Description

Technical Field

[0001] This application relates to the technical field of bridge construction, and in particular to a temporary treatment device and method for expansion joints before bridge deck paving. Background Technology

[0002] The bridge is composed of multiple box girders spliced ​​together, and these box girders are supported on the ground by piers. In order to reduce the impact of thermal expansion and contraction on the bridge itself, a certain gap is reserved between two adjacent box girders, and then corresponding expansion joints are installed to form expansion joints. After the box girders are installed, an asphalt layer needs to be laid on the upper surface of the box girders. The solidified asphalt layer forms the bridge deck on the surface of the box girders, and the bridge deck is used for vehicles and pedestrians.

[0003] In the existing technology, in order to make the asphalt layers on adjacent box girders on the same plane, an asphalt layer needs to be laid on the adjacent box girders. After the asphalt layer is laid, it will fill the gap between the two adjacent box girders. In order to facilitate the installation of expansion joints, after the asphalt layer has solidified, it needs to be cut with a cutting machine to ensure that the reserved gap between the two box girders is exposed. Then, the expansion joint is installed above the reserved gap, and finally an expansion joint is formed between the two adjacent box girders.

[0004] In the aforementioned technologies, before installing the expansion joint, in order to ensure that the bridge decks on two adjacent box girders are on the same plane, the reserved gaps need to be filled. After the asphalt layer is laid, a cutting machine is needed to cut the bridge deck to expose the reserved gaps before the expansion joints can be installed, which slows down the overall bridge construction progress. Summary of the Invention

[0005] In order to improve the construction progress of the entire bridge, this application provides a temporary treatment device and method for expansion joints before bridge deck paving.

[0006] First aspect

[0007] The temporary treatment device for expansion joints before bridge deck paving provided in this application adopts the following technical solution:

[0008] A temporary treatment device for expansion joints before bridge deck paving includes an installation plate and two sealing plates disposed on the installation plate. The two sealing plates are used to abut against the end faces of two adjacent box girders. The installation plate is provided with an adjustment component for adjusting the position of the sealing plates and making the two sealing plates abut against the end faces of the adjacent box girders. The installation plate is also provided with a fixing component for fixing the installation plate within a reserved gap.

[0009] By adopting the above technical solution, after the installation of two adjacent box girders is completed, the bridge deck needs to be paved. Before the bridge deck is paved, the mounting plate is directly fixed in the reserved gap by the fixing component. Then, the position of the two sealing plates is adjusted by the adjusting component so that the two sealing plates abut against the end faces of the two adjacent box girders respectively. At this time, when laying the asphalt layer on the bridge deck, the height of the asphalt layer on the sealing plate is directly observed. When the heights of the two adjacent asphalt layers on the sealing plate are the same, the bridge deck thickness is the same. This replaces the traditional construction method of laying first and then cutting, thereby improving the construction speed of the bridge.

[0010] Optionally, each of the sealing plates is provided with a measuring plate for detecting the thickness of the asphalt layer, and the sealing plate is provided with a control component for moving the measuring plate along the thickness direction of the asphalt layer.

[0011] By adopting the above technical solution, before paving the bridge deck, the position of the measuring plate is first adjusted by the control component so that the distance between the lower surface of the measuring plate and the upper surface of the box girder is the same as the thickness of the asphalt layer to be laid, thus making the asphalt layer laying more convenient.

[0012] Optionally, the fixing assembly includes two fixing plates slidably connected to the mounting plate, the two fixing plates being used to abut against the end faces of two adjacent box girders, and the adjusting assembly being used to drive the two fixing plates to move in opposite directions on the mounting plate.

[0013] By adopting the above technical solution, when fixing the mounting plate, the two fixing plates are moved directly by adjusting the component, so that the two fixing plates move in opposite directions and push the two fixing plates against the end faces of the two adjacent box girders, thereby fixing the position of the mounting plate.

[0014] Optionally, the adjustment assembly includes a first screw rotatably connected to the mounting plate and a push plate slidably connected to the mounting plate. The push plate is used to push two fixed plates to move in opposite directions. The first screw passes through the push plate and is threadedly connected to the push plate.

[0015] By adopting the above technical solution, when it is necessary to fix the mounting plate in the reserved gap, the first screw is directly rotated. The first screw drives the push plate to move. When the push rod moves, it pushes the fixing plate to move in the opposite direction. At this time, it is more convenient to drive the fixing plate to move.

[0016] Optionally, the adjustment assembly further includes a push cam, which is used to abut against the sealing plate and push the two sealing plates to slide on the mounting plate. A rotating rod is rotatably connected to the mounting plate, and a linkage assembly is provided on the rotating rod. The push cam is connected to the rotating rod through the linkage assembly.

