Description
Technical field
The utility model relates to a kind of supporting construction depositing steel box-girder.
Background technology
After the dismounting of urban viaduct steel box-girder, generally need to deposit on certain place, so that the later stage also builds.Because the steel box-girder after removing is heavier, and need to deposit the long period, and common place cannot meet storage condition, easily causes beam body deformability, therefore protection is deposited is very important work.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of supporting construction depositing steel box-girder, to guarantee that beam body is indeformable in long storage time process.
To achieve these goals, the technical solution of the utility model is: a kind of supporting construction depositing steel box-girder, comprise place, described place lower floor is graded broken stone layer, upper strata, described place is concrete layer, described place is provided with the concrete prefabricated pier of multiple well-distributed, described concrete prefabricated pier is all placed with the lower steel buttress for supporting lower floor's steel box-girder, described lower steel buttress is positioned over web and the dividing plate crossover location of lower floor's steel box-girder, concrete pavement layer on the upside of described lower floor steel box-girder is placed with the upper steel buttress for supporting upper strata steel box-girder, described upper steel buttress is positioned over web and the dividing plate crossover location of upper strata steel box-girder.
Further, described upper steel buttress and lower steel buttress are all placed with the chock adjusting steel box-girder height.
Further, described graded broken stone layer is formed by the graded broken stone compacting of two-layer 300mm altogether, its degree of compaction >=95%.
Further, described concrete layer adopts C25 concreting to form, and its thickness is 150mm, and surface is super flat.
Further, described concrete surface is provided with the weathering of the gradient 0.5%, and described concrete layer is provided with weep drain in lower one end of weathering.
Further, described concrete prefabricated pier adopts the reinforced concrete knoll of C20 concreting.
Further, described upper steel buttress and lower steel buttress all adopt L100*7 angle steel to be welded.
Compared with prior art, the utility model has following beneficial effect: beam section takes bilayer to deposit, and when depositing, interim point supporting is at the infall of vertical web and cross wall, basis is firm, not uneven sedimentation, makes supporting-point uniform force, ensure that beam body is indeformable.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Fig. 1 ~ 7, a kind of supporting construction depositing steel box-girder, comprise place 1, described place 1 lower floor is graded broken stone layer 11, upper strata, described place 1 is concrete layer 12, described place 1 is provided with four concrete prefabricated piers 2 of well-distributed, described concrete prefabricated pier 2 is all placed with the lower steel buttress 3 for supporting lower floor's steel box-girder 4, described lower steel buttress 3 is positioned over web and the dividing plate crossover location of lower floor's steel box-girder 4, concrete pavement layer 41 on the upside of described lower floor steel box-girder 4 is placed with the upper steel buttress 5 for supporting upper strata steel box-girder 6, described upper steel buttress 5 is positioned over web and the dividing plate crossover location of upper strata steel box-girder 6.
In the present embodiment, in order to make place 1 firm, described graded broken stone layer 11 is formed by the graded broken stone compacting of two-layer 300mm altogether, its degree of compaction >=95%; Described concrete layer 12 adopts C25 concreting to form, and compressive strength is 25MPa, and its thickness is 150mm, and surface is super flat.
In the present embodiment, in order to yard drain is unobstructed, described concrete layer 12 surface is provided with the weathering 13 of the gradient 0.5%, and described concrete layer 12 is provided with weep drain 14 in lower one end of weathering 13, to avoid steel box-girder storage space internal water accumulation, cause setting of ground.
In the present embodiment, in order to prevent steel buttress by ponding corrosion failure, described concrete prefabricated pier 2 adopts the reinforced concrete knoll of C20 concreting, include reinforced mesh 21 in described concrete prefabricated pier 2, described concrete prefabricated pier 2 both sides are prefabricated with two hangers 22 to facilitate layout inside.
