Some embodiments are directed to an assembly having a first cardboard assembly member, a second cardboard assembly member and a connection arrangement. The connection arrangement can connect together the first and second cardboard assembly members, and can include a set of first connector elements and a set of second connector elements. Each of the first connector elements can have a first segment fixedly received within the first assembly member, and a second segment that projects from the first assembly member and received within the second assembly member, the second segment extending along a first longitudinal axis parallel to two parallel faces of the second assembly member. Each of the second connector elements can extend along a second longitudinal axis normal to the first longitudinal axis, and be received within the second assembly member and pass through the two parallel faces of the second assembly member.

A G-hook for the mutual releasable connection of two prop portions of a telescopic construction prop has a pin and a hoop. The pin and the hoop are different, separate parts which are rotationally rigidly connected to one another, meaning the pin cannot rotate relative to the hoop because they are rigidly fixed to one another. The pin has a force introduction portion with a surface which is curved regionally and a force removal portion which is diametrically opposite the force introduction portion and whose surface is formed substantially planar.

Containment systems and methods for assembling containment systems include a plurality of posts supporting panels, the posts having top and bottom connectors to connect posts to panels. The tank may be assembled without tools using tabs on the connectors and slots in the panels, with at least one connector having a tab that is bent down after insertion into a slot to secure a panel to a post.

A system enabling the attachment of an object to an element (1) having attachment groove(s), having at least one grooved surface (2) including at least one attachment groove whose mouth (3) is defined longitudinally by two opposing edges (5) that each include an inner salient angle, the system includes an attachment device (6, 7), the element (1), and elements for coupling (8) with the object. The attachment device includes a clamping assembly and a locking element (7) capable of being at least partially inserted in the groove, directly in any of the attachment points along the latter, the assembly being at least partially resiliently or plastically deformable when exposed to a pressure bias exerted by the locking element in order to form, by deforming the material, an anchoring and clamping element capable of anchoring under the edges (5) and/or against the salient angles.

A method of sizing a cavity in a part and a part made from such method. The method includes forming the part having the cavity, including forming a plurality of protrusions extending within the cavity from at least one internal surface of the cavity, the protrusions having distal ends bordering an unobstructed portion of the cavity, the unobstructed portion having an initial dimension at least partially defined by a position of the distal ends, pressing a deforming element against the distal ends of the protrusions to plastically deform the protrusions toward the at least one internal surface of the cavity and increase the initial dimension to a final dimension, and disengaging the deforming element from the distal ends.

A hook terminal is disclosed, the terminal including: a hook unit formed with an upper side-opened fixing groove into which a cable of several strands can be inserted; a fixing unit integrally formed with a bottom side of the hook unit and fixed to a main body; a cable disengagement prevention unit formed at an upper end of the hook unit to inhibit the cable from being disengaged; and a plurality of pressure lugs formed at the hook unit to inhibit the cable from moving to an axial direction by applying pressure to an external surface of the cable, whereby the cable disengagement prevention unit fixing the cable by way of hot pressing work inhibits the cable of several strands from being disengaged and from moving to an axial direction.

A fastener arrangement with a fastener designed for fastening to a substrate via an adhesive agent, and with an object having an object mount, whereby the object mount can be fixed to the fastener fastened to the substrate. The fastener has a reinforcement part made of a metallic material having a flat body with openings and side wall elements adjoining it. The side wall elements are mounted between a retaining ring and wall segments of a ring-shaped holder and are designed for fixing the object mount. There is an adhesive reservoir, the bottom of which facing the substrate is only delimited by the flat body. The top of the adhesive reservoir is delimited by a press-on element; via a displacement of the press-on element in the axial direction, adhesive agent is guided out of the adhesive reservoir solely through the openings in the flat body of the reinforcement part.

An anchor platform assembly for anchoring an object to a raised, generally flat roof-like structure, has an anchor baseplate having a top surface and a bottom surface, and an internally threaded blindbore extending at least partially from the top surface generally towards the bottom surface and fasteners for fastening an object to the anchor baseplate via its blindbore, and for fastening the anchor baseplate to a top surface of a roof-like structure. The assembly is especially intended for supporting, e.g., glass railings on balconies, terraces and flat roofs and for mounted solar panels on both flat and pitched roofs which provides strength and affords watertight performance.

A functional component which is designed to be secured to a holding component by pressing a connecting element into a depression of the holding component. In a non-deformed state, the connecting element protrudes in a press-in direction from a base body of the functional component and is designed to be deformed by applying a force to the base body, so that the connecting element is widened in an end area and the end area is introduced into a wall of the depression. The base body includes a contact surface surrounding the connecting element which abuts a support surface of the holding component in a coupled state of the functional component. A functional module of the functional component is provided by a partial area of the base body facing away from the contact surface.

A condensation heat exchanger including at least one helically-coiled tube, inside which a fluid to be heated can circulate, a deflector, and a shell mounted inside which the tube, the shell having a gas-discharge sleeve having a bottom and a facade for feeding and/or producing a hot gas, inside the shell. The shell comprises a tubular metallic shroud closed at its two ends by a facade and a bottom, wherein the bottom is made of composite plastic, the rear edge of the shroud has a plurality of fastening tongues, the bottom has, at its periphery, a plurality of fastening slots arranged along at least part of its circumference, each fastening slot bordered longitudinally by a first longitudinal rib projecting outwardly, and wherein each fastening tongue is inserted into a fastening slot and folded twice around the first rib.
