The present invention relates to a modular assembly, a site factory, for at least partially enclosing a site during construction of a structure. The modular assembly comprising: a plurality of portal frames, each portal frame comprising two columns and a roof beam, each column and roof beam comprising a plurality of pre-assembled units; a jack-up frame for each column; at least two first rails, each of the first rails being mounted to at least one of the roof beams; at least one second rail slidably mounted to the at least two first rails; and a plurality of panels of a flexible material configured to provide a full enclosure of the site and mounted above the roof beam. The or each second rail is configured to slidably receive at least one lifting device. The pre-assembled units are configured o be connected on site, and lifted using said jack-up frames, to form the portal frames, and wherein each first rail, and the or each second rail are configured to be mounted on the portal frames on site.

A system, comprises a first pulley and a first pulley mount constructed and arranged to couple the first pulley to a curtain including a zipper. The first pulley mount comprises a first portion and a second portion that are removably coupled to each other with a portion of the curtain between them when mounted to the curtain. A second pulley in included along with a second pulley mount constructed and arranged to couple the second pulley in position relative to the curtain. An elongated pull is coupled to the first pulley, the second pulley, and a zipper pull of the zipper.

A barrier device includes a horizontal portion formed of a polymer, the horizontal portion having a largest substantially planar surface and a thickness perpendicular to its largest substantially planar surface. The barrier device includes a vertical portion formed of a polymer and coupled with the horizontal portion, the vertical portion forming a substantially ninety-degree angle relative to the horizontal portion, the vertical portion having a largest substantially planar surface and a thickness perpendicular to its largest substantially planar surface. In implementations the thickness of the vertical portion is substantially equal to the thickness of the horizontal portion. A width of the horizontal portion, perpendicular to the vertical portion, is shorter than a height of the vertical portion perpendicular to the horizontal portion—in some cases no more than one third or one fifth its size. In implementations the barrier device may be used to protect an installed baseboard.

A partition assembly kit, includes a receptacle, a first strap, and a first zipper having a length greater than 50% a height of a standard-sized entry way. The strap and the first zipper are provided within the receptacle.

The present protective barrier is similar to those commonly installed beneath ceilings during construction work being performed on ceilings or roofs of buildings, wherein two or more sections are sewn together to construct the protective barrier. However, the present protective barrier also comprises a dustcover, which covers the seam entirely preventing dust from passing through holes created when the seam is sewn using a thread or similar means.

A tent for surrounding a base of an upstanding structure on a support surface is disclosed. The tent features a covering with a top edge arranged to follow a perimeter of the structure base and a bottom edge arranged to define an outer periphery of the covering. The tent additionally features a base strap arranged for forming a closed loop about the structure base at a predetermined height above the support surface. The base strap supports a first attachment member, and a second attachment member is located along the top edge of the covering for cooperating with the first attachment member to fasten the covering at the structure base. A tightening strap along the top edge of the covering but behind the second attachment member is arranged to follow the base strap to seal connection of the covering and the base strap.

In one embodiment, a roof covering system includes at least two ridge post members, a tarp at least two cables, at least two poles, at least two pole attachment members, and at least two winches. Each ridge post member may include a base configured to attach to a ridge of a roof, a head member; and a post having a bottom end and a top end, the bottom end secured to the base, and the top end secured to the head member. The tarp may have a top edge and a bottom edge, and connection points disposed near the top and bottom edges, wherein the head members are configured to attach to the connection points near the top edge. The cables may be configured to attach to the connection points near the bottom edge of the tarp. The poles may be configured to each guide a respective cable. The two pole attachment members may each be configured to attach a respective pole to a location on the roof below the ridge of the roof. The winches may each be configured to apply tension to a respective cable, thereby suspending the tarp above the roof.

Disclosed is a concrete curing blanket including a film layer, a differential hydrophobic/hydrophillic layer and a gel layer interposed therebetween.

A concrete curing blanket includes an absorbent sheet having a wicking layer, super absorbent materials, and a tissue layer, which are laminated together to form the absorbent sheet. The absorbent sheet is sized for being spread over a curing concrete slab. A vapor barrier is bonded to the tissue layer of the absorbent sheet to inhibit evaporation from the concrete curing blanket, and includes a plurality of perforations.
