A flooring system has at least one girder, a first joist coupled to a first side of the girder, and a second joist coupled to a second side of the girder. The flooring system further comprises a joist tightening system that has a first end coupled to the first joist and a second end coupled to the second joist, the joist tightening system pulls the first joist and the second joist toward the girder thereby tightening the first joist and the second joist.

The present disclosure relates to a device and a method for reinforcing a round section wood beam by the combination of a prestressed Fiber Reinforce Plastic (FRP) sheet and a high strength steel wire rope. The device includes an FRP sheet adhered to a bottom surface of a log beam in the length direction. A middle supporting piece is mounted in the middle of the log beam. An end part reinforcing anchoring piece is mounted at each of two ends of the log beam. FRP hoops are adhered to the log beam and are located between the middle supporting piece and each of the end part reinforcing anchoring pieces at intervals in the length direction. High strength steel wire ropes with both ends connected to the corresponding end part reinforcing anchoring pieces are respectively arranged on the two sides of the middle supporting piece.

This method is suitable for the strengthening of concrete or timber structures (1, 4) by applying prestressed Carbon FRP or Glass FRP lamella (8). Firstly, at least one groove (22) is cut into the concrete or timber structure (1, 4) along the direction in which the concrete or timber structure (1, 4) is to be strengthened. The grooves (22) are filled with epoxy resin (9) and a layer of epoxy resin (9) is put onto the entire section to be equipped with the CRFP or GFRP lamella (8). The lamella (8) will be prestressed and anchored at both ends. U-shaped brackets (24) are then being put over the two end sections of the CFRP or GFRP lamella (8) by inserting and submerging its both U-legs (27) into holes (26) filled with resin as well. These holding brackets (24) will then tightly press onto the CFRP or GFRP lamella (8) to prevent cracking or fracture of the concrete or timber and bending away of the extremities of the CFRP or GFRP lamella.

The invention relates to a method for the cambering of a wooden element, comprising the steps of: cutting to form at least one incision in a surface of the wooden element; inserting an expansive material into the at least one incision of the wooden element; letting the expansive material expand in the at least one incision so that a cambering of the wooden element is achieved.

A reinforcing structure for a wooden building, having: a first anchor bolt that is horizontally inserted into a concrete foundation of the wooden building and fixed to the concrete foundation by an adhesive agent; a second anchor bolt that is horizontally inserted into a wooden beam of the wooden building and fixed to the wooden beam by the adhesive agent; a reinforcing steel bar that is arranged between the first anchor bolt and the second anchor bolt; a first fixing member that connects and fixes the first anchor bolt and the reinforcing steel bar with each other so that the first anchor bolt and the reinforcing steel bar are orthogonal to each other; and a second fixing member that connects and fixes the second anchor bolt and the reinforcing steel bar with each other so that the second anchor bolt and the reinforcing steel bar are orthogonal to each other.

A rolling block restraint connector for forming a moment resisting connection at a joint intersection between a continuous column and at least a first continuous beam that intersects the continuous column is disclosed. The connector includes a first restraint assembly, a second restraint assembly, wherein the second restraint assembly is configured to be located diagonally across the joint intersection from the first restraint assembly, a first linkage that couples the first restraint assembly with the second restraint assembly, the first linkage including (i) a first saddle configured to couple with an exterior of a first end of a first tubular shaft of the first restraint assembly, and (ii) a second saddle configured to couple with an exterior of a first end of a second tubular shaft of the second restraint assembly, and a second linkage that couples the first restraint assembly with the second restraint assembly.

In an embodiment, an assembly includes a first plate comprising a first primary portion and a first flange disposed orthogonally to the first primary portion. The first primary portion is configured to contact a first structural member and the first flange defining a first through hole. A second plate comprises a second primary portion and a second flange disposed orthogonally to the second primary portion. The second primary portion is configured to contact a second structural member and the second flange defines a second through hole. A cover receives the second flange. A bolt is received through the first through hole, and tightening the bolt draws the first flange toward the second flange.

Certain exemplary embodiments can provide a two piece bracket constructed to reinforce a wooden joist. The wooden joist defines a central aperture. The central aperture is constructed to substantially surround a portion of a utility conduit passing therethrough. The two piece bracket is constructed to be positioned against one side of the wooden joist. The two piece bracket comprises a first piece and a second piece.
