A commercial hopper grain bin shell can be assembled on a concrete pad using jacks to successively support previously coupled side-wall panel rings above the concrete pad. The assembled shell can be supported above the concrete pad with the jacks while coupling a horizontal support beam around a bottom of the assembled commercial hopper grain bin shell. An uppermost ring of vertical support legs can be coupled to the horizontal support beam. An uppermost ring of hopper panels can be coupled to the horizontal support beam. The assembled shell and the vertical support legs previously coupled to the horizontal support beam can be successively supported above the concrete pad with jacks while coupling an additional ring of vertical support legs to the bottom of the previously coupled vertical support legs. An additional ring of hopper panels can be successively coupled to the bottom of the previously coupled hopper panels.

Embodiments of a constructions system for constructing a structure atop a foundation are disclosed. In an embodiment, the construction system includes a rail assembly. The rail assembly is configured to be mounted to the foundation. In addition, the construction system includes a gantry movably disposed on the rail assembly. The gantry is configured to translate along a first axis relative to the rail assembly. Further, the construction system includes a printing assembly movably disposed on the gantry. The printing assembly is configured to translate along a second axis relative to the gantry. The second axis is orthogonal to the first axis. The printing assembly is configured to deposit vertically stacked layers of an extrudable building material onto a top surface of the foundation to construct a structure.

A hydraulic expandable connector for taking up a slack in a tie rod in a hold-down system includes an inner cylindrical body disposed within an outer cylindrical body; a first actuation spring operably attached to the inner cylindrical body and the outer cylindrical body to urge relative motion between the inner cylindrical body and the outer cylindrical body such that the connector expands axially to take up the slack; a first chamber and a second chamber disposed between an outer wall surface of the inner cylindrical body and an inner wall surface of the outer cylindrical body; a first passageway communicating between the first chamber and the second chamber; and a valve operably disposed in the first passageway in an open position when the connector expands and a closed position when the connector is subjected to an axial load.

A multi-story building (200) is described for manufactured homes (212) such as container homes. The building (200) includes a ground floor (202), a number of intermediate floors (204), and a top floor (206). The building (200) includes a throughway (208) on the ground floor (202) that allows passage of a transportation vehicle (210) such as a flatbed truck carrying a manufactured home (212). The transportation vehicle (210) can use the throughway (208) to position the manufactured home (212) in alignment with a hoistway (214). A hoist mounted on the roof (216) can then be used to hoist the home (212) to a desired floor (204 or 206).

A shrinkage compensating device for seismic restraint in wood building construction combines a spring-operated take-up device (TUD) with a ratcheting split nut. The split nut, attached to or formed as part of a rotatable component of the TUD, acts as the securing nut for the TUD and allows the TUD with the split nut to be slipped over the top of a threaded rod and pulled down along the rod into place against a structural member. Several forms of attachment of the split nut to the spring-operated TUD are disclosed, as is a simplified rotatable split nut version.

Apparatus, systems, and methods for attaching an assembled wall module to a building structure, according to which a framing section, including a plurality of structural members and a first coupler connected to a first structural member of the plurality of structural members, is connected to the building structure. After connecting the framing section to the building structure, relative movement is permitted, via the first coupler, between the framing section and the building structure in a first direction. Before connecting the framing section to the building structure, a plurality of sheeting sections may be connected to the framing section. The framing section may further include a second coupler; in such instances, after connecting the framing section to the building structure, relative movement is permitted, via the second coupler, between the framing section and the building structure in a second direction, which second direction is the same as the first direction.

An apparatus, system, and method for lifting an assembled wall module into position for attachment to a building structure.

A device that compensates for abrupt variations in fluid flow rate for a pump line is described. One or more aspects pertain to a system to accomplish automated in-situ placement of a concrete wall or embankment, where a fluid concrete is pumped into place, consolidated, and screeded to a finished surface, with remotely controlled or automated equipment.
