A prefabricated stair modular assembly mold comprises a base, a step standard module, an upside module of a lower platform, an underside rotating module of a lower platform, an upside module of an upper platform, an underside rotating module of an upper platform, an underside common module, and an underside adjustment modules. Prefabricated stair molds of different dimensions are formed by means of locating holes provided in the assembling modules, and are then fixed by means of sliding holes at two ends. Further disclosed is a mounting method for said assembly mold. Said assembly mold has high positioning accuracy, and small accumulated error, improving the mounting efficiency of the prefabricated staircase mold.

Concrete product machine apron gap adjustment by actuating a gapper mechanism to set a desired gap between a reciprocally-movable apron plate and an interchangeably installable mold assembly installed in a concrete products machine. The gapper mechanism sets a desired gap between the machine apron plate and the mold assembly by injecting an index amount of hydraulic fluid into fluid communication with the rod side of a primary apron plate positioning cylinder, causing the machine's apron plate to retreat a desired gap distance away from an engaged position against the mold assembly.

An upright concrete wall panel form apparatus includes a back panel form to be secured to a base in an upright position, an adjustable support assembly to be secured to the base adjacent the back panel form, and a movable front panel form supported by the adjustable support assembly in an upright position. The movable front panel form is moveable via the adjustable support assembly between a concrete wall panel prep area position and a concrete wall panel forming position. The movable front panel form is aligned with the back panel form in the concrete wall panel forming position so as to define a gap therebetween to receive concrete for forming at least one concrete wall panel in an upright position.

A mold system for a modular telescoping barrier and method of construction provides barriers arranged in a telescoping configuration with tight tolerances. The barriers are constructed with an inner and outer mold subassembly, separated by a gap. A shape-adapted funnel pours mold filling into gap between mold subassemblies. When mold filling dries, the mold subassemblies are removed to access a barrier. Barriers are nested with other barriers having incrementally larger or smaller perimeters to achieve telescoping configuration. A base barrier with a support flange supports multiple barriers. The inner and outer subassemblies are made up of individual panels fitted together end to end, and at corners in a tight relationship. Reinforcing structures abut the panels to prevent panels from bulging. The narrow end of the funnels includes clamps that press inwardly on the panels to prevent bulging. A level and an agitating mechanism enable mold filling to be poured uniformly.

A formwork assembly includes a base body to be fastened detachably to the formwork surface, and an attachment element. A fastening device can release the at least one attachment element, in particular automatically, from the at least one base body. At least one centering device is provided separate from the at least one fastening device, by which the attachment element when fixed to the base body can be automatically aligned relative to the base body. The base body and the attachment element can be arranged, in the fixed state, together on the formwork surface and can be removed from the formwork surface.
