A system for manufacturing 3D-printed building elements can include multiple production stations, some or all of which can be automated stations. Stations can include one or more printing stations, insulation stations, machining stations, and coating stations. Each printing station can have a large-scale 3D-printing system that automatically forms 3D-printed building elements. Each insulation station can automatically place insulation materials into 3D-printed building elements. Each machining station can automatically machine surfaces of 3D-printed building elements. Each coating station can automatically apply coating layers onto 3D-printed building elements. Each station can be configured to receive 3D-printed building elements in a vertical orientation from other stations and can also perform operations on 3D-printed building elements while they are in a vertical orientation. Additional stations can include relaxation, drying, and framing stations.

A concrete vibrator system includes a concrete vibrator having a motor, a vibratory head that is actuated by the motor, and a controller that controls the motor. The concrete vibrator system may also include one or more remote devices or servers that wirelessly communicate with the controller of the concrete vibrator. The remote device may monitor the speed output by the motor and the voltage supplied to the motor to achieve a set speed via the controller, and display information representative of the motor speed and motor voltage to the user. Moreover, the speed output by the motor may be controlled using voltage supplied to the motor.

A remote controlled vibration imparting device for a concrete finishing tool includes a case that attaches to a float using standard bolt layouts. A motor housing is suspended in and attached to the case, and the motor housing partly surrounds a vibrator with a support, a rotor with a shaft and weighted body, a bi-directional motor, and a coupler between the shaft and the motor. Also in the case are a variable speed controller and a remote switch, both of which are electrically connected to the motor and a battery located on or in the case. The case further includes a removable lid that attaches to a concrete finishing tool.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

A backpack device having a harness unit and a battery pack receptacle for receiving a battery pack for supplying a hand-held concrete vibrator with energy, wherein the concrete vibrator has an elastically deformable protective hose, and wherein the backpack device has a hose guide via which the protective hose can be guided with a load-transferring effect over a shoulder of a user of the backpack device.

A vibrating screed comprising a screed member, a motor, and an exciter assembly configured to vibrate the screed member in response to receiving torque from the motor via a driveshaft. The exciter assembly includes a first eccentric mass fixed on the driveshaft and a second eccentric mass axially and rotationally moveable along the driveshaft between a first position and a second position in which the second eccentric mass is axially closer to the first eccentric mass than in the first position. The vibrating screed further comprises a mode selection member to switch the exciter assembly between a first, low vibration mode, in which the second eccentric mass is in the first position, and a second, high vibration mode, in which the second eccentric mass is in the second position.

The present disclosure relates to systems and methods for additive manufacturing of objects by molding or casting materials using a dynamically configurable form. A head for dispensing material includes an adjustable form configurable to define a forming chamber into which the material is dispensed. A method for additive manufacturing includes moving the head to a plurality of positions corresponding to a plurality of dispense locations in a build volume, configuring the adjustable form to shape the forming chamber for each of the plurality of dispense locations; and casting a three-dimensional object. Casting the three-dimensional object comprises dispensing a portion of the material into the forming chamber at each of the plurality of dispense locations.
