However, due to the rigid constraints in the direction of the bridge, and because the one-way sliding bearings cannot ablate the displacement difference between the bridge nodes and the one-way sliding bearings, it is easy to cause the corridor bridge to lose its position relative to the The towers are locked, so that the support or bridge structure of the covered bridge is damaged when the two towers are twisted, causing more serious consequences

Embodiment 1
[0070] This embodiment provides an anti-lock one-way sliding shock-absorbing hinge support, which is used for high-altitude corridor bridges in high-rise conjoined buildings, including an upper seat 1, a lower seat 2, a spherical crown plate member 3, an elastic member, a shear Side plate 6 and anti-falling plate 7.
[0071] Specifically, as Figure 3 to Figure 4 As shown, the upper seat 1 includes an upper seat plate 11, a force transmission transition piece 12 located at the center of the lower end surface of the upper seat plate 11, a flat stainless steel plate 13 arranged between the upper seat plate 11 and the force transmission transition piece 12 from top to bottom, and Flat slide plate 14.
[0072] Specifically, as Figure 5 to Figure 7 As shown, the lower seat 2 includes a lower seat plate 21 , and an anti-pull column 22 fixed at the center of the upper end surface of the lower seat plate 21 and having a concave spherical surface 220 on the top surface. Wherein, th...
Embodiment 2
[0080] On the basis of Example 1, as Figure 3 to Figure 13 , Figure 16 to Figure 17 As shown, an L-shaped anti-collision key 9 is arranged on the inner wall of the shear plate 61 along the bridge and above the leaf spring 51, and its short side is installed on the inner wall of the shear plate 61 along the bridge through bolts 8, and the short side of the The top is against the bottom wall of the upper seat plate 11, and the long side of the L-shaped anti-collision key 9 points to the force transmission transition piece 12, and the trapezoidal groove 122 is provided with a wall for fixing the shaft bolt 52 to provide an L-shaped anti-collision key. The guide groove 123 that key 9 stretches into, the upper groove wall 124 of guide groove 123 is longer than the lower groove wall 125, and the upper groove wall 124 is pressed against by the long side of L-shaped anti-collision key 9.
[0081]The L-shaped anti-collision key 9 fixed on the shear plate 61 along the bridge, its lon...
Embodiment 3
[0083] This embodiment provides another anti-lock one-way sliding shock-absorbing hinge support, which includes an upper seat 1 , a lower seat 2 , a spherical cap plate member 3 , an elastic member, a shear side plate 6 and an L-shaped anti-collision key 9 .
[0084] Specifically, such as Figure 5 to Figure 8 , Figure 11 to Figure 12 ,as well as Figure 18 to Figure 19 As shown, the upper seat 1 includes an upper seat plate 11, a force transmission transition piece 12 located at the center of the lower end surface of the upper seat plate 11, a flat stainless steel plate 13 arranged between the upper seat plate 11 and the force transmission transition piece 12 from top to bottom, and Flat slide plate 14. The lower seat 2 includes a lower seat plate 21 , and an anti-pull column 22 fixed at the center of the upper end surface of the lower seat plate 21 and having a concave spherical surface 220 on the top surface. The force transmission transition piece 12 is a cover body, a...

Abstract
The invention provides an anti-locking one-way sliding damping hinged support. The anti-locking one-way sliding damping hinged support comprises an upper seat, a lower seat rotationally buckled by the upper seat, and a spherical crown plate component arranged at the top of the lower seat and pressed by the upper seat, and is characterized by further comprising a shear-resistant side plate connected to the side edge of the upper seat and extending downwards, and an elastic piece with two tail ends connected with the shear-resistant side plate and the upper seat respectively, wherein the elastic piece mainly comprises a plate spring assembly with small rigidity and large allowable deformation and a disc spring assembly with large rigidity and small allowable deformation. According to the anti-locking one-way sliding damping hinged support, through the disc spring assembly arranged in the transverse bridge direction and the plate spring assembly arranged in the longitudinal bridge direction, the two-way rigidity of the support is inconsistent; meanwhile, due to the fact that the disc spring assembly has the characteristics of being large in rigidity and small in allowable displacement amount, strong wind with the large recurrence period suffered by a gallery bridge can be effectively resisted, and compared with the support with rigidity constraint in the transverse bridge direction, the anti-locking one-way sliding damping hinged support can greatly avoid the situation that a bridge body structure is damaged due to the fact that the gallery bridge is locked relative to a tower.
Description
technical field [0001] The invention relates to a shock-isolation and shock-absorbing structure of a fixed building, in particular to an anti-locking one-way sliding shock-absorbing hinge support. Background technique [0002] For the existing support nodes, leaf springs are usually used to achieve buffering for dynamic loads. For example, the comparative document of the announcement number CN204385607U discloses an anti-seismic connection seat, such as Figure 1 to Figure 2 As shown, the anti-seismic connecting seat is buffered by leaf spring 70 in both the direction of the bridge and the direction of the bridge. When an earthquake occurs, the end of the leaf spring 70 receives an excessive instantaneous dynamic load. The end of 70 scrapes against the inner side wall of box body 10 with high frequency, so that the inner side wall of box body 10 is scraped out of the stepped protrusion, and then causes the movement of the end of leaf spring 70 to be hindered by the protrusio...
