Description

Technical Field

[0001] This invention relates to the field of building structure protection technology, specifically to a tie rod device for a double-walled structure template of an ultra-long water tank. Background Technology

[0002] In the structural design of water tanks in large water plants, various water treatment structures often have significant characteristics such as large planar dimensions and extremely long structural lengths. Because these ultra-long water tanks are subject to continuous effects from external factors such as temperature changes and humidity contraction during operation and use, large temperature stresses and contraction stresses are easily generated inside the structure. If not handled properly, this can easily lead to quality problems such as tank wall cracking and leakage.

[0003] To effectively release structural stress caused by temperature and humidity changes and ensure the durability and waterproofing performance of the pool structure, a double-walled separation structure is typically adopted in engineering design. This structurally divides the originally monolithic pool into two independent yet adjacent individual pool units. Stress release is achieved through the deformation space between the two walls, thereby reducing the risk of cracking. Conventional design typically involves a continuous structural gap between the two walls, usually controlled within the range of 5cm to 10cm. However, due to the limited size of this gap, actual on-site construction presents significant challenges in formwork erection, tie rod installation, concrete pouring, and subsequent component processing. Limited operational space and inconvenient work conditions also increase the difficulty of quality control.

[0004] The existing conventional construction methods for double-wall structures in the industry are quite cumbersome and have many unreasonable aspects. The specific construction process is as follows: First, conventional formwork systems are erected on both sides of the double-wall structure. The verticality, flatness, and spacing of the formwork are strictly controlled according to the design requirements to ensure that the formwork support is firm and stable and meets the stress requirements of concrete pouring. Then, a piece of foam board with the same size as the joint width is filled at the expansion joint between the two walls. This serves as a temporary filling and isolation component between the two walls to prevent the concrete on both sides from seeping into and sticking together during the concrete pouring process, thus ensuring the independence of the double-wall structure. After the formwork support is completed, ordinary rigid tie rods are used to penetrate the formwork on both sides to fasten and fix the formwork, ensuring that the formwork will not shift or deform during concrete pouring and guaranteeing the quality of the pool wall formation.

[0005] After the double-wall concrete is poured, reaches the designed demolding strength, and the formwork is removed, the subsequent processing procedures are equally complex and fraught with potential risks. This requires manual removal of the exposed sections of the tie rods on the double-wall surface. After removal, the holes left by the tie rods must be filled in stages with shrinkage-compensating cement mortar. Strict control of the mortar mix ratio and construction process is necessary during the filling process. After filling, specialized curing is required to ensure the filled area is dense and crack-free, preventing future leakage. However, in actual construction, removing the tie rods presents significant difficulties. Because the gap between the double walls is inherently narrow (typically only 5cm~10cm) and deep, the operating space for workers is extremely limited. When using cutting methods to remove the tie rods, the cutting tools cannot penetrate deep into the gap, resulting in extremely low construction efficiency and a high risk of collision and damage to the pool wall concrete, leading to secondary quality issues. Therefore, in actual construction, the tie rods often cannot be completely removed and remain inside the double-wall structure.

[0006] More importantly, this conventional construction method deviates significantly from the original design concept of the double-wall structure. The core purpose of the designers using the double-wall structure was to effectively release the enormous stress generated by the temperature and humidity changes in the ultra-long pool. By dividing the originally monolithic main pool structure into two independent pool units, the gap between the two walls provides space for structural deformation, thereby avoiding stress concentration that could lead to pool wall cracking and leakage, and ensuring the durability and safety of the structure. However, the ordinary tie rods used in conventional construction, after penetrating and fixing both pool walls, even after the exposed sections are removed, the remaining rods inside the double walls still connect the two independent pool units to a certain extent, forming a hidden rigid connection, thus undermining the original design intent of the double-wall structure.

