For construction, it is important that there is mutual understanding between different people. And for this it is necessary to use the same terminological base. In the framework of this article we will try to clarify this issue.
What is the butt?
This word is ambiguous. In the general case, the end face is the transverse face of an object that has an extended shape. To imagine what is at stake, think of a rectangular parallelepiped or a cylinder. If we consider the first figure, then in it the end face is the smallest face in terms of area. If a material that has a directed structure is used as a parallelepiped, then the end face is a plane that is perpendicular to the direction of the material structure. As a practical example, wood is suitable in which the fibers are elongated in the direction of growth. The situation is different in cylinders. In them, the end face is the part that is in the plane that is perpendicular to the longitudinal axis. It has the shape of a circle. This word can also be used in the meaning of "log end" when it is necessary to indicate to another person the features of construction work.
Butt in buildings
A separate understanding exists regarding buildings. So, when they talk about buildings, in this case the end face is the narrow side of the structure, which is not a facade. When there is a gable roof, it can also be called a pediment. Where the front side and the end face coincide, this term is undesirable to use. As an example, the names of such buildings are suitable: the Acropolis, the Bolshoi Theater, the arena. We hope that it is now clear why such a rule exists in the construction field.
Bridge
There is also another context of use. In it, the end face is a wooden tile that is used to create pavements. They mean hard road surface. It can be made in the form of laying wooden boards to create convenient conditions for the movement of pedestrians (which is quite popular) or to overcome transport problem areas where permanent laying such as asphalt or gravel has not been carried out. About the use of this material in a similar way there are recollections of chronicles from the times of Kievan Rus.
Conclusion
As you can see, the butt is a rather popular and multifaceted word. It can be used not only in the field of construction, but also in other areas of human activity.
