Low cost, and construction and later maintenance are also beneficial to, meet low-carbon economy mode.
Existing single-column expansion joint technology status：Chinese patent 201120415376 discloses a kind of double girder expansion joints of single-column
Structure, the structure include Y type columns, are connected to the girder, secondary beam and floor of styletable, the Y types column styletable is equipped with expansion joint, main
Beam is mutually perpendicular to secondary beam, and girder is arranged in parallel in expansion joint both sides, and floor covering girder and secondary beam are arranged on expansion joint both sides.
The secondary beam vertical with double girders and floor disconnect at double girders, and the dilatation of beam slab is converted at double girders between expansion joint
The torsional deflection of double girders, and it is further converted into the flexural deformation of Y type columns upper end bifurcated section.The structure is primarily adapted for use in ground
The single-column of lower ceiling plate sets seam, narrow scope of application, and deformation need to be converted several times, and power transmission is not direct, and the construction of nonstandard Y shape column is also compared
It is more difficult.Chinese patent 201120554620 discloses a kind of single-column horizontal sliding expansion joint, is mainly set in the bilateral of column
Rubber sliding support is put to realize single-column expansion joint, while steel corbel is equipped between sliding support and column, but the structure
Costly, construction is more complicated, also has an impact to facade, narrow scope of application.
