A pre-engineered metal skeleton for the reinforcement of a concrete structure comprises a plurality of elongated primary beams and a plurality of interconnecting members each formed from flat sheets of metal. The interconnecting members frictionally interlock with co-operating receiving portions formed on the primary beams to thereby secure the primary beams and the interconnecting members one to the other without requiring supplemental fastening means. The plurality of interconnecting members have both their major axis and their minor axis oriented substantially transversely to the major axis of the elongated central main body portion of the primary beams.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

A tornado resistant/proof residential housing unit that is built to withstand natural disaster conditions resulting from tornadoes, violent storms, and fire. An internal concrete reinforced core layout gives the unit its structural strength, as well as the versatility needed to face natural disaster conditions while providing absolute resistance to heavy winds such as those caused by a tornado. The unit has an external facade which mimics the exterior appearance of a typical subdivision home.

A modular assembly for forming a shear wall includes a modular frame having a first side, and formwork. The formwork has a reinforcing bar cage and a first wall each coupled to the first side of the modular frame. The first wall is disposed between the reinforcing bar cage and the first side of the modular frame.

A concrete form panel system and method includes a screen grid insulated concrete form panel for use in a wall system. The screen grid insulated concrete form panel includes a filled concrete thermal mass of the wall system located on an interior face of the wall system with expanded polystyrene insulation on an exterior side of the wall system, which results an enhanced thermal stability and isolation of an interior climate of a structure constructed utilizing the wall system.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

Embodiments provide reusable support member capable of facilitating assembly and disassembly of a form, and a concrete placing form. A reusable support member supports outer side surfaces of concrete panels providing cavity as predetermined space for placing concrete includes horizontal rails with a length according to width of the panels, vertical rails with length according to height of the panels, and bolt and nut structures for locking the panels into inner direction of the cavity by penetrating intersections in which respectively parallel the horizontal and vertical rails are combined in lattice shape. Either of the horizontal and vertical rails relating to the intersections, include recesses capable of fitting in opposing rails by receiving a width and a part or all of a thickness of opposing rails. The rails are configured by channel steel or metal material with equivalent shape, and the rails contact the outer side surfaces at equal intervals.

The present invention relates to a method for replacing a conventional mold construction, and includes a plate-shaped outer insulating material, an inner plywood (or a board-shaped finishing material), a connection unit, and a lightweight temporary material. According to the present invention, a wall is constructed by connecting the inner plywood to the lightweight temporary material from a corner foundation surface and by laying bricks. Reinforcement bars are placed after an interior wall is constructed and arranged to cross each other or to alien with each other as instructed in a design specification. Then, an exterior wall is installed corresponding to the connection unit connected to the inner plywood. As a result, a wall having a thermal bridge prevention effect and a higher quality is obtained. Either dry finish or a wet finish is applicable to the wall.

Structural wall with frame in wood, metal, plastic, polycarbonate or other resistant material that has no diagonals or chains strengtheners on its longitudinal axis or, in their absence, its structure is reticulated or articulated. This wall Gets the necessary rigidity through a structuring external to its longitudinal axis by different diagonal elements attached to studs or pillars and slabs, in way to allow a spill or padding to your interior with materials that you they give this wall performance of habitability, such as thermal insulation, acoustic insulation, thermal inertia and resistance the fire, using very cheap fillers as the soil of the place or simple mixtures as the with chaff mud, mud with expanded polystyrene, light concrete, soil with chip wood, soil and volcanic ash, or even the use of industrial waste as chopped tires or other items, some difficult to recycle; In short, you can use a wide range of fillers, depending on the specific need. This way of structuring allows, through the possibility of access at work inside a padded, improving ostensibly simple, fast and economic benefits of habitability of the walls, being easily prefabricate and industrialize, and with a great variety of applications in homes and various types of buildings.

A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other and a cross tie having opposed first and second ends, where at least the first sidewall is a removable sidewall removably secured to the first end of the cross tie. The second sidewall is removably secured to the second end of the cross tie and may be a removable sidewall or a non-removable sidewall. The concrete form also includes a spacer positioned between the first sidewall and the first end of the cross tie. The spacer may be removable along with the first sidewall. Concrete forming assemblies and methods may incorporate concrete forms as described herein.
