Systems and methods for a concrete apparatus with incorporated lifter are provided. A concrete apparatus is formed by placing a reinforcement system in a mold. The reinforcement system comprises a lifter. Concrete is poured into the mold such that the lifter protrudes from the poured concrete. After the concrete has hardened and the mold is removed, the lifter is used to carry and position the concrete apparatus. After the concrete apparatus is positioned, the lifter is removed at the circumference of the concrete apparatus leaving no holes, thereby eliminating water leakage due to lifting methods.

A building container outrigger to provide an elevated work space for use between concrete slabs of a building under construction having a container, a plurality of support beams, each support beam positioned lengthwise under the floor of the container and extend therefrom the sides, a pair of spaced apart outrigger beams, a first outrigger end and a second outrigger end, each second outrigger end in contact with and affixed to the upper side of each support beam end, the other outrigger beam end removeably anchored to the slab floor with the front edge of the container flush with the exterior or front slab edge, and, thus, functions to functions to efficiently move materials and tools or personnel space from floor to floor as construction phases move vertically.

Improved tilt-up and precast construction panels and improved methods for creating the same address deficiencies in the current tilt-up and precast construction panels. Improved tilt-up and precast construction panels use less concrete and less steel reinforcement and weigh less than current tilt-up and precast construction panels. Additionally, improved tilt-up and precast construction panels have greater insulative properties (both heat and sound) than do current tilt-up and precast construction panels. Improved tilt-up and precast construction panels require less labor on the construction site, thereby increasing efficiency and profitability of construction crews. Additional advantages of implementations of the invention will become apparent through the following description and by practice of implementations of the invention.

A connection assembly for connecting a bolt to a slab includes a first connection part and a second connection part. The first connection part and the second connection part may be capable of being assembled to the slab in a manner so as to sandwich the slab with a first clamping member of the first connection part and a second clamping member of the second connection part between two opposite surfaces of the slab. The first connection part and the second connection part may be connected in a manner such that a connection between a first hollow-tubular-connecting-structure of the first connection part and a second hollow-tubular-connecting-structure of the second connection part may be within a through-hole in the slab, which extends between the two opposite surfaces of the slab.

A lifting and jacking apparatus including a void former configured for embedment in a concrete slab before pouring of the concrete slab and a lifting bail removably insertable in and securely attachable to the void former. The void former includes a built in jacking screw configured to assist in adjusting the height of the concrete slab.

A transport anchor for double walls, includes a bow-shaped basic body, having an arcuate central portion for suspending slinging components, two anchor legs which emanate from the central portion and extend substantially parallel to one another, and a pressure element which is arranged between the anchor legs. The pressure element is formed from a fibre-plastic composite material and has, at its two ends, end caps which are placed by their open side onto free ends of the cylindrical pressure element and which each have openings through each of which an anchor leg extends.

The present invention discloses a construction method of 3D printing and weaving integrated building, comprising: selecting basic building structural components, using finite element analysis after spatial modeling, and combining stress nephogram to set a discrimination domain value and optimize a structure space, obtaining a structural component skeleton; calculating and analyzing the structural component skeleton, determining a weaving range and weaving density of a wire according to weak areas and sizes under structural stress; and then determining a printing process and weaving process according to the structural component skeleton, the weaving range and the weaving density; preparing 3D printing material; 3D printing a matrix and weaving the wire according to the printing process and weaving process, constructing layer by layer, or printing segments, and then connecting segments by preset tenoning structural sections to form a 3D printing and weaving integrated building. The construction method of the present invention has high toughness, fatigue resistance, longevity and other advantages; so that each part of the building can not only meet the different requirements of structural mechanics, but also can achieve economic beauty and modeling art on the basis of safety and reliability.

A lifting device comprises a main body, a clasping assembly, a first shaft and a second shaft. The main body comprises a first through hole, a second through hole and a third through hole therein. The clasping assembly comprises a closed-loop structure configured to be engaged with the third through hole. The first shaft is adapted to be inserted into the first through hole of the main body, and the second shaft is adapted to be inserted into the second through hole of the main body. The main body comprises positioning slots therein and the first and the second shafts have positioning elements thereon. The positioning slots collaborate with the positioning elements to prevent the first and the second shafts from falling out of the first and the second through holes of the main body.

The system and method for connecting a square concrete-filled steel tubular column to a reinforced concrete footing includes a short steel pipe partially embedded in the footing, the pipe having a top end having flanges extending radially therefrom, the top end extending into a cavity in the footing having an elliptical top opening and circular base, the flanges extending above the base. An elliptical base plate is welded to the bottom of the tubular steel column, the base plate having a circular opening defined therein and a plurality of spaced flange slots depending therefrom. The bottom end of the column is lowered into the cavity, the elliptical base plate passing through the elliptical opening in the cavity, and the column is rotated 90° to interlock the flanges with the flange slots. The cavity is filled with concrete grout, and the square or rectangular steel column is filled with concrete.
