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.

A stay-in-place form comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.

A building formwork module for use in a modular formwork system, the module comprising a first wall spaced away from a second wall, the first and second walls being connected by at least one web extending between the first and second walls, the first and second walls and said at least one web defining a channel extending over at least a part of a longitudinal length of the module, the channel adapted to accommodate fill material during use, the web further comprising at least two apertures spaced apart across the web in between the first and second walls such that during use one or more transverse reinforcing members can be positioned in between reinforcing members received in the spaced apart apertures thereby limiting movement of the transverse reinforcing member there-between during use.

Disclosed herein is a system 100 for constructing an insulated thermal mass concrete structure comprising four or more walls 100a, 100b, 100c, 100d. The system 100 comprises interconnected frame members 30, 30, 30, 30, 30*, cross-ties 40 and corner members 33, 33, which reduces the need for props or stays to support the walls 100a, 100b, 100c, 100d during curing of a concrete core poured between inner and outer layers, 20, 21, 22, 23, 25 attached to the frame members 30, 30, 30, 30, 30*.

A system and method for constructing an insulated concrete form (ICF) wall are provided. Vertically-oriented pairs of ICF foam panels of an ICF structure are erected above a footing, with vertical panel supports located along opposed vertical edges of each set of adjacent vertically-oriented panel pairs. An internal brace support, extending longitudinally along the structure, is installed between the individual panels of the panel pairs. Concrete is poured between the erected vertically-oriented ICF foam panels to complete the ICF wall.

A stay-in-place lining is provided for lining a structure fabricated from concrete. The lining comprises a plurality of panels connectable via complementary connector components on their longitudinal edges. Each panel comprises a first connector component on a first longitudinal edge thereof and a second (complementary) connector component on a second longitudinal edge thereof. The lining comprises at least one edge-to-edge connection between the first connector component of a first panel and the second connector component of a second panel, the edge-to-edge connection comprising a protrusion of the first panel extended into a receptacle of the second panel through a receptacle opening. The receptacle is shaped to prevent removal of the protrusion from the receptacle and the receptacle is resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the edge-to-edge connection.

A modular structural system, comprising one or more building units consisting of two counter mold partitions, each of which is adapted with one or more anchoring means, into which one or more connecting locks are engaged to firmly lock and stabilize the two counter mold partitions, where each of the two counter mold partitions is peripherally adapted to receive one or more affixing coupling means; two or more coupling means for affixing two of the one or more building units; two or more coupling means for affixing the one or more building units to an adjacent building element.

Various cement-containing forms and related compositions and methods are disclosed herein. Some cement-containing forms disclosed in this application include cement and expanded polystyrene. The cement forms, in some cases, are formed by a process that involves combining cement and expanded polystyrene with one or more liquids that interact with the expanded polystyrene to improve adhesion between the cement and the expanded polystyrene. The resulting forms may provide insulating properties. Some of the disclosed cement-containing forms and compositions may also have a relatively low density in comparison with other cement-containing compositions.

Prefabricated panel formwork, suitable for being used in the construction of buildings and gardens. Pre-fabricated panel formwork provided with a pair of vertical metal sections to which a back metal wall and a front metal wall are fixed, being suitable to define an intermediate cavity that is open on top and on the bottom; wherein at least said front metal wall is provided with a plurality of horizontal slots, each of them being positioned at the top of an underneath pocket that protrudes frontally from the same wall.

A stay-in-place form comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.
