E 02 D 27/01, 2006, adopted by the applicant for the prototype. It contains metal elements and parts, a horizontal support element and vertical stiffeners fixed on it from above, supporting the support parts installed above for the structures of the aerial part of the building.

Однако, такой фундамент имеет сложную, насыщенную металлом конструкцию, не дающую основание утверждать о достаточности его несущей способности.However, such a foundation has a complex, metal-saturated design, which does not give reason to assert the adequacy of its bearing capacity.
Технической задачей изобретения является упрощение конструкции, снижение металлоемкости и повышение несущей способности возводимого под колонну, опору, мачту, опору линии электропередач малозаглубленного фундамента на естественном или искусственном основании, в том числе при устройстве ленточных или столбчатых фундаментов.An object of the invention is to simplify the design, reduce metal consumption and increase the bearing capacity of a column under construction, a support, a mast, a support of a power line of a shallow foundation on a natural or artificial foundation, including the construction of strip or column foundations.
Поставленная задача решается тем, что в предлагаемом техническом решении опорная часть снабжена нижней и верхней арматурными сетками, а рёбра жёсткости
размещены в виде, по меньшей мере, трёх лучей, выходящих из одного центра, находящегося на вертикальной оси фундамента, выполнены в виде гнутых профилей и снабжены элементами жёсткости, причём рёбра жёсткости установлены между нижней и верхней арматурными сетками, а элементы присоединения конструкции колонны к фундаментной части выполнены в виде арматурных выводов.The problem is solved in that in the proposed technical solution, the support part is provided with lower and upper reinforcing meshes, and stiffeners placed in the form of at least three rays extending from one center located on the vertical axis of the foundation, made in the form of bent profiles and provided with stiffeners, with stiffening ribs installed between the lower and upper reinforcing meshes, and elements connecting the construction of the column to the foundation parts are made in the form of reinforcing conclusions.
Кроме того, гнутый профиль ребра жёсткости выполнен в виде синусоиды, а элементы жёсткости установлены вдоль каждого ребра жёсткости попарно с двух сторон.In addition, the bent profile of the stiffener is made in the form of a sinusoid, and stiffeners are installed along each stiffener in pairs from two sides.
На фиг. 1 изображён общий вид фундамента под колонну с присоединенной колонной; на фиг. 2 - размещение рёбер жёсткости в фундаменте, вид в плане; на фиг. 3 - ребро жёсткости в виде гнутого профиля с элементами жёсткости; на фиг. 4 - гнутый профиль ребра жёсткости в виде синусоиды.In FIG. 1 shows a General view of the foundation under the column with an attached column; in FIG. 2 - placement of stiffeners in the foundation, plan view; in FIG. 3 - stiffener in the form of a bent profile with stiffeners; in FIG. 4 - curved profile of the stiffener in the form of a sinusoid.
На фигурах 1 и 2 металлические конструкции условно показаны не залитыми бетонной массой.In figures 1 and 2, metal structures are conventionally shown not flooded with concrete mass.
Фундамент под колонну содержит опорную часть и подколонную часть. В опорной части размещены: нижняя 1 и верхняя 2 арматурные сетки и рёбра жёсткости 3, а в подколонной части установлены арматурные выводы 4, служащие элементами присоединения конструкции колонны 5 к фундаменту.The base for the column contains a support part and a column part. In the supporting part there are: lower 1 and upper 2 reinforcing meshes and stiffening ribs 3, and reinforcing leads 4 are installed in the annular part serving as connecting elements of the column structure 5 to the foundation.
Рёбра жёсткости 3 выполнены в виде гнутого профиля и снабжены элементами жёсткости 6, которые установлены вдоль каждого ребра жёсткости 3 попарно с двух сторон, по меньшей мере, по верхнему и нижнему торцам.The stiffening ribs 3 are made in the form of a bent profile and are equipped with stiffening elements 6, which are installed along each stiffening ribs 3 in pairs from two sides, at least along the upper and lower ends.
