An insulation system for portable buildings preferably includes a plurality of support struts, a plurality of cross tube clamps and a ceiling sheet. The support strut is preferably a tube having a length, which is substantially equal to a distance between two adjacent rafters. Three support struts are attached to bottom support tubes of two adjacent rafters with two cross tube clamps. The three support struts may also be attached to vertical support tubes of two adjacent rafters with two in-line cross tube clamps. Opposing edges of the ceiling sheet are attached to the bottom support tubes or the vertical support tubes of the two adjacent rafters with at least two sheet clamps. An insulation retention member is placed adjacent a top of the ceiling sheet to prevent insulation from sliding down the ceiling sheet. Two adjacent insulation retention members may be secured to each other with a joining device.

Disclosed herein is a fixing device for supporting sticks. The fixing device includes a vertical stick, a horizontal stick coupled to the vertical stick, a pair of first fixing units, a pair of second fixing units, and fastening means. Each first fixing unit has a horizontal coupling part coming into close contact with the horizontal stick, and vertical coupling parts which are provided on an end of the horizontal coupling part, come into close contact with the vertical stick, and have a space defined therebetween. Each second fixing unit has a vertical coupling part which is inserted into the space of each of the first fixing units and comes into close contact with the vertical stick, and a horizontal coupling part protruding outwards from the vertical coupling part. The fastening means fasten the first fixing units and the second fixing units.

A construction system includes a number of structural elements and a number of connector members for joining the structural elements to one another at virtually any angle. Some of the connector members are configured to connect two or more structural elements at fixed angles to one another, while other connector members allow a structural element to be joined to at least one other structural element at a variable angle.

A coupling apparatus for adjustably mounting modular tooling members having a base member releasably connectable to a slide mount wherein the base member is adjustably located along a predetermined linear path of travel defined by the slide mount. The base member is rotatably adjustable with respect to a midportion via a pair of matingly engaging contoured surfaces. The contoured surfaces are substantially circular having V-shaped teeth extending radially outward. The V-shaped teeth of the contoured surfaces matingly engage and are secured by fasteners to prevent any radial movement of the midportion with respect to the end member. The midportion may also be rotatably adjustable with respect to an end member along a second centerline axis. The midportion and the end member may be adjustably rotated through a pair of contoured surfaces substantially similar to that provided between the midportion and the base member. The end member provides an aperture for releasably connecting a boom rod to the end member.

A space frame has nodes which are made up of juxtaposed plates with the ends of the frame chords sandwiched between them. The chord ends are equipped with collars that have projecting diametrically opposed nibs that fit into corresponding apertures in the plates. The collars may be cruciform in shape, with shoulders between the nibs against which the plates bear to prevent direct clamping of the chords. A second pair of plates to receive the ends of diagonal chords may be bolted to the first pair by a single bolt passed through registering central holes in the plates.

A system for attachment of a fitting to an extruded beam comprises a beam including an upstanding longitudinally-disposed neck having a head comprising laterally-extending flange elements and co-operating attachment means for mounting the fitting, in which the attachment means comprise clamp elements which in use engage the neck of the longitudinally-disposed member from each side thereof, underneath the flange elements, when a clamping force is applied.

A section element for constructing frames, supporting structures and the like made up of a section body (10) having one or more flat surfaces (11) and one or more rounded sectors (12) as parts of a circumference with a preset diameter. In correspondence with each flat surface (11) a longitudinal groove (13) is provided with parallel borders defining undercuts (15). The section body can be connected to other elements by means of clamps (16) each one delimiting at least one cylindrical in diameter housing matching that of the cylindrical surface defined by the rounded sectors of the section body and having at least one additional centering member designed to fit in the groove along at least one of the flat surfaces.

The invention provides a structural building element formed from cold-rolled lightweight sheet steel. The building element may be used as a structural upright or as a beam, and is based generally on building elements with a known C-shaped profile. The profile of the building element of the invention is however based on a continuous curve. Each of a pair of front wall portions extends in a wholly or substantially smooth arc from a central slot opening onto the corresponding lateral side. The rear portion is sinusoidal, comprising a pair of convex wall portions each extending in a wholly or substantially smooth arc from a concave arcuate or substantially arcuate rear central wall portion onto a respective one of the lateral sides.
