The vibro -concrete products used in the production of small reinforced concrete products have the following main parts: the lower frame to which four springs and an electric motor with a capacity of 0, 70 ket are attached and a speed number of 2500 per min., upper working frame resting on springs. Eccentrics are suspended to the working frame from below, leading the upper frame to the oscillatory movement, and through it formwork forms filled with concrete. In front of the vibration stream and behind it, tables equipped in the upper part of the rollers (roller tables) are installed in the same line, the height of which is the same with the height of the vibro -stroke. The working frame of the vibration stroke is equipped with rollers on ball bearings that facilitate the supply of formwork shapes to the vibrostol and rolling off the omitted products. For lifting and lowering the vibro -stroke, swinging supports, connecting rod, electromagnet are used. For vibration of concrete heavier reinforced concrete products (continuous plates and beams of ceilings, flooring, etc.) Vibro-floodplains of the SSSM-544 of a stationary type are used, mounted in the floor of the workshop of large heavy structures. The upper frame on the top has a continuous plank flooring, on which the corners of a narrow rut of 750 mm are located to the possibility of rolling onto the site of the shelf-layer with formwork forms filled with concrete. The load from the upper frame to the lower is transmitted through cylindrical springs. When the helm of the eccentricity of the debans changes, the centrifugal force within 300-1000 kg and the amplitude of the frame oscillation from 0, 5 to 3 mm change. Vibro -seizure weight 670 kg.
Vibration with vibrovouses, unlike previously considered methods, is made not from the outside of the product, but from the inside of it. In this case, the waves are transmitted to concrete from vibrovatok placed in the body of a concrete product. This vibration method is used for forming hollow beams and large blocks.
When concreting large concrete blocks, vibrovouses are located at a certain distance from each other. The liner of the liners is the upper beam with electric motors located on it. Such a system of liners and beams is called vibration.
