Patent ID: 8438791

Claim:
A modular building removable coupling device for forming an explosion resistant, forced entry resistant, and/or ballistic resistant facility comprising: a. a first hollow square or rectangular tubing having a first hollow top side; b. a second hollow square or rectangular tubing having a second hollow top side; c. a sealing means disposed between the first hollow square or rectangular tubing and the second hollow square or rectangular tubing providing a weather resistant connection; d. a fastener centrally oriented to penetrate and connect the first hollow square or rectangular tubing to the second hollow square or rectangular tubing; e. a first roof plate secured to the first hollow square or rectangular tubing; f. a second roof plate secured to the second hollow square or rectangular tubing; g. a first roof cap side for connecting perpendicularly to the first roof plate; h. a second roof cap side for connecting perpendicularly to the second roof plate; i. a roof cap top integrally connected between the first roof cap side and the second roof cap side above the first roof plate and the second roof plate; j. a first side sealing tube removably secured to an inner side of the first roof cap side using a first side fastener and non-removably secured to the first roof plate; and k. a second side sealing tube removably secured to an inner side of the second roof cap side using a second side fastener and non-removably secured to the second roof plate, wherein the modular building removable coupling device connects a first explosion resistant, forced entry resistant, and/or ballistic resistant housing module to a second explosion resistant, forced entry resistant, and/or ballistic resistant housing module, forming the explosion resistant, forced entry resistant, and/or ballistic resistant facility.
