Abstract

The invention relates to the field of manufacturing precast concrete and reinforced concrete products and reduces the labor intensity of the stripping. In the form for the manufacture of centrifuged concrete products, the pallet 3 and the cross section of each forming compartment are trapezoidal. The larger base of the cross section of the molding section faces the pallet 3. 2 Il.

This invention relates to the manufacture of precast concrete and reinforced concrete products.

The aim of the invention is to reduce the labor intensity of the stripping.

FIG. Figure 1 shows schematically a composite form for the manufacture of centrifuged tubular concrete products, a general section view; in fig. 2 is a schematic drawing of the molded article.

The composite mold is made for central position with the help of a roller-support 10, and the shape is kept from horizontal displacement by the roller-support 11. The end of the product 9 lies on the trolley 12 and with the help of the gripper 13 is fixed on the conveyor belt 14. The drive 15 of the conveyor 14 by means of a cable-block the system 16 drives the carts 12, which from the bottom rus are lifted onto the upper one along the rails 17. Removing the curved articles from concrete mixes The product 9 is thus removed and consists of coaxially arranged bodies rods 12 of the conveyor 14.

The ejector 8 and the carriage conveyor 14 return to the initial feed 1, on parallel faces x 2 of which the forming compartments are mounted in the form of pallets 3 and the longitudinal sides 4 associated with them. The pallet 3 and the cross section of each forming compartment are trapezoidal, with a larger transverse base section of the latter is addressed to the pallet 3.

Composite form works as follows.

At the shaping station, the mold is installed by tires 1 on the drive and support rollers 5 of the centrifuge and their position is fixed on top of the pressure rollers 6, and then the molding sections are filled with concrete mixture, which is distributed, compacted and subjected to heat and moisture treatment. After that, the removal of finished products as follows.

The composite mold for the manufacture of centrifuged products from concrete mixtures is installed with bandages 1 on rollers of the demolishing station, where end caps 7 of the mold are removed and the reinforced concrete product -9 is pushed out along the longitudinal sides 4 which are tilted in

The position, and the multi-sectional shape, by means of the support bands 1, the drive 18 and the support 19 rollers (the drive is conventionally not shown) is rotated by a predetermined angle, and the second, then the third, and so on is removed in a similar way. and and.

20 Clean and lubricate the mold and with the help of a trolley conveyor 14, reinforcement cages are inserted into the mold and transferred to centrifuges.

Invention Formula A composite form for the manufacture of centrifuged concrete products containing coaxially arranged tires, on parallel faces of the inner surface of which the forming compartments of the pallets and associated longitudinal sides are mounted, in order to reduce the labor intensity of the scraper, the pallet and the transverse cross section of each shape the side of the longitudinal axis, which prevents 35 from being made trapezoidal, appendix 9 falls out of shape. The ejectors — the larger base of the cross-sectioned product is supported in the horizon of the latter facing the pallet. the taller position with the help of the roller-support 10, and the form against horizontal displacement is held by the roller-support 11. The end of the product 9 rests on the trolley 12 and is fixed on the conveyor belt 14 by means of the gripper 13. the movement of the carriage 12, which from the lower wheel rises to the upper one along the rails 17. The product 9 thus removed is removed from the carriage 12 of the conveyor 14. The position, and the multisectional shape, by means of the support bands 1, the drive 18 and the support 19 rollers (the drive is conventionally not shown) is rotated at a predetermined angle, and the second and then the third and the second and so are extracted. Clean and lubricate the mold and, using a carriage conveyor 14, reinforcement cages are inserted into the mold and transferred to centrifuges.
