(5+) ФУНДАМЕНТ ПОД КОЛОННУ(5+) FOUNDATION UNDER COLUMN

II

Изобретение относитс к строительству к касаетс возведени фундаментов под колонны промышленных зданий, опоры высотных сооружений.The invention relates to the construction as concerns the construction of foundations for columns of industrial buildings, supports for high-rise structures.

Известен фундамент под колонну, состо щий из плоской опорной плиты со стаканом и примыкающей к ней оболочки со сквозным стаканом 1.The foundation for the column is known, consisting of a flat base plate with a glass and an adjacent shell with a through glass 1.

Однако в таком фундаменте его несуща способность при больших эксцентрично приложенных нагрузках вл етс недостаточной.However, in such a foundation, its carrying capacity at large eccentrically applied loads is insufficient.

Наиболее близким к предлагаемому вл етс фундамент, представл ющий собой оболочку, собираемую из отдельных вертикальных секций, распираемых в грунт подкосами подколонника , имеющего наклонные боковые грани t2.The closest to the present invention is the foundation, which is a shell, assembled from separate vertical sections, which are pushed into the ground by subkolnik struts having inclined lateral faces t2.

Недостатком этого фундамента вл етс больша трудоемкость его возведени .The disadvantage of this foundation is the great complexity of its construction.

Цель изобретени - снижение трудоемкости: возведени фундамента. iThe purpose of the invention is to reduce the complexity of the construction of the foundation. i

Указанна цель достигаетс тем, что фундамент под колонну, включающий размещенную в грунте составную из вертикальных секций оболочку, в которой размещен подколонник, имеющий наклонные боковые грани, снабжен опорной плитой, на которой установлены секции оболочки; причем кажда секци выполнена в виде объемного блока, одна бокова грань которого выполнена наклонной в сторону вертикальной оси фундамента и обращена к подколоннику , две выполнены вертикальными и обращены к грунту основани и две остальные выполнены вертикальными и обращены к соответствующим гран м смежных секций оболочки, а подколонник установлен враспор между наклонными гран ми секций оболочки и угол наклона его боковых граней равен углу на1клона обращенных к ним гоаней секций оболочки.This goal is achieved by the fact that the foundation under the column, which includes a shell placed in the ground, a composite section consisting of vertical sections, in which a sub-column is placed, which has inclined side faces, is provided with a support plate on which the shell sections are installed; each section is made in the form of a volume block, one side face of which is made inclined towards the vertical axis of the basement and faces the sub-column, two are made vertical and face is facing the ground, and the other two are vertical and face the corresponding faces of the adjacent shell sections installed between the inclined edges of the shell sections and the angle of inclination of its side faces is equal to the angle of inclination of the legs of the shell sections facing them.

Claims

In this case, the central part of the base plate can be made with an upwardly thickening, on which inclined side faces of the shell sections are supported. FIG. 1 shows the interrupted, lagged foundation, transverse cut. on. FIG. 2 - the same in terms of. The foundation includes a base plate with a thickening of 2 in the central part, the shell and column made up of vertical sections. On the edges of the plate 1 along the perimeter and on its thickening 2, sections 3 of the shell and their ribbed outer vertical walls 5 and 6 are respectively facing each other and to the ground of base 1. The middle walls 8 of the shell section 3 have a downward slope and are perpendicular to the diagonal ribs 9, in a junction with a squam cup. In the cavity of this glass a wedge-shaped column is placed with a glass of 10 under the column. The outer walls 6 of the shell sections 3 have a height greater than all the other walls by an amount of thickening 2 of the slab 1, which allows the shells of the shell 3 to be supported on the edges of the slab 1. The foundation is installed as follows. In the preparatory pit in the soil base 7 set the base plate 1, and on it section 3 of the shell. A through-glass, formed by the walls 8 of section 3, is installed with thrusting under-column k with one hundred ca 10 under the column. The gap between the cup 10 and the column is filled with monolithic concrete 11. The load from the column is transferred through sub-column k to section 3 of the envelope. In this case, the foundation transmits the load not only through the base plate 1-, but also through the vertical walls 6 of the shell due to the wedging of section 3 with a sub-column. As a result, the bearing capacity of the foundation is increased. 8 The use of the proposed foundation significantly reduces the consumption of materials during the construction of a zero cycle of buildings and structures. Claim 1. The foundation for a column, comprising a shell placed in the ground, a subtitle composed of vertical sections, in which a sub-column is placed, having inclined side faces, characterized in that, in order to reduce the labor intensity of foundation construction, it is provided with a base plate on which the shell sections are installed , each section is made in the form of a volume block, one side face of which is inclined towards the vertical axis of the foundation and facing the sub-column, two are made vertical and facing the untu base and the other two formed by vertical and facing the corresponding face of m adjacent shell sections, and podkolonnik vraspor installed between the inclined faces of the Sheath sections and angle of its lateral faces is equal to the angle of inclination of faces facing thereto shell sections. 2. A foundation according to claim 1, characterized in that the central part of the base plate is made with an upwardly directed thickening on which the inclined side faces of the shell sections are supported.
