摘要:
An insulated concrete panel comprising an insulation layer having one or more openings extending therethrough, a first concrete layer adjacent to a first surface of the insulation layer, a second concrete layer adjacent to a second surface of the insulation layer, and a wall tie received within one or more of the openings. The wall tie includes a central section received within the one or more openings of the insulation layer, a first concrete engaging at least partially embedded within the first concrete layer, and a second concrete engaging section embedded within the second concrete layer. The second concrete engaging section has a maximum width that is larger than a maximum width of the central section. The central section of the wall tie is configured to transfer shear forces and resist delamination forces between the first and second concrete layers.

A shear connector for use with insulated concrete panels. The shear connector comprises an elongated core member that includes a first end and a second end, and a flanged end-piece removably secured to one of the first end or the second end of the core member. At least a portion of the flanged end-piece includes a maximum diameter that is larger than a maximum diameter of the core member. The shear connector is configured to transfer shear forces.

摘要:
A fabricated concrete foundation wall is provided with a plurality of insulation panels and reinforcing ribs to improve strength and reduce the density of the wall panel. The foundation wall panels are easily placed and interconnected together to quickly provide a foundation adapted to support the main walls of a home, for example. The foundation panels in one embodiment generally include a facewall that may have at least one carbon fiber band positioned horizontally therethrough to provide additional stiffness.

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 structural element (10) for use as a ceiling element or wall element. The structural element (10) has a facing shell (11) and a relatively thicker supporting shell (12). The facing shell (11) has a first concrete layer (14) with a textile reinforcement (15) arranged therein. The supporting shell (12) has a second concrete layer (16) and a supporting shell reinforcement (17) in the form of a box-grid structure from interconnected structural steel elements (18, 19, 20). The facing shell (11) is connected to the supporting shell (12) by a plurality of metal-free connecting bodies (24)in the form of a three-dimensional a textile grid structure (25). The textile grid structure can be produced as a woven fabric, a plait, a nonwoven fabric or a knit from carbon fibres and/or glass fibre threads that have a coating to produce the three-dimensional structure. Each connecting body (24) extends in at least two spatial planes.

A lightweight cementitious composition containing from 22 to 90 volume percent of a cement composition and from 10 to 78 volume percent of particles having an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.03 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3, where after the lightweight cementitious composition is set it has a compressive strength of at least 1700 psi as tested according to ASTM C39. The cementitious composition can be used to make concrete masonry units, construction panels, road beds and other articles and can be included as a layer on wall panels and floor panels and can be used in insulated concrete forms. Aspects of the lightweight cementitious composition can be used to make lightweight structural units.

An insulative, lightweight concrete building panel is provided with one or more fiber or steel reinforcements which are manufactured in a controlled environment and can be easily transported and erected at a building site.
摘要:
A structural panel, including a plurality of contiguous elongated filler members mutually contiguous ones of the filler members having opposed surfaces pressed against one another in vapor tight face-to-face contact with each other and having opposite side surfaces extending from the opposed surfaces, a three-dimensional supporting matrix, including a plurality of lattice structures, each being interposed between and pressed into adjacent surfaces of the members, each of the lattice structures having opposite side portions projecting slightly beyond the opposite side surfaces of the members, and a mesh of wire, in the form of lateral and longitudinal wires attached together at their right angle intersections extending across the filler members, the members being fixed to the projecting opposite side portions of the lattice structures by C-clips to thereby hold the lattice structures and filler members pressed together in a unitary panel configuration.
摘要:
A method of fabricating a composite structure comprising wire mesh and concrete. The longitudinal wires of a section of such wire mesh are formed together into a repeating sinuous pattern perpendicular to the transverse wires, so that the alternate transverse wires together comprise two groups each in one of two parallel spaced apart planes. A flat section of similar mesh is placed against each of these groups. Each of the flat sections of mesh and the juxtaposed group of transverse wires of the formed mesh are in turn placed together to be cured, into first and second layers of wet concrete mixes in suitable forms to produce the composite concrete-steel network structure. The relatively light weight structure may be utilized for floor, ceiling or roof slabs, and for column load bearing wall panels. According to other aspects of the invention, the mesh sections and the concrete layers may also be curved transversely or longitudinally, so as to comprise composite arcuate panels for tanks or other curved structures. The space between the concrete layers may carry circulation barriers or insulation material to increase the insulating properties of the structure.
