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.

A liner for a form is provided. The form allows for the creation of a precast concrete wall to be formed. The liner allows a building material, for example, brick veneer, to be placed in the liner in a pattern. The pattern may be a soldier course that can formed over openings in the precast concrete wall. When liquid concrete is poured into the mold and then hardens, the concrete holds the building material in place in the pattern produced by the liner.

Detectable warning areas (DWAs) and methods of forming the same are provided. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold. A peg may be inserted into the mixture in the dome-shaped cavity of the die-cast mold. The mixture may be allowed catalyze and harden in the dome-shaped cavity of the die-cast mold, then a molded dome may be removed from the dome-shaped cavity of the die-cast mold. A portion of the molded dome such as the peg may be inserted into a hole in a prepared substrate. The dome may also be prepared by grinding an outer top surface with a drilling attachment. The dome may instead be formed with the use of an insert and a mat template.

A machine (1) for the additive manufacture of a component (2) by complete or partial selective melting of a powder comprises: a working chamber (100); a sleeve (3) having a top opening (4) opening into the working chamber (100), and having a vertical central axis (5), a support plate (6) intended to accept the component (2) in the process of being manufactured, a device (7) for actuating the translational movement of the support plate (6) inside the sleeve (3) along the vertical central axis (5) of the sleeve (3), and a component (2) extraction system (8) comprising a container (9), the extraction system (8) further comprising at least one closure plate (12) that is able to move in order to close the bottom opening (15) of the container (9), and the attachment between the support plate (6) and the actuating device (7) being of the removable type.

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.

In an exemplary embodiment, a system for making tied block mat with a border includes a mold having an array of mold cavities; and a hopper that receives a hardenable paste and is spaced from the mold to receive a sheet of mesh material therebetween, the hopper having an opening for depositing the hardenable paste into selected mold cavities, the hopper forming a filling zone with the mold wherein the hardenable paste flows through the opening into the selected mold cavities, and a blocked zone where the hardenable paste is prevented from entering other selected mold cavities of the mold; whereby the tied block mat is formed wherein the hardenable paste in the selected mold cavities becomes embedded in the sheet of mesh material in the filling zone, and a border is formed in the blocked zone where the hardenable paste is blocked from entering the other selected mold cavities.

The present disclosure relates to a method of forming a waffle slab with concrete surfaces that do not require polishing, the method comprising: providing steel molds connected to each other, and forming a space in the steel molds, wherein at least one of the steel molds has a hole; disposing a plurality of inner molds in the space formed by the steel molds; disposing predetermined steel bar cages between the plurality of inner molds, and between the plurality of inner molds and the steel molds; disposing a steel plate on top surfaces of the steel molds, wherein the steel plate comprises separate air holes; and pouring a Self-Compacting Concrete (SCC) into the space from the hole of the at least one of the steel molds such that the SCC fills the space to form the waffle slab.

A seamless stamp device for impressing configuration into deformable materials includes a recess member having a substantially planar top wall and an undulating bottom wall with a plurality of ridges integrally joined to the bottom wall, the ridges defining a preselected pattern upon the bottom wall. The seamless stamp device further includes a protrusion member having a substantially planar top wall and an undulating bottom wall with a plurality of ridges integrally joined to the bottom wall, the ridges defining a preselected pattern upon the bottom wall. The recess and protrusion members are detachably engaged such that the undulating bottom walls and ridges of the engaged members provide a continuous, seamless design or pattern in the surface of a deformable material when the recess and protrusion members are forcibly inserted into the deformable material, then vertically elevated and vertically lowered and repositioned upon a different portion of the surface of the deformable material. The method repeating until the entire surface of the deformable material has been configured with the designs of the bottom walls and ridges of the recess and protrusion members.

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.