Гнутый профиль ребра жёсткости 3 может быть представлен несколькими видами кривых, например: в виде синусоиды, прямоугольника, трапеции, треугольника и других подобных фигур. А элементы жёсткости 6 могут быть выполнены, например: из арматуры, прутка, полосы, уголка или швеллера и им подобных. Крепление элементов жёсткости 6 с ребром жёсткости 3 осуществляют посредством, например: контактной сварки, вязальной проволоки, сквозных хомутов или других крепёжных элементов.The bent profile of the stiffener 3 can be represented by several types of curves, for example: in the form of a sinusoid, rectangle, trapezoid, triangle and other similar shapes. And stiffening elements 6 can be made, for example: from reinforcement, bar, strip, angle or channel and the like. The fastening of stiffeners 6 with stiffener 3 is carried out by, for example: resistance welding, knitting wire, through clamps or other fasteners.
Рёбра жёсткости 3 симметрично размещены в виде, по меньшей мере, трёх лучей, выходящих из одного центра, находящегося на вертикальной оси фундамента и установлены между нижней 1 и верхней 2 арматурными сетками на ребро в направлении от вертикальной оси фундамента. Для минимального обеспечения несущей способности фундамента в опорной части может быть установлено, по меньшей мере, три ребра жёсткости 3. Но, в зависимости от степени ответственности сооружения, количество
рёбер жёсткости 3 может быть увеличено. Это дает возможность выбора количества рёбер жёсткости, в отличие от прототипа, где конструкция опорной части постоянна и металлоемка, тем самым упрощая конструкцию и снижая металлоемкость сооружения, не снижая несущей способности.The stiffening ribs 3 are symmetrically placed in the form of at least three rays emerging from one center located on the vertical axis of the foundation and installed between the lower 1 and upper 2 reinforcing meshes on the rib in the direction from the vertical axis of the foundation. To minimize the bearing capacity of the foundation, at least three stiffeners 3 can be installed in the supporting part 3. But, depending on the degree of responsibility of the structure, the number stiffening ribs 3 can be increased. This makes it possible to choose the number of stiffeners, in contrast to the prototype, where the construction of the supporting part is constant and metal-intensive, thereby simplifying the structure and reducing the metal consumption of the structure, without reducing the bearing capacity.
Возводят фундамент следующим образом.The foundation is erected as follows.
Сначала подготавливают площадку под опорную часть, выставляя опалубку по окружности, так как фундамент возводят, например, круглый, например, под круглую колонну 5. Для этого укладывают нижнюю арматурную сетку 1 на подготовленную площадку. На нее устанавливают подготовленные заранее рёбра жёсткости 3, ориентируя их относительно вертикальной оси фундамента. Сверху на установленные рёбра жёсткости 3 размещают верхнюю арматурную сетку 2. Затем жестко скрепляют арматурные сетки 1 и 2 с рёбрами жёсткости 3 и вертикально устанавливают арматурные выводы 4 для присоединения конструкций колонны 5.First, prepare the site for the supporting part, exposing the formwork around the circumference, since the foundation is erected, for example, round, for example, under a round column 5. To do this, lay the bottom reinforcing mesh 1 on the prepared site. On it set in advance prepared stiffening ribs 3, orienting them relative to the vertical axis of the foundation. The upper reinforcing mesh 2 is placed on top of the installed stiffening ribs 3. Then, the reinforcing meshes 1 and 2 are rigidly fastened with stiffening ribs 3 and the reinforcing leads 4 are vertically mounted for connecting the column structures 5.
Смонтировав всё перечисленное, заливают бетоном собранную конструкцию. По достижении опалубочной прочности, снимают опалубку и фундамент готов к дальнейшим монтажным работам.Having mounted all of the above, pour the assembled structure with concrete. Upon reaching the formwork strength, the formwork is removed and the foundation is ready for further installation work.
Использование предлагаемого технического решения позволило упростить конструкцию, снизить металлоёмкость и повысить несущую способность возводимого под колонну, опору, мачту, опору электропередач малозаглубленного фундамента на естественном или искусственном основании, в том числе при установке ленточных или столбчатых фундаментов.
