A wall lift mount apparatus is provided for an easier and more efficient construction and erection of a wall in a building structure. Also provided is a method of constructing and erecting a wall using such a wall lift mount.

The method for pouring concrete around a window frame begins by spraying a flat surface with a release, followed by positioning window assemblies on the flat surface. The window assemblies include at least a frame, and also possibly a sash, glazing and removable bracing. The window assemblies are secured to the flat surface and then concrete is poured around the window assembly to form a wall. Once the concrete cures around the frame, the bracing is removed, and the wall is tilted/lifted to a vertical position.

A screeding machine includes a base unit positionable at framework that defines a concrete structure and a screed head assembly movably mounted at the base via an extendable and retractable mechanism. The screed head assembly includes a grade establishing member, a vibrating member, and elevation actuators for adjusting elevation of the screed head assembly. The screed head assembly is positioned at a screeding location via extension of the extendable and retractable mechanism and is movable over the uncured concrete in a screeding direction via retraction of the extendable and retractable mechanism. Adjustable wings disposed at and in front of the grade establishing member in the screeding direction are movable along the grade establishing member. When one of the ends of the screed head assembly is positioned at a frame portion, the wing at that end of the screed head assembly is moved to position the wing at the frame portion.

A method of repairing a tilt wall construction includes affixing a fixture at a bottom of the wall, installing a piling into the earth directly below the fixture, forming a support member having a link corresponding to a distance between the fixture and a head the piling, and affixing the support member to the fixture and to the head such that the piling supports the wall. The fixture is an angle member that is anchored to the wall. A plate is affixed onto a top surface of the head of the piling. The support member can include a pair of steel pipes that are welded at one end to the plate and an opposite end welded to the angle member.

The disclosed technology includes techniques for erecting a wall panel without wasting valuable floor area for wall panel bracing and erecting the wall panel from within the boundary of the land parcel on which the wall panel is being erected. A support structure that is configured to both maintain a prestressed concrete wall panel in a generally vertical position and to provide storage space can be anchored to a floor slab. The wall panel can be lifted from within the land parcel and positioned between the support structure and the boundary of the land parcel. The wall panel can then be anchored to the support structure.

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 portable building, the portable building including: a body having at least one wall that is adapted to move from a substantially vertical position to a second position; and at least one slideout portion that slides outwardly from the body. The body is substantially the size of an ISO shipping container in a transport configuration.

A method for installing a truss-wall stud unit includes coupling a set of bottom plates with a foundation, coupling a set of hinge brackets with the set of bottom plates, coupling a first partial truss with a second partial truss to form a truss-wall stud unit, coupling the truss-wall stud unit with the bottom plates and hinge brackets, and hoisting the truss-wall stud unit into a substantially vertical position. A system includes truss-wall stud units which are connected to bottom plates using hinge brackets. Once connected to the hinge brackets and bottom plates, the truss-wall stud units are hoisted upright into a substantially vertical position using a cable system with a cable support system. Temporary interlocking spacer bars are used to brace the truss-wall stud units at predetermined intervals.
