Description

Предложен способ изотовлени  плит и других изделий из  чеистых бетонов с более плотным поверхностным слоем из того же материала, что и все изделие.A method for the fabrication of slabs and other articles of cellular concrete with a more dense surface layer of the same material as the entire product has been proposed.

По сравнению с ранее известным прокатным способом изготовлени  бетонных и железобетонных изделий предложенный способ позвол ет упростить технологию изготовлени  панелей и других изделий с одновременным улучшением их физико-механических свойств за счет сминани  в начале твердени  поверхностного сло  залитого в форму  чеистого бетона, например, прокатыванием валика по бетону.Compared with the previously known rolling method of manufacturing concrete and reinforced concrete products, the proposed method allows us to simplify the manufacturing technology of panels and other products while simultaneously improving their physicomechanical properties due to crushing at the beginning of the hardening of the surface layer of cellular concrete poured into the form, for example, rolling to concrete.

В зависимости от состава и температуры  чеистый бетон через 2- 8 час после заливки в форму начинает твердеть. В это врем  открытую сверху формы поверхность издели  сминают, например, прокатыванием валиком. Во врем  прокатывани  валик давит на малую часть площади издели  и за счет этого сминает и уплотн ет поверхностный слой издели .Depending on the composition and temperature, cellular concrete starts to harden after 2-8 hours after pouring into the mold. At this time, the top-opened surface of the product is crushed, for example, by rolling with a roller. During rolling, the roller presses against a small part of the product area and thereby crushes and seals the surface layer of the product.

Дл  осуществлени  предложенного способа можно: а) нарастить борта форм на 2-5 см, затем залить  чеистый бетон, в начале твердени  нарощенную часть бортов сн ть и верхний слой издели  см ть. В зависимости от высоты нарощенных бортов получают уплотненный слой требуемой толщины.To implement the proposed method, it is possible to: a) build up the sides of the molds by 2-5 cm, then pour cellular concrete, at the beginning of hardening, the expanded part of the sides should be removed and the upper layer of the product should be removed. Depending on the height of the increased sides, a compacted layer of the required thickness is obtained.

б) Ячеистый бетон заливают до бортов формы и в начале твердени  прокатывают валиком в двух взаимно-перпендикул рных направлени х , благодар  чему у бортов не остаютс  непрокатанные участки. Мен   диаметр валика, получит требуемую толщину уплотненного сло .b) Cellular concrete is poured to the sides of the mold and, at the beginning of hardening, is rolled in two mutually perpendicular directions, due to which there are no non-rolled sections on the sides. The diameter of the roller, will receive the required thickness of the compacted layer.

Например, при уплотнении сло , выступающего над бортами формы на 1 см, после сн ти  нарощенной части бортов получаетс  уплотненный слой издели  в 1,5-2 см.For example, when compacting a layer protruding 1 cm above the bead, after removing the enlarged part of the beads, a compacted product layer of 1.5-2 cm is obtained.

На фиг. 1 изображена схема осуществлени  предложенного способа при применении наращивани  бортов (вариант а); на фиг. 2 - то же. при применении валиков, опирающихс  на борта формы (вариант б).FIG. 1 shows the scheme for carrying out the proposed method when applying the bead augmentation (variant a); in fig. 2 - the same. when using rollers resting on the bead of the mold (option b).

В форму / с нарощенными бортами 2 или без них заливают  чеистый бетон 3, который в начале твердени  сминают валиком 4, получа  уплотненный слой 5.Cellular concrete 3 is poured into the form / with or without extended sides 2, which is crushed with a roller 4 at the beginning of hardening to obtain a compacted layer 5.

Предмет изобретени Subject invention

Способ изготовлени  плит и других изделий из  чеистых бетонов с более плотным поверхностным слоем, отличающийс  тем, что дл  создани  уплотненного поверхностного сло  из того же материала, что и все изделие, с целью упрощени  технологии изготовлени  панелей, а также улучщени  их физико-механических свойств, поверхностный слой залитого в форму  чеистого бетона сминают в начале твердени , например , прокатыванием валика по бетону.A method of manufacturing plates and other products from cellular concrete with a more dense surface layer, characterized in that in order to create a compacted surface layer of the same material as the entire product, in order to simplify the technology for the manufacture of panels, as well as to improve their physico-mechanical properties, The surface layer of the cellular concrete poured into the mold is crushed at the beginning of hardening, for example, by rolling a roller over the concrete.
