Description

Technical Field

[0001] The present invention relates to the technical field of bridge isolation walls, and in particular to a prefabricated structure and method for a bridge isolation wall. Background Art

[0002] Bridge isolation walls are facilities used on both sides of highways, railways and urban traffic bridges to separate lanes and prevent vehicles from driving off the road. It not only has a protective function, but also can effectively reduce the impact force when an accident occurs and improve driving safety. At present, the production method of bridge isolation walls usually adopts mold casting technology, that is, concrete is cast into shape through prefabricated molds. However, there are some technical difficulties in the existing bridge isolation wall production process.

[0003] First, demoulding is a complex and time-consuming process after direct casting using a mold. Traditional methods usually require disassembling the mold to complete demoulding, a process that is not only time-consuming but also requires a lot of manpower to operate, which is inefficient. In addition, some construction units use equipment to flip the mold for demoulding, but this method requires expensive flipping equipment, resulting in high production costs. Especially in large-scale production, the equipment and labor costs required for mold disassembly and flipping further increase the overall production cost.

[0004] Therefore, with the increasing demand for construction efficiency and cost control, a new type of prefabricated structure of bridge isolation wall is proposed. Summary of the invention

[0005] The object of the present invention is to provide a prefabricated structure and method for a bridge isolation wall, which can effectively improve the production efficiency of the bridge isolation wall and reduce the construction cost.

[0006] In the first aspect, the embodiments of the present invention are implemented by the following technical solutions: A prefabricated bridge isolation wall structure, comprising: A box mold, wherein the top of the box mold is open and the top of the box mold is larger than the bottom; A flip frame, wherein a plurality of flip frames are arranged along the length direction of the box mold, and the flip frame comprises a flip plate and a connecting rod, wherein the flip plate is in an arc shape and is arranged on one side in the width direction of the box mold, and the arc protruding part of the flip plate is arranged away from the box mold, one end of the flip plate extends to the top of the box mold, and the other end extends to the bottom of the box mold, and the flip plate is fixedly connected to the box mold through the connecting rod; Support rods, the support rods are arranged on both sides of the box mold in the length direction, the support rods are slidably arranged on the box mold along the height direction of the box mold, and after the support rods slide a certain distance along the bottom end of the box mold, they can extend to the bottom end of the box mold with the flip plate to form a support surface, and the support surface is parallel to the ground; A locking piece is used to lock the position of the support rod after sliding.

[0007] Furthermore, all the flip plates are located at one side of the bottom end of the box mold and are commonly connected in series with a ground connecting rod, and a flip fillet is provided on one side of the bottom wall of the ground connecting rod close to the flip plate.

[0008] Furthermore, the locking piece includes a clamping rod, a sliding seat is fixedly provided at a position of the box mold close to the support rod, the clamping rod is slidably passed through the sliding seat, a clamping block is fixedly provided on the support rod, and the clamping rod can abut against the clamping block. At this time, the support rod and the flip plate extend to the bottom end of the box mold to form a supporting surface.

[0009] Furthermore, the support rod is arranged in a Z-shaped bend, and the two ends of the Z-shape are parallel and vertically arranged. The top of the box mold is integrally provided with a flange, and the top of the support rod is slidably passed through the middle position of the flange, and the bottom end of the support rod is located at the four corners of the box mold. A V-shaped spring plate is fixedly provided on one end of the support rod passing through the flange, and the tip of the V-shaped spring plate is arranged away from the box mold and is arranged along the width direction of the box mold as a whole, and the two ends of the V-shaped spring plate abut against the flange.

[0010] Furthermore, both ends of the V-shaped spring plate are rounded.

[0011] Furthermore, the flip plate has a raised portion on one side facing away from the box mold, and the raised portion is arranged close to the top end of the flip plate.

[0012] Furthermore, rubber pads are fixedly provided on the flange and the V-shaped spring plate.

[0013] Furthermore, the plurality of turnover frames are connected and fixed by reinforcing rods.

[0014] Furthermore, a plurality of ribs are fixedly welded to the outer wall of the box mold along the length direction, and the connecting rods are welded on the ribs.

