Embodiment Construction

[0020] Below in conjunction with accompanying drawing, structure of the present invention, construction process are further described as follows.

[0021] figure 1 It is a plan view of the anti-overturning support, where the dotted line represents the lower structure covered by the upper beam body 3 . A-A profile such as figure 2 As shown, the anti-overturning support is composed of a steel plate 2 under the support, a fixing bolt 3, a rubber support 4, a screw rod 5, an elastic material tube 6, a nut 7 and a steel plate 8 on the support. The screw rod 5 is welded on the steel plate 2 under the support, surrounded by an elastic material tube 6, which can be a plastic tube or a rubber tube, and the outer diameter of the nut 7 is larger than the diameter of the hole reserved in the upper beam body 9 to ensure that the nut can Together with the screw rod 5, the vertical displacement of the upper beam body 9 is restrained. B-B profile such as image 3 As shown, it shows the c...

Abstract

The invention discloses a bridge anti-overturning support and a construction method for the bridge anti-overturning support, and belongs to the technical field of structural engineering. The anti-overturning support can greatly improve the whole firmness of a bridge floor system and comprises a support lower steel plate, a fixing bolt, a rubber support, a screw rod, an elastic material pipe, a screw cap and a support upper steel plate; the support lower steel plate is fixed to a cover beam through the fixing bolt, and the screw rod is welded to the support lower steel plate and penetrates prefabricated holes in the rubber support and the support upper steel plate; and the periphery of the screw rod is wrapped with the elastic material tube, and the screw rod and the screw cap are mechanically connected through threads. As the anti-overturning support is adopted in a bridge structure, overturning of the bridge floor system under the unbalance loading effect can be effectively prevented, and additional internal force caused by deformation generated by concrete shrinkage and the temperature effect can be avoided; and the bridge anti-overturning support is simple in structure and reasonable in stress, facilitates material taking and has the good technical and economic benefits.

Description

technical field [0001] The invention relates to an anti-overturning support applied to bridge structures, belonging to the technical field of structural engineering. Background technique [0002] As the component connecting the cap beam and the bridge deck system, the bridge bearing plays an important role in the normal use of the bridge structure. The bridge support is set on the cover beam, and undertakes the upper bridge deck system, and adapts to the deformation and displacement of the bridge deck system during the normal use stage of the bridge. [0003] my country's highway bridges, especially urban viaducts, currently use plate-type and pot-type rubber bearings. The bridge deck is placed directly on the support, and the support cannot restrain the vertical displacement of the bridge deck. When a large eccentric load acts, the bridge deck system may have a risk of overturning due to a large torque, such as the overturning caused by the eccentric load of an overloaded v...
