Summary of the invention
The purpose of this utility model is to provide a kind of separate assembling coke oven base structure, overcomes the deficiencies in the prior art, adopts separate assembling foundation structure to reduce thermal stress, reaches and both guarantees security, saves again the purpose of construction investment.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of separate assembling coke oven base structure, this foundation structure is combined by N group structural unit, and this N group structural unit is divided into again 1 end construction unit and (N-2) individual central structure unit and 1 tail structure unit; Last row's Vierendeel girder of described end construction unit is provided with breach step one, and the corresponding overlap joint in the cantilever plate end of described breach step one and the central structure unit be attached thereto is connected; Leaving certain gaps uncovered by the economic plan step two on last row's Vierendeel girder of described central structure unit, the corresponding overlap joint in the cantilever plate end of breach step two and adjacent with it next central structure unit is connected, each central structure unit connects successively backward, until be connected with the cantilever plate end overlap joint of tail structure unit, form a complete coke oven base.
The adjacent junction of the top board on described structural unit and side bar is equipped with Temperature Joint, and described Temperature Joint is provided with some wrong stubble seamings.
The misfit seam that laterally leaves 2 ~ 5mm on described wrong stubble seaming, vertically leave the temperature compensation of 20 ~ 30mm and stitch.
On two formation faces of described misfit seam, sliding steel plate is set respectively, is filled with graphite linings between sliding steel plate.
Compared with prior art, the beneficial effects of the utility model are:
1) adopt the Split assembled thinking, effectively reduced the thermal stress effect, saved material of construction and construction investment, especially in the Application Areas of ultra-large volume coke oven, solved the problem that the coke oven base roof plate overlength is brought.
2) in the Split assembled method, frame column can all adopt the scheme of being rigidly connected, and has avoided overall plan need to consider the complicated requirement of end hinged region and rigidity transition zone, makes design and construction simplify unified.
3) encorbelment mode more reasonable stress and economy of the overlapping mode of plate ratio, the structural system of Split assembled is more novel, stressed more clear and definite, especially is applicable to meeting the linear deformation requirement of overlength coke oven base, for the technical progress of ultra-large volume coke oven technique, provide wide development space.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
The utility model is a kind of separate assembling coke oven base structure, this foundation structure is combined by N group structural unit, this N group structural unit is divided into again 1 end construction unit (see figure 1) and N-2 central structure unit (see figure 2) and 1 tail structure unit (see figure 3), the lateral arrangement of different structure unit is consistent, all according to Fig. 5 mode, arrange skeleton construction, its skeleton construction is comprised of base plate 1, frame column 2, Vierendeel girder 3 and top board 4, and the difference of different structure unit is only longitudinal end form difference.
See Fig. 4, last row's Vierendeel girder of end construction unit is provided with breach step 1, and the corresponding overlap joint in cantilever plate 9 ends of breach step 1 and the central structure unit be attached thereto is connected; Leaving certain gaps uncovered by the economic plan step 2 10 on last row's Vierendeel girder of central structure unit, the corresponding overlap joint in cantilever plate 9 ends of breach step 2 10 and the next central structure unit be attached thereto is connected, each central structure unit connects successively backward, until be connected with the cantilever plate 11 end overlap joints of tail structure unit, form a complete coke oven base.
See Fig. 6, the top board 4 on each structural unit and the adjacent junction of side bar 6 are equipped with Temperature Joint, and for improving connection reliability, Temperature Joint is not form of straight lines, are provided with some wrong stubble seamings on Temperature Joint.The Vierendeel girder at corresponding wrong stubble seaming place is provided with local support 5.
See Fig. 7, on the wrong stubble seaming on top board, laterally leave 2 ~ 5mm(h1) the misfit seam, vertically leave 20 ~ 30mm(h2) the temperature compensation seam, temperature deformation is longitudinally allowed in like this can operative constraint lateral stressed and distortion simultaneously.
