(54) METHOD OF MANUFACTURING PANELS FROM LIGHT CONCRETE

one

The invention relates to the production of panels from lightweight concrete, it can be used in the construction industry.

There are known methods for producing panels by laying light and heavy concrete into a form with their subsequent compaction 1.

However, the existing method of manufacturing panels does not ensure their reliability during transportation, installation and storage, since the edges of the panels are chipped due to the fact that these panels do not have a frame of more durable concrete.

The closest to the proposed technical essence and the achieved effect is a method of manufacturing panels of lightweight concrete with a core of aerated concrete, enclosed in a frame of high-strength concrete, by installing partition walls on the form tray pc1Mku with their subsequent compaction 12. The known method of manufacturing panels of lightweight concrete does not provide for an increase in productivity and an improvement in the adhesion of the aerated concrete of the core with ETOH frame, as in s.mesey laying concrete core and is produced in a frame sequentially. First laid aerated concrete. core, and then put high-strength concrete in the frame. Due to the sequential laying during setting of concrete mixtures in the core and

0 in the frame there is a failure of adhesion of concrete to aerated concrete, as well as reduced productivity of the unit and lengthened the cycle of manufacturing products.

The aim of the invention is to increase the productivity of the processing line and improve the adhesion of the aerated concrete of the core to the reinforced concrete contour of the frame, a significant

0 product quality improvement.

The goal is achieved by the fact that the laying of concrete mixtures in the core and the frame is carried out simultaneously, and the dividing partition

5 ki are removed from the mixture during the molding process before the end of compaction.

Dividing partitions are placed on the form pallet, then the concrete mixes are simultaneously laid in the core and in the frame. At the same time, a gas-concrete mixture is laid in the core, and high-strength mixture, for example, expanded clay concrete, is framed. Ceramsite is used with a strength of 200-300 kg / cm. Next, concrete mixes are compacted, and the dilatation walls are removed during the molding process before the end of compaction. It is preferable to remove the baffles during the molding process 5-10 seconds before the end of the seal.
