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.

The disclosure presents a composite column formwork which utilizes a fiber reinforced polymer (FRP) stay in place container which incorporates horizontally coplanar support chairs bonded to the interior surface, closed ties bonded to the support chairs and a plurality of longitudinal rebar enforcements bonded to the closed ties. All of the components in a preferred embodiment are formed of a fiberglass material.

The disclosure presents a composite concrete structure formwork which comprises stay in place fiberglass profiles and reinforcement to form various building and shelter structures. The structures include an interior container maintained at a set distance within an exterior container to form a void. The void is filled with wet concrete which is allowed to cure. All of the components in a preferred embodiment are formed of a fiberglass material.

The disclosure presents a composite conduit formwork structure which includes a cylindrical outer casing adapted to bond with a cylindrical inner casing which are maintained at a fixed distance apart by a plurality of radial stanchions. The inner casing and outer casing form an interior void which is filled with concrete during manufacture. The outer casing and inner casing remain in place to protect the structure once completed. A novel method of assembly is also provided whereby radial stanchions are rotated between the outer casing and inner casing. All of the components in a preferred embodiment are formed of a fiberglass material.

The invention relates to a system with markers for placing a retaining pile with asymmetrical reinforcement and method for using same, so that the reinforcement is disposed in the correct position. The system comprises at least one positioned separator and a marker-separator attached to transverse reinforcing means, at least one marker disposed on a guide wall or sleeve, the marker-separator being aligned with the marker or separated by a distance equal to or less than a predetermined safety value. The method for using the system comprises the steps of: positioning a separator and attaching a marker-separator to the transverse reinforcing means, positioning the marker on the guide wall or sleeve; aligning the marker-separator with the marker or positioning at a distance equal to or less than a predetermined safety value, when the asymmetrical reinforcement is placed inside the guide wall or sleeve.

An adjustable concrete reinforcement assembly includes a base member having a pair of open ends and an upper axial cavity defined along the length of the base member. A pair of frame members each include a horizontal extending portion and a vertical extending portion in which the horizontal extending portions are sized to engage the upper axial cavity of the base member. A hanger member is disposed at an upper end of the vertical extending portions of each frame member; wherein the frame members are axially movable within the base member to enable a horizontal dimension of the assembly to be selectively adjusted. At least one support is further provided to receive at least one concrete reinforcement member, such as rebar. In at least one version, adjustments can be to the horizontal dimension of the frame and optionally the vertical and horizontal positioning of the hanger members relative to a concrete form.

A plurality of identical slab bolster uppers each include a body with a rebar contact surface separated a height distance from a ground contact surface along a vertical axis. The rebar contact surface extends from a first end to a second end along a horizontal axis. The first end terminates in a planar abutment surface that is one side of a thickness profile, and the second end has a different shape that includes a planar abutment surface, and a snap-fit connector shaped to receive the thickness profile of the first end. Two slab bolster uppers may be moved from a disconnected configuration to a connected configuration exclusively responsive to sliding the planar surfaces along one another while in contact along a vertical axis until the thickness profile of the one slab bolster upper is received in the snap-fit connector on the other slab bolster upper.

The present invention provides a fixture with which a plurality of grids can be definitely constructed in a short period of time even by an inexperienced worker without causing the worker to do heavy work. In substantially center positions in the lengthwise direction of bottom portions of first frame members, a pair of third frame members included in connecting means are provided. In the third frame member, a base portion is caused to stand on a bottom portion of the first frame member. One of arms of a U-shape of the base portion works as a holding portion included in the connecting means, and the end of the holding portion is bent inward of the base portion to form a connection bent portion having a function to engage with a circumferential surface of a vertical wire material or a lateral wire material of a second welded wire mesh, and a function to prevent the vertical wire material or the lateral wire material of the second welded wire mesh from coming off from the connecting means.

A central rod passes through a form-board. A first disc is attached to a first end of the central rod. The first disc abuts to a first side the form-board. A second disc is attached to the central rod between the first end of the central rod and a second end of the central rod. The second disc abut to a second side of the form-board opposite the first side. A third disc, attached the second end of the central rod, is configured to receive a rebar rod.

A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. 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.
