Description

Technical Field

[0001] This utility model relates to the field of bridge crash barrier construction technology, and in particular to a bridge crash barrier formwork construction device. Background Technology

[0002] Bridge crash barriers are an important component of bridges, primarily used to prevent vehicles from veering off the bridge deck in the event of an accident, thus preventing greater damage and casualties. They are typically constructed of reinforced concrete, offering high strength and durability. Common forms include vertical, inclined, and curved types, with the appropriate shape chosen based on the bridge's design and operational requirements. The height is generally determined by factors such as the bridge's height, traffic flow, and vehicle type, typically ranging from 0.8 meters to 1.2 meters. During the pouring and construction of bridge crash barriers, formwork must be installed on both the inner and outer sides.

[0003] Existing technologies, such as a utility model of a bridge crash barrier formwork support and positioning device (authorization announcement number CN218667174U), eliminate the need for workers to use suspended platforms for installation, simplifying the construction process, making operation simpler and construction more convenient, and improving the efficiency of bridge crash barrier formwork assembly and disassembly.

[0004] Currently, there is a lack of a formwork construction device that facilitates the movement of bridge crash barrier formwork and allows for adjustments as needed to accommodate the pouring of crash barriers in the middle of bridges.

[0005] Therefore, in order to address the above problems, a bridge crash barrier formwork construction device is proposed to solve these problems. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by developing a bridge crash barrier formwork construction device. This device enables the formwork to move on the bridge deck and adjusts the formwork spacing according to the required width of the crash barrier, thus adapting to the pouring of crash barriers in the middle of the bridge.

[0007] The technical solution to the technical problem solved by this utility model is as follows: This utility model provides a bridge crash barrier formwork construction device, comprising: a first formwork connected to a set of evenly distributed positioning holes; a second formwork matched with the first formwork, the first formwork and the second formwork forming a pouring area; two sets of symmetrical mounting blocks, one set of mounting blocks being fixedly connected to the first formwork, and the other set of symmetrical mounting blocks being fixedly connected to the second formwork; a set of guide rods passing through the corresponding mounting blocks to provide guidance, allowing the first formwork and the second formwork to move along the direction of the guide rods and adjust the spacing; and an I-beam frame connecting the guide rods to provide support and guidance, thereby providing a stable and reliable support and positioning foundation for the construction of the bridge crash barrier formwork, and connecting the set of guide rods.

[0008] As an optimization, the I-beam frame is connected to an adjusting hydraulic rod, the piston rod of which is connected to a mounting base. The mounting base is rotatably connected to symmetrical adjusting rods, which in turn are rotatably connected to corresponding mounting blocks. By adjusting the extension and retraction of the hydraulic rod, the mounting base and adjusting rods are moved, thereby adjusting the position of the mounting blocks, which in turn allows for adjustment of the spacing between the first and second templates. This allows for flexible changes in the template spacing according to the actual dimensions and construction requirements of the bridge crash barrier, improving the adaptability and versatility of the template construction device, making it suitable for crash barrier construction of different widths.

[0009] As an optimization, the I-beam frame is connected to a lifting hydraulic rod, the piston rod of which is connected to a bracket. Four vertical rods of the bracket pass through the I-beam frame and are connected to wheel mounting seats, allowing the entire formwork construction device to be moved by wheels. This enables the device to be easily moved to different construction positions on the bridge, improving construction flexibility and efficiency, and reducing the workload and time spent manually handling formwork. This advantage is particularly pronounced when the bridge is long or the construction locations are dispersed. When the lifting hydraulic rod retracts, it brings the first and second formwork into contact with the bridge deck, facilitating construction.

[0010] As an optimization, the I-beam frame is connected to a set of guide cylinders, and the four vertical rods of the support are respectively set in the corresponding guide cylinders. When the lifting hydraulic rod drives the support to move up and down, the guide cylinders can guide and limit the vertical rods of the support, ensuring that the vertical rods of the support remain vertical and stable during the movement, avoiding tilting or swaying of the support during the movement, thereby improving the stability and reliability of the formwork construction device during the movement.

[0011] As an optimization, a set of guide rods passes through the fixed seat and the movable seat respectively. Each fixed seat is connected to a corresponding guide rod, and each fixed seat is rotatably connected to a support rod. Each support rod contacts a corresponding second template. Each movable seat is rotatably connected to a Y-rod, and each Y-rod is rotatably connected to a corresponding support rod. The support rods provide auxiliary support for the second template, better adapting to stress changes during construction.

