Description

Technical Field

[0001] This application relates to the field of building construction technology, and more specifically, to a pier formwork tie system. Background Technology

[0002] With the acceleration of urbanization, various roads and facilities are increasing. In urban transportation construction projects, it is often necessary to build overpasses, viaducts or other bridges, which are supported by piers.

[0003] The related technology utilizes vase-shaped piers to support the bridge. Specifically, a vase-shaped pier is formed by two piers positioned opposite each other, creating a vase-like structure. This design better distributes the load, enhances structural stability, and in some cases, reduces material usage and lowers costs. The vase-shaped pier shape also makes the space beneath the bridge more open, improving the overall transparency of the bridge and minimizing its impact on the landscape. Furthermore, the design of the vase-shaped piers can be customized to meet different cultural and environmental needs, making them more regionally distinctive and culturally significant.

[0004] Generally, the pier formwork is erected first, and then the pier body is formed by pouring concrete onto the formwork. Therefore, the shape of the pier formwork corresponds to the vase-shaped pier body. However, because the top of the vase-shaped pier body is more outward-wider than the bottom, and the top of the pier formwork for making the vase-shaped pier body is also more outward-wider than the bottom, the center of gravity of the pier formwork will deviate from the vertical direction where the bottom of the pier body is located, thus leading to a higher risk of the pier formwork overturning. Utility Model Content

[0005] This application addresses the shortcomings of existing methods by proposing a tie-down system for pier formwork, which solves the technical problem of high risk of pier formwork overturning in related technologies.

[0006] In the first aspect, embodiments of this application provide a pier formwork tie system, comprising: pier formwork and at least one tie rod.

[0007] The pier formwork is set up in pairs facing each other. The pier formwork includes a vertical part set on the ground and an expansion part located above the vertical part. The expansion part gradually expands outward from the bottom to the top. In the horizontal direction, the center of gravity of the vertical part of the two pier formworks is located between the center of gravity of the expansion part of the two pier formworks.

[0008] The two ends of the tie rod are used to connect with the expansion sections of the two oppositely arranged pier body templates.

[0009] In some possible embodiments, in two pier body templates arranged opposite each other, the opposite sides of the pier body templates include a first side plate portion.

[0010] The first side plate of the expansion section is equipped with a connecting structure.

[0011] The tie rod and the connecting structure are detachably connected.

[0012] In some possible embodiments, the end of the pull rod is fixedly connected to at least two coaxially arranged nuts through the connecting structure.

[0013] In some possible embodiments, the number of pull rods is at least two.

[0014] Multiple tie rods are arranged in parallel.

[0015] In some possible embodiments, at least two tie rods have a first design height.

[0016] At least two tie rods have a second design height.

[0017] The first design height is different from the second design height.

[0018] In some possible embodiments, two tie rods of the same height are arranged side by side and are respectively connected to the area near the edge of the first side plate of the expansion.

[0019] In some possible embodiments, the longitudinal dimensions of the pier formwork are consistent, and the orthographic projections of the tie rods with different heights on the ground at least partially overlap.

[0020] The longitudinal direction is perpendicular to the height of the pier formwork and parallel to the first side plate of the pier formwork.

[0021] In some possible embodiments, the first design height is the same as the height of the center position of the expansion.

[0022] In some possible embodiments, the second design height is greater than the first design height but less than the height of the top of the expansion portion.

[0023] In some possible embodiments, the two pier formworks arranged opposite each other are mirror symmetrical.

[0024] The beneficial technical effects of the technical solutions provided in this application include:

[0025] The pier formwork is arranged in pairs facing each other, used to cast and form the piers that support the bridge. In these pairs of facing pier formwork, the vertical sections are vertically aligned, while the expanding sections extend outwards in opposite directions, causing the overall center of gravity of the pier formwork to point outwards. The tie rods are rod-shaped, possessing a certain rigidity, facilitating installation between the facing pier formwork sections and improving the installation efficiency of the pier formwork tie system. Furthermore, the tie rods enable the spaced-apart pier formwork sections to form a unified whole, with the formwork sections mutually restraining each other, thus improving the structural stability of the pier formwork tie system and reducing the risk of pier formwork overturning.

[0043] The research and development ideas of this application include: In related technologies, guy ropes are used to connect two pier formworks that are set up opposite each other. However, guy ropes are easily affected by the external environment, and the installation process is complicated and time-consuming.

[0044] Moreover, when the pier construction site is located above the road, the installation of guy ropes is more difficult in order not to affect road traffic.

[0045] The pier formwork tie system provided in this application is intended to solve the above-mentioned technical problems in related technologies.

[0046] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0047] This application embodiment provides a pier formwork tie system 100, the main view structural schematic diagram of the pier formwork tie system 100 is shown below. Figure 1 As shown, the side view structural diagram of the pier body formwork tie system 100 is as follows: Figure 3 As shown, the top view of the tie-up system 100 for the pier body formwork is as follows: Figure 4 As shown, it includes: pier body formwork 10 and at least one tie rod 20.

