Description

Technical Field

[0001] This application relates to the technical field of building structural engineering, and in particular to horizontal force transmission devices. Background Technology

[0002] In the field of building structural engineering, especially in cases involving adjacent large main buildings, how to safely and effectively transfer horizontal loads (such as earth pressure, seismic or wind loads) between them has always been a key issue.

[0003] While traditional rigid connection methods can effectively transmit force, they completely constrain the vertical relative deformation between structures, which not only generates significant secondary stress on the main structure but also affects the vertical vibration reduction and isolation effect of components such as vibration isolation supports.

[0004] Therefore, it is urgent to design a horizontal force transmission device structure to achieve reliable transmission of horizontal forces between adjacent building structures while allowing a suitable amount of vertical relative displacement. Utility Model Content

[0005] In order to achieve reliable transmission of horizontal forces between adjacent building structures while allowing appropriate vertical relative displacement, thereby improving the safety and adaptability of the connection between adjacent building structures, this application provides a horizontal force transmission device.

[0006] The horizontal force transmission device provided in this application adopts the following technical solution: A horizontal force transmission device, installed between a first main building and a second main building, is characterized by comprising pre-tensioning end plates and a connecting mechanism. The pre-tensioning end plates are arranged in two sets symmetrically, and the two sets of pre-tensioning end plates are respectively mounted on the first and second main buildings via a first fixing component and a second fixing component. The connecting mechanism is disposed between the two sets of pre-tensioning end plates and is used to connect the two sets of pre-tensioning end plates. The connecting mechanism includes: A vertical deformation assembly is disposed between two sets of pre-tightened end plates. The vertical deformation assembly is used to transmit the horizontal force between the two sets of pre-tightened end plates and allow the two sets of pre-tightened end plates to move vertically relative to each other. A limiting member is disposed on the pre-tightening end plate, and the limiting member is used to limit the relative displacement between the vertical deformation component and the pre-tightening end plate; Preload bolts, multiple sets of the preload bolts are used to connect two sets of preload end plates and apply preload force to the vertical deformation assembly. The preload end plates are provided with elongated holes for the preload bolts to pass through, and the elongated holes allow the preload bolts to slide vertically on the preload end plates.

[0007] By adopting the above technical solution, the force between the first main building and the second main building is transmitted to two sets of pre-tightened end plates, and then the horizontal force is transmitted between the two pre-tightened end plates through the vertical deformation component. When the building undergoes vertical relative displacement, the pre-tightening bolts can slide in the elongated hole, and at the same time, the vertical deformation component itself deforms or slides to adapt to the displacement. When the displacement exceeds the limit, the limiting component contacts the vertical deformation component to form a rigid stop, ensuring reliable force flow transmission between the main structures, while avoiding additional internal forces caused by constrained vertical deformation, and ensuring safety in extreme cases through the limiting mechanism. This achieves reliable transmission of horizontal force between adjacent building structures while allowing a suitable amount of vertical relative displacement.

[0008] Furthermore, the vertical deformation component is a roller assembly, which includes multiple rollers with horizontally arranged axes and stacked vertically. The roller assembly is housed between two pre-tightening end plates and simultaneously rolls against the two sets of pre-tightening end plates.

[0009] By adopting the above technical solution, the horizontal force is transmitted through the contact between the roller and the end plate by utilizing the low friction characteristics of rolling; the vertical displacement is adapted by the rotation of the roller and the sliding of the pre-tightening bolt in the elongated hole. It has high force transmission efficiency, low friction loss, and smooth vertical movement, and is suitable for situations that are sensitive to friction or require frequent micro-movements.

[0010] Furthermore, the vertical deformation component is an elastic body, which is housed between the two pre-tightening end plates and simultaneously abuts against the two sets of pre-tightening end plates. The elastic body can undergo axial compression deformation to transmit horizontal loads, and the elastic body can undergo shear deformation to adapt to vertical relative displacement.

[0011] By adopting the above technical solution, the deformation capacity of elastic materials is utilized, and horizontal force is transmitted through the axial compression deformation of the elastic body, while vertical displacement is adapted through the shear deformation of the elastic body. It has a certain damping and vibration isolation effect, can absorb some energy, buffer impact loads, and at the same time, the deformation of the elastic body can adapt to a certain degree of deflection and installation error.

[0012] Furthermore, the vertical deformation component is a low-friction sliding assembly, which includes a polytetrafluoroethylene (PTFE) plate and a first steel plate. The PTFE plate is disposed on a set of pre-tightening end plates, and the first steel plate is disposed on another set of pre-tightening end plates. A coating for reducing the coefficient of friction is disposed near the PTFE plate. The coatings of the PTFE plate and the first steel plate form a low-friction sliding pair.

