A building panel is provided. The building panel includes an exterior wall portion, an interior wall portion, a pair of opposing sidewalls, a first end portion and an opposite second end portion. The pair of opposing sidewalls spacing apart the interior wall portion from the exterior wall portion to define a cavity therebetween. The exterior wall portion, the interior wall portion and the pair of opposing sidewalls are arcuate in shape to define the building panel. The first end portion has a slip lock slot extending between the pair of opposing sidewalls. The second end portion has a slip lock tab member extending between the pair of opposing sidewalls. The slip lock slot of the building panel is configured to receive the slip lock tab member of a second building panel to adjoin the first and second building panels in a continuous fashion.

In some embodiments, a building block includes alignment elements that interlink with a similar block with a positional offset. For example, the positional offset may be linear and/or rotational. For example, the second cinder block may be rotated with respect to the first block on which it is supports. Optionally, protrusions from the top of the block are positioned to interlink to the vertical slots at a fixed offset between the blocks. Optionally, the protrusions are formed by channels on a mold and/or a mold head. In some embodiments, a structure may be built stacked blocks. Optionally, a decorative face is configured to form a continuous decorated surface across offset blocks. In some embodiments a building block includes a calibration feature. For example, the block may include a ridge on the top of the block that may be shaved and/or ground to adjust the height of the block.

An apparatus guides first and second assembly components into a predetermined configuration, each assembly component including an opening. When the assembly components are aligned into the predetermined configuration, their openings align to define a cavity for receiving a stepped dowel to fasten the components together. The guiding apparatus includes a stepped dowel member having successively-smaller dowel sections, and a collar member floating around the base of the stepped dowel member. The stepped dowel member tip can be passed through the first assembly component opening and inserted into the second assembly component opening, drawing the components into the predetermined configuration. When the components are aligned into the predetermined configuration, the collar member engages the first assembly component opening and the stepped dowel member engages the second assembly component opening. The guiding apparatus can be disengaged, freeing the dowel-receiving cavity to accept a stepped dowel for fastening the assembly components together.

The present disclosure relates to a field-type negative pressure isolation room system including main facilities necessary for constructing a negative pressure isolation room defined by the legal regulations, wherein the main facilities are manufactured in a plant in a modular way, so these modular facilities are usually stored in a warehouse, etc., and are installed in an outdoor site such as a parking lot, playground, vacant lot, and the like in case of emergency to utilize as a negative pressure isolation room, and these modular facilities are disinfected and dismantled during demolition and stored in the warehouse again, whereby these modular facilities can be used repeatedly regardless of the number of times of use, and can be quickly constructed and dismantled.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

A wall is made with the aid of drywall panels and a background. The drywall panels are provided with edge coupling profiles on their edges, which are arranged to be secured to the background and, subsequently, coupled to each other. The drywall panels may also be provided with a rear coupling profile. The drywall panels can be hooked together or coupled to each other by means of transverse sliding. The edge coupling profiles may also comprise anti-adhesive extensions, forming anti-adhesive edge areas at the front side of the drywall panel on which stucco mass does not adhere. The measures according to the invention are intended to provide drywall panels which, after use, can be disassembled easily and cleanly so that the drywall panels can be reused as drywall panels, resulting in that the environment is not burdened with gypsum waste caused by damaged, broken and destroyed drywall panels.

A method of manufacturing a kit for a cold storage room includes the following steps: determining one or more dimensions of the cold storage room; providing continuously manufactured insulation panels, cut to have a length based on the dimensions of the cold storage room, and having alignment structures formed thereon; cutting one or more of the continuously manufactured insulation panels to have a width based on the dimensions of the cold storage room and to form one or more joints; forming connecting structures on one or more of the continuously manufactured insulation panels, the connecting structures configured to form one or more joints; and providing connection hardware configured to mate with the connecting structures and to form one or more joints.

A connector configured to couple plural wall elements like wall panels, the connector including a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position; a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and a housing for the coupling or the block, the housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position, wherein the housing includes a first housing half and a second housing half, wherein the housing pass through opening is closed by a cover wall against a pass through of the locking hook.