[0048] The pier body templates 10 are arranged in pairs facing each other. Each pier body template 10 includes a column 11 set on the ground and an expansion portion 12 located on the column 11. The expansion portion 12 gradually expands outward from the bottom to the top. In the horizontal direction, the center of gravity of the column 11 of the two pier body templates 10 is located between the center of gravity of the expansion portion 12 of the two pier body templates 10.

[0049] The two ends of the tie rod 20 are respectively used to connect with the expansion parts 12 of the two oppositely arranged pier body templates 10.

[0050] In this embodiment, the pier formwork 10 is arranged in pairs facing each other, used to cast and form the piers supporting the bridge. In the pairs of facing pier formwork 10, the column portion 11 is vertically arranged, and the expansion portion 12 expands outward in a direction away from each other, so that the center of gravity of the pier formwork 10 is outward. The tie rod 20 is a rod-shaped object with a certain rigidity, facilitating installation by construction personnel between the facing pier formwork 10, and improving the installation efficiency of the pier formwork tie system 100. Moreover, the tie rod 20 enables the two spaced-apart pier formwork 10s to form a whole, with the pier formwork 10s mutually restraining each other, which can improve the structural stability of the pier formwork tie system 100, thereby reducing the risk of overturning of the pier formwork 10.

[0051] Optionally, the column portion 11 is used to form the column portion 11 of the pier body during the first pouring, and the expansion portion 12 is used to form the expansion portion 12 of the pier body during the second pouring.

[0052] It is understandable that the piers are used to support the bridge. Two piers set opposite each other form a group of piers. Multiple groups of piers need to be set along the extension direction of the bridge. Correspondingly, multiple pier templates 10 form piers. Two pier templates 10 set opposite each other form a group of pier templates 10. Multiple groups of pier templates 10 are set along the extension direction of the bridge, which can also be called longitudinal Y. The width direction of the bridge is called transverse X, and the extension direction of the pier is called vertical Z.

[0053] In some possible embodiments, such as Figure 1-2 and Figure 4 As shown, among the two pier body templates 10 arranged opposite each other, the opposite sides of the pier body template 10 include the first side plate portion 14.

[0054] The first side plate portion 14 of the expansion portion 12 is provided with a connecting structure 121.

[0055] The tie rod 20 is detachably connected to the connecting structure 121.

[0056] In this embodiment, among the two pier body templates 10 arranged opposite each other, the side of the expansion portion 12 of one pier body template 10 facing the expansion portion 12 of the other pier body template 10 is a first side plate portion 14. The first side plate portion 14 of the expansion portion 12 is provided with a connecting structure 121, which can be detachably connected to the end of the tie rod 20. This allows the pier body template 10 and the tie rod 20 to be transported and installed separately. Compared with the overall structure formed by the pier body template 10 and the tie rod 20, the pier body template tie system 100 provided in this embodiment can reduce transportation costs, enhance structural flexibility, and facilitate inspection or replacement.

[0057] In some possible embodiments, such as Figure 2 As shown, the end of the tie rod 20 passes through the connecting structure 121 and is fixedly connected to at least two coaxially arranged nuts 13.

[0058] In this embodiment, the connecting structure 121 has a hole-like structure, such as a connecting hole. The end of the tie rod 20 can pass through the hole-like structure of the connecting structure 121 and then be fastened by at least two coaxially arranged nuts 13 to ensure a stable connection between the tie rod 20 and the expansion portion 12.

[0059] For example, two nuts 13 are coaxially arranged to form a double nut, which makes the connection with the tie rod 20 more secure.

[0060] Optionally, the tie rod 20 includes a body and an end. The diameter of the end of the tie rod 20 is slightly smaller than that of the body. When the end of the tie rod 20 passes through the connecting structure 121, the connecting structure 121 is confined between the body of the tie rod 20 and the double nuts 13, making the connection between the tie rod 20 and the connecting structure 121 more stable and eliminating the need for additional fasteners, thereby reducing structural complexity and cost.

[0061] In some possible embodiments, the number of levers 20 is at least two.

[0062] Multiple tie rods 20 are arranged in parallel.

[0063] In this embodiment, multiple tie rods 20 are arranged in parallel and are all parallel to the ground, which further enhances the stability between the two oppositely arranged pier formwork 10 and reduces the possibility of the pier formwork 10 overturning.

[0064] In some possible embodiments, such as Figure 1 As shown, at least two tie rods 20 have a first design height H1.

[0065] At least two tie rods 20 have a second design height H2.

[0066] The first design height H1 is different from the second design height H2.

[0067] In this embodiment, multiple tie rods 20 can be staggered in the vertical direction Z to connect multiple points between the expansion portions 12 of the two oppositely arranged pier body templates 10, which can disperse the tension of the tie rods 20 and increase the load-bearing capacity of the tie rods 20.

