The present invention is a modular structural building method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

An enclosure including an upper frame, a lower frame, and a lift mechanism operably coupling the upper frame and the lower frame together. The lift mechanism includes first drive shafts and a second drive shaft operably coupling the first drive shafts for operation in unison, and an input operably coupled to at least one of the first drive shafts or the second drive shaft. The lift mechanism transitions the enclosure between a stowed state and a deployed state during a movement of the actuator.

A wall configured to couple to a shelter and extend around at least a portion of a perimeter of the shelter. The wall includes a first end having a first attachment mechanism configured to engage with a second attachment mechanism of the shelter, a second end opposite the first end, a sidewall extending between the first end and the second end, and a third attachment mechanism coupled proximal to the second end and configured to engage with a fourth attachment mechanism disposed on the shelter to couple the wall to the shelter.

The present invention relates to a design structure of an apartment house in which a plurality of apartment units, each of which is a maisonette in which two floors including an upper floor and a lower floor are combined into a single apartment unit, are repeatedly arranged in vertical and horizontal directions, wherein, in the design structure, each apartment unit has a living room disposed on the upper floor and a plurality of bedrooms disposed on the lower floor, double pillars spaced apart from each other are installed on side boundaries of adjacent apartment units, the double pillars include a pair of first pillars disposed inside an apartment unit and a pair of second pillars disposed outside the apartment unit and disposed inside another apartment unit adjacent thereto, a first beam member, which serves as a structure carrying a load, is connected to and installed at the first pillar, a second beam member, which serves as a structure carrying a load, is connected to and installed at the second pillar, and a double pillar connecting beam configured to connect the first pillar and the second pillar is additionally provided on a side surface of a slab of the lower floor.

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 thermal insulating and sealant element can thermally insulate and seal a safing slot within a building construction having a wall construction. The insulating and sealant element includes an elastic sealing element; a formwork; an insulator, which comprises a thermally resistant and/or air tight material; and a supplemental attachment apparatus for attaching the elastic sealing element to an interior wall surface of an interior panel.

A system including a frame and a pair wheel of assemblies to engage with one or more tracks of a structure. The pair of wheel assemblies include a first hub assembly, having a first wheel and a first attachment mechanism to engage with the one or more tracks of the structure, and a second hub assembly having a second wheel and a second attachment mechanism to engage with the one or more tracks of the structure. The system further includes an elongated rod coupling the first hub assembly to the second hub assembly, where a movement of the elongated rod causes the first attachment mechanism and the second attachment mechanism to engage with the one or more tracks of the structure.

A structural member section is provided that may be comprised of horizontal top and bottom flange elements interconnected by one or more vertical web member. The top flange of the member is serrated such that a series of serrations protrude horizontally in at least one direction from a top of the one or more vertical web member or are cut-out from the flange of a rolled shape. In one embodiment, the serrated top flange and at least a portion of the web member are intended to be encased by a horizontal concrete slab or slab-on-deck assembly. The slab material is capable of encasing all exposed surfaces of and curing around each serration to transfer horizontal shear forces between the serrated top flange and the slab material such that the member and slab behave compositely without needing additional reinforcing located within the voids between serrations.
