The present invention comprises a concrete building system with a method for fabricating composite panels using an improved design plastic connector and assembling them at the construction site to a structure which will be shotcreted on both sides to a concrete building which is highly insulated, is fire and termite proof, hurricane, earthquake and flood resistant and fulfills the requirement for flexible design. The Composite Panels are composed of two concrete layers, enclosing an insulative foam core. The skins are reinforced with wire mesh as structurally required and are connected through the foam core by structural highly insulative plastic connectors using the snap connection on both ends of the connectors so they form a tri-dimentional system and hold the wire mesh in place for the onsite shotcrete application, which includes an application of fiber for shrinkage and cracking. This replaces the welded wire fabric use for secondly reinforcing and let the wire mesh reinforcing only related to the structural strength of the composite panel. The plastic connector guarantees that no thermal bridging occurs like in other systems also the inside layer of the shotcrete panel.

The environmental protection shelving combination of the present invention includes sleeves and panels made of corner protection paper for support and plastic connector sets used for coupling the sleeves.

Accordingly, not only the costs of material, conveying and assembly can be reduced, the pollution to the environment also can be minimized.

A novel building construction is described for exterior building walls. The construction comprises an interior frame formed of a plurality of laterally spaced studs or beams, a layer of rigid insulation adjacent to the exterior side of this steel frame, exterior building cladding adjacent the exterior side of the rigid insulation and a plurality of low conductivity connectors, e.g. insulating plastic connectors or thin metal strips having an insulating plastic foam coating, extending through the layer of rigid insulation and connecting together the exterior cladding and the interior steel studs or beams. Vertical channels are formed adjacent both the inside and outside faces of the insulation layer to remove moisture. This provides the required structural strength with a minimum of thermal conductivity from the warm side to the cold side of the building envelope, while providing exterior drain channels and interior moisture removing channels.

A concrete footing for the construction of a wall is created by the placement of a guide member with a series of very large holes, which is supported with adjustable threaded stake supports. This guide is situated along a location which will become the top surface of that footing, typically within the confines of a footing trench. Concrete is conventionally placed via a pump through the large holes thus filling the trench void up to the guide element underside. Adjacent guides are attached with plastic connectors which also fixture vertical reinforcing elements which disassemble to strip guides, typically immediately after concrete has been placed.

A living hinge structure has two plastic side sections and a plastic connecting section, wherein the plastic side sections are integrated with metal supports so as to enhance the strength of the living hinge structure. The metal supports can be metal inserts bonded to the plastic side sections in an over-molding process. Each of the metal supports can be located on the outside surface or the inside surface of the plastic section. When the metal sections are located on the outside surfaces, they can be used to restrict the opening angle of the hinge. The metal supports can also be a part of a device that uses the hinge for mechanically coupling two device parts. As such, the living hinge is directly integrated into the device without the need for post-assembling by using screws, adhesive, welding or heat stacking.
