Description
Technical field
The utility model relates to bridge deck structure field, relates in particular to a kind of simply supported girder bridge bridge floor continuous structure.
Background technology
Simply supported girder bridge bridge floor continuous structure refers to adjacent two does not establish shrinkage joint between across simply supported beam, but bridge deck are connected as a single entity along through thickness or segment thickness scope, make porous simply supported girder bridge can keep the mechanical characteristic of simply supported girder bridge, continuous runway can be provided again, make simply supported girder bridge possess the superiority such as driving that continuous girder bridge just has is steady, comfortable.Not only simple structure, the easy construction of simply supported girder bridge bridge floor continuous structure, and cost is low, thereby be widely applied in Short/Medium Span Bridge.
But, simply supported girder bridge bridge floor continuous structure is positioned at girder rotation, the flexible maximum position of beam body, stressed complexity, in addition the deficiency existing in design, work progress, and the impact of overload of vehicle in bridge operation process, the situation such as transfinite, bridge is come into operation after soon the continuous position of bridge floor just there will be concrete cracking phenomenon.With the increase of service time, cracking position can develop into the more serious disease forms such as transverse crack, hole groove gradually, and then the destruction that causes bridge floor asphalt concrete pavement layer, has a strong impact on the normal use of bridge, infringement road-ability, and may jeopardize traffic safety.
Utility model content
For above-mentioned technical problem, the utility model has been designed and developed a kind of simply supported girder bridge bridge floor continuous structure, and object is to provide a kind of simple in structure, reasonable in design, easy construction, can guarantee the continuous indehiscent simply supported girder bridge bridge floor continuous structure of bridge floor.
The technical scheme that the utility model provides is:
A kind of simply supported girder bridge bridge floor continuous structure, comprising:
Beam body, two adjacent one end of beam body are provided with the continuous preformed groove of bridge floor;
Bridge floor continuous structure layer and reinforced concrete pavement layer, it is all mated formation at adjacent two beam body end faces, described bridge floor continuous structure layer is mated formation at the continuous preformed groove end face of described bridge floor and is extended to both sides, described reinforced concrete pavement layer is mated formation in bridge floor continuous structure layer both sides, the continuous preformed groove of the bonding surface described bridge floor of the distance edge 300～800mm of described bridge floor continuous structure layer and reinforced concrete pavement layer;
Asphalt concrete pavement layer, it is mated formation at described bridge floor continuous structure layer and reinforced concrete pavement layer end face.
Preferably, in described simply supported girder bridge bridge floor continuous structure, described bridge floor continuous structure layer adopts high ductility fiber reinforced cement-based composite material.
Preferably, in described simply supported girder bridge bridge floor continuous structure, the both sides of described bonding surface arrange multiple vertical binding reinforcements.
Preferably, in described simply supported girder bridge bridge floor continuous structure, described multiple vertical binding reinforcement buried depths are not less than 10 times of vertical binding reinforcement diameters, and longitudinal pitch is not more than 300mm.
Preferably, in described simply supported girder bridge bridge floor continuous structure, between described bridge floor continuous structure layer and asphalt concrete pavement layer, be provided with waterproofing course.
In simply supported girder bridge bridge floor continuous structure described in the utility model, by the bonding surface of high ductility fiber reinforced cement-based composite material bridge floor continuous structure layer and reinforced concrete pavement layer by the continuous preformed groove of bridge floor edge the distance to two side shifting 300～800mm, and multiple vertical binding reinforcements are set in bonding surface both sides, greatly reduce near the stress of bonding surface, prevent that bridge floor continuous structure from ftractureing along bonding surface place.Carry out after above-mentioned two improvement, Latent destruction position is positioned at bridge floor continuous structure middle part, the i.e. position of bridge floor continuous modification maximum.High ductility fiber reinforced cement-based composite material has a series of good characteristics such as the tensile strength higher than ordinary concrete, anti-fatigue performance, freezing and thawing performance, abrasion resistance, toughness, acid and alkali-resistance and shock resistance, its ultimate tensile strength can reach 5～6%, is the hundred times of ordinary concrete.Meanwhile, this material has also shown the innoxious dispersibility in excellent crack, and in the situation that load reaches peak value, its crack width can effectively be controlled in 0.1mm, and the average crack spacing while there is limit destruction is roughly between 0.8～2.5mm.Utilize the good characteristic of this material, be applied to the continuous position of bridge floor, greatly increased the rotational deformation ability at the continuous position of bridge floor, reached the object of the continuous position of thorough solution bridge floor problem easy to crack.
Accompanying drawing explanation
Fig. 1 is simply supported girder bridge bridge floor continuous structure schematic diagram described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to manual word.
The utility model provides a kind of simply supported girder bridge bridge floor continuous structure, as shown in Figure 1, comprising:
Beam body 1, two adjacent one end of beam body is provided with the continuous preformed groove 2 of bridge floor, and the continuous preformed groove overall width of bridge floor is 1680mm, and wherein, two beam body spacing are 80mm;
Bridge floor continuous structure layer 3 and reinforced concrete pavement layer 4, it is all mated formation at adjacent two beam body end faces, described bridge floor continuous structure layer is mated formation at the continuous preformed groove end face of described bridge floor and is extended to both sides, described reinforced concrete pavement layer is mated formation in bridge floor continuous structure layer both sides, the continuous preformed groove of the bonding surface 5 described bridge floor of the distance edge 300～800mm of described bridge floor continuous structure layer and reinforced concrete pavement layer;
