Embodiment 1

[0037] like figure 1As shown, the bridge quick replacement support of this embodiment includes an upper guide plate 1, a lower guide plate 2, a support body 3, a fixing member 4, a limiting member 5, an upper support plate 6, and a lower support plate 7. The upper support plate 6 and the lower support plate 7 are horizontally provided with mounting holes for fixing parts. The mounting holes for fixing parts in this embodiment adopt U-shaped holes, and the fixing parts 4 are anchored by pre-embedded bridge decks and bridge piers. One end of the anchor bolt of the bridge deck is buried in the concrete of the bridge deck, and the other end is provided with a first limit hole or opening along the horizontal direction. The end of the anchor bolt provided with the first limit hole or opening passes through the upper guide plate 1 Then pass through the U-shaped hole vertically; the position-limiting member described in this embodiment adopts positioning pins, and the upper support pl...

Embodiment 2

[0042] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the mounting holes of the fixing member are provided on the upper guide plate 1 and the lower guide plate 2, and the fixing member 4 adopts an independent positioning block.

[0043] In the same way as in Embodiment 1, when a new support needs to be replaced, it is only necessary to take out the limiter 5 in the horizontal direction, and then take out the fixing member 4 in the horizontal direction, and the original support body 3 can be dragged out in the horizontal direction; install a new For the support, after pushing the new support body 3 in the horizontal direction, put the fixing part 4 in the horizontal direction, and then insert the limiting part 5 in the horizontal direction to fix it. During the entire replacement process, the fixing part 4 and the limiting part 5 do not need to move vertically, so the jacking distance only needs to satisfy a slight gap between the suppo...

Embodiment 3

[0044] Embodiment 3: as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the fixing member 4 adopts an independent stopper, and the limiting member 5 adopts a limiting bolt.

[0045] In the same way as in Embodiment 1, when a new support needs to be replaced, it is only necessary to take out the limiter 5 in the horizontal direction, and then take out the fixing member 4 in the horizontal direction, and the original support body 3 can be dragged out in the horizontal direction; install a new For the support, after pushing the new support body 3 in the horizontal direction, put the fixing part 4 in the horizontal direction, and then insert the limiting part 5 in the horizontal direction to fix it. During the entire replacement process, the fixing part 4 and the limiting part 5 do not need to move vertically, so the jacking distance only needs to satisfy a slight gap between the support, the bridge deck, and the bridge pier, and avoid close cont...

Abstract

The invention discloses a rapid bridge replacement support base and a rapid replacement method for a bridge support base. The rapid bridge replacement support base comprises an upper guide plate, a support base body, a lower guide plate and an anchoring device, wherein the anchoring device comprises a fixing part and a limiting part; the limiting part penetrates through the fixing part in a horizontal direction to connect and fix the upper guide plate and / or the lower guide plate with the support base body. According to the scheme of the invention, a limiting structure is arranged in a horizontal direction instead of a vertical direction; when the support base is replaced, the jacking distance is only the own thickness distance of the limiting part; compared with the prior art with a length distance to be jacked, the jacking distance of the support base is remarkably reduced, construction can be carried out more conveniently and more easily, and meanwhile, the influence or damage to bridge structures can be remarkably reduced.

Description

technical field [0001] The invention relates to the fields of bridges and buildings, in particular to a quick replacement bearing for a bridge and a quick replacement method for the bridge bearing. Background technique [0002] The bridge support is a key structural component used to connect the beam body and the pier in bridge construction. Its function is to support the structure and adapt to the structure due to thermal expansion and contraction, load, vibration, etc. The movement of the beam body can transfer the load of the girder body to the pier safely, so that the actual stress of the bridge is consistent with the theoretical diagram of the calculation. However, as the connecting body of the bridge, the support bears the load transmitted by the beam body for a long time, which can easily cause accidents such as cracking and local concrete damage. At the same time, the occurrence of catastrophic accidents such as earthquakes will also cause damage to the support. For...
