(54) СПОСОБ ФОРМОВАНИЯ СТРОИТЕЛЬНЫХ ИЗДЕЛИЙ ИЗ ШСТКИХ БЕТОННЫХ СМЕСЕЙ(54) METHOD OF FORMING CONSTRUCTION PRODUCTS FROM STEEL CONCRETE MIXTURES

Изобретение относитс к технике заводского производства строительных бетонных и железобетонных изделий методом проката.The invention relates to a factory production technique of building concrete and reinforced concrete products by rolling.

Известны способы формовани строительных изделий из жестких бетонных смесей в формах с одной открытой поверхностью путем подачи бетонной смеси под р д одинаковых, параллельных друг другу, свободно вращающихс на ocsnc роликов, соприкасакидихс с открытой поверхностью формуемого издели и перемшцаемых относительно открытой поверхности формы в поперечном продольном направлени х.Methods are known for forming construction products from rigid concrete mixtures in forms with one open surface by feeding the concrete mixture under a series of identical, parallel to each other, freely rotating rollers on the surface, in contact with the open surface of the molded product and displaced relative to the open surface of the mold in the transverse longitudinal direction x

Однако такие способы не гарантируют высокого качества формуемых изделий.However, such methods do not guarantee high quality molded products.

Цель изобретени - повышение качества уплотнени бетонной смеси.The purpose of the invention is to improve the quality of compaction of the concrete mix.

Это достагаетс тем, что бетонную смесь подают под ролики слоем, превышающим толщину формуемого издели под роликом, измер емую перпендикул рно к открытой поверхности формуемого изделиThis is achieved by the fact that the concrete mixture is fed under the rollers with a layer exceeding the thickness of the molded product under the roller, measured perpendicular to the open surface of the molded product.

не более чем на величину, необходимую дл зат гивани под ролик всех частиц бетонной смеси, расположенных выше открытой поверхности издели . Скорость пе ремещени роликов вдоль осей выбирают в зависимости от скорости перемещени сло бетонной смеси, аи да вливаемого изпод передних торцов роликов по ходу их перемеще ш вдоль оси. Кроме того, скорость поперечного перемещени роликов привод т в соответствие со скорост ми подачи бетонной смеси и продольного перемещени роликов, так что врем продвижени неуплотненной бетонной смеси между роликами от одннх торцов до других превьинает врем перемеще1ш роликов на величину, равную расстогнию между смежными роликами в зоне падени бетонной смеси.no more than the amount required to tighten all the concrete particles above the open surface of the product under the roller. The speed of movement of the rollers along the axes is chosen depending on the speed of movement of the layer of concrete mix, and the amount of pouring from the front of the front ends of the rollers along their movement along the axis. In addition, the speed of transverse movement of the rollers is adjusted to the speed of the concrete mix and the longitudinal movement of the rollers, so that the advancement of the unconsolidated concrete mix between the rollers from one end to the other extends the movement of the rollers by an amount equal to the distance between adjacent rollers in the area falling concrete mix.

Claims

The proposed method is illustrated in drawing. cross} x 1 shaft edge of the form, and begin to continuously mix the axis of the rollers across the form. Then the concrete mixture is continuously fed into the space between the mold and the rollers and the rollers begin moving along the mold, while the concrete mix is delivered in such a way that the ends of the rollers are always covered with concrete and supported. When the rollers go up the mold, the concrete mix stops flowing off, and the excess is dumped onto the molding table 4. A new mold is installed in place of the molded mold, the rollers move it to the beginning, where the concrete mix is dropped from the molding table and the axes start to move Rollers across the rivers of form. The process is repeated. The concrete mixture is fed under the rollers with a layer exceeding the thickness of the moldable product 5 under the roller, measured perforally to the open surface of the article to be produced, no more than: y1 by the amount necessary to tighten all the concrete mixture below the open surface under the roller products. The speed of movement of the rollers along their axes is chosen depending on the speed of movement of the layer of concrete mix, which is pressed from under the front tornas of the rollers along their movement along the axis. Claim 1. Method of forming construction products of hard concrete mixes in forms with one open surface by feeding concrete mix under the same uniform, parallel to each other freely rotating rollers on the axes, contact of the molded product and moving relative to the open surface of the mold in the transverse and the longitudinal direction 5 X, characterized in that, in order to improve the quality of compaction, the concrete mixture is fed under the rollers with a layer that makes it possible to thickness the molded article A roller, measured perpendicularly to the OPEN surface of the molded product, is no more than the height required to pull all the concrete mixture particles located above the open surface of the product under the roller, and the speed of movement of the rollers along their axes is chosen depending on the speed of movement a layer of concrete mixture, squeezed out from under the front ends of the rollers as they move along the axis.

2. The method according to claim 1, wherein in order to avoid spilling the concrete mixture between the rollers, the speed of transverse movement of the rollers is adjusted to the speeds of the concrete mixture and the longitudinal movement of the rollers so that the travel time of an unconsolidated concrete mix between the rollers from the full ends to the others exceeds the travel time of the rollers by an amount equal to the distance between the adjacent rollers in the falling zone of the concrete mix.
