Detailed description of the invention
Be present pre-ferred embodiments as Figure 1-3:
What the present invention disclosed is a kind of sliding support be made up of steel beam column, and comprise girder steel 6 and be embedded in dowel 1, the embedded board 2 of civil engineering structure in advance, described embedded board 2 is fixedly welded on dowel 1; Described girder steel 6 is fixedly welded with a plate 5 with embedded board 2 junction, and this junction plate 5 is connected with embedded board 2; The inner side edge of embedded board 2 is fixedly welded with a limiting plate 3, the dual-side of embedded board 2 is fixedly welded with two spacing angle steel 4, described limiting plate 3 can limit the lateral displacement of junction plate 5, and described two spacing angle steel 4 can limit the length travel of junction plate 5.
Further, the thickness of described junction plate 5 is greater than the thickness of limiting plate 3; Described junction plate 5 and embedded board 2 mutually frictional fit are connected, and junction plate 5 can relative to embedded board 2 displacement; Described limiting plate 3 with and junction plate 5 between from and there is enough sliding distances; Described girder steel 6 is provided with stiffener 7 with embedded board 2 connecting end portion.
In the present embodiment, dowel 1 is connected with embedded board 2 plug welding, and dowel 1 and embedded board 2 are embedded on civil engineering structure.Reserved structure in certain the present embodiment is also not limited to dowel and embedded board is embedded on civil engineering structure, and on original structure, reserved steel corbel is suitable for too.
Limiting plate 3 and spacing angle steel 4 are welded on embedded board 2, limit axial displacement and the lateral displacement of girder steel respectively.Limiting plate 3 and spacing angle steel 4 self need meet spacing required strength and stiffness, and the bonding strength of itself and embedded board 2 also needs to meet spacing needs.
Girder steel bottom flange junction plate 5 is welded on end, girder steel 6 bottom flange, is shelved on embedded board 2.Girder steel bottom flange junction plate 5, the frictional force of itself and embedded board 2 is greater than and combines by wind load, temperature action the horizontal force caused, and to ensure that vestibule is static under common using state, ensures the comfortableness of top pedestrian.
Embedded board 2, need ensure there are enough sliding distances between bottom flange junction plate 5 and limiting plate 3, as the first line of defence of vestibule slippage under little shake and middle shake operating mode.Limiting plate 3 just works under earthquake operating mode, as the second defence line of vestibule slippage under severe earthquake action.
