A double-shelled load-bearing structure module of any geometric shape, is formed from top and bottom secondary shell elements. A double-shelled load-bearing structure in the form of a primary shell structure is joined with the module, made of individual assembled load-bearing structure modules of this kind having statically necessary filling rods. The secondary shell elements have, in each corner, a connection pocket, which is open at the top or bottom or is open at the top and bottom, of appropriate size for connecting a plurality of load-bearing structure modules. The connection pocket, at least on the outside, on the outer vertical surfaces of the secondary shell elements, is delimited by preferably metal profiles or metal sheet. Connection tabs can also be disposed in each corner instead of connection pockets. The connection tabs are formed from angular surfaces, preferably metal sheet, protruding towards the intermediate space between the secondary shell elements.

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.

The present invention concerns a construction system for a building module, whose main elements are made of plastic material, providing a robust construction in an easy and quick manner. The system includes a set of main beams (1) adapted to be assembled end-to-end to form an open structure in the shape of a 3-dimensional rectangular frame. The system further includes secondary beams (11), adapted to be assembled between parallel and opposite main beams, and flat facade elements (3) insertable against each other between two adjacent parallel beams. Each facade element (3) includes a rectangular flat plate provided with two folded opposite edges (3A) intended to be hooked with adjacent parallel beams. Each main beam has a rectangular cross-section including, on the four sides thereof, a projection (21) parallel to the side and spaced therefrom leaving an opening to receive a folded edge of a flat facade element. Each secondary beam (11) includes, on two opposite faces, at least one projection leaving an opening to receive a folded edge of a flat facade element (3).

A building structure that can be assembled easily with high assembling precision is provided. The building structure of the present invention is a building structure for transmitting a load on a roof to a post, and includes a unit (10) joined to a post (20). The unit includes three or more first beams arranged in parallel in one direction and three or more second beams arranged in parallel in another direction intersecting the one direction. Each first beam and each second beam has a truss structure. In a section where the first beam intersects the second beam, an upper chord of the first beam is disposed on an upper chord of the second beam and is joined to the upper chord of the second beam via a joining member, using a fastener. In the section where the first beam intersects the second beam, a lower chord of the first beam is disposed on a lower chord of the second beam and is joined to the lower chord of the second beam via a joining member, using a fastener.

An edge seal for a modular thermal isolation barrier for preventing passage of air through a gap in a data processing equipment arrangement includes a seal portion and a base portion. The seal portion is formed of a resilient material capable of deflection by a rigid adjacent structure. The base portion is formed of a rigid material and includes a pair of side channels opening at opposite sides thereof and a panel-receiving end channel. Each of the pair of side channels includes a first distal flange arranged to extend inwardly from one side of the respective channel and a second distal flange arranged to extend inwardly, and toward the first distal flange, from the other side of the respective channel, whereby each side channel is generally C-shaped and includes a channel opening having a width that is narrower than a width of a channel interior. Each of the seal portion and the base portion has a generally uniform cross-sectional shape.

An atrium hybrid greenhouse. The greenhouse employs the skeleton structure of columns, girders, and joists of an industrial metal building on which are spaced external and internal walls, and spaced roof and ceiling. The spaced walls form a wall cavity therebetween, and the roof and ceiling form a ceiling cavity therebetween. A radius cave channel is used to connect the wall cavity and the ceiling cavity for fluid flow therebetween. The external and internal wall and roof/ceiling panels are formed of relatively stiff light transmissive material such as polycarbonate. The formed cavity also provides insulation value.

A modular support frame comprises trusses, purlins transverse to the trusses, and vertical posts supporting the various trusses. A supply of wedges permits flange-type connectors to be joined to complementary connectors throughout the foundation. The trusses are arranged end-to-end in parallel rows, each row comprising at least one pair of trusses or more depending on the desired size of the foundation. Vertical posts are positioned between the ends of each of the trusses within a row and at opposing ends of the row, and each post comprises a pair of flange-type connectors at predetermined heights. Each of the trusses is terminated at either end with a pair of complementary connectors such that adjacent in-line trusses can be mounted to the post between them and the outer pair of trusses can be mounted to the posts terminated the row. Purlins extend perpendicularly between the trusses in adjacent rows to reinforce the frame. To that end, the trusses comprise flange-type connectors and the purlins are terminated at either end with complementary connectors.

A method and apparatus according to which a blast resistant shelter is assembled. The blast resistant shelter includes first and second structural members, a third structural member coupled to the first and second structural members, a first airway adjacent the third structural member, and a first blast panel pivotably mounted to the third structural member and adapted to pivot thereabout in response to a blast wave. In a first configuration, the first blast panel is detachably connected to a first portion of the blast resistant shelter and prevented from pivoting about the third structural member so that the first blast panel obstructs air flow through the first airway. In a second configuration, in response to the blast wave, the first blast panel is detached from the first portion of the blast resistant shelter and permitted to pivot about the third structural member to permit air flow through the first airway.

A modular framework having a plurality of elongate structural members interconnected by brackets is provided. Each of the brackets includes at least one tubular socket to receive a structural member, and an array of holes is provided on a face of the socket to permit connection of an attachment to the bracket to support ancillary components.
