A technique for protection of surrounding external walls from earthquakes

Abstract

The title of the invention is "Protection of surrounding external walls from earthquakes", that argues for the purpose of this invention, consisting of a construction method that enables the resistance and solidity of surrounding external walls from shocks during earthquakes

Description

[0001] The invention focuses on a building practice in the construction sector, where one of the main elements is the surrounding external walls of an object. The quality and technique followed for their construction plays a key role against the risk factors such as seismic shocks from earthquakes. Therefore, with this invention, a special building technique is claimed, which is applied after the project design phase is finished and the construction phase kicks off.

[0002] Upon reaching the "0" quota (ground level), the construction progresses with erection of concrete columns, reinforcement frameworks and building of the floors, where normally the height of the floor is 2.8 m-3.6 m.

[0003] For each concrete column, two long "L"-shaped profiles with a height of 2.8 m-3.6 m, width 5 cm (depth) and thickness of 3 mm, are applied. To each "L" -shaped profile, on one side, three Φ16 rods of 20 cm are welded, which are inserted into the column during the concrete casting process.

[0004] Depending on the thickness of the bricks determined in the project design phase, for example 20 x 25 cm, the reinforcement frame is prepared for the columns, placing the "L" -shaped profiles in such a way as to maintain the distance and the space taken by the brick; The brick will be inserted 5 cm into the width of the "L"-shaped profile. In a similar way, preparations are made to all concrete columns, on each floor, to the entire perimeter of the building.

[0005] After finishing the carcass together with the setting of the profiles, the building works for the surrounding external walls begin, inserting the bricks 5 cm to the depth of the "L"-shaped profile. At every 1-meter height of the wall, a concrete reinforcement band is established with inserting 3 or 4 iron bars of Φ 10. This makes it possible and ensures 100% (the outmost) solidity and stability of the surrounding external walls from the earthquake's impacts

[0006] Likewise, even if the carcass is finished and "L" -profiles are not installed, steel strips can be ordered, according to the project design and thickness of the concrete columns, and which can be equipped with nuts and bolts to enable fixing and fastening of the "L"-shaped profiles to the bottom and top of concrete columns, even though such profiles are not placed / inserted in the concrete column the concrete casting process.

[0007] Or, even when the object is finished, as well as the carcass and masonry are completed, but the "L"-shaped profiles have not been inserted, it is possible to fix the "L"-shaped profiles by grinding the bricks that are adjacent to the concrete column on both sides 3 cm; then the "L"-shaped profiles are placed as defined above inserted into the brick and fastened up and down with the steel strip, tightening them tightly, managing to do the same action as if the "L"-shaped profiles were inserted into the wall.Applicability to industry

[0008] By means of this invention, it is intended to represent a building technique that enables the solidity and stability of the surrounding external walls in various objects, during risky situations, especially during seismic shocks from earthquakes.
