Embodiment 1

[0030] Such as Figure 1-6 As shown, an assembled bridge support includes:

[0031] Column 1, the column 1 is assembled and fixed by the bent frame and the longitudinal beam through the butt joint fastener, and the lower end of the column 1 is provided with a concrete pile 11;

[0032] Load-bearing beam 2, the load-bearing beam 2 is erected on the upper end of the column 1, and the load-bearing beam 2 is I-beam;

[0033] The anti-collision mechanism 3, the anti-collision mechanism 3 is installed on the surface of the column 1, and the cushion layer 4 is provided between the anti-collision mechanism 3 and the column 1, which can form a good buffering effect on the impact of the vehicle;

[0034] The cushion layer 4 includes two mounting plates 41 which are respectively fixedly connected with the column 1 and the anti-collision mechanism 3 , and a plurality of air pads 42 are equidistantly arranged between the two mounting plates 41 .

[0035] Further, the anti-collision mecha...

Abstract

The invention belongs to the technical field of bridge construction, and particularly relates to a fabricated bridge support. The support comprises: a stand column, wherein the stand column is formed by assembling and fixing bent frames and longitudinal beams through butt joint fasteners, and a concrete pile column is arranged at the lower end of the stand column; a bearing beam which is erected at the upper end of the stand column, wherein the bearing beam is I-shaped steel; and an anti-collision mechanism which is installed on the surface of the stand column, wherein a buffering cushion layer is arranged between the anti-collision mechanism and the stand column. The buffering cushion layer comprises two mounting plates, the two mounting plates are fixedly connected with the stand column and the anti-collision mechanism correspondingly, and a plurality of air cushions are arranged between the two mounting plates at equal intervals. A good buffering effect can be achieved on vehicle collision, rigid collision between the stand column and a vehicle is avoided, deformation of the stand column due to collision is prevented, and the possibility of dangerous accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an assembled bridge support. Background technique [0002] The rapid development of prefabricated bridge engineering, the expansion of project scale and the complexity of the structural system have brought complexity and safety issues to the construction process. Safety, energy saving and civilized construction of prefabricated bridges are the development trend of the bridge industry. [0003] When the existing prefabricated bridge is constructed on the roadway, the column support must be equipped with a portal support that meets the clearance requirements of the road (pedestrian or vehicle), so as to ensure the smoothness of the existing road during the construction period and the prefabricated bridge on the roadway. Most of the bridge supports are only equipped with warning devices and do not have anti-collision facilities. When a car accident occurs, th...