[0017] By adopting the above technical solution, when the push cam is connected to the rotating rod through the linkage component, the rotating rod rotates, which drives the push cam to rotate. The push cam then pushes the sealing plate to move, making it more convenient to drive the sealing plate to move.

[0018] Optionally, the linkage component includes a linkage rod slidably connected to the rotating rod, the linkage rod sliding along the length direction of the mounting plate, a first linkage groove being provided on the first screw, and a second linkage groove being provided on the pushing cam;

[0019] When the linkage rod moves into the first linkage slot, the rotating rod drives the linkage rod and the first screw to rotate. When the linkage rod moves into the second linkage slot, the rotating rod rotates, driving the linkage rod and pushing the cam to rotate.

[0020] By adopting the above technical solution, before the bridge deck is laid, the mounting plate is first placed between the reserved gaps, and then the linkage rod is moved into the first linkage groove. At this time, the rotating rod is rotated, and the rotating rod drives the first screw to rotate. The first screw drives the push plate to move, and the push plate pushes the two fixed plates to move in opposite directions. When the two sealing plates need to move in opposite directions, the linkage rod is moved into the second linkage groove. At this time, the rotating rod is rotated, and the rotating rod drives the push cam to rotate. The push cam pushes the two sealing plates to move.

[0021] Optionally, the linkage assembly includes a second screw threaded through the rotating rod, the second screw also threaded through the linkage rod and threadedly connected to the linkage rod, the second screw being used to drive the linkage rod to move along the axial direction of the first screw.

[0022] By adopting the above technical solution, when adjusting the position of the linkage rod, the second screw is directly rotated, and the rotation of the second screw drives the linkage rod to move along the axis of the second screw, which makes it more convenient to adjust the position of the linkage rod.

[0023] Optionally, the mounting plate is provided with a return spring for bringing the two fixed plates closer together, and the two ends of the return spring are respectively fixed to the two fixed plates.

[0024] By adopting the above technical solution, after the asphalt layer has solidified, it is necessary to remove the mounting plate. At this time, the second screw drives the linkage rod to move into the first linkage groove. Then, the first screw is rotated in the opposite direction, and the first screw drives the push plate to move in the opposite direction, so that the push plate and the fixed plate are separated. At this time, the reset spring pulls the fixed plate to move into the mounting plate, which makes it easy to remove the mounting plate.

[0025] Optionally, the control assembly includes a mounting base slidably connected to the sealing plate and a control screw rotatably connected to the mounting base. The control screw passes through the measuring plate and is threadedly connected to the measuring plate.

[0026] By adopting the above technical solution, when it is necessary to adjust the position of the measuring plate, the control screw can be directly rotated, and the control screw will drive the measuring plate to move, thus making it more convenient to adjust the position of the measuring plate.

[0027] Second aspect

[0028] A method for temporary treatment of expansion joints before bridge deck paving includes the following steps:

[0029] S1: Place the mounting plate in the reserved gap between two adjacent box girders;

[0030] S2: Rotate the second screw, and the second screw will drive the linkage rod to move into the first linkage groove;

[0031] S3: The rotating rod rotates, driving the first screw, which in turn moves the push plate. The push plate then pushes the two fixed plates away from each other, causing them to abut against the end face of the box girder.

[0032] S4: Rotate the second screw in the opposite direction to move the linkage rod into the second linkage groove;

[0033] S5: The rotation of the rotating rod drives the rotation of the push cam, which in turn pushes the cam to move the two sealing plates, and then adjusts the position of the two measuring plates.

[0034] By adopting the above technical solution, firstly, the rotating rod drives the first screw to rotate, the first screw drives the push plate to move, the push plate pushes the fixed plate to move, so that the mounting plate is fixed between the two box girders. Then, the rotating rod drives the push cam to rotate, the push cam pushes the two sealing plates away from each other. Finally, the control screw is rotated, and the position of the measuring plate is adjusted by the control screw so that the distance between the lower surface of the measuring plate and the upper surface of the box girder is the thickness of the asphalt layer.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0042] First aspect

[0043] This application discloses a temporary treatment device for expansion joints before bridge deck paving. (Refer to...) Figure 1 A temporary treatment device for expansion joints before bridge deck paving includes an installation plate 1, which is set between the reserved gaps between two adjacent box girders 01. The installation plate 1 is provided with a fixing component 2, which is used to fix the installation plate 1 in the reserved gap. Two sealing plates 11 are slidably connected on the installation plate 1. The two sealing plates 11 are used to abut against the end faces of the two adjacent box girders 01. By setting the two sealing plates 11, multiple reserved gaps can be sealed to prevent the asphalt layer from entering the reserved gaps when the asphalt layer is paved.

