Modular paneled structure having connective means to prevent gap opening and disconnection

A modular paneled structure having connective means to prevent gap opening and disconnection, comprising each of the following:

• a main panel with a symmetric profile which has a closed-sectional portion in the middle and open-sectional portions at each end,
• wherein the closed-sectional portion comprises an upper plate, a lower plate, and inner webs, connecting the upper and lower plates to form a plurality of divisional cells of polygonal tubular cross-sectional shapes between the upper and lower plates,
• wherein the open-sectional portion comprises an extended lower plate, an upward outer web at the end of the extended lower plate, and an outermost inner web which is shared in common with the closed-sectional portion;
• a cover panel with a symmetric profile of an open-sectional portion which interconnects two side-by-side main panels, where the cover panel closes the open-sectional portions of the two side-by-side main panels,
• wherein the cover panel comprises an upper plate, two downward outer projected portions which each project from the upper plate at each end, and two downward inner projected portions in the mid-section of the cover panel in-between the outer projected portions which project from the mid-section of the upper plate;
• and
• a tensioning member which interconnects and pre-tensions the main panels that are placed side by side,
• wherein the tensioning member is anchored at the outermost inner web of each main panel placed side-by-side and passes through a slit and an anchorage hole which are formed in the outermost inner web and upward outer web of the main panel, and exerts pre-tensioning force in-between the two main panels,
• wherein the tensioning member can be re-tensioned if necessary upon disassembling the cover panel;
• and
• consequently, forms an assembled paneled structure with all these connective means.
