Description

Technical Field

[0001] The invention relates to the technical field of bridge expansion joint waterproofing, and in particular to a bridge expansion joint filling device. Background Art

[0002] Bridge expansion joints are structural joints set between the two ends of beams, between beam ends and abutments, or at the hinged positions of bridges. Their purpose is to adapt to the deformation requirements of the bridge deck. Its key functions are: on the one hand, it can effectively absorb the displacement or displacement caused by the expansion and contraction of the bridge deck due to temperature changes; on the other hand, it can also adjust the displacement between the superstructures caused by vehicle loads and bridge construction materials, and ensure the stability of their connection, thereby ensuring that the bridge can be used normally and has good durability.

[0003] In the past, expansion joints were generally filled with polyurethane materials, and waterproof strips were set inside the polyurethane. However, in actual applications, at the connection interface between the beam and the polyurethane filling part, due to the direct contact between the polyurethane filling structure and the beam, there is a lack of effective buffering, which makes the polyurethane filling body here very prone to fatigue deformation during long-term and frequent stress. The waterproof strip is also subjected to continuous stress, and its durability is greatly reduced, which leads to the failure of the water-stopping function, causing water leakage under the bridge and damage to the edge of the concrete. Moreover, once damage occurs, it is extremely difficult to repair, and the expansion joint often needs to be removed as a whole, which not only consumes a lot of manpower, material resources and time costs, but also has a certain degree of impact on the normal passage of the bridge. Summary of the invention

[0004] In view of this, the present invention provides a bridge expansion joint filling device to solve the problem of poor waterproofing effect at the expansion joint and the connection in the prior art.

[0006] Two beam bodies, an expansion joint is formed between the two beam bodies;

[0007] A structural layer, arranged on the beam body at both sides of the expansion joint;

[0008] The deformation layer includes a telescopic layer and two elastic layers, wherein the telescopic layer is arranged on the expansion joint, and at least a part of the area is respectively covered on the structural layers on both sides, the two elastic layers are arranged on both sides of the telescopic layer, and are on the same horizontal plane as the telescopic layer, and the telescopic layer and the elastic layer are separately arranged.

[0009] Optionally, the elastic layer is at least partially overlapped on the telescopic layer.

[0013] A height positioning member is fixedly arranged on a side of the structural layer close to the expansion joint by the first fixing member, and a top of the height positioning member is at the same horizontal height as the structural layer in the vertical direction.

[0014] Optionally, a waterproof coating is provided on the height positioning member, and the connecting corners between the beam body and the structural layer are chamfered and filled with waterproof material.

[0015] Optionally, a second fixing structure is provided on a side of the structural layer away from the expansion joint, and the second fixing structure includes:

[0016] An anchor seat, the anchor seat is fixedly connected to the beam body, and the top of the anchor seat is at the same level as the structural layer;

[0017] The second fixing member has one end fixedly connected to the anchor seat and the other end arranged in the elastic layer.

[0018] Optionally, it also includes:

[0024] Beneficial Effects

[0025] The bridge expansion joint filling device provided by the present invention comprises two beam bodies, an expansion joint is formed between the two beam bodies; a structural layer is arranged on the beam bodies on both sides of the expansion joint; a deformation layer comprises a expansion layer and two elastic layers, the expansion layer is arranged on the expansion joint, and at least part of the area is respectively covered on the structural layers on both sides, the two elastic layers are arranged on both sides of the expansion layer, and are on the same horizontal plane as the expansion layer, and the expansion layer and the elastic layer are arranged separately.

