Embodiment Construction

[0016] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose of the invention, the specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0017] like figure 1 and figure 2 The schematic diagram of the structure of the multi-directional beam fall prevention device of the present invention is shown, which respectively includes a prestressed steel strand 1 , a rigid washer 2 , an anchor nut 3 , a buffer rubber 4 and a spring 5 .

[0018] There are two prestressed steel strands 1, which are connected between the back wall 6 and the beam body 7, and the two ends of the prestressed steel strand 1 are respectively fixed on the back wall 6 and the beam body 7 by anchor nuts 3. The prestressed steel strands 1 meet at the middle position. The connection between the prestressed steel strand 1 and the beam body 7...

Abstract

The invention discloses a multi-directional anti-drop-beam device. The multi-directional anti-drop-beam device comprises at least one prestressed steel strand and anchoring nuts, wherein the at least one prestressed steel strand is connected between a back wall and a beam body; the two ends of the prestressed steel strand are fixed on the back wall and the beam body through the anchoring nuts; the prestressed steel strand is connected to the back wall and the beam body in an inclined manner. The multi-directional anti-drop-beam device disclosed by the invention is relatively simple in overall structure and convenient to construct, and has reliable longitudinal anti-drop-beam performance and a good transverse anti-drop-beam effect; besides, functions are complete, the structure is concise, a beam dropping accident in an earthquake is avoided, the purpose of earthquake fortification is achieved, and the construction safety performance of the structure is improved.

Description

technical field [0001] The invention relates to a bridge engineering protection device, in particular to a multi-directional beam fall preventing device. Background technique [0002] It can be seen from the previous strong destructive earthquake disasters that the destruction of the bridge superstructure itself due to direct seismic dynamic benefits is extremely rare, but the falling beams, main girder movement, Distortion, cracks and other phenomena often occur, among which the phenomenon of falling beams is extremely serious. As a pivotal project on the transportation line, the bridge will paralyze the entire transportation network once the beam falls and is damaged, seriously hindering rescue and post-disaster reconstruction work. Our country is a country with frequent earthquakes, but compared with other countries, there is still a certain gap in the research on bridge fall prevention beams. [0003] In view of the defects of the above-mentioned existing bridge anti-f...
