20150159340 | REINFORCED EARTH - The present invention concerns a method of installing a reinforcement strip in a compacted fill retained by facing element together with the reinforcement strip extending between an anchorage zone and the wall. The anchorage zone is located away from the facing element and separated from the facing element. The method comprises: a) installing ( | 06-11-2015 |
20150125221 | RETAINING WALL - Void former assembly for casting facing elements for reinforced earth. Anchoring recesses are cast into its rear face so that earth-reinforcing strips can be looped through. The anchoring recesses are each formed as a loop channel having a convex inner surface and a concave outer surface, at least one of which has a radius of curvature which increases from the deepest part of the recess towards the rear face. A removable void former assembly and method for casting such facing elements are also described. Because of the varying radius of curvature of the surfaces of the channel, and the rotational and translational withdrawal path of the void formers, the channel can be cast deeper, and with openings which are closer together, than has hitherto been possible using removable void formers. | 05-07-2015 |
20150048043 | HEAVY LIFTING APPARATUS AND METHOD - A crane apparatus and method are described for lifting a heavy load such as a wind-turbine generator unit | 02-19-2015 |
20140291374 | TENSION MEMBER FEEDING DEVICE - The present invention concerns a tension member feeding device for feeding a tension member into a channel in a construction element. The feeding device comprises: tension member feeder and a resistance or speed detector. The feeding device is arranged to stop feeding of the tension member once the resistance or speed detector detects that the tension member meets a given resistance. | 10-02-2014 |
20130186019 | SEALING ARRANGEMENT - The present invention relates to a sealing arrangement ( | 07-25-2013 |
20130180095 | Method and reel device for threading tendons into ducts - A method is described for threading a tendon into a duct from an opening at an intermediate point along the length of the duct. Opposite ends of the tendon are threaded from a reel into the two halves of the duct. The tendon is wound on to the reel such that both ends of the tendon can be unwound into the duct simultaneously. A reel and a method for winding the tendon on to the reel are also claimed. The method and reel are particularly suitable for threading coated steel tendons into PT ducts in tall structures such as containment vessels. | 07-18-2013 |
20130140509 | "METHOD AND SYSTEM FOR EQUALLY TENSIONING MULTIPLE STRANDS" - A method and system are described for tensioning structural strands | 06-06-2013 |
20130020732 | Adjustable Formwork Climber - An adjustable Formwork climber apparatus is described which may be used for casting walls having an overhanging portion. The climber is used for supporting both vertical and horizontal formwork on the same supporting brackets. Adjustment mechanisms are provided for positioning or tilting the vertical and horizontal formwork. The adjustable formwork climber can be used both for casting continuous vertical structures, and for structures having an overhanging or protruding portion such as a ring-beam. | 01-24-2013 |
20130007966 | STRAND GUIDING DEVICE - The present invention relates to a strand guiding device that comprises a curved body having a first end and a second end. The strand guiding device further comprises at least one channel extending from the first end to the second end inside the strand guiding device, the channel being arranged to be traversed longitudinally by a strand of a cable, and further arranged to hold the strand in place when under tension. The body of the guiding device is filled with a protective material for protecting the strand from corrosion and allowing later removal of the strand. | 01-10-2013 |
