Description
Technical field
The utility model relates to a kind of freely-supported bridge, especially a kind of novel bridge floor continuous structure of freely-supported bridge.
Background technology
The bridge floor continuous structure of freely-supported bridge is two across the seam crossing between beam, and under automobile and the temperature difference expand with heat and contract with cold repeated action, common generation crack, does not disconnect exhibition, causes the destruction of bridge asphalt pavement and affects road-ability.Be hollow shape below its prestressed concrete section of bridge floor continuous structure of Chinese patent ZL201120232391.1 freely-supported bridge, prestressed concrete section bears larger power, after Reusability, easily causes depression, and practical effect is not good.
Owing to there is such problem, so be necessary to improve the bridge floor continuous structure of existing freely-supported bridge.
Summary of the invention
The purpose of this utility model is deficiency in order to solve above-mentioned technology and the novel bridge floor continuous structure of the freely-supported bridge of a kind of long service life designed.
The novel bridge floor continuous structure of a kind of freely-supported bridge designed by the utility model, comprise two pieces, the left and right beam slab of freely-supported bridge, gap is had between beam slab, foam insert is provided with in gap, beam slab is provided with bridge deck concrete layer, be provided with the precast concrete block watered by elastic concrete between bridge deck concrete layer on the beam slab of two pieces, left and right, in precast concrete block, have reinforcing bar; Above precast concrete block, be provided with elasticity concrete layer, above elasticity concrete layer and bridge deck concrete layer, be provided with supercrust; Metal slide block is interval with in precast concrete block lower end, beam slab is interval with the metal fixed block that position is fixing, described metal slide block is slidably arranged on above metal fixed block, between two metal fixed blocks near gap, be provided with water proof rubber bar; Steel fiber concrete is provided with away from the below of that one end in gap at precast concrete block.
As preferably:
Described metal slide block is inverted T-shaped part with holes, and described reinforcing bar is through this metal slide block;
Described metal fixed block is arranged on the top of the embedded ribs on beam slab;
The novel bridge floor continuous structure of the freely-supported bridge designed by the utility model, its beneficial effect is: automobile and the temperature difference are expanded with heat and contract with cold under repeated action, beam slab produces mobile, precast concrete block is watered by elastic concrete, can produce flexible thereupon, bridge floor is not easily broken, and the metal slide block below it can slide on metal fixed block with the flexible of precast concrete block, formed and effectively support, so not only absorb the impact that beam slab deformation produces, support effect well can be played simultaneously; And precast concrete block lower surface does not directly contact with beam slab, but by metal slide block and metal fixed block, frictional force is little, is convenient to the deformation of precast concrete block, and precast concrete block can be made in advance, to shorten the construction period, and rush to repair, curing period.On the other hand, elasticity concrete layer is positioned at above precast concrete block, also can produce flexible, can available protecting supercrust, makes it not break, can increase the service life.

Fig. 2 is the enlarged drawing at A place in Fig. 1;
Fig. 3 is the schematic diagram of embodiment 1 metal slide block;
In figure: beam slab 1, gap 2, bridge deck concrete layer 3, precast concrete block 4, reinforcing bar 5, elasticity concrete layer 6, supercrust 7, metal slide block 8, metal fixed block 9, water proof rubber bar 10, steel fiber concrete 11, embedded ribs 12, foam insert 13
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, the novel bridge floor continuous structure of the freely-supported bridge described by the present embodiment, comprise two pieces, the left and right beam slab 1 of freely-supported bridge, gap 2 is had between beam slab 1, foam insert 13 is provided with in gap 2, beam slab 1 is provided with bridge deck concrete layer 3, is provided with the precast concrete block 4 watered by elastic concrete, has reinforcing bar 5 in precast concrete block 4 between the bridge deck concrete layer 3 on the beam slab 1 of two pieces, left and right; Above precast concrete block 4, be provided with elasticity concrete layer 6, above elasticity concrete layer 6 and bridge deck concrete layer 3, be provided with supercrust 7; Metal slide block 8 is interval with in precast concrete block 4 lower end, beam slab 1 is interval with the metal fixed block 9 that position is fixing, described metal slide block 8 is slidably arranged on above metal fixed block 9, between two metal fixed blocks 9 near gap 2, be provided with water proof rubber bar 10; Steel fiber concrete 11 is provided with away from the below of that one end in gap 2 at precast concrete block 4.Wherein, described metal fixed block 9 is arranged on the top of the embedded ribs 12 on beam slab 1.
It should be noted that: elastic concrete is prior art, is commercially available, as Zhejiang, Ke Bo stabilization works company sells with regard to flexible concrete.
The novel bridge floor continuous structure of the freely-supported bridge described by the present embodiment, its beneficial effect is: automobile and the temperature difference are expanded with heat and contract with cold under repeated action, beam slab 1 produces mobile, precast concrete block 4 is watered by elastic concrete, can produce flexible, and the metal slide block 8 below it can slide on metal fixed block 9, is formed and effectively supports with the flexible of precast concrete block 4 thereupon, so not only absorb the impact that beam slab 1 deformation produces, support effect well can be played simultaneously; And precast concrete block 4 lower surface does not directly contact with beam slab 1, but by metal slide block 8 and metal fixed block 9, frictional force is little, be convenient to the deformation of precast concrete block 4, precast concrete block 4 can be made in advance, to shorten the construction period, and repairing, curing period.On the other hand, elasticity concrete layer 6 is positioned at above precast concrete block 4, also can produce flexible, can available protecting supercrust 7, makes it not break, can increase the service life.
Embodiment 2:
As shown in Figure 3, the novel bridge floor continuous structure of the freely-supported bridge described by the present embodiment, as different from Example 1: described metal slide block 8 is inverted T-shaped parts with holes, described reinforcing bar 5 is through this metal slide block 8; The bonding strength of metal slide block 8 and precast concrete block 4 can be improved.
Above-described embodiment is only to design of the present utility model explanation for example, and significantly, the protection domain of this patent is not limited to above-described embodiment.
The various equivalent modifications or supplementary that those skilled in the art do above-described embodiment, all should fall into the protection domain of this patent.
