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
The present invention relates to a kind of bridge engineering protector, particularly relate to a kind of multi-direction fall the anti-locking apparatus of beam.
Background technology
As can be seen from all previous strong ruinous earthquake disaster, the phenomenon that bridge superstructure self damages because of direct earthquake motive force benefit is extremely rare, but the beam that falls caused because of bearing length deficiency, supporting connecting piece inefficacy etc., the phenomenon such as movement, distortion, crack of girder often have generation, and its decline beam phenomenon is very serious.Bridge, as the multi-purpose project in traffic lines, once the beam that falls destroys, will make whole transportation network paralyse, and serious obstruction is rescued and rebuilding in disaster-hit areas.China is the multiple country of an earthquake, but the research to bridge girder falling, a certain distance is also had compared with other countries.
Because the defect that above-mentioned existing bridge girder falling exists, the design people, actively in addition research and innovation, to found a kind of new structure multi-direction fall the anti-locking apparatus of beam, make it have more practicality.
Summary of the invention
Main purpose of the present invention is, overcomes the defect that existing bridge girder falling exists, and provide a kind of novel multi-direction fall the anti-locking apparatus of beam, invariably earthquake centre falls the generation of beam accident, thus is more suitable for practicality, and has the value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to the present invention propose multi-direction fall the anti-locking apparatus of beam, include prestress wire and anchoring nut, described prestress wire is at least one, and connect and be arranged between parados and beam body, the two ends of described prestress wire are fixed on described parados and Liang Tishang respectively by anchoring nut; What described prestress wire tilted is connected to parados and Liang Tishang.
Further, aforesaid multi-direction fall the anti-locking apparatus of beam, described prestress wire is at least two, and two prestress wires are all connected between parados and beam body, and two prestress wires cross in centre position.
Further, aforesaid multi-direction fall the anti-locking apparatus of beam, described prestress wire and beam body junction are provided with yielding rubber.
Further, aforesaid multi-direction fall the anti-locking apparatus of beam, the arranged outside of described yielding rubber has spring.
Further, aforesaid multi-direction fall the anti-locking apparatus of beam, the link position place of described prestress wire and parados, is also provided with firm pad between anchoring nut and parados.
By technique scheme, of the present invention multi-direction fall the anti-locking apparatus of beam at least there is following advantages:
Of the present invention multi-direction fall the anti-locking apparatus of beam, overall structure structure is fairly simple, easy construction, existing reliable longitudinal girder falling performance, has again good horizontal girder falling effect, perfect in shape and function, simple for structure, invariably earthquake centre falls the generation of beam accident, reaches the object of providing fortification against earthquakes, and improves the structure security performance of structure.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation

Fig. 2 be the present invention multi-direction fall the front view of the anti-locking apparatus of beam;
Connotation is marked: 1. prestress wire, 2. firm pad, 3. anchoring nut, 4. yielding rubber, 5. spring, 6. parados and 7. beam bodies in figure.
Detailed description of the invention
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment of the present invention is described in detail as follows.
As depicted in figs. 1 and 2 the present invention multi-direction fall the structural representation of the anti-locking apparatus of beam, include prestress wire 1, just pad 2, anchoring nut 3, yielding rubber 4 and spring 5 respectively.
Prestress wire 1 is two, and connect and be arranged between parados 6 and beam body 7, the two ends of prestress wire 1 are fixed on parados 6 and beam body 7 respectively by anchoring nut 3, and two prestress wires 1 cross in centre position.Prestress wire 1 and beam body 7 junction are provided with yielding rubber 4, and the arranged outside of yielding rubber 4 has spring 5, and yielding rubber 4 and spring 5 can play the effect of double buffering prestress wire 1 tensile stress.Prestress wire 1 and the link position place of parados 6, be also provided with firm pad 2 between anchoring nut 3 and parados 6.
When beam body 7 is along vertical bridge to when being subjected to displacement, prestress wire 1 is along the axial generation effect of bridge, and restraint beam body 7 is subjected to displacement further; When beam body 7 is subjected to displacement along direction across bridge, the prestress wire 1 of arranged crosswise can the lateral displacement of restraint beam body 7, reaches the standard of dual girder falling.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
