Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge deck connection structure, bridge deck assembly and bridge for forming narrow wet joints. Background Technology

[0002] In recent years, precast bridge technology has received widespread attention and application in the field of bridge construction. In particular, the introduction of ultra-high performance concrete (UHPC) has fully demonstrated the advantages of precast bridge decks for steel-concrete composite beams. Despite the numerous advantages of precast bridge decks, they still face some technical bottlenecks in practical applications, especially in the treatment of joints between deck sections. Traditional cast-in-place construction methods for wet joints in bridge decks have significant problems: First, the width of the wet joints is relatively large, leading to an increase in the amount of concrete poured and requiring a longer curing time, thus extending the construction period and failing to meet the demands of rapid construction. Second, the reinforcement arrangement in the wet joint section is complex, with small lateral spacing between connecting bars, making it easy for bars to cross and interfere during construction, resulting in difficulties in on-site installation and low construction efficiency. Furthermore, traditional wet joints fail to fully optimize the shear resistance of the joints in their structural design; directly reducing the width of the wet joints can cause the strength of the bridge deck at the wet joint to fail to meet design standards and service requirements. Utility Model Content

[0003] The purpose of this invention is to overcome the technical problems of existing bridge deck wet joints being too wide, having a large amount of concrete cast-in-place resulting in long curing periods, and having low construction efficiency, and to provide a bridge deck connection structure, bridge deck components, and bridge for forming narrow wet joints.

[0004] In a first aspect, the present invention provides a bridge deck connection structure for forming a narrow wet joint, comprising a wet joint and a plurality of embedded grooves. The wet joint is formed between the opposite end faces of two adjacent bridge decks. The embedded grooves are spaced apart along the length of the wet joint on the end faces of the bridge decks. The plurality of embedded grooves are correspondingly arranged on both sides of the wet joint and communicate with the wet joint. Shear reinforcement bars are connected between two embedded grooves correspondingly arranged on both sides of the wet joint. The sidewalls of the embedded grooves are formed as corrugated surfaces.

[0005] This application involves creating multiple pre-embedded grooves side-by-side on the end faces of the bridge decks on both sides of the wet joint, connecting these grooves to the wet joint itself. When the bridge decks are joined, the pre-embedded grooves on both sides of the wet joint correspond one-to-one. Concrete can be integrally poured into the wet joint and the pre-embedded grooves during the wet joint pouring process. Simultaneously, shear reinforcement bars are embedded in the corresponding pre-embedded grooves on both sides to connect them, thus ensuring the shear resistance of the wet joint. Furthermore, when precasting the concrete bridge deck, the sidewalls of the pre-embedded grooves are cast as corrugated walls. After the wet joint is poured, a corrugated construction joint is formed between the newly poured concrete and the sidewalls of the pre-embedded grooves, ensuring the tensile strength of the bridge decks on both sides. Based on this, the distance between the bridge decks on both sides can be reduced when the bridge decks are joined, thus reducing the width of the wet joint without affecting its mechanical properties. Therefore, the amount of concrete poured into the wet joint can be significantly reduced, curing time shortened, and construction efficiency improved.

[0006] Preferably, a corrugated plate is attached to the side wall of the pre-embedded groove, and the corrugated plate is connected to the corrugated surface of the side wall of the pre-embedded groove.

[0007] Preferably, a plurality of first reinforcing bars are embedded in the bridge deck, and the plurality of first reinforcing bars are parallel to the surface of the bridge deck and perpendicular to the wet joint. One end of the first reinforcing bar extends into the pre-embedded groove and is connected to the shear reinforcement.

[0008] Preferably, a second reinforcing bar is provided at the bottom of both the first reinforcing bar and the shear reinforcing bar in the pre-embedded groove, and the second reinforcing bar is arranged intersecting with the first reinforcing bar and the shear reinforcing bar.

