A joint connection structure of a building framework includes a column assembly including a column and a pair of side plates attached to the column on opposite sides of the column and extending laterally outward from the column. A beam assembly includes a beam having an end portion received between the side plates. At least one of the column and the beam has an opening in an area between the side plates to provide access for bolting at least one of the side plates to one of the column and the beam. The opening is free of a fastener extending through the opening when the column assembly is attached to the beam assembly.

A composite structural member for a building structure comprises a first elongate portion having a first end region and a second end region and a second elongate portion having a first end region and a second end region. The second end region of the first elongate portion is connected to the first end region of the second elongate portion so that the composite structural member provided thereby is substantially longer than either of the first and second elongate portions. The first elongate portion may comprise a first member suited for resisting high magnitude forces and the second elongate portion may be a second member, less well suited for resisting high forces but having lower cost per unit length. The composite structural member may be a rafter, especially a rafter of a portal frame.

The invention relates to a building structure comprising pillar units, beam units including main beam units and floor slab units, the floor slab unit comprises a floor slab template layer and a floor slab framework unit; the beam unit comprises a beam template layer of concrete and the beam framework unit; the pillar unit comprises a pillar framework unit, the pillar framework unit comprises a pillar keel unit and support legs; the pillar framework unit comprises a pillar keel unit and support legs; the longitudinal section steel major keels supported on the main beam major keels and the steel bars protruding out of the floor slab template layer in the side direction are placed above the main beam units; the cells are formed between the adjacent beam units; more than one floor slab units are installed in each cell. The advantages of the invention are no support frames, no removing the template.

A system for providing an angled construction or bent beam construction. Such system may include a first beam comprising a first elongated beam segment having a first interlocking joint portion at one end, and a second beam comprising a second elongated beam segment having a second interlocking joint at one end, wherein the first interlocking joint portion is configured to rotatably couple to the second interlocking joint to form a rotatable joint such that the angle between the first beam and the second beam is adjustable.

Flexible extrusions of selected die patterns may be slid or snapped together to create bundles of slidably-interlocked extrusions that may be used to create structural components for architectural and a plurality of other construction purposes. Components such as standard rectangular construction beams, arches, domes, architectural trees, cylinders, molds, puzzling mazes, furniture, rollercoaster track, and other applications are illustrated and described in embodiments herein. Bundles of slidably-interlocked extrusions may be formed into a straight beam, bent into an arch, or twisted into other forms as desired. Bundles of slidably-interlocked extrusions may for example, comprise subsets of different length bundles of extrusions that may extend the length create long-span support beams or that may branch away at an angle from the starting beam to form a treelike structure.

A support column extends in a longitudinal dimension and includes a plurality of outer hollow longitudinal structures. Each longitudinal structure defines an interior passage extending along a length of the longitudinal structure. The support column includes a plurality of inner members. The plurality of outer hollow longitudinal structures are aligned end-to-end along a single axis. The interior passages of the plurality of outer hollow longitudinal structures cooperate to define an interior passage of the support column. The inner members are aligned end-to-end along the single axis within the interior passage of the support column so that opposed longitudinal ends of each of the inner members extend to respective longitudinal ends of each adjacent inner member. At least one end of at least one inner member is longitudinally offset from every longitudinal end of the plurality of outer hollow longitudinal structures.

A device for strengthening and/or rigging trusses includes at least two connecting elements, which connect at least two parallel truss pipes of the truss. On these connecting elements an attachment unit provided between at least one pair of truss pipes, to which mounting structures can be attached.

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.

A bracket is combined with a rail that is to be attached to an elongate structural element by the bracket. The bracket includes a body and a bolt. The body is configured for attachment to the elongate structural element. The body defines a shoulder from which the rail is attached so that the rail is connected to the element. The bolt is engaged with the rail and is movable to engage the body. The body has a threaded passage to engage the bolt to fix the rail to the body.

The present invention relates to using interlocking spacer braces between support members to construct wood and metal framed walls, floors and building trusses. Spacer braces have indentations, extensions, fingers that interlock horizontally, vertically or diagonally between support members. The spacer braces can form diagonal and lateral wall bracing, diagonal and vertical chords within building truss with either horizontally or vertical orientations, beams, hold-downs and shear walls. The spacer braces can be installed between wood or metal framing members.
