Fiber reinforced polymer composite bridge deck of tubular profile having vertical snap-fit connection
First Claim
1. A fiber reinforced polymer composite deck module comprising:
- an upper plate having an upper extension at one side, a lower plate having a lower extension at one side opposite to the side of the upper plate, and a web disposed between the upper and lower plates to form a plurality of divisional portions of polygonal tubular cross-sectional shape between the upper and lower plates,wherein at one side, a first interlocking piece protrudes downward at the end of the extension of the upper plate and a second interlocking piece protrudes downward at a lower outer surface of the web, and at the other side, a third interlocking piece protrudes upward at an upper outer surface of the web and a fourth interlocking piece protrudes upward at the end of the extension of the lower plate,wherein the first interlocking piece is disposed further from the web than the second interlocking piece and the fourth interlocking piece is disposed further from the web than the third interlocking piece,wherein upon assembling the deck modules with each other, the first and the second interlocking pieces of one module are detachably and mechanically snap-fit coupled to the third and the fourth interlocking pieces of another module, andwherein the interlocking pieces coupled to each other have protrusions with a shape corresponding to each other configured for mutual mechanical engagement so that neighboring deck modules are detachably and mechanically snap-fit coupled in a vertical direction to each other to form a deck.

Abstract
A fiber reinforced polymer composite deck module is used to form a deck constructed by assembling the deck modules. The deck module comprising an upper plate having an upper extension at its one side, a lower plate having a lower extension at its one side opposite to the side of the upper plate, and an interlink plate therebetween, forming therein a plurality of divisional portions of polygonal tubular cross-sectional shape, wherein at one side, including a first interlocking piece protruded downward at the end of the extension of the upper plate and a second interlocking piece protruded downward at a lower outer surface of the interlink plate, and at the other side, including a third interlocking piece protruded upward at an upper outer surface of the interlink plate and a fourth interlocking piece protruded upward at the end of the extension of the lower plate, wherein upon assembling the deck modules with each other, the first and second interlocking pieces of one module are detachably and mechanically snap-fit coupled to the third and fourth interlocking pieces, respectively, of the other module, and wherein the interlocking pieces coupled to each other have protrusions with a shape corresponding to each other for mutual mechanical engagement so that neighboring deck modules are detachably and mechanically snap-fit coupled in a vertical direction to each other to form a deck.

4. A bridge deck constructed by assembling fiber reinforced polymer composite deck modules side by side,
wherein each deck module comprises an upper plate having an upper extension at one side, a lower plate having a lower extension at one side opposite to the side of the upper plate, and an web disposed between the upper and lower plates to form a plurality of divisional portions of polygonal tubular cross-sectional shape between the upper and lower plates, wherein each deck module includes, at one side, a first interlocking piece protruding downward at the end of the extension of the upper plate and a second interlocking piece protruding downward at a lower outer surface of the web, and at the other side, a third interlocking piece protruding upward at an upper outer surface of the web and a fourth interlocking piece protruding upward at the end of the extension of the lower plate, wherein the first interlocking piece is disposed further from the web than the second interlocking piece and the fourth interlocking piece is disposed further from the web than the third interlocking piece, wherein upon assembling the deck modules with each other, the first and the second interlocking pieces of one module are detachably and mechanically snap-fit coupled to the third and the fourth interlocking pieces, respectively, of another module, and wherein the interlocking pieces have protrusions with a shape corresponding to each other configured for mutual mechanical engagement so that a deck module is detachably and mechanically snap-fit coupled in a direction perpendicular to the upper plate to a neighboring deck module to form the deck.