[0007] The existence of this rigid connection prevents the double-wall structure from fully releasing the stress generated by temperature and humidity changes as originally designed. Long-term stress accumulation can lead to micro-cracks in the pool walls, which may gradually widen over time, affecting the pool's waterproof performance and structural safety. At the same time, when subjected to earthquakes, the rigid connection between the double walls by tie rods prevents them from generating effective and reasonable relative deformations as designed, thus failing to utilize the energy dissipation function of the double-wall structure under earthquake loads. This results in a significant discrepancy between the structure's stress distribution and the original design calculation model. Ultimately, the completed pool structure does not fully conform to the original design concept in terms of stress performance and deformation characteristics, making it difficult to meet the structural safety and applicability requirements of the design. Summary of the Invention

[0008] This invention provides a double-walled structural template tensioning device for an ultra-long water tank, which is used to at least solve one of the technical problems existing in the background art.

[0009] This invention is achieved through the following technical solution:

[0010] A tie rod device for a double-walled structure template of an ultra-long water tank includes:

[0011] A first snap-fit ​​assembly is used to snap onto one side of the template;

[0012] The second snap-fit ​​assembly is used to snap onto the other side of the template;

[0013] A connecting component is provided, wherein the first snap-fit ​​component and the second snap-fit ​​component are connected via the connecting component;

[0014] The connecting components are arranged in a first state, a second state, and a third state in sequence according to the relative distance between the first snap-fit ​​component and the second snap-fit ​​component.

[0015] When the connecting components are in the first state, the first snap-fit ​​component and the second snap-fit ​​component can slide freely relative to each other;

[0016] When the connecting components are in the second state, the first and second snap-fit ​​components move away from each other against the damping effect of the connecting components;

[0017] When the connecting components are in the third state, the first and second snap-fit ​​components can slide freely relative to each other.

[0018] In some alternative embodiments, the connection component includes:

[0019] A first connector is connected to the first snap-fit ​​assembly;

[0020] The second connector is connected to the second snap-fit ​​assembly;

[0021] A third connector is provided, through which the first and second connectors are connected. The third connector releases the connection between the first and second connectors in response to the magnitude of the tension in the first and second connectors.

[0022] In some alternative embodiments, the third connecting component is configured as a ring with a fracture guide port.

[0023] In some alternative embodiments, the third connecting component is configured as a chain link, wherein the break guide is configured as a notch.

[0024] In some optional embodiments, the first buckle assembly includes:

[0025] The first rod has one end connected to the connecting assembly and the other end penetrating the template.

[0026] The first fastener is connected to the other end of the first rod and abuts against the template.

[0027] In some alternative embodiments, a first water-stop wing ring is also connected to the first rod.

[0028] In some optional embodiments, the second snap-fit ​​assembly includes:

[0029] The second rod has one end connected to the connecting assembly and the other end penetrating the template;

[0030] The second fastener is connected to the other end of the second rod and abuts against the template.

[0031] In some alternative embodiments, a second water-stop wing ring is also connected to the second rod.

[0032] In some alternative embodiments, both the first and second snap-fit ​​components are provided with protrusions.

[0033] In some alternative embodiments, the protrusion is configured as a threaded protrusion.

[0034] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0035] This invention employs a gradient mechanical response design where the connecting components sequentially present a first state, a second state, and a third state as the relative distance between the first and second snap-fit ​​components increases. This allows the template tensioning device to automatically adapt to different constraint modes under different service conditions of the double-wall structure: In the first state during normal use, the two pool walls are allowed to slide freely, releasing temperature and shrinkage stresses caused by temperature and humidity changes, preventing cracking and leakage. When encountering moderate loads such as design earthquakes, the second state introduces controllable damping force, which not only dissipates seismic energy and buffers dynamic response but also suppresses excessive deformation of the pool walls to protect auxiliary facilities such as expansion joints and waterstops, giving the traditional double-wall structure an active energy dissipation and vibration reduction function. Under rare extreme loads, the third state allows the two... The side walls regain complete freedom, preventing brittle fracture or overall collapse due to rigid constraints through their own safety failure, thus achieving major earthquake protection. The three states are continuously triggered and automatically switched by relative displacement, requiring no manual intervention or additional monitoring, forming a full life-cycle adaptive defense system of normal freedom, energy dissipation during moderate earthquakes, and separation during major earthquakes. At the same time, the device also serves as a formwork tie-fixing component during concrete pouring, and is permanently embedded in the gap between the two walls after forming without the need for removal. This avoids problems in traditional construction such as difficult bolt removal, wall damage from cutting, and poor hole sealing quality caused by narrow gaps. While improving construction efficiency and safety, it also ensures the reliability of the pool wall's waterproofing. This solution achieves a systematic and synergistic improvement in structural stress performance, seismic safety, and construction convenience through state change design.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0046] Example 1