[0026] The structural layer provides a supporting foundation for the device. The expansion layer of the deformation layer can adapt to the deformation of the expansion joint caused by temperature changes, vehicle loads and other factors, and effectively absorb the expansion and contraction displacement of the bridge deck. The elastic layers on both sides are in contact with the bridge structure. Compared with the traditional expansion joint structure filled with polyurethane material and built-in waterproof strips, the deformation of the connection is transferred to the contact between the elastic layer and the expansion layer. Since both the elastic layer and the expansion layer have good deformation capacity, they can flexibly deform according to the direction and magnitude of the force. With its good elastic recovery characteristics, the elastic layer can be moderately compressed when subjected to pressure, and quickly rebound to its initial state after the pressure is relieved, effectively avoiding the fatigue deformation of the polyurethane filling body and the poor durability of the water stop strip under long-term use, which in turn causes water leakage under the bridge and damage to the edge of the concrete, reducing the impact on the normal passage of the bridge. In addition, the expansion layer and the elastic layer are set separately, and there is no need to dismantle the entire layer in case of local damage, which reduces the maintenance cost and difficulty, and ensures the normal use and durability of the bridge.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0035] According to an embodiment of the present invention, a bridge expansion joint filling device is provided, comprising:

[0036] Two beam bodies 1, an expansion joint is formed between the two beam bodies 1;

[0037] The structural layer 2 is arranged on the beam body 1 on both sides of the expansion joint;

[0038] The deformation layer 3 includes a telescopic layer 32 and two elastic layers 31. The telescopic layer 32 is arranged on the expansion joint, and at least part of the area is respectively covered on the structural layers 2 on both sides. The two elastic layers 31 are arranged on both sides of the telescopic layer 32 and are on the same horizontal plane as the telescopic layer 32. The telescopic layer 32 and the elastic layer 31 are separately arranged.

[0039] It should be noted that the structural layer 2 is a concrete layer. Concrete has good compressive strength and stability, can provide a solid and reliable foundation support for the entire device, effectively disperse the various stresses transmitted by the beam body 1, and ensure that the structural layer 2 itself is not easily deformed or damaged during long-term use, thereby ensuring the overall structural integrity of the expansion joint filling device.

[0040] It should be noted that the expansion layer 32 can be made of polyurethane material. Polyurethane material has excellent elasticity and flexibility, and can well adapt to the repeated expansion and contraction deformation of the bridge expansion joint due to temperature changes, vehicle loads and other factors. Its good elastic recovery performance ensures that it can still fit the gap tightly after deformation, effectively preventing debris from entering the gap, and ensuring the normal working state of the expansion joint.

[0041] It should be noted that the elastic layer 31 is mainly made of polyurethane material and mixed with other materials. As the basic component, the polyurethane material ensures that it has good elasticity and flexibility, so that it can effectively cooperate with the expansion layer 32 to cope with the deformation requirements of the bridge expansion joint, and the other mixed materials further optimize the comprehensive performance of the elastic layer 31. For example, the added high-strength fiber material can significantly enhance its tensile strength, so that the elastic layer 31 is not easy to break or tear when subjected to a large external force, and effectively resists the impact force generated by frequent vehicle driving and the stress concentration caused by drastic temperature changes.

[0042] In the bridge expansion joint filling device provided by the embodiment of the present invention, the structural layer 2 provides a supporting foundation for the device, and the expansion layer 32 of the deformation layer 3 can adapt to the deformation of the expansion joint caused by temperature changes, vehicle loads and other factors, and effectively absorb the expansion and contraction displacement of the bridge deck, while the elastic layers 31 on both sides are in contact with the bridge structure. Compared with the traditional expansion joint structure filled with polyurethane and built-in waterproof strips, the deformation of the connection is transferred to the contact between the elastic layer 31 and the expansion layer 32. Since both the elastic layer 31 and the expansion layer 32 have good deformation capabilities, they can flexibly deform accordingly according to the direction and magnitude of the force. With its good elastic recovery characteristics, the elastic layer 31 can be moderately compressed when subjected to pressure, and quickly rebound to the initial state after the pressure is relieved, effectively avoiding the fatigue deformation of the polyurethane filling body and the poor durability of the water stop strip under long-term use, thereby causing the problem of water leakage under the bridge and damage to the edge of the concrete, reducing the impact on the normal passage of the bridge, and the expansion layer 32 and the elastic layer 31 are separately arranged, and there is no need to dismantle the entire layer in the event of local damage, which reduces the maintenance cost and difficulty, and ensures the normal use and durability of the bridge.