[0009] Preferably, the pre-embedded groove extends through to the upper surface of the bridge deck in the thickness direction.

[0010] Preferably, the depth of the pre-embedded groove in the thickness direction of the bridge deck is 40% to 60% of the thickness of the bridge deck.

[0011] In a second aspect, the present invention provides a bridge deck assembly comprising a plurality of bridge decks disposed in abutment, wherein a bridge deck connection structure for forming a narrow wet joint as described above is provided between two adjacent bridge decks.

[0012] Preferably, the bridge deck is provided with a plurality of shear keyways, which extend through the bridge deck along the thickness direction of the bridge deck.

[0013] In a third aspect, the present invention provides a bridge, including a steel beam and the bridge deck assembly, the bridge deck assembly being erected on the steel beam.

[0014] Preferably, a spacer is provided between the steel beam and the bridge deck assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a bridge deck connection structure, bridge deck assembly, and bridge for forming narrow wet joints. Multiple pre-embedded grooves are opened side-by-side on the end faces of the bridge decks on both sides of the wet joint, and these grooves are connected to the wet joint. When the two bridge decks are joined, the pre-embedded grooves on both sides of the wet joint correspond one-to-one. Concrete can be integrally poured into the wet joint and the pre-embedded grooves during the wet joint pouring process. Simultaneously, shear reinforcement bars are embedded in the corresponding pre-embedded grooves on both sides to connect them, thereby ensuring the shear resistance of the wet joint. Furthermore, in the pre-... When constructing concrete bridge decks, the sidewalls of the embedded grooves are cast to form a corrugated wall. After the wet joint is poured, a corrugated construction joint is formed between the newly poured concrete and the sidewalls of the embedded groove. This ensures the tensile strength of the bridge decks on both sides. Furthermore, when the bridge decks are joined together, the distance between the two bridge decks can be reduced, which means reducing the width of the wet joint. This does not affect the mechanical properties of the wet joint of the bridge deck. Therefore, the amount of concrete poured into the wet joint can be greatly reduced, the curing time can be shortened, and the construction efficiency can be improved. Attached Figure Description

[0027] Example 1

[0028] This embodiment provides a bridge deck connection structure for forming narrow wet joints.

[0029] Figure 1 This is a top perspective view of the bridge deck connection structure for forming narrow wet joints according to the present invention. Figure 2 This is a side sectional view of the bridge deck connection structure for forming narrow wet joints according to the present invention.

[0030] like Figures 1 to 2 As shown in the figure, the bridge deck connection structure for forming a narrow wet joint described in this embodiment may include a wet joint 2 and multiple embedded grooves 3. The wet joint 2 is formed between the opposite end faces of two adjacent bridge decks 1. The embedded grooves 3 are spaced apart along the length of the wet joint 2 on the end faces of the bridge deck 1. The multiple embedded grooves 3 are correspondingly arranged on both sides of the wet joint 2 and communicate with the wet joint 2. Shear reinforcement 4 is connected between the two embedded grooves 3 correspondingly arranged on both sides of the wet joint 2. The sidewall of the embedded groove 3 is formed as a corrugated surface 31. Here, shear reinforcement 4 is used to form the narrow wet joint 2. The direction of the reinforcing bar 4 can be parallel to the surface of the bridge deck 1 and perpendicular to the wet joint 2. The two ends of the shear reinforcing bar 4 can be inserted into the pre-embedded grooves 3 on both sides of the wet joint 2. Concrete can be poured into the wet joint 2 in the pre-embedded grooves 3 at the same time, and the shear reinforcing bar 4 can be embedded in the concrete. The shear reinforcing bar 4 can connect the bridge deck 1 on both sides of the wet joint 2 through the newly poured concrete. The shear reinforcing bar 4 spanning across both sides of the wet joint 2 can improve the shear resistance of the wet joint 2, so as to avoid the weakening of its shear resistance after the width of the wet joint 2 is reduced.

