Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a bridge deck connection structure and construction method. Background Technology

[0002] Steel-concrete composite beam bridges refer to modern bridge types that fully utilize the mechanical properties of both steel and concrete. Their core design concept is to combine two steel beams with a concrete bridge deck into a whole structure that shares the load through reliable connectors.

[0003] Currently, existing bridge deck connections generally employ a wet joint construction method (connecting multiple bridge decks together by pouring concrete). This traditional method has several drawbacks: wet joint technology requires a series of complex procedures on-site. First, on-site formwork is necessary, requiring precise erection of templates based on the dimensions and joint shape of the precast bridge decks. This process is not only time-consuming and labor-intensive but also demands high precision in template installation; otherwise, the quality of subsequent concrete pouring will be affected. Furthermore, the quality of on-site construction is susceptible to various factors and fluctuates significantly. During rebar splicing or welding, variations in worker skill levels can lead to defects such as insufficient lap lengths and weak welds, reducing the load-bearing capacity of the rebar and impacting structural safety. During precast bridge deck erection, if the erection position deviates, the fixed position of the embedded rebars offers very limited room for adjustment. Significant deviations may necessitate readjusting the precast bridge deck positions or even rework, increasing construction difficulty and costs while further extending the construction period. Summary of the Invention

[0004] The purpose of this invention is to provide a bridge deck connection structure and construction method that effectively solves the technical problems of cumbersome procedures, poor reliability and low fault tolerance that exist when traditional bridge decks are connected by wet joints.

[0005] To achieve the above objectives, the present invention provides a bridge deck connection structure, comprising two adjacent and symmetrically arranged panel assemblies, an adjustment assembly, and a connecting assembly. Each panel assembly includes a bridge deck and anchorages. A fixing groove is formed on the upper surface of the bridge deck, and a first screw hole is formed on the bottom surface of the fixing groove. The anchorages are disposed within the fixing groove and fixedly connected to the bridge deck. Each anchorage has an upward-facing mounting groove. The adjustment assembly includes an adjustment member, the two ends of which can be inserted into the mounting grooves of the anchorages of the two adjacent panel assemblies to adjust the spacing between the two adjacent panel assemblies. The connecting assembly includes a bridging member, the two ends of which can be inserted into the mounting grooves of the anchorages of the two adjacent panel assemblies and fixedly connected to the anchorages of the two adjacent panel assemblies. After the spacing between the two adjacent panel assemblies is adjusted and determined by the adjustment member, the adjustment member is removed so that the two ends of the bridging member can be inserted into the mounting grooves of the anchorages of the two adjacent panel assemblies.

[0006] In one embodiment, the adjustment assembly further includes a first bolt. The adjustment member includes a first connecting portion and a first extension portion disposed on both sides of the first connecting portion. The first extension portion is inserted into the mounting groove through an opening. A second screw hole is provided on the upper surface of the first extension portion. The first bolt passes through the second screw hole of the first extension portion and the first screw hole of the fixing groove in sequence in the vertical direction to fix the adjustment member to the bridge deck.

[0007] In one embodiment, the mounting groove is cylindrical, and an inner wall surface of the mounting groove near a panel assembly has a first guide surface that slopes from top to bottom and away from another panel assembly. The outer wall of the first extension is provided with a second guide surface that abuts against the first guide surface.

[0008] In one embodiment, the adjustment assembly further includes a guide screw, which is vertically disposed on the sidewalls of two adjacent bridge decks. The adjustment component is sleeved on the outer periphery of the guide screw and slidably connected to the guide screw. A guide nut is screwed onto the outer wall of the guide screw, and the bottom end of the guide nut is connected to the top end of the adjustment component.

[0009] In one embodiment, the connecting assembly further includes a second bolt, and the bridging member includes a second connecting portion and a second extension portion disposed on both sides of the second connecting portion. The second extension portion is inserted into the mounting groove, and a third screw hole is provided on the upper surface of the second extension portion. The second bolt passes through the third screw hole of the second extension portion and the first screw hole of the fixing groove in sequence along the vertical direction to fix the bridging member to the bridge panel.

[0010] In one embodiment, a clearance hole is provided on the side of two adjacent anchors that are close to each other, and the adjusting member or bridging member is installed in the two adjacent anchors through the clearance hole.

