摘要:
A dome-shaped roof structure for a large construction such as an athletic stadium is capable of partly opening according to the environmental conditions such as weather conditions. The dome-shaped roof structure includes a stationary roof section having a central opening and fixedly secured along an outer periphery thereof to the side wall of the large construction, and a movable roof section including a plurality of roof units corresponding to a plurality of divisions of the central opening and each capable of being radially moved between an open position where the roof unit is supported on the stationary roof section and a closed position where the roof unit is supported on a beam in the central opening.

A structural unit for forming a building, which structural unit comprises at least three elongate members which are connected to each other to define an area, a covering of a flexible material which is secured to the elongate members and which covers the area defined by the elongate members, and a locking device which connects at least one pair of the elongate members, the locking device being such that it operates with a wedging action whereby tightening of the locking device causes the two elongate members to move with respect to the locking device such that the two elongate members move apart to increase the surface area of the structural unit and thereby tighten the covering of the flexible material.

What is disclosed is a rigid, one-piece, shaped body, made of a biaxially stretched synthetic resin in the form of a sheet at least 1 mm thick, the edge of which does not lie in a single plane, and the surface of which is smaller than a flat initial surface enclosed by the edge and preferably approximates the mathematically minimum surface enclosed by the edge, is suitable according to the invention as a lightweight building element having high resistance to buckling. The new shaped bodies are made by shaping a flat sheet of biaxially stretched synthetic resin at least 1 mm thick, while in the thermoelastic state, so that the edge of the sheet is brought into a configuration which does not lie in one plane, and the surface enclosed by the edge is allowed to shrink back partially while in the thermoelastic state, whereby a shrinkage of the edge of the sheet is prevented by clamping the edge, and the resulting shaped body is cooled below the softening temperature before the edge clamping is loosened.

A space enclosing structure, the underlying shape of which is a portion of a polyhedron comprised of a regular arrangement of regular pentagons, equilateral triangles, rhombi, right angled parallelograms and rhomboids. The structure permits the use of square and/or rectangular standardized prefabricated square or rectangular building units such as doors, windows, solar panels, etc., without any alteration of the basic shape of the structure, as such prefabricated units may be used to replace any of the square or rectangular faces of the polyhedron. Each face other than a right angled parallelogram is abutted on each side by a right angled parallelogram. Each right angled parallelogram is abutted on two opposite sides by rhomboids and/or rhombi and on the other two sides by a pentagon and a triangle.
摘要:
A structural framing system and apparatus for use in the fabrication of a structural framework of selected geometric configuration of cast material, for example, concrete or plastic. The method and apparatus of the present invention includes a generally hollow hub form defined by a generally continuous shell of selected geometric form to provide a locus for radiating and outwardly extending frame member forms, which communicate with the hub form where a suitable hardenable material is provided to fill the hub form and the frame member forms to provide a self-supporting structural framework of interconnected hubs and frame members, the frame members extending divergently outwardly from the hub members. Structural reinforcements such as reinforcing steel can be attached within the hub to extend divergently outwardly through the frame form members.
摘要:
A composite structural material is disclosed which comprises a profiled steel sheet and an insulating layer bonded to the profiled steel sheet on at least one side thereof, said insulating layer comprising an expanded mineral core layer bonded with an inorganic binder or a mixture of inorganic binder and a small amount of organic binder. The steel sheet has joining means extending therefrom and into the insulating layer. The composite structural material may be used as a roof material.
摘要:
An under-roof drainage device for draining moisture condensation on the undersurface of a roof or ceiling. The device comprises a plurality of elongated unit panels each having a longitudinal central portion dividing the unit panel into a pair of panel sections with opposite free edges, the panel sections each being sloped downwardly from the central portion toward the free edge. A male half member extends downwardly from the free edge of the panel section. There are also provided a plurality of gutter means each having the same length as the unit panel and including a female member formed centrally on and extending along the gutter means. The adjacent unit panels provide mated male half members detachably interfitting with the female member on the gutter means. The assembled device is mounted beneath a roof, or used as a ceiling with the gutter means inclined relative to the horizontal for the drainage.
摘要:
In a building construction method a plurality of building segments are coupled together and raised in unison from a central control point via a crane. The crane has a plurality of lifting cables selectively driven from a plurality of winches under the control of the operator. The building segments are pivotably coupled together for lifting into position and for locking together to form a rigid self supporting building structure. Successive layers of the building are hoisted into position via detachable pulleys affixed to the previously raised building segments.

A plurality of laminated ribs are anchored to a circular base and extend upwardly and inwardly to a top cone to which they are secured. Strips of insulating board are secured transversely around the ribs in overlapping relationship and a sealing strip covers the junction between adjacent ends of the board. The building can be insulated internally and finished conventionally if desired.
