SU1484733A1 - Device for compacting concrete mix in a form - Google Patents

Description

The invention relates to the production of precast concrete and reinforced concrete and allows to intensify the processes of compaction and adjust to the optimum mode of operation. This is achieved due to the fact that

a device for compacting concrete mixtures in a form provided with horizontal horizontal oscillations parallel to the main exciter and pivoting L-shaped levers 11, Fixed frame 2, movable and counterbalancing ramies are equipped with axles and upper lower contact elements in contact with each other. -designed levers 11, the lower shoulders of which are pivotally connected to the longitudinal rods 13 of the main and additional pathogens horizontally directed to oscillations. The upper shoulders of the L-shaped levers 11 are connected by means of rods with corner links of the vibroblocks 1, mounted on moving frames, 1 hp, f-ly,

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

The purpose of the invention is to intensify the processes of compaction and tuning to the optimal mode of operation,

In Fig.1 schematically shows a device for compacting concrete mixtures in the form, a general view; FIG on ^A, 2 - same, side view; on fig.Z the same, top view; FIG. 4 shows the node I in FIG. figure 5 - node II in Fig, 2; fig, b - section aa on fi g, 4.

A device for compacting concrete mixes in the form consists of vibratory blocks 1 mounted on a fixed frame 2 by means of elastic supports 3, with anti-theft locks 4. Each vibroblock 1 consists of a movable 5 and a counterbalancing 6 frames connected by elastic elements 7, with a movable 5 and balancing 6 ramies contact one another with the help of the upper and lower elements 8 fixed on them, respectively. The movable 5 frame of each vibroblock 1 is connected to the upper arms of the rotary links 10 by means of rods 9 with elastic links 10 s levers II, are installed on trunnions 12, fixed to the fixed frame 2 and the bottom pivotally connected arms with longitudinal rods 13, the ends of which are fixed the main 14 and secondary 15 exciters horizontally directed vibrations. On the lower arms of the L-shaped levers 11 and in the longitudinal rods 13, additional holes 16 and 17 are formed to accommodate, respectively, the axes 18 of the hinges, the holes 16 and 17 being located at the same distance one ςτ of the other, and fixed on the fixed frame 2 the clips 19 and the trunnion 20, providing a permutation of the vibroblocks at a specified distance from one another,

Device for compacting concrete mixtures in the form works as follows.

After installing form 21 on the vibroblocks 1 and filling it with a concrete mixture, the main 14 and an additional 15 longitudinal oscillation pathogens are inserted, thanks to which the rods 13 begin to perform reciprocating postunitor displacements, thereby forcing the L-shaped levers 11 to perform pendulum oscillations and transform the longitudinal horizontal displacements of the longitudinal the rods 13 in the vertical reciprocating movement of the rod 9 and the movable 5 frames of the vibroblocks 1, which are impacted by the buffer elements 8 with the balancing 6 frames,

In the case of measuring the dimensions of the molded product 21 and not coinciding its center of mass with the geometric center, the installation step of the vibroblocks 1 on the fixed frame 2 is modified using additional pins 20 and additional anti-theft locks 19,