[0031] This application involves creating multiple embedded grooves 3 side-by-side on the end faces of the bridge deck 1 on both sides of the wet joint 2, connecting the embedded grooves 3 to the wet joint 2. When the two bridge decks 1 are joined, the embedded grooves 3 on both sides of the wet joint 2 correspond one-to-one. Concrete can be integrally cast into the wet joint 2 and the embedded grooves 3 during the pouring of the wet joint 2. Simultaneously, shear reinforcement bars 4 are embedded in the corresponding embedded grooves 3 on both sides to connect them, thereby ensuring the shear resistance of the wet joint 2. Furthermore, during the precast concrete bridge deck 1, the sides of the embedded grooves 3... The corrugated wall surface is formed by pouring concrete into the wall. After the wet joint 2 is poured, a construction joint with a corrugated surface 31 is formed between the newly poured concrete and the side wall of the pre-embedded groove 3. This can ensure the tensile strength of the bridge deck 1 on both sides. On this basis, the distance between the two bridge deck 1 can be reduced when the bridge deck 1 is closed, which means reducing the width of the wet joint 2. At the same time, it will not affect the mechanical properties of the wet joint 2 of the bridge deck 1. Therefore, the amount of concrete poured into the wet joint 2 can be greatly reduced, the curing time can be reduced, and the construction efficiency can be improved.

[0032] Specifically, the shear reinforcement 4 can be embedded in the pre-embedded groove 3 and the wet joint 2 by layered pouring. That is, during pouring, a layer of concrete is first poured into the pre-embedded groove 3 and the wet joint 2 to the embedment height of the shear reinforcement 4, and then the lower radial part of the shear reinforcement 4 is embedded in the uncured concrete. Concrete is poured to completely form the pre-embedded groove 3 and the wet joint 2, so that the shear reinforcement 4 can be completely embedded in the preset position in the pre-embedded groove 3 and the wet joint 2.

[0033] In this embodiment, a corrugated plate is attached to the side wall of the embedded groove 3, and the corrugated plate is connected to the corrugated surface 31 of the side wall of the embedded groove 3. Here, the corrugated plate can be made of metal such as steel plate, or hard wood if the strength allows. When the bridge deck 1 is prefabricated, the corrugated plate can be installed in a preset position as a template. After the bridge deck 1 is cast as a whole, the embedded groove 3 will be naturally reserved at the corrugated plate. The side wall of the embedded groove 3 can be formed into a corrugated surface 31 structure that matches the surface of the corrugated plate. If the strength allows, the corrugated plate can be removed from the embedded groove 3 before pouring the wet joint 2 and the embedded groove 3, so that the newly poured concrete can directly contact the side wall of the embedded groove 3 to form a construction joint. Alternatively, in order to improve the strength, the corrugated plate can be left in the embedded groove 3 and the concrete can be poured directly to embed the corrugated plate in the embedded groove 3, so that the corrugated plate is located between the old and new concrete, which can further improve the tensile strength of the newly poured concrete in the embedded groove 3.

[0034] In this embodiment, multiple first reinforcing bars 5 are embedded in the bridge deck 1. These first reinforcing bars 5 are parallel to the surface of the bridge deck 1 and perpendicular to the wet joint 2. One end of each first reinforcing bar 5 extends into the pre-embedded groove 3 and connects with the shear reinforcement 4. Here, the first reinforcing bars 5 are reinforcing bars pre-embedded in the structure of the bridge deck 1 during prefabrication. The first reinforcing bars 5 can be correspondingly set with the pre-embedded grooves 3. That is, the opening position of the pre-embedded grooves 3 corresponds one-to-one with the position of the first reinforcing bars 5 on the end face of the bridge deck 1. One end of each first reinforcing bar 5 can pass through the groove wall of the pre-embedded groove 3. It extends into the pre-embedded groove 3 and can then be connected with the shear reinforcement 4. That is, when installing the shear reinforcement 4, a shear reinforcement 4 of appropriate size can be prepared before pouring, so that the length of the shear reinforcement 4 is equivalent to the spacing between the first reinforcement 5 corresponding to the bridge deck 1 on both sides. When installing the shear reinforcement 4, the two ends of the shear reinforcement 4 can be connected with the first reinforcement 5 on both sides firstly, or the first reinforcement 5 can be fixedly connected to the shear reinforcement 4 by welding as appropriate. The shear reinforcement 4 can be set up by the layered pouring method described above.

