Abstract

The invention relates to the production of precast concrete, namely, devices for laying rigid concrete mixtures into forms. The purpose of the invention is to improve the quality of products and ease of use. This is achieved by the fact that from the outer side of the sleeves 6 there is a rigidly installed guide 9 with screw clamps, which cover the free ends of the U-shaped brackets through the vertical grooves 12. 5 Il.

The invention relates to a production unit 10 raises or lowers the blade of precast concrete, namely, device-13 along vertical grooves 12 in U-shapes for laying rigid concrete mix brackets 11 and fixed in need of forms, and is an improvement position Then begin by producing an invention according to the author. St. No. 1235736. g to load the paver bunker without the purpose of the invention. The purpose of the invention is to increase the quality of the tonnage mixture and include the drive 8, products, and ease of use.

This begins to reciprocate along horizontal guides 5. As the cone of concrete mix grows, its top gets into the zone of action of the blade and is constantly cut to one side or the other, while the paver's hopper is filled evenly across its width. When reaching the level of concrete in the bunker above the horizontal

The paver consists of a self-propelled portal 1 on which a bunker is mounted

2 with a shutter 3 and a belt feeder 4. 15 axes of the blade; its movement ceases. On the longitudinal walls of the bunker there is a mounted-concrete mixture, if necessary, horizontal guides 5, on which the bushings 6 are movably mounted, eyelets 7 are attached to the bushings 6 ,

connected to the drives 8, and from the outside. . „„

The sides rigidly attached guides 2 products to the mold.

9 with screw clamps 10, which, if necessary, manufacture the product to cover the free ends of the U-shaped

brackets 11 through vertical grooves 12. U-shaped brackets 11 round the walls of the bunker 2 and are connected to the ends of the blade 13 placed inside the bunker. Depending on the stiffness of the concrete mix, the blade along the vert-Beton paver according to the ed. St. No. 1235736, potassium is installed in such a way that, in order to increase the distance from the bottom of the bunker to its product quality and ease of operation, the vertical axis is 5B-tga, where 30 bushings are rigidly fixed to

they are perpendicular to their longitudinal axis by vertical guides with clamps covering the free ends of the U-shaped brackets made with vertical grooves for placing the post-filling to the desired volume. After filling the hopper, the paver runs into the forming post and lays the concrete mixture over the entire width of the moldable

From concrete mixes of other rigidity, the blade position is adjusted to the required height.

Claims (1)

Invention Formula B is the width of the bunker; and - the angle of repose of the cone of the concrete mix. The device works as follows For a given concrete mix empirically, the blade is set to a height , 5Btga. For this, 35 fixes are loosened. The tori 10 raise or lower the blade 13 along the vertical grooves 12 in the U-shaped brackets 11 and fix it in the desired position. Then they begin to load the paver's hopper with a concrete mixture and turn on the drive 8, which This begins to reciprocate along horizontal guides 5. As the cone of concrete mix grows, its top gets into the zone of action of the blade and is constantly cut to one side or the other, while the paver's hopper is filled evenly across its width. When reaching the level of concrete in the bunker above the horizontal the axis of the blade its movement is stopped and the concrete mix, if necessary, the axis of the blade its movement is stopped and the concrete mix, if necessary,   . . „„ products into shape. refill to desired volume. After filling the hopper, the paver runs into the forming post and lays the concrete mixture over the entire width of the moldable If necessary, manufacture of Paver on auth. St. No. 1235736, characterized in that, in order to improve the quality of products and ease of operation, the sleeves are rigidly fixed to From concrete mixes of other rigidity, the blade position is adjusted to the required height.
