A method of fabricating panels includes providing an insert having an interior portion with a top portion and a positioning stop opposite the top portion, and an exterior portion including a fastener hem. Further, the method includes placing the insert in a mold such that only the fastener hem and the positioning stop contact the mold and centering the insert in the mold with the top portion and the positioning stop. The method also includes filling the mold with a casting material such that the interior portion is submerged in the casting material including the top portion, but some of the positioning stop is not submerged in the casting material, curing the casting material to form a panel on the insert, and removing the panel form the mold.

The invention relates to a method for producing a concrete workpiece (1, 60), wherein fresh concrete is poured into a negative (35, 80) of the workpiece (1, 60), and the concrete at least partly hardens in the negative and is then removed. The invention is characterized in that a positive (5, 71) is produced from me concrete workpiece (1, 60) to be produced, the positive is arranged in a casting formwork (20, 70), and negative fresh concrete is then poured onto the positive. The negative fresh concrete is removed after being at least partly hardened (35, 80), and the concrete body produced in this manner is used as a negative (35, 80) in order to produce the workpiece (1, 60) therein using the fresh concrete poured into the negative (35, 80).

Disclosed is a method for producing a plate, wherein liquid, ultra-high-strength concrete is introduced into a formwork, which delimits a cavity, the cavity consisting of a first, flat region and a second, flat region adjoining the first region, the first and second regions having the same depth and being inclined with respect to one another at a bend angle of 120° to 170°. The concrete is introduced, in particular pumped, into the formwork from the bottom, rises in the formwork and hardens in the formwork in the shape of a bent plate.

A method for manufacturing a curable light-conducting body (21) in a casting method, in particular for the manufacture of light-conducting bodies (21) of a curable concrete material (36, 56), wherein a light-conducting mat (1) is embedded in a curable casting material (36, 56), and a casting mold (27) with a recessed mold cavity (18) open at the top is filled with the not-yet-cured casting material (36, 56), wherein, in a first method step, a plurality of molding punches (32) moveably arranged in the mold cavity (18) of the casting mold (27) are moved to at least the plane of the upper edge (43) of the mold cavity (18), 1. in a second method step, the space between the molding punches (32) in the mold cavity (18) is filled with a curable casting material (36), 2. in a fifth method step, the light-conducting mat (1) to be embedded in the casting material (36, 56) is placed on the end sides (61) of the molding punches (32) raised in the mold cavity (18), 3. and that, in a sixth method step, the light-conducting mat (1) is pressed into the casting material (36, 56) wherein, with the pressing movement of the light-conducting mat (1) into the casting material (36, 56), the molding punches (32) are approximately synchronously moved downwards out of the bottom surface of the mold cavity (18).

A weldment support for holding a weldment plate in a precast concrete form is provided. The weldment support holds the weldment plate at a predetermined position so that the weldment plate is exposed on one side of the finished precast concrete panel. Weldment plates have one or more studs extending into the form to anchor the plate in the precast concrete panel. The weldment support has multiple adjustment features to secure the weldment support to different sizes of studs and to set the weldment plate at different positions within the form. In some embodiments, one adjustment feature is a plurality of deflectable fingers that engage the stud of the weldment plate, and another adjustment feature is a plurality of segments that can be broken off of the support to set the position of the weldment plate in the form.

The present invention pertains to integrated machine for manufacturing anchor embedded cladding elements. Essentially, this machine comprises a cladding block manufacturing machine and anchor feeding and embedding machine, where the concrete block manufacturing machine and anchor feeding and embedding machine are configured for coordinated operation for producing anchors embedded cladding elements comprising concrete blocks and anchors embedded within said blocks. The flexibility and versatility of the machine is in determining the end location of the anchors in the final cladding elements before even manufacturing the cladding blocks. This provides greater degree of freedom, which in turn allows increasing the strength in fixing the cladding elements to a support wall on the one hand, and decreasing onsite or prefabrication workload and difficulties in the cladding process.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

Disclosed is a luminescent insert capable of being included in a construction element, including a transparent or translucent solid matrix, and at least one luminescent material dispersed in the solid matrix, the insert defining an outer surface. The luminescent material is a colored luminescent composite pigment, made up of at least one luminescent pigment and at least one dye. Also disclosed is a construction element including at least one such luminescent insert.
