A flooring system has at least one girder, a first joist coupled to a first side of the girder, and a second joist coupled to a second side of the girder. The flooring system further comprises a joist tightening system that has a first end coupled to the first joist and a second end coupled to the second joist, the joist tightening system pulls the first joist and the second joist toward the girder thereby tightening the first joist and the second joist.

Hygienic trays adapted to effectively restrain items under hygienic conditions are provided by equipping hygienic trays with an antipathogenic, cohesive and adhesive thermoset overlay provided in the form of an adhesive insert or tray coating. The overlay adhesively restrains emplaced items until manually removed from the overlay by the hygienic user while also providing an unexpected superior antipathogenic environment. The hygienic trays are particularly useful from hygienic applications wherein hygienic conditions and a need to stabilize trayed items against displacement are of a dominant concern. The tray may be of a simple platform design with or without a typical bordering rim which may be adapted for hand carriage or mounted onto another supportive structure.

A method and device for holding a subsurface layer of an elevated flooring portion of a floor structure at a distance from a subfloor in a vicinity of an opening in the flooring portion during a process of drying the floor structure. According to the invention there is provided at least one rod having a substantially perpendicularly angled end. The rod is inserted below the subsurface layer through the opening and the angled end of the rod is attached to an edge of a surface layer in the opening of the flooring portion in a manner that the rod supports the subsurface layer at said distance from the subfloor when the flooring portion is elevated.

A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A method and arrangement for drying a water damaged floor structure having a ventilated isolating layer below a concrete layer extending throughout an enclosed space, and the enclosed space having a tiled flooring over the concrete layer. An outlet opening is provided into the floor structure and to the isolating layer outside of an end of the enclosed space, the tiled flooring is heated by a heating source, and ambient air drawn by a suction source through the isolating layer and out of the outlet opening.

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.

The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre formed rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod's ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

An automatic wood flooring boards reparation device for applying and spreading filler over boards is provided, the device comprising an infeed unit, an outfeed unit and a filler applicator. The filler applicator applies filler over a top surface of the boards with a head comprising a main body, a spreading device and a bottom portion, each part comprising an opening for distributing filler over the board and an opening for securing a scrapper for spreading the applied filler. A tight seal is created between a filler applicator opening of the bottom portion and the top surface of the boards to avoid overspill of filler. A method for applying filler is also provided.

The present invention relates to a repairable clip and a deck fixing structure using the same. The present invention is characterized by a method for facilitating a method of fastening a middle part again when replacing same within the scope of constructing a deck and, more specifically, by a simple and convenient method for separating a rotary member for repair, which is integrated into the clip, mounting the same to the clip, positioning a new deck material, and thereafter fixing the replaced deck material to a deck assembly by rotating the rotary member with a simple tool, such as an Allen wrench. The present invention for repairing a constructed deck material to its original form with the performance of a clip itself is an invention first attempted in the world.

A flooring component comprising a main body portion defining a first major surface and a second major surface, a first extending portion that extends from the main body portion in a first direction, the first extending portion defining a third surface coplanar to at least a portion of the first major surface, and a second extending portion that extends from the main body portion in a second direction opposite the first direction, the second extending portion defining a fourth surface coplanar to at least a portion of the second major surface, wherein at least 60% of the main body portion, the first extending portion and the second extending portion is of a first material, the first extending portion comprises a female structure on a side of the first extending portion opposite the third surface, the second extending portion comprises a male structure on a side of the second extending portion opposite the fourth surface, the flooring component comprises, in a region of at least one of the female structure and the male structure, a resilient portion of a second material more pliable than the first material, and the female structure is of a shape that snappingly engages the male structure using a resilience of the resilient portion.
