Stone in building
Ancient Stone Age and Paleolithic periods represent periods in which the use of stone is preceded by metal and other materials. The works of houses made of stone, located 7000 in the north of Iran are available. The general properties of rocks are generally classified from the origin to igneous, sedimentary and metamorphic rocks. In the study of the general properties of stones, such as tensile strength, pressure tolerance, permeability, propagation of waves, stability, and considering the layering and poor levels of operations, it should be noted that rocks typically have surfaces in which force Adhesion and bonding of seeds are less or less than other layers.
In general, the strength of a building stone without a groove, streaks, cracks, pores, decay and loose layers,
and even a uniform color should be considered.
In general, natural stone with sufficient resistance to atmospheric conditions and interesting colors can be used in construction operations and in the form of carcasses, rock, flint, stone plaque, capstone, stone pillar and even in the form of utensils and stoneware. Made The rocks and all sorts of large stone-like stone-making rocks are known as the "Stone of Peak". Peak rock should not be crushed under the cutting blade, and even large and portable, the rock will be separated from the mine by a fork, blast or cut, and ready to work, depending on the type of genus and its application in the workshop. . Using rough and friable rocks using roots and hammers, they will first cut the decorative stones and wash them during the cutting, to wash the stone and grab it.
Then, depending on the importance and quality, it will be polished and polished.
The rocks used in the building are called stone carvings, rocky slabs, stones, and plain bearing plaques, which are
described as follows:
Carcasses: A rock that does not have a particular shape and is used in the same way as the mine is used, and its use in substructures is limited by filling the gap between rocks and flooring. Swamp Swamp (Malone): It is a rock that is arranged in a perfectly shaped manner, and in particular one side of it, forms a smooth shape. Fountains are used in tunneling, bridging, table-laying, winding and non-fading walls, pavers, and stairs, and one of the most important uses of carcass and Malone stone engineering, especially in mountainous areas, is the execution of rock arches on bridges, ports and The arches below the stone corridors are used.
Swamp Rock: It is a stone made from carcass stone, and it has a regular dimension in a construction worker with a slightly angular structure and has certain corners. It is used for slab walls, slabs and flooring that require a bit of facade. Plaque (decor): For the facade, the plaque is used on the surfaces. To make plaque stone, cut rock at a stone workshop to the desired thickness, and then cut it to polished and mirrored. The plaque is used to decorate the interior and exterior of the building and in the facade, floor, wall of the staircase, the floor of the window, beside and under the wall of gypsum and decorative items such as vases, candlesticks, tables, and so on. koohistone.net tags: teravertine barble bosh hammer limestone
