(54) DEVICE FOR CONCRETE BONDING

MIXTURES

one

The invention relates to the construction, in particular, to devices for the construction of annular shafts made of reinforced concrete and other densely reinforced structures.

A device for compacting concrete mixtures in the manufacture of reinforced concrete products is known, which comprises a winch mounted on a self-propelled platform and a package of immersion vibrators associated with it, which are placed on the lifting-lowering beam 1.

Closest to the present invention is a device for compacting concrete mixtures, comprising a winch mounted on a self-propelled platform and a package of deep vibrators 2 associated with it.

However, the known devices have an insufficiently effective process of compacting concrete mixes, especially in heavy-duty reinforced structures, since they do not provide the convenience of delivering a package of immersion vibrators to the place of concreting — vertical passages in the reinforcement cage.

The purpose of the invention is to intensify the processes of compaction of concrete mixtures in the mine armo carcasses.

This goal is achieved by the fact that in the device for compacting concrete mixes, which contain a winch mounted on a self-propelled platform and a package of vibrators connected with it, the platform is provided with vertical guides forming the spatial frame and the package of vibrators in contact with the last fairing, cross section which corresponds to the configuration of the vertex, Q is the pit passage in the cells of the reinforced cage

15 A device for compacting concrete mixtures consists of a self-propelled platform 1 mounted on rollers 2 supported on a circular rail 3. Platform I is made centrally rotating, for which it is equipped with an axis 4 and an electric drive 5. The package of vibrators 6 is equipped with a fairing 7, the cross section of which corresponds to the configuration of vertical passages in armored frame cells. Winch 8 mounted on platform 1, vibrator pack 6

and the space frame 9, made in the form of vertical guides. A cable 10 is connected to the package of vibrates)) () in 6, one circuit of which is passed through block 11 and is equipped with a tensioning device 12.

The vibration compacting device has a control panel 13 mounted on the service platform 14.

On the package of vibrators 6

A co-disconnecting shut-off driver 15 is placed, the actuator Lion is supplied to the magnetic bed 8 (not shown), and a pressure pin 16, mechanically connected to the limit switch 15, is installed at the bottom end of the fairing 7.

A device for compacting concrete mixes works as follows.

The operator becomes on the platform 14 and from the control panel 13 by switching on the electric drive 5 moves the platform 1 until it coincides in plan of the space frame 9 with the vertical cable and the reinforcement cage. At the same time, the platform rotates I) i with respect to axis 4, moving on a roller x 2 along a circular rail 3. A package of vibrators 6 is pulled down by a winch 8 along the passage of the reinforcement cage to the place of compaction of the mixture. Obtekat; 1 7 provides the movement of the vibropackage in the passage of the cell, reinforced frame without touching the armature. Following the package of vibrators 6, a cable 10 is fed through the hollow axis 4 and block 11. A mobile device 12 provides movement of the cable 10 without sagging or slipping. When the package of vibrators 6 reaches a predetermined depth, the winch 8 is stopped and the vibrators 6 are turned on. Further, their immersion into the concrete mixture is controlled with the help of the end switch 15 and the abutment 16 associated with it. lifting the package of vibrators 6, which continue to work while they are being removed from the concrete mix. Then the package of vibrators 6 is raised to the initial position and the platform is moved to another cell.

The proposed device makes it possible to significantly intensify the process of compacting concrete masses in mine reinforced frames.