[0011] In one embodiment, the panel assembly further includes multiple anchor bars that extend horizontally and are divided into two groups. The two groups of anchor bars are respectively fixed to the opposite sides of two anchors, and the multiple anchor bars in each group are arranged at intervals in the vertical direction.

[0012] In one embodiment, the connecting assembly further includes a sealing rubber strip disposed between two adjacent panel assemblies and abutting against one side of the bridge panel of each of the two adjacent panel assemblies.

[0013] On the other hand, based on the above-mentioned bridge deck connection structure, the present invention also provides a construction method, including the following steps: Step S1: Prefabricate the panel assembly and pre-embed anchors in the fixing grooves of two adjacent bridge panels; Step S2: Transport the prefabricated panel components to the construction site and erect them, and install the sealing rubber strips between two adjacent panel components; Step S3: Insert both ends of the adjusting component into the mounting grooves of the anchors of the two adjacent panel assemblies, fix the adjusting component to the bridge panel, and adjust the relative position of the two adjacent panel assemblies by tightening the first bolt. Step S4: After the relative positions of the two adjacent panel components are adjusted, remove the adjusting part from the mounting groove by turning the first bolt in the opposite direction, place the anchors of the two adjacent panel components at both ends of the bridging part into the mounting groove, and fix the bridging part to the bridge panel by turning the second bolt. Step S5: Pour non-shrink grout at the opening of the installation groove and at the joint of two adjacent bridge decks.

[0014] Compared with the prior art, the bridge deck connection structure and construction method of this invention have the following advantages: By adjusting the design of the components and connecting components, during construction, the adjusting parts are first embedded in the installation grooves of the anchors of adjacent panel components, which can drive the two adjacent bridge panels to extend horizontally and adjust the spacing between the two adjacent bridge panels. Unlike traditional wet joint connections, there is no need for complicated template installation, rebar tying, concrete pouring and curing. After the spacing is determined, the adjusting parts can be removed and the bridging parts can be installed to complete the connection, which greatly shortens the construction cycle, significantly improves construction efficiency and reduces construction costs. Traditional wet joint connections rely on the bonding strength of concrete and the anchoring effect of steel bars. During long-term use, the concrete is prone to cracking and spalling due to environmental factors and repeated vehicle loads, leading to a decrease in connection reliability. In contrast, this bridge deck connection structure uses bridging components to fix the connection to anchorages. The anchorages are firmly bonded to the bridge deck, and the bridging components are directly embedded in the installation grooves of the anchorages. This mechanical connection method is not affected by environmental factors and can provide stable and durable connection force, effectively ensuring the connection reliability between bridge decks and improving the overall structural safety of the bridge.

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] In the description of this invention, it should be understood that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to that other element. The terms "mounted," "connected," and "attached" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two elements or an interaction between two elements. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] In the description of this invention, it should be understood that the terms "height," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used in this invention to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0028] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] like Figures 1 to 9As shown, a preferred embodiment of the present invention provides a bridge deck connection structure, which includes two adjacent and symmetrically arranged deck assemblies 1, an adjustment assembly 2, and a connecting assembly 3. The deck assembly 1 includes a bridge deck 11 and an anchor 12. A fixing groove 111 is formed on the upper surface of the bridge deck 11, and a first screw hole 112 is formed on the bottom surface of the fixing groove 111. The anchor 12 is disposed in the fixing groove 111 and fixedly connected to the bridge deck 11. The anchor 12 has an upward-facing mounting groove 13. The adjustment assembly 2 includes an adjustment member 21, and the two ends of the adjustment member 21 are... The mounting groove 13 of the anchor 12 of two adjacent panel assemblies 1 can be inserted to adjust the spacing between the two adjacent panel assemblies 1; the connecting assembly 3 includes a bridging member 31, the two ends of which can be inserted into the mounting groove 13 of the anchor 12 of two adjacent panel assemblies 1 and are fixedly connected to the anchor 12 of the two adjacent panel assemblies 1; wherein, after the spacing between the two adjacent panel assemblies 1 is adjusted and determined by the adjusting member 21, the adjusting member 21 is removed so that the two ends of the bridging member 31 can be inserted into the mounting groove 13 of the anchor 12 of the two adjacent panel assemblies 1.