[0035] In addition, if the strength allows, the first reinforcing bar 5 and the shear reinforcing bar 4 can be set apart, that is, they are not connected and the shear reinforcing bar 4 directly bears the shear force for shear resistance. Of course, the overall shear resistance is better after the first reinforcing bar 5 and the shear reinforcing bar 4 are fixedly connected. The first reinforcing bar 5 and the shear reinforcing bar 4 can be connected when higher shear force is required. This utility model does not make a specific limitation on whether the first reinforcing bar 5 and the shear reinforcing bar 4 are connected.

[0036] In this embodiment, a second reinforcing bar 6 is placed at the bottom of the first reinforcing bar 5 and the bottom of the shear reinforcing bar 4 in the pre-embedded groove 3. The second reinforcing bar 6 is intersected with the first reinforcing bar 5 and the shear reinforcing bar 4. Here, the second reinforcing bar 6 is a reinforcing bar pre-embedded in the structure of the bridge deck 1 during the prefabrication of the bridge deck 1. Generally, the first reinforcing bar 5 and the second reinforcing bar 6 are arranged perpendicularly to each other. However, special or irregular bridge deck 1 structures are not excluded, in which case the first reinforcing bar 5 and the second reinforcing bar 6 are not arranged perpendicularly but intersecting. Multiple second reinforcing bars 6 are arranged throughout the bridge deck 1. The second reinforcing bars 6 are parallel to the surface of the bridge deck 1, and a pre-embedded groove is placed in the thickness direction of the bridge deck 1. For the part corresponding to 3, the second reinforcing bar 6 can be set at the bottom of the first reinforcing bar 5 and the bottom of the shear reinforcing bar 4. When setting the shear reinforcing bar 4, it can be directly erected on the second reinforcing bar 6. In the lower half of the bridge deck 1 in the thickness direction, that is, the part without the pre-embedded groove 3, the second reinforcing bar 6 is set on the first reinforcing bar 5. Of course, the relative positions of the second reinforcing bar 6, the first reinforcing bar 5 and the shear reinforcing bar 4 in the thickness direction of the bridge deck 1 can be arbitrarily selected according to the requirements, and the included angle between the first reinforcing bar 5 and the second reinforcing bar 6 can also be selected according to the actual situation. This utility model does not make specific limitations in this regard.

[0037] In this embodiment, the embedded groove 3 extends through the bridge deck 1 to the upper surface of the bridge deck 1 in the thickness direction. That is, the opening of the embedded groove 3 on the bridge deck 1 can be formed simultaneously on the end face and the upper surface of the bridge deck 1. This arrangement reduces the number of templates needed to form the embedded groove 3 during the prefabrication of the bridge deck 1. Only corrugated plates and bottom plates are needed to cast the embedded groove 3 structure. In addition, the embedded groove 3 with an opening on the upper surface of the bridge deck 1 facilitates the pouring of concrete for the wet joint 2. During pouring, concrete can be poured directly from the opening on the upper surface of the bridge deck 1. It also facilitates the installation of shear reinforcement 4 and the vibration of concrete in the embedded groove 3, thus better ensuring the pouring quality. Of course, the opening of the embedded groove 3 can also be formed only on the end face of the bridge deck 1. That is, the embedded groove 3 does not extend through the upper surface of the bridge deck 1 in the thickness direction. This utility model does not specifically limit the opening position of the embedded groove 3.

