Abstract: Composite panel for building construction comprises a first layer of honeycomb structure, and a load-bearing layer attached to the first layer of honeycomb structure contiguously or at distance for carrying external load of the composite panel in a lateral direction of the honeycomb structure.

Abstract: A connector for connecting formwork panels in a formwork assembly comprises a first elongate portion having triangular cross-section, a second elongate in sliding contact with the first elongate portion, and a third elongate portion in sliding contact with the first elongate portion. A guiding device is coupling the first elongate portion, the second elongate portion, and the third elongate portion. An actuator drives movement of the second elongate portion and third movement along the guiding device. The second elongate portion and the third elongate portion are movable toward and away from each. The second and third elongate portions also each being movable relative to the first elongate portion.

Abstract: A method for successive concrete of high vertical walls by using a climbing shuttering system having a support structure on which various concrete shuttering elements are loaded hanging downwards. The top supporting carrier and the climbing shuttering system can be supported on completed wall sections. There is at least one lifting device that brings about a relative movement between the too supporting carrier and a lower support carrier of the climbing shuttering system. The shuttering elements can be positioned in a substantially even surface to form a shuttering and at the same time the top supporting carrier can be positioned on the shuttering elements placing them respectively against the walls.

Abstract: A compensating element (23) is permanently connected to a first formwork element (21) and a second formwork element (22) wherein the compensating element (23) has openings formed like elongated holes on the side along its axial direction through each of which one tube penetrates which terminates in one housing each on both sides of the compensating element (23). The housings can be displaced along the tube and be moved via a rod assembly. When the compensating element (23) is displaced into a formwork dismantling position, the formwork elements (21, 22) and the compensating element (23) are released from the concrete surface and the entire device can be moved.

Abstract: The invention concerns a climbing shuttering system having a supporting structure on which various concrete shuttering elements are loaded hanging downwards. Said structure is connected at least to a first top supporting carrier that underprops it. The top supporting carrier has the means, to support it laterally to a completed wall section. The climbing shuttering system also has at least one lower supporting carrier, that can be supported on a completed wall section. There is at least one lifting device that brings about a relative movement between both supporting carriers. According to the invention, the top supporting carrier is designed to be supported on a substantially even surface.

Abstract: A portable concrete molding apparatus for forming concrete structures of a predetermined configuration, either on-site or at a central manufacturing facility. The apparatus includes a trailer having furnace plenum bounded by a pair of fixed walls. Each fixed wall cooperates with a movable wall for forming a mold therebetween. Each movable wall includes a concrete inlet for introducing concrete into the bottom portion of the mold. The fixed and movable walls include push-off valves for ensuring separation of a concrete structure from the mold walls, as the mold walls are separated.

Abstract: A plastic buck which is used to form an opening in a wall to be constructed of concrete or other flowable building material. The buck includes flanges on each side which contain mounting holes used to mount the buck to a wall form. Additionally, the flanges include holes for mounting fasteners onto the window buck thereby enabling the fastener to be cast within the concrete wall. The buck includes bracing members configured within the buck to prevent the forces of the building material on the window buck from causing unacceptable deformations in the buck as the wall is poured. Handles are also attached to the window buck to facilitate installation and removal of the buck. A plurality of knock blocks are located on the buck such that one may apply impact forces to the buck to remove the buck from the concrete wall after the concrete has set. Since the buck is constructed of plastic or other nonporous material, removal of the buck from the poured wall is facilitated.

Abstract: Rammed building walls having an earth core and integral cement jackets are formed by placing a rectangular earth hopper within a rectangular wall moulding cavity that is defined by formwork members which are aligned with an underlying foundation. The hopper is filled with earth while outside of the moulding cavity and has a trapdoor as its bottom. The moulding cavity has a substantially greater width than the width of the hopper so that jacket cavities are formed on either side of the hopper. A pair of tiltable cement hoppers, filled with concrete or a sand and cement mix, are mounted on the earth hopper and are tiltably unloaded into the jacket cavities. The trapdoor is then released so that the earth slides downwardly and laterally, and the hoppers are lifted as a unit out of the moulding cavity while the earth fills a core cavity between the mix-filled jacket cavities. Both the earth and mix are then rammed simultaneously.

Abstract: A traveling mold for forming a pre-cast, box-like concrete structure has movable frame means for supporting the mold. Inner and outer wall forms of the traveling mold are movable, vertically and transversely, away from a formed reinforced concrete wall section, after the wall section has hardened sufficiently to be self-supporting. A method for forming a pre-cast reinforced concrete building structure having a floor and at least one upstanding wall, using the traveling mold, is also described.

Abstract: The machine for prefabricating components comprises at least one fixed frame having an internal vertical wall and an intermediate movable frame having at least one vertical wall opposite and variably spaced apart from said vertical wall of the fixed panel. The space between the opposed panels may receive ready-mixed materials, for formation of the prefabricated components, from one or more mixing vessels mounted on the intermediate frame. The spaces are further delimited by panels which may support reinforcing meshes for incorporation into the prefabricated components or rods for producing perforated prefabricated components.

Abstract: The invention describes a method of constructing a building involving the assembly of a rigid skeletal framework of struts defining the contours of the desired building which is for example domed, or part-barrel shaped. A membrane or envelope of plastics material is inflated within the framework to lift the struts from a state of compression under their own weight into a state of tension. The membrane is then coated on at least one side with settable material such as concrete or other glass fibre reinforced material and the membrane deflated when the material has set. In an example of the invention, support zones at the junctions of the struts support the set material.

Abstract: A concrete wall form includes a support structure comprising a beam capable of functioning as a stringer or stiffback and which includes a bolt holding channel, a nailer channel and an internal channel for telescopically receiving an extension splice. A tie rod locking system is associated with the support structure for readily adjusting the forms.
