The machine is placed in front of said emitter and the laser receivers 101 are adjusted vertically on the struts 5 until they are focused on the emitter and are fixed there by means of the knobs 51, so that the processor 10 receives an electrical signal that is applied to the electro-hydraulic means 9 that place the extension plates 6 and 7 and also the vibrating strip 8 at the level level. The adjustment of the lateral extensions is then carried out by manual operation of the hydraulic means 14, to work with variable pitch widths, for example, between approximately 2 and 4 meters, being able to avoid lateral obstacles within these dimensions.
Con el desplazamiento de trabajo de la máquina sobre el hormigón ya echado, la primera plancha 6 realiza un primer extendido grueso que es rematado por el posterior paso de la plancha de extendido fino 7. Después, la regleta vibradora 8 y la plancha de extendido grueso 6, mediante accionamiento hidráulico manual de sus medios motrices 12 se encargan de realizar el vibrado de la masa de hormigón ya nivelada.With the machine working displacement on the concrete already cast, the first plate 6 performs a first thick spreader that is finished off by the subsequent passage of the thin spreading plate 7. Then, the vibrating strip 8 and the thick spreading plate 6, by manual hydraulic actuation of its driving means 12 are in charge of vibrating the dough of concrete already leveled.
Como será fácilmente comprendido por los expertos, para realizar la citada secuencia operativa las planchas de extendido 6, 7 y la regleta de vibrado 8 tienen que estar mutuamente desplazadas en sentido vertical, estando más alta la primera de ellas. Se estima como distancia vertical apropiada, por ejemplo, 2 cm, en función del tamaño de las partículas gruesas que puede incorporar la masa de hormigó .As will be easily understood by the experts, in order to carry out the aforementioned operational sequence the extension plates 6, 7 and the vibrating strip 8 must be mutually displaced vertically, the first one being higher. It is estimated as an appropriate vertical distance, for example, 2 cm, depending on the size of the coarse particles that the concrete mass can incorporate.
Suficientemente que se ha descrito la invención, solamente resta señalar que las realizaciones derivadas de cambios de forma, dimensiones y similares, así como las resultantes de una aplicación de rutina de lo anteriormente revelado, deben considerarse incluidas en el ámbito de la invención, de manera que la misma tan solo estará limitada por el alcance de las siguientes reivindicaciones. Sufficiently that the invention has been described, it only remains to be noted that the embodiments derived from changes in shape, dimensions and the like, as well as those resulting from a routine application of the above disclosed, should be considered included in the scope of the invention, so that it will only be limited by the scope of the following claims.
