A kind of water proof type bridge expanssion joint designed by the utility model, comprise the beam slab that two pieces, left and right has gap each other, beam slab is provided with bridge deck concrete layer, be supercrust above bridge deck concrete layer, between beam slab, be filled with froth bed, the inside edge of each block beam slab is all provided with shaped steel, elasticity concrete layer is provided with between described shaped steel and bridge deck concrete layer, be provided with the reinforcing bar imbedding elasticity concrete layer outside described shaped steel, described shaped steel has base, and described beam slab is provided with the outer end of embedded ribs through described base; The inner, described base is provided with and staggered is provided with protuberance and depressed part, and wherein the protuberance of a block-type steel is relative with the depressed part of another block-type steel and have gap each other; Between the block-type steel of left and right two, be provided with upper and lower two-layer water proof rubber layer, the water proof rubber layer being positioned at upper strata is installed on the inwall of shaped steel, and the water proof rubber layer being positioned at lower floor is arranged on the inner top on described base.
As preferably:
The water proof rubber layer inside being positioned at lower floor has hollow structure.
Water proof type bridge expanssion joint designed by the utility model, its beneficial effect is: what fill between bridge deck concrete layer and shaped steel is elasticity concrete layer, the high resilience while that elasticity concrete Rotating fields being firm, can better shaped steel be cast on beam slab, when shaped steel is by vehicle spreading, elasticity concrete layer can produce deformation, to play the effect of buffering and suction external force, prevent junction between shaped steel and bridge deck concrete layer damaged, prevent supercrust generation crackle.On the other hand, upper and lower two-layer water proof rubber layer is provided with between the block-type steel of left and right two, form two pass waterproof, water resistance is better, and the water proof rubber layer being positioned at upper strata is installed on the inwall of shaped steel, in hanging shape as prior art, and the water proof rubber layer of lower floor is arranged on the inner top on described base, arrange more firm, its water proof rubber layer compared to upper strata more not cracky, can play good waterproof action; Being provided with in the inner, shaped steel base interlocks is provided with protuberance and depressed part, and such structure does not affect the flexible of bridge expanssion joint on the one hand, can arrange again the water proof rubber layer of lower floor simultaneously, thus play the effect of waterproof.Moreover beam slab is provided with the outer end of embedded ribs through described base, like this when constructing, is convenient to shaped steel to fix, and can strengthen mutual bonding strength, make structure more firm, construct more convenient simultaneously.Water proof type bridge expanssion joint designed by the utility model, all has stronger practicality when newly-built construction and repairing.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 water proof type bridge expanssion joint;
Fig. 2 is embodiment 1 water proof type bridge expanssion joint shaped steel top view.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, 2, water proof type bridge expanssion joint described by the present embodiment, comprise the beam slab 1 that two pieces, left and right has gap each other, beam slab 1 is provided with bridge deck concrete layer 2, it is supercrust 3 above bridge deck concrete layer 2, froth bed 4 is filled with between beam slab 1, the inside edge of each block beam slab 1 is all provided with shaped steel 5, elasticity concrete layer 6 is provided with between described shaped steel 5 and bridge deck concrete layer 2, the reinforcing bar 7 imbedding elasticity concrete layer 6 is provided with outside described shaped steel 5, it is characterized in that described shaped steel 5 has base 8, described beam slab 1 is provided with the outer end of embedded ribs 13 through described base 8; The inner, described base 8 is provided with and staggered is provided with protuberance 9 and depressed part 10, and wherein the protuberance 9 of a block-type steel 5 is relative with the depressed part 10 of another block-type steel 5 and have gap each other; Upper and lower two-layer water proof rubber layer 11 is provided with between left and right two block-type steel 5, the water proof rubber layer 11 being positioned at upper strata is installed on the inwall of shaped steel 5, the water proof rubber layer 11 being positioned at lower floor is arranged on the inner top on described base 8, and water proof rubber layer 11 inside being positioned at lower floor has hollow structure 12.The effect of hollow structure 12 is in order to the water proof rubber layer 11 of lower floor can produce deformation when stretching in shrinkage joint, certainly, because water proof rubber layer 11 has elasticity, therefore also can not arrange hollow structure 12.
