DEVICE FOR LAYING REINFORCED CONCRETE ON SURFACES

The invention relates to a device intended in particular for the construction of channels for conveying water or other liquids and for the concreting of roadside embankments. The reinforced concrete is laid both on the bed and along the embankments. With this device it is possible to perform vibration and compaction of the reinforced concrete, including along the inclined surfaces (embankments), in a single operation. The device is formed by a vibrating plate (4) having a length corresponding to the span to be concreted, which plate is situated above the reinforced concrete and rests with its edges on guiding end members (3) pre-arranged on the bed (2) along the channel or roadside embankment, said vibrating plate (4) being provided with a vibrator (5). A rotating roller (6) travels behind the plate (4), both elements being driven by means of laterally arranged steel cables (8) connected to respective winches or winders (10) mounted on a frame or driving carriage. Said driving carriage includes a spindle with a double thread for spanning the space between the guiding end members (3). Another vertical spindle is used to raise the rotating roller (6) and the vibrating plate (4). Dispositivo de vibrado y compactado de hormigón. Cuenta con una placa vibrante (4) de longitud correspondiente al vano a hormigonar, situada sobre el hormigón armado y apoyando sus bordes sobre unos testeros guía (3) previamente dispuestos a lo largo del canal correspondiente a ese vano, contando esta placa vibrante (4) con un vibrador (5). Detrás de la placa (4) circula un rodillo giratorio (6), siendo ambos traccionados mediante cables de acero (8) colaterales y conectados a sendos cabrestantes o enrolladores (10) montados en un bastidor, o carro motriz.
