Description

Technical Field

[0001] This application relates to the field of bridge wet joint construction technology, and in particular to a method for constructing embedded wet joint templates and an integrated machine for concrete paving and vibration reduction. Background Technology

[0002] In highway bridge construction, prestressed concrete beams are typically prefabricated in sections and then cantilevered to form large-span continuous beams. The gaps between the beams are connected and fixed using cast-in-place concrete, known as wet joints. Currently, full-span scaffolding is commonly used for wet joint construction on highway bridges. This involves erecting full-span scaffolding under the bridge, where workers install formwork, ensuring the two edges of the top surface of the formwork are flush with the bottom of the two beams at the wet joint. Then, workers erect formwork supports on the bridge deck. These supports consist of two perforated steel pipes spanning the two beams, which are locked to the formwork using bolts and screws. Reinforcing bars extending from the prefabricated beams to the wet joint are then tied with steel bars. Finally, concrete is poured, and after the concrete has set, the formwork and full-span scaffolding need to be removed.

[0003] However, this construction method has the following problems: 1. Traditional construction methods usually involve fixing the formwork first and then installing the reinforcing bars, which makes the formwork supports and bolts installed first hinder the installation of the reinforcing bars, reducing the efficiency and quality of the reinforcing bar binding; 2. The formwork supports are constructed using perforated steel pipes, and the formwork is locked by fixing the perforated steel pipes to the formwork tie rods. The strength and stability of the formwork supports are poor, and the stability of the formwork is also not high. Summary of the Invention

[0004] To improve the stability of the support structure, this application provides a method for constructing embedded wet joint formwork and an integrated machine for concrete paving and vibration reduction.

[0005] Firstly, This application provides a method for constructing embedded wet joint formwork, which employs the following technical solution: A method for constructing embedded wet joint formwork includes the following steps: Step 1: Erect scaffolding: Install and erect full-span scaffolding under the bridge, and lay working platforms along the length of the wet joints on the horizontal and vertical bars; Step 2, Binding Reinforcing Bars: Install reinforcing bars between the pre-embedded reinforcing bars of the two precast beams; Step 3: Install templates: Workers install templates along the length of the wet joint on the work platform. After the workers on the work platform align the templates horizontally and attach them tightly to the bottom of the precast beam, the workers on the bridge deck weld the upper end of the bolts to the pre-embedded steel bars on the precast beam for fixation. Step 4: Workers use a concrete paving and vibration damping machine to pour, vibrate, spread, and finish the concrete at the wet joints. Step 5: Concrete forming and curing; Step 6: Dismantle the formwork and scaffolding.

[0006] By adopting the above technical solution, the method of tying the reinforcing bars before installing the formwork not only facilitates the installation of reinforcing bars and improves the construction efficiency of reinforcing bar tying, but also eliminates the need to erect formwork supports for formwork fixation during formwork installation. Instead, a sturdy steel mesh can be laid first as an auxiliary support, and the bolts on the formwork can be directly welded and fixed to the reinforcing bars. This makes the formwork more stable and flat, reduces the cumbersome construction procedures of erecting and dismantling formwork supports and bolts, and avoids the impact of formwork supports on the efficiency and quality of reinforcing bar tying, effectively improving construction efficiency and quality.

[0007] Optionally, guardrails are installed on both sides of the scaffolding of the work platform, with safety nets hanging on the guardrails, and multiple diagonal braces are fixedly installed on the uprights; the formwork is made of plastic, and the width of the formwork is greater than the width of the wet joint.

[0008] By adopting the above-mentioned technical solutions, guardrails, safety nets, etc., the safety of the construction process has been improved, and the possibility of accidents has been reduced.

[0009] Secondly, This application also provides equipment applicable to the above-mentioned embedded wet joint template construction method. The equipment includes a machine body, a feeding cylinder fixed at the front end of the machine body, and a mixing component for mixing raw materials provided at the feeding cylinder. The mixing component includes a first connecting rod fixed to the machine body, a first connecting ring rotatably disposed on the first connecting rod, and a plurality of first mixing rods fixed on the side wall of the first connecting ring. The first mixing rods are arranged in an "L" shape.

[0010] By adopting the above technical solution, after the concrete is discharged from the discharge cylinder, the concrete can be mixed by the second mixing rod, which improves the uniformity of the concrete. At the same time, the equipment integrates pouring and mixing, which improves efficiency compared to manual operation.

