The invention relates to a system for erecting a building structure, the system comprising a foundation for receiving the building structure, and a plurality of inner and outer walls, roof and floor panels, the panels being adapted to engage each other for defining at least one story of the building structure, wherein the foundation comprises a first section and a second section, the first section being adapted to bear the load of the building structure and the second section being adapted to provide access to the interiors of the building structure.

A concrete dowel slip tube assembly is provided for use in maintaining a planner consistency of a cured concrete slab formed on a support surface. The assembly comprises a plurality of elongate slip tubes, each having a length dimension and a tubular hollow interior compartment. Dowels are slidingly engageable to the hollow interior compartment to allow for translation along the interior compartment. A support frame defines a plurality of integral slip tube retaining members, disposed at evenly spaced locations along the support frame, the retaining members being configured to receive and engage associated slip tubes to the support frame in a common defined orientation. The support frame and the retaining members are formed as a unitary construction.

A slab bolster element includes a frame member having a male connector at a first end and a female connector at an opposite second end. The male connector includes a substantially solid insertion body with a surface having a transverse locking groove. The female connector includes a receptacle body configured to receive the insertion body of a complementary male connector, and a resiliently flexible locking tab positioned and configured to resiliently deflect to allow the insertion of the insertion body of another slab bolster element into the receptacle body, and to resiliently engage with the transverse locking groove of the insertion body when the insertion body is received within the receptacle body.

A module for constructing foundations for a structure, comprising: a plurality of formwork members that define a pair of side walls that define a space between the side walls; thereto to hold the side walls in a spaced relationship; a three dimensional reinforcement cage that includes the brace, a plurality of first members, and a plurality of second members perpendicular to the first members, the first members coupled to at least the brace and the second members coupled to at least one of the plurality of the first members and the brace, wherein the cage forms an internal support within the space between the side walls for receiving a settable material, such that the side walls become integrated with the internal support as the settable substrate sets, to form the module.

A system for assembling a transpiring, disposable heat-insulation shuttering mould and/or formwork used to cast a concrete surface, which includes at least one supporting plane featuring one upper surface on which a plurality of supports are arranged, which are suited to accommodate and retain (at least sideways inside themselves) at least one longitudinal or reticular portion of a tubular element.

An adjustable concrete form brace includes a horizontal adaptable extension member. A first lower brace element and a second lower brace element opposing the first lower brace element each have a horizontal insertion channel adapted to receive the horizontal extension member. A first upper brace element and second upper brace element are attached to the first lower brace element and the second lower brace element respectively. Each of the lower brace members include a saddle, and each saddle is adapted to retain one or more reinforcement bars. The first upper brace element and second upper brace element each include a form retaining element.

A post anchor is provided for securing a post within a poured concrete slab. The post anchor comprises a socket having a first cavity sized to receive the post therein. A jacket member is adapted to mount over at least a portion of the socket. At least one tensile member is mounted to, and extending from, the jacket member. The jacket and tensile members function to reinforce the socket and to distribute any forces exerted upon the post anchor further into the surrounding concrete. The socket may be provided in a variety of heights, to allow the post anchor to be easily adapted to a variety of slab depths.