[0038] In this embodiment, the depth of the pre-embedded groove 3 in the thickness direction of the bridge deck 1 is 40% to 60% of the thickness of the bridge deck 1. Controlling the depth of the pre-embedded groove 3 within the range of 40% to 60% ensures that the upper first reinforcing bar 5 and the second reinforcing bar 6 can be located in the pre-embedded groove 3, and the lower first reinforcing bar 5 and the second reinforcing bar 6 can be completely embedded in the concrete of the bridge deck 1. This allows the bridge deck 1 structure below the pre-embedded groove 3 to maintain sufficient strength to withstand the pressure of the newly poured concrete in the pre-embedded groove 3. Of course, the depth of the pre-embedded groove 3 in the thickness direction of the bridge deck 1 can also be selected in any other way according to actual conditions, and is not limited to the range of 40% to 60% of the thickness of the bridge deck 1. This utility model does not make any specific limitation in this regard.

[0039] Example 2

[0040] This embodiment provides a bridge deck assembly.

[0041] The bridge deck assembly described in this embodiment includes a plurality of bridge decks 1 that are mated together, and a bridge deck connection structure for forming a narrow wet joint is provided between two adjacent bridge decks 1 as described in Embodiment 1.

[0042] In this embodiment, multiple shear keyways are provided on the bridge deck 1, and the shear keyways extend through the bridge deck 1 along its thickness direction. Here, multiple shear keyways can be arranged on the bridge deck 1. During the installation of the bridge deck 1, the shear keys on the steel beam 7 can be inserted into the shear keyways, and then concrete can be poured into the shear keyways to embed the shear keys in the bridge deck 1. The shear keys can be used to horizontally limit the bridge deck 1 and the steel beam 7, preventing the bridge deck 1 from being misaligned on the steel beam 7.

[0043] It should be noted that the bridge deck connection structure for forming narrow wet joints described in this embodiment is the same as the bridge deck connection structure for forming narrow wet joints described in Embodiment 1, and will not be described in detail in this embodiment.

[0044] Example 3

[0045] This embodiment provides a bridge.

[0046] The bridge described in this embodiment includes a steel beam 7 and the bridge deck assembly described in embodiment 2, with the bridge deck assembly mounted on the steel beam 7. Here, the steel beam 7 can also be replaced by other forms of beam structure such as a concrete box girder structure, and this utility model does not specifically limit it in this regard.

[0047] It should be noted that the bridge deck assembly described in this embodiment is the same as the bridge deck assembly described in Embodiment 2, and will not be described in detail here.

[0048] In summary, the bridge deck connection structure, bridge deck assembly, and bridge of this utility model for forming narrow wet joints can achieve this by creating multiple pre-embedded grooves side-by-side on the end faces of the bridge decks on both sides of the wet joint, connecting these grooves to the wet joint, and ensuring that the pre-embedded grooves on both sides of the wet joint correspond one-to-one when the two bridge decks are joined. Concrete can be integrally poured into the wet joint and the pre-embedded grooves during the wet joint pouring process. Simultaneously, shear reinforcement bars are embedded in the corresponding pre-embedded grooves on both sides to connect them, thereby ensuring the shear resistance of the wet joint. Furthermore... When precasting concrete bridge decks, the sidewalls of the embedded grooves are cast to form a corrugated wall. After the wet joint is poured, a corrugated construction joint is formed between the newly poured concrete and the sidewalls of the embedded groove. This ensures the tensile strength of the bridge decks on both sides. Furthermore, when the bridge decks are joined together, the distance between the two bridge decks can be reduced, which means reducing the width of the wet joint. At the same time, the mechanical properties of the wet joint of the bridge deck will not be affected. Therefore, the amount of concrete poured into the wet joint can be greatly reduced, the curing time can be shortened, and the construction efficiency can be improved.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