[0011] Optionally, a first driving rod is rotatably mounted on the machine body, a first driving rack is rotatably mounted at the end of the first driving rod, a first driving gear is fixed at the top of the first connecting ring, the first driving rack meshes with the first driving gear, and a support plate is rotatably mounted on the first connecting rod. The support plate is C-shaped and the first driving rack passes through the support plate.

[0012] By adopting the above technical solution, the support plate simultaneously serves as a support and a limiting mechanism. The movement of the first driving rod drives the movement of the first driving rack, thereby causing the first connecting ring to rotate, which facilitates the stirring process of the first stirring rod.

[0013] Optionally, a second connecting ring is rotatably provided at the bottom of the first connecting rod, a support rod is fixed to the side wall of the first connecting rod, a transmission gear is rotatably provided on the side wall of the support rod, a bevel gear is fixed at the bottom of the first connecting ring and the top of the second connecting ring, the transmission gear meshes with the bevel gear, and a plurality of second stirring rods are fixed to the side wall of the second connecting ring, the second stirring rods being arranged in an "L" shape.

[0014] By adopting the above technical solution, the first connecting ring and the second connecting ring are driven by a transmission gear, so that the rotation directions of the first connecting ring and the second connecting ring are opposite. Therefore, the mixing directions of the first mixing rod and the second mixing rod are opposite, which can mix the concrete more evenly.

[0015] Optionally, a drive disc coaxial with the first drive rod is rotatably mounted on the machine body. A drive block is fixed to the end of the drive disc and the drive block contacts the end of the first drive rod. The bottom of the drive block is wavy. A first flat block is slidably mounted on the machine body. A starter rod is fixed on the first flat block and the starter rod abuts against the bottom end face of the drive disc.

[0016] By adopting the above technical solution, the first driving rod rotates during the rotation of the driving disk. Since the starting rod abuts against the bottom end face of the driving disk, the first flat block moves in the vertical direction through the starting rod during the rotation of the driving disk.

[0017] Optionally, a second leveling block is slidably disposed on the machine body, and a leveling rod is rotatably connected to the side wall of the second leveling block. The leveling rod is arranged in a "Z" shape. A leveling groove for engaging the leveling rod is opened on the side wall of the first leveling block. A control rod for pushing the leveling rod to rotate is slidably disposed on the machine body.

[0018] By adopting the above technical solution, the movement of the control rod can control whether the leveling rod is inserted into the leveling groove. In the initial state, the control rod and the leveling rod are in contact, and the leveling rod and the leveling groove are separated. The movement of the first leveling block will not drive the movement of the second leveling block. After the control rod moves away from the leveling rod, the end of the leveling rod is engaged in the leveling groove under the action of the torsion spring. At this time, the movement of the first leveling block drives the movement of the second leveling block, which facilitates the compaction of concrete and also plays a vibratory role. When the first leveling block and the second leveling block do not move synchronously, the second leveling block cannot play a vibratory role and only plays a paving role. When the two move synchronously, they have both of the above-mentioned functions.

[0019] Optionally, both the first stirring rod and the second stirring rod are rotatably connected to push plates at their ends, and the push plates are inclined.

[0020] By adopting the above technical solution, the pusher plate is set at an angle, which facilitates the mixing process and has a paving function, pushing the concrete toward the edge.

[0021] Optionally, an extension plate is rotatably connected to the machine body. The extension plate is inclined and an extension roller is rotatably connected to the end of the extension plate. A weight-adding plate is fixed on the extension plate. The weight-adding plate is C-shaped and several weight-adding blocks are detachably connected to the weight-adding plate.

[0022] By adopting the above technical solution and adjusting the number of weight blocks, the force exerted on the concrete by the extension plate and extension roller can be increased, which facilitates the concrete paving process.

