Abstract:
A system (14) for delivering mortar (16) to blocks or bricks (12) used for receiving and dispensing the mortar (16) at an elevated pressure. A delivery hose (58) is attached to the tank (32). A nozzle (26) having an inlet (28) and an outlet (30) is used for delivery of the mortar (16). The inlet (28) of the nozzle is in fluid communication with the delivery hose (58). The mortar (16) is discharged as a single stream or bead of mortar (24) from the outlet (30) of the nozzle (26) onto the block or brick (12) used for forming the wall (10). The single stream of mortar (24) is placed on the ends and opposite edges of the side face of the block (12). Each block (12) is placed end to end next to each other forming a first course of blocks (12). The wall (10) continues upwardly as blocks (12) are positioned over the streams of mortar (24) placed on the sides of each course of blocks (12). The position of the streams of mortar (24) on the blocks can be controlled by an index guide (68) that is mounted on the nozzle (26). The index guide (68) is used to engage the side of a removable wall panel, fixed wall panel or existing wall structure (66).
Abstract:
A Mortal' Delivery System Is described. The Mortar Delivery System provides precise control of the delivery and application, of mortar in addition to the mixing and tempering of mortar. Such control eliminates the use of a hand trowel in brick, block and stone laying applications. Sensing and control are integrated with the Mortar Delivery System to make it an important element of a robotic brick laying system. The Mortar Delivery System contains sensors to measure mortar viscosity and workability, mortar flow rate, and mortar nozzle pressure. The data from the Mortar Delivery System sensors can be used to change the rotational speed of the shear blades, change the amount of water being used for mixing or tempering, and change the delivery speed of the mortar. Such changes result, in precise control of mortar that is in turn suitable for automated or semi-automated building processes.
Abstract:
A method of forming a structural wall (10) using lightweight or heavyweight block or brick (12). A removable lightweight wall panel (16) is used as a guide for forming the wall (10). The method includes installing the removable panel (16) on a foundation (14). The wall panel (16) is plumbed vertically and leveled horizontally. A bonding agent (33) is placed on the bottom and at one end of each block (12) and the blocks are placed in courses to form the wall (10).
Abstract:
The invention concerns a device for coating building surfaces (1) with curable viscous materials (6). The device comprises a connection piece for delivering viscous material, a nozzle arrangement (2) for applying viscous material, and a smoothing limb (3) for smoothing the surface of a layer once applied. In order to simplify and rationalise the application process and prevent the defects caused by the jet delivery, the application device is designed in such a way that the nozzle arrangement consists of a flat nozzle (2, 7) whose outlet aperture (20) is open towards the building surface (1) and counter to the direction of application (A) in the plane of the applied layer (61, 62, 63, 64), and the smoothing limb (3) of the outlet aperture (20) is immediately adjacent to the flat nozzle (2), extends away from the direction of application (A) and lies tangentially to the applied layer (61, 62, 63, 64). The invention also concerns a method of producing certain objects and elements for buildings and the like using the proposed device.
Abstract:
A stackable building block (1102) for constructing a masonry wall includes a front section having an outer surface, an inner surface, a bottom surface, and a top surface (1109). The top surface (1109) includes one or more regions (1500 and 1502) having a higher surface height that is manufactured and then precision ground to the desired height and positioned between or next to lower surface areas (1113). The building block (1102) also has a rear section substantially parallel to the front section and similarly arranged. The top surface may include a tapered region beginning proximate at least one of the side or end regions and tapering outwardly away from the side toward the center of the block. The tapered region may include an indentation. The tapered region and indentation provide a true mortar joint capability and resistance to water infiltrating the joint. During assembly of the stack building block, a thin set mortar, grout or adhesive is used between successive courses and that is applied using a high speed applicator.
Abstract:
A portable gap filling machine (1), of the type normally used in the field of building, which comprises a container (7) for the building mix to be dispensed (8), a dispensing tip (9) and, interposed between them on a connecting duct (6), a unit for pumping the mix. The pumping unit comprises a peristaltic pump (5), which is driven by an autonomously powered motor drive; the pumping unit is compact and lightweight.
Abstract:
The present invention relates to a method and an apparatus for distributing mortar or the like binding material mix in connection with masonry work. Said binding material mix is held in a hopper (1) suspended above the workplace. From the hopper said mix is first induced by forced action conveyor means (2, 3) to move in a controlled manner essentially horizontally to above a distribution point. The mix is thereafter induced to flow, via distribution means comprising a flexible free fall portion (10, 10a) and material mix spreading means (11) arranged at said distribution means, down to the final destination (17) of the work.
