Abstract: The threaded deformed reinforcing bar is used in concrete construction and may be easily connected to other threaded deformed reinforcing bars by an internally threaded coupler. The threaded deformed reinforcing bar has a continuous spiral thread upon at least a portion of its length which engages the internally threaded coupler. The continuous spiral thread upon the deformed reinforcing bar is formed by eliminating portions of longitudinal ribs that are formed upon the reinforcing bar during manufacturing. This process for forming the threaded deformed reinforcing bar is less expensive than conventional processes.

Abstract: Apparatus and methods that reduce wind loads on polygonal monopoles, such as antenna towers and other telecommunication structures, exposed to winds. A multiplicity of connected segmented truncated conical shrouds are attached along at least a portion of the length of a polygonal monopole (telecommunication structure or antenna tower) that surround it. The presence of the multiplicity of segmented conical shrouds changes the profile of the monopole from multi-sided or faceted polygonal to conical. Based on the specifications of the TIA/EIA-222-F which is the governing code for telecommunication structures, the reduction of the wind load on a 12-sided polygonal monopole is on the order of about 42 percent, on a 16-sided polygonal monopole is on the order of about 18 percent, and on a 18-sided polygonal monopole is on the order of about 9 percent.

Abstract: A framing member incorporates a plurality of recesses along a portion of the member that are configured to receive a screw tip. The recesses are formed in the flange region or the connecting region. The recesses are formed by piercing or stamping the metal framing member. The configuration of the recesses can allow the manufacturer to further down gage the stud, resulting in a significant cost reduction opportunity and cost savings for the manufacturer, contractor as well as improved customer satisfaction.

Abstract: Adjacent precast reinforced concrete modules or members are secured together by a plurality of coupler systems each including a cast metal coupler body embedded in an edge portion of the first concrete member and connected by a coupling member to a reinforcing bar within the first concrete member. The coupler body has an internal cavity with a side opening and an end opening extending to the cavity, and reinforcing wings border the side opening. The second concrete member has another coupling member rigidly connected to an axially aligned reinforcing bar and includes an end portion with a threaded bore. A bolt is inserted into the cavity through the side opening, aligned with the end opening and then threaded into the bore where the bolt is tightened with a wrench extending into the cavity through the side opening. A reusable locating pin may be used to align the concrete members.

Abstract: A connector sleeve 22 is disclosed for connecting two beams 2,4 together in the construction industry which is quick and easy to use and which may be moved or removed if required. The sleeve 22 comprises opposing walls 25,26 for receiving the end portions of two beams 2,4 therebetween and clamping means 32 integrally mounted on one of the opposing walls 25,26. The clamping means 32 is configured to releasably engage the beams 2,4 in use so as to fix their location relative to each other. A modular connection assembly for connecting two beams is also disclosed herein.

Abstract: Masonry walls of buildings supported on concrete foundations are strengthened against destructive wind and seismic forces by spaced elongated members inserted inside the hollow masonry walls. The spaced elongated members are secured to the continuous masonry bond beam and the foundation. Tension means at the top of the masonry wall make the elongated members taut creating a continuous tension load path from bond beam to the foundation.
