Disclosed herein are embodiments of a duct support assembly. The duct support assembly can include a frame structure and a duct support. The duct support can be configured to be installed in a floor assembly between a first beam portion of a first wall frame and a second beam portion of a second wall frame and to provide a duct exit from the frame structure. The duct support can be configured to transfer a tension and/or compression load. Also disclosed herein are embodiments of a method of using a duct support to provide a duct exit from a frame structure. The method can include positioning the duct support in a floor assembly between a first beam portion of a first wall frame and a second beam portion of a second wall frame.

A basement system includes a concrete basement and a drain channel. The concrete basement includes a basement slab and a basement wall. The basement slab presents a floor surface, with the basement wall extending about the floor surface. The basement slab and basement wall cooperatively define a trench that extends along the basement wall and below the floor surface to receive water in the basement. The drain channel is located at least partly in the trench to collect water therein. The drain channel includes an elongated channel tube and an upright riser integrally formed with the channel tube. The channel tube includes axially-extending opposite side walls that at least partly define an interior to receive water, with at least one of the side walls presenting openings that permit water ingress from the trench to the interior. The riser extends upwardly from one of the side walls and engages the basement wall.

An under deck drainage system is mounted on rail members connected to the bottom of deck stringers in a transverse orientation thereto. The rail members increase incrementally in thickness from the proximal end of the deck to the distal end of the deck where the water is discharged from the under deck drainage system so as to provide proper slope for the drainage of water by the under deck drainage system. A ventilation panel is mounted to the periphery of the deck to enclose the under deck drainage system yet provide an adequate supply of air to the system for drying water therefrom. The ventilation panel is formed with a ventilation portion that is located below the level of the deck stringers, and with a hem portion that has sufficient length to cover the under deck drainage system from view even at the distal end of the deck.

A deck drainage system includes a bracket, a locking bead, and a sheet. The bracket includes a first leg and an elongate receiver connected to an end portion of the leg. The elongate receiver defines a substantially round cross-sectional profile. The locking bead is an elongate member that defines a slit in an outer surface thereof for receiving the sheet. The locking bead is configured to be received in the receiver.

A drain assembly comprises a shroud, a shank, and a frame. The drain assembly may further comprise a shim with an angled top surface. The frame may have an angled bottom surface. A rotational orientation of the angled top surface of the shim relative to the shank and a rotational orientation of the angled bottom surface of the frame relative to the shank may be independently adjustable, thereby allowing for the top surface of the frame to be both angularly and rotationally adjusted relative to a central axis of the drain assembly independent of the positional height of the shank. The drain assembly may further comprise a cover having bendable tabs. The bendable tabs may be disposed around a periphery of the cover and may be configured to contact an angled inner surface of an upper bowl of the shroud, such that the bendable tabs bend around the frame, thereby locking the cover onto the frame.

A method for retrofitting a building using a lift system and a component kit for performing the method are provided. The shaft of the lift system extends over at least two stories 3 and comprises a self-supporting sheet metal box made of at least one steel plate, which is provided for receiving a cabin of the lift system together with its guides and drive devices. The sheet metal box of the shaft has a profiled cross section, which forms a cross-sectional area in the cross-sectional plane within the sheet metal box, which essentially covers the area required by the cabin and its guides and drive devices, and additionally contains the area of a lift platform for bridging a distance between the cabin and the building. The method provides prefabricating the lift system and installing it to the building.

The invention relates to a composite element (10) for use in construction, in particular building construction or civil engineering, which composite element comprises at least two components and at least one fastening element (11) for connecting the components. A first component has at least one assembly pin (13), which is cylindrical in particular. The fastening element (11) is configured as a clamping element such that it can be force-fittingly connected to the assembly pin (13). The invention further relates to a use of a fastening element (11) configured as a clamping element.
