SU118744A1 - Device for making supports of grape trellis and similar reinforced products from cement-free concrete - Google Patents

Description

Installations for a shape-free molding of reinforced concrete hollow products using augers are known. The disadvantage of these installations is that they cannot simultaneously produce several products and transporting them at high altitude without formwork is impossible.

The proposed device does not have these disadvantages. Several products are simultaneously manufactured on it, which immediately after molding are guided with one and a half detachable formwork into the steam chamber.

Dryness of the invention lies in the fact that the device intended for the manufacture of supports for grape trellis and similar reinforced products from cementless concrete is made in the form of metallic vertically installed on the vibrating table of a collector form, consisting of several cells equal in height to the product and vertically mounted over the form of augers, intended for dosing and additional compaction of the concrete mix in the form-collector.

The metal form-collector is made detachable from two halves, one of which is hingedly attached to the vibrating table, and the second is made removable and detachable for direction with the product stirred in it to the steaming chamber.

Fig. I shows a schematic diagram of the operation of the device; in fig. 2-device, general view; in fig. 3-form in an inclined position before separating the mold half with the product.

The device for the manufacture of grape trellis supports consists of several units of a mortar mixer 1 installed on a ramp, a silo 2 FOR a solution with twenty screw feeders 3 detachable on

No. 118744-2 -

2 half-shaped collector 4 with 20 cells for making 20 supports at the same time, a vibrating table 5 to which one half of the shaped collector 4 is attached to the hinge, a pioneer crane for unloading the vibrating table and feeding the empty half of the shaped collector and trolley 6, on which a detachable half of the collector shape with supports is laid.

The described device operates as follows. From the mixer / ready-made solution, which consists of 65% sawdust of shell lime, 25% of hydraulic lime and 10% of Tripoli with 23% of water relative to the weight in the toothed, their aggregate, goes into the bunker 2, and with the aid of a screw feeder 3- into a cylindrical detachable form 4 with a length of 2100-2400 mm and a diameter of 100 mm.

The steel form is installed vertically on the vibrating table 5 and is attached to it by the lower part with the help of a flange.

An armature is placed in advance inside the mold. The solution is supplied from the hopper 2 to the furm 4 at the time of vibrating. The solution fills the bottom-to-top gradually and evenly thanks to the dispenser 5.

For better compaction of the upper layer, a screw head 3 is used.

In order to obtain hollow pillars (reinforced pipes), a steel pipe with a diameter of 40 mm is inserted into the inside of the mold into the mold. After vibrating, this tube is removed, leaving a void in the vibrated mass.

When the vibrating is completed, the collector form 4 is tilted (see Fig. 3). At the same time, the right of its half, resting against the protrusion of the lever 7, is shifted upwards relative to the left half of the form-collector and leaves its protrusions 8 out of engagement with the protrusions 9 of the left half.

Using the unwinding cable 10, the right half of the collector form is lowered into a horizontal position on the trolley 6 (or conveyor mite) and sent to the steam chamber. Instead of the removed one, a new empty half of the collector is fed, which is attached to the left half and set to a vertical position to repeat the cycle. the invention

Claims (2)

1. A device for making supports of grape trellis and similar reinforced products from cementless concrete, consisting of a collector mold, a vibrating table and a set of augers, or, moreover, in order to increase productivity, it is made in the form of metal vertically installed on the vibrating table of the collector, consisting of several cells equal in height to the product and vertically mounted above the form of pins intended for dosing and additional compaction of the concrete mix in the form of the collector. 2. The form of the device pop. 1, characterized in that the metal form-collector is made detachable from two halves, one of which is hinged to the vibrating table, and the second is made removable and detachable for direction with the product placed in it to the steaming chamber.
