Some embodiments of the present disclosure provide a roof component of a railway vehicle, and a railway vehicle. The roof component of a railway vehicle includes: two upper boundary beams, the two upper boundary beams being provided at an interval; a camber beam component, the camber beam component being provided between the two upper boundary beams; and a transitional structure, provided on the camber beam component, the transitional structure being connected with at least one of the two upper boundary beams. The technical solution of the present disclosure solves the problem in the conventional art of inconvenient connection between a camber beam component and an upper boundary beam, and a transitional structure of the present application facilitates processing and forming.

A pre-fabricated, portable building comprises a structural support framework formed from interconnected beams defining an interior space therebetween. A floor panel on which the structural support framework is securely positioned. Connection assembly units are mounted to one or more sections of the structural support framework. A removable roof assembly is connected to each one of the connection assembly units on the structural support framework. The removable roof assembly is engineered to be installed or removed while maintaining a maximum height of the interior space without altering dimensions of the structural support framework.

The invention relates to a modular building (2), to be assembled in various sizes and in various environments, having a generally triangular transverse sectional profile, wherein the modular building comprises a double sloping roof (6) over the generally triangular transverse sectional profile, and wherein the one or more double sloping roof panels comprise composite panel material.

This technology comprises a combined accessory of an in-situ concrete 3-D printed horizontal load-bearing member and a preparation method. The combined accessory includes 3-D printed concrete and a bottom mesh, the 3-D printed concrete contains fine aggregates having the particle size of 0.08 mm-4.75 mm, and the fluidity of the 3-D printed concrete is larger than or equal to 110 mm and smaller than or equal to 190 mm; the bottom mesh is a reinforcing mesh or expanded metal, the diameter of the reinforcing bar is larger than or equal to 0.5 mm, and the mesh aperture of the reinforcing mesh is smaller than or equal to 7.5 times of an upper limit of the particle size of the fine aggregate and is larger than or equal to 7.5 times of a lower limit of the particle size of the fine aggregate.

A saferoom/tornado shelter is made primarily of wood and includes walls that can withstand missile impact testing as recommended under Federal guidance and regulations. The saferooms of the present invention can be designed for a single family or small business, or can be designed as a larger community shelter. The wood wall can accommodate various architectural finish treatments and enhancements much more easily than a concrete or steel building saferoom. The walls can be made from dimensional lumber, stacked along its width and the saferooms can be assembled without the need for glue, wood screws or the like.

A modular building unit for use in constructing a building. The building unit has a planar body having two major side faces and two ends between each side face, and a connection interface provided at each of the ends, for connecting similar building units with complemental connection interfaces. The body includes three walls arranged side-to-side and transversely spaced from each other, the three walls thus defining two planar spaces therebetween, and a plurality of reinforcing webs in the first space, for providing structural support to the building unit. The second space defines at least one hollow cavity for receiving a matched insulation insert thereby to impart insulating properties to the building unit.

A module for use in constructing a building includes a ceiling assembly. Wall assemblies are configured for attachment to opposite sides of the ceiling assembly generally at tops of the wall assemblies. A floor assembly is configured for attachment generally to bottoms of the wall assemblies. Connector plates are attached to the wall assemblies. The connector plates are configured to receive fasteners for attaching the ceiling assembly and floor assembly to the wall assemblies. A method of construction using the modules is also disclosed.

A method of constructing a building is disclosed, including selecting a standard dimension less than a wide-load trucking permit limit and designing a building on a grid defined by the selected standard dimension. The building includes a plurality of prefabricated elements, wherein each prefabricated element has a width correspond to the selected standard dimension. The plurality of prefabricated elements includes a wall panel, a roof panel, a laterally resistive frame, and a rebar cage. The method includes fabricating each of the plurality of prefabricated elements at a manufacturing plant and transporting the elements by truck to a building site. The method includes constructing intersecting grade beam footings at the building site and pouring a slab between the intersecting grade beam footings. The grade beam footings include the rebar cage and have a uniform width and depth, the grade beam footings and the slab having contiguous upper surfaces.

A roof for a building comprises a ridge beam for defining an upper edge of the roof, and a first eaves beam for defining a lower edge of the roof. The roof further comprises a first panel connectable to both the ridge beam and the eaves beam, being capable of spanning the distance therebetween and extending over at least a first portion of the area of the roof. In addition, the roof comprises one or more retention structures positionable relative to the first panel and one of said beams and configured to clamp said panel against the other of said beams.

A panelized complex polyhedron structure can be constructed quickly and inexpensively from a plurality panels. According to one embodiment, the structure includes a plurality of panels, wherein a first panel comprises an integrated connecting feature formed unitarily with the first panel and including a faceted feature connected to a plain end of a second panel. According to another embodiment, the first panel includes integrated connecting features including a plurality of planar faceted features, wherein one of the faceted features is connected to a plain end of the second panel. The plurality of planar faceted features are oriented at angles selected to enable a plurality of panel connections necessary to construct the structure. In one embodiment, the panel comprising the integrated connecting features is formed unitarily.
