An apparatus for an entryway includes: a sheet of material having a top, a bottom, a left side, and a right side, and a sleeve at the top of the sheet of material. The sheet of material has an opening extending to the bottom of the sheet of material between the left side and the right side of the sheet of material from a position below the sleeve. The opening has a left seam and a right seam, wherein a first magnet is positioned at the left seam of the opening and a second magnet is positioned at the right seam of the opening, wherein the first and second magnets are magnetically coupled. A variable-length cross member has a first end and a second end. The cross member is positioned in the sleeve and includes a first securing mechanism at the first end and a second securing mechanism at the second end that secure the cross member respectively to body portions of a first vertical pole and a second vertical pole.

Rigid foam-core construction underlayment is formed to have one broad side covered by a flexible substrate that carries a series of spaced-apart, discrete regions (such as islands or spaced lanes) of resin, each resin region carrying a respective field of male touch fastener elements extending away from the substrate and exposed for engagement, such as by fibers on an inner surface of exterior construction material, such as a roofing membrane.

A tarpaulin apparatus and method for covering comprising a surface sheet having a plurality of sectioned pockets positioned at the corners of the tarpaulin apparatus. Each of the pockets are sized and adapted to accommodate weights that weigh down the tarpaulin and maintain its position when utilized to cover an object or pile. Each of the pockets have an interior and an opening that is secured by a set of hook and loop fasteners to help keep the weights within the sectioned pocket when the tarpaulin is in use. Also positioned at the edges of the surface sheet are a plurality of grommets through which the tarpaulin apparatus may be further secured with rope, twine, wire or other conventional form of line.

Interactive drop cloths are disclosed herein. An example interactive drop cloth includes a safety drop cloth, one or more audio output devices integrated into one or more corners of the safety drop cloth, and a controller that causes an audible alert message to be output by the one or more audio output devices.

A weighted tarpaulin device for covering an article without moving due to wind or other environmental forces includes a tarpaulin with a plurality of pockets dispersed across a face of the tarpaulin. Each pocket is configured for holding a sandbag of a plurality of sandbags. The plurality of sandbags weigh the tarpaulin down when contained in the plurality of pockets.

A device for raising a temporary wall to enclose an area includes a main body, a drive wheel attached centrally to the main body, a motor mounted on the main body and configured to drive the drive wheel, and a hook portion attached each end of the main body. Each hook portion has an arm member extending from the main body, a wheel support member extending from the arm member, the wheel support member extending substantially parallel to the main body, a wheel attached to the wheel support member on a surface facing the main body, and a depth adjustment mechanism configured to adjust a depth of the device by adjusting a length of the arm member. The device also includes a width adjustment mechanism configured to adjust a width of a gap between the wheel support members and a loop member attached to the main body.

A system and method for temporary protection of a damaged roof is provided. The method includes draping a strip of an impermeable membrane over the roof, wherein the end of the strip overhangs the eaves of the roof, placing a rigid, elongated piece of construction material under the end of the strip that overhangs the eaves of the roof, such that the construction material is placed below the eaves of the roof, cutting the end of the strip such that it is coextensive with a length of the construction material and cutting the end of the strip below the construction material, fastening the construction material to the end of the strip, rolling the construction material at least one full turn in the end of the strip, attaching the construction material to the eaves of the roof, and repeating the steps above until the roof is covered in the impermeable membrane.

An acoustic curtain comprising a panel of sound absorbent material within an envelope formed from polymeric sheets, with means for attaching adjacent panels to one another, and wherein the curtain comprises a magnetic element.

A corner-fitting drop cloth adapted to extend along interior and, alternatively, exterior wall corners as needed. The drop cloth may include two sections joined together to extend parallel to both intersecting wall portions with minimal folding or bunching. In some embodiments, the drop cloth comprises a 45-degree seam between the two sections that permits easy unfolding and folding. A distal side of one or both sections may include indicia to assist a user in identifying the drop cloth when folded.

A method of manufacturing a tower structure includes printing and depositing, via a printhead assembly of an additive printing system, one or more printed layers of a wall of the tower structure. The method also includes unwinding at least one continuous roll of a reinforcement material to form at least one continuous reinforcement ring member layer, the reinforcement material comprising a pultruded polymer material. Further, the method includes placing the at least one continuous reinforcement ring member layer atop the one or more printed layers of the wall of the tower structure. Moreover, the method includes printing and depositing, via the printhead assembly of the additive printing system, one or more additional printed layers of the wall of the tower structure atop the at least one continuous reinforcement ring member layer.
