Abstract:
A render layer for a building comprises a honeycomb core of nonwoven polypropylene web, and a cementitious material fully filling the cells of the core, wherein (i) the nonwoven web has a porosity of from 5 microns to 600 microns, (ii) the core has a cell size of from 5 mm to 200 mm, (iii) the expansion and contraction across the plane of the core is greater than the expansion and contraction of the cementitious material filling the cells of the core, and (iv) the cementitious material is partly impregnated into the cell walls of the core.
Abstract:
Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.
Abstract:
The present invention includes a material and method of installing a construction material for dry or arid climates, comprising: a growth media comprising an abiotic porous material and activated charcoal such as biochar; and at least one of a compost, grain hulls and nut shells, wherein plants in the material are able to survive without exogenous water for use in areas comprising at least one of Aw, BS, BW, Csa, Csb, Ds or Dw climates according to the Koppen-Geiger climate classification.
Abstract:
Non-woven fabric having an inner side and an outer side, wherein the inner side of the non-woven fabric has a surface roughness Ra of from 25 to 60 micrometers, preferably from 25 to 50 micrometers, advantageously from 25 to 40 micrometers.
Abstract:
The present invention relates to a laced composite system with high rotational capacity and ductility which resists the suddenly applied dynamic loads by undergoing excessive plastic deformation, while still maintaining the integrity of the system. The laced composite system comprising, a sandwiched filler material between upper and lower cover plates (1); the said cover plates being provided with the plurality of perforations (2) along the length, plurality of reinforcing members (3) being passed through the said perforations to connect the said cover plates leaving bent edges of the reinforcing members projecting outside the cover plates, plurality of transverse/cross rods (4) being attached at the outer side of the said cover plates through the space available in between the cover plates and bends of the reinforcing members projecting outside the cover plates to hold the said reinforcing members in order to enhance the ductility and rotational capacity of the said laced composite system. This invention has been particularly developed for resisting suddenly applied dynamic loads such as blast, impact, etc.
Abstract:
A panel comprising one or more decking members is arranged such that a settable material can be supported thereon to form a composite panel. The panel further comprises one or more elongate strengthening elements, each element being arranged to connect to the one or more decking members in a manner such that the one or more elements increase panel strength.
Abstract:
Embodiments of the present invention provide a sandwich composite panel assembly including a first face plate having an inside and an outside surface; two or more first shear connectors coupled to said inside surface of said first face plate; a second face plate having an inside and an outside surface; and two or more second shear connectors coupled to said inside surface of said second face plate; wherein, when said panel is assembled, said first and second face plates define a cavity for receiving a filler material and each of said first shear connectors is coupled to a corresponding one of said second shear connectors within said cavity. The shear connectors may have a variety of different shapes and sizes.
Abstract:
A metal frame defined by sides of cold formed steel channel section defines an open space. The space is covered by a mesh and a breathable membrane and a layer of self-setting self levelling composition is applied and allowed to set to form a wall panel for the inside of a room.
Abstract:
A lightweight cementitious panel/tile is provided with increased bending stiffness and less weight than conventional construction panels. The cementitious panel is constructed of a cementitious surface (which may be reinforced with wood fiber or other materials) supported by an integrated stiffener grid on the underside to absorb stresses and loads.