[0043] Furthermore, the elastic layer 31 is at least partially overlapped on the telescopic layer 32 .

[0044] It is easy to understand that, on the one hand, this setting enhances the integrity of the connection between the expansion layer 32 and the elastic layer 31, so that the two can work together when dealing with the deformation of the bridge expansion joint, avoiding the occurrence of interlayer separation or displacement inconsistency. On the other hand, the partial overlap design expands the contact area between the elastic layer 31 and the expansion layer 32, which can further prevent external moisture, dust and other impurities from entering the expansion joint through the gap, and play a better sealing and protective role for the expansion joint, reducing the probability of material damage and expansion joint failure caused by impurity erosion, thereby extending the service life of the filling device.

[0045] Furthermore, the elastic modulus of the elastic layer 31 is smaller than the elastic modulus of the expansion layer 32 .

[0046] It should be noted that the expansion layer 32 with a higher elastic modulus can provide a stronger ability to resist deformation when facing external forces, preventing excessive deformation from causing damage to the expansion layer 32 and the entire device. At the same time, due to the relatively rigid support of the expansion layer 32, the elastic layer 31 can exert its good flexibility to adapt to slight deformation. The two complement each other, ensuring that the bridge expansion joint always maintains a good working condition during long-term use, reducing bridge structural diseases caused by expansion joint problems, and ensuring the structural safety and service life of the bridge.

[0047] Furthermore, a first fixing structure is provided on one side of the structural layer 2 close to the expansion joint, and the first fixing structure includes:

[0048] A first fixing member 41 is disposed on a side of the beam body 1 close to the expansion joint, one end of the first fixing member 41 is fixedly connected to the beam body 1, and the other end is disposed in the structural layer 2;

[0049] The height positioning member 42 is fixedly arranged on a side of the structural layer 2 close to the expansion joint by the first fixing member 41 , and the top of the height positioning member 42 is at the same level as the structural layer 2 in the vertical direction.

[0050] Specifically, in this embodiment, the first fixing member 41 is a fixing bolt, and one end thereof connected to the beam body 1 is provided with a first fixing nut, and the first fixing nut is welded firmly to the beam body 1 in advance, so that the fixing bolt and the beam body 1 are fixed by screwing together. The height fixing member is an L-shaped member, and a through hole is provided on one side arm thereof. With the cooperation of the second fixing nut and the first fixing nut, the L-shaped member is fixed on the fixing bolt. The other side arm of the L-shaped member is arranged in a vertical direction, and this side arm and the beam body structure on the same side are enclosed together to form a space for casting the structural layer 2. In actual operation, by rotating and adjusting the fixing bolt and the second fixing nut, the casting thickness of the structural layer 2 can be adjusted to ensure that the molding quality of the structural layer 2 meets the design requirements, reduce the risks of various potential problems caused by the thickness deviation of the structural layer 2, and ensure the safety and durability of the bridge during long-term use.

[0051] In an optional embodiment, the first fixing member 41 may be an expansion bolt, which is inserted into a pre-drilled hole in the beam body 1 during installation, and the nut is tightened to expand the tail expansion sleeve and anchor it to the beam body 1. There is no need to weld the fixing nut, which simplifies the process and has a stronger anchoring force on the high-grade concrete beam body 1; or a chemical anchor bolt is used, which uses chemical agents to bond the screw and the beam body 1 into one body, with flexible requirements on the hole diameter and depth, and better corrosion resistance and stability in a humid or chemically corrosive environment. In terms of height fixing parts, a U-shaped slot can be used instead of an L-shaped part. The two side walls of the U-shaped slot are provided with threaded holes. After being put on the fixing bolt, it is fixed with a nut. A casting space is formed between the bottom and the beam body 1, and the casting thickness of the structural layer 2 is accurately controlled by adjusting the nut. Here, no specific limitation is made to the first fixing structure.

