Definitions

  • the present invention relates to an installation for the manufacture of concrete finished parts and plate slabs with a flat and horizontal form track or form channel supported on vibrating metal rails, which is provided on its bottom side with longitudinal bearers arranged parallelly to its longitudinal axis and resting on the vibrating metal rails, and with a vibratory slide carriage displaceably arranged in the longitudinal direction below the form channel.
  • the installation according to the present invention finds application for the manufacture of finished parts from concrete as are used in residential and industrial constructions.
  • the form track or channel of the installation serves as form base surface on which are mounted in a conventional manner the necessary lateral form walls.
  • the forms are filled with concrete whereby the condensing of the filled-in concrete takes place by a vibrating slide carriage adapted to be displaced by an electric motor.
  • the vibrating slide carriage engages at the form track or channel and sets the same into vertical vibrations of small amplitude; in order to make this possible, the form track or channel is supported on vibrating metal rails.
  • Such types of production tracks or channels are known per se and consist essentially of a long and narrow form track or channel reinforced by cross bearers.
  • the cross bearers are thereby placed on longitudinal bearers which support the manufacturing track or channel along its longitudinal edges.
  • the longitudinal bearers rest on vibratory metal elements.
  • Two further profile irons disposed closely adjacent one another are arranged between the outwardly disposed longitudinal bearers below the form track in proximity and parallel to the longitudinal axis thereof; the two further profile irons are secured at the cross bearers.
  • the vibrating slide carriage is displaceably arranged between these profile irons so that depending on requirement it can be moved below the respective concrete zone or zone to be filled with concrete.
  • the form track or channel is, as viewed in cross section, supported at the outer edges thereof by means of the vibrating metal rails, and the excitation of the concrete zone takes place by the vibrating slide carriage in two points located near the center of the form track.
  • the main object ofthe present invention resides in eliminating the aforementioned disadvantages of the known manufacturing tracks. It has been discovered that this is attainable by a suitable change of the location both of the support points as well as of the engaging points for the excitation of the form track.
  • the present invention solves the underlying problems in that the longitudinal bearers are arranged at a distance from the longitudinal edges of the form track corresponding to at least one-fifth of the width of the form track, and in that the vibrating slide carriage engages directly at the longitudinal bearers.
  • the vibrating slide carriage is provided at both sides with two jawlike endpieces resting on the inner surface of the lower flange of the longitudinal bearers consisting of wideand parallel-flanged double-T-irons.
  • the width of the gap between the bottom side of the upper flange and the upper edge ofthe endpiece is so selected that the remaining air gap is smaller than the amplitude produced by the external vibrators in the vibrating slide carriage so that a completely satisfactory transmission of vertical vibrations to the form track takes place.
  • the use of double-T-irons with wide and parallel flanges precludes (in contrast to the ordinary double-T or U- steel members with inclined inner-flange top-surfaces) a wedging or jamming of the slide carriage at the longitudinal bearers.
  • the form track or channel consists of form tables arranged one behind the other in the longitudinal direction and pivotal upwardly about a pivot axis extending parallelly to the longitudinal axis.
  • the form tables constructed so as to pivot nearly up to the vertical position permit the manufacture of concrete plates which have to be removed standing vertically.
  • the upward pivoting is realized by means ofa crane engaging at a longitudinal edge.
  • overload traverses or crossbeams displaceable above the form track in the longitudinal direction thereof and carrying rotating spindles while upright struts or posts are arranged at the ends of the traverses which includes base portions resting on the form track and skidlike guides surrounding the longitudinal edges of the form track.
  • the overload crossbeams or traverses serve in conjunction with the rotating spindles for clamping-on the side forms of the form track or channel.
  • the overload traverses can be displaced out of the operating area.
  • the foot portions of the struts carry pairs of rollers running one behind the other.
  • the rollers consist of an elastic synthetic resinous material of any known type.
  • the use of a synthetic resinous material dispenses with a lubrication of the roller bearings; a sufficiently elastic synthetic resinous material effects a self-cleaning of the running surfaces of the rollers from concrete during displacement of the cross beams or traverses.
