Example Embodiment
[0025] Example 1:
[0026] Such as Figure 1-3 As shown, for a traditional continuous beam bridge, in order to ensure that the bridge main girder 9 can be freely expanded and contracted due to temperature changes during normal use, the bridge main girder 9 is generally rigidly connected to one of the piers, and sliding bearings are set on the other piers. The way of articulation. However, under the action of earthquake or vehicle impact, energy tends to concentrate on the pier rigidly connected to the main girder, causing local stress concentration and damage. The speed-type structural connection locking device containing the shear thickening fluid is installed near the multiple sliding supports 10 of the bridge and connected to the bridge pier 11 and the bridge main girder 9. The connection locking device basically does not restrict the slow motion caused by temperature, shrinkage and creep in the bridge structure, that is, it does not affect the normal use of the structure. ...
Example Embodiment
[0030] Example 2:
[0031] Such as Figure 4 As shown, for some building structures with a relatively large plane size, in order to prevent the structure from cracking or breaking due to changes in climate and temperature, it is often necessary to install vertical expansion joints 12 along the length of the structure. Under the action of an earthquake, the structural parts 13 and 14 on both sides of the expansion joint 12 are likely to collide, causing local damage to the structure, which will lead to structural failure in severe cases. A plurality of speed-type structural connection locking devices containing shear thickening liquid are evenly installed between the expansion joints 12 of the structure, and the two ends of the connection locking device are connected to the structures 13 and 14 on both sides of the expansion joint 12 respectively. The connection locking device does not restrict the normal shrinkage and creep of the structure due to temperature. When the structure...
