Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Multilayer bridge overhanging isolation structure as shown in Figure 1, comprise building concentration 1 and be arranged at left redundant monomer 2 and the right redundant monomer 3 of building concentration 1 left and right sides respectively, wherein the bottom girder 11 of building concentration 1 is fixedly installed on building concentration stub 13, the left bottom girder 21 of left redundant monomer 2 is fixedly installed on left redundant monomer stub 23, the right bottom girder 31 of right redundant monomer 3 is fixedly installed on right redundant monomer stub 33, described bottom girder 11 and be provided with deformation joint 4 between left bottom girder 21 and right bottom girder 31, the below being positioned at the deformation joint 4 at bottom girder about 11 two ends is provided with shock insulation braced structures 5, described shock insulation braced structures 5 supports bottom girder 11 by shock isolating pedestal 51, left bottom girder 21 and right bottom girder 31.
When reality is built, first need building concentration stub 13, left redundant monomer stub 23, right redundant monomer stub 33 to be fixedly installed on selected ground 6, the ground 6 of indication refers to the bottom part in river here.In conjunction with practical experience, the spacing between stub should be best within 30 meters.When building concentration 1, left redundant monomer 2 and right redundant monomer 3 are arranged, need in the bottom girder termination 111 at two ends and leave deformation joint 4 respectively between left bottom girder seam end 211 and right bottom girder seam end 311, deformation joint 4 not only ensures that shelter bridge can bear the impacts such as earthquake, and what also allow bottom girder 11 can be comparatively complete provides sturdy ground for the building above bottom girder 11.In order to make up because deformation joint 4 exists, so stitch the bottom girder termination of 4 both sides in order to better supporting deformation, select to be provided with shock insulation braced structures 5 in the below of deformation joint 4, described shock insulation braced structures 5 supports bottom girder 11, left bottom girder 21 and right bottom girder 31 by shock isolating pedestal 51, bottom girder termination 111, left bottom girder seam end 211, right bottom girder seam end 311 so both can have been allowed effectively to be supported, described shock isolating pedestal 51 can also bear corner distortion, longitudinal free displacement, lateral displacement etc. from the distortion of shelter bridge, considerably increases the stability of structure.Because left bottom girder fixed end 212 and right bottom girder fixed end 312 are fixed on land, two sides, river, therefore the actual span of shelter bridge is the distance between left bottom girder fixed end 212 and right bottom girder fixed end 312.
Because the present invention is mainly applied on shelter bridge, therefore view loft 12 can be built on the bottom girder 11 of building concentration 1, dining room 14 can also be built in view loft 12 basis, Landscape Architecture 15 modelled after an antique can also be built above dining room 14, and build lobby 16 on Landscape Architecture 15 modelled after an antique.Owing to having set up deformation joint 4, just substantially reduce geology and changed to the destructive power of building above building concentration 1, also due to without traditional shrinkage joint, the building on bottom girder 11 can have been allowed more firm.Naturally, left bottom girder 21 also can be built left redundant monomer view loft 22, right bottom girder 31 also can be built right redundant monomer view loft 32.
