Ammunition boxes may be equipped with a cohesive and adhesive shell restraining overlay adapted to restrain ammunition shells in a stabilized position. The shell restraining overlay provides sufficient adhesiveness to restrain a housed ammunition shell at a desired shell position, but allows for relatively effortless shell release without creating excessive movement or noise. The stabilizing overlay also stabilizes the shells from inadvertent spillage from the ammunition box.

Deck repair blocks, deck repair methods, and repaired decks are enabled. For example, a deck repair block can comprise: a saddle portion configured to receive a joist, a first recessed portion configured to receive a first deck board, and a second recessed portion configured to receive a second deck board.

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 subfloor leveling assembly for leveling floor paneling on a subfloor includes a subfloor of a floor system in a building. A leveling compound is provided that comprises wood particles that are mixed with a fluid resin. The leveling compound is spread over the subfloor to completely cover the subfloor thereby facilitating the leveling compound to settle through gravity. In this way the leveling compound defines a level surface on the subfloor. Floor paneling is provided and the floor paneling is positionable on the leveling compound when the leveling compound is spread over the subfloor. In this way the floor paneling is leveled on the subfloor.

A road structure reconstructed from large-scale independent underground garage and a construction method, which solves the problem of a newly constructed urban expressway passing through large underground space. The technical point is a construction method for the road structure reconstructed from large-scale independent underground garage, including the following steps: S100: segmentation for the garage, S200: preparation before construction: the materials and equipment required for construction are transported to the site, and the construction site is cleaned, S300: reconstruction for the front section, S400: reconstruction for the middle section, S500: reconstruction for the rear section. The inventiveness of the present disclosure is the application of segmentation construction, the front section is completely obsoleted, a transition section is provided at the middle, and the design of the rear section adopts a double-deck road, thus the original underground garage structure is fully utilized.

A floor panel having a heating element disposed therein, the floor panel having at least two abutments for operationally coupling the panel to adjacent panels. Electrical contacts are disposed on complementary abutments or abutment walls and busbars electrically couple between complementary contacts of opposing abutments such that, when adjacent floor panels are laid together to form a floor or a portion thereof, the busbars are able to feed power to heating elements disposed in the panel. The panel have sealants and/or adhesives which protect at least one contact from fluids. Also disclosed are connector bars, adapters, and switching and protection arrangements, and optional constructions for inter-panel connectors.

A portable apparatus and method for cutting linear trenches in a concrete ground surface includes two bars extending in parallel spaced relation along the concrete with an elongated track removably fastened and extending orthogonally thereto. A trolley supporting a motor-driven cutting wheel is movably engaged with the track. A depth adjuster alternately lowers and raises the cutting wheel to engage and disengage the concrete while the trolley follows contours of the concrete to cut a kerf of uniform depth. The track is selectively movable to spaced locations along the lengths of the two bars to cut a first plurality of parallel kerfs in a first direction. The apparatus is rotatable about a vertical axis to cut a second plurality of parallel kerfs oriented in a second direction at a predetermined angle, e.g., 90 degrees, to the first direction, to form a simulated tile pattern in the concrete.

A method for repairing surface damage includes taking an image of a non-damaged area of the surface, selecting a repair patch having an outward surface adapted to be directly printable using an Ink Jet, Laser, or other household printer; printing the image onto the repair patch, and applying the repair patch over the damaged area. This repair method may use a patch with a self-adhesive lower surface for easy application. This method can further include placing a center reinforcement patch over the surface damage before applying the repair patch. The Center reinforcement patch may provide an adhesive on the lower surface.
