摘要:
A wall comprising a first surface, and a protective coating covering at least a portion of the first surface, where the coating is the dried film of an aqueous composition comprising a first set of polymer particles characterized by having a glass transition temperature that is less than about −40° C., and a second set of polymer particles characterized by having a glass transition temperature in excess of about −25° C.

An earthquake, fire and wind resistant pre-fabricated building panel comprises a plurality of frame members. The frame members are connected together to form a frame lying in a frame plane, the frame defining a perimeter of the panel, the perimeter bounding an interior portion of the panel. At least some of the frame members are biased inwardly, generally in the frame plane, towards the interior portion of the panel. A first solidified castable substance is cast in the interior portion of the frame, between the frame members. A three-dimensional structure such as a house is formed by connecting the panels together. The connections absorb and distribute seismic forces to the entire three-dimensional structure and the biased frame members act to absorb residual seismic forces reaching the individual panels. The castable substance and biased frame members permit the panel to withstand both positive and negative loading and render the panel fire resistant.
摘要:
A face member having opposing edges, formed from a strip of stone tile, a pair of parallel side members each formed from a strip of stone tile, affixed to opposing ones of the opposing edges of the face member, and a base member carrying and supporting the face member and the parallel side members, together forming an edging piece for covering an edge of a stone tile surface construction.
摘要:
An article and process for creating designs on the surface of concrete are provided wherein the flat, flexible article is placed onto and worked into the smooth, wet surface layer of concrete. The concrete is permitted to harden to a partially set condition and the article is lifted from the partially set surface layer of the concrete to leave an impression of the article in the surface layer which becomes a permanent impression when the concrete hardens to a fully set condition.
摘要:
A flexible grid or lattice molding form having a release-layer covered adhesive on one major side surface and a peelable layer on the opposite major side surface. The grid or lattice can be adhered to a preformed wall or flow by the adhesive layer and a cement mixture sprayed on troweled thereover. The upper peelable surface then can be stripped off removing any molding material covering the peelable layer.
摘要:
A decorative relief finished surface is formed by applying to the surface of an object or substrate to be patterned an undercoat of coating material to a predetermined thickness, and forming an uneven pattern having a variety of projections on coated surface a plurality of times with a rolling device having a plurality of convex parts of curved continued, disconnected or perforated line shape which are formed in a random manner, with the intervals between the convex parts being substantially equal to each other, or by spraying coating material with a spray gun so as to form a multiplicity of projections of varying height. Then, the top portions of the projections of the partially hardened surface which extend beyond a predetermined height are pressed with a pressing roll, such that the projections are uniformly flattened to a predetermined thickness while the rest of the convex parts are left unflattened. The pressing roll is made of a hard or semi-hard, air-permeable, porous material.
摘要:
Method and composition for applying a surface covering to a wall or like substrate. The surface covering comprises a flexible strip or sheet of substantially dry, semi-hydrated gypsum, bonded to a re-enforcing mesh or lath. The method includes the steps of coating the rear face of the surface covering sheet with aqueous latex adhesive in an amount which will transfer sufficient water from the adhesive to the gypsum to hydrate and set the gypsum, and, at the same time, invert the latex to a tacky, adherent state; and applying the adhesive-coated surface covering to the substrate.
摘要:
A method of preparing a decorative layer which comprises spraycoating a mortar composition containing 3 - 50 wt% of an epoxy resin and an epoxy hardener, 5 - 70 wt% cement, 5 - 70 wt% of an aggregate powder and 5 - 30 wt% water onto the surface of a base so as to form a concavo-convex surface pattern, pressing the top of the convex portions of the surface while in a semihardened condition to form flat areas on the tops of the convex portions and finish-coating the surface with a synthetic resin enamel or lacquer.
