Description

The invention relates to the construction, namely, devices for compacting the concrete mixture during the construction of monolithic buildings and structures in the sliding and moveable formwork.

A device for compacting a concrete mix is known, which contains a self-propelled trolley with a swivel frame, on which is mounted a manipulator with a deep-moving mobile vibratory compactor [1]. 0

The closest solution known is a device for compacting a concrete mix, containing a self-propelled carriage on which a movable carriage with curved, 5 radially guides and a vibration compactor with a handle moving it mounted are mounted on them [2].

The disadvantage of these devices is the impossibility of their use 70 when using reinforcement cages with different cell sizes.

The aim of the invention is to increase productivity by ensuring the free passage of the vibroplott25 • of the carrier through the reinforcing mesh with distinguishing "! step by step.

This is achieved by the fact that a device for compacting a concrete mixture containing a self-propelled cart, on which

2

the swarm is equipped with a movable carriage with guides curved along the radius and a vibro-compactor placed in them with a handle for moving it, equipped with 5 safety devices,

the vibrating compactor is made sectional, each section of which is in the form of a hollow holder placed in the guides with an in-depth vibrator, and a safety device in the form of rods fixed to the holders and clamps connected to the handle in contact with the rods.

FIG. 1 shows a device for compacting a concrete mix in a unique position, general view; 2 a top view; in fig. 3 - a device for compacting the concrete mix in the working position, general view; in fig

4 - the same, top view.

The device for compacting the concrete mixture contains a self-propelled trolley 1, on which a pneumatic cylinder 2 is fixed, connected with a horizontally movable carriage 3. On the carriage 3 there is a pneumatic cylinder 4, the rod of which is fixed to a platform movable in a vertical plane, connected by means of guides 6 with the carriage 3 On the flat

four

5, a sectional vibro - * / compactor is located, each of the sections of which consists of a hollow guide 7 radially bent along a radius 7 with a hollow holder _g 8 with a dipole 9 which is flexible and radially curved through it hollow holder 8. The holder 8 is fixed to the rod 11, passed through the groove of the hollow guide 7 and in contact. with bevel spring-loaded latch 12. The tabs .12 mounted on the handle of the movement 13, made in the form of a rail, placed in the curved radially of the side rails 14. Self-propelled trolley 1 is set to 15

the rails 15, mounted on the scaffolding 16 formwork along its boards 17 concreted walls 18.

Device for compacting concrete mix works as follows. 20

When the drive of the self-propelled trolley 1 is turned on, the device is brought to the place of compacting the concrete mix. Then pneumatic cylinder 2 horizontally movable carriage 3 is fed to the reinforcement 25 of the frame 19, after which the pneumatic cylinder 4 pad 5 in the guides 6 vertically, setting the vibrating section of the window opposite the windows of the reinforcing cage. After that move the handle 13 in the side rails 14, while the spring-loaded latches 12, interacting with the rods 11, move the holders 8 with the deep vibrators 9 along the hollow guides 7. The deep vibrators 9 go deeper into the concrete mix. Including, if the vibrator encounters an obstacle during its movement, for example, a reinforcement cage rod, then a spring-loaded clamp 12 mounted in the movement handle 13 is pressed out by the rod 11, and the vibrator remains in place, the other vibrators of the sectional vibrator are unobstructed

pass through the mesh of the armo carcass into the compaction zone of the concrete mix. At the end of the compaction, move the handle 13 in the opposite direction, while the fixtures 12, interacting with the rods 11, remove the holders 8 with the immersion vibrators 9 from the sealing zone. Then the self-propelled truck moves along the rails 15 along the wall 17 to the adjacent sealing area. Since on the way of movement of the device there are jacking frames 20 formwork, the carriage 3 in the places of installation of the latter is retracted by the pneumatic cylinder 2 at a distance sufficient for free passage, after which it returns to its original position.

Claims (1)
