To date, it is generally accepted that the bolt is a part of the lock, with the help of which the door is locked and further kept closed. However, this opinion is only partially true, since it will be more correct to claim that this element is a metal cylinder that extends from the lock shell in the direction where the door frame is located . Since this comparison is just a particular example, we turn to the "Architectural Dictionary", which will help give a competent definition of the term in question.
So, each civil engineer knows that the crossbar is a linear bearing component, which is a rod (beam). The crossbar itself is located horizontally and is used in the construction of various structures, structures and buildings. It can hinged or rigidly connect various vertical structural parts, columns, columns. This element is also support for slabs installed in the floors of buildings. Nowadays reinforced concrete crossbars are actively used in the construction of bridges. Actually, no bridge can do without it.
In addition to reinforced concrete, there are wooden and metal crossbars. They are used, as already mentioned, to give stability to the foundations of power lines, increase the strength of the foundations of buildings and structures, as well as to strengthen any structure that is under horizontal load.
Thus, the crossbar is an element of the building structure, the task of which is to provide maximum load-bearing capacity even under huge loads. So this part is indispensable in construction and is found almost everywhere.
For example, consider a rack-mount and crossbar design. In most cases, they are used to build a profile facade, the main elements here are supporting vertical posts and horizontal reinforced concrete crossbars attached to them. Thus, the supporting structure in such a structure is located on the inside of the wall.
It should be noted that the connection of crossbars and racks can be performed in different ways. For example, overlapping (profiles half overlap each other). So, the crossbar is attached to the rack by means of an aluminum connector installed in it using clamping screws. Then this connector is attached to the supporting vertical profile with screws, and the connection is sealed. These measures ensure the stability of the entire structure.
Horizontal and vertical profiles can be connected by deepening the bolt into the grooves made in the vertical profile. Special plastic parts are glued to their joints, which are used to remove moisture outward, which allows the joint to be sealed.
Thus, the crossbar is an essential part of any design, which allows you to connect supports, racks, rafters and more. Probably not a single building can do without this element, because the stability and strength of the entire building or structure depends on it.
