Description

Technical Field

[0002] In many areas, bridges are the key to smooth traffic. When an earthquake disaster strikes, the destruction of bridges in the earthquake-stricken area means the interruption of lifelines.

[0003] The existing method to improve the seismic performance of bridges usually involves adding cables to the bridge supports to connect the upper and lower support plates of the supports. In this way, when an earthquake or other external force causes the supports to be subjected to forces exceeding the shear displacement limit or horizontal displacement limit of the supports, even if the supports are destroyed, the upper and lower support plates can still be effectively connected, thereby limiting the continued displacement of the beam body and preventing the bridge superstructure from detaching, resulting in the serious consequence of beam falling.

[0004] However, the existing anti-falling beam supports still have the following problems: although the existing bridge supports can rely on cables to prevent beams from falling off, they are unable to buffer and consume the vibrations they are subjected to, which can easily lead to wear between the beam body and other components under the action of vibration. At the same time, the cables will also be damaged and broken due to repeated pulling, that is, the anti-falling beam effect is not good enough. Utility Model Content

[0005] The purpose of the utility model is to provide a Z-shaped steel damping anti-beam falling support to solve the technical problems in the prior art that bridge supports are not convenient for buffering and consuming the vibrations received and the anti-beam falling effect is not good enough.

[0010] As a further solution of the present invention: a limiting block is provided at the bottom of one end of the Z-shaped damping steel plate close to the limiting bolt, and the limiting block fits with the bolt head of the limiting bolt.

[0011] As a further solution of the present invention: a connecting screw passes through the limit block, and the top of the connecting screw is threadedly connected to the bottom surface of the Z-shaped damping steel plate.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1-6As shown, a Z-shaped steel damping anti-fall beam support includes an embedded steel plate 1 and a lower seat plate 7. The embedded steel plate 1 is fixedly installed at the bottom of the bridge by bolts, and the lower seat plate 7 is fixedly installed on the supporting pier body by bolt anchors. The upper seat plate assembly 2 is fixedly connected to the lower part of the embedded steel plate 1, and an intermediate plate 5 is provided above the lower seat plate 7. A lower plane slide groove is provided at the bottom of the intermediate plate 5, and a lower plane slide plate 6 fixedly connected to the lower seat plate 7 is slidably fitted in the lower plane slide groove. A fixing bolt 16 is also connected between the lower seat plate 7 and the intermediate plate 5. When the bridge is affected by seismic loads and the horizontal force borne by the support is greater than the design value, it just exceeds the lateral bearing limit of the fixing bolt 16. In this way, the fixing bolt 16 between the intermediate plate 5 and the lower seat plate 7 is sheared laterally, releasing the seismic load, and relative movement occurs between the bridge and the supporting pier body.

[0029] A movable assembly is provided between the upper seat plate assembly 2 and the middle plate 5. The movable assembly includes an upper plane slide 3 and a spherical crown lining plate 4. The upper plane slide 3 is connected to the bottom of the upper seat plate assembly 2. The upper end surface of the spherical crown lining plate 4 is provided with an upper plane slide groove that is slidably connected to the upper plane slide 3. The bottom of the spherical crown lining plate 4 is connected to a spherical slide 8. The upper end surface of the middle plate 5 is provided with a spherical slide groove that cooperates with the spherical slide 8. When the entire device is subjected to vibration, the bridge can rely on the spherical slide 8 and the upper plane slide 3 to move in the corresponding direction.

[0030] Both sides of the upper seat plate assembly 2 are connected to guide members 9 that slide with the middle plate 5. The guide members 9 facilitate guiding the relative movement between the middle plate 5 and the upper seat plate assembly 2 in corresponding directions.

