A fire resistant construction block that comprises a core comprising a polygonal shape including a front face, a rear face, a right face, a left face, a bottom face, and a top face. The fire resistant construction block further comprises a fire resistant coating surrounding at least a portion of the core and an optional intermediate layer disposed between the core and the fire resistant coating. The fire resistant construction block can comprise a plurality of channels, and the top face of the fire resistant construction block comprises a sloped surface. The fire resistant construction block can be configured to be disposed above a window of a building and the placement of the fire resistant construction block can enable an exterior wall of a building to comply with a National Fire Protection Agency Code 285 standard fire test method and/or other fire test standards.

A device for day lighting the interior of structure deploys reflective louvers that are spaced apart in stacks. The louvers include a coating or multilayer structure that is operative to reflect visible light but transmit IR light through the louver. The louvers also have a retro-reflective structure to return the IR light by reverse reflection in the opposite direction of the incident light, which is back toward the sun. The interior of the structure is more uniformly illuminated with visible light while the louvers and interior are not heated by IR light or radiation from the sun.

A tower segment, in particular for a tower of a wind turbine, a wind turbine, and a method for manufacturing a tower segment is provided. A tower segment, in particular for a tower of a wind turbine, comprising a casing segment with an inner casing surface, an outer casing surface and a cutout for a door, wherein the inner casing surface has a first inner reinforcing portion and/or the outer casing surface has an outer reinforcing portion, wherein the inner reinforcing portion and/or the outer reinforcing portion adjoin the cutout, and the inner reinforcing portion has an inner reinforcing plate and/or the outer reinforcing portion has an outer reinforcing plate.

In a one aspect there is disclosed a formwork wall panel (10) having an operative inner surface (12) to face towards an inner space to be filed with building material and an opposing operative outer surface (14) having a surface finishing component (16) secured thereto. The operative inner surface (12) of the formwork wall panel (10) includes a brace coupling formation (18) operatively adapted to engage a wall panel coupling formation (20) of a brace (22) operatively extending between the formwork wall panel (10) and an opposing second formwork wall panel.

A drive through bin door having a curved bottom I-beam connected to an inner and outer door frame. The door frames have a curved top member connected to a pair of posts by a plurality of nuts and bolts. A door panel is hingedly connected to one of the door frames.

An extrusion profile and cap system is provided. The extrusion profile may be made of metals, polymers, ceramics, and the like. The extrusion profile may include an outer perimeter forming an internal cavity. At least one channel may be formed along the outer perimeter and protruding into the internal cavity. The cap is releasably attachable to the extrusion profile and may cover at least a portion of the channel. The cap may hide bolts, screws, angle bars, wires and the like within the channel.
