Description

{EXPANSION JOINT CONSTRUCTION METHOD WITH NON WELDING AND NOISE FREE CHARACTERISTICS}

The present invention relates to a method for constructing a weldless, noiseless expansion joint device, and more specifically, to a method for constructing a weldless, noiseless expansion joint device having a weldless, noiseless characteristic by having an upper frame and a lower frame assembled in a manner that allows for partial maintenance.

In general, the slab included in the superstructure of a bridge contracts or expands along its length due to temperature changes during the winter and summer, and numerous internal and external factors of the bridge, such as changes in the surrounding temperature, live load application, earthquakes, contraction, stress relaxation, and subsidence, trigger relative movement between the superstructure and the substructure, and this movement can vary in the direction of the bridge axis, in the direction perpendicular to the bridge axis, or in the rotation about the bridge axis or in the direction perpendicular to the bridge axis.

Accordingly, since deformation of the slab and damage to the bridge may occur due to expansion or contraction of the slab, an expansion joint is required between the slabs to accommodate expansion and contraction of the slab.

Accordingly, expansion joints are installed in the upper structure of the bridge to absorb structural deformations such as temperature changes, shrinkage, and creep, to minimize impact force due to vehicle loads while ensuring smooth vehicle operation, and to have a waterproofing function to prevent drainage from being discharged toward the abutments and piers.

The above expansion joints can be broadly classified into open joints, filled joints, sliding plate joints, finger plate joints, sawtooth plate joints, compressing seal joints, strip seal joints, shotte seal joints, plank seal joints, and modular joints.

Although these expansion joints are small components in bridge structures, many problems can occur when they do not function properly. The problems of conventional expansion joints are as follows.

First, expansion joints are devices that smoothly accommodate expansion due to temperature changes, drying shrinkage and creep due to the age of concrete, and movement and rotation of the superstructure due to live loads. However, among bridge components, they are the most frequently damaged due to increased traffic volume, negligent construction, immature maintenance, and failure to maintain them in a timely manner.

Second, if water leaks through the expansion joint, the structures underneath will deteriorate, and if the expansion joint cannot move, excessive stress will be generated in many bridge members, making them easily damaged.

Third, if there is damage to the expansion joint, the rubber material or sealant inside will loosen, tear, break, or be damaged, and the drainage gutter underneath will be filled with stones and foreign substances from the catch basin, preventing smooth drainage and expansion.

Fourth, if damage occurs to other expansion joints, loosening and rusting of other steel components such as steel plates, sections, and anchor bolts, cracking and peeling of concrete, rusting of structural steel and exposure of reinforcing bars, damage due to noise and vibration from passing vehicles, and signs of bridge subsidence may occur.

In particular, since conventional expansion joint devices are produced and installed with a focus only on the amount of change, there was a problem that noise inevitably occurred when the vehicle was driving due to structural limitations.

Accordingly, a finger plate-type expansion joint device with a vent hole formed therein is being developed to reduce noise, and the finger plate-type expansion joint device as described above is designed to reduce noise generated when a vehicle is driven by directing it downward through the vent hole or through a resonance phenomenon.

As a technology related to this, Korean Patent Publication No. 10-2119545 discloses a method for manufacturing a noiseless expansion joint, and Korean Patent Publication No. 10-2605198 discloses a method for constructing a noiseless expansion joint.

However, the above-mentioned method of manufacturing and constructing an expansion joint device has the problem that partial maintenance is difficult because some components are fixed to each other by welding, which increases the replacement cost and increases the construction cost, and that a lot of time and manpower must be invested during installation and replacement.

At this time, in the upper body fixing step (S400), the other end of the alternating plates (210) of a pair of the upper bodies (200) can be arranged on the upper side of the lower body (100) so as to overlap and alternate in the front-back direction, and can be fixed through the fastening member (400) in a state in which the parts of the upper body (200) are welded through the joining member (700).

The upper body (200) may further include a reinforcing plate (240) that is in contact with the other end side of the alternating plate (210). In addition, the reinforcing plate (240) may be formed as a pair, and may include a first reinforcing plate (241) that is in contact with the other end side of the first plate (211) and a second reinforcing plate (242) that is in contact with the other end side of the second plate (212). In addition, the reinforcing plate (240) may be installed on the alternating plate (210) and the fixing plate (230) in the upper body assembling step (S300) or the upper body fixing step (S400).

Although the present invention has been described with specific details such as specific components and limited example drawings, these have been provided only to help a more general understanding of the present invention, and the present invention is not limited to the above-described embodiment, and those skilled in the art to which the present invention pertains can make various modifications and variations from this description.

Therefore, the idea of the present invention should not be limited to the described embodiments, and all things that are equivalent or equivalent to the scope of the claims described below as well as the same shall fall within the scope of the idea of the present invention.
