Description

Изобретение относится к области строительства железобетонных преднапрягаемых корпусов высокого давления, предназначенных для физико-химических и энергетйчес- ких процессов, и в частности, к области возведения опорных конструкций, обеспечиваю- ⁵щих скольжение корпуса по опоре.The invention relates to the field of construction of reinforced concrete pre-stressed high-pressure casings intended for physicochemical and energy processes, and in particular, to the field of erection of supporting structures providing ⁵ sliding of the housing along the support.

Известна опорная конструкция и способ ее возведения, при котором подливка цементным или другим уплотняющим раствором осуществляется под опорные части, закрепленные к полностью смонтированной конструкции, например, к мостовому пролетному строению. В этом случае загружение опорных частей выполняют с помощью гидравлических домкратов, объединенных в единую гидравлическую систему [1]. ¹⁵ A support structure and a method of erecting it are known in which pouring with cement or other sealing mortar is carried out under support parts fixed to a fully mounted structure, for example, to a bridge span. In this case, the loading of the supporting parts is performed using hydraulic jacks, combined into a single hydraulic system [1]. ^fifteen

Наиболее близкой к предложенному изобретению является опорная конструкция кор- , пуса высокого давления, включающая радиальные ребра и опорные части, имеющие фиксирующие листы с анкерами, причем они го выполнены из свинца, и способ возведения опорной конструкции корпуса высокого давления, включающий изготовление радиальных ребер, заполнение бетонной смесью опа лубки, соединение их с опорными частями и выдержку бетонной смеси до приобретения ей расчетной прочности [2].Closest to the proposed invention is the supporting structure of the housing, the high pressure sleeve, including radial ribs and supporting parts having fixing sheets with anchors, and they are made of lead, and a method of erecting the supporting structure of the high pressure housing, including the manufacture of radial ribs, filling concrete formwork mixture, their connection with the supporting parts and exposure of the concrete mixture to its design strength [2].

Недостатками данного технического решения является то, что известные конструкции и способы решают задачу возведения опорных конструкций при сравнительно незначительных размерах опорных частей и их поверхностей (рабочих) порядка 1-1,5 м². Кроме того, подливка цементным раствором опорных частей больших размеров не обеспечивает плотного и повсеместного заполнения пространства под ними, анкеровка опорных листов несущей конструкции крайне затруднительна, а фиксация всех опорных листов в одной плоскости известными способами не гарантирована.The disadvantages of this technical solution is that the known structures and methods solve the problem of erecting supporting structures with relatively small sizes of the supporting parts and their surfaces (working) of the order of 1-1.5 m ² . In addition, the cement slurry of the supporting parts of large sizes does not provide a dense and ubiquitous filling of the space under them, the anchoring of the supporting sheets of the supporting structure is extremely difficult, and the fixing of all the supporting sheets in one plane by known methods is not guaranteed.

Относящиеся к известным конструкциям и способам метод инъекций под опорные части твердеющего раствора имеет' те же недостатки, усугубляющиеся тем, что поверхности скольжения опорных частей должны быть выполнены по высокому классу точности, что не допускает устройства в них контрольных или каких-либо других отверстий.The injection method for the supporting parts of the hardening mortar, which relates to known constructions and methods, has the same drawbacks, which are aggravated by the fact that the sliding surfaces of the supporting parts must be made to a high accuracy class, which prevents the installation of control or any other holes in them.

Кроме того, выверку и фиксацию опорных частей осуществляют в трех точках каждой опорной части, причем эти точки расположены не на одной прямой, а выверку и размещение опорных рабочих поверхностей в горизонтальной плоскости контролируют водомерами, закрепленными к каждой опорной части в трех точках, расположенных не на одной прямой.This '''' is achieved by the fact that in the supporting structures of the high-pressure casing, including radial ribs and supporting parts having fixing sheets with anchas, SD is made in the form of a rectangular reinforced concrete beam with side edges chamfered in the lower part, into which fiksiruyuankerami concreted and provided with radial ribs ^ rebar, p1snnymi posted in locations of anchors _and connected thereto, wherein the gap between 'the radial ribs and the supporting portions concreted, and in the method of erecting the support Konstr ktsii high giving body. ---- - 'Deitsya;' including the production of radial ribs, filling the formwork with concrete mixture, joining them with the supporting parts and holding the concrete mixture to its design strength, first radial ribs are made, after which, on the horizontal plane verified, the formwork of the support part is mounted, fixing sheets with anchors are installed, formwork is poured concrete mixture and withstand until the concrete acquires the design strength, then the supporting parts are turned into the working position, fixed on the supporting ribs and verified with as _{: the} position of the working surfaces of the radial bearings in the same plane, after which the bearing parts are monochromatic with the supporting ribs. In addition, the alignment and fixation of the supporting parts is carried out at three points of each supporting part, and these points are not located on one straight line, and the alignment and placement of the supporting working surfaces in a horizontal plane is controlled by water meters fixed to each supporting part at three points located not on one straight line.

Опорные части опорной конструкции кор5 пуса высокого давления изготавливают в стороне в перевернутом положении, причем лист рабочей поверхности 3 с анкерами 4 укладывают и закрепляют на выверенной поверхности 5, после чего монтируют опалубку опорной части и бетонируют ее. После ¹⁰ приобретения бетоном необходимой прочности, опорную часть извлекают из опалубки и, повернув рабочей поверхностью вверх, монтируют над заранее забетонированными радиальными ребрами, закрепив опорную is часть к трем винтам 6 рихтовочного устройства 7, одновременно присоединив к опорной части водомеры. 8.The supporting parts of the supporting structure of the high-pressure housing are made to the side in an inverted position, and the sheet of the working surface 3 with anchors 4 is laid and fixed on the calibrated surface 5, after which the formwork of the supporting part is mounted and concreted. After ¹⁰ acquiring the necessary strength by concrete, the supporting part is removed from the formwork and, turning the working surface up, mounted above the pre-concreted radial ribs, fixing the supporting part to the three screws 6 of the leveling device 7, while simultaneously connecting the water meters to the supporting part. 8.
