A bracket system, for suspending pergola beams from an existing structure, the existing structure having a vertical wall and roof rafters that each have a rafter top and a rafter end that extends beyond the vertical wall over a ground surface, each of the pergola beams having a supported end, including a plurality of brackets. Each bracket having a mounting assembly for attaching to one of the rafters, a support assembly for attaching the support end of one of the pergola beams, and a connecting assembly that suspends the support assembly from the mounting assembly. The pergola beams extend over the ground surface, away from the existing structure, supported only by the bracket at the support end and without any vertical supports.

A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.

A monolithic corner encapsulates one or more panels while maintaining structural integrity and maintain hygienic properties. The corner may securely receive one or more panels and provide flexibility to easily adjust the one or more panels. The corner may simplify installation and an ability to adjust connected panels without compromising safety, installation time, and sterility.

The present invention discloses a flexible connecting structure of a prefabricated component and a building main body. The flexible connecting structure comprises multiple layers of cast-in-situ building main bodies spaced up and down, a prefabricated component is connected between two adjacent cast-in-situ building main bodies, a tenon is provided at the lower end of the prefabricated component, a mortise matching the tenon is provided on the top surface of the cast-in-situ building main body, and the prefabricated component is socketed to the lower layer of cast-in-situ building main body by tenon-and-mortise cooperation; and a first flexible layer for reducing the connection rigidity between the prefabricated component and the upper layer of cast-in-situ building main body is provided at the junction between the prefabricated component and the upper layer of cast-in-situ building main body. The present invention realizes a flexible connection between a prefabricated component and a building main body, and avoids the influence of the prefabricated component on the rigidity of the building main body.

In some embodiments, a building block includes alignment elements that interlink with a similar block with a positional offset. For example, the positional offset may be linear and/or rotational. For example, the second cinder block may be rotated with respect to the first block on which it is supports. Optionally, protrusions from the top of the block are positioned to interlink to the vertical slots at a fixed offset between the blocks. Optionally, the protrusions are formed by channels on a mold and/or a mold head. In some embodiments, a structure may be built stacked blocks. Optionally, a decorative face is configured to form a continuous decorated surface across offset blocks. In some embodiments a building block includes a calibration feature. For example, the block may include a ridge on the top of the block that may be shaved and/or ground to adjust the height of the block.

The invention herein disclosed and claimed is an L-bracket and flashing assembly used to mount a rack for supporting a solar-panel array. It uses fewer sub-assemblies and is simpler and faster to install than prior art L-bracket and flashing assemblies.