[0015] In a second aspect, the embodiments of the present invention are implemented by the following technical solutions: A method for using a prefabricated structure of a bridge isolation wall, applicable to the prefabricated structure of the bridge isolation wall described in the above scheme, comprises the following steps: S1: Place the top opening of the box mold toward the top, and hoist and install the pre-tied steel bar structure into the box mold; S2: Pour concrete into the box form and perform curing within an appropriate period of time to ensure that the concrete is fully solidified; S3: Open the locking piece, the support rod will automatically slide upward under the pressure of the box mold, the box mold will flip along the arc surface of the flip plate under the action of gravity, and then a certain external force will be applied to the box mold to completely flip the bottom of the box mold to the top to achieve demoulding; S4: Carry out subsequent maintenance on the demoulding cement isolation wall to ensure that its strength and stability meet the requirements.

[0016] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: 1. The present invention places the top opening side of the box mold, which is larger at the top and smaller at the bottom, facing upward, which facilitates the overall lifting and installation of the pre-tied steel bar structure, simplifies the steel bar placement process, and improves construction efficiency. At the same time, since the center of gravity of the box mold is biased upward, it can cooperate with the flip plate under the action of gravity to automatically realize flip demoulding during the flip operation.

[0017] Specifically, after the concrete is poured inside the box mold and properly cured, the locking piece is opened, the support rod automatically slides upward under the pressure of the box mold, and the box mold flips along the arc surface of the flip plate under the action of gravity. After the external force is applied, the bottom of the box mold is completely flipped to the top, and the demoulding is completed smoothly. This process greatly simplifies the traditional demoulding steps, reduces manual intervention, and reduces the complexity and risk of operation.

[0018] In summary, the present invention not only improves the degree of automation of construction and reduces labor costs during construction by optimizing the box mold structure and flip demoulding method, but also effectively improves production efficiency and further reduces overall construction costs. In addition, the simplified demoulding process helps reduce losses and errors caused by improper operation, thereby ensuring the consistency of construction quality and finished products.

[0019] 2. The present invention provides a raised portion on the side of the flip plate away from the box mold. When the box mold flips along the arc surface of the flip plate, the design of the raised portion causes the box mold to bounce slightly under the action of gravity. This bouncing effect effectively reduces the friction between the box mold and the flip plate, thereby facilitating the demoulding process of the box mold. Due to the slight displacement caused by the bouncing, demoulding is smoother.

[0020] In addition, under the action of inertia, when a certain external force is applied to the box mold, the box mold will be easier to flip smoothly, reducing the difficulty of manual operation. Especially in the final stage of flipping, when the bottom of the box mold is completely flipped to the top, due to the effect of the convex part, the box mold will remain upright more stably, thus ensuring the stability and accuracy of demoulding.

[0021] Through this design, the present invention not only improves the demoulding efficiency, but also enhances the safety of operation, further simplifies the entire demoulding process, reduces labor intensity, and effectively improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0026] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4As shown, the present invention is a prefabricated structure of a bridge isolation wall, which includes a box mold 1, a turning frame 2, a support rod 3 and a locking piece 5. Through optimized structural design and reasonable coordination, it can simplify the production process of the bridge isolation wall, improve production efficiency, and ensure the safety and stability of construction operations.

[0027] Among them, the box mold 1 is the core component of the present invention, and its top is set as an open structure, and the opening at the top is larger than the bottom. This design is helpful for the placement and installation of the steel structure, and is convenient for better supporting and fixing the steel bars when pouring concrete in the box mold 1, and allows the concrete to be poured and cured uniformly. Since the top opening of the box mold 1 is larger than the bottom, this structure helps to avoid excessive compression of the box mold 1 and enhances the stability and strength of the box mold 1.

