A system includes apparatus and methods for providing continuous structural support to footings and hollow core wall units. In operation, wire rope chairs, connectors, wedge pins, and a tensioner tool are used to interconnect wire rope within footings and hollow core wall units laid on the footings, allowing for continuous wire rope within selected units that when grouted, provide an interconnected reinforced structural wall that is safer to install than traditional methods, with other advantages.

A rebar spacer installed in a rebar crossing portion includes a spacer body and a pair of installation metal fittings. The spacer body includes a main portion and a pair of leg portions integrally formed with the main portion. The pair of leg portions is protrudingly provided with an interval on a rebar-side surface of the main portion. The interval between the pair of leg portions is equal to or larger than a diameter of the rebar and a depth of the pair of leg portions in an installation direction is equal to or less than the diameter of the rebar. Each one of the pair of installation metal fittings has a structure such that one end portion is locked into one of the pair of leg portions and the other end portion is hooked on a back-side rebar.

The disclosure herein discloses a rebar tying tool that ties plural rebars using a wire. The rebar tying tool includes a housing and a twisting motor, and may include a twisting mechanism that twists the wire around the plural rebars by the twisting motor. The twisting mechanism may include a screw shaft, a gripping member that grips the wire in cooperation with rotation of the screw shaft, a first reduction mechanism that reduces and transmits rotation of the twisting motor to a relay shaft, and a second reduction mechanism that reduces and transmits rotation of the relay shaft to the screw shaft. The first reduction mechanism may be a coaxial reduction mechanism, and the second reduction mechanism may be a parallel-axis reduction mechanism.

An apparatus or system for reinforcement bar (rebar) joint recognition using artificial intelligence vision includes a rebar tying tool attached to a micro manipulator; and a macro manipulator for moving the position of the micro manipulator; wherein the macro manipulator is adapted to move the micro manipulator on a first plane; the micro manipulator is adapted to move the rebar tying tool on a second plane parallel to the first plane and at a first axis vertical to the second plane.

A rebar holster system includes a vertical holster having an upper portion, a lower portion, and a middle portion. The upper portion includes an opening, the opening of the upper portion having a greater diameter than the vertical reinforcing bar such that the upper portion is dimensioned and configured for loosely receiving a leading end of the vertical reinforcing bar. The lower portion includes a securing means for securing the leading end of the vertical reinforcing bar to the vertical holster. The middle portion is disposed between the upper portion and the lower portion for guiding the leading end of the vertical reinforcing bar from the opening of the upper portion to the securing means of the lower portion.

An element for thermal insulation between two building parts, including an insulating body to be arranged between the two building parts and reinforcement elements in the form of at least tensile elements, extending in the installed state of the element essentially horizontally and perpendicularly to the essentially horizontal extension of the insulating body through said body, and respectively projecting in the horizontal direction from the insulating body and here allowing a connection to one of the two building parts preferably made from concrete. The tensile reinforcement elements are formed as multi-part composite elements such that at least in the area of the insulating body they exhibit a central section projecting from the insulating body and at least partially being made from fiber-reinforced synthetic material. The tensile reinforcement elements have in an area outside the insulating body at least one anchoring section with geometric and/or material characteristics at least partially deviating from the central section, with the anchoring section being connected to the central section in a connection area. The connection area is arranged distanced from the insulating body. The central section is made from a cylindrical rod-shaped and/or tubular material and is provided on its radial exterior, at least in an area between the insulating body and the connection area, with an essentially smooth wall.

A module for constructing foundations for a structure, comprising: a plurality of formwork members that define a pair of side walls that define a space between the side walls; thereto to hold the side walls in a spaced relationship; a three dimensional reinforcement cage that includes the brace, a plurality of first members, and a plurality of second members perpendicular to the first members, the first members coupled to at least the brace and the second members coupled to at least one of the plurality of the first members and the brace, wherein the cage forms an internal support within the space between the side walls for receiving a settable material, such that the side walls become integrated with the internal support as the settable substrate sets, to form the module.

A double winding reinforcement method has a main bars erecting step, a reinforcement stirrup winding step, and a reinforcement bar double ends winding step. In the main bars erecting step, multiple main bars are vertically disposed and are arranged in a rectangular shape. In the reinforcement stirrup winding step, a reinforcement stirrup is horizontally wound around the multiple main bars and is wound in a rectangular shape, and the main bars are defined as multiple pairs of opposite main bars. In the reinforcement bar double ends winding step, each reinforcement bar has a first end and a second end. The first end of each reinforcement bar is fixed with one of the main bars of a respective one of the pairs of opposite main bars. The second end is wound around the reinforcement stirrup and the other main bar of the pair of opposite main bars.
