摘要:
The present invention concerns a process for manufacturing facing panels in composite material (1) which can be applied to structural and not structural walls, to ceilings, to mobile or fixed surfaces, both inner and external of buildings, enclosures or other structures, mainly, but not exclusively, in home-building field or be used as separate and independent walls too. The invention further concerns the panel (1) built through this process. It allows to make decorative, facing and insulating panels (1) whose thickness changes according to the kind of material (3), which basically reproduce any natural materials, such as stone(s) (14), rock(s), marble, wood and not, for example bricks (15) or other finishes with random shapes at variable height differences (5) in plane or curved surfaces, reducing costs and laying time with great flexibility and easy of use.

A method for manufacturing conductive plates, applicable for covering floors or walls, a conductive plate and an injecting machine is provided. The method comprises a) carrying out a polymer concrete mixture or mortar, b) introducing said mortar in a hollow mold with a shape of one of said plates to be obtained when said mortar solidifies, c) making at least one through hole through said mortar deposited in said mold, and d) injecting an electrically conductive ink in said hole, which is at least one in number. A second aspect of the invention relates to a conductive plate manufactured in accordance with the method. A third aspect of the invention relates to an ink injecting machine which can be used to carry out part of the method proposed by the first aspect of the invention.

A method of manufacturing a prefabricated precast riser module, where the required forms that are used in casting the modules are reusable and need not to be transported to the construction site. Each precast riser assembly is finished having brick facings. Brick facings are applied to the vertical surfaces of the precast riser. They are: the commonly used stretcher course and row lock course. A Rebar reinforcing rod is imbedded in the concrete mixture, which will strengthen the assembly to prevent damage when being transported on site. This added strengthening would also allow for minor misalignments during the assembly phase. These novel concrete brick faced modules can be assembled by inexperienced craftsmen, and when completed, will give the appearance of a handcrafted riser that was constructed by professional masonry craftsmen using brick and sandstone.

A decorative aggregate-containing cementitious slurry having decorative aggregate and cementitious matrix composition forms a monolithic structure when effectively applied to a freshly poured cementitious base and simultaneously cured therewith. The slurry and the base are cured for a time sufficient for producing the monolithic structure with a decorative aggregate-containing cementitious surface. The slurry produces a decorative aggregate-containing cementitious layer having a cured thickness effective for permanently securing the decorative aggregate therein with a portion of the decorative aggregate exposed. Various decorative surfaces are produced without requiring expensive hand broadcasting of the decorative aggregate, and without expensive surface grinding. Dry components of the slurry are decorative aggregate and decorative cementitious matrix blend. The blend at least has between about 50% and about 79% blended quartzitic silica, between about 20% and about 35% Portland cement, silica fume up to about 5%, and optionally up to about 8% Class C-like fly ash.

A method of making an article from a lightweight cementitious composition includes molding a castable cementitious mixture including an aqueous slurry of at least perlite and concrete into an article, such as a hollow, decorative article. The castable cementitious mixture can include a fibrous material, for reinforcing the cement and perlite, and an air entraining agent, for facilitating mixability and reducing a density of the cementitious mixture and facilitating casting. The mold can include an external mold form that contains the cementitious mixture and an internal mold form that displaces the cementitious mixture within the external mold form to cast the hollow article in various shapes and with various surface textures. The external and internal mold forms include liners made of a lightweight flexible material that can be removed, unfolded, and prepared and/or cleaned.

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.

An apparatus for supplying particles and/or granules to form a layer of prescribed thickness onto a given surface includes an endless pattern-forming device having a plurality of spaces, a device for supplying particles and/or granules into the spaces via a control member provided on the particle or granule-supplying device, a device for temporarily retaining the supplied particles and/or granules in the spaces and for releasing the temporarily retained particles and/or granules onto the given surface. A patterned shaped article is produced by a method using the apparatus. The method includes supplying dry particles and/or granules for a pattern course into the spaces, temporarily retaining the supplied particles and/or granules in the spaces, releasing the temporarily retained particles and/or granules onto the given surface, and allowing the released particles and/or granules to set on the given surface.
摘要:
A method of carrying out aggregate exposed finish for concrete capable of extremely reducing the usage amount of decorative aggregates, and of facilitating the work without requiring the long working time and the technique of a high level is as follows. The method includes the steps of: loading aggregates on an adhesive sheet; burying part of the aggregates in an adhesive layer of the adhesive sheet; casting mortar or concrete onto an aggregate loading surface of the aggregate loading adhesive sheet; hardening the mortar or concrete; and removing the adhesive sheet.

The invention relates to a formwork element for a formwork system for concrete building purposes, in particular for integration into a construction plane of the formwork system, having a box-like supporting body (1, 2) facing away from the concrete, having an upper side (6) facing the concrete in use, having a recess (3) in the upper side (6) for the fastening of concrete-facing forming means (11; 11′; 35) which can be fastened on/in the recess (3), having a vacuum-permeable spacer (14; 17) having a plurality of passage openings (16), and having connection devices (7, 8, 9) for applying a vacuum, wherein a plurality of forming means (35) can be reversibly fastened by means of vacuum at the top side (6). The invention also relates to a formwork system having such a formwork element and a concrete component which has been created with the formwork element or the formwork system.
