A reinforcing framework (10) for the construction of reinforced concrete structures includes at least two spaced-apart mesh layers (202, 204). A plurality of spaced-apart spacers (206) are mounted between the mesh layers (202, 204) to support the two mesh layers (202, 204) spaced-apart in substantially parallel planes. Each spacer (206) has a cross member with a leg extending outwardly at each end of the cross member, said legs being substantially parallel to each other and substantially perpendicular to the cross member. Each leg has a foot at an outer end of the leg remote from the cross member, the foot being substantially perpendicular to the leg and substantially perpendicular to the cross member. The cross member is bent inwardly between the legs.

This invention refers to a weight-lightening disc for making light reinforced concrete structures such as slabs, prefabricated slabs, foundation slabs, partition walls and beams; to a mesh, specifically designed for this invention and to the construction method to make such structures. The method allows manufacturing the components that make it possible to construct buildings with light reinforced concrete structures. The field of application of the invention is construction in general, such as houses, buildings and bridges. The invention provides a solution to the problem of lightening of the structures, including a construction method that comprises a set of weight-lightening discs in combination with electro-welded meshes (specially designed for the each specific thickness of the slab) and the hooks that hold together the meshes. The compound of elements and the method allow lightening minimum-thickness slabs.

A reinforcing element includes a first and a second reinforcing mat having metal mat rods, which are welded at angles to each other at junction points, which reinforcing mats are held spaced apart from each other at a normal distance by rod-shaped spacers with respect to the first mat plane and the second mat plane of the reinforcing mats. The spacers are metal and are permanently connected to individual mat rods of the first and second reinforcing mat by welding connections, preferably resistance welding connections, wherein at least individual spacers protrude outward at least beyond the first mat plane of the first reinforcing mat in a direction pointing away from the second reinforcing mat by a first protrusion length. Further, a double wall is furnished with the reinforcing element and a method produces the reinforcing element and the double wall.

A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

A thermally broken truss (10) for a cage of a structural building panel, comprising: first and second elongate outer support members (12, 14); first and second elongate intermediate support members (16, 18) interposed between the first and second outer support members (12, 14); at least one first connecting member (20) interconnecting the first outer support member (12) and the first intermediate support member (16); at least one second connecting member (22) interconnecting the second outer support member (14) and the second intermediate support member (18); and a thermally insulative fastener (24) which fastens the first and second intermediate support members (16, 18) together in spaced apart relationship, thereby providing a thermal break between the first and second outer support members (12, 4). A thermally broken structural building panel (40) is also provided.

A prefabricated modular reinforced concrete building system includes panel assemblies for foundations, walls, decks, and roofs designed to be built out in a manufacturing facility, shipped to a job site, and filled with concrete. Panel assemblies incorporate a space frame to ensure structural integrity during shipping and during concrete fill. Space frames can include structural columns, rebar mats, spacers, straps, and skin panels. Panel assemblies may be manufactured to contain architectural interior/external finishes, windows/doors, and pre-installed utility distribution systems.

A reinforced concrete composite beam structure based on precast concrete beam-slab integrated units include rib beams and rebar cages; stirrups in the rib beams are closed stirrups; upper parts of the closed stirrups in each rib beam are extended from the rib beam and taken as connecting rings; the rebar cages are disposed on upper parts of two connected rib beams; the connecting rings are lapped with beam surface closed stirrups to form the reinforced concrete composite beam structure with the rib beams after casting concrete. Its construction method includes: installing the precast concrete beam-slab integrated units; hoisting the rebar cages on the rib beams to tie two corresponding connecting rings with the corresponding beam surface closed stirrup in a staggered and overlapped manner; and casting concrete to submerge the rebar cages. A form of the closed stirrups is proposed when rib width of the rib beams is small.

The present invention relates to a prefabricated deck unit for a building system, the deck unit including: a reinforcing framework encased in a composite material, the reinforcing framework comprising: a first metal mesh unit, a plurality of interspaced spheroidal void formers attached to or in intimate contact with the first mesh unit, and a second mesh unit resting upon, or attached to, the spheroidal void formers, wherein the framework defines at least one terminal channel on at least one end of the deck unit, the terminal channel being shaped and dimensioned to snugly receive an elongate connecting rod for connecting the deck unit to a further structural element of the building system.

A first lock formed on the first end portion configured for attachment by torsion to a first reinforcement wire mesh cage of the two reinforcement wire mesh cages with a first spacer cover extending from the first lock away from the intermediate portion. A second lock formed on the second end portion comprising the same to hold two reinforcement wire mesh cages a fixed distance apart from each other with the first spacer cover and the second spacer cover being less than a distance between respective reinforcement cages and spaced apart inner surface of the form.

Embodiments of the present invention relate to a prefabricated structural beam unit for a building structure. The beam unit includes a planar sole, two laterally spaced, elongate sidewall sections, and two longitudinally spaced endwall sections. The sole, sidewall sections and endwall sections combine to define a cuboid cavity at least partially filled with a composite material, wherein at least one endwall section includes one or more structural engagement connectors dimensioned to engage with, or interlock, under gravity assistance with one or more complementary structural engagement connectors forming part of a further prefabricated building unit of the building structure.