[0044] Reference Figure 1 and Figure 2 The sealing plate 11 includes a horizontal plate 111 and a vertical plate 112. The vertical plate 112 and the horizontal plate 111 are arranged vertically and are integrally formed. The horizontal plate 111 is slidably connected to the mounting plate 1. The vertical plate 112 is arranged along the thickness (asphalt layer thickness) direction of the box girder 01, and the side of the vertical plate 112 away from the horizontal plate 111 is used to abut against the end face of the box girder 01.

[0045] Reference Figure 1 and Figure 2A measuring plate 12 is slidably connected to each sealing plate 11. The measuring plate 12 is fitted onto the sealing plate 11 and slides along the thickness (asphalt layer thickness) of the box girder 01. A control component 3 is detachably connected to the sealing plate 11. The control component 3 is used to adjust the position of the measuring plate 12 so that the distance between the lower surface of the measuring plate 12 and the upper surface of the box girder 01 is equal to the thickness of the asphalt layer. When paving the bridge deck, it is only necessary to ensure that the asphalt layer abuts against the lower surface of the measuring plate 12, thus ensuring that the asphalt layers on two adjacent box girders 01 are on the same plane. After the asphalt layer solidifies, the mounting plate 1 is removed from the reserved gap, and then an expansion joint is installed between the reserved gaps. A sealing plate 13 is fixedly installed at both ends of each measuring plate 12. The sealing plate 13 seals the gap between two adjacent sealing plates 11, preventing asphalt from entering the reserved gap during asphalt layer paving.

[0046] Reference Figure 1 and Figure 2 Since the box girder 01 has a certain width, in order to facilitate the installation of the mounting plate 1 and the sealing plate 11 in the reserved gap, the length of the mounting plate 1 is less than the width of the box girder 01. In this embodiment, four mounting plates 1 are arranged along the width direction of the box girder 01. A positioning groove 14 is opened on the upper surface of the measuring plate 12. A positioning piece 15 is fixedly installed on the opposite side of the positioning groove 14. After the mounting plate 1 at the edge is fixed and the position of the measuring plate 12 is adjusted by the control component 3, when installing the adjacent mounting plates 1 and the position of the measuring plate 12, the positioning piece 15 on the adjacent measuring plate 12 is directly inserted into the positioning groove 14 on the adjusted measuring plate 12. At this time, the two adjacent measuring plates 12 are on the same plane, and the positions of multiple measuring plates 12 can be adjusted by one adjustment component 4. Thus, the control component 3 can be installed only on the mounting plate 1 at the outermost edge, thereby achieving the purpose of saving resources. Since each mounting plate 1 needs to be fixed in position, each mounting plate 1 is equipped with a fixing component 2, which fixes multiple mounting plates 1 to the box girder 01.

[0047] Reference Figure 2The control component 3 includes a mounting base 31 and a control screw 32. A limiting block 16 is fixedly mounted on the mounting base 31, and a limiting groove 17 is formed on the sealing plate 11. The cross-sections of both the limiting block 16 and the limiting groove 17 are T-shaped, and the end of the limiting groove 17 away from the mounting plate 1 is connected to the outside, making it easy to insert the limiting block 16 into the limiting groove 17. The limiting groove 17 is made of elastic rubber material. When the limiting block 16 is in the limiting groove 17, the limiting block 16 is in a compressed state, and the mounting base 3... The position of the measuring plate 12 is fixed, and the control screw 32 is rotatably connected to the mounting base 31. The measuring plate 12 has a threaded hole, and the control screw 32 is used to pass through the threaded hole. The control screw 32 is threadedly connected to the measuring plate 12 through the threaded hole. When it is necessary to adjust the position of the measuring plate 12, the mounting base 31 can be fixed on the sealing plate 11 first, then the control screw 32 can be threadedly connected to the measuring plate 12, and finally the control screw 32 can be rotated to drive the measuring plate 12 to slide on the sealing plate 11, which makes it more convenient to use.

[0048] Reference Figure 3 and Figure 4 An adjustment component 4 is provided on the mounting plate 1. The adjustment component 4 is used to adjust the position of the sealing plate 11 on the box girder 01 so that both sealing plates 11 abut against the split end face of the box girder 01. At the same time, a linkage component 5 is provided on the adjustment component 4. Under the action of the linkage component 5, the adjustment component 4 can drive the sealing plate 11 to move, and can also drive the fixing component 2 to work.

