Embodiment Construction

[0028] The present invention is further explained below:

[0029] See Figure 1-5 ,

[0030] The invention discloses a resettable sliding friction shock isolation support, which includes an upper seat plate 1, a lower seat plate 2, a steel spring 3, an I-steel baffle 4, a slider 5, a limit plate 6 and a limit block 7 , The upper seat plate 1 is an inverted "concave"-shaped structure composed of a beam 13 and support beams 14 on both sides, and the lower surface of the top beam 13 forms a concave curved surface 15;

[0031] The lower seat plate 2 has a square structure, and its upper surface is provided with first, second, and third partitions 21, 22, 23 at equal intervals, adjacent to the first, second, and third partitions 21, 22 , There is a limit block 7 connected to it between the two sides of the inner wall of 23, the first, second and third partitions 21, 22, 23, the limit block 7 and the lower seat plate 2 Two grooves 24 are enclosed on the upper surface of the second parti...

Abstract

The invention relates to the technical field of bridge earthquake resistance, in particular to a resettable sliding friction shock insulation and absorption support. The support comprises an upper support plate, a lower support plate, steel springs, I-shaped steel baffles, sliding blocks, limiting plates and limiting blocks. The lower surface of the upper seat plate is a curved surface to be matched with relative sliding of the sliding blocks; when an earthquake occurs, the sliding blocks can slide relatively in the two grooves of the lower base plate, the natural vibration period of the structure is prolonged through sliding friction, and earthquake energy is dissipated. The steel springs are arranged in the middles of the two side walls of the second partition plate of the lower supportplate and connected with the sliding blocks, and after an earthquake is finished, the sliding blocks can reset through the restoring force of the springs. The limiting plates are arranged on the uppersupport plate, and the limiting blocks are arranged on the lower support plate and used for limiting the displacement of the sliding blocks; the I-shaped steel baffles are connected with the upper and lower support plates through bolts to prevent the support from losing efficacy due to separation of the sliding blocks and the upper support plate under the vertical earthquake action.

Description

Technical field [0001] The invention relates to the technical field of bridge seismic resistance, in particular to a resettable sliding friction shock-absorbing support. Background technique [0002] In recent years, with the rapid development of my country’s economic construction, it has led to the rapid development of civil engineering such as railway engineering, highway engineering, and municipal engineering. These projects are inseparable from the construction of bridges. Therefore, bridges are both in number and in The span has been greatly improved. But problems followed. After experiencing major earthquakes such as the Tangshan earthquake in 1976 and the Wenchuan earthquake in Sichuan in 2008, we found that the bridge was seriously damaged. After an earthquake, the damage of the bridge will not only cause the loss of life and property, but also weaken the emergency response ability (affecting the conduct of earthquake relief work, etc.). In view of this, reasonable earthq...