[0047] Please refer to them together. Figures 1-6 This invention provides a double-walled template tensioning device for an ultra-long water tank, which includes a first snap-fit ​​assembly 1, a second snap-fit ​​assembly 2, and a connecting assembly 3.

[0048] The first snap-fit ​​component 1 is used to snap onto one side of the template, and the second snap-fit ​​component 2 is used to snap onto the other side of the template. The first snap-fit ​​component 1 and the second snap-fit ​​component 2 are connected by a connecting component 3. The connecting component 3 sequentially changes from a first state to a second state and then to a third state depending on the relative distance between the first snap-fit ​​component 1 and the second snap-fit ​​component 2. When the connecting component 3 is in the first state, the first snap-fit ​​component 1 and the second snap-fit ​​component 2 can slide freely relative to each other. When the connecting component 3 is in the second state, the first snap-fit ​​component 1 and the second snap-fit ​​component 2 move away from each other against the damping effect of the connecting component 3. When the connecting component 3 is in the third state, the first snap-fit ​​component 1 and the second snap-fit ​​component 2 can slide freely relative to each other.

[0049] In this embodiment, the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 are respectively used to snap onto the templates on both sides of the double-wall structure to be poured, serving to fix the templates and control the template spacing. The connecting assembly 3 serves as the component connecting the two. Damping refers to the resistance experienced by the system during movement, which in this solution is specifically manifested as the resistance generated by the connecting assembly 3 on the relative movement of the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2. Traditional tie rods provide a rigid connection throughout the entire service life. In contrast, the connecting component 3 in this design exhibits different mechanical states depending on the relative distance between the two side panels: When the double-wall structure is in normal use and the relative displacement of the two side panels is small (corresponding to the first state), connecting component 3 allows free sliding without any constraint, ensuring the double-wall structure can freely release stress caused by temperature and humidity changes; when the double-wall structure encounters extreme loads such as earthquakes and the relative displacement of the two side panels increases to a certain extent (corresponding to the second state), connecting component 3 begins to generate damping, resisting further separation and absorbing earthquake energy and impact loads; when the relative displacement continues to increase beyond the bearing capacity of connecting component 3 (corresponding to the third state), connecting component 3 disengages, and the two side panels return to a free state, preventing structural damage due to forced constraint. Through these three stages of mechanical response, this design ensures stress release under normal use conditions and provides necessary energy dissipation and safety protection mechanisms under extreme conditions such as earthquakes, overcoming the technical defects of traditional tie rods that always provide a rigid connection and undermine the original design intent of the double-wall structure.

[0050] Example 2

[0051] like Figure 2 As shown, based on Embodiment 1, the connecting component 3 includes a first connector 31, a second connector 32, and a third connector 33. The first connector 31 is connected to the first snap-fit ​​component 1, and the second connector 32 is connected to the second snap-fit ​​component 2. The first connector 31 and the second connector 32 are connected through the third connector 33. The third connector 33 releases the connection between the first connector 31 and the second connector 32 in response to the magnitude of the tension of the first connector 31 and the second connector 32. Since the tensioning device does not need to be removed after molding, in actual implementation, the first connector 31 and the second connector 32 can be fixedly connected to the first snap-fit ​​component 1 and the second snap-fit ​​component 2 by welding, respectively.

