A permanent spacing beam for the rapid deployment of roofing trusses on site. Such permanent spacing beams and truss ties as described may utilize a mount end, a retention end, and an elongate portion which spans the distance between the mount end and the retention end. The mount end may have a mount slot and the retention end may have a retention slot. The mount slot and the retention slot may be configured to permanently couple and mount to a first truss timber stud and an adjacent truss timber stud used in residential and commercial roof construction. Such a configuration results in a permanent truss tie being spanned between two roofing trusses thereby creating a more robust and sturdy roof construction.

At least first and second rows of panels may be mounted onto, or to form, at least part of a pitched roof, wall or other structure by mounting a panel support framework onto an underlying structure and arranging the panels so that each panel on the second row is offset upwardly relative to each panel on the first row in a stepped fashion.

An interlockable structural panel with a channel cross-section including a base and first and second side wall forming the sides of the channel, wherein an end of the first side wall distal the base is curved as a first arc directed away from a central portion of the channel and an end of the second side wall is curved as a second arc directed towards the central portion of the channel and wherein a straight section extends from the end of the second arc distal the base. Also methods for forming interlockable structural panels and for forming curved interlockable structural panels for constructions including roofs.

A dome- or sphere-shaped multipurpose building is disclosed, which is a prefabricated quickly erected structure and can be used for erecting the buildings of various functional purpose, of different number of floors, both heated and unheated, including residential buildings, cottages, industrial, administrative, sport, temporary portable buildings, arch structure. Technical result of the claimed invention is to reduce the material consumption, installation time, increase the strength and stability of the building, including under conditions of asymmetrical and dynamic loads, and to increase energy efficiency and translucence of the building. The multipurpose dome-shaped building comprises a bearing frame made in the form of at least three pyramidal volumetric trusses arranged symmetrically with respect to the base center and rigidly connected to each other in the upper part by at least one horizontal beam, and wherein the volumetric trusses are arranged in such a way that the horizontal distance between closest posts of neighboring volumetric trusses remains the same over the entire height from the base and up to the top of the neighboring trusses.

A load bearing structure including a first fixed net layer, a second fixed net layer and a non-linear structure in between. The first fixed net layer may include a first layer of flexible, drapable fabric and a fixing material that fixes the shape of the first layer of flexible, drapable fabric. The second fixed net layer may include a second layer of flexible, drapable fabric and a fixing material that fixes the shape of the second layer of flexible, drapable fabric. The non-linear reinforcing structure may be in communication with the first and second fixed net layers and may be configured to share with the first and second fixed net layers a load applied to the load bearing structure.
