Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a replaceable support system limiting device. Background Technology

[0002] To prevent bridge beams from slipping and falling due to relative displacement caused by temperature, vehicles, and especially earthquakes, and to ensure the normal use of bridges and the safe passage of vehicles, limiting devices are usually used to restrict the relative displacement between bridge beams.

[0003] Currently, the most common type of limiting device consists of protrusions on the upper bridge beam and lower pier. While this type of limiting device can restrict the displacement of the upper bridge, it suffers from poor transparency and aesthetics, and the seismic blocks are welded to the bridge beam, making disassembly difficult. Therefore, a limiting device needs to be designed that, while fulfilling its normal limiting function, also considers overall aesthetics and facilitates routine maintenance and replacement of the bearings. Utility model patent CN 213233112 U, entitled "A Limiting Device Combined with a Bearing System," discloses a bridge limiting device, but its application in bridges has the following shortcomings:

[0004] 1) The baffle is fitted around the support system to limit movement. Making bolt holes in the connecting steel plate and the baffle, and then connecting the support system and the baffle with fasteners, has little impact on enhancing the limiting effect; instead, it increases the construction difficulty and project cost.

[0005] 2) The baffle is welded to the upper surface of the pier, which makes it inconvenient for the daily inspection and replacement of the support. Utility Model Content

[0006] The purpose of this invention is to provide an easily replaceable support system limiting device to solve the above-mentioned problems.

The support assembly includes a bearing, a support steel plate, a connecting steel plate, and limiting rings. The bearing is movably mounted on the upper surface of a bridge pier. A limiting ring is fixedly mounted on the upper surface of the pier at each of the two ends of the bearing in the transverse direction. The two limiting rings cooperate to limit the horizontal position of the bearing on the upper surface of the pier. The support steel plate and the connecting steel plate each include two sets, each respectively disposed on both sides of the centerline of the expansion joint of the bridge beam. The distance between the two sets of support steel plates and the distance between the two sets of connecting steel plates are both greater than or equal to the width of the expansion joint of the bridge beam.

The transverse steel plate and the longitudinal steel plate are arranged in a T-shape and welded and fixed to the upper surface of the supporting steel plate.

The support assembly 1 includes a support 11, a support steel plate 12, a connecting steel plate 13, and limiting rings 14. The support 11 is movably disposed on the upper surface of the pier 3. A limiting ring 14 is fixedly disposed on the upper surface of the pier 3 at both ends of the support 11 in the transverse direction. The two limiting rings 14 cooperate to limit the horizontal position of the support 11 on the upper surface of the pier 3. The support steel plate 12 and the connecting steel plate 13 each include two sets and are respectively disposed on both sides of the center line of the expansion joint 5 of the bridge beam 4. The distance between the two sets of support steel plates 12 and the distance between the two sets of connecting steel plates 13 are both greater than or equal to the expansion joint 5 of the bridge beam 4. The width of the support steel plate 12 is such that the upper end of the support steel plate 12 is fixedly connected to the connecting steel plate 13, the lower end of the support steel plate 12 is movably mounted on the support 11, the upper end of the connecting steel plate 13 is fixedly connected to the lower surface of the bridge beam 4, the enclosure assembly 2 includes a fixed plate 21 and a movable maintenance plate 22, the fixed plate 21 and the movable maintenance plate 22 include several sets (two sets in this embodiment) arranged in a cross pattern and connected to form an annular enclosure surrounding the support assembly 1, the height of the annular enclosure is lower than the height of the lower surface of the bridge beam 4, and there is a gap between the annular enclosure and the support assembly 1, the lower end of the fixed plate 21 is fixedly connected to the upper surface of the pier 3, and the left and right ends of the movable maintenance plate 22 are detachably connected to the adjacent fixed plate 21.

[0029] The connecting steel plate 13 includes a transverse steel plate 131 and a longitudinal steel plate 132. The transverse steel plate 131 and the longitudinal steel plate 132 are arranged vertically in a T-shape, welded and fixed to the upper surface of the supporting steel plate 12. The two sets of transverse steel plates 131 are arranged in parallel on the left and right sides of the center line of the expansion joint 5 of the bridge beam 4.

[0030] The movable maintenance plate 22 and the fixed plate 21 are connected by a tenon and mortise joint structure 23 at their contact ends, and the movable maintenance plate 22 is restricted from moving up and down by the tenon and mortise joint structure 23.

The locking plate 24 is detachably connected to the movable maintenance plate 22 by bolts 25. Since the fixed plate 21 is fixed on the pier 3, the locking plates 24 and the movable maintenance plate 22 are connected to form a ring by bolts 25, and the fixed plate 21 is used to limit the movement, which can prevent the movable maintenance plate 22 from moving in the horizontal direction.

[0031] Bolts 25 include four sets symmetrically positioned on the upper and lower sides of the left and right ends of the locking plate 24. The vertical spacing between the upper and lower sets of bolts 25 on the same end is half the height of the enclosure assembly 2, and the bolts 25 are positioned at 1 / 4 of the longitudinal distance from the centerline of the pier 3. The ends of the bolts 24 are equipped with anti-loosening clips to prevent the bolt body or its matching nut from coming off.

[0032] The support 11 is made of rubber. There is a 3mm gap between the support 11 and the limiting ring 14, which will not affect the limiting ring 14 in limiting the support 11 in the horizontal direction, and the gap makes it easy to remove the support 11 when replacing it.

[0033] The outer contour dimensions of the enclosure component 2 are the same as those of the pier 3. The distance between the upper surface of the enclosure component 2 and the lower surface of the bridge beam 4 is 5-20 mm, and the thickness of the enclosure component 2 is 15-25 mm. The thickness of the supporting steel plate 12 and the connecting steel plate 13 is 20-40 mm.
