A system, method and apparatus include generating a building model of a building to be constructed at a construction site, identifying within the building model positional locations for installation of one or more anchor apparatuses within structural elements of the building model, transmitting the building model to a portable computing device at the construction site and identifying the location of the portable computing device to a given positional location. At least the generating, identifying, transmitting and identifying steps are implemented via at least one processing device comprising a processor and a memory.

A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

Provided are a hollow composite beam using a dual-web and a construction method thereof. The hollow composite beam using a dual-web can secure space efficiency using a tendon installed in an internal space of a dual-web and can efficiently adjust a tensioning force using the tendon anchored by an anchoring wedge and a separable bolt, wherein the dual-web is formed as a web of a steel beam having a bottom flange on which a deck plate is supported.

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

A system can tension a cable that is to be strung through a plurality of columns. The tensioning system is disposed at the last column and includes a spacing device and a barrel with a tapered cavity. A number of tapered elements are slidably mounted in the barrel's cavity and will encompass the cable and favor unidirectional movement of the cable. The barrel and the tapered elements have opposite openings that allow the cable to emerge from opposite ends thereof. With the barrel at the outward side of the last one of the plurality of columns, the cable is pulled through the tapered elements, away from the plurality of columns. Next, at a side opposite the outward side of the last column, the cable is grasped and pulled away from the barrel to seat the tapered elements. Working again on the outward side, the barrel is then moved away from the last column. The spacing device is applied at the barrel to set the spacing between the barrel and the last column.

A system and method of retroactively reinforcing an exterior wall of a building. An anchoring assembly is mounted into the void space between a first joist and a second joist inside the building. The anchoring assembly has a first element that mounts to the first joist and a second element that mounts to the second joist. The anchoring assembly has an adjustable length. In this manner, the anchoring assembly can be adjusted to properly fit the void space between the first joist and the second joist. An anchor plate is provided outside the building in the area of the wall that needs to be reinforced. A tensioning tether is provided that extends through the exterior wall and mechanically joins the anchoring assembly to the anchor plate. The tensioning tether can be selectively tightened, therein biasing the anchor plate outside the building toward the anchoring assembly inside the building.

A post-tensioning anchor is configured to post-tension at least one tension steel element. The post-tensioning anchor includes a force transfer unit configured to transmit prestressing force into a surrounding concrete substrate and at least one steel member configured to resist an anchoring force by the at least one tension steel element on the force transfer unit. The force transfer unit is made of concrete.

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

A system, method and apparatus include generating a building model of a building to be constructed at a construction site, identifying within the building model positional locations for installation of one or more anchor apparatuses within structural elements of the building model, transmitting the building model to a portable computing device at the construction site and identifying the location of the portable computing device to a given positional location. At least the generating, identifying, transmitting and identifying steps are implemented via at least one processing device comprising a processor and a memory.
