This technology comprises a combined accessory of an in-situ concrete 3-D printed horizontal load-bearing member and a preparation method. The combined accessory includes 3-D printed concrete and a bottom mesh, the 3-D printed concrete contains fine aggregates having the particle size of 0.08 mm-4.75 mm, and the fluidity of the 3-D printed concrete is larger than or equal to 110 mm and smaller than or equal to 190 mm; the bottom mesh is a reinforcing mesh or expanded metal, the diameter of the reinforcing bar is larger than or equal to 0.5 mm, and the mesh aperture of the reinforcing mesh is smaller than or equal to 7.5 times of an upper limit of the particle size of the fine aggregate and is larger than or equal to 7.5 times of a lower limit of the particle size of the fine aggregate.

A foundation having a central vertical pedestal, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal and ribs forming a continuous monolithic structure. An anchoring system under the ribs with anchoring the foundation to the ground by anchoring elements connected to rock anchors, soil anchors, piles or the like. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

A lattice structure is composed of intersecting longitudinal elements and transverse elements, e.g. wires, strands, ropes, rods and/or profiles, with intersection points allocated to the longitudinal elements and transverse elements.

The longitudinal elements and transverse elements, extending in unifold and/or multifold fashion, are connected to one another at least in the intersection points, in particular via twisting, passing into one another and/or knotting with one another.

A process for controlling the embedding depth of reinforcing mesh to a cementitious board is disclosed. The process comprises applying a pressure from a plate to a reinforcing mesh on a core mix moving downstream on a conveyor, wherein the plate vibrates at a rate that assists in embedding the reinforcing mesh at a depth within the core mix such that the reinforcing mesh is barely visible.

A prong is configured for use with a concrete reinforcement element and includes first and second legs positioned opposite first and second sides of the prong and a bridge portion connecting distal ends the legs, where the bridge portion forms a first end of the prong. The legs extend from the bridge portion to a second end of the prong opposite the first end, and each of the legs has a proximal end at the second end of the prong. The proximal end of the first leg is bent toward the second leg, and the proximal end of the second leg is bent toward the first leg, such that the proximal ends of the legs overlap each other. Inner surfaces of the proximal ends of the legs define engagement surfaces configured to engage a tie wire, enabling the proximal ends to be connected to the tie wire.

A fixture for setting rebar at a predetermined distance from the rim of an excavated pit includes elongated first and second legs each having a proximal end and a distal end, the first and second legs rigidly joined at their mutual proximal ends to form an L-shape; an angle adjustment device carried by the first leg, comprising a foot movable towards or away from the first leg along an axis generally parallel to the second leg; a support bracket carried by the first leg at a predetermined offset distance from the proximal end thereof; and a hook extending from the distal end of the second leg, generally parallel to the first leg.

A panel includes structural studs, each of the structural studs includes a central longitudinal axis, a baseplate, and a sidewall extending from the baseplate, and tabs punched out of the sidewall, each of the tabs including a tab leg that is connected to the sidewall at one end of the tab leg, and that projects outwardly from the sidewall, and a tab foot extending from the tab leg and curving in a direction that is toward a plane extending perpendicular to the central longitudinal axis through the one end of the tab leg, and away from a hole in the sidewall created by the tab being punched out of the sidewall, wherein the hole is defined by a base side and a top side, the base side has a greater length than the top side, and the tab leg the extends from the base side.
