A barrier cable coupler for coupling two lengths of barrier cable comprises a coupler body including a threaded inner surface, a first end, and a second end; a fixed retaining collar having an outer surface and being retained to the first end of the coupler body, the fixed retaining collar including a tapered inner surface; one or more fixed end wedges positioned within the tapered inner surface of the fixed retaining collar; a tensioning retaining collar having an outer surface, the tensioning retaining collar positioned at least partially within the second end of the coupler body and including a tapered inner surface; one or more tensioning end wedges positioned within the tapered inner surface of the tensioning retaining collar; and a tensioning nut including a threaded outer surface engaging the threaded inner surface of the second end of the coupler body and retaining the tensioning retaining collar therein.

A method including placing a screed hardware unit upright on a surface. The hardware unit includes a base and a post. The base is fastened on the surface such that the post extends vertically from the base. The method further includes adjusting a height of the hardware unit so as to be consistent with a desired grade. Concrete is poured up to and/or around the hardware unit, and the concrete is screeded at the grade indicated by the height of the hardware unit.

An apparatus including a base. The base includes a post mount portion disposed on a first side of the base. The apparatus further includes an adhesive member that attaches to a second side of the base. The adhesive member includes an adhesive and a cover disposed on the adhesive. The cover is removable to expose the adhesive. A post having a distal end and a base end is attachable to and detachable from the base member at the post mount portion.

A concrete dowel placement system and methods for making the same. The system allows for accurate and easy substantially-parallel or parallel placement of slip dowels within sections of concrete so that adjacent sections of concrete may be allowed to undergo thermal expansion and contraction while remaining in a common plane without cracking or faulting. The system includes a coupler and a sheath. The sheath is configured to be slidably extensible over the coupler and may be held to the coupler by friction. Additionally, a method of constructing the concrete dowel placement system includes extruding material to form two tubes of different sizes. The tubes are then attached to each other, then material is extruded to form a sheath. Alternatively, construction may include extruding material to form a tube, then removing some of the material from the tube in order to form a coupler.

Improvements in machine walls to construct a building or house is disclosed. Adjacent side of the wall sections are tapered and dovetailed that lock-in-place. The dovetails are spaced to reduce the height that one section must be lifted to engage in an adjoining wall section. The footers/base plate will also have integrated earthquake or hurricane hold-downs in the footer/base plate that aligns and can be secured from the foundation to the wall sections. The connection of the wall section to the foundation to have counter flashing at the concrete insert and the wall-to-wall sections can be self-flashed. The wall sections can have GPS locators for positioning the wall sections. Plumbing and electrical conduit creating circuits that can be integrated into the walls and are connected sealed or bonded together.

An anchor assembly for being embedded in concrete includes a metal plate including an opening, the metal plate including a top surface and bottom surface; the opening including a wall extending from the top surface or the bottom surface; and a threaded rod operably attached to the metal plate.

An apparatus, system, and method is provided to connect precast concrete panels to a structural member. The connector can have a receiving member embedded in a precast concrete panel and can further have an attachment member that selectively interconnects to the receiving member. This attachment member can have a surface that is oriented substantially perpendicular to the precast concrete panel and that receives or supports a structural member such as a floor joist or a second precast concrete panel. The configuration of a protrusion of the attachment member allows for a rapid and secure interconnection with an aperture in the receiving member. A builder can use the connector system described herein to rapidly and securely assemble multiple precast concrete panels to structural members in the construction of, for example, a parking garage or other similar structure.

An anchor assembly (10) comprises an anchor (12) comprising a body (15) defining a cavity (16). The anchor (12) further comprises a reinforcing member (18) extending through the cavity (16) and outwardly from the body (15). The anchor assembly (10) further includes an insertion device (14) insertable into the cavity (16). The insertion device (14) comprises a securing member (49) movable between securing and non-securing positions. When the movable securing member (49) is in the securing position in the cavity (16), the securing member (49) can engage the reinforcing member (18) to secure the insertion device (14) to the anchor (12).
