A multi-part roofing underlayment having independent release liners, where the underlayment comprises separable portions attached adjacent top edges of the separable portions, creating an interface therebetween into which roofing components may be inserted, easing installation and better mitigating wind-driven rain and ice dam related roof failures. Embodiments provide the multi-part roofing underlayment in sheet and roll forms and with various configurations of release liners, adhesive layers, granular layers, selvedge edges, and plastic layers.

According to embodiments described in the specification, a wrap for a steel lintel positioned above a structural opening of a structure includes a plastic sheet member for placement on the steel lintel wherein the plastic sheet member is contoured to cover the steel lintel across a width of the structural opening; and wherein the plastic sheet member extends to cover a lower flange of the steel lintel providing a flashing at an interior angle of the steel lintel.

A heat shrinkable tube-covered rebar basically solves a problem of corrosion of a rebar embedded in a concrete structure by covering the rebar with a heat shrinkable tube, which is a polymer material, and a thermosetting resin to prevent the rebar embedded in the concrete structure from corroding, and easily integrates a reinforcing bar with the heat shrinkable tube and perform a first anti-corrosion treatment on the reinforcing bar by applying a thermosetting resin between the reinforcing bar and the heat shrinkable tube.

A curb assembly is provided for mounting on a sloped, standing seam metallic roof, in order to provide support for a roof fixture, such as an exhaust fan or skylight. The curb assembly includes a box-like structure mounted atop the roof in surrounding relationship to a roof opening. The curb assembly further includes an underlying, below-roof frame assembly. Specialized upper and lower end connection structure serves to securely mount the curb assembly to the metal roof.

A protective cover for concrete anchor bolts includes a hollow, box-shaped housing having a bottom wall with a plurality of elongated, narrow slots thereon that are positioned and spaced to receive various patterns of cast-in anchor bolts. A top wall includes a plurality of wide openings to provide to access to the anchor bolts. Accordingly, a worker superimposes the housing onto a set of concrete anchor bolts with each received within one of the narrow slots on the bottom wall. Using the wider openings on the top wall, the worker tightens nuts onto the anchor bolts to secure the housing to the underlying concrete prior to pouring a surrounding floor. Once the surrounding concrete floor has dried, the nuts are removed and the enclosure is lifted from the formed indention.

A heat-insulating waterproof structure includes a heat-insulating waterproof member arranged on a building body. The building body includes a foundation and an exterior wall body arranged on the foundation. The exterior wall body includes a metal fitting arranged on the foundation, a column set on the foundation with the metal fitting member located in between, and a backing arranged on the column. The heat-insulating waterproof member includes a heat-insulating member and a waterproof member integrated with the heat-insulating member. The heat-insulating waterproof member is located at an outer side of the exterior wall body along the exterior wall body at a height where the metal fitting is located.

A system and method for inhibiting oxidation of a metal lintel in a masonry wall. An anti-corrosion unit is built into the structure of the masonry wall above the lintel. The anti-corrosion unit has a reservoir housing that retains a volume of a protective oil. The reservoir housing releases the protective oil over time through dispensing holes in a first surface of the reservoir housing. The first surface of the reservoir housing is placed into contact with the lintel within the structure of the masonry wall. The protective oil is released onto the lintel along the contact interface. The protective oil coats the lintel, therein inhibiting oxidation of the lintel.
