A wall structure having an inner wall, a bracket member, a non-combustible board, and an outer cladding coupled together and retaining insulation between the inner wall and the outer cladding. The non-combustible board is positioned between the bracket member and the outer cladding.

A Method and Apparatus for a Fireproof Wall have been disclosed. By utilizing unique and novel thermal resistance and thermal capacitance combinations a fireproof wall can be constructed.

A reduced weight, reduced density gypsum panel that includes high expansion vermiculite with fire resistance capabilities that are at least comparable to (if not better than) commercial fire rated gypsum panels with a much greater gypsum content, weight and density.

A composite fireproof board has a structure that includes, from top to bottom, a bottom layer, a lower reinforcement mesh layer, a middle layer, an upper reinforcement mesh layer, and a surface layer. The middle layer includes an organic frame and an inorganic fireproof material filled within the frame. The frame is provided with fixed grooves on edges adjacent to the fireproof material, and is further provided with through holes.

A building construction system (2) for construction of a building (20) is disclosed. The building construction system (2) comprises a plurality of modules (M.sub.1, M.sub.2, M.sub.3, M.sub.4, M.sub.5, M.sub.6, M.sub.7, M.sub.8, M.sub.9, M.sub.10, M.sub.11), each comprising at least one centrally arranged insulation member (4, 4′) sandwiched between a first cover plate (12, 12′) and a second cover plate (14, 14′). The at least one insulation member (4, 4′) is made in polyurethane (PUR) or polyisocyanurate (PIR). A reinforcement connection structure (10) extends between and is mechanically connected to opposite cover plates (12, 12′, 14, 14′). At least a portion of the joints (6, 6′) between adjacent cover plates (12, 12′, 14, 14′) are glued together.

Described herein are methods for installing field-assembled flooring systems wherein the underlayment is a hybrid design that includes a combination of structural board and cementitious product. The hybrid design is configured to reduce or eliminate the curing time requirement after pouring the cementitious product (e.g., gypsum concrete). The field-assembled flooring systems can reduce or eliminate the chances of the onset of mold due to high moisture levels by removing the cementitious product from the prone areas and replacing it with structural boards. The structural boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere drywall reaches the floor, or the like.

To attain an incombustible sound absorption panel by providing incombustibility to a sound absorption/insulation sandwich panel containing a combustible material as a constituting material.

Fine powder of chips generated during cutting of a foam material to fill in a honeycomb material is located in a gap between the foam material and a sound absorption surface material. A gap between fibers of the sound absorption surface material is blocked by the chips having been moved by a flow such as a water vapor flow generated from hydrate of the honeycomb material heated on the occurrence of a fire. As a result, an air flow path is limited. Further, carbon dioxide gas generated from the foam material is trapped to reduce an oxygen amount, thereby inhibiting combustion. Usage of an adhesive as a combustible material is reduced.

A structural assembly, preferably for creation of a firewall, is constructed using anchors attached to at least a first structure and a concrete wall. Preferably, the concrete wall is also attached to a second structure as well. The body of the anchors is fabricated from a material that fails at a temperature in excess of 1,000° F. A fastening member, preferably a grommet assembly, is positioned in an elongate slot for connecting the first face to the first structure and for sliding engagement within the elongate slot in response to relative movement of the first structure and/or the second structure and the attached concrete wall.

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

Described herein are methods and systems for installing flooring systems that provide waterproofing or water-control capabilities. The flooring systems can utilize a gypsum material or any other self-leveling or concrete material along with a structural board or any other type of cement, wood, gypsum board, compressed board, cellulose fiberboard, sheathing board, or sheet metal material. The flooring systems include a waterproof coating applied to the structural boards to provide the water-control features. The waterproof coating covers seams between structural boards and between structural boards and the subfloor.
