  • Patent number: 11518064
    Abstract: A deflection impedance device is provided for a stripper head plate of a concrete product machine mold assembly. The device may comprise a spacer having an axial thickness generally equal to a desired spacing between an upper surface of a stripper head plate of a mold assembly stripper head, and a lower surface of a mold head adapter plate of a concrete product machine. A magnetic element may be used to retain the spacer on the stripper head plate upper surface where it will brace the stripper head plate against the mold head adapter plate to limit or prevent upward bowing that might otherwise result from forces imparted by concrete product being formed within the mold assembly.

  • Patent number: 8968623
    Abstract: A method for demolding concrete blocks which are cast in a resilient mold supported in a rigid frame, the mold having a top surface and at least one cavity with an opening on the top surface, which cavity holds a cured cast concrete block. The mold has two opposing edges. The demolded blocks are stacked on a collection surface. A support is positioned over the cavity and the mold, the support and the frame are inverted and positioned in demolding apparatus. After two opposing edges of the mold are engaged by the demolding apparatus, the support is withdrawn to allow the mold to sag. The blocks may release from the mold and fall onto the collection surface. If any blocks remain in the mold, a plunger mechanism is pushed against the sagging mold to release the blocks. Guide members may facilitate positioning the blocks on the collection surface.

  • Patent number: 8894897
    Abstract: The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.

    Abstract: A portable single station method and apparatus for compressing a quantity of freshly dug soil into building blocks by an enclosed system which provides a linear process for receiving and compressing the quantity of soil and for ejecting the formed, compressed building blocks. The system includes a stationary chamber equipped with an internal adjustable cavity in which the desired block is formed and a pair of opposing pressure heads capable of moving toward and away from each other in unison or independently to receive, compress, and eject the building blocks.

  • Publication number: 20020047223
    Abstract: A method and apparatus for efficiently forming individual building units is provided, generally includes providing a plurality of molds, each capable of simultaneously forming a plurality of building units. Batches of cementitious slurry are individually mixed in order to control the density of each building unit formed. The ingredients are individually measured and combined into the mixing device. The cementitious slurry is then conveyed or transported and poured into one of the molds. The method provides the ability to control the amount of cementitious slurry in each batch in order to control to the extent possible the quantity of cementitious slurry poured into each mold and the ability to precisely control the dimensions of each building unit produced.

  • Patent number: 6355191
    Abstract: A method and apparatus for preparing single layer tiles or slabs from a mixture of a granulated stone material having a selected particle size, and from a slurry formed by cement, a quantity of between 0.25 and 0.36 parts by weight of water relative to the weight of cement, and a plasticizer for cementitious slurries, in which the quantity of slurry added is slightly in excess of the quantity corresponding to the void fraction of the granulated material, in forming mould, containing a layer of predetermined thickness of the mixture, to be subjected to a first very short deaeration step under the effect of a very high vacuum and to a subsequent vibration step under a lower vacuum, after which the mould goes on to seeing and hardness steps.

  • Patent number: 6322742
    Abstract: A method of preparing stackable block structures from raw concrete mixes and block structures prepared in accordance with the method, wherein the process utilizes a mold box configured to form the block on its side surface. The mold box is arranged to travel along the surface of a moving conveyor belt, with the box having an open top, an open bottom, and lateral side panels supported on the conveyor belt surface, and with the panels having core bar receiving openings formed therein. The core bars are introduced and removed from the mold box along an axis which is parallel to the surface of the core bars and to the motion axis of the conveyor belt, and with the core bars configuring one of the two opposed side surfaces of the stackable block. A reciprocating top shoe arranged for reciprocatory up and down motion engages and configures the top surface of the raw concrete mix held within the walls of the mold box.

  • Patent number: 6298632
    Abstract: A modular building unit (1-6, 1A) including a building block (10, 10A) having lower and upper faces (9, 9A, 11, 11A), side faces (12, 12A, 13, 13A) and end faces (14, 14A). At least the lower and upper faces are provided with mounting strips (21-24, 53A, 54A) interfit with mating mounting strips (21-24, 53A, 54A) on similar adjacent modular building units (1-6, 1A) to join the adjoining building block units (1-6, 1A) in predetermined dimensionally accurate relationships. A method of securing the mounting strips (21-24, 53A, 54A) to the building block or brick (10, 10A) and the method of interlocking and securing adjacent modular building units (1-6, 1A) to each other are disclosed. A preferred embodiment of mounting strips (53A, 54A) is shown in FIGS. 8-10. A mold (203) is shown in FIG. 12 for the preferred method of forming a building block or brick (200).

  • Patent number: 6182416
    Abstract: A method for fabricating a tilt-up concrete wall panel atop a concrete slab includes reinforcing a form atop the concrete slab with at least one stick-on block to avoid making nail or screw holes in the concrete slab. The block is removably secured to the slab adhesively. One common form block includes an injection molded body of material with a stick-on base portion and two upstanding flange portions that define a channel adapted to receive a common form member. A preferred edge form block is triangularly shaped.

  • Patent number: 6177039
    Abstract: A mold box is flexibly mounted to a product forming machine having upper and lower vertically displaceable beams. A feed drawer dispenses concrete material into the mold box while a vibration system vertically vibrates the mold box while dampening horizontal vibration. The vibration system is driven by a single drive shaft that actuates first and second vibrator rods while at the same rotating a counter-weight in a counter-rotating direction. A set of alignment brackets lock the mold box into a predetermined aligned relationship while being mounted in the product forming machine. The bottom side of each mold box is mounted to the product forming machine in the same relative position to reduce machine readjustments. A set of telescoping legs hold the feed drawer assembly variable distances above the mold box. A unitized pallet feeder quickly moves pallets one at a time from an “on-deck” position to a “receiving” position underneath the mold box.
