Definitions

  • the present invention relates to a method for producing raw concrete.
  • raw concrete placed in a construction field was prepared in such a manner that cement, ballast and water measured in a batcher plant were put in a rotary drum of a mixer car and the mixture was stirred up by rotating the drum until the mixer car reached the field of construction.
  • An object of the present invention is to provide a method for producing raw concrete wherein sand, ballast and cement each previously measured in a batcher plant are enclosed in a container and a predetermined amount of water is poured into said container in the field of construction and said container is rotated in a mixing drum.
  • FIG. I is a longitudinal, sectional elevation showing a rotating device for a container.
  • FIG. 2 is a lateral elevation thereof.
  • FIGS. 3 and 4 are longitudinal, sectional elevations of the container.
  • FIG. 5 is an enlarged section of a part of the bottom of the container.
  • numeral 1 denotes a pair of side frames opposite to one another, bearings 12 being provided on the upper frames of said side frames 11.
  • Numeral l3 denotes a cylindrical member having a bottom and mounted between the side frames 11, ll, opposite horizontal shafts 14, 14 being provided on said cylindrical member 13 at the outside thereof, said shafts 14, 14 being rotatably journaled in the bearings 12, 12 provided on said side frames.
  • Numeral 15 denotes a worm wheel mounted on one of the shafts l4, 14, said worm wheel 15 being adapted to engage with a worm gear 18.
  • the worm gear 18 is mounted on a shaft 16 rotatably mounted in a bearing 17 fixed to one of the side frames 11. Moreover, the shaft 16 is connected at one end thereof to a reversible motor 19, said motor 19 being mounted on a mount 20 fixed to one of the side frames 11.
  • the cylindrical member 13 having a bottom is rotatable around the shafts l4, 14 as its fulcrum by rotating the motor 19.
  • a drum 21 having a bottom is inserted into the cylindrical member 13.
  • rollers 22 being disposed in the spaces between the cylindrical member 13 and the drum 2] thereby enabling said drum 21 to rotate inside the cylindrical member 13, said rollers 22 being fitted into concavities 23 provided on the inner surfaces of the bottom wall and the side wall.
  • an opening 24 is provided in the center of the bottom wall of the cylindrical member 13, a shaft member 25 being fixed in the center of the underside of the bottom wall of the drum 2] so as to project through the opening 24 of said cylindrical member 12.
  • a sprocket 26 is provided at the lower end of said shaft member 25, a chain 29 being extended between the sprocket 26 and a sprocket 28 of a motor 27 mounted on the exterior wall of the cylindrical member 13.
  • numeral 30 designates a container, said container 30 being produced by such a process that a core material such as glass fiber is wound like cobwebs around a synthetic resin sheet and then lined thereon with resin or that a core material such as glass fiber is wound like cobwebs around a mold and lined thereover with resin and thereafter the mold is disassembled, said container having air-tight property.
  • a belt 31 for hanging the container 30 is provided on the top wall thereof.
  • An opening 32 is provided on the top wall and the bottom wall of the container 30 respectively.
  • a tube 33 is secured at one end thereof to the interior edge of each of the openings 32, the other end thereof being gathered together and closed by a string 34.
  • Numeral 35 denotes a lid of the opening 32, said lid 35 being fixed at one end thereof to the container, the other end thereof being engageable with a buckle 36.
  • FIG. 4 shows the container 30 in which are stored sand A and ballast B both containing water.
  • the cement C is sealed in a water-proof bag D so as to prevent said cement C from absorbing water of the sand or the ballast, said bag D being torn and removed prior to producing raw concrete.
  • the container 30 When raw concrete is required, the container 30 is suspended with the belt 31 thereof by a crane hook, said container 30 being dropped into the drum 2! of the cylindrical member 13 which is sustained vertically. Thereafter, the top wall lid 35 of the container 30 is opened by releasing the buckle 36, a measured amount of water is poured thereinto from the tube 33 by removing the string 34 thereof, air being forced into the container for expansion thereof so that said container 30 may be brought into pressure contact with the inside of the drum 21. Thereafter, the tube 33 is tied by the string 34 and the lid 35 is closed so as to prevent the compressed air from escaping.
  • the motor 27 is switched off, the cylindrical member 13 being adjusted by means of the motor 19 so that said cylindrical member 13 may restore its axially perpendicular position, the air inside the container 30 being released by opening the tube 33 at the side of the top wall, the container 30 being drawn out of the drum 21 by hooking the belt 31 on to a crane hook, said container 30 being conveyed to the spot where the concrete is placed, raw concrete being poured out by opening the lid 35 at the side of the bottom wall of the container 30 and also by opening the tube 33.
  • this invention enables to obtain raw concrete by filling the container with sand, ballast, and cement, each previously measured, said container being placed in the drum, said drum being rotated after a predetermined amount of water is supplied thereinto. Since this invention no longer necessitates mixer cars with which to mix and transport raw concrete, this invention not only prevents the risk of a delay in the delivery of raw concrete owing to traffic congestion, but also precludes inconveniences even at a place difficult of access for a mixer car.
  • this invention enables to place raw concrete at any required place by suspending the container from a crane hook, though hitherto it was necessary to transport raw concrete from a mixer car to elevatable buckets.
  • a method for producing raw concrete wherein a predetermined amount of sand, ballast and cement are stored in a container having an opening at the top and the bottom thereof respectively and having a lid for closing each of the openings, a predetermined amount of water being supplied into the container after said container is inserted into a rotary drum, air being forced into the container so as to bring said container into pressure contact with the drum, the ingredients being mixed inside the container until raw concrete is obtained.