[0023] In summary, this application includes at least one of the following beneficial technical effects of the embedded wet joint formwork construction method and the integrated concrete paving and vibration damping machine: 1. Adopting the method of tying the reinforcing bars first and then installing the formwork not only makes it easier for workers to install the reinforcing bars and improves the construction efficiency of reinforcing bar tying, but also eliminates the need to erect formwork supports for formwork fixation when installing the formwork. A sturdy steel mesh can be laid first as an auxiliary support, and the bolts on the formwork can be directly welded and fixed to the reinforcing bars. The formwork is more stable and flat, reducing the cumbersome construction procedures of building and dismantling formwork supports and bolts, avoiding the impact of formwork supports on the efficiency and quality of reinforcing bar tying, and effectively improving construction efficiency and construction quality. 2. After the concrete is discharged from the discharge cylinder, the concrete can be mixed by the second mixing rod to improve the uniformity of the concrete. At the same time, the equipment integrates pouring and mixing, which improves efficiency compared to manual operation. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] Firstly, This application discloses a construction method for embedded wet joint formwork. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 The construction method for embedded wet joint formwork includes the following steps: Step 1: Erect scaffolding: Install and erect multiple uprights, horizontal bars and vertical bars under the bridge, and connect them with couplers to form a full-span scaffolding. Scaffold boards are laid on the horizontal and vertical bars along the length of the wet joints to form a working platform. Step 2, Binding Reinforcing Bars: After cleaning the joints of the precast beams, install reinforcing bars between the embedded reinforcing bars of the two precast beams; Step 3: Install the template: Workers install the template along the length of the wet joint on the work platform. Two sets of steel pipe fittings are set on both sides of the bottom of the template, corresponding to the positions of the embedded steel bars of the precast beam. The steel pipe fittings include two steel pipes parallel to the length of the wet joint. Multiple screws are evenly spaced through the steel pipe fittings. The screws are passed through the space between the two steel pipes of the steel pipe fitting, the template and the embedded steel bars in sequence, so that the top of the screw does not exceed the top surface of the precast beam. Then, the screws are fixed to the template with U-shaped buckles and nuts. After the workers on the work platform align the template horizontally and stick it tightly to the bottom of the precast beam, the workers on the bridge deck weld the upper end of the screws to the embedded steel bars on the precast beam for fixation. Step 4: Pouring, vibrating, spreading, and finishing concrete at wet joints: Workers use a concrete spreading and vibration damping machine to pour, vibrate, spread, and finish concrete at the wet joints. Step 5, Concrete Forming and Curing: Cover the concrete with geotextile membrane and spray it with water for curing. Remove the geotextile membrane after the concrete has cured and formed. Step Six: Formwork and Scaffolding Removal: Workers remove the formwork below the wet joint by disassembling nuts, buckles, and steel pipes on the work platform, and cut off the threaded rods protruding from the concrete using a cutting machine. After all the formwork is removed, the entire full-span scaffolding is dismantled from top to bottom.

[0035] The working platform has guardrails on both sides of the scaffold planks, with safety nets hanging on them, and multiple diagonal braces fixed to the uprights. The formwork is made of plastic, and its width is greater than the width of the wet joint. This method facilitates construction under the bridge deck by erecting a full-span scaffold and setting up a working platform on it. The method of tying the reinforcing steel bars before installing the formwork not only allows workers to quickly install the steel bars but also provides auxiliary support for the formwork installation. After the bolts on the formwork are aligned, they are welded to the reinforcing steel bars to ensure the formwork is stably fixed to the bottom of the precast beam. After the formwork is installed, a concrete paving and vibration damping machine is used for concrete pouring, vibration, paving, and finishing, improving the concrete construction efficiency. This method improves efficiency, reduces labor intensity, and ensures the appearance quality of the bridge deck concrete. Finally, the formwork and scaffolding are dismantled on the work platform, and the collected formwork can be reused, reducing construction costs. Adopting a method of tying the reinforcing bars before installing the formwork not only facilitates worker installation and improves the efficiency of reinforcing bar tying, but also eliminates the need for formwork supports during installation. A sturdy steel mesh can be laid first as an auxiliary support, and the bolts on the formwork can be directly welded to the reinforcing bars for fixation. This results in more stable and flat formwork, reduces the cumbersome construction procedures of erecting and dismantling formwork supports and bolts, and avoids the impact of formwork supports on the efficiency and quality of reinforcing bar tying, effectively improving construction efficiency and quality.

[0036] Secondly, This application also discloses a device suitable for the above-mentioned embedded wet joint formwork construction method, referring to... Figure 5 , Figure 6 and Figure 7This equipment is the integrated concrete paving and vibration damping machine mentioned in step four. It includes a machine body 1, on which a drive wheel is rotatably mounted. The drive wheel is used to move the machine body 1 to the location where concrete needs to be poured. A discharge cylinder 2 is fixed to the front end of the machine body 1 by bolts. The discharge cylinder 2 is vertically arranged. A placement box for placing concrete is fixed to the top of the machine body 1 by bolts. The placement box is connected to the discharge cylinder 2. The concrete in the placement box can be poured to the location where concrete needs to be poured through the discharge cylinder 2. A mixing component is installed at the discharge cylinder 2. The mixing component is used to mix the concrete discharged from the discharge cylinder 2 to enhance the uniformity of the concrete.

