  • Patent number: 10914082
    Abstract: A mesh tape bonded to the outer edge or outward side of sheet panel products. The mesh tape is applied so that the tape overhangs the edge of the panel for the purpose of adjoining to the adjacent panel following installation of the panels at a job site. The mesh may be applied to two edges of the sheet panel, one along the panel width and another along the panel length. When installed, the panel edge with the mesh tape applied is overlapped with the edge of an adjacent panel that does not have tape applied, both along the length and width, thus allowing for a faster, more robust and reliable installation of panel sheathing.

  • 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: 9221191
    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.

  • Patent number: 8734705
    Abstract: Disclosed are apparatus and corresponding methodologies for providing a base support, such as including concrete, and used such as for a wind-driven generator. Precast concrete cylinders are stacked in place upon a platform that may be partially precast and partially cast in place during assembly and supported, in certain embodiments, by plural concrete legs, the other ends of which are supported on a unitary or subdivided concrete foundation. In other embodiments, the platform may be supported by ribbed concrete panels. The concrete cylinders are glued together using an epoxy and then secured by an internal vertical post tension system extending from the platform to the upper most cylinder. Methodologies and apparatus for fabrication of concrete structure used in constructing the base support are also disclosed, with a focus on staves and various ring piece constructions.

  • Patent number: 8713894
    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.