[0052] In this embodiment, the first connector 31 is fixedly connected to the first snap-fit ​​assembly 1, and the second connector 32 is fixedly connected to the second snap-fit ​​assembly 2. The two are detachably connected by the third connector 33. The connection between the first connector 31 and the second connector 32 is released in response to the magnitude of the tensile force. When the relative distance between the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 increases to a certain extent, the tensile force between the first connector 31 and the second connector 32 increases accordingly. When this tensile force exceeds the limit that the third connector 33 can withstand, the third connector 33 breaks or detaches, thereby releasing the connection between the first connector 31 and the second connector 32. Through this structural design, the three-stage mechanical response of the connecting component 3 is achieved: in the normal use stage (first state), the first connecting member 31 and the second connecting member 32 are connected by the third connecting member 33 but relative sliding is allowed without generating substantial constraints; in the medium displacement stage (second state), as the tensile force increases, the third connecting member 33 generates a damping effect to resist the separation of the two; in the large displacement stage (third state), the third connecting member 33 breaks and releases after exceeding the bearing limit, and the first snap-fit ​​component 1 and the second snap-fit ​​component 2 are completely separated and restored to a free state.

[0053] Preferably, such as Figure 3 As shown, the third connector 33 is configured as an annular member, and the annular member has a fracture guide port 331.

[0054] In this embodiment, the annular component can be a circular ring, an elliptical ring, or other closed ring structure, which surrounds the connection between the first connector 31 and the second connector 32, serving to tighten and connect them. The fracture guide opening 331 is a pre-designated weak area on the annular component, typically in the form of a notch, a notch, a thinned section, or a stress concentration groove. When the tensile force between the first connector 31 and the second connector 32 increases, the annular component as a whole bears tensile stress. Due to the smallest cross-sectional area or stress concentration effect at the fracture guide opening 331, this area becomes the area of ​​maximum stress on the annular component. When the tensile force reaches a preset threshold, fracture occurs first at the fracture guide opening 331, leading to the failure of the entire annular component, and the connection between the first connector 31 and the second connector 32 is released. By setting the fracture guide opening 331, the fracture load of the third connector 33 can be controlled, allowing it to fracture accurately under a predetermined tensile force value, thereby achieving the switching between the second and third states. Furthermore, the fracture guide opening 331 makes the fracture location of the annular component predictable and controllable, avoiding uncontrollable failure modes caused by the annular component breaking at unexpected locations, thus improving the overall reliability and safety of the device. In this embodiment, the annular component can be made of a metal material (such as low-carbon steel, stainless steel, etc.), and its fracture load can be designed by adjusting the cross-sectional dimensions of the annular component, the material strength, and the depth and shape of the fracture guide opening 331. In other embodiments, the annular component can also be made of polymer materials or composite materials.

[0055] Furthermore, the third connector 33 is configured as a chain link, wherein the break guide 331 is configured as a notch.

[0056] In this embodiment, the chain link is a ring-shaped component in the chain structure used to connect adjacent chain links, and it has a certain load-bearing capacity and deformation capacity. By configuring the third connector 33 as a chain link, the expected mechanical response can be achieved by utilizing the chain link's good tensile strength and well-defined fracture characteristics. Chain links are typically made of metal materials through bending or casting; their ring structure can effectively transmit tensile force while allowing relative rotation and slippage under certain conditions. The fracture guide 331 is specifically configured as a notch, i.e., an opening or groove made on the ring body of the chain link. The shape of the notch can be V-shaped, U-shaped, semi-circular, or rectangular, etc., and its depth and width determine the effective load-bearing cross-sectional area at that location. When the chain link is subjected to tensile force, stress concentration occurs at the notch, becoming the weakest point of the entire link. By designing the geometric parameters of the notch, it can be ensured that the chain link accurately breaks at the notch under a preset tensile force value, thus releasing the connection. The chain link structure has advantages such as simple structure, low manufacturing cost, and good fracture controllability, making it particularly suitable for single-use construction scenarios. In other embodiments, the chain links may also be standard or custom parts of different specifications and materials to meet the needs of double-walled structures of different sizes and different load conditions.

[0057] Preferably, the first connector 31 and the second connector 32 can be readily available chain links, and multiple first connectors 31 and multiple second connectors 32 respectively form a chain structure. In particular, the first connector 31 connected to the first buckle assembly 1 is semi-ring shaped, and the end faces of the semi-ring are welded to the first buckle assembly 1. Correspondingly, the second connector 32 connected to the second buckle assembly 2 is also semi-ring shaped, and its end faces are welded to the second buckle assembly 2.

