A sill plate anchorage assembly for supporting prefabricated building walls includes an elongated member having spaced holes. A concrete formwork defines a space for receiving concrete to form a foundation to support the elongated member. The elongated member may be supported temporarily from the formwork. Anchor shafts extend within each of the spaced holes and extend below the elongated member into the space defined by the concrete formwork. After forming and curing the concrete, nuts or other fasteners are tightened over the upper ends of the anchor shafts to secure the elongated member against the foundation. The upper portions of the spaced holes may include enlarged recesses for receiving the fasteners. Indicia marked upon the elongated member may show the location and type of pass-through regions. A method to secure a horizontal sill plate to an underlying concrete foundation to support vertical building wall panels is also disclosed.

An assembly creates annular voids in concrete around the distal end of cylindrical tubes. A cap has a flat top and a cylindrical, depending skirt. An annular, foam plug extends between the inside of the skirt and the outer diameter of the tube. The plug has an undeformed inner diameter smaller than an outer diameter of the tube to create an interference fit around the tube and keep concrete out when the cap is on the end of the tube. The plug has a radial thickness of 0.3 to 1 inch, and has an axial length of 1 to 3 inches, with a bottom of the plug located at a bottom of the skirt. The cap is glued to the end of the tube for pressure testing. After the tube is entrained in concrete, the cap and plug are removed to leave a void in the concrete surface.

An alignment head for an automatic fastener feed installation tool employs a platform with spring biased retractable pins and a central opening. The retractable pins are spaced to protrude downwardly and engage opposing sides of a support joist. The central opening receives the fastener which is automatically positioned for driving at an entry position into a deck board overlying the joist. The fastener is drivable into the joist at a medial position of the joist and a pre-established position from the edge of a deckboard. The pins also define the spacing of the adjacent deck board. In one embodiment, the alignment head is employed for securing the deck boards at a consistent 45° angle to the joist.

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 system includes a form panel positioning apparatus for positioning an elevated form panel of a concrete form. The apparatus may include at least one positioning subassembly providing positioning of the form panel in at least one direction, and may include a first positioning subassembly with a first clip to clip onto an element of a concrete reinforcement structure, a first support rod engageable with the first clip, and a first positioning plate positionable on the rod adjacent to the form panel to support the form panel on the rod. The system may include a second positioning subassembly for positioning the form panel such that the form panel is supported in two directions, such as substantially vertical and substantially horizontal directions.

A block out chair system that is used to make a block out for a railing or to make a pass-through in a concrete slab. the block out chair system is a circular flat base that defines a circular aperture within the circular flat base, at least three supports that extend perpendicularly outward from the circular flat base, a hollow cylinder that has a perimeter wall that extends linearly outward from the at least three supports, the hollow cylinder defines a plurality of teeth that are configured to secure a foam cylinder, and a solid foam cylinder that is inserted within the hollow cylinder.

An anchor assembly for being embedded in concrete includes a metal plate including an opening, the metal plate including a top surface and bottom surface; the opening including a wall extending from the top surface or the bottom surface; and a threaded rod operably attached to the metal plate.

A form for forming a void or an architectural feature of a predetermined configuration in a moldable forming composition is disclosed. Embodiments of the invention provide an adjustable form body having first and second sides, said form body configurable between a first substantially planar position and a second non-planar position. In some embodiments, the form comprises a surface coating. A form body according to example embodiments of the invention has a plurality of grooves.

A method is defined for attaching mounted parts on a mounting substrate formed of concrete or masonry, having a group of anchors wherein the following is true for the ratio VSd/NSd of the rated value for the transverse load VSd and of the rated value of the tensile load NSd of at least one anchor in the anchor group: VSd/NSd≥0.3, preferably VSd/NSd≥0.6 and particularly preferably VSd/NSd≥1.0, and wherein the characteristic resistances of these anchors to transverse loading VRk or to tensile loading NRk satisfy the following relationship: VRk/NRk≤1.1. The at least one anchor of the anchor group is inclined at an angle αAnker to the perpendicular to the surface of the mounting substrate in such a manner that the following is true: αAnker=k*¾*arc tan (VSd/NSd) for NSd>0, and αAnker=k*67.5° for NSd=0, where: 0.8≤k≤1.34, providing that αAnker≤75°.
