Binding machine
A binding machine includes: a twisting unit configured to twist a binding member which is guided in a loop shape so as to wrap around an object, and thus to bind the object; a twist motor configured to drive the twisting unit; a circuit board having a mounting surface on which a control unit configured to control the twist motor is mounted; a body portion housing the twisting unit, the twist motor and the circuit board; and a handle portion protruding outward from the body portion. The circuit board is arranged between the twist motor and an inner wall surface of the body portion which is located toward the handle portion in such a manner that the mounting surface faces the inner wall surface and the circuit board is closer to the twist motor than the inner wall surface.
Intermediate anchor assembly
An intermediate anchor assembly includes an encapsulated anchor having a front and rear encapsulation extensions. The assembly includes a cap with an outer surface and a front tube with an inside diameter that is greater than the outer diameter of a tension member. The assembly includes a front adapter that sealingly couples to the outer surface of the cap and sealingly couples to the outer surface of the front tube. The assembly includes a rear tube having an inside diameter that is greater than the outer diameter of the tension member. The assembly includes a rear adapter that sealingly couples to the rear encapsulation extension and sealingly couples to the outer surface of the rear tube. The assembly includes a first split seal sealingly fit between the tension member and the front tube and a second split seal sealingly fit between the tension member and the rear tube.
Binding machine
A binding machine includes a wire feeding unit, a binding unit, a curl guide and an inductive guide. The inductive guide has a converging passage through which the wire fed by the wire feeding unit and curled by the curl guide passes, and a cross-sectional area of the converging passage decreases along an entry direction of the wire from an opening end portion that the wire enters. The inductive guide has an entry angle regulation part configured to change an entry angle of the wire entering the converging passage, and the inductive guide is provided on an inner side with respect to a virtual line interconnecting the opening end portion and a narrowest part of the converging passage at which the cross-sectional area is the narrowest.

The assembly includes a rear tube having an inside diameter that is greater than the outer diameter of the tension member. The assembly includes a rear adapter that sealingly couples to the rear encapsulation extension and sealingly couples to the outer surface of the rear tube. The assembly includes a first split seal sealingly fit between the tension member and the front tube and a second split seal sealingly fit between the tension member and the rear tube.
Apparatus for tying wire around one or more objects
An apparatus for tying a wire around one or more objects, such as concrete reinforcing includes a wire feed roller configured to pass a wire around the objects to form a loop, a wire twister configured to twist the sides of the loop together, and a guiding surface arranged to deflect the wire as it is being twisted so that the ends of the wire finish pointing at least partially in the direction of the objects being tied.
3D CONCRETE PRINTING WITH WELL ANCHORING CORDS
A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104, 108) reinforcing at least one of the two or more layers. The elongated steel element (104, 108) is provided with a first crimp. Due to the crimp, a good anchorage in concrete is obtained and the anchorage force is predictable, since the standard deviation of the anchorage force is very small. The elongated steel element can be a single steel wire with a diameter D, the amplitude of the crimp ranges from 1.05×D to 5.0×D. The elongated steel element can also be a steel with steel filaments having a maximum diameter d. The amplitude of the crimp ranges from 1.05×d to 5.0×d.
BINDING MACHINE
A binding machine includes a wire feeding unit that feeds a wire, a curl forming unit that forms a path along which the wire fed by the wire feeding unit is to be wound around an object, a cutting unit that cuts the wire wound on the object, a binding unit that twists the wire wound on the object and cut by the cutting unit, and a drive unit that drives the binding unit. The drive unit includes a motor and a decelerator that perform deceleration and amplification of torque. The decelerator includes a sun gear, a planetary gear in mesh with the sun gear, a planet cage that supports the planetary gear, and an internal gear in mesh with the planetary gear. The planet cage is rotatably supported on one side and the other side along an axis direction.

REBAR TYING TOOL
A rebar tying tool may include a holder, a stopper, a driving roller, and a driven roller. The stopper may be configured to switch between a prohibiting state in which the stopper prohibits a reel from detaching from the holder and an allowing state in which the stopper allows the reel to detach from the holder. The driving roller may be configured to rotate. The driven roller may be configured to switch between a clamped state and a non-clamped state, the wire may be clamped between the driving roller and the driven roller when the driven roller is in the clamped state, and the wire may not be clamped between the driving roller and the driven roller when the driven roller is in the non-clamped state. The driven roller may be in the non-clamped state at all times while the stopper is in the allowing state.
SHEARING APPARATUS AND PROCESS FOR POST TENSIONING TENDON
A table shear may include a clamp and a shearing mechanism, the shearing mechanism supported by the clamp. The shearing mechanism may include a fixed lower shear blade, a lower shear blade backup plate supporting the fixed lower shear blade, a moveable upper shear blade and a shear compression cylinder. The shear compression cylinder abuts the movable upper shear blade.
