The present technology relates generally to a platform and concrete composite slab system used as a building material. A platform, is formed from joined, substantially coplanar boards with connector plates partially embedded between the boards such that a portion of the connector plates extend above the platform's top surface. A reinforcing material (e.g., wire mesh and/or rebar) can be arranged on the prongs or other portion of the connector plates spaced above the platform and concrete is poured over the reinforcing material and allowed to cure, forming a reinforced concrete layer that encases the connector plates and reinforcing material. The connector plates act as standoffs and help to suspend the reinforcing material in the middle of the concrete layer to increase the strength of the reinforced concrete and to fixedly anchor and bind the concrete layer to the platform, so as to establish a composite action between the platform and the concrete.

The present invention relates to a precast concrete member using a PC member, which comprises a prefabricated plate and fixing channels, and is used as a linear member for a column which is an axial force member, as a planar member for a wall which is an axial force member, or as a linear member for a beam or a girder which is a flexural member. A preferred embodiment of the present invention provides a premade precast concrete member having a PC body formed at a predetermined length and multiple steel reinforcements embedded within the PC body along the longitudinal direction, the precast concrete member comprising: a plate assembly in which a pair of board-like plates having a pair of coupling holes formed to be penetrated at a regular interval are formed so as to be spaced apart from each other and to face each other, or two pairs of board-like plates are spaced apart from each other so as to face each other, with one end of each thereof being embedded into one or both longitudinal ends of the PC body, and the other ends thereof protruding, wherein the plate assembly comprises a connecting member of which a part embedded into the PC body of the plate is welded to one side of the steel reinforcement, and both ends are respectively bolt-coupled to the coupling holes of a pair of plates so as to connect a part embedded into the PC body of a pair of facing plates; and fixing channels which comprise a U-shaped channel having an opening formed on the top thereof and multiple anchor bodies coupled to the rear surface of the U-shaped channel, the opening of the U-shaped channel comprising a rib which is formed to be bent inwardly, wherein at least two rows of fixing channels are embedded at regular intervals into one side surface of the width direction of the PC body or into at least one pair of corresponding surfaces of the width direction of the PC body.

The present disclosure relates generally to a precast wall having increased pouring resistance. The precast wall has a configuration by which resistance to the pouring pressure of concrete poured between outer and inner panels is increased, the configuration including rail members buried in outer and inner panels, link members disposed between connection members connecting the rail members in the outer and inner panels to act integrally, and coupling members.

A vertically adjustable steel reinforcing assembly, especially adapted for effective use with dapped beam ends. The reinforcing assembly includes an upper assembly and a lower assembly. Running vertically through the center of each of the assemblies are aligning pin holes. Assembly is configured at the time of casting to accommodate most recent dap design.

A pit for containing a vehicle lifting apparatus is constructed from a plurality of precast concrete pieces and assembled in a trench. Conduit, plumbing, heating elements, and the like are cast into the pieces to facilitate safe construction/assembly of the pit. A lift apparatus is assembled or positioned in and at least partly attached to the pit. One or more mounting features are cast into and/or attached to the pit wall to help fix the lifting apparatus relative to the pit and/or to help fix the pit relative to a surrounding building.

An apparatus, such as a beam pocket, connects a beam to a wall, such as a concrete wall. The apparatus includes a frame having a plurality of panels that cooperate to define a pocket of various heights. The apparatus includes a clamp within the pocket. The clamp is configured to secure an end of the beam at a position within the pocket. The clamp is further configured to selectively define the position relative to the frame. The apparatus further includes at least one anchor extending from the clamp and away from the pocket for mounting with the wall.

A radiation shielding block for constructing structural walls having flat opposed front and rear surfaces defining a thickness of the block, continuously curved, sinusoidal opposed left and right surfaces and top and bottom surfaces. The continuously curved, sinusoidal surfaces have a regular repeating wavelength pattern having a wave direction that is perpendicular to the flat front and rear surfaces, and a length that is two complete wavelengths of a sinusoidal wave. A plurality of the radiation shielding blocks are stackable in a staggered wythe construction having a plurality of wythes and at least one successive course of blocks set atop a previous course of blocks such that the continuously curved, sinusoidal surfaces of the successive course of blocks engage complementary continuously curved, sinusoidal surfaces of the previous course of blocks, and the successive course of blocks is offset by one wavelength from the previous course in a front-rear direction.