[0028] The flipping frame 2 is an important accessory of the box mold 1, and multiple flipping frames are arranged along the length direction of the box mold 1. Each flipping frame 2 includes a flipping plate 21 and a connecting rod 22. The flipping plate 21 adopts an arc-shaped design and is in a bent state. It is arranged on one side in the width direction of the box mold 1, and the arc-shaped protruding part of the flipping plate 21 is away from the box mold 1. This design allows the box mold 1 to be smoothly flipped along the arc-shaped surface of the flipping plate 21. One end of the flipping plate 21 extends to the top of the box mold 1, and the other end extends to the bottom of the box mold 1, ensuring that the box mold 1 can slide smoothly during the flipping process and can be flipped freely with the help of the curved structure of the flipping plate 21. The flipping direction Q of the box mold is as follows: Figure 3 As shown, the whole process reduces manual intervention, improves demoulding efficiency, and ensures the integrity and quality of the bridge isolation wall.

[0029] The support rods 3 are arranged on both sides along the length direction of the box mold 1, and the support rods 3 are slidably installed on the box mold 1 in the height direction of the box mold 1. Specifically, a plurality of sliding sleeves 14 are welded on the box mold 1, and the support rods 3 are slidably connected to the sliding sleeves 14. The design of the support rods 3 ensures the stability and controllability of the flipping operation. Specifically, after the support rods 3 slide a certain distance along the bottom end of the box mold 1, the support rods 3 will extend to the bottom end of the box mold 1 with the flip plate 21 to form a support surface 4. The support surface 4 is parallel to the ground, can effectively support the weight of the box mold 1 during the flipping process, and prevent instability when the box mold 1 flips.

[0030] The locking member 5 is used to lock the fixed position of the support rod 3 after sliding, ensuring that the support rod 3 remains stable during the flipping process and preventing the support rod 3 from accidentally sliding or shifting. The reliability and durability of the locking member 5 are directly related to the safety of the entire structure and play a vital role in the flipping operation.

[0031] Reference Figure 1 and Figure 3As shown, all the flip plates 21 are connected in series and welded with a ground connecting rod 211 on one side of the bottom end of the box mold 1. The ground connecting rod 211 is used to abut against the ground and is in the shape of a long strip and consistent with the length direction of the box mold 1. A flip fillet 2111 is provided on the side of the bottom wall of the ground connecting rod 21 close to the flip plate 21. The design of the flip fillet 2111 effectively reduces the friction between the box mold 1 and the flip plate 21 during the flipping process, reduces the resistance during flipping, and enables the box mold 1 to flip more smoothly along the arc surface of the flip plate 21 after the support rod 3 moves up. The existence of the flip fillet 2111 can promote the smooth sliding of the box mold 1, reduce the stuck phenomenon, and improve the flipping efficiency. In addition, the flip fillet 2111 also increases the stability of the flipping process, avoids the sharp angle contact between the bottom of the box mold 1 and the flip plate 21, prevents the situation of uneven or skewed flipping, and ensures that the entire flipping process is smoother. This design can effectively improve production efficiency, reduce friction loss, and enhance the stability of the flipping process.

[0032] Reference Figure 1 and Figure 2 As shown, the locking member 5 includes a clamping rod 51, which is a square rod. A slide 11 is fixedly provided at a position of the box mold 1 near the support rod 3, and a pair of supporting structures are provided on the slide 11 and are located on both sides of the support rod 3. The clamping rod 51 is slidably penetrated on a pair of slides 11 at the same time, and a clamping block 31 is fixedly welded on the support rod 3. The clamping block 31 is a square block. The clamping rod 51 can be closely abutted against the plane of the clamping block 31 to ensure that the contact between the clamping rod 51 and the clamping block 31 is more stable. In order to unlock the support rod 3 during the flipping process, the clamping rod 51 and the clamping block 31 are in a disengaged state at this time, so that the support rod 3 can slide freely and be disconnected from the flip plate 21.

[0033] A knocking block 511 is fixedly provided on the clamping rod 51, and by knocking with external force, the clamping rod 51 is helped to quickly disengage from the clamping block 31, so that the support rod 3 slides smoothly, ensuring that the box mold 1 can be smoothly flipped according to the predetermined flipping path. In addition, the fixing method of the slide seat 11 and other components can be selected by welding according to actual conditions, which can increase the firmness and stability of the structure and further optimize the overall flipping mechanism. Through this improved design, the matching accuracy of the clamping rod 51 and the clamping block 31 can be improved, ensuring the efficiency and stability of the flipping process, and avoiding the unsmooth flipping caused by improper locking.

