Described herein is a flame-retardant building panel comprising a body having a first major surface opposite a second major surface, an inorganic coating atop the first major surface, the inorganic coating being optically transparent and flame retardant and comprising a silicate compound; and wherein the inorganic flame retardant coating is substantially transparent such that the first major surface of the body is visible through the inorganic coating.

The present invention provides an anchor assembly for attaching a first structure to a second structure. The anchor assembly has a body having a first face and a second face. The first face is transverse to the second face and has an elongate slot. The second face has a through hole. The body is fabricated from a material that fails at a temperature in excess of 1,000° F. A fastening member is positioned in the elongate slot for connecting the first face to the first structure and for sliding engagement with the elongate slot in response to relative movement of the first structure and the second structure.

A multi-level parking garage constructed to be in close proximity to an adjacent building includes two or more levels above ground. Each of the two or more levels has a floor and a ceiling. The multi-level parking garage includes a load-bearing support structure for supporting the two or more levels and a plurality of fire-rated, non-load bearing exterior wall panels. Each of the exterior wall panels are independently and removably mounted to the support structure around at least a portion of a periphery of each of the two or more levels such that the plurality of exterior wall panels extend from the floor of each of the two or more levels to the ceiling of each of the two or more levels.

Disclosed are a fireproof material, a fireproof plate, a fireproof wall structure for tunnels and a construction method. The fireproof material includes the following components in weight ratio: 20-35 parts of aluminosilicate; 10-25 parts of calcium carbonate; 5-15 parts of magnesium oxide; 5-15 parts of silica; 20-40 parts of a binder; and 5-10 parts of a curing agent, the binder includes at least one of lithium silicate, potassium silicate and sodium silicate in combination with at least one of quartz sand and industrial sugar; and the curing agent is at least one of lithium oxide and magnesium oxide. In the preparation, firstly forming the mixture of aluminosilicate, magnesium oxide and silica into particles at 900° C.-1250° C., and then mixing the particles with calcium carbonate, the binder and the curing agent, and then pouring same into a forming mold and heating and pressing to form the fireproof material.

Described herein is a barrier coating composition comprising an organic blend comprising a first component and a second component, the first component comprising latex polymer and the second component being selected from polyurethane emulsion, wax emulsion, and alkyd emulsion, wherein the first component and the second component are present in a weight ratio ranging from about 2:1 to about 20:1, and the latex polymer has a glass transition temperature of less than about 18° C.

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 sheet rock reaches the floor, or the like.

Disclosed herein is a thermal and/or fire resistant panel comprising: a panel body comprising a fire resistant composition, wherein the fire resistant composition comprises: a silane cross-linked hybrid inorganic polymer; and a siloxane.

The invention comprises a fire retardant board comprising a core formed from flute paper, wherein the flute paper is pre-impregnated with a flame retardant. The core is formed as a three dimensional body presenting a first face and a second face opposed to said first face and a wall structure which defines a plurality of channels intersecting the first face at an angle (a) which is 90 degrees or less than 90 degrees. The board further comprises a first liner attached to the first face and an adhesive arranged to fix the first liner to the first face of the core. The invention further comprises a method for manufacturing a fire retardant board comprising the steps of providing a core formed from flute paper, which is pre-impregnated with a flame retardant, applying an adhesive to the first face of the core, and laminating a first liner to the first face of the board.

A barrier and method of manufacture thereof is provided. The barrier is suitable for enhancing the reaction to fire of structural elements such as construction boards.
