Description

Technical Field

[0001] This application relates to the field of auxiliary tools for building construction, and in particular to a positioning device for embedded parts of a temporary tensioning platform for segmental beams. Background Technology

[0002] In the field of bridge construction, segmental beam construction has always been a key focus and a challenging aspect. With the continuous growth in transportation demand and the constant advancement of bridge construction technology, the application of segmental beams is becoming increasingly widespread. The quality of segmental beam construction not only affects the load-bearing capacity and stability of the bridge but also plays a decisive role in its long-term performance and safety. Good segmental beam construction can significantly shorten the construction period, reduce costs, and promote the development of bridge construction to a higher level. Moreover, high-quality segmental beam construction is also of great significance for optimizing bridge structures and enhancing the overall aesthetics of bridges, occupying an indispensable position in modern bridge construction.

[0003] In the construction of segmental beams, various methods have traditionally been used to position the embedded parts on the temporary tensioning platform. A common method is using a grid of reinforcing bars, where bars are welded together in a grid shape to form a relatively fixed frame, within which the embedded parts are placed for positioning. Another method uses positioning steel plates, connecting them to the embedded parts and utilizing the plate's planar properties for initial positioning. Additionally, some construction teams use simple support structures, fixing the embedded parts to the supports with bolts or other connectors for positioning. Furthermore, temporary wooden formwork frames are sometimes used to assist in positioning the embedded parts during construction.

[0004] However, existing positioning methods have significant drawbacks. For example, when using a grid-shaped steel reinforcement for positioning, welding operations can easily burn the embedded parts, affecting their quality and performance. Using positioning steel plates is susceptible to the effects of concrete pouring and vibration, causing the embedded parts to shift and making it difficult to guarantee positioning accuracy. Other simple support structures or wooden formwork frames also fail to meet the requirements for high-precision positioning due to their poor structural stability. Utility Model Content

[0005] In order to significantly improve the positioning accuracy of the embedded parts of the temporary tensioning platform for segmental beams, accelerate the installation process, and ensure construction quality, this utility model provides a positioning device for the embedded parts of the temporary tensioning platform for segmental beams.

[0006] The present invention provides a positioning device for embedded parts of a temporary tensioning platform for segmental beams, which adopts the following technical solution:

[0007] A positioning device for embedded parts on a temporary tensioning platform for segmental beams includes a positioning steel plate, a positioning frame, and a connecting structure for connection with a template. The positioning steel plate is disposed within the positioning frame, and the inner peripheral wall of the positioning frame matches the outer peripheral wall of the positioning steel plate to achieve positioning of the positioning steel plate. The embedded part is connected to the positioning steel plate and fixed by a nut. The connecting structure includes a first steel pipe, a second steel pipe, a third steel pipe, a fourth steel pipe, and a fifth steel pipe. The length directions of the first steel pipe, the second steel pipe, the third steel pipe, the fourth steel pipe, and the fifth steel pipe are all parallel. The positioning frame is aligned with the side wall of the first steel pipe. The second and third steel pipes are respectively located on both sides of the positioning frame and are connected to the positioning frame. The second and third steel pipes have the same length. The fourth and fifth steel pipes correspond one-to-one with the two ends of the first steel pipe. The first end of the first steel pipe and the second steel pipe are both connected to one end of the fourth steel pipe. The second end of the fourth steel pipe is connected to the first end of the template. The second end of the first steel pipe and the third steel pipe are both connected to the first end of the fifth steel pipe. The second end of the fifth steel pipe is connected to the second end of the template. The fourth and fifth steel pipes have the same length.

[0008] By adopting the above technical solution, the positioning steel plate can be accurately positioned by matching the inner peripheral wall of the positioning frame with the outer peripheral wall of the positioning steel plate, thereby enabling the embedded parts to be accurately connected and fixed to the positioning steel plate. Simultaneously, the connecting structure consists of a first steel pipe, a second steel pipe, a third steel pipe, a fourth steel pipe, and a fifth steel pipe. The second and third steel pipes are of the same length and are located on opposite sides of the positioning frame, while the fourth and fifth steel pipes are of the same length and correspond to the two ends of the first steel pipe. This symmetrical structural design not only enhances the stability of the entire device but also makes the stress distribution more uniform, which is beneficial for improving the positioning accuracy and reliability of the embedded parts, ensuring the stability of the connection between the device and the template, and facilitating the accurate positioning of the embedded parts on the temporary tensioning platform of the segmental beam.

