SU115641A1 - Plant for the manufacture of large concrete and reinforced concrete blocks - Google Patents

Description

Known installations for the manufacture of large-sized blocks using vibrating plates or vibrating inserts,

In the manufacture of a block on a vibroplatform, the concrete is shaved together with the mold, which necessitates an increase in the power of the vibrators and energy consumption.

In the manufacture of a block using vibrating inserts, as well as on the vibrating plate, the concrete is compacted by the particles settling under the influence of vibration, which does not provide the necessary compaction of hard concrete, especially in the manufacture of thin-walled blocks.

The present invention proposes a plant for the manufacture of blocks with layer-by-layer bedding and vibration of a concrete mix, thus eliminating the above disadvantages.

The drawing shows the installation (in a perspective view), a general view. The installation consists of a table / reciprocating; dispensers 2, located on two opposite sides of the table /; hooks 3 for dispensers 2 toothed racks 4 attached to the frame of table 1 on two opposite sides of it; drive mechanisms 5 transmitting the movement of the table to the table by electric motors through gearboxes and gears which engage with the toothed rails 4; vibromechanisms 6. The raising and lowering of vibromechanisms is carried out using a device 7 consisting of an electric motor, which drives a shaft with two sprockets located at its ends through a gearbox. The stars Gal are put on the sprockets connected at one end with the upper frame of the vibromechanism (in the drawing the springs of the second mechanism are not shown).

The device 8 is intended for placing the concrete mixture into the dispensers 2. The device 8 is located in the center of the installation above the table and consists of a metal box made to the size of the dispenser 2

No. 115641 - 2-

with a knife on the bottom edge. The concrete mixture is fed to the device 8 from the vibrating tank R.

The device 10 serves to loosen the concrete mix in the metal box of the device 8. The device 10 consists of two shafts with asterisks on which the Gal chains are put on; Steel fingers, made in the form of a rake, equal to the height of the crate of the device 8, are attached to the last ones. The rake, continuously moving in both directions, loosened the concrete mix, which facilitates uniform filling of concrete into the dispenser 2. The device 10 is placed above the device 8 and is provided in motion by the electric motor 11 through the gearbox.

All installation units are mounted on a rigid frame 12 made of metal.

The operation of the installation is performed in the following sequence.

At the time of installation of the dispenser 2 above the form A, the dispenser located on the opposite side of the table 1 receives the concrete mixture from the device 5, and in the form B at this time the device 6 vibrated in the form of the concrete mixture layer. After the dispenser 2 is loaded with a concrete mixture, the table / moves towards Form B, at the same time with device 7, the vibrating mechanism 6 above Form B rises up and the vibrating mechanism above Form A is lowered into the form to compact the concrete layer. From the dispenser 2 into the form B, the next layer of the concrete mix is placed on the compacted layer of concrete and at the same time the concrete mix from the device 8 enters the dispenser located on the opposite side of the table J.

Thus, the cycles of layering the concrete mixture of layered vibration are repeated until the blocks are completely manufactured.
