System for modular building construction

InactiveUS20080134589A1Facilitating selective interconnectionConstruction materialLighting and heating apparatusEnvironmental systemsModular unit
Construction systems for erecting building structures comprise a plurality of prefabricated interconnectable modular building units, each unit not meeting at least one of the ISO certification criteria for transport of cargo but each unit comprising a frame shaped as a rectangular parallelopiped and comprised of framing members and a plurality of nodes, each node situated at a corner of said frame for selective interconnection with other units, the nodes and the exterior dimensions of the frame conforming to ISO shipping standards such that each unit is transportable using the ISO intermodal transportation system, and such that when the units are aggregated horizontally and vertically and adjacent units are interconnected, a building structure comprising at least one habitable space is formed. The modular units are assembled in a factory remote from the job site, and are there constructed to a semi-finished state, including installation of one or more of interior fit-out systems and finishes, exterior envelope systems, plumbing systems, electrical systems, environmental systems, and fire protection systems, following which the semi-finished modular units are transported from the factory to the job site, where they are craned into place and secured to form the structure being erected, a plurality of adjacent pairs of semi-finished modular units also being “stitched” together, and the semi-finished modular units are thereafter constructed to a finished state.

Buckling control support with diamond type energy dissipation units at ends

The invention discloses a buckling control support with diamond type energy dissipation units at the ends. The buckling control support is characterized by being composed of end restraint sections, energy dissipation sections and a straight supporting section, wherein the two ends of the buckling control support are connected with beam and column members or joints into a whole through high-strength bolts to achieve the purpose of improving the lateral stiffness of the members. The buckling control support with the diamond type energy dissipation units at the ends maintains resilience under the action of a small earthquake and enters a yield stage under the action of a medium earthquake or a major earthquake, and the effect of a damper can be achieved due to the good hystersis energy dissipation performance of the buckling control support. Compared with a traditional buckling control support, the procedures of adding a sleeve outside a core energy dissipation member, performing grouting and the like in the traditional manufacturing process are omitted in the manufacturing technology, and manufacturing is convenient; the support can be prefabricated in a factory, the member quality is guaranteed, the workload of site construction operation is reduced, and energy conservation and environment protection are achieved.

Fire retardant panel door and door frame having intumescent materials therein

A fire retardant panel door and door frame that prevents the spread of fire through the door during a fire. The fire retardant panel door has at least one door panel and stiles and rails. The door panel includes an interior center composite section formed by a first plurality of layers of intumescent materials and a first plurality of layers of fire resistant materials disposed between and laminated to a pair of outer sections formed of wood for enclosing the interior center composite section to form a composite laminated door panel. Each of the stiles includes a first center core formed of wood enclosed by a second plurality of layers of intumescent materials and a second plurality of layers of fire resistant materials; and the second layers of intumescent and fire resistant materials are enclosed by a first applique layer formed of wood to form a composite laminated stile. Each of the rails includes a second center core formed of wood enclosed by a third plurality of layers of intumescent materials and a third plurality of layers of fire resistant materials; and the third layers of intumescent and fire resistant materials are enclosed by a second applique layer formed of wood to form a composite laminated rail. The first, second, and third plurality of layers of intumescent materials are activated to expand upon exposure to heat and/or fire to prevent the heat and/or fire from passing through at least one door panel, the stiles and the rails of the panel door during a fire for at least 90 minutes. At least one door panel is connected to the panel door by tongue and groove joints; and the tongue and groove joints have a fourth plurality of layers of intumescent materials and a fourth plurality of layers of fire resistant materials in the tongue and groove joints; and wherein the fourth plurality of layers of fire resistant materials in the tongue and groove joints are activated to expand upon exposure to heat and/or fire to seal the joints in order to prevent the heat and/or fire from passing through the panel door during a fire for at least 90 minutes.
