Abstract:
A shear panel for constructing underlayments for floors and roofs of buildings includes a first rectangular layer of fire-resistant material, such as cementitious board, bonded to a second rectangular layer of thin high-strength material, such as galvanized steel. The length of the second layer is longer than the length of the first layer. The additional length of the second layer forms a tab extending from one end of the panel. During construction, a first panel is attached to a set of beams (floor joists or roof rafters) with the tab spanning between adjacent beams. A second panel is positioned on the beams with at least a portion of the second panel overlapping the tab of the first panel. The overlapping portion of the second panel is fastened to the tab of the first panel to form a continuous shear diaphragm for the floor or roof.
Abstract:
A roof cover board made from a mixture of 30-60% stucco; 20-50% perlite; 10-30% cellulose fiber; 3-20% starch; and siloxane. Also disclosed is a stucco-free roof cover board made from a mixture of 30-60% perlite, 30-60% cellulose fiber, 5-25% starch; and siloxane. Also disclosed are methods for making same.

Abstract:
The invention relates to building construction and is used for building sloping roofs of different-purpose buildings. The inventive roofing system consists of roof tiles, horizontal parallel base blocks and fittings. The visible external surfaces of the roof tiles are embodied in several variants which are united by a multipurpose locking device provided with similar configuration and connection dimensions, thereby making it possible to assembly diversified roofing patterns. Each tile is provided with fixing holes embodied in the top and side parts thereof and a tingle embodied in the middle part of the wedge flange of a shape-generating tile edge. The position of the fixing holes is selected in such a way that the holes of each previous row coincide with holes of each successive row of the roofing. The roof tile fixation is embodied in such a way that it is not visible and mounted on wooden or metal perforated blocks. The roof tiles are assembled on said perforated metal blocks in a constructor manner. Said invention makes it possible to improve the roofing quality and reliability and eases the roof tile mounting for forming a roof.
Abstract:
Изобретение относится к области строительства и предназначено для создания скатных кровельных покрытий зданий различного назначения. Кровельная система состоит из черепиц, горизонтальных параллельных брусков основания и крепежных элементов. Черепицы имеют несколько вариантов выполнения внешней видимой поверхности, которые объединяет универсальное замковое устройство с одинаковой конфигурацией и присоединительными размерами. Это дает возможность собирать разнообразные рисунки кровельного покрытия. В каждой черепице выполнены крепежные отверстия в ее верхней и боковых частях и отверстие под кляммер в средней части клиновидного ребра формообразующей кромки черепицы. Местоположение крепежных отверстий выбирается таким образом, чтобы гарантировать совпадение этих отверстий в каждом последующем ряду кровельного покрытия с отверстиями в каждом предыдущем ряду покрытия. Крепление черепицы скрытое и выполняется на деревянные или металлические перфорированные бруски. Укладка черепиц на перфорированные металлические бруски производится по принципу конструктора. Изобретение позволяет также повысить качество и надежность кровельного покрытия, упрощает монтаж черепиц при формировании кровли
Abstract:
A reinforced concrete tile is provided with substantially increased tensile strength and lightness in weight by a lightweight substrate layer of reinforced resinous material which has been applied while wet to the lower surface of layer of concrete so as to integrally bond itself to the layer of concrete. The substrate layer may comprise a resinous mixture reinforced with fibres or with a mesh of fibreglass or other appropriate composition. In a first method of making reinforced concrete tiles, a concrete tile which has been formed has the bottom surface thereof treated so as to roughen the surface and remove any loose debris therefrom. A layer of reinforced resinous material is then applied to the bottom surface of the concrete tile. In a second method of making a reinforced concrete tile, wet concrete is extruded onto a pallet having an upper surface, which may be formed by a liner of appropriate configuration to impart a wood shingle appearance, and which defines the top surface of a tile to be formed. After shaping the wet concrete tile on the pallet, a layer of reinforced resinous material is applied to the surface of the wet concrete tile opposite the pallet, so as to form a reinforced substrate layer on the base of the concrete tile being formed, before curing and removing the tile. The layer of reinforced resinous material may be applied by application of layers of resinous slurry before and after application of a layer of mesh, or by pressing the mesh onto a layer of slurry using a roller. The layer of mesh can be offset to form the base of a moulded sidelock portion of the tile and to help secure the tile to an underlying roof structure. In accordance with still further methods, reinforced tiles are formed by disposing a layer of mesh between concrete layers of different thickness and by placing a layer of mesh on the upstanding pegs of a pallet and forming the concrete tile thereover.
