Description

For both leakage protection and drainage equipment of expansion joint on bridge}

The present invention relates to a water leakage preventing combined use drainage device located in the lower portion of the bridge expansion joint that is stretched according to the displacement and deformation occurring in the upper sleeve during vehicle progression to collect and drain foreign matters such as rainwater or earth and sand. The present invention relates to an invention in which vibration and impact force due to displacement and deformation of an upper sleeve (upper structure) are not directly transmitted to a drainage device, and rapid drainage of rainwater generated in the upper slab is possible.

In general, a bridge through which a heavy vehicle passes is subjected to a large impact load by the weight of the vehicle.

The upper sleeve can be displaced and deformed to prevent damage to the bridges (top plate and pier) caused by the impact load, and at the same time to ensure safe driving. It will be received by the expansion joint that connects it.

The expansion joint device for smoothly receiving the displacement and deformation of the upper sleeve as described above has a joint that is engaged with each other and at the same time the joint including an anchor which is buried in mortar welded to the steel reinforcement forming the skeleton of the upper sleeve, It is made of an elastic joint member (elastic rubber) is fixed to both ends of the coupling groove formed in the joint.

The expansion joint device is connected to the upper sleeve of the bridge, the upper sleeves are connected to each other, so that the bite portion is formed in the gap so that the displacement and deformation in accordance with the generated displacement and deformation conditions to the rain When rainwater is generated on the road surface of the upper sleeve of the bridge, foreign matters, such as soil and nonpoint pollutants mixed with rainwater, flow into the gap between the bites of the expansion joint.

As described above, the rainwater mixed with various foreign matters flows into the gap between the bites, and the rainwater falls down the bridge as it is.

Rainwater falling down as described above flows into public waters and groundwater such as rivers, bays and lakes, and becomes a source of water pollution.

In order to solve the above problems, it has come to install a drainage system to prevent water leakage at the bottom of the expansion joint of the bridge upper slab and to collect and drain rainwater in one place.

The drainage device has been developed in various ways, and patent 10-936969, "Replaceable bridge leak prevention device for replaceable bridges," has been pre-registered as a drainage device in contrast to the present invention.

The pre-registered invention is installed to be located under the connecting portion of the upper slab can prevent water pollution of public waters such as rivers, bays, lakes and groundwater due to rainwater, but the leak prevention device of the pre-registered invention leaks rainwater It is designed to focus only on the thing, so the displacement and deformation of the upper slab of the bridge are transferred directly to the leak prevention device, so when applied to heavy dump trucks or bridges where heavy equipment is frequently operated, the leak prevention device is easily damaged. As a result, the service life is significantly shortened, which makes it difficult to improve the reliability of the leakage preventing device.

Therefore, the conventional leak prevention apparatus mainly used a leak prevention apparatus manufactured using a flexible rubber or synthetic resin material rather than using a leak prevention apparatus using a durable metal material.

Leakage prevention device made of the above material has the advantage of being able to effectively receive the displacement and deformation transmitted from the upper slab of the bridge, it hardens when exposed to natural light for a long time, such as easily broken even a small external impact I had

The present invention was developed in order to solve the disadvantages of the conventional leak-proof combined drainage of the bridge expansion joint device, the purpose of which is installed in the rolling holder of the drip tray to be detachably assembled to the buried frame is fixed to the upper slab One end is installed to be rollable, and the other end is a structure in which the drip tray is installed through the rolling member which is coupled to the rolling holder of the drip tray to be rolled, and the rolling member is rolled correspondingly to the displacement and deformation occurring in the upper slab of the bridge. According to the present invention, it is possible to effectively prevent displacement and deformation transferred directly to the drip tray, and to prevent displacement and deformation, thereby enabling activation of the drip tray product made of a durable metal material as well as durability. The heavy weight bonus can be realized using this excellent metal drip tray. It solves the conventional problem that the water leakage preventing combined drainage caused by the heavy load of the truck or heavy equipment is frequently damaged, and the drain pipe connected to the rainwater outlet because the displacement and deformation do not occur directly in the drip tray. It is to provide the leakproof combined use drainage of the bridge expansion joint device which can secure the reliability of the combined use of the leak preventive system by securing the assembly stability of the system.

The present invention for achieving the above object, including a fixed bolt welded to the reinforcing bar reinforcing the slab of the slab, bent from the vertical wall is formed in a horizontal direction bent from the upper and lower plates to the end narrowed trapezoidal buried A frame;

The upper and lower plates forming a trapezoid corresponding to the upper and lower plates of the buried frame are bent from the vertical plate formed with the wedge insertion grooves so that the buried frame can be fixed in close contact with the buried frame, and a cutting hole is formed between the braces formed between the upper and lower plates. A drip tray mounting platform including a rolling holder formed therein;

A rolling member having a rolling bar coupled to a rolling holder formed between the bracing mounts at an upper end thereof, and having a rolling holder having a rolling bar coupled with a rolling hinge formed at a lower end thereof;

A rolling hinge having an upper rolling bar coupled to a rolling hole of the rolling member and a lower rolling bar coupled to a rolling holder of a rain gutter in a shape corresponding to the device;

Rolling holders with cutout holes are formed at both upper ends to enable coupling of the lower rolling bars of the rolling hinges, and at least one rainwater discharge port having a rainwater discharge port connected to a drain pipe for collecting and draining rainwater is formed on the bottom surface. Characterized in that made.

The drip tray is characterized in that it is firmly fixed to the buried frame by a wedge bar fitted into the wedge insertion groove of the vertical plate.

The rolling member is characterized in that it has a hinge protection plate for covering the rolling hinge on the upper side of the rolling holder and neighboring points.
