(54) DEVICE FOR SUBMISSION OF CONCRETE MASS WHEN FORMING VOLUME ELEMENTS

one

The invention relates to devices for forming bulk elements from concrete mixtures in installations for volumetric molding.

A device for filling an installation with a concrete mass is known, which contains a nozzle arranged for vertical movement inside a silo, which can be displaced in a vertical direction by means of a power cylinder 1.

It is also known a device for supplying concrete mass during the molding of bulk elements, containing a movable frame and an outer and an inner bunker mounted on it, forming in the lower part the contours of the bulk element, interconnected by means of joints and drawn with the possibility of vertical movement relative to each other 2.

A disadvantage of the known device is the location of the hinge joints, slots with slots and t in the zone that is in direct contact with the concrete mix, and, therefore, in the process they will be clogged with concrete and will fail.

Another disadvantage is the presence on the inner contour of the bunker of a flat horizontal platform, which serves to fasten the hinges. Concrete mix from this site will have to be removed manually.

5 The purpose of the invention is to increase the productivity and reliability of the device and improve working conditions.

This goal is achieved by the fact that the device for feeding concrete mass when

10 forming volumetric elements containing an outer shape with a vibrating core and a dispensing hopper with a distribution cone capable of vertical movement inside the hopper are provided with guides that allow 15 limited movement of the distribution cone closing the dispensing slot during the loading of the hopper with the mass in the transport position and opening it in

20 moment of laying on the vibrating core of the form. FIG. 1 shows the device at the time of laying the concrete mix in the form after installing it on the vibrating core with a crane, cross section; in fig. 2 - distributing hopper loaded with concrete mix

transport position, cross section; in fig. 3 - the device, view in plan.

The device can provide the molding of polygonal products (Fig. 3a) and curvilinear sections (Fig. 36).

The unit for volumetric molding consists of an outer mold 1, a vibrating core 2, a device for feeding concrete mix installed on the vibrating core 2 and consisting of an outer bunker 3, a distribution cone 4 installed inside the bunker 3 in guides 5, which limit the deviation of the distribution cone 4 from verticals and defining the size of the slit 6 for loading concrete 7.

The device using the lifting beam 8 is visited on the hook of the lifting mechanism.

The device works as follows.

The outer bunker 3 and the distribution cone 4, when not in use, form a cavity closed into the bottom, into which the concrete mass 7 is loaded. After loading, the hopper 3 with the help of the crosspiece 8 is fed by a crane to the vibrating core 2.

During installation, the distribution cone 4 sits on the conical part of the vibrating heart 2, and the outer bunker 3 is lowered by means of gravity in the guides 5 until it stops.

When the outer hopper 3 is lowered, a slot 6 appears in the lower part between it and the distribution cone 4, through which, when the vibrators are turned on, the concrete mass 7 flows out into the form 8.

the formation cavity between the form 1 and the vibrocord 2.

Due to the introduction of fixed guides instead of the hinge elements, blocking them with concrete and, as a result, stopping the work for cleaning the device is eliminated.

This will increase productivity and improve working conditions.
