摘要:
An object of the present invention is to provide a sound insulating sheet member that has high sound-insulating performance which exceeds mass law while being relatively light weight, that is highly flexible in design, excellent in versatility, and easy to manufacture so that productivity and economic efficiency can be improved, and a sound insulating structural body or the like using the same. The object thereof is achieved by using a sound insulating sheet member comprising at least a sheet having rubber elasticity and a plurality of resonant portions, wherein the resonant portions are provided in contact with a sheet surface of the sheet, each of the resonant portions including a base part and a weight part, and the weight part being supported by the base part and having a larger mass than the base part.

The invention relates to a fire resistant wall structure (1), comprising a first wall element (2) and a second wall element (3). Both wall elements comprise a surface plate (4), which is provided at its first edge (41) and at its second edge (42) opposite to the first edge with bends for joining the wall elements to each other. In order to provide a light and robust structure, the first wall element has its first edge (41) provided with a first set of bends (10') having a first bend (51') which is fashioned at a right angle relative to the surface plate and from which is established a second bend (52') which is in parallel direction with the surface plate and from which is established a third bend (53') made at a right angle against the surface plate for constructing a closed box type structure. The second wall element has its second edge (42) provided with a first bend (61') which is fashioned at a right angle relative to the surface plate and from which is established a second bend (62') in parallel direction with the surface plate for constructing an open recess at an edge of the wall element. In order to secure the wall elements to each other, the first set of bends having a closed box type structure is adapted to be fitted to the second set of bends which establishes an open recess.

A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.

Example flexible wall panels (e.g., demising walls) comprising a flexible, thermally insulated multilayer panel with a flammable core has a surprisingly low flame-spread index and smoke-developed index due to the flammable core being sandwiched between two fire resistant pads. The flammable core's high thermal resistance (high R-value) provides most of the panel's thermal insulation while a peripheral compressed region and the fire resistant pads help keep the flammable core from burning. In some examples, the materials and thicknesses of the panel's core, fire resistant pads and surrounding outer skin are such that the panel is of sufficient flexibility to be folded onto itself without experiencing appreciable permanent damage.

Die Erfindung betrifft ein Wärmedämmverbundsystem mit einer auf einer Außenseite einer Gebäudeaußenwand angebrachten ein- oder mehrlagigen Wärmedämmschicht und einer hierauf aufgebrachten ein- oder mehrlagigen Putzschicht, wobei die Wärmedämmschicht wenigstens eine Wärmedämmplatte aus einem Hartschaum, insbesondere aus einem Polystyrol-Hartschaum, sowie wenigstens ein platten- oder profilförmiges Wärmedämmelement zur Ausbildung einer Brandbarriere umfasst. Erfindungsgemäß umfasst das die Brandbarriere ausbildende, platten- oder profilförmige Wärmedämmelement einen Wärmedämmstoff, welcher Aerogel-Partikel und wenigstens ein wasserbasiertes organisches und/oder anorganisches Bindemittel enthält und eine Wärmeleitfähigkeit ≤ 0,028 W/(mK), vorzugsweise ≤ 0,025W/(mK), weiterhin vorzugsweise ≤ 0,022 W/(mK), besitzt. Ferner betrifft die Erfindung ein als Brandbarriere in einem Wärmedämmverbundsystem einsetzbares, platten- oder profilförmiges Wärmedämmelement sowie die Verwendung eines solchen platten- oder profilförmigen Wärmedämmelementes als Brandbarriere.