[0009] Preferably, the inner wall of the positioning frame is connected to a placement plate, the placement plate is located at the bottom of the positioning frame, and the positioning steel plate abuts against the top of the placement plate.

[0010] By adopting the above technical solution, the positioning frame, together with the positioning steel plate, realizes the positioning of the embedded parts. The placement plate provides support for the positioning steel plate, ensuring the stable installation of the positioning steel plate, thereby making the embedded parts more stable and the positioning more accurate.

[0011] Preferably, the connection structure further includes positioning components, with positioning components connected to both ends of the connection structure. The positioning components are used to connect with the template. Each positioning component includes a base block, a first positioning element, and a second positioning element. The first positioning element and the second positioning element are respectively located on both sides of the base block and are connected to the base block. The base block, the first positioning element, and the second positioning element form a positioning space with a top opening. The connection structure is engaged in the positioning space to achieve positioning of the connection structure.

[0012] By adopting the above technical solution, the positioning space formed by the bottom block of the positioning component, the first positioning element, and the second positioning element can be used to hold the connecting structure, thereby improving the stability of the connection between the connecting structure and the template and ensuring the accuracy of the installation position of the entire positioning device on the template.

[0013] Preferably, the first steel pipe, the second steel pipe, the third steel pipe, the fourth steel pipe and the fifth steel pipe are all made of galvanized square tubing.

[0014] By adopting the above technical solutions, the corrosion resistance of the connection structure can be improved, the service life of the device can be extended, and the long-term stable use of the positioning device can be guaranteed.

[0015] Preferably, the first steel pipe, the second steel pipe, the fourth steel pipe, and the positioning frame enclose a first space, and the first steel pipe, the third steel pipe, the fifth steel pipe, and the positioning frame enclose a second space. Both the first space and the second space are provided with positioning columns for reserving hoisting holes. Both the first space and the second space are provided with limiting structures, which are connected to the first steel pipe and used to limit the positioning columns.

[0016] By adopting the above technical solution, positioning columns are set in the first space and the second space to reserve hoisting holes, which facilitates the subsequent hoisting work of segment beams; at the same time, a limiting structure is set to limit the positioning columns, which can ensure the accurate position of the positioning columns and guarantee the accuracy of the hoisting hole reservation.

[0017] Preferably, the limiting structure is a limiting sleeve, which is connected to the first steel pipe, and the positioning post is inserted into the limiting sleeve.

[0018] By adopting the above technical solution, the positioning sleeve is connected to the first steel pipe and the positioning column is inserted, which can achieve accurate and stable positioning of the positioning column and ensure the precise position of the reserved hoisting hole.

[0019] Preferably, a plurality of limiting sleeves are provided and spaced apart along the length of the first steel pipe to accommodate segmental beams of different specifications.

[0020] By adopting the above technical solution, multiple limiting sleeves can be set to flexibly adapt to segmental beams of different sizes and parameter requirements, ensuring the stable installation and accurate positioning of the positioning columns during the construction of segmental beams of different specifications.

[0021] Preferably, the limiting structure adopts a sliding groove and a slot. The sliding groove is formed on the first steel pipe, and a plurality of slots are provided and spaced apart along the length direction of the sliding groove. The top of the slot is connected to the sliding groove. The positioning post is connected to a slider that matches the sliding groove. The slider is disposed in the sliding groove and is slidably connected to the first steel pipe, and the slot matches the slider.

[0022] By adopting the above technical solution, the slider connected to the positioning column can slide in the groove of the first steel pipe, allowing the positioning column to move flexibly. Several slots spaced apart along the length of the groove match the slider, which can fix the positioning column in different positions, improving the adaptability of the device to beams of different specifications.

