A plurality of the forms can be affixed to a mold decking in a desired arrangement using anchors installed therebetween to form a mold that is reusable to produce multiple waffle panels.

A barrier system is used to block a travel path. The barriers block and direct paths of vehicular and pedestrian travel. 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.

Tooling assemblies and methods for using a tooling assembly to shape an article are provided. For example, a tooling assembly has a forward end and an aft end and comprises a first tool segment, a second tool segment, a forward cam portion near the forward end, and an aft cam portion near the aft end. The forward cam portion defines a follower surface, and at least a portion of the follower surface has a curvilinear profile. The aft cam portion defines a first surface extending at a first angle and a second surface extending at a second angle. The first and second tool segments define a cavity for shaping an article. An exemplary method comprises positioning an article preform within the cavity and inserting a fastener within the aft end of the tooling assembly until the fastener is fully inserted within the tooling assembly.

A concrete structure forming device, comprising: a frame assembly, comprising; a cross member having a first end and a second end, wherein the cross member at least one first connector positioned on a top side of the cross member, a first receiver connected to the first end of the cross member, wherein the first receiver is designed to receive a form, and a second receiver connected to the second end of the cross member, wherein the second receiver is designed to receive a form and is substantially parallel with the first bracket; and a hook, comprising; a handle, wherein the handle has a second connector designed to connect with the first connector of the cross member, and a hook extending from the handle in a predetermined direction relative to the handle, wherein the hook is designed to receive a reinforcement member.

The present disclosure is related to a mold device for molding a waffle slab, wherein a plurality of connecting structures made of steel bars protrude from the sides of the waffle slab, the mold device comprising: a plurality of steel molds provided at both sides of each of the plurality of connecting structures and surrounding the waffle slab, each of the plurality of steel molds having a top surface, which has a hole therein; a plurality of auxiliary devices respectively disposed at the sides of the waffle slab and having through holes corresponding to holes in the plurality of steel molds; and a plurality of fasteners; wherein the plurality of fasteners respectively pass through the through holes of the plurality of auxiliary devices and are fixed into the holes of the plurality of steel molds so that each of the plurality of auxiliary device transversely connects the top surfaces of the plurality of steel molds.

Wall block (2) made of artificial stone material; it has an overall elongate form and a first seating surface (10); an opposing second seating face (12); a first end face (14); an opposing second end face (16); a first wall surface side (18); an opposing second wall surface side (20); it has, on its first seating face, a first seating surface (4) and, on its second seating face, a second seating surface (6); it has a lateral surface (8) and a plurality of extension arrangements (30) arranged in a row on its first seating face (10) and a plurality of receiving arrangements (40) arranged in a row on its second seating face (12), these arrangements each being complementary to one another such that a particular extension arrangement fits in form-fitting engagement with a particular receiving arrangement of a third further wall block which is designed as a receiving arrangement of the claimed wall block, and such that a particular receiving arrangement fits in form-fitting engagement with a particular extension arrangement of a fourth further wall block which is designed as an extension arrangement of the claimed wall block, the particular extension arrangement and the particular receiving arrangement being designed such that the form-fitting engagementconsidered per seis possible both when the longitudinal central axes of the claimed wall block and of the third further or fourth further wall block are parallel to one another and when the longitudinal central axes of the claimed wall block and of the third further or fourth further wall blockseen in plan view of the first seating face or the second seating face of the claimed wall blockextend at an angle (81) to one another; and it is formed having a fin (60) at the transition between its first end face and its first wall surface side, and/or at the transition between its first end face and its second wall surface side, which fin protrudes beyond a virtual flat surface (61) located at the center of the first end face at a right angle to the longitudinal axis of the wall block.

Systems, methods, and articles of manufacture provide for a mold system for molding structures (e.g., sand castles) from one or more various types of molding substances (e.g., sand, clay, snow). In one embodiment, a mold system comprises a split mold comprising at least two mold sections. In one embodiment, a modular mold system allows for different types of mold sections with corresponding joining elements to be joined together to create forms for molding various types of structures. In some embodiments, mold sections are configured to facilitate the breaking of a vacuum created when molding substances are packed into the mold system, thus making it easier to separate a mold from the formed structure.

A bulkhead system for a concrete casting bed includes a pair of base track members spaced apart from one another along a longitudinal direction and a pair of form walls each removably attached to one of the base track members. Each of the form walls has a lower end abutting one of the base track members and an upper end opposite the lower end in a vertical direction perpendicular to the longitudinal direction. Each of the form walls has a tendon slot extending into the form wall in the vertical direction from at least one of the upper end and the lower end. The tendon slot receives a tendon extending in the longitudinal direction.

Molding equipment comprising a mold having at least one cavity is disclosed. Each cavity allows the formation of a brick. A brick molding element is installed on top of each cavity to allow the formation of a mortise interlock element. The brick molding element is typically secured in place by mean of a securing mechanism. The molding equipment may be used for molding a variety of inter-engaging stackable brick element.