[0052] Furthermore, a waterproof coating is provided on the height positioning member 42 , and the connection corners between the beam body 1 and the structural layer 2 are chamfered and filled with a waterproof material 43 .

[0053] It is easy to understand that the waterproof coating on the height positioning piece 42 can effectively prevent rainwater and other external moisture from penetrating into the connection between the structural layer 2 and the beam body 1 along the height positioning piece 42, avoiding steel bar corrosion and concrete structure damage caused by moisture intrusion, thereby extending the service life of the structural layer 2 and the entire expansion joint filling device.

[0054] The chamfering of the connection corner between the beam body 1 and the structural layer 2 and the use of waterproof material 43 to fill it further enhances the waterproof performance of this position. The chamfering treatment can reduce the possibility of water accumulation and stress concentration, and the filling of waterproof material 43 forms a waterproof barrier to prevent water from penetrating from the connection corner, thereby ensuring the stability of the bridge expansion joint under complex climatic conditions and long-term use, reducing the maintenance cost and safety hazards caused by water damage, and ensuring the durability and safety of the bridge structure.

[0055] Specifically, the waterproof coating can be made of polyurethane waterproof coating or acrylic waterproof coating. The polyurethane waterproof coating forms a dense and tough coating film, which can effectively block water penetration and is easy to construct. It can form a uniform protective layer on the surface of the height positioning member 42 by brushing or spraying. The acrylic waterproof coating has good UV resistance, is not easy to age or powder under long-term sunlight, and can maintain its waterproof function for a long time.

[0056] Specifically, the waterproof material 43 may be waterproof mortar, which is a composite material in which special ingredients such as waterproofing agent and polymer emulsion are added to ordinary cement mortar. It has good anti-seepage performance and can effectively prevent moisture from penetrating into the structure through the pores. In an optional embodiment, silicone sealant may also be used, which has excellent weather resistance and can remain stable in a wide temperature range (such as -40°C to 80°C), effectively coping with the hot and cold changes in the environment where the bridge is located, and has strong adhesion to various materials such as concrete and metal, and can form a reliable seal at the connection corner between the beam body 1 and the structural layer 2 to prevent moisture intrusion.

[0057] Furthermore, a second fixing structure is provided on one side of the structural layer 2 away from the expansion joint, and the second fixing structure includes:

[0058] An anchor seat 51, the anchor seat 51 is fixedly connected to the beam body 1, and the top of the anchor seat 51 is at the same level as the structural layer 2;

[0059] One end of the second fixing member 52 is fixedly connected to the anchor seat 51 , and the other end is disposed in the elastic layer 31 .

[0060] It should be noted that the anchor seat 51 is connected to the beam body 1 and its top is flush with the structural layer 2, providing basic support for the entire fixed structure, effectively dispersing the stress from the elastic layer 31, and preventing damage to the structural layer 2 due to excessive local force. One end of the second fixing member 52 is fixed to the anchor seat 51, and the other end is deeply inserted into the elastic layer 31, which enhances the integrity of the connection between the elastic layer 31 and the structural layer 2 and the beam body 1. When the bridge is subjected to complex working conditions such as frequent vehicle driving and temperature changes, this connection method can make the elastic layer 31 function more stably, avoid displacement or falling off, thereby ensuring the structural stability and reliability of the expansion joint filling device.