[0023] In summary, this utility model has the following beneficial effects:

[0024] By matching the inner peripheral wall of the positioning frame with the outer peripheral wall of the positioning steel plate, the positioning steel plate can be precisely positioned, allowing the embedded parts to be accurately connected and fixed to the positioning steel plate. Simultaneously, the connecting structure consists of a first steel pipe, a second steel pipe, a third steel pipe, a fourth steel pipe, and a fifth steel pipe. The second and third steel pipes are of the same length and are located on opposite sides of the positioning frame, while the fourth and fifth steel pipes are of the same length and correspond to the two ends of the first steel pipe. This symmetrical structural design not only enhances the stability of the entire device but also makes the stress distribution more even, which is beneficial for improving the positioning accuracy and reliability of the embedded parts, ensuring the stability of the connection between the device and the formwork, and facilitating the accurate positioning of the embedded parts on the temporary tensioning platform of the segmental beam.

[0033] A positioning device for embedded parts of a temporary tensioning platform for segmental beams, referring to Figure 1 It includes a positioning steel plate 1, a positioning frame 2, and a connecting structure 3 for connecting with the template 8. The positioning steel plate 1 is located inside the positioning frame 2, and the inner peripheral wall of the positioning frame matches the outer peripheral wall of the positioning steel plate 1, which can effectively position the positioning steel plate 1. The embedded part is connected to the positioning steel plate 1 and fixed with nuts, so that the embedded part is stable on the positioning steel plate 1.

[0034] Reference Figure 1The connecting structure 3 includes a first steel pipe 31, a second steel pipe 32, a third steel pipe 33, a fourth steel pipe 34, and a fifth steel pipe 35, all of which are parallel in length.

The second steel pipe 32 and the third steel pipe 33 are respectively located on both sides of the positioning frame 2 and are fixedly connected to it, with the second steel pipe 32 and the third steel pipe 33 having the same length. The fourth steel pipe 34 and the fifth steel pipe 35 correspond one-to-one with the two ends of the first steel pipe 31. The first end of the first steel pipe 31 and the second steel pipe 32 are both fixedly connected to one end of the fourth steel pipe 34, and the second end of the fourth steel pipe 34 is connected to the first end of the template 8. The second end of the first steel pipe 31 and the third steel pipe 33 are both fixedly connected to the first end of the fifth steel pipe 35, and the second end of the fifth steel pipe 35 is connected to the second end of the template 8. The fourth steel pipe 34 and the fifth steel pipe 35 have the same length. This connection method ensures a stable connection between the entire device and the template 8, thereby guaranteeing the accuracy of the embedded part positioning.

[0035] The entire device can be stably connected to the formwork 8, preventing the embedded parts from shifting during concrete pouring and vibration. Furthermore, compared to the previous grid-shaped rebar positioning method, it avoids burning the embedded parts, thus improving their quality and performance.

[0036] Reference Figure 2 The positioning steel plate 1 is typically a flat, square metal plate with a thickness of 5mm. The close fit between the positioning steel plate 1 and the positioning frame 2 ensures the precise positioning of the positioning steel plate 1, thereby guaranteeing the accurate positioning of the embedded parts connected to the positioning steel plate 1.

[0037] Reference Figure 2 The bottom of the positioning frame 2 is fixedly connected to the placement plate 21, which is a square frame, and the positioning steel plate 1 abuts against the top of the placement plate 21.

[0038] The placement plate 21 provides support for the positioning steel plate 1, ensuring the stable installation of the positioning steel plate 1, thereby making the installation of the embedded parts more stable and the positioning more accurate.

[0039] Reference Figure 1 The first steel pipe 31, the second steel pipe 32, the third steel pipe 33, the fourth steel pipe 34, and the fifth steel pipe 35 can all be made of galvanized square tubing. This material has good rust resistance, and its wall thickness should be selected according to the actual load-bearing requirements. The first steel pipe 31, the second steel pipe 32, the third steel pipe 33, the fourth steel pipe 34, and the fifth steel pipe 35 are mainly connected by welding. The weld points must be ground to ensure the reliability of the connection.

