Abstract: A modular plural-story building construction system having (a) a series of rectangular modules, each having only two bounding planes for transmitting vertical loads opposite each other and joined by a floor panel and open on top, and (b) a series of rectangular modules, each having only two bounding planes for transmitting vertical loads opposite each other and joined by both a floor panel and a ceiling panel. The (b) modules are used only on the top story, and the (a) modules are used for all lower units. The modules on each level are installed with conjugation of the location of the bearing walls, i.e., so that the bounding planes for transmitting vertical loads of any one module lie perpendicular to the planes of the bounding planes for transmitting vertical loads of all immediately adjacent modules on the same level. The modules on successive levels are arranged so that the bounding planes for transmitting vertical loads above are aligned with those below.

Between two said hammer-shaped elements belonging to two consecutive plane plates which are approached to each other at the moment of the assembly there is interposed a connection element so that said two consecutive plane plates are connected to each other forming an angle which depends on the dimensions and shape of said connection element.

Abstract: An elongated tubular ground anchor having a leading driving end with an internal impact receiving abutment and a tapered out-turned trailing end has an external cable swingably secured thereto about midway between said ends but rearwardly of the center of mass of the anchor, is guided and driven lengthwise into the ground to a desired depth by a ram entering the trailing end and impacting the abutment with the cable extending above ground from the hole in the ground formed by the anchor and driving ram. The cable is pulled or tensioned causing the trailing end of the anchor to plow into the ground forming a fulcrum to rotate or tilt the anchor from its upright driving position to an inclined position transversely of the hole and with the leading end remaining lower than the trailing end. The driving ram may be hollow and a concrete slurry pumped through the ram as it is retracted from the anchor and hole to fill the hole with the cable surrounded by the slurry.

Abstract: An air terminal building consisting of an arrival hall and a departure hall and one waiting hall possibly commonly used by both departing and arriving passengers.

Abstract: Horizontally uneven wooden floor joists are each provided with a horizontal opening extending transversely thereof. A connecting rod member is inserted into such opening so that the ends of the rod protrude to both sides of the joist, the rod itself extending generally horizontally. The connecting rods are then subjected to tension forces generated by adjustable tension means of the type of a rod-and-buckle mechanism anchored to other connecting rod members provided in adjacent joists. The invention thus provides an extremely simply straightening method and apparatus avoiding the common cutting of high or low floor joists at their crest or dip and replacing the cut-out portion by a new joist.

Abstract: A foldable shed or enclosure consisting of a rear wall, a front wall including a door, centrally foldable side walls hinged at their front and rear edges to the side edges of the front and rear walls, a floor hinged to the bottom margin of the rear wall and a roof connected at rear side edge portions thereof to the upper side edge portions of the rear wall by link bars. A foldable strut bar is pivotally and swivelly connected to the top marginal portions of the front sections of the foldable side walls, the strut bar having a locking mechanism which locks its segments in horizontal positions when the side walls are unfolded to their planar positions. By raising the floor against the rear wall, unlocking the strut bar, folding the side walls inwardly and folding the roof downwardly, the shed can be folded to a compact flat condition with the roof and link bars acting to clamp the parts together.
