In embodiments, a flexible mat forming system includes a rotating drum having a plurality of mold cavities; a hopper that receives a hardenable paste and deposits the hardenable paste into the mold cavities as the drum rotates relative to the hopper; and a sheet of mesh material that is fed between the hopper and the mold cavities facing the hopper. The hopper includes a plurality of side walls and a bottom panel having an opening, wherein the plurality of walls and the bottom panel define an interior chamber; and an auger rotatably mounted in the interior chamber and having a plurality of radially extending protrusions along a length thereof, the radially extending protrusions including angled surfaces to displace the material received in the interior chamber along a length of the interior chamber to fall through the opening into the mold cavities.

A method of preparing a woven fabric material for use in a ceramic matrix composite includes passing a desized woven fabric tape having a first inter-filament spacing through a dispersal module configured to transform the desized woven fabric tape into a dispersed woven fabric tape having a second inter-filament spacing greater than the first inter-filament spacing. The dispersal module includes a first charging element with a charged surface and disposed to apply an electric charge to the desized woven fabric tape. The method further includes applying a polymer binder to the dispersed woven fabric tape to create a stabilized woven fabric tape having the second inter-filament spacing.

The present invention is related to translucent building elements, and more specifically to their manufacture. The present invention comprises a method for the manufacture of an insulating core element for a translucent building element, an insulating core element for a translucent building element, a method for the manufacture of a translucent building element, a translucent building element, a method for the manufacture of a translucent building wall, a translucent building wall, and a method for the manufacture of a multiple of stacked rows of elongated light-conducting elements for an insulating core element.

A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

A method for manufacturing a pre-fabricated element for construction and electricity production includes providing a formwork mould; introducing a photovoltaic module into the formwork mould, and for this purpose vertically positioning the photovoltaic module against or in replacement of one of the walls of the formwork mould, the front face of the at least one photovoltaic module being arranged so as to face an area of the space located outside the mould; depositing an adhesive structural material or a mixture of adhesive structural materials on all or part of the rear face of the at least one photovoltaic module arranged so as to face an area of the space located inside the mould, the adhesive structural material including at least one polymer from the epoxide, polyurethane, acrylic, or styrene-acrylic family, and pouring fresh concrete into the formwork mould so as to cover the adhesive structural material.

A reinforcement arrangement and a method for producing a construction material body using the reinforcement arrangement. The reinforcement arrangement comprises a reinforcement body and at least one holding anchor unit. Each holding anchor unit is arranged or attached at the reinforcement body by a foot section. A holding section adjoining the foot section is moveable between a storage position and a function position. In the storage position, the holding section extends directly adjacent along the reinforcement body and abuts the reinforcement body at one or more locations. In the function position, a free end of the holding section opposite the foot section is larger than in the storage position. The holding section can be moved manually or self-acting from the storage position into the function position. The reinforcement body, the holding section, and the foot section are preferably embodied as textile-reinforced elements.

Provided is an apparatus for preparing a building structure with 3D printing, comprising: a 3D printing device (1), having a storage chamber (11) and a printing head (12) connected to the storage chamber (11) and being movable relative to a base frame; and a reinforcing device, movably disposed relative to the base frame, and having a driving mechanism (3) for driving short rebars or short ribs to perform an insertion movement in a direction intersected with a stacking direction of a cement-based slurry layer; the driving mechanism inserts the short rebars or the short ribs into an interlayer interface spanning at least two adjacent cement-based slurry layers printed by the 3D printing device (1). Also provided a method for preparing a building structure with 3D printing. There is no printing gap between the cement-based slurry layer printed by the apparatus and the inserted rebars, ensuring a tight connection between the cement slurry and the rebars, so that the mechanical properties and toughness of the interlayer interface between the cement-based materials of the 3D printing are truly improved.

Couplings for coupling pre-cast construction segments together and pre-cast construction segments having such couplings. A construction coupling for connecting prefabricated segments includes a pair of anchors. Each anchor includes a central portion and a pair of legs. The central portion defines an elongated bore. The pair of legs extending from opposite sides of the central portion. Each leg extending in a direction generally transverse to the elongated bore and having a proximal end attached to the central portion and a free distal portion disposed away from the central portion. The construction coupling also includes a pin adapted to be received in the elongated bores of the pair of the anchors to connect the pair of anchors together.
