Abstract: A concrete forming panel system having at least two rectangular panels wherein each panel has a pair of spaced apart sidewalls. Each panel has at least one opening along each sidewall and the panels are adapted to be positioned in a side-by-side relationship so that one sidewall of each panel abuts against the sidewall of the adjacent side panel and, upon doing so, the opening in one sidewall of the first panel registers with the opening in the abutting sidewall of its adjacent side panel. An elongated pin is slidably mounted to each panel and movable between an extended position in which the pin extends through registering openings on adjacent panels, and a retracted position in which the wall pin is retracted from said registering openings. A latch is pivotally mounted to the pin so that, with the wall pin in its extended position, the latch pin extends through a transverse opening in the pin to lock the sidewalls of the adjacent panels together against relative movement.

Thus, a mounting structure is provided whose manufacture is relatively easy and cost-efficient.

Abstract: The invention relates to a panel with coupling elements, which are designed in such a manner that two panels can be connected to one another by a form-fit connection at the same time in a first direction perpendicular to the common joint and in a second direction parallel and perpendicular to the common surface of the panels. The invention relates especially to a laminate flooring. The panel according to the invention provides one coupling element, which is designed in such a manner that two panels can be connected to one another especially by form-fit connection in the direction along the common joint formed by the panels. The form-fit connection along the common joint according to the invention therefore achieves greater security during assembly with reference to any enlargement of the cracks and inaccuracies when laying parquet flooring.

Abstract: A joint apparatus for joining two objects together with end faces in face-to-face engagement includes first and second flat plates for attachment to faces of the respective objects adjacent the end face. Each plate has a first side edge for facing the first side edge of the other plate when secured to the respective object, and the first side edges each have at least one tongue and recess positioned for alignment with the recess and tongue of the other plate, respectively.

Abstract: An improved and strengthened wide board composed of multiple edge joined narrow boards for use in commercial and residential construction is disclosed. These wide boards are typically used for purposes such as shelving, stair treads, or other purposes where they may be appropriate. The improved wide board is made by drilling or boring holes from edge to edge through the width of each narrow board, with the exception of the leading narrow board in each wide edge joined board, in a manner that accommodates screws or fasteners, which act to securely clamp or pull the boards together. These holes are step-drilled in a manner that allows the head of the screw or fastener to be recessed below the edge of the narrow board, in order to attain a smooth or flush surface between boards. The hole then steps down to a smaller diameter to accommodate the shank of the screw. A screw may then be inserted in a manner that its shank end exits the hole and “bites” into the edge of the next adjacent board.

Abstract: A wall for the booth of a coating plant is composed in a known manner of individual wall elements (1, 2). Each wall element (1, 2) comprises a load-bearing frame (3), which is formed from vertical posts (4, 5) made of sheet-metal sections and horizontal crosspieces (6, 7, 8, 9). The zones spanned by the posts (4, 5) and the crosspieces (6, 7, 8, 9) are covered by plates (10, 11, 12). At least the vertical posts (4, 5) have a section whose basic geometric shape is rectangular, although two of the sectional legs (15, 16), namely in each case the outer leg which is vertical to the associated plate (11) and the outer leg (16) which is parallel to the plate (11), do not extend over the entire length of the corresponding side of the rectangle. The interior of the posts (4, 5), in which fixtures and fittings can be installed, is thus accessible.
