A first highest point of the case at the side of the non-contact surface is not higher than a second highest point of upper ends of the plurality of the ribs. | 12-05-2013 |
| 20140308381 | CONTOUR CRAFTING EXTRUSION NOZZLES - An automated extrusion construction system may include an extrusion nozzle configured to extrude construction material in a substantially horizontal direction against an elongated and substantially vertical surface. An extrusion nozzle may have a height adjustment mechanism configured to adjust the height of an outlet in response to level deviations in the surface on which the construction material is extruded by the extrusion nozzle. An automated extrusion construction system may include a slicing mechanism configured to controllably slice through the extruded layer. | 10-16-2014 |
| 20150030712 | PORTABLE ROBOTIC CASTING OF VOLUMETRIC MODULAR BUILDING COMPONENTS - A robotic casting machine (RCM) provides for on-site, or near-site casting and automated production of cast components, such as concrete modular, volumetric building components. The RCM includes stationary and mobile support structures, which can be positioned in a loading configuration, a casting configuration and an ejection configuration in which the cast volumetric component may be ejected from the mold. Tipping machines located beneath the cast component facilitate ejection, rotation and loading of the ejected module onto a transport surface for transport of the module. The support structures are constructed of prefabricated frames that may include at least one standardized section, which may be utilized on every project, and may also include a customized section, which may be provided to achieve desired dimensions of the cast module on a particular project. A casting process is provided in which a volumetric module is cast in a rotated orientation, in which the floor is cast with an initial vertical orientation, the transverse walls extend in a horizontal orientation, which is cast in vertical wall forms, and a longitudinal wall extends horizontally along the top of the mold. Modular, volumetric components created using the RCM and casting process are also described. | 01-29-2015 |
| 20150300036 | AUTOMATED CONSTRUCTION OF TOWERS AND COLUMNS - A robot may extrude a tower or column. The robot may include an extrusion nozzle, a positioning system, a climbing apparatus, and a controller. The extrusion nozzle may controllably extrude uncured construction material. The positioning system may controllably cause the extrusion nozzle to traverse a perimeter layer of the tower or column. A climbing apparatus may controllably cause the robot to climb. A controller may autonomously: direct the positioning system to cause the nozzle to traverse the perimeter layer of the tower or column; direct the nozzle to extrude uncured construction material during the traverse; direct the climbing apparatus to cause the robot to climb an incremental amount; and repeat each of the foregoing positioning, extrusion, and climbing steps until the extruded tower or column attains a desired height. | 10-22-2015 |
| 20160115659 | CART FOR BUILDING A BRIDGE BOARD FORWARD PROGRESSIVE - Cart for building a bridge board forward progressive which incorporates a system for positioning reinforcement pieces, which have displacement tracks on the upper working surface and runners on which the reinforcement pieces are situated and which are displaced on the displacement tracks, where by means of the system for positioning reinforcement pieces it situates the reinforcement pieces in a position of the upper working surface for a subsequent concreting of a section of the board of the bridge, with the cart being fixed in the position thereof. | 04-28-2016 |
