Abstract

FIELD: construction.SUBSTANCE: invention relates to construction and can be used in construction of road and railway overpasses, overpass for process pipelines. Trestle supports forming method in the construction conditions, in which the reinforcement is installed into the core mold. Concrete mixture is supplied with its further vibrocompression by introduction of vibrating bench with perforation of its working surface. Annular cavity is formed between the vibration rod and the core. Annular cavity is equipped with filtering material. Core is perforated to form a vacuum cavity and subsequent evacuation of the concrete. After concrete set of sufficient strength, the mold is disassembled.EFFECT: technical result is higher reliability and durability of overpasses.3 cl, 1 dwg

Description

Изобретение относится к строительству и может быть применено при устройстве автомобильных и ж/д эстакад, а также эстакад под технологические трубопроводы Известен способ формования трубчатых изделий из бетонных смесей /а.с. №1816265/.The invention relates to the construction and can be applied at the device of automobile and railway racks, as well as racks for technological pipelines. There is a known method of forming tubular products from concrete mixtures / a.s. No. 1816265 /.

К недостаткам способа возможно отнести недостаточную область применения, низкую надежность и долговечность.The disadvantages of the method may include insufficient scope, low reliability and durability.

Известно также Устройство для изготовления трубчатых изделий содержащее установку в форму с сердечником арматуры и подачу бетонной смеси с последующем виброштампованием путем внедрения виброштампа с перфорацией его рабочей поверхности и образованием между ним и сердечником кольцевой полости. /а.с. №2047485/. К недостаткам устройства возможно отнести невысокое качество и долговечность изготовления изделия. Цель изобретения - повышение производительности сборки изделия в построечных условиях, поышение качества устройства опор. Предлагаемым решением опора возводится в следующем порядке. На фундамент, преимущественно сваю-оболочку, устанавливается форма с сердечником с образованием кольцевой полости заполненной фильтрующим материалом, а сердечник выполняют с перфорацией с образованием вакуум-полости и вакуумированием бетона, причем извлечение сердечника и виброштампа производят одновременно с подачей в форму несвязного сыпучего материалам после набора бетоном требуемой прочности форму разбирают. Конечно-же предлагаемую опору желательно ставить на сваю-оболочку, верх которой заполняют бетоном одновременно с подачей бетона внутрь опоры.It is also known Device for the manufacture of tubular products containing the installation in a form with a core of reinforcement and the flow of concrete mix with the subsequent vibration stamping by introducing a vibrostamp with perforation of its working surface and the formation of an annular cavity between it and the core. / a.s. No. 2047485 /. The disadvantages of the device may include low quality and durability of the product. The purpose of the invention is to improve the performance of the Assembly of the product in construction conditions, increase the quality of the device supports. The proposed solution builds in the following order. A foundation with a core is formed on the foundation, mainly a pile shell, with the formation of an annular cavity filled with filtering material, and the core is perforated to form a vacuum cavity and concrete is evacuated, and the core and vibrostamp are removed simultaneously with feeding into the form of loose material. Concrete strength required form disassemble. Of course, the proposed support should preferably be placed on a pile-shell, the top of which is filled with concrete simultaneously with the supply of concrete into the interior of the support.

Способ поясняется чертежом. На фундамент 1, преимущественно сваю оболочку, устанавливается форма 2 с перфорацией/не показано/и сердечником 3 и подается арматура 4 и бетон 5, внедрение виброштампа 6 с образованием кольцевой полости 7 снабженной фильтрующим материалом/не показано/. После чего в сердечнике 3 создают вакуум, который позволяет отобрать у бетона свободную воду затворения. После завершения вакуумирования производят удаления виброштампа и сердечника производят подачу сыпучего материала 8, до подачи последнего может быть выполнена бетонная пробка 9, а форму 2 разбирают после набора требуемой прочности бетона. Предлагаемое решение при его использовании позволит ускорить процесс и повысить МРЗ и прочность бетона.The method is illustrated in the drawing. On the foundation 1, mainly a pile shell, a form 2 is installed with perforations / not shown / and core 3 and fittings 4 and concrete 5 are fed in, the introduction of a vibrating stamp 6 with the formation of an annular cavity 7 provided with filtering material / not shown /. Then in the core 3 create a vacuum, which allows you to take away the concrete free mixing water. After the completion of the vacuuming, the vibrostamp is removed and the core is used to deliver bulk material 8, before the latter can be supplied, concrete block 9 can be made, and form 2 is disassembled after the required concrete strength has been obtained. The proposed solution for its use will speed up the process and increase the IDA and the strength of concrete.
