A mortar applicator includes: a duct; a piston movably mounted within the duct, dividing the duct into first and second variable volume chambers; a pump fluidly connected to the first variable volume chamber; a nozzle operatively connected to a first end of the duct to discharge mortar contained in the first variable volume chamber; and a motor operatively connected to the piston. A rack and pinion assembly operatively connects the motor to the piston and includes a rack configured to drive the piston and a pinion connected to the motor. In a discharge mode, the motor drives the rack and pinion assembly, moving the piston to force mortar through the nozzle opening to discharge mortar from the mortar applicator. In a refill mode, the pump fills the first variable volume chamber with mortar, forcing the piston to retract. The rack moves with the piston in the discharge and refill modes.

A mortar applicator includes: a duct having a first end and a second end; a piston movably mounted within the duct, the piston dividing the duct into first and second variable volume chambers on opposite sides of the piston; a piston actuator operatively connected to the piston, the piston actuator being operable to move the piston within the duct; a nozzle assembly located at the first end of the duct, the nozzle assembly having a tip defining a nozzle opening in fluid communication with the first variable volume chamber to discharge mortar contained therein; and a cover member selectively movable between an open position and a closed position to respectively allow and prevent mortar to be discharged through the nozzle opening; a cover member actuator operatively connected to the cover member, the cover member actuator being operable to move the cover member between the open position and the closed position.

A method for assembling a brick pattern for forming a precast brick panel. The method includes conveying bricks in a row to a spacing station, spacing the bricks apart in a row at the spacing station according to a predetermined row pattern and to a predetermined row length by allowing the spacing between adjacent bricks to vary if required. The method then involves transferring the row of spaced bricks onto a generally planar support surface of a brick pattern assembly station. By this method, a plurality of rows of spaced bricks are assembled adjacent each other on the support surface of the brick pattern assembly station to form a brick pattern.

A construction method for protecting a surface of a structure is provided to protect interior and exterior surfaces of the structure before construction starts. The construction method is executed by laying a soft base material on the surfaces of the structure and covering the base material with a quick setting cement material to form a leveled cement plate with great wear resistance and pressure resistance whereby the surfaces are not damaged by any improper force derived from the construction. Thus, the construction efficiency is increased. The base material on which the quick setting cement material is laid can be easily removed from the surfaces of the structure without tools because the base material is not adhered to the surfaces. The base material can also be reused after being separated from the quick setting cement material to prevent the occurrence of environmental pollution and reduce the cost of construction.

A hawk having a first board with an upper surface, an opposing lower surface, and an edge. A handle is attached to the lower surface of the first board, and a hinge is attached to the edge of the first board. A second board with an upper surface is also attached to the hinge. An angle between the first board and the second board can be set as desired by selectively rotating the hinge between the first board and the second board.
