A method of anchoring surface mounted strengthening systems to a structural member being repaired/strengthened or connecting the surface mounted strengthening systems to adjacent structural members to provide force-transfer or terminating a surface-mounted strengthening system includes drilling a hole in an existing structural member and inserting a portion of a fiber-reinforced anchor or connector into the hole in the existing structural member. The anchor or connector includes a bundle of fibers/rovings, and the portion includes rovings encapsulated in a pre-cured adhesive to form a reinforced portion having a desired cross-sectional size and shape to be received by the hole. The method further includes splaying free ends of the fibers/rovings at an end of the anchor and adhering the splayed ends of the fibers/rovings onto the surface-mounted strengthening system of the strengthened member or onto adjacent members with adhesive.

This solution is for washing and cleaning the external walls of a building, and adopts a lightweight six axis robotic arm mounted on a mini-gondola hoisted by a pulley system with the controlling motor located within the mini-gondola, while another set of motor located on the pulley system at the roof-top end drives the mini-gondola to traverse laterally on a set of twin-rails on the roof-top of the building. Four vacuum suction cups mounted on the minigondola through linear actuator are used to secure the mini-gondola to the wall. Each linear actuator has three ultrasonic distance sensors that measure and manage the distance between the mini-gondola and the wall to be cleaned. Once the gondola is in position, the robotic arm will be activated to start the cleaning process.

Carpet pad removal tools may include a handle and a headplate coupled to the handle. The headplate may include a plurality of teeth along an edge of the headplate that is angled relative to the rest of the headplate. Other aspects, embodiments, and features are also included.

The present invention provides an adjustable bolt-on brace attachment for strengthening standard field irrigation towers and tapered sections of field irrigations towers to stabilize a tower. In one aspect of the present invention, an attachment for stabilizing field irrigation towers allows the user to easily assemble the adjustable bolt-on brace in the field wherein three threaded ¾ inch rods span between the each of the three weight bearing poles of the field irrigation system. Each ¾ inch threaded rod is spanned between each pair of weight-bearing poles of a tower attaching at each pole by a galvanized steel two-sided clamp which is double bolted-on to each pole. The adjustable threaded rods may span from 15 inches to 49 inches of each of three tower faces and adjustable double sided steel clamps fit field irrigations tower legs sizes from ⅞ inch to 2½ inches diameter.

The present disclosure provides a spraying system and a using method thereof. The spraying system includes a lifting apparatus and a spraying apparatus. The spraying apparatus connects to the lifting apparatus and includes a stage, a multi-axis transfer mechanism, a spraying component, a driving component, a surface profile detector, and a controlling component. The multi-axis transfer mechanism is disposed on the stage. The spraying component is disposed on the multi-axis transfer mechanism and the stage. The driving component is disposed on the stage and connects to the lifting apparatus. The surface profile detector is disposed on the stage and scans an area to be sprayed to obtain scanning data. The controlling component is disposed on the stage and controls the lifting apparatus, the spraying component, and the driving component according to the scanning data and pre-stored initial data.

The invention relates to an inspection and repair module for an internal side wall of a vertically erected structure, with the module including a carrier for supporting at least one data recording mechanism and being securable to a hoist, and for an inspection and repair module for an internal wall of a conduit with the module including propulsion means comprising a set of driven tracked wheels controllable by a controller carried by the carrier and configured to provide, within a conduit, longitudinal forward and reverse motion.

A pre-fabricated construction panel (100) for use on an external surface and/or as part of a building or construction is provided. The panel comprises at least a first layer (110) which is at least partially provided from thermally insulating material having a first surface, said panel comprising at least a second layer (120), said at least second layer being provided from fiber cement board, said second layer having a second surface facing said first surface, said first and second layers being connected one to the other by a spacing means located between and adhering to said first and said second surface, which spacing means provides at least one interspace (140) between the first and second surface, said at least one interspace having at least two openings to the external of said panel for enabling air to flow into and out of the interspace towards the external of said panel. The thermally insulating material means material has a thermal conductivity (lambda) less than or equal to 0.05 W/mK.

A wafer for repairing damage to asphalt shingles comprising a first layer of a rubberized asphalt, a fiber matrix layer and a second layer of the rubberized asphalt. The first and second layers of rubberized asphalt sandwich and are bound to the fiber matrix layer forming an integrated wafer. The wafer is formed in a select shape.

A cleaning method includes controlling an unmanned aerial vehicle (UAV) to fly to a region of a wall body according to a path to be cleaned, and, in response to detecting a cleaning prohibition identifier associated with the region, recognizing the region as a cleaning prohibition region and controlling the UAV to fly over the cleaning prohibition region without cleaning the cleaning prohibition region.

An industrial chimney for wet stack operation is provided with an internal lining system attached to the inner surface of the chimney. The internal lining system comprises construction elements, that are arranged in a pattern, such that the joints between the construction elements in the pattern at the flue gas side of the internal lining system are inclined at an angle α of at least 5 degrees from horizontal.
