Archi doorways are designed for the visual zonality of the premises, their use allows you to visually divide the living space into separate rooms without installation of doors. To date, the choice of arched openings is huge, which indicates a high demand for this construction and decorative material.
Arkal openings can have both a firing and a rounded circuit, in turn, arches with a rounded outline are divided into four main types:
Classic – an arc with a uniform, correct radius;
Modern – an arc with a rise;
Romance – arc with rounded corners and a direct central part;
Ellipsoid – an arc in the form of a uniform or curved ellipse;
Today, there are many ready -made arched openings with a variety of style in the construction markets, as a rule, their set includes four racks, two arches, panels and narrow or wide decorative locks, as well as various decorative elements can be attached to a set of goods. The vast majority of standard modular arches are made from the Ministry of Internal Affairs, and are intended for the openings for openings up to 233 cm high, from 82 cm wide to 155 cm with wall thickness from 5 cm to18.5 cm.

For the production of arched openings, various materials are used, however, it is on the type of material used for the manufacture of arches that their main spectrum of use depends. Consequently, products made of more durable materials, such as concrete, wood, brick, can be used both inside and outside the room, and arches from less reliable materials in particular products from plastic, gypsum, chipboard and fiberboard are intended only for the inside of the dwelling.
Brick arches are a kind of arched masonry, which looks most effective in the width of the opening of 2 m or more. Initially, for the formation of a brick arch along its contour, it was made circled, it makes up the formwork on which bricks are laid, and after the solution hardens, the formwork is eliminated from the doorway. For the formation of brick arches, pattern bricks are most often used, since one end of it is wider than the other, which allows you to create the same seams between bricks. When using conventional brick, the seams of the binder solution will have a cone -shaped look, while their width should not exceed 25 mm in the upper part and be less than 5 mm in the lower.
Wooden arches – products from wood, can be made both of the whole wooden canvas and consist of several elements that are called planned glued arches. Products from the whole wood and its elements are characterized by low strength, since the material with significant loads is easily deformed, that is, it is drying out, cracking and breaking along the fibers, to strengthen the material, boiling or evaporation technology, as well as the use of transverse wooden bars and condenses are used. The basis of the modern production of wooden arches is glued material (chipboard, fiberboard, etc. D.), which allows you to create products of any length and shape, preserving the excellent operational qualities of finished arched openings.
