The disclosure relates to formwork for producing a concrete element, in particular a wall element or ceiling element, having an opening, in particular a window opening or door opening, the formwork comprising: a formwork panel; opening formwork, which has a frame element for delimiting a portion of the opening, a support bracket for supporting the frame element, and a mounting element for mounting the support bracket; a formwork-stripping device for transferring the opening formwork from a formwork position for the formation of the opening into a formwork-stripping position for the release of the concrete element, wherein the formwork-stripping device has a sliding and tilting mechanism for sliding the frame element in a direction parallel to the formwork panel and for tilting the frame element about a pivot axis running substantially parallel to the formwork panel.

A manufacturing method of a concrete pile is shown. The method includes the following, that is, pouring concrete in the pile molding space, reducing the pile molding space to compress and mold the concrete, draining water drained from the concrete by compression and molding outside of the formwork from the drainage hole, and holding the concrete a predetermined amount of time to harden the concrete. The formwork includes an outer formwork that molds an outer wall surface of the concrete pile, an inner formwork that molds an inner wall surface of a hollow space of the concrete pile, and a pair of end formwork that mold upper and lower end surfaces of the concrete pile. The drainage hole is a gap between adjacent components when the mold is tightened, and the gap is configured to be capable of being opened larger during cleaning than when the mold is tightened.

A 3D printer including a support structure, a lifting mechanism, an adjusting mechanism, a moving mechanism and a printing component. The 3D printer is specifically suitable for 3D printing of buildings or other structures in the field of construction. The adjusting mechanism and the lifting mechanism are arranged below the support structure. The lifting mechanism moves the support structure up and down in the vertical direction. The adjusting mechanism moves the support structure in the horizontal direction. The printing component is arranged on the moving mechanism. The moving mechanism is arranged on the support structure in such fashion that it is movable up and down in the vertical direction.

What is provided is a precast hollow block, a precast wall system incorporating the precast hollow block, and forms for manufacturing a hollow block and a coping cap. Accordingly, the precast hollow block and its incorporation into a precast wall system provide solutions to current “level up” block coping techniques, wall flood protection, wall force protection, and the like. Instead of having mismatched or missing face textures on sloped portions of the wall, the precast wall system allows for easier installation of face-textured blocks directly at the top of the wall. As a result, the precast wall system may readily account for slope transitions of a wall, conform to specific Department of Transportation project requirements, accommodate existing wall construction specifications, and be easily customizable for a variety of applications.

A simulated stone or brick column or retaining wall is made up of rows of masonry blocks of generally trapezoidal configuration arranged in end-to-end relation to one another in each row, each block including a recessed portion being aligned with one another in each row and each block having textured wall surfaces simulating the appearance of brick or stone along one or more wall surfaces arranged in different configurations without the necessity of interlocking the blocks together.

The invention relates to formwork for producing concrete tubbing (500) for a tunnel lining system, with a concrete tub to receive a volume of concrete required to produce the tubbing and, if necessary, to receive the intended reinforcement for the concrete tubbing (500), wherein the concrete tub has at least one base and walls (14, 15) on the base adapted to the mould, wherein at least one wall is arranged detachably from the base and can be pivoted relative to the base between a closed position and an opened position. According to the invention, the formwork has at least one drive system for pivoting the at least one wall between the open and the closed position and for holding same in the relevant position, and the drive system has at least one actuator for pivoting the at least one wall between the open and the closed position.

A mold frame for the production of molded pieces, comprising at least one mold cavity, the at least one mold cavity being defined by a plurality of mold walls, wherein at least one mold wall of the mold cavity is a mold wall that is displaceably attached to the mold frame, and comprising at least one heating element for heating at least a part of the mold frame.

A modular assembly is provided for managing the flow of fluid beneath a ground surface. The assembly can feature a plurality of modules, each having a deck portion and opposing sidewalls extending downward therefrom. The opposing sidewalls can slope outward and away from one another as they extend downward from the deck portion. The modules further comprise a shoulder for supporting a link slab, and to support and separate modules that are stacked during transportation or storage. The sidewalls can define an interior fluid passageway having a flared configuration from top to bottom. The link slab and sidewalls of adjacent modules can define an exterior fluid passageway in fluid communication with a lateral fluid channel. A method is also provided for making a precast concrete module for use in the modular assembly.

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.
