A modular thatch panel for a thatch roof is provided that distinguishes a perforated louvered drainage and drying tray and an insert thatch bale. The tray has louvers at the bottom aspect of the tray and perforations distributed over the tray bottom. The bottom surface of the tray faces a barrier (e.g. water, thermal and/or fire) which overlays a roof panel. The tray and the barrier are at a distance suitable for airflow in between the two layers. The insert thatch bale is compacted, bonded and inserted in the perforated louvered drainage and drying tray.

A floor drain and method of manufacture is described. The drain assembly includes a transverse bar in the throat of the drain base. The bar supports a substantially vertical, elongated connecting member or fastener to the strainer flush with the floor, and acts to transfer any vertical downward forces to the side wall of the drain base. The drain assembly may be milled from a single piece of metal and include an integral no hub for greater structural integrity.

The sealing device for construction comprises a duct and a linking member mounted around and rigidly connected to the duct, wherein the duct comprises: an axial main portion around which the linking member is mounted, a radial bead formed on the main portion and extending radially outwards, and a distal end portion extending the main portion radially outwards and which is axially facing the bead to form therebetween an outwardly radially open annular mounting slot, the distal end portion extending radially beyond the bead, the main portion, the distal end portion and the bead of the duct being made of one piece, the linking member being mounted in the mounting slot and gripped axially between the bead and the distal end portion of the duct.

The present disclosure provides sealing devices and construction methods thereof. The sealing devices include a duct having a main axial portion, an intermediate annular portion facing the main axial portion, and an annular end portion facing the intermediate annular portion. The intermediate annular portion and the end annular portion are connected by an annular fold so as to form an axial annular mounting slot that is axially open opposite this annular fold. A connecting member comprises a radial plateau and, around a through-opening, an axial annular mounting portion. The axial annular mounting portion of the connection member is engaged and grasped in the axial mounting slot between the intermediate annular portion and the end annular portion of the duct.

Disclosed is a system and method of constructing modular homes, which are assembled from a numbered of prefabricated components and delivered as finished goods using standard containers. The modular design further provides for a self-sufficient structure where the three main engineering systems, namely, plumbing, electrical and HVAC, are completely integrated allowing the structure to maximize energy usage efficiencies. Emphasis is placed on using only environmentally friendly materials and on recycle or multi-purposing components into energy or resource gathering and production. Another emphasis is placed on speed of assembly using standardized structures that streamline on the job assembly processes.

A rainwater distribution system for storing and distributing rainwater includes a first container configured to store rainwater and having a bottom wall and a side wall; a planting container being elevated off of the bottom wall and within the first container, and having a planting container bottom wall and a side wall; a planting container support configured to elevate the planting container off of the bottom wall and within the first container; a cascade aperture having a cascade filter, the cascade aperture positioned on the side wall of the planting container, and allows the rainwater that enters the planting container to exit the planting container into the first container; and an outlet aperture positioned on the side wall of the first container and configured to allow the rainwater to exit the first container at a controlled rate.

A cover for water flow inlet for rainwater drainage of roof and buildings is disclosed. The inlet cover comprises an outer formation forming a plurality of ridged fins to avoid the vortex formation of rainwater entrainment and to protect the cover from debris materials and a central plate member. The central plate member has a profiled lower surface. The plate member is of an inverted shape with a plurality of ridged formation or channels on the lower surface to further eliminate formation of air inducing and vortices, therefore promoting high volume laminar flow of water in the inlet pipe of the drainage system.

A two-stage filtering drain cover that can be retrofitted to an existing, original construction, areaway drain cover. The filtering drain cover of the invention inhibits the accumulation of debris on the existing drain cover, and passage of debris into the drain, and helps to prevent clogs and flooding. The outer cover member of the device is configured with passages that permit liquid flow through the outer cover while filtering larger size debris particles that may be entrained in the passing liquid. A perimeter wall on the outer cover and with similar liquid flow passages stops larger debris from passing the outer cover. An inner filter member fits within the outer cover and is configured with relatively smaller passages to obstruct smaller sized debris that may have penetrated the outer cover from passing into the drain.

A floor drain and method of manufacture is described. The drain assembly includes a transverse bar in the throat of the drain base. The bar supports a substantially vertical, elongated connecting member or fastener to the strainer flush with the floor, and acts to transfer any vertical downward forces to the side wall of the drain base. The drain assembly may be milled from a single piece of metal and include an integral no hub for greater structural integrity.

The present invention is a roof drain assembly that comprises a dome mounted to a drain body by shock arrestors and a roof clamp that is securable to the drain body. A screen is positioned around the inlet and between the drain body and the dome. The shock arrestors and screen permit the dome to compress against the drain body while simultaneously absorbing the energy from an impact. As the shock arrestors compress, the screen also compresses. The resiliency of the screen and the shock arrestors permit the dome assembly to return to its passive state once the compression force is removed.
