A kind of bridge floor concrete structure, comprise the beam slab of bridge, beam slab joint is provided with gap, described beam slab is provided with ordinary concrete layer, cover plate is provided with above described gap, be provided with elastic concrete layer above described cover plate, be provided with steel fibrous concrete layer between described elastic concrete layer and ordinary concrete layer, described elastic concrete layer, steel fibrous concrete layer are concordant with ordinary concrete layer top and be provided with supercrust above them; Described elastic concrete layer is divided into upper, middle and lower three layers, is respectively the first elastic concrete layer, the second elastic concrete layer and three layers, the 3rd elastic concrete layer; Be provided with foam filled block between described 3rd elastic concrete layer and the steel fibrous concrete layer in left side, between described second elastic concrete layer and the steel fibrous concrete layer on right side, be also provided with foam filled block.
It should be noted that: steel fibrous concrete and elastic concrete can be cast-in-place, also be commercially available, ordinary concrete is then this area routine techniques, namely ordinary concrete is the concrete that we commonly use under construction, apparent density is 1950 ~ 2500Kg/ cubic meter, mainly gathering materials formulated for mainly with sand, stone, is concrete species the most frequently used in civil engineering.
Above-mentioned bridge floor concrete structure, what arrange above gap is the elastic concrete layer that elastic deformation ability is stronger, the two-layer elastic concrete end being positioned at bottom is in addition all open, namely all contacted with steel fibrous concrete layer by foam filled block, foam filled block can be compressed when the deformation of elastic concrete layer, therefore can further improve the elastic deformation performance of elastic concrete layer lower two layers, can adapt to better beam slab stressed or expand with heat and contract with cold and produce flexible, not cracky; Steel fibrous concrete layer intensity is higher, can improve bulk strength.
Improvement as such scheme:
Also comprise the frame-shape rib of lower openings, described frame-shape rib is positioned at elastic concrete layer and steel fibrous concrete layer simultaneously, and described foam filled block is positioned at described frame-shape rib;
Described first elastic concrete layer, between the second elastic concrete layer and the 3rd elastic concrete layer, be provided with adhesive layer;
The Thickness Ratio of described first elastic concrete layer, the second elastic concrete layer and the 3rd elastic concrete layer is 1:1:1;
Described supercrust is cement road surface layer or blacktop;
Described cover plate is stainless steel;
All steel mesh reinforcement is provided with in described first elastic concrete layer, the second elastic concrete layer and the 3rd elastic concrete layer;
Bridge floor concrete structure designed by the utility model, its beneficial effect is: the spreading repeatedly can bearing vehicle better, can adapt to beam slab better and expand with heat and contract with cold on the impact of bridge floor generation, longer service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment Bridge 1 beam bridge floor concrete structure;
Fig. 2 is the enlarged drawing at A place in Fig. 1;
Fig. 3 is the structural representation of embodiment Bridge 2 beam bridge floor concrete structure.
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, bridge floor concrete structure described by the present embodiment, comprise the beam slab 1 of bridge, beam slab 1 joint is provided with gap 2, described beam slab 1 is provided with ordinary concrete layer 3, stainless steel cover plate 4 is provided with above described gap 2, elastic concrete layer 5 is provided with above described cover plate 4, be provided with steel fibrous concrete layer 6 between described elastic concrete layer 5 and ordinary concrete layer 3, described elastic concrete layer 5, steel fibrous concrete layer 6 are concordant with ordinary concrete layer 3 top and above them, be provided with cement road surface layer 7; Described elastic concrete layer 5 is divided into upper, middle and lower three layers, is respectively the first elastic concrete layer 51, second elastic concrete layer 52 and 53 3 layers, the 3rd elastic concrete layer; Be provided with foam filled block 8 between described 3rd elastic concrete layer 53 and the steel fibrous concrete layer 6 in left side, between described second elastic concrete layer 52 and the steel fibrous concrete layer 6 on right side, be also provided with foam filled block 8.
Above-mentioned bridge floor concrete structure, what arrange above gap 2 is the elastic concrete layer that elastic deformation ability is stronger, the two-layer elastic concrete end being positioned at bottom is in addition all open, namely all contacted with steel fibrous concrete layer 6 by foam filled block 8, foam filled block 8 can be compressed when the deformation of elastic concrete layer, therefore can further improve the elastic deformation performance of elastic concrete layer lower two layers, can adapt to better beam slab 1 stressed or expand with heat and contract with cold and produce flexible, not cracky; Steel fibrous concrete layer intensity is higher, can improve bulk strength.
Through test, breakage when this bridge floor concrete structure uses concentrates on the part of the 3rd elastic concrete layer 53, and in this case, only need clear up to lay equal stress on during reparation and build elastic concrete layer, elastic concrete layer curing time is shorter, and construction more for convenience.
Bridge floor concrete structure described by the present embodiment, its beneficial effect is: the spreading repeatedly can bearing vehicle better, can adapt to beam slab better and expand with heat and contract with cold on the impact of bridge floor generation, longer service life.
In above-described embodiment, can also adhesive layer be provided with between described first elastic concrete layer 51, second elastic concrete layer 52 and the 3rd elastic concrete layer 53, to increase the connection tight ness rating between each layer, certainly not arrange and be also fine; The Thickness Ratio of described first elastic concrete layer 51, second elastic concrete layer 52 and the 3rd elastic concrete layer 53 is 1:1:1, significantly, can also be other ratio;
Embodiment 2:
As shown in Figure 3, bridge floor concrete structure described by the present embodiment, as different from Example 1: the frame-shape rib 9 also comprising lower openings, described frame-shape rib 9 is positioned at elastic concrete layer 5 and steel fibrous concrete layer 6 simultaneously, and described foam filled block 8 is positioned at described frame-shape rib 9.Frame-shape rib 9 can improve the bonding strength between elastic concrete layer 5 and steel fibrous concrete layer 6, on the other hand, due to frame-shape rib 9 lower openings, frame-shape rib 9 can slightly open and receipts are disturbed, also can produce deformation during two-layer elastic concrete layer generation deformation below thereupon, guarantee the deformability of elastic concrete layer 5.
Certainly, in order to improve intensity further, following improvement can also be adopted: be namely all provided with steel mesh reinforcement in described first elastic concrete layer 51, second elastic concrete layer 52 and the 3rd elastic concrete layer 53.
