20080236061 | Floor slab support system - A floor slab support system for jacking and stabilizing a sagging or cracked floor or other such slab. Holes of 3½″ diameter, for example, are drilled through the slab and a pipe pier driven downwardly until reaching bottom. A connector sleeve matching the slab hole size is temporarily suspended in the slab hole and L shaped brackets are inserted into the sleeve and maneuvered to extend outwardly through slots in the sleeve to engage the underside of the slab. A threaded rod with a threaded positioning member and a bottom stop is inserted through the sleeve and into the pipe pier, and the L brackets extended through the sleeve and maintained outwardly by the threaded positioning member. Once in position, the threaded rod is rotated to screw the sleeve and brackets upwardly to support the slab. Finally, the top of the rod is cut off and the hole filled with concrete. | 10-02-2008 |
20100186313 | Slab Lift Bracket - The present invention provides a slab lift bracket that includes an collar portion with a center, an upper surface, a lower surface, an outer surface, and an inner surface. The slab lift bracket also includes a plurality of protruding members that are distributed around and fixed to the collar portion. The protruding members extend outwardly and downwardly of the collar portion at spaced apart locations, and have a hook shaped free end. | 07-29-2010 |
20110056150 | System for Forming a Movable Slab Foundation - An embodiment of the system for forming a movable slab foundation as comprised by the present invention has a slab foundation, at least one support surface, at least one lifting member, at least one support sleeve, and an engagement device carried by the at least one support sleeve. The at least one support sleeve is encased within the slab foundation and its lower end is positioned in abutting contact with the at least one support surface. The at least one lifting member is inserted through the at least one support sleeve. The at least one support sleeve and the slab foundation are moved upward axially along the length of the at least one lifting member. The engagement device is engaged with the at least one lifting member, thereby securing the slab foundation and the at least one support sleeve at a desired height. | 03-10-2011 |
20120210656 | Holder for Being Positioned in Floating Floor Slabs and Installation System Thereof - A holder to be placed in floating floor slabs and the installation system thereof, the holder comprising a cubic holder having a pair of tubes on each side thereof, parallel with the supporting base, with facing sides in identical position; within said sides a section designed for placing rods on which the different layers of the rebar mesh are supported and a system for fitting the mesh on the rods, and also the securing of the corners of the different levels of the rebar mesh by means of linking of the holder s using the rods. | 08-23-2012 |
20130067832 | LIFT-SLAB CONSTRUCTION SYSTEM AND METHOD FOR CONSTRUCTING MULTI-STORY BUILDINGS USING PRE-MANUFACTURED STRUCTURES - The present invention integrates the use of pre-manufactured structures with minimal on-site installation and lift-slab construction to achieve the construction of multi-story buildings. The pre-manufactured structures are designed to be readily integrated with both horizontal and vertically adjacent building components, including lift-slab components, so that multiple building stories may be readily and securely stacked, one on top of the other. The present invention advantageously permits top- down lift-slab construction for multi-story buildings. The present invention also provides for the development of flexible design plans for institutional, residential, office and other types of buildings. The present invention advantageously provides for easier, more efficient, faster, cheaper, safer, higher quality and more consistent, environmentally advantaged, energy-efficient, easier to maintain, intelligently designed, and customizable multi-story building construction. | 03-21-2013 |
20130269269 | System for Forming a Movable Slab Foundation - An embodiment of the system for forming a movable slab foundation as comprised by the present invention has a slab foundation, at least one substantially vertical support member, at least one support surface, and at least one support sleeve. The at least one supports sleeve surrounds the at least one support member and is encased within the slab foundation and is capable of movement axially along the axis of the at least one support member. The at least one vertical support member is capable of rotation relative to the at least one support sleeve to restrict the movement of the at least one support sleeve downward relative to the at least one vertical support member, thereby maintaining the height of the at least One support sleeve and the slab foundation relative to the at least one support surface. | 10-17-2013 |
20140053475 | METHOD AND APPARATUS FOR LIFTING AND LEVELING A CONCRETE PANEL - A lifting apparatus to be embedded within a precast concrete panel or slab to enable the panel to be lifted, positioned atop a road bed, and elevated above the road bed. A lifting apparatus is located at each corner of the panel. Each lifting apparatus has a threaded sleeve extending through the panel to receive a removable threaded lifting bolt by which to establish a lifting point at which a lifting force is applied to lift and position the panel. When the threaded lifting bolt is rotated completely through the threaded sleeve, a pushing force is applied against a base plate, whereby to elevate the panel above the road bed as is necessary to make the panel level with adjacent panels during the construction or repair of a roadway. Grout is pumped through the panel to fill the space between the panel and the road bed. | 02-27-2014 |