[0061] Specifically, a bolt hole is provided on the anchor seat 51, and the second fixing member 52 is a bolt, one end of which is threadedly connected to the anchor seat 51, and the other end is a bolt head, which is directly set in the elastic layer 31. The threaded connection method not only ensures the firmness of the connection, but also facilitates installation and adjustment during construction. The screw-in depth of the bolt can be controlled according to actual conditions to achieve the best fixing effect. The other end is designed as a bolt head, which is directly set in the elastic layer 31. The presence of the bolt head increases the contact area with the elastic layer 31, so that it can more evenly transfer the tension or pressure to the elastic layer 31 when it is subjected to force, avoiding stress concentration and causing local damage to the elastic layer 31.

[0062] Furthermore, it also includes:

[0063] The telescopic layer fixing member 53 has one end fixedly connected to the second fixing member 52 and the other end disposed in the telescopic layer 32 .

[0064] It is easy to understand that one end of the expansion layer fixing member 53 is connected to the second fixing member 52, and the other end is embedded in the expansion layer 32, so that the expansion layer 32 and the elastic layer 31 are tightly fixed together. When the bridge is subjected to various complex external forces such as vibration and impact caused by vehicle driving and expansion and contraction deformation caused by temperature changes, the expansion layer fixing member 53 can limit the excessive displacement of the expansion layer 32, so that it can work better with the elastic layer 31, evenly disperse the stress, ensure that the expansion joint can always maintain good sealing and deformation adaptability, effectively prevent debris from entering the expansion joint, and thus ensure the safe and stable operation of the bridge structure, and improve the durability and reliability of the bridge.

[0065] Specifically, in this embodiment, the telescopic layer fixing member 53 includes a horizontal limiting portion and an L-shaped fixing portion. The horizontal limiting portion is parallel to the structural layer 2, and a through hole is provided at one end thereof, and is installed between the anchor seat 51 and the elastic layer 31 through the second fixing member 52. The other end of the horizontal limiting portion extends to the adjacent area of ​​the structural layer 2 and the telescopic layer 32, and an L-shaped member is provided at this end, and the L-shaped member penetrates into the telescopic layer 32. The L-shaped member has a large surface area, and its shape and size are highly adapted to the internal structure of the telescopic layer 32, and can fit tightly with the telescopic layer 32 on a large contact surface, thereby ensuring a stable and reliable connection effect, and enhancing the stability and integrity of the telescopic layer 32 during the expansion and contraction process of the bridge.

[0066] Furthermore, it also includes a stiffener 54, which is arranged on a side of the anchor seat 51 close to the expansion joint, and the stiffener 54 is fixedly connected to the anchor seat 51 and the beam body 1 respectively.

[0067] It is easy to understand that when the bridge is subjected to huge loads generated by vehicle travel, frequent vibrations, and expansion and contraction stresses caused by temperature changes, the stiffeners 54 can effectively enhance the stability and bearing capacity of the anchor seat 51 .

[0068] Furthermore, it also includes:

[0069] The paving layer 6 is arranged on the deformation layer 3 .

[0070] It is easy to understand that the pavement layer 6 can provide a smooth and continuous surface for the expansion joint of the bridge, improve the driving comfort and safety, avoid the vehicle from bumping or jumping when passing through the expansion joint, and reduce the damage to the vehicle tires and suspension system.

[0071] Specifically, the pavement layer 6 is an asphalt layer.

[0072] Furthermore, it also includes a seam cover plate 7, which is arranged between the structural layer 2 and the deformation layer 3 and covers the expansion joint.

[0073] Here, a construction method of a bridge expansion joint filling device in an embodiment of the present invention is provided, firstly, the first fixed structure is fixed to the steel beam, the anchor device is positioned and placed according to the width of the expansion layer 32, the height positioning member 42 is adjusted to be equal to the anchor device of the second fixed structure, and the gap between the beam body 1 and the structural layer 2 is filled with waterproof mortar and chamfered; then, concrete is poured, and after solidification, the expansion layer 32 and the elastic layers 31 on both sides are installed in sequence, and finally, asphalt is paved on the top surface.

[0074] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
