  • Patent number: 10167638
    Abstract: The invention is a mixed stucco block of gypsum blocks. Due to using a layer of compacted polystyrene in its center, it is much lighter than regular gypsum blocks. In addition, its heat transfer coefficient is less than solid stucco panels. In addition, due to applying some smithereens in it along with support system and innovative Rabyts, mechanical connection of cement mortar is provided for it. Therefore it is possible to use this block in wet places including in bathroom, WC, and as the side wall of the façade.

  • Patent number: 9221190
    Abstract: An engineered stone production plant includes a vacuum vibration press (“VVP”) suspended above the ground, so that a conveyor belt and/or returning empty trays or molds from a curing oven to a mixing station can pass beneath the VVP. Rigid, self-supporting trays or molds can convey slabs through the plant on rollers, which allow independent horizontal movement of the slabs during spreading and coloring/veining of the slab mixture. Embodiments include air levitation for transporting slabs into and out of the VVP. The curing oven can be air-heated. The pressing plate can be sealed with the tray or mold by walls that extend downwardly from the press plate over a flexible covering sheet, by a gasket surrounding the pressing plate, or by an angle strip surrounding the slab mixture. In embodiments, the slab size can be changed by exchanging elastomeric mold walls, or by exchanging molds and pressing platens.

    Abstract: A method of manufacturing engineered stone slabs provides slabs that are equal or superior in appearance and physical properties to slabs manufactured using a conventional Breton press, while weighing less, costing less to manufacture, providing shorter press cycle times, requiring less resin, and consuming less energy. In addition to providing a vibration device above the slab, the press also includes a second vibration device below the slab, which replaces the massive inertial base of a Breton press. The press can be completely enclosed within a vacuum chamber, and vibrationally isolated from surrounding structures. In embodiments, volume reduction blocks reduce the volume to be evacuated. Embodiments use screw jacks and springs or air bags to provide controlled pressing force and precisely uniform slab thickness. Slabs can be inserted and removed on a conveyor belt, or in rigid, self-supporting trays or molds on rollers.

  • Patent number: 9050748
    Abstract: In manufacturing composite material by curing fluid, strength deterioration of the composite material due to repair before the fluid is cured is reduced. A suction hole is formed in a bag film (3) for sealing a space for fibers being impregnated with resin, after start of impregnation. The suction hole is covered by a plate (56) with holes (57). The resin is sucked from the space through the plate (56). According to such composite material manufacturing method, a defect, which occurs during fibers are impregnated with resin, can be repaired before the resin is cured without causing disorder and damage in the fibers. In a composite material formed from one repaired in the above way, the repaired portion is strong, namely, there is no strength deterioration due to repair after curing, and thus, the material is preferred as compared with a composite material which is repaired after resin is cured.

    Abstract: A method and apparatus for barrier cable anchorage in a concrete formwork such that individual anchors are positioned relative to each other and to the formwork. A galvanized plate is provided with series of holes spaced from a reference point at the plate edge, and a registered assembly of individual anchors are provided in the holes. Female threaded plate caps are secured within the holes for frontal engagement, and a PSR stud is secured to each plate cap on the back side. The assembly is frontally set against the formwork with the reference point spaced from an external datum. The formwork is cured and barrier cables are affixed to the plate caps through the plate by threaded engagement with a barrel anchor and wedge. After tensioning, each cable is anchored to the formwork in desired relative proximity to one another and to the external datum.

  • Publication number: 20140116296
    Abstract: A method can use the ashes of pet or human remains and combining them with natural materials and chemical stabilizers to form, under high pressure, strong building materials. These internment blocks can be formed in an unlimited variety of shapes and weights and can be used to build permanent structures. The ashes are forever protected from the elements and are in a final resting place as part of the memorial structure. The building blocks require zero perpetual care and can last up to or beyond 1000 years. The building blocks can be designed into a lasting memorial of the size and scope desired. In their final cured state, the building blocks can be as hard as stone and impervious to moisture.

  • Patent number: 8663527
    Abstract: A method for arranging engagement means in a concrete body. These engagement means can come into contact with securing means, resulting in a coupling of considerable strength between the concrete part and the said securing means. The engagement means may comprise a screw thread, bayonet-like structure or the like arranged in the concrete. However, it is also possible for the engagement means to be designed as a separate component which is placed into the concrete material. This separate component is then provided with the engagement means proper in that it is provided with a screw thread, bayonet catch or the like. In this way, it is possible to secure construction parts to the concrete part, to hoist the concrete part and to carry out further actions with this part. It is also possible to adjust the concrete part with the aid of adjustment bolts which engage in the engagement means.

  • Patent number: 8632718
    Abstract: The present invention relates to an apparatus and method for forming molded tapered products, such as masonry blocks, whereby high quality finished products are removed from their mold without the need for complex machinery for demolding. The mold may include one or more mold cavities having one or more movable cavity walls. The movable cavity walls may include an end liner having a planar product forming surface capable of moving from a vertical position to an angled position. Tapered products may be formed by moving the mold towards a pallet so that the pallet engages with the end liner and causes the end liner to move from the vertical position to the angled position. Moldable material may then be introduced into the mold cavity and may be allowed to remain in the mold cavity until it is self-sustaining.

  • Patent number: 8628703
    Abstract: A method and apparatus is provided for preventing a composite material used in forming slabs for residential and commercial construction from entering a predefined space that is maintained open for pipes, plumbing fixtures and other conduits. The preform apparatus comprises a body, apron and cover. The apparatus is assembled by placing the preform body in position to occupy a predefined space, press fitting the apron down over and around the body and the cover on top of the body. Thereafter, the composite material is poured around the preform and allowed to cure. After curing, the preform body and the cover are removed, leaving a material free void within and below the predefined space that the preform had occupied. The preform is straightforward, inexpensive to produce, easy to use and is assembled without fasteners and without disturbing the soil below the slab or the moisture/vapor barrier.
