BUILDING SYSTEM

Up First Construction Sys...

1. A collapsible jack for displacing a building structure, the jack comprising:a central mast having an inner core and an outer shell adapted to slide along the inner core in a telescopic configuration;
a drive system for moving the outer shell along the inner core to selectively displace the jack between a contracted condition and an extended condition;
a carriage slidably mounted on the outer shell; and,
a cable and a pulley system for selectively displacing the carriage between a first location and a second location on the outer shell, the pulley system being located at an upper portion of the outer shell wherein, in use, the cable and the pulley system operate to displace the carriage during sliding movement of the outer shell along the inner core.

SYSTEM AND METHOD FOR CLEANING EXTERNAL WALLS OF BUILDING

Elid Technology Internati...

1. A wall cleaning system for spray cleaning external walls of building, the system comprising:a gondola for hanging on a motor driven pulley system, wherein the motor driven pulley system comprises a pair of rails and a set of motors located at roof-top end of the pulley system; wherein the pair of rails are disposed in a horizontal plane on the roof top, and the hanging gondola is disposed in a vertical plane in parallel to an external wall; thereby, when the set of motors drives the pulley system along the pair of rails in the horizontal plane, the gondola operationally traverses in the vertical plane along the pair of rails along a linear distance of the rails for a water spraying process to be carried out; wherein the gondola comprises a controlling motor of the pulley system that hoists and lowers the gondola in parallel to the external wall of the building to be cleaned, wherein the controlling motor is located within the gondola;
a six-axis robotic arm, coupled with a 3D camera, and a spray nozzle on its end effector, the six-axis robotic arm is seated on the gondola for carrying out water spray cleaning on the external walls;
wherein the 3D camera mounted on the robotic arm operationally scans a wall area to be sprayed clean; and
a software program adapted for receiving the scanned results from the 3D camera and calculating the trajectory path of the spray cleaning motion for the robotic arm.

SEALING PLUG FOR CLOSING HOLES IN WALLS AND THE LIKE

20 EMMA 20 S.L., Aduna (...

1. A plug for closing a hole in a wall that holds a fluid, the wall having an inner surface that defines the hole, the plug comprising:an elastic body having a central axis, a first end, a second end, an inner surface and an outer surface, the inner surface defining at least in part an internal cavity; and
a stem having a first part that resides inside the internal cavity and a second part that resides external to the elastic body protruding from the first end of the elastic body, the first part being operatively coupled to the elastic body so that a pulling on the second part causes the elastic body to axially compress and radially expand to exert a first pressure on the inner surface of the wall that defines the hole when the plug is located inside the hole;
the first end of the elastic body having a through opening that fluidly communicates the internal cavity with the fluid held by the wall so that when the plug is located inside the hole and the elastic body is radially expanded the fluid applies pressure against the inner surface of the elastic body to cause the pressure applied to the inner surface of the wall that defines the hole to be greater than the first pressure.
