Abstract: Loq·kit is a mass-produced system of interchangeable building components for assembling single or multi-family houses. The building components are of three varieties: structural frame, in-fill, or snap-cladding components. Except for bolted structural frame connections, all connections between parts are snap-lock, and may be released. With snap-lock interfaces and a modular dimensional relationship between components, they can be reconfigured in near endless variety. The components all share a common dimensionality that is derived from a regulating grid. The grid utilizes an alternating sequence of two modules—a module A, and a smaller module B. The A,B,A,B rhythm of gridlines is used to regulate component connection locations in three dimensions. The alternating-sequence grid works by establishing a standard connection width, module B, for making connections between components. Each possible connection width is spaced from another by a common module A.

Abstract: The present invention discloses a grouted tubular energy-dissipation unit comprising an inner tube and an outer tube. The inner tube is coaxially inserted into the outer tube defining a gap within a lapping portion of the tubes for receiving expansive cement grout.

In case of earthquake, the sliding friction between the tubes and the expansive cement grout can absorb energy. The present invention does not require high precise in manufacturing and constructing, saves steel and has low cost. It is only need to replace the grouted tubular energy-dissipation unit when the present invention is damaged in earthquake, which is very convenient.
