Detailed description of the invention
Refer to Fig. 1-7, the utility model discloses a kind of shaped steel shear key connecting structure of building deformation joint.As shown in the figure: it arranges transverse horizontal hole 2 on the girder 1 of the opposite position of deformation joint 6 both sides, and the secondary beam 5 of opposite position in deformation joint both sides being arranged the shaped steel shear key 6 corresponding to transverse horizontal hole 2, this shaped steel shear key 6 passes in transverse horizontal hole 2.
As preferred structure, this transverse horizontal hole 2 liner rectangle steel sleeve pipe 3.This rectangle steel sleeve pipe 3 inner bottom part is provided with and supports shaped steel shear key 6 and the polyfluortetraethylene plate reducing force of sliding friction.
As preferred structure, this transverse horizontal hole 2 and shaped steel shear key 6 arrange multipair.The shaped steel shear key group number of transverse horizontal hole and correspondence, needs to determine with floor width.
As alternate configurations, this shaped steel shear key 6 is H profile steel, square tube or T-steel of putting upside down.
During manufacture, transverse horizontal hole 2 is formed by pre-buried rectangle steel sleeve pipe 3 after-pouring concrete, rectangle steel sleeve pipe 3 width is slightly less than girder 1 stirrup spacing, slightly larger than shaped steel shear key 6 width, rectangle steel sleeve pipe 3 highly needs depending on differential settlement and secondary beam bending rigidity determines the relation with shaped steel shear key depth of section to settlement-sensitive degree.
This shaped steel shear key 6 is whole to be watered in secondary beam 5.Shaped steel shear key 6 length is made up of embedded section and overhanging section, embedded section is positioned at secondary beam 5 stirrup and is welded with shear stud, and overhanging segment length minimum support length that is wide by deformation joint, transverse horizontal hole 2 on girder 1, calculating both sides floor relative shift three part sum are determined.Shaped steel shear key 6 cross dimensions, main basis time beam end shearing size is determined.
In addition, during construction, between deformation joint, be encased inside polystyrene board, both sides concrete can be built easily simultaneously.
As shown in Figure 7: establish transverse horizontal hole 2 due on the beam that the utility model has post to support on the floor of both sides, shaped steel shear key 6 is established in being stayed by support time beam end of opposite side, and shaped steel shear key 6 slides through transverse horizontal hole 2.Therefore, make deformation joint both sides flooring have relative rotational motion capability (relatively rotating direction 11 in horizontal plane), vertical relative displacement ability (vertical relative displacement direction 10) in relative sliding ability (glide direction 9 perpendicular to seam), horizontal plane, limit the horizontal changing of the relative positions ability (confined along the horizontal offset direction 12 of seam) perpendicular to seam direction simultaneously.
Here description of the present utility model and application is illustrative, not wants by scope restriction of the present utility model in the above-described embodiments.Distortion and the change of embodiment disclosed are here possible, are known for the replacement of embodiment those those of ordinary skill in the art and the various parts of equivalence.Those skilled in the art are noted that when not departing from spirit of the present utility model or substantive characteristics, the utility model can in other forms, structure, layout, ratio, and to realize with other assembly, material and parts.When not departing from the utility model scope and spirit, can other distortion be carried out here to disclosed embodiment and change.
