Description

The invention relates to the production of precast concrete and reinforced concrete.

A device for surface compaction of building mixtures is known, which contains a self-propelled portal with a working body suspended from it by means of a loading frame with an oscillating agent [1].

The closest in technical essence to the invention is a device ¹⁰ , for. compaction of building mixtures, containing a working body with rollers fixed to its ends and an oscillation pathogen [21.

The disadvantages of the known devices are the low quality of products obtained with their use and low productivity due to multiple. passageways.

The purpose of the invention is to improve the quality (and the intensification of the processes of compaction — I nii.

This goal is achieved by the fact that the device for compaction of building G mixtures, containing a working body with rollers fixed at its ends and an excitation agent, is equipped with an additional excitation agent and upper and lower connecting frames with racks located one above the other, and the working element is made of contacting the side walls and movable relative to one another sections, the even and odd sections of the working body are connected respectively to the racks of the lower and upper connecting frames, on each of which a vibration exciter is mounted.

In addition, the vertical side 'walls of the sections of the working body are located in plan at an acute angle relative to the longitudinal axis.

In FIG. 1 schematically shows the proposed device for sealing construction mixtures, general view :, in FIG. 2 is a section AA in FIG. 1.

A device for compaction of building mixtures consists of a working body, divided into sections 1, main 2 and additional 3 pathogens [vibrations] mounted on the upper 4 and lower 5 5 connecting frames. .Sections; 1 are movably interconnected by means of, for example, a finger 6 in one section, I placed in the groove of another section. Stands, ki 7 of the upper frame 4 are rigidly connected to it. The racks 8 of the upper frame 5 are connected with sections 1, for example, springs 9, while the racks 8 can be made in the form of impactors, under which the anvils are placed 10. The racks 7 of the upper frame 4 are made in the form of guides of the lower frame 5, the vertical side walls of the sections 1 located in plan at an acute angle to the longitudinal axis of the working body, to the ends of which are attached by means of parallelogram suspensions 11 of the roller 12, and the racks 7 of the upper frame 4 are connected with the odd sections 1, and the rack 8 of the lower frame 5 is connected with even sections 1 & 1 of the working body.

A device for compaction, building mixtures (as follows.,

The device is installed over the surface of a concrete or other mixture, then the adjusting screw (not shown conventionally) lower sections 1 until they contact the surface of the laid construction mixture, include the main and additional pathogens 2 and 3 of the oscillations, which act on sections 1 with different amplitudes and ³⁵ different frequencies, which ensures high-quality study of the compacted mixture. To ensure overlapping of the sealing zones during the movement of the device, the lateral vertical walls. Ki sections 1 are installed in plan at an acute angle to the longitudinal. It is possible to combine the vibrational mode of the seal with the shockproof one, for which there are anvils 10 located under the uprights 8, which perform the function of shockers.

Using the proposed device for compaction of building mixtures will improve the quality of the molded products and intensify the reduction processes.

FIELD OF THE INVENTION The invention relates to the precast concrete products of precast concrete and reinforced concrete. A device for surface compaction of building mixtures is known, which contains a self-propelled portal with a working body suspended from it by means of a loading frame with an oscillation pathogen 1. The device closest to the technical essence of the invention is the device; compaction of building mixes, which contains a working body with rollers fixed at its ends and a C 2 oscillator. The disadvantages of the known devices are the low quality of the products obtained with their use and low productivity due to multiple passes. The purpose of the invention is to improve the quality and intensify the processes of compaction. This goal is achieved by the fact that the device for compacting building mixtures, which contains a working body with rollers fixed at its ends and a vibration exciter, is equipped with an additional vibration exciter and located one above the other upper and lower connecting frames with racks, and the working body is made of a composite of contacting side walls and moving one relative to the other sections, even and odd sections are working its body associated respectively with the uprights and bottom erhney connection frames, each of which is mounted exciter. In addition, the vertical side walls of the sections of the working body are located in the plan at an acute angle relative to the longitudinal axis. FIG. 1 schematically depicts a depot for compacting building mixtures, a general view., FIG. 2, section A-A in FIG. I. A device for compacting building mixes consists of a working body, divided into sections 1, main 2 and an additional 3 exciters, mounted on the upper 4 and lower 5 connecting frames. ; Section; 1 is connected between the co (5th through, for example, 7 fingers 6 on one section, I placed in the groove of another section. The uprights 7 of the upper frame 4 are rigidly connected to it. The uprights 8 of the upper frame 5 are connected to sections 1, for example , ui :) with dinners 9, with the racks 8 can be made in the form of strikers under which the anvils are placed. The uprights 7 of the upper frame 4 are designed as guides of the lower frame 5, the vertical side walls of the sections 1 are in plan at an acute angle to the longitudinal axis of the working body, to the ends of which are attached by means of a pair The llogram pendants 11 are rollers 12, the upper frame 4 pillars 7 are connected to odd sections 1, and lower frame 5 pillars 8 are connected to even sections I of the operating element. A device for compaction of building-pipe mixes (as follows. The device is installed above the surface of a concrete or other mixture, then an adjustment screw (conventionally not shown) is lowered into section 1 until contact with the surface of the laid building mixture includes which act on sections 1 with different AP litudes and different frequencies, which ensures high quality development of the mixture to be compacted. The lateral walls of the sections 1 are installed in the plan at an acute angle to the longitudinal axis. A combination of vibratory sealing and vibro-impacting is possible, for which there are anvils 10 placed under the struts 8 that perform the function of impactors. quality of molded products and to intensify the processes of consolidation. Claims of the invention 1. A device for compacting building mixtures, containing a working body with fixed on its ends are rollers and a pathogen of vibrations, characterized in that, in order to increase the quality and. Intensification of the compaction process, it is equipped with an additional oscillation pathogen and connecting frames with racks one above the other, and the working body is made up of a composite of contacting side walls and moving one relative to the other sections and the upper connecting frames, on each of which the oscillation pathogen is mounted. 2.
