Description

Изобретение относитс  к строительной индустрии , а именно к производству бетонных и железобетонных изделий.The invention relates to the construction industry, namely the production of concrete and reinforced concrete products.

Известны способы изготовлени  бетонных и железобетонных изделий путем вибропр ессовани  и отсоса избыточной воды с одной из поверхностей издели . Однако при изготовлении бетонных и железобетонных изделий известным способом отсос воды производитс  не со всей толщины издели , а лишь с незначительной толщины сло  бетонной смеси.Methods are known for the manufacture of concrete and reinforced concrete products by vibropressing and sucking off excess water from one of the surfaces of the product. However, in the manufacture of concrete and reinforced concrete products in a known manner, water suction is not performed from the entire thickness of the product, but from only a small thickness of the concrete mix layer.

Цель изобретени  - устранение указанного недостатка.The purpose of the invention is to eliminate this drawback.

Дл  этого после вибропрессовани  производ т нагревание издели  через ее поверхность , противоположную подвергаемой отсасыванию .To do this, after vibropressing, the product is heated through its surface opposite to that which is subjected to suction.

Сущность способа заключаетс  в следующем .The essence of the method is as follows.

При изготовлении плоских изделий (без пустот) на дно формы устанавливают прессующее устройство с нагревательными элементами . После заполнени  формы поверх бетонной смеси устанавливают плиту из абсорбирующего материала. Поверх абсорбирующей плиты устанавливают жесткую плиту и скрепл ют ее с формой. Подготовленную таким образом форму устанавливают на вибростол . Затем включают прессующее устройство, нагревательные элементы и вибростол.In the manufacture of flat products (without voids) at the bottom of the form set pressing device with heating elements. After filling the molds, a slab of absorbent material is placed on top of the concrete mix. A rigid plate is placed on top of the absorbent plate and secured to the mold. The form prepared in this way is installed on the vibrating table. Then include a pressing device, heating elements and a vibrating table.

Под действием вибрации и давлени  бетонна  смесь равномерно заполн ет объем формы и унлотн етс , а в результате нагрева ни  избыточна  вода в бетонной смеси будет перемещатьс  по капилл рам от более нагретых мест к менее нагретым, т. е. от поверхности, на которой расположены нагревающие элементы , к поврехности, на которой остановлена абсорбирующа  плита, т. е. избыточна  вода ликвидируетс  практически со всей толщины Under the action of vibration and pressure, the concrete mix uniformly fills the volume of the mold and is compacted, and as a result of heating, no excess water in the concrete mix will move through the capillaries from the more heated places to the less heated ones, i.e. from the surface on which the heating elements are located. elements, to the surface where the absorbing plate is stopped, i.e. excess water is eliminated from almost the entire thickness

0 издели .0 products.

Вместо вибростола можно использовать глубинные вибраторы. В этом случае абсорбирующую плиту устанавливают на дно формы , а прессующее устройство с нагреватель5 ными элементами устанавливают новерх издели  после виброуплотнени .Instead of a vibrating table, deep vibrators can be used. In this case, the absorbent plate is placed on the bottom of the mold, and the pressing device with heater elements is installed on top of the product after vibration compaction.

При изготовлении изделий с пустотами абсорбирующие плиты устанавливают на дно формы или по периметру формы, а пустотообразователн  вл ютс  одновременно нрессук/ще-нодогревательнымп устройствамн.In the manufacture of products with voids, absorbent plates are placed on the bottom of the mold or around the perimeter of the mold, while the hollow cores are simultaneously the pressure / squat-heating devices.

Предмет изобретени Subject invention

Способ изготовлени  бетонных и железобетонных изделий путем вибронрессованн  и отсоса избыточной воды с одной нз поверхностей издели , отличающийс  тем, что, с целью ликвидации избыточной воды со всей 3 толщины издели , после вибропрессовани  производ т нагревание издели  через поверх4 ность, противоноложную подвергаемой отсасыванию .A method of manufacturing concrete and reinforced concrete products by vibro-pressed and suctioning excess water from one of the product surfaces, characterized in that, in order to eliminate excess water from the entire thickness of the product 3, after vibropressing, the product is heated through a surface that is opposed to being subjected to suction.
