Abstract: A double tie includes a pair of upper and lower straps connected in parallel relationship by a pair of vertical plates attached to the outward ends of the straps. The plates are oriented orthogonally relative to the straps to form a general "T" shape. A pair of stop straps are mounted on the plates intermediate the upper and lower straps, and projecting towards one another. The stop straps have orthogonal heads spaced inwardly from the plates a distance to retain a form panel between the head and plate. Each upper and lower strap has a hinge formed at each end, the hinges at each end of the upper and lower straps being coaxial and parallel to the plates, such that the upper and lower straps may be pivoted from a position generally orthogonal to the plates, to a position generally parallel to the plates.

Abstract: A modular structure for constructing houses is designed for children to play. The structure includes moulded material panels which are connected with the assistance of corner parts through conjugated members built into the panels. The panels have an outer embossed surface resembling stonework, windows and door openings in which the relevant leaves or panes are articulated. The facade parts form a top angle for supporting saddle roof parts above. The modular structure is used for mounting houses for children to play within and it is accessible for children. The house may also have auxiliary rotatable simulated domestic elements, such as a vertical mirror that rotates down to be a horizontal table top.

Abstract: A box beam incorporating an I-joist. A set of such box beams makes up a portion of the base for a shelter and provide receivers in which prefabricated wall partitions are slidingly engaged. The I-joist or I-beam includes an elongate web, two opposite flanges, and at least a first outer elongate plate member which runs parallel to the web and is fixed to and between faces of the flanges. With a single outer plate member extending beyond the upper flange, an L-shaped receiver is formed for receiving outer wall partitions which may be placed into such receiver from a horizontal direction, without manipulating the wall partition up and over and down into the receiver. With a pair of outer plate members extending beyond the upper flange, a channel receiver is formed. I-beam structures having the channel receiver are placed in the interior of the base for interior wall partitions. The I-beams support a floor and such outer and inner wall partitions which may interlock with each other.

Abstract: A strengthened masonry reinforcement device is used in construction to strengthen the courses of laid hollow block. The masonry reinforcement device is fashioned with ends and a strengthened trough. When used in the construction of a wall the masonry device with the strengthened trough will be light-weight and retain cement to bind hollow block in a lower course to hollow block of an adjacent upper course.

Abstract: A protective hole cover having a plurality of slots along which slide friction locks secured by screws. Since the slots extend radially outward, the protective hole cover may be releasably secured to holes of varying dimensions. To secure the hole cover, two of the friction locks are positioned at an appropriate distance from the center of the protective hole cover and secured by the screws extending through the slots and into the friction locks. The protective hole cover is then placed within a hole with the two friction locks contacting an interior surface of the hole. The third friction lock is then slid outward to engage the interior surface of the hole as well and the friction lock is thereafter tightened to secure the protective hole cover over the hole. When it is desired to remove the protective hole cover, one of the screws 40 is loosened and the friction lock slid inward toward the center of the protective hole cover.

Abstract: A corrugated board structure including an upper layer of corrugated board, a bottom film and a middle layer of PU foam. Each side of the bottom PVC film is formed with an inward bent upright folded wall which, during the foaming and expansion procedure of the PU foam, restricts the foaming space so as to continuously produce solid foam structure. The middle PU foam makes the upper and lower layers tightly adhered to each other as an integral body. An edge of the projection on one side and an edge of one of the front and rear ends is free from any PU foam and bottom film so that two adjacent corrugated boards can be overlaid and connected.

Abstract: The present invention is a reinforced wall patch comprising a sheet of mesh material, such as fiberglass mesh, and a sheet of fibrous material, such as paper, attached to the sheet of mesh material whereby the bendability of the mesh material is enhanced. Thus, the present wall patch may be effectively used as a cornerpiece in applications which require enhanced flexibility. A sheet of protective material may be attached to the surface of the mesh material in such a manner so that the mesh material is arranged between the fibrous material and the protective material.

Abstract: A construction element, such as a supporting element for a retaining wall, has a casing which is at least partially permeable. The casing contains a block-shaped, granulated, bulk or porous filling material. The casing has two layers including a relatively rigid grating part (GT) for strength and a relatively flexible, finer meshed netting part (NT) for containment of filling material. The casing is designed as a closed hollow body which is coupled to the filling (FL) so as to form a substantially self-supporting construction element which is completely prefabricated.

Abstract: A tongue and groove deck plank made from a wood replacement material. The deck plank is substantially hollow, and generally rectangular. It has a horizontal top and bottom, a tongue on one edge, and a groove on the other. When the tongue of one deck plank and the groove of another are placed next to one another, a space is maintained between a portion of the tongue and a portion of the groove. A deck may be made from the deck planks. The deck has a support, and at least one wood replacement deck plank attached to the support. The deck preferably includes a starter strip attached to the support.

Abstract: A tank system includes a tank, a rainwater feed mechanism and a run-off for contaminated water.

Abstract: A drainage track useful in combination with exterior insulation and finish systems including a clog-resistant drainage channel so that water collecting behind the exterior insulation and finish may drain from the structure. The drainage track, in a preferred form, is extruded from PVC and defines a substantially L-shaped configuration in cross-section. An elongated, relatively tall flashing leg is provided for attachment of the drainage track to the structure such that all water resistant material and insulation laps over the flashing leg to direct water into the drainage channel. Finish apertures are provided through a portion of the drainage track so that exterior finish such as, for example, stucco, will readily adhere and bond to the drainage track.

Abstract: An upright cylindrical pier foundation is constructed of cementitious material. The lower end of the foundation has a plate or circumferential ring fully embedded therein and long circumferentially spaced rods or bolts have their lower ends anchored relative to the ring. The upper ends of the long rods project up outwardly of the top of the foundation. The rods are shielded over substantially their entire length against bonding with the cementitious material to allow the rods, when heavily tensioned, to stretch within the cementitious material. A heavy flange, which may comprise the base flange of a tubular tower, is positioned downwardly upon the upper end of the foundation with the upper ends of the bolts projecting through holes provided therefor in the base flange.
