, which, in general, is a bar-shaped piece of steel with the cross-section word “work” or the word “h”, and which is referred to as the sorghum for construction, i. E. The main purpose used to carry weight. It is widely used in a variety of structures, bridges, vehicles, stubbles, machines, etc., such as the construction of bird nests in beijing, where it can be used in large quantities, as well as in various construction frames where it can be seen。
The difference in specifications can be broken down into three main categories of general, light and h type steel, depending on the specifications, which can be found mainly in the three dimensions of waist height, leg width and waist thickness, i. E., the specifications of a general type steel are typically expressed in the size of the waist * leg width * waist thickness (generally mm), although some of the specifications are expressed directly in the waist height, e. G. The height of the 11# piece of steel is 11mm。
The difference between normal, light and h type steels is mainly in cross-section shapes, which should be further defined as the difference in wing shapes, where the wings of the former are thick insides, while the wings of h lines are as thick as inside and outside. As the specifications of the three types of steel vary, so do their performances, their specific uses vary in construction. We should not make random choices when choosing to use a work-word steel, but should strictly follow the requirements of the design drawings to select suitable types and specifications。
In addition to its type and corresponding specifications, the theoretical weight of the steel will be taken into account in the construction of the works. So how do we calculate the theoretical weight of the different types and specifications of steel? It's really simple to say that the theoretical weight of the steel is = the volume * density per metre, and the professional calculation is = 0. 00785 x waist per metre. Thick
High +f (legs wide - waist thick)
, of which f is searchable. Here's a list of the theoretical weights of the construction steel:
Through the formulas and reference tables described above, it is clear to us that the theoretical weight of a work-word steel is determined by factors in both its size and its specification, and that, when used, we can carry out actual weightings based on the reference form to test the suitability of the work-word steel。
