The present invention discloses a three-dimensional lightweight steel framing system formed by bi-directional continuous double beams. The three-dimensional lightweight steel framing system comprises beams, purlins, columns, wall bodies, floor slabs and lateral resistant mechanism comprises of diagonal support or bracing, wherein the beams are continuous double beams, and the continuous double beams are formed by combination of identical or different continuous single beams, and the continuous single beams are respectively arranged at the both sides of the columns, and the single beams are kept continuous at the junctions with the columns. The three-dimensional lightweight steel framing system simplifies the production of the lightweight steel member, and simplifies the on-site assembly by using bolts and nuts.

Further, the apparatus may include a plurality of top plates. Further, the apparatus may include a plurality of studs. Further, each stud of the plurality of studs may include an elongated stud body having an upper stud end and a lower stud end. Further, the apparatus may include a plurality of rafters. Further, each rafter of the plurality of rafters may include a first slab body. Further, the each rafter may include a first cuboidal body. Further, the apparatus may include a plurality of braces corresponding to a plurality of brace lengths.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

A roofing system for forming a roof includes a plurality of tiles. Each tile has a frame at a perimeter of the tile, and the frame includes an upstream element, an opposed downstream element, and opposed first and second side elements, thereby bounding a central panel area. Each tile further includes a side trim, a batten, and a ridge cap. When the tiles, side trim, batten, and ridge cap are arranged to form a roof, the batten is secured at a lower edge of the roof and directed upward to receive the downstream elements of the tiles, the side trim is secured at a side edge of the roof and directed laterally to receive one of the first and second side elements of the tiles, and the ridge cap is secured at a ridge of the roof and directed downward to lap over the upstream elements of the tiles.

A large-angle sloping roof steel structure connected to a main body structure, including: an intermediate platform, inclined main supporting steel columns circumferentially connected at four corners of the intermediate platform, constructing steel columns and wind-proof surrounding beam connected between top ends of the inclined main supporting steel columns, where roof purlin are connected between the adjacent inclined main supporting steel columns at intervals. The invention provides a top-down inverted construction method for a large-angle sloping roof with a steel structure as the main structural form. By using the method, the operation safety of an inclined main stressed vertical member during the installation process can be ensured, and the investment of supporting measures is reduced by preferentially installing the intermediate platform, thus effectively ensuring the installation progress, quality and safety of the sloping roof steel structure. The present invention can be widely applied to sloping roof construction.

A reinforced beam system comprises at least one pair of angularly spaced, corner-connected beams configured with two oppositely oriented triangular closed head portions, and a web interposed between head portions; a plurality of reinforcement elements forcibly contacting an interior wall of the corresponding head portion; and for each pair, at least one angled connector. A first leg of the angled connector abuts the flange of a second head portion of the first beam and is connected to a first reinforcement element inserted within the second head portion of the first beam, and a second leg of the angled connector abuts the flange of a first head portion of the second beam and is connected to a second reinforcement element inserted within both the first head portion of the second beam and a first head portion of the first beam. A beam system in one embodiment is devoid of reinforcement elements.

Pyramidal housing autonomous and suitable for different environmental conditions. Its pyramidal structure (1) is made up of metal profiles (10) that include corner pillars (10a), side pillars (10b), beams or cross structures of mezzanine (17)(19) and rafters that form the openings (4), being the pillars anchored to the foundation beam (13); over this structure, the outer covers (15) that form the pyramidal walls (15a) are mounted; in the blind sections of the outer cover (15) of the upper floor there are mounting supports (32) for arrangements of solar panels (30), while at the apex (12) there is a wind energy generator; other blind sectors allow the mounting of a solar heater (50).

A modular perimeter frame system (10) is described for forming a perimeter frame (11) used in the construction of floors, walls and roofs of buildings The modular perimeter frame system has a first modular sub-frame (16) having one or two blunt end portions (26, 28), and a second modular sub-frame (18) having one or two overhang end portions (36, 38). The blunt and overhang end portions are so dimensioned and shaped as to facilitate a continuous abutting engagement between at least two surfaces which meet at a corner of the blunt end portion and at least two surfaces which meet at a corner of the overhang end portion.

This application is an accumulation of various patent pending applications showing multiple configurations for connecting metal framing components together where the metal framing members are self-locking connectors that intersect, overlap, between other securing the metal support members together. The connections between the metal framing members uses various types of notches in the support members and notches in the metal framing member to secure metal framing together by using hook fingers, hook tongue, hook receivers, ledges, and tabs to secure the crossing members together forming the self-locking connections. The metal framing components have various longitudinal ends allowing where the longitudinal ends can have the same configuration or different configurations and still be an overlapping interlocking connection.
