Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a fine-adjustable bridge support. Background Art

[0002] Taking the maglev rail transit bridge as an example, during the construction and operation of the maglev rail transit bridge, the smoothness requirements of the line are very strict. If the bridge foundation settles, it will affect the line shape and overall stress of the bridge, resulting in serious consequences.

[0003] In this regard, the method of adjusting the height of the bearings is often used to compensate for the settlement of the foundation to ensure the overall shape of the bridge and the smoothness of the line. However, the current bearing height adjustment is mainly achieved through wedge height adjustment. The inclined surface of the wedge can achieve infinite height adjustment, but the height adjustment amount of this method is limited due to the slope of the wedge.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a fine-tunable bridge bearing is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a fine-adjustable bridge support to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fine-adjustable bridge bearing, comprising a lower bearing and an adjustment component, wherein an adjustment component is welded and fixed in the middle of the lower bearing, and the adjustment component comprises a fixed seat, an inner slot, a cone, a casting port, a through hole and an outer plug-in ring, an inner slot is opened in the middle of the fixed seat, and a cone is opened at the bottom of the inner slot, a casting port is connected to the side of the inner slot, and through holes are evenly distributed on the top of the inner slot, and an outer plug-in ring is opened on the periphery of the inner slot.

[0007] Furthermore, the outer insert ring has a smaller depth than the inner slot, and the outer insert ring is concentrically arranged with the inner slot.

[0008] Furthermore, lower anchor bolts are provided at four corners of the lower support, and the lower support is connected to the bridge pier through the lower anchor bolts.

[0009] Furthermore, inwardly recessed limiting countersunk holes are provided on both sides of the lower support, and a lifting cylinder is installed inside the limiting countersunk holes.

[0010] Furthermore, an upper support is arranged above the lower support, and upper anchor bolts are arranged at four corners of the upper support, and the upper support is connected to the abutment through the upper anchor bolts.

[0011] Furthermore, a pillar is welded and fixed in the middle of the upper support, and an anchor rod is integrally fixed to the end of the pillar, and the anchor rod matches the cone opening at the bottom of the inner slot.

[0012] Furthermore, a sleeve is provided on the outside of the pillar, and the sleeve cooperates with the outer plug-in ring.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, cement mortar is poured into the inner slot through the pouring port, and the cement mortar accumulates at the bottom of the cone mouth under the action of gravity. Then the upper support is lowered, and under the extrusion cooperation of the anchor rod and the cone mouth, the unsolidified cement mortar diffuses in the inner slot, enters the outer plug-in ring through the through hole, and fills the inner side of the sleeve sleeved at the end of the pillar. Among them, the setting of the cone mouth can reduce the use of cement mortar. Under the extrusion cooperation of the anchor rod and the cone mouth, the cement mortar diffuses in the inner slot to wrap the pillar and fill the inner side of the outer plug-in ring. After the cement mortar solidifies, the pillar will be tightly combined with the fixing seat to improve the stability, and the setting of the outer plug-in ring can prevent the overflow of cement mortar and reduce material waste.

[0015] 2. When the utility model is in use, the base of the jacking cylinder is placed in the limit countersunk holes on both sides of the lower support. The setting of the limit countersunk holes is used to ensure the stability of the installation position of the jacking cylinder and the symmetry of the force application position. By lifting the upper support, the pillar is lifted from the corresponding inner slot, thereby increasing the distance between the lower support and the upper support. The distance adjustment between the lower support and the upper support is used to compensate for the settlement of the foundation to ensure the overall shape of the bridge and the smoothness of the line.