[0040] Reference Figure 1 The device also includes a positioning component 4. Both ends of the connecting structure 3 are connected to the positioning component 4, which is used to connect with the template 8.

[0041] Reference Figure 1 The positioning component 4 includes a base block 41, a first positioning element 42, and a second positioning element 43. The base block 41 is fixedly connected to the mold. The first positioning element 42 and the second positioning element 43 are respectively located on both sides of the base block 41 and are fixedly connected to the base block 41. The base block 41, the first positioning element 42, and the second positioning element 43 form a positioning space with a top opening. The connecting structure 3 is engaged in the positioning space to achieve the positioning of the connecting structure 3.

[0042] The first positioning element 42 and the second positioning element 43 are made of galvanized square tubing and are connected to both sides of the base block 41 by welding or bolting. The size of the positioning space is determined according to the dimensions of the connecting structure 3 to ensure that the connecting structure 3 can be tightly engaged.

[0043] Reference Figure 1 The first steel pipe 31, the second steel pipe 32, the fourth steel pipe 34, and the positioning frame 2 enclose a first space. The first steel pipe 31, the third steel pipe 33, the fifth steel pipe 35, and the positioning frame 2 enclose a second space. Both the first and second spaces are equipped with positioning posts 5 for pre-drilling hoisting holes. The positioning posts 5 are cylindrical metal rods with handles attached to their tops for easy handling.

[0044] Reference Figure 1 Both the first space and the second space are equipped with limiting structures 6, which are connected to the first steel pipe 31 and are used to limit the positioning column 5.

[0045] The function of the limiting structure 6 is to ensure that the position of the positioning post 5 is fixed in space and will not shake or shift.

[0046] Reference Figure 1 When the limiting structure 6 uses a limiting sleeve 61, the limiting sleeve 61 is fixedly connected to both the first steel pipe 31 and the second steel pipe 32, and the positioning post 5 is inserted into the limiting sleeve 61. The limiting sleeve 61 is a square cylindrical structure, and the inner wall length of the limiting sleeve 61 matches the outer diameter of the positioning post 5.

[0047] Reference Figure 1 Several limiting sleeves 61 are provided and spaced apart along the length of the first steel pipe 31, which can accommodate segmental beams of different specifications.

[0048] Reference Figure 3When the limiting structure 6 adopts a sliding groove 62 and a locking groove 63, the sliding groove 62 is simultaneously formed on the first steel pipe 31, the second steel pipe 32, and the third steel pipe 33. Two sliding grooves 62 are symmetrically formed on the first steel pipe 31. The sliding groove 62 on the second steel pipe 32 corresponds to one sliding groove 62 on the first steel pipe 31, and the sliding groove 62 on the third steel pipe 33 corresponds symmetrically to the other sliding groove 62 on the first steel pipe 31. Each sliding groove 62 corresponds to several locking grooves 63, the top of which communicates with the sliding groove 62. The several locking grooves 63 are spaced apart along the length of the sliding groove 62.

[0049] Reference Figure 3 Both sides of the positioning post 5 are fixedly connected to sliders 7, which can be square or round block structures. Slider 7 matches the slide groove 62, is located within the slide groove 62, and is slidably connected to the first steel pipe 31. The slot 63 matches the slider 7 and is used to hold the slider 7 in place.

[0050] By sliding the slider 7 within the groove 62 and then locking it into different slots 63, the position of the positioning column 5 can be adjusted to accommodate segmental beams of different specifications.

[0051] The operating principle of this application is as follows: Through a reasonable structural design, the positioning device for the embedded parts of the temporary tensioning platform for segmental beams ensures that the positioning steel plate 1 is precisely positioned within the positioning frame 2, and the connecting structure 3 is securely connected to the template 8. This avoids the problems of the embedded parts shifting or being burned due to concrete pouring and vibration, thus guaranteeing the positioning accuracy and quality of the embedded parts. Simultaneously, the placement of the positioning components 4, positioning columns 5, and various types of limiting structures 6 improves the versatility and flexibility of the device, enabling it to adapt to segmental beams of different specifications, representing a significant improvement and enhancement compared to existing technologies.