[0031] A Z-shaped damping steel plate 10 is provided between the embedded steel plate 1 and the lower seat plate 7, and the Z-shaped damping steel plate 10 can undergo elastic deformation; there are two Z-shaped damping steel plates 10, and they are symmetrically distributed between the embedded steel plate 1 and the lower seat plate 7, and a positioning bolt 13 is provided between one end of the Z-shaped damping steel plate 10 and the lower seat plate 7, and the positioning bolt 13 passes through the Z-shaped damping steel plate 10 and is fixedly connected to the lower seat plate 7, and the upper end of the positioning bolt 13 is a bolt head, and is pressed on the Z-shaped damping steel plate 10, and the other end of the Z-shaped damping steel plate 10 is provided with a waist hole 15, and a limiting bolt 14 is passed through the waist hole 15, and the limiting bolt 14 is fixedly connected to the embedded steel plate 1, limiting The diameter of the positioning bolt 14 is smaller than the width of the waist hole 15, so that there is a certain amount of space for movement between the Z-shaped damping steel plate 10 and the positioning bolt 14; a limiting block 11 is provided at the bottom of one end of the Z-shaped damping steel plate 10 near the limiting bolt 14, and the limiting block 11 fits in with the bolt head of the limiting bolt 14. The limiting block 11 is used to prevent the limiting bolt 14 from accidentally rotating and loosening, and falling from the position where the waist hole 15 is located; a connecting screw 17 is passed through the limiting block 11, and the top of the connecting screw 17 is threadedly connected to the bottom surface of the Z-shaped damping steel plate 10, and a cutting groove 12 is provided at the end of the connecting screw 17 near the Z-shaped damping steel plate 10;

[0032] When relative movement occurs between the bridge and the supporting pier, the Z-shaped damping steel plate 10 is elastically deformed by the extrusion of the bridge, consuming energy and playing a role in preventing the beam from falling off. At the same time, since the limiting bolt 14 passes through the waist hole 15 at one end of the Z-shaped damping steel plate 10, it can prevent the Z-shaped damping steel plate 10 from separating from the bottom of the embedded steel plate 1, causing the bridge to lose support. Moreover, the diameter of the limiting bolt 14 is smaller than the width of the waist hole 15, so the Z-shaped damping steel plate 10 can be around the positioning bolt 13 at the other end under the action of vibration. Rotational micro-motion occurs, which avoids torsional deformation and damage, has good fatigue resistance, realizes deformation energy consumption in all directions and anti-beam falling function, and when the Z-type damping steel plate 10 deflects, if the deflection direction is the direction in which the limit block 11 conflicts with the limit bolt 14, then the connecting screw 17 connecting the limit block 11 and the Z-type damping steel plate 10 can be disconnected due to the presence of the cutting groove 12, because the connecting screw 17 at the position where the cutting groove 12 is located has a small diameter and is a weak position, thereby avoiding affecting the movement of the Z-type damping steel plate 10.

[0033] The working principle of the present invention is as follows: when the bridge is affected by earthquake loads and the horizontal force borne by the support is greater than the design value, it just exceeds the lateral bearing limit of the fixing bolts 16, so that the fixing bolts 16 between the middle plate 5 and the lower seat plate 7 are sheared horizontally, releasing the earthquake load. Due to the presence of the lower plane slide 6, the upper plane slide 3 and the spherical slide 8 and other components, relative movement occurs between the bridge and the supporting pier, which facilitates the extrusion of the Z-shaped damping steel plate 10 to cause it to elastically deform and consume vibration energy. At the same time, the Z-shaped damping steel plate 10 is usually kept closed by the limit bolt 14, and the waist hole 15 at one end of the Z-shaped damping steel plate 10 can prevent the Z-shaped damping steel plate 10 from being separated from the bottom of the embedded steel plate 1, thereby preventing the bridge from being separated from the bottom of the embedded steel plate 1. The function of preventing the beam from falling off is realized, and the diameter of the limit bolt 14 is smaller than the width of the waist hole 15. Therefore, the Z-shaped damping steel plate 10 can rotate slightly around the positioning bolt 13 at the other end under the action of vibration, thereby preventing the Z-shaped damping steel plate 10 from being damaged by distortion and deformation, and having good fatigue resistance, realizing the functions of deformation energy dissipation and anti-beam falling in all directions. Moreover, when the Z-shaped damping steel plate 10 deflects, if the deflection direction is the direction in which the limit block 11 conflicts with the limit bolt 14, the connecting screw 17 connecting the limit block 11 and the Z-shaped damping steel plate 10 can be disconnected due to the presence of the cutting groove 12. Because the connecting screw 17 at the position where the cutting groove 12 is located has a small diameter and is a weak position, thereby avoiding affecting the movement of the Z-shaped damping steel plate 10.

[0034] Example 2

[0035] Different from the first embodiment, a flat slide is slidably provided between the upper seat plate assembly 2 and the embedded steel plate 1, and bolts are connected between the upper seat plate assembly 2 and the embedded steel plate 1, and the middle plate 5 and the lower seat plate 7 are an integrated structure; when the seismic load acts, the bolts between the upper seat plate assembly 2 and the embedded steel plate 1 are sheared, and sliding friction energy is consumed between them, and the Z-shaped damping steel plate 10 plays the role of shock absorption and anti-beam falling.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
