Изобретение относитс к строительству и может быть использовано дл строительства зданий в сейсмических . районах.The invention relates to construction and can be used for building buildings in seismic. areas.

Известно сейсмостойкое здание, включающее пространственно жесткие этажи с гибким нижним русом в виде высокого свайного ростверка 1.A seismic resistant building is known, including spatially rigid floors with a flexible lower light in the form of a high pile grillage 1.

Недостатком такого решени вл етс необходимость установки дополни- ,Q тельных элементов дл воспри ти горизонтальных усилий.The disadvantage of this solution is the need to install additional, Q body elements for sensing horizontal forces.

Наиболее близким по технической сущности к.предлагаемому вл етс сейсмостойкое здание, включающее прост- ,5 ранственно жесткие этажи, опертые на фундамент, выполненный в виде высокого свайного ростверка, и подвальный этаж с наружными стенами 2.The closest in technical essence to the proposed offer is an earthquake-resistant building, including simple, 5 rigidly rigid floors, supported on a foundation, made in the form of a high pile grillage, and a basement with external walls 2.

Недостатком данного здани вл ет-го с то, что наружные стены подвала закреплены между верхним и нижним рос -верками и объедин ют конструкции подвала и высокого ростверка в жесткуюThe disadvantage of this building is the fact that the external walls of the basement are fixed between the upper and the lower dews and combine the structures of the basement and the high grillage into a rigid

систему, снижающую сейсмозащитную эффективность высокого ростверка, как гибкого руса. Кроме того, необходимо устройство выключающихс св зей, что ведет к повышению расхода материалов и трудоемкости.a system that reduces the seismic protection efficiency of a high grillage, like a flexible Rus. In addition, a device for switching off connections is necessary, which leads to an increase in the consumption of materials and labor intensity.

Цель изобретени - снижение сейсмического воздействи на здание.The purpose of the invention is to reduce the seismic effect on the building.

Claims

The goal is achieved by the fact that in an earthquake-resistant building, including spatial rigid floors, supported on a foundation, made in the form of a high pile of ground grillage, and a basement floor with external walls, the basement is made with a floor slab having openings for passing the piles and rigidly connected the walls, the grillage has an overhang located with a gap relative to the outer surface of the basement walls, and the gaps between the overhang of the grillage and the walls of the basement and between the walls and the slab of the floor are filled with an elastic material. The drawing shows seismic building, section. The earthquake-resistant building contains spatially rigid floors 1 supported on a foundation of piles 2 and a grillage 3, a basement with external walls 5 rigidly connected to a floor slab 6 having openings 7 for the passage of piles 2. Roaster 3 is made with an overhang 8 located with a gap of 9 with respect to the outer surface of the walls 5 of the basement C, the gaps 9 between the overhang 8 of the grillage 3 and the gaps 10 between the 2 and the slab of the floor 6 are filled with elastic material 11, for example, rubber. Backfilling 12 and blind pane 13 is provided around the building. tea acts as a flexible floor. Piles 2 are rigidly connected with the grillage 3 and fixed in the ground. The rigid connection of the walls 5 of the basement with the slab of floor 6 forms a single box system placed freely in relation to the grillage 3 and piles m 2. Thus, there are two systems: upper rigid, connected by means of flexible pillars with the base, and the bottom box, freely placed in relation to the upper unit and the uprights, and in contact with the ground under its own weight. The seismic wave, meeting an obstacle in its path, puts pressure on the basement and causes a corresponding movement of the basement structures in the direction of the wave propagation. At the same time, during the movement of the pile foundation, the high grillage with the ground structures of the building, due to inertia, tends to maintain its previous position, shifting relative to the base towards the movement of the basement. These movements are limited to 3a3opq.B, as well. The force interaction between the structures of the basement and the high grillage is softened by an elastic material placed in the gaps. The building structure allows to increase the seismic resistance of the building, by using the basement design as a quenching element, and reduce material consumption by eliminating the need to install additional off-connections. Claims of the invention A seismic resistant building comprising spatially rigid floors supported on a foundation made in the form of a high pile grillage and a basement with exterior walls, in order to reduce the seismic effect on the building, the basement is made with a floor slab having openings to pass the piles and rigidly connected to the walls, the grillage has an overhang located with a gap relative to the outer surface of the basement walls, The floor is filled with elastic material.