[0058] Example 3

[0059] like Figure 4 As shown, based on any of the above embodiments, the first snap-fit ​​assembly 1 includes a first rod 11 and a first fastener 12. One end of the first rod 11 is connected to the connecting assembly 3, and the other end of the first rod 11 passes through the template; the first fastener 12 is connected to the other end of the first rod 11 and abuts against the template.

[0060] In this embodiment, the first rod 11 is an intermediate force-transmitting component connecting the connecting assembly 3 and the template. One end of the rod is fixedly connected to the first connecting member 31 of the connecting assembly 3, and the other end extends through a pre-set mounting hole on the template to the outside of the template. The first fastening member 12 is installed on the end of the first rod 11 that extends out of the template, and achieves the fastening and fixing of the template by abutting against the outer surface of the template. The first fastening member 12 can be in the form of a nut, washer, clamp, or special fastener. When it is necessary to fix the template, the first fastening member 12 is tightened or pressed to make the first fastening member 12 tightly abut against the outer surface of the template, and together with the second clamping assembly 2, clamps and fixes the templates on both sides. This allows the first clamping assembly 1 to not only firmly fix the template, but also to transmit the force of the template to the connecting assembly 3 through the first rod 11, realizing a complete force transmission path between the template, the clamping assembly, and the connecting assembly 3. During the concrete pouring process, the first clamping assembly 1 can effectively resist the lateral pressure of the concrete, prevent the template from shifting or deforming, and ensure the forming accuracy of the pool wall.

[0061] Preferably, a first water-stop wing ring 13 is also connected to the first rod 11.

[0062] In this embodiment, the first water-stop wing ring 13 is an annular water-stopping component disposed on the first rod 11. It is typically made of a metal plate, formed into a ring shape, and welded or fitted onto the outer periphery of the first rod 11. The function of the first water-stop wing ring 13 is to form multiple water-stopping barriers around the first rod 11 after concrete pouring, preventing water leakage along the interface between the first rod 11 and the concrete. Specifically, after the concrete is poured and hardened, a portion of the first rod 11 is embedded inside the pool wall concrete. Since the first rod 11 and the concrete are two different materials, the interface between them easily becomes a channel for water penetration. The placement of the first water-stop wing ring 13 increases the path length and resistance of water penetration along the surface of the rod, thereby effectively improving the waterproof performance of the pool wall. The first water-stop wing ring 13 is typically disposed in the middle region of the first rod 11 in the thickness direction of the pool wall to ensure that it is completely encased in concrete. In other embodiments, the first water-stop wing ring 13 can also adopt other water-stopping structural forms, such as water-stop grooves, water-stop flanges, or water-stop sleeves. The first water-stop wing ring 13 enables the device to meet the template tie function while also taking into account the waterproof requirements of the pool structure, thus avoiding the risk of leakage caused by the tie rod penetrating the wall.

[0063] Example 4

[0064] like Figure 5 As shown, based on any of the above embodiments, the second snap-fit ​​assembly 2 includes a second rod 21 and a second fastener 22. One end of the second rod 21 is connected to the connecting assembly 3, and the other end of the second rod 21 passes through the template; the second fastener 22 is connected to the other end of the second rod 21 and abuts against the template.