[0034] Reference Figure 3 and Figure 4As shown, the support rod 3 is arranged in a Z-shaped bend, and the two ends of the Z-shaped bend are respectively arranged parallel and vertically. The top of the box mold 1 is integrally welded with a flange 12, and the top of the support rod 3 is slidably inserted in the middle of the flange 12, and the bottom of the support rod 3 is located at the four corners of the box mold 1. A V-shaped spring plate 6 is fixedly welded to one end of the support rod 3 that passes through the flange 12, and the tip of the V-shaped spring plate 6 is arranged away from the box mold 1, and the whole is arranged along the width direction of the box mold 1. The two ends of the V-shaped spring plate 6 abut against the flange 12 to form a supporting effect.

[0035] The V-shaped spring plate 6 can be made of a steel plate with a certain elasticity. The elasticity of this material enables the V-shaped spring plate 6 to play a better buffering role during the flipping process of the box mold 1. Due to the existence of the V-shaped spring plate 6, when the box mold 1 is completely flipped, the V-shaped spring plate 6 can play a buffering role to avoid the instability caused by the box mold 1 flipping too large or too fast, thereby preventing damage to the ground. At the same time, the V-shaped spring plate 6 can also effectively reset the support rod 3, prompting the support rod 3 to slide in the direction of the ground connecting rod 211, so that it is repositioned and extends to the end of the flip plate 21 to form a support surface 4 at the bottom of the box mold 1. In this way, the support rod 3 does not need to be reset manually, which simplifies the operation process. It is only necessary to insert the clamping rod 51 into the slide seat 11 so that the clamping rod 51 abuts against the clamping block 31, and quickly complete the locking and restore the support function. Through this design, the box mold 1 can continue to be used after flipping back to its original position, which greatly improves production efficiency, simplifies the operation steps, and ensures the high efficiency of the equipment and the stability of long-term use.

[0036] Reference Figure 2 and Figure 3 As shown, both ends of the V-shaped spring plate 6 are rounded, and this design can effectively reduce the friction and impact with other parts of the box mold 1 during the flipping process. The rounded shape helps to achieve a smoother contact, avoiding the impact force that may be caused by sharp angles, thereby reducing the vibration or component damage that may occur during the flipping process. The rounded transition curve design can not only reduce the contact pressure, but also effectively disperse the pressure concentration area, avoid excessive wear and damage, and improve the durability and reliability of the equipment.

[0037] At the same time, the rounded corner design also makes the cooperation between the V-shaped spring plate 6 and other parts in the flipping process of the box mold 1 smoother. Especially after the box mold 1 is flipped, the contact between the two ends of the V-shaped spring plate 6 and the flange 12 is more stable, which helps to smoothly reset the support rod 3. This design not only improves the safety of the flipping process, but also reduces friction by optimizing the contact interface, reduces energy consumption, and improves flipping efficiency.

[0038] Reference Figure 1 and Figure 2As shown, a protrusion 212 is welded on the side of the flip plate 21 facing away from the box mold 1. The protrusion 212 is located at the top of the flip plate 21 and is designed in a semicircular shape. The protrusion 212 is provided to play an auxiliary role in the process of flipping the box mold 1. Due to the presence of the protrusion 212, when the support rod 3 moves up and the box mold 1 begins to flip, the protrusion 212 can slightly contact the surface of the box mold 1, forming a certain bouncing effect. Through this bouncing, the protrusion 212 can help the box mold 1 to be more easily separated from the mold, reduce the mold sticking phenomenon caused by close fit, and thus simplify the demolding process.

[0039] At the same time, the semicircular design of the raised portion 212 has better structural stability, making the movement of the flip plate 21 smoother during the flipping process. The semicircular shape can effectively reduce friction during the flipping process, avoid unnecessary damage to the surface of the box mold 1 caused by sharp angles, and reduce stress concentration on the flip plate 21 and the box mold 1 during flipping, thereby extending the service life. Overall, the semicircular design of the raised portion 212 not only improves the demoulding efficiency, but also ensures the smoothness of the flipping process and the long-term durability of the equipment, which helps to improve production efficiency and reduce maintenance costs.

