Abstract: A one-piece clip includes a stiffener, a first connector plate extending from the stiffener at a first dihedral angle to the stiffener, the first connector plate configured for attachment to a support member extending beneath a corrugated metal deck, and a second connector plate extending from the stiffener at a second dihedral angle to the stiffener, the second connector plate configured for attachment to an underside of the corrugated metal deck. A method of retrofitting a structure to augment its resistance to uplift and seismic forces includes the steps of attaching a first connector plate of a one-piece clip to a support member extending beneath a corrugated metal deck, and attaching a second connector plate of the one-piece clip to an underside of the corrugated metal deck.

Abstract: A sonic drilling apparatus with adapter for emplacing columns includes a sonic drilling apparatus generating vibrational waves and having a fitting. An adapter is coupled to the fitting for removably attaching a column to the sonic drill apparatus. A centering assembly is positioned below the adaptor for receipt of a column therethrough.

Abstract: A window with display function includes a window frame, a window body embedded in the window frame, a flexible display screen, an electronic element. The window body includes a first glass layer and a second glass layer spaced from each other. The flexible display screen is between the first glass layer and the second glass layer. A house using the window is also related.

Abstract: Disclosed is a system for constructing a habitable room or the like including at least one door, walls, and door mount to pivot relative to the two walls about an axis in such a manner as to be suitable for occupying at least two positions, namely a “closed” position in which the door is contained in the plane of the first wall, and an “open” position in which the door is not. The system includes a through opening and a setback each presenting a shape substantially complementary to the door and made respectively in the first and second walls, and together having a common zone, with the axis in the zone, and arranged in such a manner that, on pivoting about the axis, the door in its first position it is integrated in the opening, and when it is in its second position, it is contained in the setback.

Abstract: A post-tensioned concrete cap foundation has helical anchors with pipes having several helical discs welded around the pipe perimeter to spin drill deep into subsurface soils or other soft materials with holes in the pipe for high pressure-grouting in place. The helical anchor pipes include a tensioning element for pulling and post-tensioning the helical anchor. The helical anchors are tension anchors which can be converted to compression anchors. The helical anchors in tension serve to pull the foundation cap down to compress the underlying soil while the compression anchors limit the maximum settlement of the concrete foundation cap. The foundation also includes perimeter-forming and interior corrugated metal pipes with upper and lower sleeved horizontally extending radial bolts that are secured to the pipes and post-tensioned to provide lateral foundation compression.

Abstract: A quick assembling floor mat has multiple reinforced plastic bars and multiple connecting strips. Each reinforced plastic bar has a body, a mounting seat formed on the top surface of the body, at least one metal reinforcing sheet mounted in the body to enhance the structural strength of the body and two connecting grooves respectively formed in the sidewalls of the body. Each one of the connecting strips is connected to two adjacent reinforced plastic bars and has two enlarged ends respectively formed on and protruding from the sides of the connecting strip and corresponding to the connecting grooves of the two adjacent reinforced plastic bars. The reinforced plastic bars only use a small amount of a metal material to reinforce, and this can reduce the cost of materials and can maintain the rigidity and the intensity of the quick assembling floor mat.

Abstract: Deck planks with undercut side grooves can be attached to underlying joists by hidden fasteners with leading wings and trailing feet engaged into the side grooves of the deck planks. The bodies of the hidden fasteners space the deck planks so as to provide adequate drainage gaps between the top faces of the deck planks. A power driver tool can be used for rapidly positioning the hidden fasteners and for attaching the hidden fasteners to the joists.

Abstract: A building facade including an exterior envelope including facade elements, a rain barrier, profiled holding and supporting elements fixed vertically to floor edges, a thermal insulation system including a first insulating element in front of floor edges and a second insulating element on the inside, between floors, a vapor barrier, and an interior lining. The first insulating element is basically continuous across the surface of the facade, or is essentially free of air pockets, two adjacent breadths of the first insulating element being separated by a flat surface of the profiled elements projecting forwards of the floor edges.
