Description

Technical Field

[0001] The utility model relates to the technical field of rubber bearings, in particular to a horizontal force dispersion type plate type rubber bearing. Background Art

[0002] Plate rubber bearings are a common type of bridge bearing, used to connect the bridge superstructure (such as the bridge beam) and the substructure (such as piers or abutments), and play the role of supporting and transferring loads. This type of bearing is widely used in small and medium-span bridges because of its easy installation, relatively low cost and easy maintenance.

[0003] A Chinese patent with announcement number CN221501716U discloses a plate-type rubber bearing with a lateral displacement warning structure. It is equipped with an anti-falling structure. When the upper steel plate needs to be installed, the fixed anchor bolt is rotated so that the fixed anchor bolt drives the limit plate to move inside the built-in cavity. Under the action of the fixed anchor bolt, the upper steel plate and the part to be installed are fixed to each other. Under the action of the limit plate, the fixed anchor bolt is prevented from falling off during installation, realizing the anti-falling function of the device, thereby improving the convenience of using the plate-type rubber bearing with a lateral displacement warning structure.

[0004] The above solution uses a rubber seat between two steel plates to buffer the forces acting on the bridge piers. However, since the horizontal forces are buffered solely by the rubber seat itself, not only is the load buffering effect limited, but the wear of the rubber seat itself is also increased. To address this issue, we provide a horizontal force dispersing plate rubber bearing to solve the above problems. Utility Model Content

[0010] A second steel plate is fixedly connected to a protective shell, and elastic support components in a circumferential array are provided on the protective shell, and the telescopic ends of the elastic support components are against the guide seat.

[0011] The rubber seat has two ends respectively mounted on the first steel plate and the second steel plate.

[0012] Furthermore, both the first steel plate and the second steel plate are provided with assembly holes.

[0013] Furthermore, the elastic support assembly includes a guide rod slidably connected to the protective shell, one end of the guide rod is fixedly connected to a fixed block, and the other end of the guide rod is provided with a rotation groove, a roller is rotatably connected in the rotation groove, and the roller rests on the guide seat.

[0014] Furthermore, a support spring is sleeved on the guide rod, and two ends of the support spring are fixedly connected to the fixed block and the protective shell respectively.

[0017] 3) Beneficial effects:

[0018] Compared with the existing technology, this horizontal force dispersion plate rubber bearing has the following beneficial effects:

[0019] The utility model cooperates with the guide rod and the support spring in the protective shell. When the first steel plate moves, the roller can be used to push the guide rod to move laterally and stretch the support spring, thereby effectively dispersing and buffering the load force in the horizontal direction.