[0030] Based on the above technical features, this invention, by adjusting the design of component 2 and connecting component 3, allows for the following during construction: First, the adjusting component 21 is embedded into the mounting groove 13 of the anchor 12 of the adjacent panel component 1. This drives the two adjacent bridge panels 11 to extend horizontally, thereby adjusting the distance between them. Unlike traditional wet joint connections, this eliminates the need for complex procedures such as formwork installation, rebar tying, concrete pouring, and curing. Once the distance is determined, simply removing the adjusting component 21 and installing the connecting component 31 completes the connection. This significantly shortens the construction cycle, greatly improves construction efficiency, and reduces construction costs. Traditional wet joint connections rely on the bonding force of concrete and the anchoring effect of steel bars. During long-term use, the concrete is prone to cracking and spalling due to environmental factors and repeated vehicle loads, resulting in a decrease in connection reliability. In contrast, the connection structure of this bridge deck 11 is fixedly connected to the anchor 12 through the bridging component 31. The anchor 12 is firmly bonded to the bridge deck 11, and the bridging component 31 is directly embedded in the installation groove 13 of the anchor 12. This mechanical connection method is not affected by environmental factors and can provide stable and durable connection force, effectively ensuring the connection reliability between bridge decks 11 and improving the overall structural safety of the bridge.

[0031] As some embodiments of the present invention, such as Figures 3 to 5As shown, the adjustment assembly 2 also includes a first bolt 22. The adjustment member 21 includes a first connecting part 211 and a first extension part 212 disposed on both sides of the first connecting part 211. The first extension part 212 is inserted into the mounting groove 13 through an opening. A second screw hole 2121 is provided on the upper surface of the first extension part 212. The first bolt 22 passes through the second screw hole 2121 of the first extension part 212 and the first screw hole 112 of the fixing groove 111 in sequence along the vertical direction to fix the adjustment member 21 to the bridge deck 11. The adjusting component 21 is inserted into the mounting groove 13 of the anchor 12 through the first extension 212, achieving horizontal positioning and connection. The first bolt 22 passes through the second screw hole 2121 of the first extension 212 and the first screw hole 112 of the bridge deck 11 fixing groove 111 in the vertical direction, tightly fixing the adjusting component 21 to the bridge deck 11. This fixing method combining horizontal and vertical directions forms a multi-dimensional constraint, which greatly enhances the connection stability between the adjusting component 21 and the bridge deck 11, and ensures the accuracy of the adjusting component 21 in adjusting the spacing between adjacent bridge decks 11.

[0032] As some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the mounting groove 13 is cylindrical. An inner wall surface of the mounting groove 13 near one panel assembly 1 has a first guide surface 131 that slopes downwards and away from the other panel assembly 1. The outer wall of the first extension 212 has a second guide surface 213 that abuts against the first guide surface 131. Due to the inclined arrangement of the first guide surface 131, when the first extension 212 is inserted into the mounting groove 13 and the second guide surface 213 abuts against it, the first guide surface 131 exerts an inward pressing force on the second guide surface 213 in the horizontal direction, thereby firmly fixing the first extension 212 within the mounting groove 13. This horizontal constraint effectively prevents the adjusting member 21 from undergoing horizontal displacement due to external horizontal forces during use, enhancing the connection stability between the adjusting member 21 and the anchor 12, and thus ensuring the stability of the spacing between adjacent bridge deck panels 11.

[0033] As some embodiments of the present invention, such as Figures 3 to 4As shown, the adjustment assembly 2 also includes a guide screw 23, which is vertically disposed on the side wall of two adjacent bridge panels 11 that are close to each other. The adjustment member 21 is sleeved on the outer periphery of the guide screw 23 and is slidably connected to the guide screw 23. A guide nut 24 is screwed onto the outer wall of the guide screw 23, and the bottom end of the guide nut 24 is connected to the top end of the adjustment member 21. Through the design of the guide screw 23 and guide nut 24, the guide screw 23 is set vertically on the side wall of two adjacent bridge decks 11, providing a clear reference direction for the displacement of the adjusting member 21. When installing the adjusting member 21, by fitting it around the outer periphery of the guide screw 23, the adjusting member 21 can move along the vertical direction of the guide screw 23, avoiding vertical offset of the adjusting member 21 during installation, ensuring that the adjusting member 21 can be installed in the predetermined position, and improving the accuracy and precision of installation. By rotating the guide nut 24, since the bottom end of the guide nut 24 is connected to the top end of the adjusting member 21, rotating the guide nut 24 can drive the adjusting member 21 to make a small movement on the guide screw 23, realizing a small adjustment of the distance between adjacent bridge decks 11.