[0012] As an optimization, each of the movable seats is threadedly connected with a bolt, and each of the guide rods is provided with a set of positioning holes, with the bolts matching the positioning holes. Through the cooperation of the bolts and positioning holes, the movable seat can be fixed at a specific position on the guide rod, thereby ensuring the stability of the support rod.

[0013] As an optimization, each of the fixed seats is connected to one end of a spring, and each spring is looped around the corresponding guide rod. The other end of each spring is connected to the corresponding movable seat. The elasticity of the springs ensures that the support rod remains in contact with the second template at all times.

[0014] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0015] (1) This device, with the help of an adjustment mechanism consisting of an adjusting hydraulic rod, a mounting base, and an adjusting connecting rod, can easily adjust the distance between the first template and the second template. This allows the construction device to adapt to the construction needs of bridge crash barriers of different widths, improving the versatility and applicability of the device.

[0016] (2) This device achieves convenient movement of the entire formwork construction device through the coordinated action of components such as lifting hydraulic rods, supports, wheels, and guide cylinders. During bridge construction, the device can be quickly moved to different construction positions as needed, eliminating the need for manual handling and greatly improving construction efficiency.

[0017] (3) This device uses the cooperation of bolts and positioning holes on the guide rod to fix the movable seat in a specific position, thereby locking the support rod. This ensures the stability of the formwork support during construction, prevents the support rod from loosening or shifting due to accidental vibration or external force, and ensures the pouring quality of the crash barrier.

[0025] like Figures 1 to 4As shown in Embodiment 1: A bridge crash barrier formwork construction device includes: a first formwork 6 connected to a set of evenly distributed positioning hole plates 7; a second formwork 8 matched with the first formwork 6, the first formwork 6 and the second formwork 8 forming a pouring area; two sets of symmetrical mounting blocks 9, one set of mounting blocks 9 being fixedly connected to the first formwork 6, and the other set of symmetrical mounting blocks 9 being fixedly connected to the second formwork 8; a set of guide rods 5 passing through the corresponding mounting blocks 9, serving as guides, allowing the first formwork 6 and the second formwork 8 to move along the direction of the guide rods 5, thus adjusting the spacing; and an I-beam 2 connected to the guide rods 5, serving as support and guide, thereby providing a stable and reliable support and positioning foundation for the construction of the bridge crash barrier formwork, connecting the set of guide rods 5.

[0026] like Figure 1-3 As shown, the I-beam frame 2 is connected to an adjusting hydraulic rod 11. The piston rod of the adjusting hydraulic rod 11 is connected to a mounting base 12. The mounting base 12 is rotatably connected to symmetrical adjusting connecting rods 13. The symmetrical adjusting connecting rods 13 are rotatably connected to the corresponding mounting blocks 9. By adjusting the extension and retraction of the hydraulic rod 11, the mounting base 12 and the adjusting connecting rods 13 are moved, thereby adjusting the position of the mounting blocks 9, which means that the distance between the first template 6 and the second template 8 can be adjusted. This allows for flexible changes in the template spacing according to the actual size and construction requirements of the bridge crash barrier, improving the adaptability and versatility of the template construction device, making it suitable for crash barrier construction of different widths.

[0027] like Figure 1 and 2 As shown, the I-beam 2 is connected to the lifting hydraulic rod 10, and the piston rod of the lifting hydraulic rod 10 is connected to the bracket 1. The four vertical rods of the bracket 1 pass through the I-beam 2, and are connected to the mounting seats of the wheels 4, allowing the entire formwork construction device to be moved via the wheels 4. This allows the device to be easily moved to different construction positions on the bridge, improving construction flexibility and efficiency, and reducing the workload and time spent manually handling the formwork. This advantage is particularly pronounced when the bridge is long or the construction positions are dispersed. When the lifting hydraulic rod 10 retracts, it brings the first formwork 6 and the second formwork 8 into contact with the bridge deck, facilitating construction.

[0028] like Figure 1 and 2 As shown, the I-beam 2 is connected to a set of guide cylinders 3, and the four vertical rods of the support 1 are respectively installed in the corresponding guide cylinders 3. When the lifting hydraulic rod 10 drives the support 1 to move up and down, the guide cylinders 3 can guide and limit the vertical rods of the support 1, ensuring that the vertical rods of the support 1 remain vertical and stable during the movement, and preventing the support 1 from tilting or swaying during the movement, thereby improving the stability and reliability of the formwork construction device during the movement.

