Description

(54) УСТРОЙСТВО ДЛЯ ГАШЕНИЯ КОЛЕБАНИЙ(54) DEVICE FOR EXTINGUISHING VIBRATIONS

1one

Изобретение относитс  к строительству и предназначено дл  гашени  механических колебаний зданий и сооружений.The invention relates to construction and is intended for damping mechanical vibrations of buildings and structures.

По основному авт. св. № 726280 известно устройство дл  гашени  механических колебаний зданий и сооружений, включаюш .ее массу, шарнирно подвешенную на стержн х по периметру здани , имеюшего фундамент , снабженное валом, концы которого жестко заделаны в фундамент-здани , а масса выполнена в виде двуплечего рычага, жестко закрепленного на валу, а стержни предварительно напр женыС,According to the main author. St. No. 726280 a device is known for damping mechanical vibrations of buildings and structures, including its mass hinged on rods around the perimeter of a building that has a foundation equipped with a shaft, the ends of which are rigidly embedded in the foundation-building, and the mass is rigid mounted on the shaft, and the rods are prestressed,

Недостатком этого устройства  вл етс  то, что в сечени х вала жестко заделанного в фундамент, возникают большие изгибаюшие моменты, а дл  обеспечени  прочности вала увеличивают плошадь его поперечного сечени , что вызывает дополнительный расход металла. Кроме того, наличие изгиба вала уменьшает надежность работы устройства и ухудшает его диссипативные характеристики .A disadvantage of this device is that in the cross sections of the shaft rigidly embedded in the foundation, large bending moments occur, and to ensure the strength of the shaft, the area of its cross section increases, which causes additional metal consumption. In addition, the presence of the bend of the shaft reduces the reliability of the device and affects its dissipative characteristics.

Цель изобретени  - повышение надежности работы за счет устранени  изгиба вала и улучшение диссипативных свойств.The purpose of the invention is to increase reliability by eliminating shaft bending and improving dissipative properties.

Указанна  цель достигаетс  тем, что устройство дл  гашени  колебаний снабжено анкерным стержнем в виде петли, огибаюшим вал, концы которого закреплены в фундаменте.This goal is achieved by the fact that the device for damping vibrations is provided with an anchor rod in the form of a loop, which bends around a shaft, the ends of which are fixed in the foundation.

На фиг. 1 изображено предлагаемое устройство, обший вид (сечение Б-Б на фиг. 2); на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the proposed device, a general view (section BB in Fig. 2); in fig. 2 is a section A-A in FIG. one.

Устройство включает массу 1, шарнирно подвешенную на стержн х 2 и жестко закреп10 ленную на валу 3, концы которого с помошью анкеров 4 заделаны в фундамент 5. Стержни 2 пропушены через кладку стен 6 и верхними концами закреплены на железобетонном сейсмопо се 7 нат жными гайками 8 через опорные пластины 9. В середи15 не пролета вала 3 закреплены анкерным стержнем 10 в виде петли, огибающей вал, концы анкерного стержн  закреплены в фундамент 5.The device includes a mass 1, hinged on rods x 2 and rigidly fixed on shaft 3, the ends of which are embedded in foundation 5 using anchors 4. through the supporting plates 9. In the middle of the 15th span of the shaft 3 are fixed with an anchor rod 10 in the form of a loop enveloping the shaft, the ends of the anchor rod are fixed in the foundation 5.