[0034] As some embodiments of the present invention, such as Figure 6 and Figure 9 As shown, the connecting assembly 3 also includes a second bolt 32. The bridging member 31 includes a second connecting portion 311 and second extension portions 312 disposed on both sides of the second connecting portion 311. The second extension portions 312 are inserted into the mounting groove 13. A third screw hole 3121 is provided on the upper surface of the second extension portion 312. The second bolt 32 passes through the third screw hole 3121 of the second extension portion 312 and the first screw hole 112 of the fixing groove 111 in a vertical direction to fix the bridging member 31 to the bridge panel 11. Through the design of the second connecting portion 311 and the second extension portion 312, the second extension portion 312 of the bridging member 31 is inserted into the mounting groove 13, achieving horizontal positioning and providing lateral constraint for the overall structure. The second bolt 32 passes vertically through the third screw hole 3121 of the second extension 312 and the first screw hole 112 of the fixing groove 111, tightly fixing the bridging component 31 to the bridge deck 11. This fixing method, which combines horizontal and vertical directions, forms a multi-dimensional constraint system, greatly enhancing the connection strength between the bridging component 31 and the bridge deck 11. It effectively prevents the bridging component 31 from loosening, shifting, or falling off due to various external forces during use, ensuring the overall stability of the bridge deck 11 connection structure.

[0035] As some embodiments of the present invention, such as Figure 7As shown, clearance holes are provided on the side of two adjacent anchors 12 that are close to each other. Adjusting components 21 or bridging components 31 are installed in the two adjacent anchors 12 through the clearance holes. With the design of the clearance holes, the adjusting components 21 or bridging components 31 can be directly inserted into the installation groove 13 of the anchor winch. This design greatly simplifies the installation process, reduces the time and labor costs required for installation, and improves construction efficiency.

[0036] As some embodiments of the present invention, such as Figures 4 to 6 As shown, the panel assembly 1 also includes multiple anchor bars 14. The anchor bars 14 extend horizontally and are divided into two groups. The two groups of anchor bars 14 are fixed to the opposite sides of the two anchors 12, and the multiple anchor bars 14 in each group are arranged at intervals in the vertical direction. By setting multiple anchor bars 14, the anchorage area between the anchors 12 and the bridge panel 11 is greatly increased. After the adjustment assembly 2 or the connecting assembly 3 is connected to the anchors 12, when it is subjected to upward tension or external force attempting to pull the structure out, the numerous anchor bars 14 firmly grip the plate of the bridge panel 11, ensuring that the adjustment assembly 2 or the connecting assembly 3 is stably connected under complex stress conditions and will not loosen or detach.

[0037] As some embodiments of the present invention, such as Figures 5 to 6 As shown, the connecting component 3 also includes a sealing rubber strip 4, which is disposed between two adjacent panel components 1 and abuts against the opposite side of the bridge deck 11 of the two adjacent panel components 1. The design of the sealing rubber strip 4 forms a reliable waterproof barrier, preventing rainwater from seeping into the bridge's internal structure through the lateral gaps of the bridge deck 11 during rainy weather. Simultaneously, the sealing rubber strip 4 provides a seal, facilitating the subsequent pouring of non-shrink grout at the joint of the two adjacent bridge decks 11, thus extending the bridge's service life.

[0038] As some embodiments of the present invention, such as Figure 1 As shown, there are multiple anchorages 12, which are spaced apart along the width direction of the bridge deck 11. The bridge deck 11 typically has a certain span in the width direction and may bear loads of different magnitudes and directions at different locations. The multiple anchorages 12 spaced apart along the width direction of the bridge deck 11 can provide reliable connection points at different locations according to the actual stress conditions of the bridge deck 11, avoid structural damage caused by local stress concentration, and extend the service life of the bridge deck 11.

