Rigel is a word with many meanings. There are about ten of them. They are called building elements, part of the lock, a jewelry tool, and this is also a common German surname. In jewelry, bolt is used to align, reduce, or increase the size of rings or bracelets. The material is steel, often on the instrument there is a size scale. It is also used for the manufacture of chains and other complex products. Jewelry bolt has a different shape in cross section: square, rectangular, round, and so on.
But most often the word "bolt" is found in less specific areas. The closest concept to every person is the lock bolt.
Rigel as part of the castle
When the door closes, the key is turned and a locking pin appears. Durable locking part - this is the bolt lock. In Russia, when it became necessary to lock the doors, the first overseas locks with a sliding part appeared. Not everyone could get a complicated novelty, but bolts of varying complexity were used, they were also called bolts. That is, a bolt is a metal pin or several pins tightly covering the door.
Modern door locks can hold from two to six round bolts; the more, the better and more reliable the locking reliability of the lock. The reliability of the bolt locks depends on the metal from which it is made. The best material is steel. It is important here that the mate in the door frame and the box itself are also made of high-strength materials and securely mounted. The simplest bolt is a single, rectangular shape. This type of castle has almost become obsolete in our realities and will soon become a rarity.
Rigel in construction
In construction, a bolt is a support, a support beam. To understand where it is located, it is necessary to present a small one-story house. Installation of a gable roof of a house can not do without a horizontal support beam, or bolt. All supporting roof structures are mounted on it. The material for the construction bolt are metal, wood, reinforced concrete. What material is better to use the support when building a house depends on the building itself. For a typical apartment building use reinforced concrete support, and in wooden houses the use of a bolt from natural material is organic.
Quite often confused the concept of bolts and beams. The main differences are in several points:
- The bolt function is a horizontal support.
- The function of the beam - building overlap.
- A crossbar is a rigid fixed frame support.
- A beam is a flexible element of structures.
- The material for the bolt: reinforced concrete, metal, wood.
- Material for beams: wood, metal.
Reigel reinforced concrete used in bridge building. The horizontal concrete element firmly connects and interconnects the vertical supports of the bridge. That is, the bridge bolt is laid from one bridge support to another, which allows the structure to be strong and gives it initial stiffness.
According to the field of destination, the bolt from reinforced concrete is divided into several types. Parameters, sections, requirements for the composition of concrete are governed by GOST number 13015.0. Thus, the standard specifies for what indicators and in what conditions of operation certain bearing parts should be used.
In modern construction columns are used for the construction of residential, non-residential and industrial buildings. This method of construction allows you to get the maximum amount of free space and does not depend on the height of the building. This is the so-called frame building. Columns are made of reinforced concrete, structurally they are two-console, single-console and console-free. The connection of the bolt and the beam occurs through the console. The connection takes place with the help of the design features of the bolt and the column, as well as the metal mortgages enclosed in the reinforced concrete elements of the joints being joined. Mounted connection "bolt-column" by laying the ends of the bolt on the connecting pins of the column. To strengthen the connection it is additionally concreted, ensuring solidity of the structure.
The cross-column connection allows to erect buildings of any height and large area. However, this construction has its drawbacks: it is rarely possible to achieve a perfectly flat horizontal position at the junction of several columns by means of transverse bolts, which causes distortions and the reliability of the building is jeopardized.
