A tool for manufacturing of a reinforcement bar structure, wherein the tool comprises a main body, a jaw arrangement, a tying device and an arrangement configured for moving the jaw arrangement between a gripping state and a tying state. A system for manufacturing a reinforcement bar structure, wherein the system comprises a supply of reinforcement bar material, a bending apparatus, a holding apparatus and a group of robots wherein at least one robot of the group of robots is equipped with the tool for manufacturing a reinforcement bar structure. A method for transporting and attaching a reinforcement bar during manufacturing of a reinforcement bar structure using a tool comprising a main body, the method comprising gripping a reinforcement bar, tying together the reinforcement bar with another reinforcement bar by looping a wire around the reinforcement bars, tightening the wire around the reinforcement bars, forming a knot, and cutting the wire.

A concrete forming system for reducing the time and labor required for the framing, pouring, and curing of concrete walls. The concrete forming system generally includes concrete forms including a first wall, a second wall opposing the first wall, and a pair of sidewalls. A cavity is formed between the walls; with an opening being fluidly connected to the cavity. A first vehicle is connected to the first wall and a second vehicle is connected to the second wall. Using the vehicles, the positioning and orientation of the walls may be adjusted. After the walls have been placed and oriented, the vehicles will hold the walls in place as concrete is poured into the cavity through the opening. The concrete is allowed to cure into a structure; after which the vehicles and walls may be moved to another location to repeat the process.

A modular building formwork apparatus includes a formwork wall and at least one interlocking device. The formwork wall includes a wall plate and a frame disposed on the wall plate. The frame has an aligning hole and a locking hole. The interlocking device includes a housing unit, a rotation transferring unit, a transmitting unit and a locking member. The rotation transferring unit has an input shaft and an output shaft. The transmitting unit is movable relative to and rotatable about the output shaft. The locking member has a head portion, a positioning portion and a threaded portion. The locking member is insertable into the aligning hole to permit the threaded portion to threadedly engage in the locking hole.

An interlocking device is adapted to lock two modular building formworks. Each formwork includes a wall plate and a frame. Each frame has aligning and locking holes. The interlocking device includes a housing unit secured to the frame, a rotation transferring unit having intersecting input and output shafts, a transmitting unit movably coupled with the output shaft, and a locking member having a head portion, a positioning portion and a threaded portion. The locking member is insertable into the aligning hole of one frame to have the head portion abutting against the frame, and the threaded portion is matingly engageable in the locking hole of the other frame so as to lock the two formworks.

A building formwork apparatus includes a building formwork having a frame with a positioning hole and a locking hole, and a locking member including a first tapered section, a second tapered section connected to the first tapered section, and a threaded portion connected to the second tapered section. The positioning hole is configured to receive insertion of the locking member therethrough such that the first tapered section is retained therein and the second tapered section is exposed therefrom for connection with another building formwork apparatus. The locking hole is configured to receive a threaded portion and a second tapered section of a locking member of the another building formwork apparatus.

A lifting hook including a fixed portion and a moving portion coupled to the fixed portion, the moving portion being pivotable between a locking position in which the moving portion retains a profile of a formwork panel housed in a housing of the fixed portion, and a release position in which the profile of the formwork panel can be introduced into or extracted from the housing. The lifting hook also includes a pushing part coupled to the fixed portion which pushes the moving portion when the pushing part is pulled.

A method for assembling at least one slab table for at least partial formworking of a concrete slab, which has a carrier skeleton, at least one formwork element, and at least one support.

The invention relates to a sheet (10) for protecting a form-work surface, intended to surround a construction material. According to the invention, the sheet (10) comprises at least: a front layer, including at least one polymer material and provided to be in contact with the construction material so as to reduce wear and the formation of grooves on the framework surface and to limit adhesion of the construction material during removal of the formwork; and a rear adhesive layer, provided to be positioned against the formwork surface and rigidly connect the sheet (10) to the formwork surface before the construction material is introduced. The invention also relates to a formwork installation (1) equipped with at least one such sheet (10). The invention further relates to a method of producing and a method of using a sheet (10) of this type.

A two-way retractable building formwork apparatus includes a substrate module having a mounting surface, a first side bar mounted on one end of the mounting surface that extends along a first direction, a second side bar mounted on another end of the mounting surface that extends along a second direction transverse to the first direction and fixed to one end of the first side bar, a first retractable unit mounted on the mounting surface opposite to the first side bar and extendable along the first direction to fixedly connect to the second side bar, and a second retractable unit mounted on the mounting surface opposite to the second side bar, extendable along the second direction to fixedly connect to the first side bar, and further connected to the first retractable unit.
