  • Patent number: 10604906
    Abstract: A trench box has first and second side panels connected in parallel spaced relation by first and second lateral supports. Each lateral support comprises connection points at each end of each lateral support that connect the side panels to the lateral supports. The connection points maintain the side panels in parallel spaced relation and the lateral supports in parallel spaced relation between the side panels. Each connection point comprises a pivot connection that permits pivotal movement of the side panels relative to the lateral supports about a pivot axis, and a releasable connection spaced from the pivot connection in a direction perpendicular to the pivot axis. The releasable connection is selectively releasable to permit the respective first or second side panel to pivot about the pivot axis such that the panels are not parallel.

An illustrative structural member for constructing such pre-cast building panels is a segmented member made of a rigid material, such as a metal, that is secured to a stud by pressing a member including tangs through a cavity, by the insertion of fasteners through apertures in structural member tabs, or by adhesion or coalescence. The member may include upper tabs and apertures permitting the flow of concrete for additional structural strength. Reinforcement bars can be also incorporated. To reduce heat transfer and promote environmentally responsible and resource-efficient building, a break may be left between the stud and the concrete, with the break possibly filled by an insulative material.

    Abstract: Pre-cast concrete stairs, molds for making pre-cast concrete stairs, and methods of casting pre-cast concrete stairs are provided. The stair is constructed with two beams that are cast with the stair steps as an integral monolithic structure. One of the beams (integral down edge beam) projects below the steps on one side, and the other (integral up edge beam) projects above the steps on the other side. The weight of the stairs and the weight of traffic on the steps creates compression on the tops of the integral down edge beam and integral up edge beam, and tension on the bottoms of the integral down edge beam and integral up edge beam, which enhances the combined strength of the beams. The asymmetric orientation of the members creates a stronger cross-section than if the beams were in the same plane horizontally, allowing greater load handing capability. Lightweight steps are suspended between the two beams.

The brick of this system is a rectangular block with horizontal and vertical protuberances and cavities which permits horizontal and vertical interlocks with the adjacent bricks of the wall. The brick is also perforated by holes which are aligned with the holes of the vertically adjacent bricks of the wall, thus forming a continuous vertical hole that goes throughout the entire height of the wall. The rod of the system crosses the bricks through the continuous hole of the wall.

  • Patent number: 7028439
    Abstract: A wall system employing channel-reinforced lightweight precast concrete wall panels. The precast wall panels include a concrete slab, a pair of spaced-apart elongated generally parallel metallic side channels, and a plurality of spaced-apart elongated generally parallel metallic attachment channels. The side channels and attachment channels are partially embedded in the slab and extend substantially perpendicular to one another. Each wall panel can be coupled to a support wall by extending self-tapping screws through metallic wall framing members and the attachment channels at locations where the framing members and attachment channels cross.

  • Patent number: 6951080
    Abstract: A culm block and a method of manufacture are disclosed. The culm block comprises a plurality of straw stalks that are “vertically aligned”, i.e., perpendicular to the ground when the block is laid flat. The straw is treated with a moisture inhibitor and/or a binder. Throughholes, which may have tubes associated therewith, are formed into the top and bottom walls of the culm block. A lath or external strapping sleeve is wrapped about the front, rear, and side walls of the block for added structural support. The method of manufacture may include sorting the stalks according to length, checking the stalks for moisture content, and drying the stalks depending upon their moisture content prior to compression and formation.

  • Patent number: 6915614
    Abstract: A bricklaying structure, a bricklaying method and a brick manufacturing method that is adaptable to a variety of architectural details. Each brick is provided with a bolt hole and through-holes. The bolt hole has a diameter which allows a bolt to extend therethrough and the through-hole has a diameter for containing a nut. The bolt hole and through-holes are arranged on a longitudinal center line of the brick, and a center of the bolt hole, centers of the through-holes and respective end faces of the brick are spaced apart an equal distance from each other in a longitudinal direction of the brick. The bricks and metallic plates are vertically stacked and the bricks are integrally connected under pre-stress with each other by tightening the bolts extending through the vertical bolt holes.

  • Patent number: 6910305
    Abstract: A system for walls and structural slabs is disclosed. It consists of units of a pre-case reinforced concrete element has a special form design, fabrication methods and utilisation. The element has a circular section, variable lengths and flat surface on the top and bottom sides (2). It has a sectional area of 4170 sq mm. The optimum preferred dimensions of the cross section are 64 mm high and 75 mm wide (1). The element has an optimum shape that reduces the materials used yet provides the structural performance required. When stacked vertically between two structural framing columns, the elements form non-load-bearing walls system(3). The elements form structural diaphragm when horizontally laid side by side in a butt-jointed manner, supported on both ends by means of structural framing beams. Plain concrete topping to the necessary thickness is cast over the diaphragm/elements, forming an integral reinforced concrete structural slab system (4). The elements are fabricated mechanically or manually.

  • Patent number: 6877283
    Abstract: Earthquake resistant blocks or discrete structures are manufactured using pieces of low quality construction materials such as slag, concrete waste, chipped stone, Sirasu, etc. The pieces are placed in a mold and arranged in the mold so that they are in intimate contact with the mold sides and with each other throughout the mold. Once positioned, mortar or other concrete binding material is poured in to retain the low quality construction materials in contact with each other. When the blocks or discrete structures are placed adjacent to each other, such as when constructing arches, they absorb or dissipate the shock and vibration energies by having the sides of the blocks, and in particular the low quality materials within the blocks, in firm frictional contact. The amount of concrete used is greatly reduced and local and normally scrap material can be used and recycled.

  • Patent number: 6860075
    Abstract: A device for surface-treating, coating or producing construction elements in a continuous process has production chambers arranged successively closely adjacent to one another in a direction of transport of the construction elements through the device. Each production chamber has opposed ends with through openings and is connectable to a vacuum source. Each production chamber has a stationary chamber part of reinforced concrete and a detachable chamber part of reinforced concrete connected to the stationary chamber part, wherein the stationary chamber parts have first edge areas and the detachable chamber parts have second edge areas, wherein the first and second edge areas have sealing surfaces sealing the stationary and detachable chamber parts relative to one another. Each production chamber has walls defining a hollow interior, wherein the walls consist of a metallic skin anchored in the stationary and detachable chamber parts, respectively.
