A perimeter frame used in a construction of floors or roofs of buildings, including three superior radial sub-frames, three inferior radial sub-frames, and six non-perpendicularly interconnecting top hat sub-frames, wherein each superior radial sub-frame is located between a pair of inferior radial sub-frames such that there is a 60° angle between the first and second longitudinal axes of any two adjacent radial sub-frames, and wherein the innermost blunt end portions of the superior radial sub-frames are interconnected to define a primary hexagon structure at a centre of the perimeter frame, and the innermost blunt end portions of the inferior radial sub-frames are connected to a converging region of adjoining surfaces of each adjacent pair of superior radial sub-frames to define a secondary hexagon structure around the primary hexagon structure, and wherein the overhang end portions and the outermost blunt end portions define six corners of a hexagonal perimeter frame.

A large-angle sloping roof steel structure connected to a main body structure, including: an intermediate platform, inclined main supporting steel columns circumferentially connected at four corners of the intermediate platform, constructing steel columns and wind-proof surrounding beam connected between top ends of the inclined main supporting steel columns, where roof purlin are connected between the adjacent inclined main supporting steel columns at intervals. The invention provides a top-down inverted construction method for a large-angle sloping roof with a steel structure as the main structural form. By using the method, the operation safety of an inclined main stressed vertical member during the installation process can be ensured, and the investment of supporting measures is reduced by preferentially installing the intermediate platform, thus effectively ensuring the installation progress, quality and safety of the sloping roof steel structure. The present invention can be widely applied to sloping roof construction.

Disclosed is a waterproof roof for an outdoor shed and the outdoor shed, the waterproof roof including a roof frame and a roof plate group matching with the roof frame for installation, wherein the roof plate group includes a plurality of roof plates spliced in sequence, each of the roof plates includes a plate body and a waterproof layer covering the plate body, the waterproof layer at least covers an upper surface of the corresponding plate body, and the waterproof layer is fixedly installed on the corresponding plate body by means of a binder.

A skeletal structure and method of assembly are provided. The skeletal structure includes one or more vertical columns, one or more upper tracks operatively attachable to the vertical columns, and one or more base tracks operatively attachable to the vertical columns. Upper brackets are attached to the upper tracks, such that the upper brackets attach the upper tracks to the vertical columns. Base brackets are attached to the base tracks, such that the base brackets attach the base tracks to the vertical columns. The skeletal structure is freestanding upon attachment of the upper tracks and the base tracks to the vertical columns.

This present application relates to a novel roof supporting system for use with outbuildings, such as gazebos, rotundas, and the like. The roof supporting system of the present invention eliminates the need for unsightly and architecturally limiting internal roof joists to account for the horizontal component of the live and dead roof loads transferred by the roofing rafters, and also eliminates the need for rafter tails to extend over the perimeter joist or wall members to create a roof with a clean edge appearance.

A dwelling assembly that has a continuous sidewall and an opening for a door and a window. A roof assembly is provided with first and second roofs that are spaced apart such that the outer roof acts as a heat shield for the inner roof to ensure the interior of the dwelling is a minimum temperature. In addition, ballast boxes are utilized in order to provide additional weight to the dwelling and a planting area in association with the dwelling assembly.
