A V-shaped tie hoop assembly enhances field construction performance by integrally forming a plurality of V-shaped tie hoops after constituting the plurality of V-shaped tie hoops in a bundle form, maintains intervals, and enhances reinforcement performance. The V-shaped tie hoop assembly can includes: a plurality of V-shaped tie hoops, each of which has a bending part at the center thereof and anchor parts extending to opposite sides of the bending part, and disposed at different heights at an interval; and a vertical support bar connecting all of the V-shaped tie hoops to integrally couple the V-shaped tie hoops.

A clipping apparatus for holding rebar is disclosed. The clipping apparatus includes having a first base portion and a second base portion. Extensions and clips are positioned in the base portions to hold one or more rebar rods or wires in a stable orientation. Platforms are positioned to give a user a plane upon which to apply an engaging force to clip the rebar into the clipping apparatus. A chair arrangement is positioned to provide spacing between adjacent planes of rebar. A fluid-stop section is positioned about the first base portion and the second base portion. The fluid-stop section also includes a raised rim. Together with the base, platforms, and chair, the fluid-stop section to help prevent flow of liquid through the clipping apparatus.

A rebar tying tool may include a twisting mechanism, a body, a grip, and a control board. The twisting mechanism may include a twisting motor and a holder configured to twist a wire around rebus by operation of the twisting motor. The body may house the twisting mechanism. The grip may be disposed below the body and configured to be gripped by an operator. The control board may be configured to control the operation of the twisting motor. The control board may be disposed below a connection between the grip and the body.

A reinforcement arrangement and a method for producing a construction material body using the reinforcement arrangement. The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations. In the function position, a free end of the holding section opposite the foot section is larger than in the storage position. The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.

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 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 tool device is for positioning a reinforcement mesh for concrete. The tool device may include a lever arm having a first end, a second end opposite the first end, and a pivot point between the first end and the second end. The tool device may include a pivoting vertical support coupled to the lever arm at the pivot point and cooperating with the pivot point to rotate about the pivot point, and a toe coupled to the first end of the lever arm and to engage the reinforcement mesh.

A V-shaped tie hoop assembly enhances field construction performance by integrally forming a plurality of V-shaped tie hoops after constituting the plurality of V-shaped tie hoops in a bundle form, maintains intervals, and enhances reinforcement performance. The V-shaped tie hoop assembly can includes: a plurality of V-shaped tie hoops, each of which has a bending part at the center thereof and anchor parts extending to opposite sides of the bending part, and disposed at different heights at an interval; and a vertical support bar connecting all of the V-shaped tie hoops to integrally couple the V-shaped tie hoops.

The reinforcing panel for reinforced concrete structures comprises a plurality of sticks (2) suitable for being arranged parallel to each other through a panel (12) of insulating material. The sticks (2), near the opposite ends (20), have a corresponding pair of slots (4, 5) protruding bilaterally in use from said panel (12) of insulating material. The slots (4, 5) are suitable for engaging and retaining reinforcing metal wires (6) on orthogonal planes.

A disclosed rebar coupler includes a first coupling member, a second coupling member, and a coupling means. Accordingly, the connection angle between the first coupling member and the second coupling member is variable to a desired angle. The connection angle between rebars to be connected may be rapidly and conveniently varied at an industrial site to which the rebars are applied.