[0029] The workflow of this embodiment is as follows:

[0030] Based on the width of the crash barrier, adjust the distance between the first template 6 and the second template 8. Place a support plate with wheels on a flat surface, control the extension of the lifting hydraulic rod 10. Since the wheels 4 remain in contact with the ground, they drive the I-beam 2 to move downwards. The I-beam 2 drives the guide rod 5, mounting block 9, first template 6, positioning hole plate 7, and second template 8 to move downwards, so that the first template 6 and the second template 8 respectively contact a support plate. Then, control the extension and retraction of the adjusting hydraulic rod 11. The adjusting hydraulic rod 11 drives the mounting seat 12 to move. The mounting seat 12 drives the adjusting connecting rod 13 to swing. The adjusting connecting rod 13 drives the two mounting blocks 9 to move along the guide rod 5. The two mounting blocks 9 drive the first template 6, positioning hole plate 7, second template 8, and the remaining mounting blocks 9 to move, thus adjusting the distance between the first template 6 and the second template 8.

[0031] During transport, wheels 4 are brought into contact with the ground to facilitate the transfer of the device. Circular holes matching the positioning plate 7 are pre-drilled on the bridge deck. Upon reaching the designated position, a pin is inserted through the positioning hole on the positioning plate 7 and into the circular hole to control the extension of the lifting hydraulic rod 10, causing the first template 6 and the second template 8 to contact the bridge deck. The ends of the first template 6 and the second template 8 are then sealed, and concrete is poured.

[0032] Example 2: This example is a further elaboration based on Example 1, such as... Figure 1 , 2 As shown in Figure 4, a set of guide rods 5 pass through the fixed seat 15 and the movable seat 19 respectively. Each fixed seat 15 is connected to a corresponding guide rod 5, and each fixed seat 15 is rotatably connected to a support rod 16. Each support rod 16 contacts a corresponding second template 8. Each movable seat 19 is rotatably connected to a Y-rod 20, and each Y-rod 20 is rotatably connected to a corresponding support rod 16. The support rods 16 provide auxiliary support for the second template 8, better adapting to the stress changes of the template during construction.

[0033] like Figure 3 and 4 As shown, each of the movable seats 19 is threadedly connected to a bolt 18, and each of the guide rods 5 is provided with a set of positioning holes 14, with the bolt 18 matching the positioning holes 14. Through the cooperation of the bolt 18 and the positioning holes 14, the movable seat 19 can be fixed at a specific position on the guide rod 5, thereby ensuring the stability of the support rod 16.

[0034] After the work is completed, the guide rod 5 and the positioning hole 14 need to be cleaned in time to keep their surfaces clean.

[0035] The workflow of this embodiment is as follows:

[0036] Initially, bolt 18 is tightened into the positioning hole 14 furthest from the second template 8. After adjusting the distance between the first template 6 and the second template 8, bolt 18 is loosened, and the support rod 16 is swung. The support rod 16 drives the Y-rod 20 to swing, and the Y-rod 20 drives the movable seat 19 to move along the guide rod 5. The movable seat 19 drives the bolt 18 to move, so that the support rod 16 contacts the second template 8, and the bolt 18 is tightened into the appropriate positioning hole 14.

[0037] Example 3: This example is a further elaboration based on Example 2, such as... Figure 4 As shown, each of the fixed seats 15 is connected to one end of a spring 17, and each spring 17 is looped around the corresponding guide rod 5. The other end of each spring 17 is connected to the corresponding movable seat 19. The elasticity of the springs 17 ensures that the support rod 16 remains in contact with the second template 8 at all times.

[0038] The workflow of this embodiment is as follows:

[0039] Spring 17 is always in a compressed state. When adjusting the extension and retraction of hydraulic rod 11, support rod 16 and second template 8 always remain in contact. When second template 8 moves, support rod 16 swings under the elastic force of spring 17. Support rod 16 drives Y rod 20 to swing. Y rod 20 and spring 17 drive moving seat 19 to move along guide rod 5. After adjustment, tighten bolt 18 into the appropriate positioning hole 14.

[0040] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
