Reinforcing systems to strengthen monopole towers

InactiveUS7905069B1Optimize vertical distanceOptimize spaceBuilding repairsFoundation repairEngineeringTower
An existing vertical monopole tower is reinforced by a plurality of vertically extending metal reinforcing members in the form of elongated channel members or angle plate members or ribbed plate members. The reinforcing members have longitudinally spaced holes which align with vertically spaced holes in the tower wall, and blind fasteners extend through the aligned holes to secure the reinforcing members to the tower. The fasteners provide for transferring only tensile forces or tensile and shear forces to the reinforcing members. Vertically aligned reinforcing members have adjacent end portions spliced together by splice plates and blind fasteners, and the splice plates are fastened to the web portions of the channel members or the ribs of the rib plate members or the wing portions of the angle plate members. Shear plates and pin assemblies may also be used to transfer shear forces and in splicing vertically aligned reinforcing members.

Method for reinforcing underwater structure by fiber-reinforced composite material grid ribs

The invention relates to a method for reinforcing an underwater structure by using fiber reinforced composite material lattice ribs, which comprises the following steps: treating the concrete surface of the underwater structure to be reinforced; coating at least one layer of the fiber reinforced composite material lattice ribs on the surface of the underwater structure to be reinforced; setting an isolator outside the underwater structure to be reinforced, and making the height of the isolator be more than or equal to the height of the fiber reinforced composite material lattice ribs coated on the surface of the underwater structure to be reinforced; sealing concrete at the bottom of the isolator; and filling underwater epoxy resin or underwater non-dispersed mortar or underwater non-dispersed concrete into the clearance between the isolator and the structure to be reinforced. The process is simple; because the treatment of abandoning and preventing water is not needed during construction, and the periphery of the underwater structure to be reinforced does not need to arrange a cofferdam, the construction process has little influence on a navigation channel; and the reinforcing cost is low, the reinforcing is quick, the construction period is short, and the durability of the structure can be effectively improved.

Structure for reinforcing concrete member and reinforcing method

In the structure for reinforcing a concrete member and the reinforcing method of the present invention, a reinforcing sheet is arranged and joined to a various kinds of concrete member, such as column, beam, wall, floor, and the like, by applying the reinforcing sheet to the surface of the concrete member and attaching to the fixing anchors joined to the concrete member or the other concrete member surrounding the concrete member. The fixing anchor comprises a large amount of reinforcing fiber, and is obtained by bundling a part of the reinforcing fiber. The unbundled portion of the fixing anchor is spread along the surface of the concrete member. The reinforcing sheet is over-lapped to the unbundled portion using resin adhesives. In addition, reinforcing fibers, such as carbon fiber, aramid fiber, glass fiber, and the like are preferably used as the material comprising the fixing anchor and reinforcing sheet. Thereby, the reinforcing member can be joined via the fixing anchor to the concrete members. Therefore, it is possible to securely join the edges of the reinforcing member, and reliably exert the reinforcing effects on the concrete member.

Expandable crack inhibitors and methods of using the same

One or more crack inhibitors can be installed to improve fatigue performance by producing stress states that prevent or inhibit crack initiation. Crack inhibitors can also prevent or retard crack growth. A mandrel can be used to radially expand the crack inhibitors to both induce compressive residual stresses and to form an interference fit between the crack inhibitor and a workpiece. The mandrel can be removed from the installed crack inhibitor, which is left in the workpiece to ensure proper stress states are maintained.

Underground storey-adding process of frame structural building by one-by-one independent foundation underpinning method

The invention relates to an underground storey-adding process of a frame structural building by a one-by-one independent foundation underpinning method. In the process, top beams and top supports of the building with a proposed basement and columns and foundations of the completed basement jointly support an upper structure of the building, and then earth excavation and construction of the columns and the foundations of the residual uncompleted basement are continuously carried out. Earth excavation and top support are simultaneously performed; after the original foundations are removed, the load of the upper frame columns is transferred to the adjacent foundations around the columns through the top beams and transferred to earth through the foundations; and after new foundations and an lower ground level underground frame column are constructed, the load of the upper frame columns can be jointly supported by the new foundations, beam supports and the adjacent foundations. Compared with 'a slab foundation underpinning method' in which the upper structure is simply supported by soil mass under slabs, the method is more reliable and can complete underground storey-adding in areas with worse soil property; compared with the underpinning mode of removing the foundations of the whole building simultaneously, the method is more safe; and even though engineering accidents happen, the building is locally but not integrally unstable.