[0037] Reference Figure 5 , Figure 6 and Figure 7 The mixing assembly includes a first connecting rod 3, which is vertically arranged and fixed to the machine body 1 by bolts. A first connecting ring 4 is sleeved on the side wall of the first connecting rod 3. The first connecting ring 4 is coaxially arranged with the first connecting rod 3 and can rotate on the first connecting rod 3. Several first mixing rods 5 are fixed to the side wall of the first connecting ring 4 by bolts. In this embodiment, there are four first mixing rods 5, which are evenly distributed around the axis of the first connecting ring 4. The first mixing rods 5 are L-shaped. One side of the first mixing rod 5 is horizontally arranged and fixed to the side wall of the first connecting ring 4, while the other side is vertically arranged and used to mix the concrete. After the concrete is discharged to the ground, the machine body 1 continues to move, and the first mixing rods 5 come into contact with the concrete and rotate, which makes the concrete more uniform.

[0038] Reference Figure 5 , Figure 6 and Figure 7A second connecting ring 10 is rotatably connected to the bottom of the first connecting rod 3. The second connecting ring 10 is coaxial with the first connecting rod 3 and can rotate on the first connecting rod 3. Two support rods 11 are integrally formed and fixed to the side wall of the first connecting rod 3. The axes of the two support rods 11 are horizontal, that is, the axis of the support rods 11 is perpendicular to the axis of the first connecting rod 3. A transmission gear 12 is rotatably connected to the side wall of the support rods 11. The transmission gear 12 is coaxial with the support rods 11. At the same time, bevel gears 13 are bolted to the bottom of the first connecting ring 4 and the top of the second connecting ring 10. The bevel gears 13 mesh with the transmission gears 12. Several second stirring rods 14 are bolted to the side wall of the second connecting ring 10. The second stirring rods 14 are L-shaped, and one side of the second stirring rod 14 is horizontally positioned. Fixed to the side wall of the second connecting ring 10, the other side rod is vertically arranged and used for mixing concrete. In this embodiment, there are four second mixing rods 14, and the second mixing rods 14 are evenly distributed around the axis of the second connecting ring 10. The rotation of the first connecting ring 4 drives the transmission gear 12 to rotate, and the rotation of the transmission gear 12 drives the second connecting ring 10 to rotate. The rotation directions of the first connecting ring 4 and the second connecting ring 10 are opposite. Therefore, the first mixing rod 5 and the second mixing rod 14 mix the concrete in different directions, which improves the uniformity of concrete mixing. At the same time, the ends of the first mixing rod 5 and the second mixing rod 14 are fixed with push plates 23 by bolts. The push plates 23 are inclined to facilitate the mixing process. The angle of the push plates 23 can be adjusted by adjusting the fixing angle of the bolts and the push plates 23, which also plays a role in spreading the concrete.

[0039] Reference Figure 5 , Figure 6 and Figure 7 A first driving rod 6 is rotatably mounted on the body 1. The length direction of the first driving rod 6 is parallel to the axis of the support rod 11. One end of the first driving rod 6 is rotatably connected to the body 1 via a rotating shaft, and the other end is rotatably mounted with a first driving rack 7 via a rotating shaft. A first driving gear 8 is fixed to the top of the first connecting ring 4 by bolts. The first driving rack 7 meshes with the first driving gear 8. A support plate 9 is rotatably mounted on the first connecting rod 3 via a rotating shaft. The support plate 9 is C-shaped, and the first driving rack 7 passes through the C-shaped support plate 9. In the space, the support plate 9 supports the first driving rack 7 and also limits its movement. The drive motor is fixed to the body 1 by bolts. The shaft of the drive motor is keyed to the shaft connecting the first driving rod 6 and the body 1. When the drive motor starts, it drives the first driving rod 6 to rotate. The rotation of the first driving rod 6 drives the first driving rack 7 to move. Under the limiting effect of the support plate 9, the first driving rack 7 drives the first driving gear 8 to rotate during its movement, which in turn drives the first connecting ring 4 to rotate. The operation process is relatively simple.