[0049] Reference Figure 3 and Figure 4 The fixing component 2 includes two fixing plates 21, both of which are slidably connected to the mounting plate 1. The sliding direction of the two fixing plates 21 is the same as the sliding direction of the two sealing plates 11. The adjusting component 4 includes a first screw 41 rotatably connected to the mounting plate 1 and a push plate 42 slidably connected to the mounting plate 1. The sliding direction of the push plate 42 is perpendicular to the moving direction of the fixing plates 21. The first screw 41 passes through the push plate 42 and is threadedly connected to the push plate 42. A push surface is provided on the push plate 42, and the fixing plates 21 abut against the push surface. Furthermore, the pushing member gradually tilts away from the vertical plate 112 in the direction close to the first screw 41, so that the cross section of the pushing plate 42 in the vertical direction gradually increases in the direction close to the first screw 41. Since two fixed plates 21 are provided, two pushing surfaces are also provided. Thus, when the fixed plate 21 is pushed to move, the first screw 41 is directly rotated. The first screw 41 drives the pushing plate 42 to move on the mounting plate 1. The pushing plate 42 pushes the two fixed plates 21 to move in opposite directions, so that the two fixed plates 21 abut against the end face of the box girder 01, thereby fixing the position of the mounting plate 1.

[0050] Reference Figure 3 and Figure 4 A reset spring 6 is provided on the mounting plate 1. The two ends of the reset spring 6 are fixed to two fixing plates 21 respectively. When the two fixing plates 21 are far apart, the reset spring 6 is in a stretched state. When it is necessary to remove the mounting plate 1 from the reserved gap, the first screw 41 is rotated in the opposite direction. At this time, the push plate 42 gradually moves away from the fixing plate 21, and the reset spring 6 pulls the two fixing plates 21 closer to each other.

[0051] Reference Figure 3 and Figure 4 The adjustment component 4 also includes a push cam 43 and a rotating sleeve 44 fixed on the push cam 43. The rotating sleeve 44 is rotatably connected to the mounting plate 1. The push cam 43 is provided with two protrusions. When the push cam 43 is rotated, it can drive the two sealing plates 11 to move away from each other at the same time, and finally push the two vertical plates 112 to abut against the end face of the box girder 01.

[0052] Reference Figure 4 and Figure 5 A rotating rod 61 is rotatably connected to the mounting plate 1. One end of the rotating rod 61 extends out of the surface of the mounting plate 1. The rotating rod 61 is connected to the first screw 41 via a linkage assembly 5. When the rotating rod 61 rotates, it can drive the first screw 41 to rotate. The linkage assembly 5 includes a linkage rod 51 and a second screw 52. The linkage rod 51 is arranged along the axial direction of the first screw 41, and the horizontal cross-section of the linkage rod 51 is polygonal. In this embodiment, the cross-section of the linkage rod 51 is set as hexagonal. The linkage rod 51 includes a linkage part 511 and a moving part 512. 1. The moving part 512 is integrally formed and the side length of the linkage part 511 is greater than the side length of the moving part 512. The moving part 512 is slidably connected to the rotating rod 61 along the axial direction of the rotating rod 61. The second screw 52 is rotatably connected to the rotating rod 61 and is sequentially passed through the moving part 512 and the linkage part 511. The second screw 52 is threadedly connected to the moving part 512 and the linkage part 511. When the second screw 52 is rotated, the second screw 52 can drive the moving part 512 and the linkage part 511 to move along the axial direction of the first screw 41.

[0053] Reference Figure 4 and Figure 5A first linkage groove 7 is provided on the first screw 41, and a second linkage groove 71 is provided on the rotating sleeve 44. The cross-sections of the second linkage groove 71 and the first linkage groove 7 are the same, and both are the same as the cross-section of the linkage part 511. When the second screw 52 drives the linkage part 511 to move into the first linkage groove 7, the moving part 512 is simultaneously located in the second linkage groove 71 and the rotating rod 61. At this time, the rotating rod 61 rotates, driving the linkage rod 51 to rotate. Then, the linkage rod 51 drives the first screw 41 to rotate, which in turn drives the push plate 42 to move. When the second screw 52 drives the linkage part 511 to move into the second linkage groove 71, the rotating rod 61 rotates, driving the linkage rod 51, the rotating sleeve 44, and the push cam 43 to rotate. At this time, the first screw 41 will not rotate, thereby allowing the position of the sealing plate 11 to be adjusted.

