The invention belongs to the devices for automatic cleaning and ventilation of windows from the facade of high-rise buildings. The technical result of the proposed invention is the simplification of the construction of the device, which makes it possible to clean the glass surface without human resources, which is also financially profitable. In this case, the glass cleaning, which is carried out by a climber and costs from 7 to 28 dollars per square meter, is reduced to 1 dollar per square meter through the proposed invention. The essence of the invention lies in the fact that the proposed device contains an additional washing solution valve equipped with pipes, ventilation box, ozonator, filters, speakers and control panel, water valves, as well as a water valve with a flushing solution for the pipe. In the first section of the frame, the water valve is also connected to the outlet pipe.

An automated building washing device generally includes a spray bar assembly coupled to a window washing swing stage. The spray bar assembly is horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while spray heads rotate so that a relatively large portion of building surface can be quickly cleaned. The spray bar assembly includes a hollow rotating bar and spray heads inside of a shroud so that the bar can rotate as water or cleaning solution is sprayed onto the building surface for cleaning.

An automated building washing device generally includes one or more rotational brushes having a vertical rotational axis coupled to a window washing swing stage. The brushes are horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while rotating about their vertical axis so that a relatively large portion of building surface can be quickly cleaned.

A frame body may be parallel to and proximate with an external surface of a structure and extend substantially horizontally from a first side to a second side. A connecting portion may be provided to be attached to a cable to provide for vertical movement of the frame body. A robotic arm may be affixed proximate to a bottom of the frame body and be able to move horizontally during treatment of the external surface. Moreover, the robotic arm may extend to an end proximate with the external surface, and a cleaning portion may be attached to the robotic arm near the end proximate with the external surface. The robotic arm may rotate, vertically moving the cleaning portion during treatment of the external surface. In addition, the cleaning portion may be separately rotated to remain substantially parallel to and proximate with the external surface during rotation of the robotic arm.

A UHPC material for reinforcing existing stone masonry wall and its reinforcement method are disclosed, which belongs to the technical field of wall reinforcement. The UHPC material for reinforcing existing stone masonry wall includes: 550-600 kg/m.sup.3ofsilicate cement, 180-200 kg/m.sup.3ofwhite silica fume, 510-530 kg/m.sup.3 of limestone powder, 715-735 kg/m.sup.3 of quartz sand, 60-75 kg/m.sup.3 of iron ore tailings particles, 50-60 kg/m.sup.3 of pumice particles, 15-30 kg/m.sup.3 of polycarboxylic acid water reducing agent, 230-255 kg/m.sup.3 of water and 25-35 kg/m.sup.3 of POM fiber; the disclosure uses the combination of improved new UHPC increased cross-section method and steel banding method to strengthen the existing stone masonry wall, which can increase the thickness of the stone masonry wall and it can improve the stability of the wall; significantly improve the seismic performance and durability, and the construction is convenient, so it can be widely used in the seismic reinforcement of the stone masonry wall.

A system for substantially enclosing the periphery of a building top with a netting system which is easily and efficiently movable or reconfigurable during the building construction process comprises a lightweight netting system for extending above a completed work area or floor, a strong lightweight structural support system for the netting, wherein the structural support system is vertically adjustable via slidable engagement with brackets attached to the floors which are already completed, provides enhanced safety for workers and for pedestrians below by preventing passage of workers or debris through the netting and enhances efficiency of construction by providing an easily reconfigurable, inexpensive and lightweight system for providing such enhanced safety.

A tool for removing carpet from a floor. The carpet removal tool includes a panel having an elongated opening thereon. Opposing ends of the panel include handles pivotally affixed thereto to be grasped by one or more users, wherein the handles can be positioned parallel to or perpendicular to the panel. In operation, the user cuts a portion of the carpet to be removed and secures the end of the carpet within the elongated opening on the panel. The user then pulls using the handle so that the carpet wraps around the panel as it is removed from the floor. The carpet can be manually wrapped around the panel by the user.

A cladding kit is provided for a structure cladding, the structure cladding comprising a first panel that extends away from a structure location along a first surface portion of the structure and a second panel that extends away from the structure location along a second surface portion of the structure. The cladding kit comprises a base piece couplable to the structure at the structure location, the base piece comprising a base connector, and a trim piece comprising first and second wings and a trim connector shaped to make a connection with the base connector to thereby couple the trim piece to the base piece. The first wing is shaped to contact, and be deformed by, the first panel when a connection is made. The second wing is shaped to contact, and be deformed by, the second panel when the connection is made.
