Description

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

According to the main author. St. No. 654410 known vibro platform containing installed on the base using a double-circuit cable-stayed suspension in the form of upper and lower cables with guides and support blocks and a tensioning device movable rake Cl j.

The disadvantages of this vibratory platform is the long duration of the molding and the low degree of compaction of the concrete mixture.

The purpose of the invention is to reduce the molding time and increase the degree of compaction due to the impact on the concrete mixture by shock pulses.

This goal is achieved by the fact that the vibration platform containing installed on the base with a double-circuit cable-stayed suspension in the form of upper and lower cables with guides and support blocks and a tensioning device movable frame is equipped with elastic elements fixed to the base symmetrically to the longitudinal axis of the cable-stayed suspension, which are additionally supported movable frame.

In FIG. 1 schematically shows a vibration platform, general view; in FIG. 2, section AA in FIG. 1.

the vibrating platform consists of a movable frame 1 with a vibrator 2 and movable blocks 3 Moving blocks 3 are based on the lower cable loop

Aa '

4, which lies on the fixed blocks 5, mounted on the base 6. From above, the movable blocks 3 are pressed by the upper cable loop 7, which allows the tension 5 to change during operation of the tensioning device 8.

On the basis of 3 symmetrically the longitudinal axis of the cable-stayed suspension (upper 7 and lower 4 cables), elastic elements 9 are elongated 10 10, on which movable frame 1 is additionally supported,

The vibrating platform works as follows.

Before installing the mold (not shown) on the movable frame 1, the tension in the upper cable loop 7 is relaxed, after which the mold is mounted on the movable frame 1, while the 2Q weight of the latter is balanced by the elastic elements 9.

Then a vibrator 2 is turned on, the vibrations of which set the movable frame 1 in motion, which then strikes 25 periodically about the lower cable loop 4, and the concrete mix ““ is fed into the mold. After filling the concrete mixture of the form, the upper cable loop 7 is pulled and the concrete mixture is densified by texotropic dilution. After completing the compaction of the product, turn off the vibrator 2 and transfer the product to heat treatment.

Using the proposed vibratory platform will reduce the molding time and increase the degree of compaction of products from concrete mixtures.
