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.

A skeleton unit to mount mosaic plates, includes a main body section and an extension section. The main body section is integrally formed by strip pieces perpendicularly crossing each other to provide a grille shape. The extension section extends out from four edges of the main body section and is integrally formed with the main body section. The extension section includes prolongation pieces which respectively extend out from both ends of each strip piece, and parallel strips which connect with the outside ends of each prolongation piece on the same side and are in parallel with the edges of the main body section respectively. The parallel strip has lap joint hole portions, which penetrates the parallel strips and are used to overlap another skeleton unit. The sum of double the length of the prolongation piece and the width of the parallel strip is equal to the length of the grid.

A structural support having fractal-stiffening and method of fabricating the support is presented where an optimized location of at least three nodes is predetermined prior to fabricating the structural support where a first set of webs is formed on one side of the support and joined to the nodes to form a first pocket region. A second set of webs is formed within the first pocket region forming a second pocket region where the height of the first set of webs extending orthogonally from the side of the support is greater than the second set of webs extending orthogonally from the support.

This invention is designed as a rigid, stationary, non load bearing, exterior wall panel for installation in semi enclosed rooms, additions and outdoor structures such as decks, patios, gazebos, hot tub or spa enclosures, outdoor kitchens and dining areas, and as skirting for the enclosure of spaces beneath elevated constructs such as certain foundations, mobile homes, crawl spaces, porches, stairs, and walkways.

It is an improvement upon conventional wooden lattice panel in that in addition to ventilation, privacy, and prevention of entry by unauthorized persons, the incorporation of wire mesh insect screen prevents entry by flying insects, birds and other animals, blowing leaves and other debris, as well as reduce the quantity of snow and dust blown into said enclosure by wind.

The wooden latticework grid structure secures the screen layered within preventing it from becoming loose or sagging over time, a problem wherefor conventional insect screen is notorious.

Additionally, the segmented connecting lath strips which abutt the long strips of same which complete the gridwork structure and border the edges of said panel provide increased strength, durability, rigidity, structural integrity, and enhanced aesthetics.

Embodiments described herein include systems and methods for efficiently assembling a structure. In one embodiment, a system includes multiple panels, with each panel having a frame made of multiple members. Each member of the frame has at least two pairs of passageways. Each pair of passageways can include two passageways that intersect each other in a perpendicular manner. Furthermore, each passageway may pass through, and be oriented orthogonal to, the longitudinal axis of the member. The first pair of passageways can be spaced a first distance from the first end of the member, while the second pair of passageways can be spaced a second distance from the second end of the member. In some embodiments, the first and second distances are approximately equal to one another. This consistency allows for maximum interchangeability and compatibility of the members and/or panels.

A weighing platform with a lattice load-bearing structure shaped spatially and made of load-bearing elements and connecting elements intersecting with them, affixed to a joint frame, where the load-bearing elements, in the place of intersection with the connecting profiles, have cuts in the shape adjusted to the shape of the connecting elements, and additionally the platform contains at least one load-bearing shell, measurement elements, regulated feet and connectors, where the connecting elements are located strictly in the cuts of the load-bearing structure at the depth, equal to height of the connecting elements and at the same time less than half of the height of the load-bearing elements, while to the bottom of the weighing platform at least two profile panels are fixed, with openings for the screw connectors, to which panels the measurement elements and regulated feet are fixed.

A grating including a bar assembly having bearing bars with a unique cross section connected to one another with crossbars. The bearing bars are generally hourglass-shaped in cross section and include a first region, a second region, and a third region interposed therebetween. The first and second regions flare outwardly away from opposite ends of the third region. The ends of the first and second regions are of a first width and the third region is of a smaller second width. First and second side sections of the third region connect to each of the first and second regions at an angle of greater than 90 degrees. Channels for the crossbars are defined in a first end of the first region of the bearing bar or form a hole extending from a first side section to a second side section of the third region of the bearing bar.
