The word "Rigel" is German and translated into our language means a crossbar or transverse beam. The name defines the location and meaning of this detail.
These structures are load-bearing structures in the frame of the building, usually located horizontally.
Two vertical supports are well connected to each other, and such a connecting element distributes the weight of the slabs or floors to the columns , which are installed under the edges of the transom.
And also a crossbar is called a set of parts used in different areas.
For example, this is what they call:
Crossbar in jewelry used to align or reduce the size of bracelets and rings. The tool is made of steel and has a measuring scale.
This tool is also used for the production of chains and other products.
Jewelry ledger of various cross-sectional shapes, for example, square, rectangular, round.
The bolt is also used in less specific areas, for example, in door locks.
When you close the door with the key, they make a turn and a closing pin appears. This pin is the bolt of the lock.
In ancient times, when the need arose to close doors with locks, the first foreign locks with a part that slide out appeared. And since not everyone could acquire such complex locks, they began to use various bolts of varying complexity and they were also called crossbars.
In fact, a deadbolt is a pin or several pins that close the door.
Modern locks have up to six round-shaped crossbars.
The bolt lock is reliable only if it is made of good metal.
Steel is considered to be the best material for making a crossbar.
A very important nuance is that the mating part of the door frame and the frame itself should also be made of very durable materials and well-installed.
The single rectangular transom is the simplest. This type of castle is almost never used, and soon it will become a rarity.
In construction, a crossbar is called a support, that is, the support beam.
In order to understand where the crossbar is located, it is necessary to imagine a small house with one floor.
The erection of a gable roof of a house cannot be done without a support beam, which is located horizontally or in another crossbar.
All important roof structures are attached to the crossbar. For a construction crossbar, materials such as wood, metal, reinforced concrete are used.From what kind of building will be chosen and the material for the crossbar.
Reinforced concrete girder structure is used for apartment buildings, for wooden houses a girder made of identical material is used.
The concept of a crossbar and a beam is often confused.
But there are still differences, and they have several points:
Reinforced concrete the crossbar is used in bridge construction. Such a horizontal, reinforced concrete structure connects well and connects the vertical supports of the bridge to each other. Due to the fact that the crossbar is laid from one bridge support to another, this allows the entire massive structure to have rigidity and strength.
Reinforced concrete girders, according to the area of destination, are divided into several types.
All characteristics, sections, requirements for the composition of concrete are stipulated by GOST, the number of which is 13015. 0. This standard prescribes by what indicators and in what conditions the supporting parts should be used.
In construction, columns are used for construction residential, industrial and non-residential buildings.
This type of construction allows you to get the largest amount of area and it does not depend on the number of storeys of the building.
This is called frame construction.
Such columns are produced from such material as double-cantilever, single-cantilever or non-cantilevered. The beams and the transom are connected through the console. This connection takes place using the design features of the girder and the column, as well as metal mortgages. Installation of the "crossbar - column" connection is carried out by laying the ends of the crossbar on the connecting pins of the column.
To make the connection strong, it is additionally poured with concrete so that the structure is monolithic. Thanks to the girder and column connection, it is possible to erect buildings of any height and large area.
But with this construction option, there are some drawbacks, for example, it is almost impossible to achieve a very even horizontal position at the junction of several columns due to the transverse girders, therefore distortions occur. Because of these distortions, the building's reliability is low.
Well, in this article we talked about such a detail as "Rigel", we hope that this information will be useful to you.
Good luck and patience!
