[0001] The present invention relates to the field of bridge expansion devices, and in particular to a reinforced comb-type vibration damping and noise reduction bridge expansion device and method. Background Art

[0002] A bridge expansion device is an important component of a bridge. It is a general term for various devices composed of rubber and steel components installed at the bridge expansion joint to enable vehicles to pass smoothly across the bridge deck and meet the needs of the deformation of the upper structure of the bridge. The performance of the bridge expansion device directly affects the safety of the bridge road.

[0003] In the original technology, the comb plates were often damaged and thus prone to breakage. Summary of the Invention

[0004] Objective of the Invention: To provide a reinforced comb-type vibration damping and noise reduction bridge expansion device and method with better effects. The specific objectives can be seen in the multiple substantial technical effects in the specific implementation part.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A reinforced comb-type vibration damping and noise reduction bridge expansion device, characterized in that the bridge expansion device includes side beams located on both sides of the expansion joint. The side beams are comb-type side beams 1, and the combs of the two groups of side beams are staggered with each other;

[0007] The side beam body of the side beam includes a groove that can fit the edge of the anchor steel plate 8. The side beam body of the left side beam is welded with a support bracket 5; the support bracket 5 is a plate-like structure, the vertical side of the plate-like structure is closely welded to the side beam body, and the upper part of the plate-like structure is welded with the sliding steel plate in the upper and lower sliding steel plates 2 through a support vibration damping device 4;

[0008] The fixed steel plate in the upper and lower sliding steel plates 2 is welded below the comb of the side beam body or on the side beam body;

[0009] There is a gap between the sliding steel plate and the fixed steel plate and they can slide relative to each other;

[0010] The support vibration damping device 4 is used for support and vibration damping. The relative sliding of the sliding steel plate and the fixed steel plate fills the gap in the expansion joint to prevent sundries and rainwater from falling into the expansion joint.

[0011] A further technical solution of the present invention is that the side of the side beam body is fixed by concrete; there is a gap between the fixed steel plate and the comb of the corresponding side beam, and the end of the sliding steel plate in the upper and lower sliding steel plates 2 overlaps in the gap; the length of the sliding steel plate in the upper and lower sliding steel plates 2 is greater than the length of the fixed steel plate.

[0012] A further technical solution of the present invention is that a stopper 6 is welded on the plate-like structure, and the stopper 6 includes a groove in which the vibration damping device 4 can be fixedly supported; the vibration damping device 4 is a spring.

[0013] A further technical solution of the present invention is that on the side of the side beam body contacting the concrete and the anchor steel plate, a high-strength extrusion-resistant rubber is heat-sealed; this high-strength extrusion-resistant rubber is used for the side beam body to be appropriately deformed, extruded, and reset during multi-directional displacement, avoiding direct damage to the concrete.

[0014] A further technical solution of the present invention is that a water stop belt is installed in the expansion joint, and the installation of the water stop belt is any of the following schemes: A. Both sides of the water stop belt are pressed and fixed under the side beam body; B. The water stop belt is pressed and fixed by concrete grouting and bolts.

[0015] A further technical solution of the present invention is that the side beam is a side beam with a vertical steel plate below itself, and this vertical steel plate is the second fender 11. The second fender 11 can be used as a formwork for concrete grouting and can also be used as a support structure for the side beam.

[0016] A further technical solution of the present invention is that a water stop belt is installed in the expansion joint. The installation of the water stop belt is as follows: The water stop belt is a rigid water stop belt, which is made of metal. One side of the rigid water stop belt is fixed on one side of the expansion joint, and the other side is a movable end. The position corresponding to the movable end includes a groove 14 in the expansion joint and the movable end can move left and right in the groove 14.

[0017] A further technical solution of the present invention is that the support bracket 12 is fixedly connected to the support bracket 5 and / or the second fender 11 and / or the rigid water stop belt. The support bracket 12 and / or the rigid water stop belt serve as support structures.

[0018] A further technical solution of the present invention is that the support bracket 5 includes a penetration support auxiliary strengthening and embedding structure 15 arranged horizontally, and the penetration support auxiliary strengthening and embedding structure 15 penetrates through the side beam body and embeds into the concrete.

[0019] An intelligent application method for a reinforced comb-tooth type vibration damping and noise reduction bridge expansion device, characterized in that it uses the reinforced comb-tooth type vibration damping and noise reduction bridge expansion device described in any one of the above.

[0020] This method combines a modular type and a comb-tooth type bridge expansion device; the support bracket 5 provides support force for the comb-tooth structure, making its structure more durable and avoiding the easy damage of the comb-tooth structure.

[0021] The comb-tooth type structure reduces the noise of the expansion device.

[0022] The side beam is a tenon-mortise comb-tooth type special-shaped steel structure. The tenon-mortise structure has a larger contact area with the anchor plate, resulting in better stability. Its combination is then poured together with concrete to enhance the anchoring performance and durability of the expansion device;

[0023] Waterstop: The installation of the waterstop is divided into two forms; the first: by welding the waterstop strip steel bars at the bottom of the side beam, and then fixing the waterstop on the strip through buckles; the second: at the top of the beam end, the waterstop is fixed on the beam end by drilling holes and is firmly fixed after pouring concrete;

[0024] The support and vibration damping is fixed on the support bracket. The upper sliding steel plate is fixed above, and the upper sliding steel plate is fixed at the bottom of the tooth plate of the right side beam. The upper and lower sliding steel plates can slide freely between them;

[0025] The stopper is fixed on the support bracket, which plays the role of fixing and limiting the support and vibration damping device;

[0026] Anchoring steel plate: The anchoring steel plate plays the role of connecting the side beam with the concrete and the pre-embedded steel bars of the bridge, making the expansion device more integral;

[0027] The mudguard prevents slurry leakage during concrete pouring, facilitating construction.

[0028] The present invention adopting the above technical solution has the following beneficial effects compared with the prior art: 1. It combines the advantages of the modular type and the comb-tooth type bridge expansion devices; 2. The design of the support and vibration damping device and the support steel enables the comb-tooth structure to obtain support force, making its structure more durable and avoiding the common problem of the easy damage of the comb-tooth structure. 3. The comb-tooth type structure scientifically utilizes the noise reduction design to reduce the noise of the expansion device. 4. Modular structure: This expansion device can be installed integrally or modularly. The modular expansion device can be divided into multiple parts, which is simple and convenient in production and transportation and also simplifies the construction difficulty. And during later maintenance and replacement, it can be repaired and replaced section by section. BRIEF DESCRIPTION OF THE DRAWINGS
