Description
Technical field
This utility model relates to the technical field of bridge construction structure, especially a kind of Longspan Bridge expanded joint structure.
Background technology
Expansion joint is the structure that bridge designs to adapt to the change of ambient temperature and load, it is possible to achieve the free deformation of bridge.A kind of bridge expanssion joint disclosed in Chinese utility model patent CN203768806U, can make rubber tube stress on four direction when deforming upon, and extends the life-span of rubber tube.
But, this structure above-mentioned adopts horizontally disposed Y shaped bracket as the transmission of active force and buffer structure, this structure has good cushioning effect for the active force of horizontal direction, but, active force for vertical direction, the Y shaped bracket of this horizontally set just cannot be carried out good buffering, when active force is excessive, it is possible to there will be the situations such as expanded joint structure dislocation.So in sum, existing expanded joint structure there is also very big defect in structure and design, it is impossible to meets the needs that modern society is actual.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, it is provided that a kind of Longspan Bridge expansion joint, simple in construction, telescopic extensions are big, are suitable for the large bridge of bigger length or long span.
This utility model solves its technical problem and be the technical scheme is that a kind of Longspan Bridge expanded joint structure, is mainly made up of spanning, bridge plate, support plate, support column, sliding panel, anchor, oscillating deck and bridge column；Described bridge column is fixedly installed in spanning, one end of described bridge plate is fixedly installed on the upper end of bridge column, the other end of described bridge plate is fixedly connected on anchor, described anchor is also connected with being provided with sliding panel, the opposite side of described anchor is flexibly connected oscillating deck, the lower slide of described anchor is arranged on support plate, and the lower end of described support plate is fixedly installed many support columns, and described support column is fixedly installed in spanning.
Further specifically, in technique scheme, described support plate is arc structure, and the front-end and back-end of described arcuation support plate are both provided with block rubber.There is excess of stroke phenomenon when can effectively prevent sliding panel movable in bridge deformation process in such design.
Further specifically, in technique scheme, described bridge plate upper surface is additionally provided with notch.Such design can reduce the impact that the effect that bridge expands with heat and contract with cold is brought to bridge.
Further specifically, in technique scheme, described oscillating deck upper surface is additionally provided with notch.Such design can reduce the impact that the effect that bridge expands with heat and contract with cold is brought to bridge.
Further specifically, in technique scheme, the afterbody of described sliding panel is additionally provided with briquetting.Such design is so that support plate plays the effect of balance, effectively prevents bridge from the phenomenon of fracture occur.
The beneficial effects of the utility model are: simple in construction, and telescopic extensions is big, are suitable for the large bridge of bigger length or long span, improve the safety in utilization of bridge.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Being numbered in accompanying drawing: 1, spanning, 2, bridge plate, 3, support plate, 4, support column, 5, sliding panel, 6, anchor, 7, oscillating deck, 8, bridge column, 9, block rubber, 10, notch, 11, briquetting.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
This utility model one Longspan Bridge expanded joint structure as shown in Figure 1, is mainly made up of spanning 1, bridge plate 2, support plate 3, support column 4, sliding panel 5, anchor 6, oscillating deck 7 and bridge column 8；Bridge column 8 is fixedly installed in spanning 1, one end of bridge plate 2 is fixedly installed on the upper end of bridge column 8, the other end of bridge plate 2 is fixedly connected on anchor 6, anchor 6 is also connected be provided with sliding panel 5, the opposite side of anchor 6 is flexibly connected oscillating deck 7, the lower slide of anchor 6 is arranged on support plate 3, and the lower end of support plate 3 is fixedly installed many support columns 4, and support column 4 is fixedly installed in spanning 1.
Wherein, support plate 3 is in arc structure, and the front-end and back-end of support plate 3 are both provided with block rubber 9.Bridge plate 2 upper surface is additionally provided with notch 10.Oscillating deck 7 upper surface is additionally provided with notch 10.The afterbody of sliding panel 5 is additionally provided with briquetting 11.
Bridge seam is formed between spanning 1 and spanning 1, when along with the change of weather, there is the phenomenon expanded with heat and contract with cold in bridge itself, sliding panel 5 can carry out certain displacement therewith on support plate 3, now oscillating deck 7 also can move therewith, such connected effect can effectively reduce bridge and expand with heat and contract with cold the destruction to bridge itself, improves the service life of bridge, improves safety in utilization.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