[0040] Reference Figure 3 and Figure 4 As shown, rubber pads 7 are fixedly arranged on the flange 12 and the V-shaped spring plate 6. The purpose of setting the rubber pads 7 is to further improve the stability and buffering capacity of the equipment and prevent friction from causing unnecessary damage to the structure. In particular, the rubber pads 7 on the flange 12 are located at the top positions on both sides in the width direction of the box mold 1. The rubber pads 7 at this position can form effective contact with other components such as the V-shaped spring plate 6, the flip plate 21, etc. during the flipping process of the box mold 1, providing additional buffering effect.

[0041] Since the rubber pad 7 has good elasticity and cushioning properties, it can effectively absorb the impact force and vibration generated during the flipping process, and prevent wear and damage caused by direct contact, especially in the stress concentration area generated during the flipping process. The rubber pad 7 at the top of the flange 12 can also ensure that the flip plate 21 is in contact with the box mold 1 more smoothly, reducing the noise and vibration generated during flipping, thereby improving the overall comfort and safety of the operation. In addition, the rubber pad 7 on the V-shaped spring plate 6 can also play a similar buffering and protective role when contacting the flange 12 or the ground.

[0042] Reference Figure 1 and Figure 3As shown, multiple flip frames 2 are connected and fixed by reinforcing rods 23. This design ensures the stability of the flip frame 2 and the firmness of the structure. Installing reinforcing rods 23 between multiple flip frames 2 helps to disperse and evenly bear the force during the flipping process, and prevents the flip frame 2 from deforming or displacing during the flipping process. Through the connection of reinforcing rods 23, the overall rigidity and load-bearing capacity of the flip frame 2 can be effectively improved, thereby enhancing the stability of the system, ensuring that the box mold 1 always maintains balance during the flipping process, and reducing the operational risks caused by structural instability.

[0043] In addition, refer to Figure 1 and Figure 2 As shown, the outer wall of the box mold 1 is fixedly welded with a plurality of ribs 13 along the length direction, and the connecting rods 22 are welded on the ribs 13. The provision of the ribs 13 not only increases the strength of the box mold 1, but also improves the overall structural stability of the box mold 1. The ribs 13 provide stronger support and deformation resistance by combining with the connecting rods 22. Especially under the action of gravity, the ribs 13 can effectively disperse the pressure applied from the outside to prevent the box mold 1 from excessive deformation or tilting. The welded connecting rods 22 enhance the fixing effect of the ribs 13 and the box mold 1, so that the box mold 1 always remains stable during the flipping process, avoiding the possibility of structural loosening or swaying, and improving the durability and safety of the equipment.

[0044] Through the design of the reinforcing rods 23 and the ribs 13, the entire box mold 1 structure is not only more solid, but also has a better force distribution capability during the flipping process, ensuring a smooth and efficient flipping process, and further improving the safety and efficiency of production.

[0045] In addition, the embodiments of the present invention are implemented by the following technical solutions: A method for using a prefabricated structure of a bridge isolation wall, applicable to the prefabricated structure of the bridge isolation wall in the above scheme, comprises the following steps: S1: Place the top opening side of the box mold 1 facing upward, and hoist and install the pre-tied steel bar structure as a whole into the box mold 1; S2: pouring concrete into the box form 1 and curing it within a suitable period of time to ensure that the concrete is fully solidified; S3: Open the locking piece 5, the support rod 3 will automatically slide upward under the pressure of the box mold 1, and the box mold 1 will flip along the arc surface of the flip plate 21 under the action of gravity, and then a certain external force will be applied to the box mold 1, so that the bottom of the box mold 1 will be completely flipped to the top, and demoulding will be achieved; S4: Carry out subsequent maintenance on the demoulding cement isolation wall to ensure that its strength and stability meet the requirements.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
