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 barrier system is used to direct and block a travel path of pedestrians and vehicles. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.

A concrete mold including a mold frame with a frame body and at least two rows of teeth formed on the frame body lying opposite one another and in each case facing a mold insert. The mold insert has an insert body and at least two rows of teeth arranged on the insert body lying opposite one another and in each case facing the mold frame. Recesses are in each case formed on the insert body between teeth of its rows of teeth, in which recesses teeth of the rows of teeth of the frame body in each case engage in the assembled state of the mold. Recesses are in each case formed on the frame body between the teeth of its rows of teeth, in which recesses the teeth of the rows of teeth of the insert body in each case engage in the assembled state of the mold.

A method for attaching a first object to one or more second objects of dissimilar materials, without any bonding material, using a molded attachment block is provided. Anchoring grooves are created and a constrained assembly is positioned at opposing sections on a surface of the first object. A tension is generated in tension bearing members anchored in the anchoring grooves and extended along a length of the constrained assembly. The constrained assembly is constricted between mold side members positioned perpendicular to the mold end members. The tension bearing members are clamped between bolt assemblies. A viscous liquid is poured and cured on the constrained assembly, the tension bearing members, the anchoring grooves, and the bolt assemblies for creating the molded attachment block with opposing ends of the threaded members of the constrained assembly extending outwardly from the molded attachment block for attachment to second objects without any bonding material.

A stacking clip suitable for use with a concrete forming system having one or more frame elements having one or more ribs formed on a rail. The stacking clip allows an extension component to be coupled to the stacking clip and to hence extend the height or the width of the frame element.

A configurable steel form system for creating precast concrete panels is disclosed. The configurable steel form system can be used to create precast panels for both commercial tilt panels and highway noise barrier walls, among other applications. A plurality of steel form system sections are preferably fabricated from steel plate bent into a J-channel member. The configurable steel form system can be designed in sections that are quickly assembled. To suit a particular application, a section can be extended by sequentially attaching extension members to a primary member. A quick-release mechanism can be implemented for ease and speed of connection. Each section can have the panel depth and contour fabricated into the steel form profile. Anchoring holes and corner miters can also be cut into the form's framework.

An adjustable mold capable of making castings of various configuration is provided. The adjustable mold has an adjustable die with a core and an adapter, a protrusion, a cavity, and an outer portion with at least two sidewalls, at least two endwalls, and a base therebetween, which outer portion at least partially surrounds the adjustable die to thereby define a mold. During casting, molding material is poured in the mold and allowed to cure to make a casting. The adapter is replaceable to enable castings of multiple configurations to be cast suing the adjustable mold.

A prefabricated component mold includes a number of side plates and a removable film. The side plates cooperatively define a molding cavity for molding a prefabricated cement component. The removable film is configured to be removably arranged on an inner side of the side plates for preventing the prefabricated cement component from contacting the side plates.

A device for supporting stripper head on a mold box of a concrete product machine mold assembly. The device includes a set of attachment hardware that connects a stand-off leg to a stripper head plate to support the stripper head with the stripper head plungers disposed in respective protected positions within respective plunger receptacles of the mold box. The hardware set comprises a ferrous metal portion configured to be carried by the stripper head plate and a magnetic portion carried by the stand-off leg in a position to magnetically engage the ferrous metal portion and allow for removable attachment of the stand-off leg to the stripper head plate when the ferrous metal portion is carried by the stripper head plate.

Adjustable concrete forms, typically fabricated from steel, allowing variation in the height, tilt, and shape of the form of gravity wall sections. The adjustable concrete form includes adjustable height vertical and sloped walls to change the height of the form through the operation of built-in mechanical jacks, such as ball screw assemblies. The separation distances at top and bottom of the walls can be adjusted by upper connectors (e.g., tie bars) and lower connectors (e.g., base straps). The same adjustable concrete form is assembled, used to pour a gravity wall section, disassembled, repositioned, and reassembled a virtually unlimited number of times to create varying height, tilt, and shape gravity wall sections for mile after of roadway construction.
