Description

Bridge shoe for preventing a slanting

The present invention relates to the improvement of the bridge system that is installed on the top of the bridge to support the top plate of the bridge to receive the load and deformation of the top plate, in particular, the lubrication that improved the ability to respond even if the top plate is lifted by the operation of hydraulic or wind power The present invention relates to a preventive teaching device.

Bridges that connect both eyes across the sea, as well as rivers and rivers, generally have a structure in which the tops are placed on the pier, and even a cable-stayed bridge (suspension bridge) that is installed without a pier, supports the tops in the middle or both sides (both shifts or columns). Since it is installed, it does not deviate from the structure of the top plate and the pier basically.Because a heavy vehicle or a trailer, such as a person, a vehicle, or a heavy load passes through the bridge, the dynamic load that changes every moment is exerted. As the top plate gets longer, the elongation and contraction amount is increased due to the change of season and heat deformation according to the crossover. This means that the contact area between the top plate and the pier can be changed, so that the bridge can have sufficient load bearing capacity and can enjoy sufficient lifespan. In general, a device called a bridge device is installed on top of the bridge And corresponding to the displacement of the plate and to support the top plate.

These chair units are reinforced with a pot bearing type and a steel plate. There is a pad shoe (Pad shoe elastic type) of the bridge device made of elastic rubber support, the present invention is particularly applied to the pad shoe type of the bridge device, the conventional design developed so far is the force from the outside If it works, there is no structure corresponding to the problem that can be predicted at all, but the conventional general teaching apparatus described in the prior art to contrast with the advantages of the present invention as follows.

The conventional design, as shown in Figure 3, the upper plate 1 of the enemy via the anchor bolt 12 on the upper plate of the bridge and the lower plate (2) of the enemy seated through the anchor bolt 22 on the pier And pads 3 interposed between the upper and lower plates 1 and 2 to support a compressive force and a deformation force, wherein the upper and lower plates 1 and 2 have stoppers 13 and 23 having a predetermined shape as necessary. It is attached (exemplary one-way movable end in Fig. 3) to be used as a movable end or a fixed-end stabilization device.

In the above-described constitution apparatus of the conventional design, the upper and lower plates 1 and 2 respectively integrally mounted on the upper plate and the pier are relatively moved with each other according to the displacement of the upper plate, and the pad 3 interposed in the center is, for example, an iron core ( 32) has a built-in compression rubber 31, thereby supporting the deformation force and the load of the upper plate to the pier side as appropriate, so that it can be properly adapted to the load and deformation force foreseen under normal circumstances, Depending on the position of the pier to be seated, the resilient bearing can be used as an enemy with a fixed end and a longitudinal free end (FIG. 3).

However, the prior art devises a top plate when a force is applied from the outside, such as a submerged bridge, sometimes submerged in water, or by wind power such as a typhoon. In case of rising, there is a problem that the top plate and the pier are separated by more than the design distance, and thus, a bridge device or a pad having a cushioning function installed therebetween may be removed from its position and thus may not perform a given function.

In particular, this problem is sharply raised in the advanced chair system to enhance the function of the chair device, for example, in the 'bridge bridge device' of the patent inventor No. 206637, the patent inventor of the invention has an additional configuration to improve the lubrication action Although the deformation device was able to absorb the large deformation sufficiently, the side effect was rather lost due to the interview between the pad and the upper plate to improve the lubrication effect, and according to the patent application No. 97-72562, Although the similar structure proposed in the present invention is partially adopted in the improved teaching device, it is a structure for protecting bearings, which are embedded precision parts, and is not a dedicated structure for improving the resilience as in the present invention. The invention is for port bearings, so it is still seen in pad shoe type chairs such as the present invention. There is no cost to develop a specified structure to achieve low.

The present invention was developed to solve the above problems, the problem is that the bridge is installed in the water or applied to the bridge with a high levitation force in the face of strong winds while having all the functions of the ordinary general bridge device without loss. It has a structure suitable for use as a device, and was developed to minimize economics by minimizing the configuration to have such additional functions. The present invention was completed to provide a structure suitable for the desch-type teaching device, which will be described in more detail according to the drawings.
