A construction element includes a first wall, and a second wall. The walls are arranged at a distance from one another, forming a space wherein at least one non-concrete composite bar is arranged. Concrete is arranged in the space between the first wall, the second wall, and the composite bars.

A container comprising a threshold assembly. The threshold assembly comprises an outer end plate, a horizontal connecting member and a middle connecting member. The outer end plate comprises a horizontal portion and a vertical portion; the horizontal member connects to a floor of the container; and the middle member connects to the plate and the horizontal member, wherein one end of the middle member extends to the intersection of the horizontal portion and the vertical portion of the plate; an opening and a clamping groove at the other end of the middle member; and an inserting portion at one end of the horizontal member for inserting into the clamping groove through the opening to connect the horizontal member and the middle member. When force is applied to the threshold assembly, gaps among the horizontal and middle members and the plate are sealed, preventing liquids from causing steel corrosion.

A reversibly foldable freight container having a front wall and a rear wall, where the front wall includes front wall corner posts, a front door hinge on at least one of the front wall corner posts and a front door joined to the front door hinge. The rear wall includes rear wall corner posts, locking rods, a hinge on the rear wall corner posts and a rear wall door joined to the hinge. The front door can be positioned inside a volume defined by the reversibly foldable freight container. The locking rods of the rear door are shortened to position cams mounted on the locking rods directly adjacent the rear door, where the locking rods, cams and the rear door can pass through an end frame of the rear wall to position the rear door of the rear wall inside the volume of defined by the reversibly foldable freight container.

A system for detecting human entry into a container using electromagnetic imaging to generate image maps of the container. The system includes a door monitor configured to detect an entry door open event associated with the container. The system uses one or more processors and a memory with instructions to generate a baseline image map of the container, detect an entry door open event with the door monitor associated with the container, generate a post entry door open event image map of the container, and compare the baseline image map generated before the entry door open event with image map generated after the entry door open event.

The present invention relates to a method of assembling a folding container. A base comprising a floor is provided, and at least two side panels are attached to the base. A rear panel is pivotally attached to the base, wherein the rear panel is operable to pivot between a folded position that contacts the floor and a vertically deployed position. A hinge block is attached to the base. A front panel comprising a front door is pivotally attached to the hinge block, wherein the front panel is operable to pivot between a folded position that contacts the front panel and a vertically deployed position.

A sulfur storage tank includes a bottom plate, an outer wall, and a cleanout door. The outer wall surrounds and is coupled to the bottom plate. The cleanout door is installed on the outer wall. The cleanout door includes an edge and a drain nozzle. The edge abuts the bottom plate. The drain nozzle is installed on the cleanout door. The drain nozzle defines a centerline offset from the edge. The drain nozzle is configured to gravity drain fluid from the sulfur storage tank.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A foldable container adjustable between an unfolded condition and a folded condition comprises a roof panel and an opposing base panel, a front panel and an opposing door panel which are each hingedly connected to solely the roof panel, a right side panel and an opposing left side panel, a right side roof skirt and an opposing left side roof skirt having disparate heights, a left side compound beam and a right side compound beam extending from the base panel, and a left side hinge-beam structure and a right side hinge-beam structure each having a hinge point and a skirt retaining portion. The right side panel and the left side panel are hingedly coupled to their respective hinge-beam structures at the hinge points. The hinge points lie in different horizontal planes. The hinge points lie within a midline of their respective side panel.

A modular shipping container apparatus having a base with two support portions each of having two substantially open top rectangular shaped spaces each having a bottom side, a left side and a right side and at least one set of base holes; at least one wheel assembly between the two substantially open top rectangular shaped spaces, the at least one wheel assembly having a substantially open bottom rectangular piece with at least one set of wheel assembly holes and at least one wheel with a center opening, the wheel assembly is retained between the two substantially open top rectangular shaped spaces by at least one bar through the at least one set of base holes, the at least one set of wheel assembly holes and the wheels; at least two tracks attached to the bottom interior of a shipping container for slidably receiving the at least one wheel assemblies.

A sliced assembly type container, manufacturing, stacking and transportation methods, and finished modules. The sliced assembly type container meets requirements of the ISO on a universal cargo container. The sliced assembly type container comprises a bottom finished module (1), two side finished modules (2, 3), two door finished modules (6, 7), a top finished module (5), and a front finished module (4). Adjacent modules are fixed by using a connection structure, and/or fixing glue, and/or welding, and/or another manner.
