Summary of the invention
The purpose of this utility model be deficiency in order to solve above-mentioned technology and a kind of structure designed more firmly bridge stitch continuously.
A kind of bridge designed by the utility model stitches continuously, comprise two pieces, the left and right beam slab of bridge, gap is provided with between two pieces of beam slabs, gap filling has froth bed, bridge deck concrete layer is provided with above beam slab, it is characterized in that also comprising two piece of first steel plate in left and right, beam slab is all provided with embedded ribs, described first steel plate is arranged on corresponding beam slab and embedded ribs on beam slab inserts this first steel plate, described first steel plate is provided with notch near the one end in gap, the water proof rubber bar sealed in described gap is installed with in the notch of two piece of first steel plate in left and right, described first steel plate is provided with step away from the one end in gap, steel fiber concrete block is provided with between the first steel plate and bridge deck concrete layer, one piece of second steel plate is provided with above the steel plate of two piece first, left and right, this bridge stitches continuously and also comprises elasticity concrete layer, elasticity concrete layer to be located between the two pieces of steel fiber concrete blocks in left and right and to be positioned at above described second steel plate, and described bridge deck concrete layer, steel fiber concrete block are concordant with their surface of elasticity concrete layer and watered bitumen layer above them.
Above-mentioned a kind of bridge stitches continuously, its suture body is sealed by the second steel plate and above the second steel plate, is provided with elasticity concrete layer, second steel plate mainly carries the weight above gap, when bridge beam slab is stressed or the time of expanding with heat and contract with cold produce deformation time, second steel plate can do certain movement above two piece of first steel plate, and be filled in above the second steel plate and the elasticity concrete layer of both sides has elasticity, deformation can be produced along with the mobile of the second steel plate, thus coordinate the flexible of bridge beam slab; Second steel plate is steel matter, sound construction, and bearing capacity is strong, not cracky, and the second steel plate and the mutual frictional force of the first steel plate is less makes them do relative movement.
It should be noted that: steel fiber concrete, elasticity concrete are all the state of the art, are well known to those skilled in the art, specifically do not describe in detail.
As preferably: the notch on described first steel plate is upper and lower two, and described water proof rubber bar is also upper and lower two, and such scheme can improve waterproof effect further.
Bridge designed by the utility model stitches continuously, and its beneficial effect is: sound construction, not cracky, and maintenance cycle is long.
