An installation tool and method for spherical latticed shell structure is provided. The spherical latticed shell structure includes a plurality of latticed shell units. The installation tool includes a support frame, a hoisting system, a fixing frame and stay rope assemblies. The support frame is arranged on one side of a to-be-installed spherical latticed shell structure. The fixing frame is connected with the hoisting system. The hoisting system is arranged on the support frame for hoisting the fixing frame. The stay rope assemblies are connected with the fixing frame and the latticed shell units.

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.

The present invention discloses an integrated steel concrete building and its construction method. The building comprises a plurality of prefabricated room modules of steel, each including at least one column having a structure of hollow steel tube, which has an inner chamber inserted with penetrating rebars and poured with concrete. The penetrating rebars extend upwardly out of the column of the prefabricated room module into an inner chamber of a column of a prefabricated room module of an upper floor.

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 building block comprises a rigid housing defining a chamber and plant fibers contained within the chamber. A construction system comprises a plurality of such building blocks, selectively stackable to form a wall. A method of construction comprises obtaining a plurality of such building blocks, inserting plant fibers into the chamber, and stacking the plurality of building blocks to form one or more walls.

A modular building section defining the roof and opposing walls of a modular clearspan building. The building section includes a roof portion extending in a longitudinal direction between opposite first and second ends, and a pair of first and second legs, each leg pivotally attached about a pivot axis to the roof portion proximate a roof portion end. Each of the first and second legs has a stowed position in which the leg generally extends in the longitudinal direction and is in superposition with the roof portion, and an expanded position in which the leg depends from the roof portion and generally extends perpendicularly to the longitudinal direction. The legs are moveable independently of each other from their respective stowed positions to their respective expanded positions under the influence of gravity during lifting of the roof portion. Also disclosed are methods for constructing a modular clearspan building.

Systems and methods are provided for securing a transport device to preexisting studs or support members. One embodiment includes a clamp assembly with a compression fitting adapted to be secured to a plurality of different sized studs or wall supports, and further to support additional supports including, but not limited, horizontal support members. A transport device is further provided that is selectively connectable to clamp and support members of the disclosure. In another embodiment, a hook bracket is provided which includes a projection configured to be positioned in a hole through a stud. The extension may include a notch to engage a portion of the stud. The hook bracket includes at least one aperture adapted to secure the hook bracket to a support member operatively interconnected to the transport device.
