Modular building methods and systems using lightweight modular panels, and specially configured transition panels for transitioning from wall to floor, or from wall to roof. Identically configured standard panels are used for constructing the walls, floor, and roof, with transitions from one structure to the next (e.g., wall to floor, or wall to roof). Each of the variously configured panel types includes channels (e.g., 2 pair of channels) formed through the length of the foam body, where the channels are configured to receive splines (e.g., flanges of an I-beam) therein. In the standard panel, the channels may include pairs of top and bottom channels, with the channels offset towards the respective panel major faces. In the transition panels, the channels may be similarly configured, but positioned differently to make the appropriate transition. The splines are connected to a frame, which acts as a template and transfers loads to a foundation.

This invention involves three masonry units that can aid in materializing masonry construction of better quality. The masonry units include the CMH-4, the CVMH-8 and the SNH-4. The CMH-4 includes cells that permit interior wall cavities that can help include larger piping inside walls as well as horizontal piping for sanitary ventilation without losing the traditional way of installing CMU's or interrupting the typical and usually recommended running bond. The CVMH-8 permits the cutting of the unit in different shapes, of which one can be used as framework. The SNH-4 is a concrete unit that can be used as a planting wall, that aids in openings without windows or doors and that is compatible in dimensions with other CMU's. The three units are compatible with existing masonry units, permitting their mixed use according to design needs.

A grille beam structure construction method for a semiconductor factory is configured to perform construction of grille beams without installation of a separate beam mounting the grille beams and to simplify a joint between the grille beams by using studs for mounting of the grille beams and by integrating grille beam members to each other by bolt-fastening. The method includes installing columns, installing studs between the columns at predetermined intervals longitudinally and transversally, mounting grille beams above the columns and the studs, wherein each of the grille beams includes an rectangular-frame-shaped edge beam and the edge beam has a plurality of fastening holes, and matching the fastening holes between the grille beams and inserting bolts into the fastening holes, thereby integrating the grille beam.

A wooden module may include four cross-sectionally square longitudinal pieces of timber, at least six cross-sectionally square transverse pieces of timber, and at least two cross-sectionally square plugs, which may be connected to one another via a plurality of connection plugs. The four longitudinal pieces of timber may be arranged parallel to and spaced apart from one another such that the four longitudinal pieces of timber span a square. The at least six transverse pieces of timber may be arranged over a length of the four longitudinal pieces of timber and may be arranged between the four longitudinal pieces of timber. The at least two plugs may be arranged vertically parallel to one another and to at least four vertical transverse pieces of timber on at least two horizontal transverse pieces of timber and may project from a lateral face of the wooden module.

A deck system is disclosed having a mounting plate with a planar support surface and at least one locating rod extending from the support surface. The locating rod extends in a direction that is substantially perpendicular to the support surface. A beam having a first end and a second end is positioned on the support surface of the mounting plate. The first and second ends of the beam have a slot and the slot is disposed for receiving the locating rod. At least one tread is disposed to extend between the two spaced apart parallel oriented beams. The tread has opposed shoulders on the side of the tread that engages the spaced apart beams. The opposed shoulders are disposed for engaging a side of the spaced apart beams that are in adjacent relationship.