[0065] In this embodiment, the structure and function of the second rod 21 and the second fastener 22 correspond to those of the first rod 11 and the first fastener 12, respectively. One end of the second rod 21 is fixedly connected to the second connector 32 of the connecting assembly 3, and the other end extends out of the template through the mounting hole on the other side of the template. The second fastener 22 is installed on the end of the second rod 21 that extends out of the template, and fastens and fixes the template on the other side by abutting against the outer surface of the template. The first fastening assembly 1 and the second fastening assembly 2 are located on the two sides of the pool wall of the double-wall structure, and the two are connected to each other in the gap between the double walls through the connecting assembly 3. During construction, the first rod 11 is first passed through the mounting hole of one side of the template and the first fastener 12 is installed. Then, the second rod 21 is passed through the mounting hole of the other side of the template and the second fastener 22 is installed. By adjusting the tightness of the fasteners on both sides, the templates on both sides can be fixed in the designed position. This symmetrical structural design makes the force on the template tensioning device more balanced and the fixing effect of the templates on both sides more reliable. The first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 can adopt the same structural form and specifications to simplify manufacturing and construction operations; or they can adopt different structural forms according to actual needs to adapt to different stress conditions or different construction requirements of the two side formworks.

[0066] Preferably, a second water-stop wing ring 23 is also connected to the second rod 21.

[0067] In this embodiment, the structure and function of the second water-stop wing ring 23 are the same as those of the first water-stop wing ring 13. The second water-stop wing ring 23 is set on the second rod 21, located in the part of the second rod 21 embedded in the concrete of the pool wall, and is used to prevent water leakage along the interface between the second rod 21 and the concrete. The first water-stop wing ring 13 and the second water-stop wing ring 23 correspond to the two side pool walls of the double-wall structure, and each plays a water-stopping role independently. By setting water-stop wing rings on the first rod 11 and the second rod 21 respectively, the entire template tie device has a reliable waterproof structure at every point of penetration through the two side pool walls, ensuring the overall waterproof performance of the double-wall pool structure. The first water-stop wing ring 13 and the second water-stop wing ring 23 can use the same material, size and installation method to simplify the manufacturing process; or different water-stop wing ring specifications can be used according to the different thicknesses or different waterproof level requirements of the two side pool walls.

[0068] Example 5

[0069] Based on any of the above embodiments, both the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 are provided with protrusions.

[0070] In this embodiment, the protrusions are raised structures provided on the surfaces of the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2. Their function is to enhance the friction between the snap-fit ​​assembly and the template or to provide additional positioning functionality. During the template tensioning process, the snap-fit ​​assembly needs to transmit the fastening force by abutting against the template. If the contact surface between the snap-fit ​​assembly and the template is too smooth, the snap-fit ​​assembly may slip relative to the template under the vibration or lateral pressure generated by concrete pouring, leading to inaccurate template positioning. The protrusions increase the contact pressure and friction coefficient between the snap-fit ​​assembly and the template, effectively preventing the snap-fit ​​assembly from slipping and ensuring the positional stability of the template throughout the concrete pouring process. In addition, the protrusions can also serve a positioning function, achieving rapid and accurate alignment between the snap-fit ​​assembly and the template by cooperating with pre-set grooves or holes on the template, thus improving construction efficiency. In this embodiment, the protrusions can be distributed in different forms such as dots, strips, rings, or grids. In other embodiments, the protrusions can also take other forms, such as knurling, indentation, or embedded friction pads. Additionally, the protrusions on the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 can also interact with the concrete, thereby limiting the position of the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 through the concrete, ensuring the positional accuracy of the first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2.

[0071] Preferably, the protrusion is configured as a threaded protrusion.

[0072] In this embodiment, the protrusion is specifically in the form of a threaded protrusion. A threaded protrusion, or the tooth profile of a thread, is a helical protrusion structure machined onto the surface of the clamping assembly. By configuring the protrusion as a threaded protrusion, at least a portion of the surface of the clamping assembly in contact with the template also has a threaded structure. The threaded protrusion provides excellent frictional resistance; the pointed tip of the thread profile forms multiple points of contact with the template surface, generating significant frictional resistance under the tightening force, effectively preventing slippage of the clamping assembly. Furthermore, the threaded protrusion makes the clamping assembly adjustable; by rotating the clamping assembly, the tightening force can be finely adjusted using the helix angle of the thread, making the template fixation more precise and reliable. In this embodiment, the thread on the clamping assembly can be a fine thread or a coarse thread, selected according to the required adjustment precision and tightening force. The threaded protrusion design allows the clamping assembly to have both anti-slip and adjustment functions, further improving the ease of use and construction accuracy of the device.
