The invention concerns a method for installing a hatch (34) to a subsea structure (10) by connecting the hatch to the subsea structure by at least one hinge (20) having a first mounting portion (21), a second mounting portion (22), a flexible portion (23) interconnecting the first and second mounting portion allowing a pivot connection between the first and second mounting portion. The installation steps comprise inserting a protrusion (23) of the first mounting portion (21) into an installation hole arranged in the subsea structure (10), inserting a protrusion (24) of the second mounting portion (22) into an installation hole arranged in the hatch (34), thereby engaging the first mounting portion (21) of the hinge (20) for anchorage with the subsea structure (10) and engaging the second mounting portion (22) for anchorage with the hatch (34) thereby arranging for the hatch to pivot between a closed and an open position about a pivot axis provided by the flexible portion of the hinge. The invention also concerns a hinge and an assembly for subsea use.

A grid plate for laying mosaic tile preferably includes a grid plate member and detachable tile trowels and/or depth tools. The grid plate member includes a plurality of transverse strips, a plurality of lengthwise strips, and a plurality of retention elements. The plurality of transverse and lengthwise cross strips form a grid pattern. It is preferable that a top of the plurality of transverse and lengthwise strips be brought to an edge to facilitate the distribution of thinset. The plurality of retention elements are integrally molded into the grid pattern to secure the grid plate to a tile cavity.

An architectural structure for constructing a variety of goods in a variety of configurations is provided. The architectural structure includes a plurality of paired slat-like members and a spine configured to hold the plurality of paired slat-like members in an expanded state. Each paired slat-like members includes joined upper ends, joined lower ends and an expandable central region joined to an adjacent paired slat-like members.

A construction system for a wall or floor or roof uses a set of studs having panel engagement features protruding from opposed edges of the stud. Panel elements having apertures receive these features so that they protrude through the panel element apertures. Retainers engage the panel engagement features and press against an outside surface of a panel element and towards the studs with a compression force to form a compression joint. There may be rails to form a mesh with the studs, and the panel elements may not be wide enough to abut each other, narrow panel elements providing sufficient structural strength in combination with the compression joints and the studs.

A grating for use as shelves for pallet racks or heavy-duty racks, having two longitudinal sides and cross members fitted between the longitudinal sides. The, longitudinal sides are in the shape of a profile in cross section. The profile includes at least a first leg and a second leg arranged substantially orthogonal to the first leg. At least two of the cross members have an open profile, in particular a U- or L-shaped profile in cross section, the open end of which is oriented towards the underside of the grating. Each of these cross members has at least two punched recesses at each end. The first leg of the profile is arranged in each punched recess and is firmly connected thereto via a form- or force-fitting connection method. The first leg of the profile has at least one deformation.

A stud rail system comprising at least one stud rail assembly. The at least one stud rail assembly comprises a plurality of rail portions, a plurality of cross portions, where a plurality of sets of support openings are formed in each of the plurality of the cross portions, a plurality of pin projections, where each rail portion supports at least one pin projection, a plurality of support assemblies, and a plurality of support projections, where each support projection is supported by one of the plurality of support assemblies. Each of the support projections extends through one of the support openings in each set of support openings such that the rail portions are rotatably connected to cross portions at a plurality of axis points to allow the stud rail assembly to be reconfigured between a collapsed configuration and an expanded configuration.

Covers for drains, manholes or similar constructions are known which comprise a first grate (10) made of sheet metal and comprising slots (11) and struts (12), said struts having top faces (13) and each strut having side faces (14, 14) made of sheet metal bent with respect to the top face. In order to increase the rigidity it is proposed that at least a second grate (20) is provided, the struts (22) of which are inserted in the slots (11) of the first grate (10).

A method of manufacturing a pre-stressed beam or panel and the resulting beam or panel are described. The method includes providing a timber-based component (1); providing a pre-stressing member (9) arranged along the timber-based component; applying a tensile force to the pre-stressing member (9); providing concrete anchors (11a, 11b) at locations that are spaced apart along the timber-based component (1); coupling the pre-stressing member (9) to the concrete anchors (11a, 11b); and releasing the tensile force on the pre-stressing member (9) to transfer a compressive force to the timber-based component (1) through the concrete anchors (11a, 11b) to form a pre-stressed beam or panel.