  • the spanning traverses or cross beams may be formed of two U-shaped irons with the backs thereof disposed opposite one another, and the rotating spindles are displaceable between the U-shaped irons and on pairs of guide rails located above and below the U-shaped irons.
  • Each traverse carries several rotating spindles which can be displaced in the transverse direction to the form track corresponding to the necessary position of the side forms.
  • the construction of the overstress cross beams or traverses from two U-shaped irons and the use of the guide rails at the rotating spindles permits a simple cleaning of these parts.
  • the single FIGURE is a front elevational view of one embodiment of an installation for the production of finished parts made from concrete in accordance with the present invention.
  • reference numeral 1 designates two vibrating metal rails which are secured on a subframe illustrated only schematically and essentially of U-shaped construction in cross section.
  • Upwardly directed support arms 2 extend from one side ofthe subframe.
  • a flat and horizontal form track or form channel 3 rests on the vibrating metal rails 1 which consists of individual form tables 4 and 4' of any suitable number arranged one behind the other in the longitudinal direction and pivotal in the upward direction.
  • each form table 4 and 4 is formed by a thin form layer 5 made from steel, wood or synthetic resinous material reinforced with glass fibers, which rests on cross bearers 6 having a double-T profile. Lateral edge angles at the projecting form.layer 5 form the longitudinal edges 7 of the form track. Longitudinal bearers 8 are secured to the bottom side of the form tables 4 and 4' which rest on the upper surface of the vibrating metal rails 1.
  • the longitudinal bearers 8 consist of double-T-irons with wide and parallel flanges; the distance of each longitudinal bearer 8 from the longitudinal edge 7 of the form track 3 amounts to about one-fifth ofthe width of the form track 3.
  • a vibrating slide carriage 9 is arranged between the longitudinal bearers 8 which is displaceable in the longitudinal direction of the form track 33
  • the vibrating slide carriage 9 which is of conventional construction can be pulled into the desired concrete zone by the use of an electric motor (not shown) having an adjustable rotational speed and by means ofa cable 10.
  • the vibrating slide carriage 9 is constructed of tublike shape.
  • Two external vibrators 11 of the electric or selectively of the compressed-air type of any known, conventional construction which operate in the same direction, are disposed on the inside of the slide carriage 9.
  • Two jawlike endpieces 12 and 13 are provided on the vibrating slide carriage 9 at the two sides facing the longitudinal bearers 8, by means of which the vibrating slide carriage 9 rests on the inner surface of the lower flange 14 of the longitudinal bearer 8.
  • U-shaped spanning traverses or cross beams 19 intended to absorb overloads are disposed above the form track 3 which are displaceable in the longitudinal direction thereof.
  • a crossbeam or traverse 19 consists of two parallel U-shaped irons 20 disposed back to back opposite one another; at the ends of the cross beams 19 are disposed vertically downwardly extending struts or braces 21 which include at the inner side thereof U- shaped base portions, in which are arranged a pair of rollers 23 consisting of elastic synthetic resinous material of any known appropriate type.
  • the rollers 23 run along the top side of the longitudinal edges 7. Below the lateral rim angles the struts 21 are providedopposite the rollers 23with skidlike guide portions 24 which surround the longitudinal edges 7 of the form track from below.
  • the present invention proposes a production track or channel adapted to be manufactured in a price-favorable manner, by means of which can be produced concrete finished parts that are condensed homogeneously and have uniform thickness.
  • a production track or channel adapted to be manufactured in a price-favorable manner, by means of which can be produced concrete finished parts that are condensed homogeneously and have uniform thickness.
  • form track means consists of a plurality of form tables arranged one behind theother in the longitudinal direction and adapted to be pivoted up about a pivot axis parallel to the longitudinal direction.
  • rollers consist of an elastic synthetic resinous material.
  • crossbeam means are formed of two U-shaped section members disposed opposite one another with the backs thereof, the rotating spindle means being displaceable between the U shaped section members on pairs of guide rails disposed above and below the U-shaped section members.
  • the form track means consists of a plurality of form tables arranged one behind the other in the longitudinal direction and adapted to be pivoted up about a pivot axis parallel to the longitudinal section.