[0039] On the other hand, based on the aforementioned bridge deck connection structure, such as Figures 1 to 6 As shown, the present invention also provides a construction method, comprising the following steps: Step S1: Prefabricate panel assembly 1 and pre-embed anchorages 12 in the fixing grooves 111 of two adjacent bridge decks 11. Pre-embedding the anchorages 12 in the fixing grooves 111 of the bridge decks 11 during the prefabrication of panel assembly 1 ensures the positional accuracy of the anchorages 12, making them strictly meet the design requirements. This pre-embedding method can be standardized in the factory, reducing the uncertainty and error of on-site construction, improving the quality and consistency of panel assembly 1 prefabrication, and laying the foundation for subsequent precise connection.

[0040] Step S2: Transport the prefabricated panel assembly 1 to the construction site and erect it, and install the sealing rubber strip 4 between two adjacent panel assemblies 1; after the production is completed, transport the panel assembly 1 to the construction site for erection, which reduces the time and workload of on-site construction and speeds up the construction progress.

[0041] Step S3: Insert both ends of the adjusting component 21 into the mounting grooves 13 of the anchors 12 of the two adjacent panel assemblies 1, fix the adjusting component 21 to the bridge panel 11, and adjust the relative position of the two adjacent panel assemblies 1 by turning the first bolt 22; by turning the first bolt 22, the movement distance and position of the adjusting component 21 can be controlled, thereby realizing the fine adjustment of the position of the two adjacent bridge panels 11, ensuring that the joint between the adjacent bridge panels 11 is flat and aligned, and improving the overall appearance quality and performance of the bridge.

[0042] Step S4: After the relative positions of the two adjacent panel components 1 are adjusted, the adjusting component 21 is removed from the mounting groove 13 by reverse screwing the first bolt 22. The two ends of the bridging component 31 are then placed in the mounting grooves 13 of the anchors 12 of the two adjacent panel components 1, and the bridging component 31 is fixed to the bridge panel 11 by screwing the second bolt 32. This achieves a smooth transition from the adjustment stage to the fixing stage. This step-by-step connection method ensures the flexibility of the bridge panel 11 position during the adjustment process and ensures the connection strength and stability of the bridging component 31 after it is fixed to the bridge panel 11.

[0043] Step S5: Pour non-shrink grout into the opening of the mounting groove 13 and the joint between two adjacent bridge decks 11. By pouring non-shrink grout, these critical parts are further sealed, forming a double waterproof protection with the sealing rubber strip 4, effectively preventing moisture from corroding the inside of the connecting component 3 and the panel component 1, and ensuring the safety of the bridge structure.

[0044] In summary, the bridge deck connection structure and construction method provided by this invention have the following advantages compared with the prior art: By adjusting the design of component 2 and connecting component 3, during construction, the adjusting component 21 is first embedded into the installation groove 13 of the anchor 12 of the adjacent panel component 1, which can drive the two adjacent bridge decks 11 to extend horizontally, thereby adjusting the distance between the two adjacent bridge decks 11. Unlike traditional wet joint connections, this eliminates the need for complex template installation, rebar tying, concrete pouring, and curing processes. After determining the distance, only the adjusting component 21 needs to be removed, and then the bridging component 31 needs to be installed to complete the connection, greatly shortening the construction cycle and significantly improving efficiency. This improves construction efficiency and reduces construction costs. Traditional wet joint connections rely on the bonding force of concrete and the anchoring effect of steel bars. During long-term use, the concrete is prone to cracking and spalling due to environmental factors and repeated vehicle loads, leading to a decrease in connection reliability. In contrast, the bridge deck 11 connection structure is fixedly connected to the anchor 12 through the bridging component 31. The anchor 12 is firmly bonded to the bridge deck 11, and the bridging component 31 is directly embedded in the installation groove 13 of the anchor 12. This mechanical connection method is not affected by environmental factors and can provide stable and durable connection force, effectively ensuring the connection reliability between the bridge decks 11 and improving the overall structural safety of the bridge.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