[0054] The implementation principle of the temporary treatment device for expansion joints before bridge deck paving in this application embodiment is as follows: Before laying the asphalt layer of the bridge deck, the mounting plate 1 is first placed in the gap between two adjacent box girders 01. Then, the second screw 52 is rotated, causing the second screw 52 to drive the linkage rod 51 to move into the first linkage groove 7. Then, the rotating rod 61 rotates, causing the first screw 41 to rotate. The first screw 41 drives the push plate 42 to move. The push plate 42 pushes the two fixed plates 21 away from each other and finally abuts against the end face of the box girder 01. Then, the second screw 52 is rotated in the opposite direction, causing the second screw 52 to drive the linkage rod 51 to move into the second linkage groove 71. Then, the rotating rod 61 rotates, causing the push cam 43 to rotate, causing the push cam 43 to push the two sealing plates 11 away from each other and abut against the end face of the box girder 01.

[0055] Finally, the position of the measuring plate 12 is adjusted by controlling the screw 32 so that the distance between the lower surface of the measuring plate 12 and the upper surface of the box girder 01 is equal to the thickness of the asphalt layer. Then, the two measuring plates 12 on the same mounting plate 1 are made to be at the same height. Finally, multiple mounting plates 1 are set along the width direction of the box girder 01 so that the positioning plates on adjacent measuring plates 12 are engaged in the positioning groove 14, thereby making multiple measuring plates 12 at the same height. Finally, an asphalt layer is laid on the surface of the box girder 01 to ensure that the asphalt layer is at the same height. After the asphalt layer solidifies, the mounting plate 1 is removed, and then the expansion joint is installed in the reserved gap to finally form an expansion joint, thereby replacing the traditional construction method and improving the construction speed of the bridge.

[0058] S1: Place the mounting plate 1 in the reserved gap between two adjacent box girders 01;

[0059] S2: Rotate the second screw 52, ​​and the second screw 52 will drive the linkage rod 51 to move into the first linkage groove 7;

[0060] S3: Rotating rod 61 rotates to drive first screw 41, first screw 41 drives push plate 42 to move, push plate 42 pushes two fixed plates 21 away from each other, so that the two fixed plates 21 abut against the end face of box girder 01;

[0061] S4: Rotate the second screw 52 in the opposite direction so that the second screw 52 drives the linkage rod 51 to move into the second linkage groove 71;

[0062] S5: Rotating rod 61 drives cam 43 to rotate, which in turn drives cam 43 to move the two sealing plates 11, and then adjusts the position of the two measuring plates 12.

[0063] The implementation principle of the temporary treatment method for expansion joints before bridge deck paving in this application embodiment is as follows: First, the first screw 41 is rotated by the rotating rod 61, the first screw 41 moves the push plate 42, the push plate 42 moves the fixed plate 21, so that the mounting plate 1 is fixed between the two box girders 01. Then, the push cam 43 is rotated by the rotating rod 61, the push cam 43 pushes the two sealing plates 11 away from each other. Finally, the control screw 32 is rotated, and the position of the measuring plate 12 is adjusted by the control screw 32. At this time, the distance between the lower surface of the measuring plate 12 and the upper surface of the box girder 01 is the thickness of the asphalt layer.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.

The cross-section of the linkage rod (51) is hexagonal, and the linkage rod (51) includes a linkage part (511) and a moving part (512). The linkage part (511) and the moving part (512) are integrally formed, and the side length of the linkage part (511) is greater than the side length of the moving part (512). The moving part (512) is slidably connected to the rotating rod (61) along the axial direction of the rotating rod (61). The second screw (52) is rotatably connected to the rotating rod (61), and the second screw (52) is sequentially passed through the moving part (512) and the linkage part (511). The second screw (52), the moving part (512), and the linkage part (511) are threadedly connected. When the second screw (52) is rotated, the second screw (52) can drive the moving part (512) and the linkage part (511) to move along the axial direction of the first screw (41). The second linkage groove (71) and the first linkage groove (7) have the same cross-section, and both have the same cross-section as the linkage part (511). When the second screw (52) drives the linkage part (511) to move into the first linkage groove (7), the moving part (512) is simultaneously in the second linkage groove (71) and the rotating rod (61). At this time, the rotating rod (61) rotates and drives the linkage rod (51) to rotate. Then the linkage rod (51) drives the first screw (41) to rotate, and the first screw (41) drives the push plate (42) to move. When the second screw (52) drives the linkage part (511) to move into the second linkage groove (71), the rotating rod (61) rotates and drives the linkage rod (51), the rotating sleeve (44) and the push cam (43) to rotate. At this time, the first screw (41) will not rotate, and the position of the sealing plate (11) can be adjusted.