[0040] Reference Figure 5 , Figure 6 and Figure 7 A drive disc 15 is rotatably mounted on the machine body 1. The drive disc 15 is coaxially arranged with the first drive rod 6. A drive block 16 is integrally formed and fixed to the upper end face of the drive disc 15. The drive block 16 can contact the side wall of the end of the first drive rod 6. During the rotation of the first drive rod 6 and the first drive rack 7, the side wall of the end of the first drive rod 6 contacts the drive block 16 and drives the drive block 16 to rotate, that is, drives the drive disc 15 to rotate. The bottom of the drive disc 15 is wavy. A first flat block 17 is slidably mounted on the machine body 1. Two first sliding rods are fixed to the machine body 1 by bolts. Two first sliding rods are inserted through the first flat block 17, and a first spring is sleeved on the first sliding rod. The first spring is used to pull the first flat block 17 to move upward in the vertical direction. The first flat block 17 can slide in the vertical direction. At the same time, the top of the first flat block 17 is fixed with a starting rod 18 by integral molding. The starting rod 18 is vertically set and abuts against the end face of the bottom of the drive plate 15. A rolling ball is embedded at the end of the starting rod 18 and the rolling ball can rotate freely. During the rotation of the drive plate 15, the height of the first flat block 17 changes continuously with the different abutment positions of the starting rod 18.

[0041] Reference Figure 5 , Figure 6 and Figure 8 A second leveling block 19 is slidably mounted on the body 1. A first sliding rod passes through the second leveling block 19, allowing the second leveling block 19 to slide vertically on the first sliding rod without detaching from it. A leveling rod 20 is rotatably connected to the side wall of the second leveling block 19 via a pivot. The leveling rod 20 is Z-shaped. A leveling groove 21 is provided on the side wall of the first leveling block 17, through which the leveling rod 20 passes, engaging with the first leveling block 17. Thus, movement of the first leveling block 17 can drive movement of the second leveling block 19. A control rod 22 is slidably mounted on the body 1. The control rod 22 is vertically positioned and used to rotate the leveling rod 20. The pivot of the leveling rod 20 is equipped with... A torsion spring is provided to drive the end of the leveling rod 20 toward the leveling groove 21. In the initial state, the control rod 22 is in contact with the leveling rod 20, and the leveling rod 20 is separated from the leveling groove 21. The movement of the first leveling block 17 will not drive the movement of the second leveling block 19. After the control rod 22 moves away from the leveling rod 20, the end of the leveling rod 20 is engaged in the leveling groove 21 under the action of the torsion spring. At this time, the movement of the first leveling block 17 drives the movement of the second leveling block 19, which facilitates the compaction of concrete and also plays a vibratory role. When the first leveling block 17 and the second leveling block 19 do not move synchronously, the second leveling block 19 cannot play a vibratory role and only plays a paving role. When the two move synchronously, they have both of the above-mentioned functions.

[0042] Reference Figure 5 An extension plate 24 is rotatably connected to the machine body 1 via a rotating shaft. The extension plate 24 is inclined to facilitate the spreading of concrete. At the same time, an extension roller 25 is rotatably connected to the end of the extension plate 24 via a rotating shaft. The side wall of the extension roller 25 contacts the concrete, and it plays the role of spreading and smoothing. A weight-reinforcing plate 26 is fixed on the extension plate 24 in an integral molding manner. The weight-reinforcing plate 26 is "C" shaped, and several weight-reinforcing blocks 27 are detachably connected to the weight-reinforcing plate 26 by stacking. By changing the number of weight-reinforcing blocks 27, the pressure of the extension plate 24 and the extension roller 25 on the concrete can be increased, which facilitates the concrete laying process.

[0043] The implementation principle of the embedded wet joint formwork construction method and the integrated concrete paving and vibration damping machine in this application embodiment is as follows: A full-span scaffold is erected, and a working platform is set up on the scaffold to facilitate construction under the bridge deck. The method of tying the reinforcing bars before installing the formwork not only facilitates rapid installation of the reinforcing bars but also provides auxiliary support for the formwork installation. After the bolts on the formwork are aligned, they are welded and fixed to the reinforcing bars, ensuring the formwork is stably fixed at the bottom of the precast beam. After the formwork is installed, the integrated concrete paving and vibration damping machine is used for concrete pouring, vibration, paving, and finishing, improving concrete construction efficiency, reducing labor intensity, and ensuring the appearance quality of the bridge deck concrete. Finally, the formwork and scaffolding are dismantled on the working platform. The collected formwork can be reused, reducing construction costs.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