[0068] In some possible embodiments, two tie rods 20 of the same height are arranged side by side and are respectively connected to the area near the edge of the first side plate portion 14 of the expansion portion 12.

[0069] In this embodiment, the longitudinal direction Y of the first side plate portion 14 of the expansion portion 12 has a certain width, and two tie rods 20 are arranged side by side in the longitudinal direction Y, respectively connected to the area near the edge of the first side plate portion 14 of the expansion portion 12, so that the two tie rods 20 can be evenly stressed, reducing single-point load and improving the balance of the pier body formwork tie system 100.

[0070] In some possible embodiments, the longitudinal dimensions of the pier formwork 10 are consistent, and the orthographic projections of the tie rods 20 with different heights on the ground at least partially overlap.

[0071] The longitudinal direction is perpendicular to the height of the pier body formwork 10 and parallel to the first side plate portion 14 of the pier body formwork 10.

[0072] In this embodiment, the longitudinal dimension of the pier template 10 can also be referred to as the width of the longitudinal Y of the pier template 10. The longitudinal Y can be understood as the extension direction of the bridge supported by the pier. Tie rods 20 of different heights are arranged sequentially in the vertical Z direction, which can save longitudinal Y space.

[0073] In some possible embodiments, such as Figure 1 As shown, the first design height H1 is the same as the height of the center position of the expansion part 12.

[0074] In this embodiment, the tie rod 20 with the first design height H1 is set at the midpoint of the expansion part 12 in the vertical direction Z, which can improve the stability and balance of the pier body template tie system 100.

[0075] In some possible embodiments, such as Figure 1 As shown, the second design height H2 is greater than the first design height H1, but less than the height of the top of the expansion section 12.

[0076] In this embodiment, the expansion angle of the expansion section 12 is larger as it gets closer to the top. The tie rod 20 with the second design height H2 is set at a position slightly above the expansion section 12, which can distribute the force load on the tie rod 20 and further ensure the stability and balance of the pier body formwork tie system 100.

[0077] In some possible embodiments, such as Figure 1 and Figure 4As shown, the two pier body templates 10 set opposite to each other are mirror symmetrical.

[0078] In this embodiment, the two pier body templates 10 arranged opposite each other are mirror symmetrical, and the tie rods 20 can ensure that the forces at both ends are even as much as possible, thereby ensuring the overall stability and balance of the pier body template tie system 100.

[0079] By applying the embodiments of this application, at least the following beneficial effects can be achieved:

[0080] 1. The tie rod 20 can be moved as a whole via the casters 30. It can be pre-installed in other locations and then moved under the construction equipment, with minimal impact from traffic on the road 200, making it relatively easy to implement. The canopy 10 of the tie rod 20 isolates the construction equipment from the road 200 below it, providing protection for vehicles passing through the road 200. There is no need to temporarily erect the tie rod 20 on the road 200; it can be directly moved away via the casters 30 after use, reducing the amount of work involved in setting up and dismantling the tie rod 20. 2. The space between adjacent support components 22 forms a passage 21 on the road 200, allowing vehicles to pass through. The canopy 10 provides protection for vehicles. Furthermore, the casters 30 are located at the bottom of the support components 22, allowing the tie rod 20 to be moved simply by pushing the support components 22.

[0081] 2. In the two pier body templates 10 arranged opposite to each other, the side of the expansion portion 12 of one pier body template 10 facing the expansion portion 12 of the other pier body template 10 is a first side plate portion 14. The first side plate portion 14 of the expansion portion 12 is provided with a connecting structure 121, which can be detachably connected to the end of the tie rod 20. This allows the pier body template 10 and the tie rod 20 to be transported and installed separately. Compared with the integral structure formed by the pier body template 10 and the tie rod 20, the pier body template tie system 100 provided in this application embodiment can reduce transportation costs, enhance structural flexibility, and facilitate inspection or replacement.

[0082] 3. Multiple tie rods 20 can be staggered in the vertical direction Z to connect multiple points between the expansion parts 12 of the two oppositely arranged pier body templates 10, which can disperse the tension of the tie rods 20 and increase the load-bearing capacity of the tie rods 20.

[0083] 4. The longitudinal Y of the first side plate 14 of the expansion section 12 has a certain width. Two tie rods 20 are arranged in parallel along the longitudinal Y and are respectively connected to the area near the edge of the first side plate 14 of the expansion section 12, so that the two tie rods 20 can be evenly stressed, reducing single-point load and improving the balance of the pier formwork tie system 100.

[0084] 5. The longitudinal dimension of the pier formwork 10 can also be called the width of the longitudinal Y of the pier formwork 10. The longitudinal Y can be understood as the extension direction of the bridge supported by the pier. Tie rods 20 of different heights are set in sequence in the vertical Z direction, which can save longitudinal Y space.

[0085] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0086] The above description is only a partial implementation of this application. It should be noted that for those skilled in the art, other similar implementation methods based on the technical concept of this application, without departing from the technical concept of this application, also fall within the protection scope of the embodiments of this application.