[0013] By adopting the above technical solution, the horizontal force is transmitted through the static friction between the PTFE plate and the coated steel plate interface, and the vertical displacement is achieved through the relative sliding between the two interfaces. Its structure is relatively simple and compact, has good durability, and can provide stable sliding friction performance, making it suitable for situations with large forces.

[0014] Furthermore, the limiting member is a stop block provided on the pre-tightening end plate. When the stop block abuts against the vertical deformation component, it prevents the vertical deformation component from continuing to slide relative to the pre-tightening end plate. Two sets of stop blocks are provided and are used to limit the displacement of the vertical deformation component in two relative directions.

[0015] By adopting the above technical solution, the stop block acts as a physical limiting mechanism. When the vertical deformation component comes into contact with the stop block due to excessive displacement, the movement is stopped, thus providing the final safety guarantee and preventing the device from failing or damaging the main structure due to excessive displacement, and controlling the displacement within the safe range allowed by the design.

[0016] Furthermore, one of the pre-tightening end plates is equipped with a force sensor, which is located between the pre-tightening end plate and the vertical deformation component and is used to monitor the pressure value between the pre-tightening end plate and the vertical deformation component in real time.

[0017] By adopting the above technical solution, the force sensor is integrated into the force transmission path, converting the sensed mechanical pressure into an electrical signal output, realizing real-time monitoring and digitization of the transmitted force, which facilitates the assessment of structural safety status and early warning.

[0018] Furthermore, the first fixing component includes: An embedded end plate is pre-embedded in the first main building structure by multiple sets of anchor bars. A connecting end plate is abutted against a pre-embedded end plate and locked in place by fixing bolts; The connector is used to fix the connecting end plate and the pre-tightening end plate together. The structure of the second fixing component is the same as that of the first fixing component and they are arranged symmetrically.

[0019] By adopting the above technical solution, the pre-embedded end plate ensures a firm anchorage with the main structure; the connecting end plate serves as a conversion component; and the connector is used to connect and adjust the final position, thereby providing a standardized and reliable connection method with the main structure.

[0020] Furthermore, the connectors are available in various lengths. By selecting connectors of different lengths, the overall length of the horizontal force transmission device can be fine-tuned to accommodate changes in the distance between the first and second main buildings. By adopting the above technical solution and changing the lever arm length between the fixing component and the pre-tightening end plate by replacing the connectors of different lengths, the construction error is compensated, the on-site adaptability and installation fault tolerance of the device are improved, and the construction progress and quality are guaranteed.

[0021] Furthermore, the pre-tightening end plate and the connecting mechanism are prefabricated components and can be pre-stressed in the factory.

[0022] By adopting the above technical solutions, the assembled device is tested under pre-pressure in a factory-controlled environment to ensure that the product's performance meets design requirements, thereby improving engineering quality and safety; reducing on-site commissioning workload and shortening the construction period.

[0023] Furthermore, when the stop block comes into contact with the adjacent pre-tightening end plate, it prevents further compression of the elastomer.

[0024] By adopting the above technical solution, when the elastomer is compressed to the allowable horizontal deformation of the main building structure, the stop block contacts the adjacent pre-tightened end plate to prevent the elastomer from being compressed further, thereby limiting the relative deformation of the main building structure.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Horizontal forces are transmitted to the pre-tightening end plate via a fixed assembly. The pre-tightening end plate applies horizontal pressure to the roller assembly, which in turn transmits the force to the opposite pre-tightening end plate, and then to the adjacent structure, achieving effective transmission of horizontal forces. When vertical relative displacement occurs between the two buildings, the pre-tightening bolts can slide vertically within the elongated holes of the pre-tightening end plate. Simultaneously, the rollers adjust to this displacement through rotation, ensuring that the device does not generate constraint bending moments. If the displacement is too large, the roller assembly moves as a whole until it contacts the stop block. The stop block, through rigid blocking, restricts further rolling, thereby limiting the inter-story displacement of the main structure and providing protection. The entire device achieves reliable transmission of horizontal forces between adjacent building structures while allowing for a suitable amount of vertical relative displacement, improving the safety and adaptability of the connection between adjacent building structures.

[0026] 2. The horizontal load is transferred to the elastic body through the pre-tightened end plate. The elastic body undergoes axial compression deformation, thereby effectively transferring the horizontal force to the adjacent structure. When the two building structures experience vertical relative displacement, the elastic body mainly undergoes shear deformation to adapt to this displacement, ensuring vertical freedom and avoiding constraints on the main structure. If the vertical displacement is too large, causing the shear deformation of the elastic body to approach its limit, the auxiliary block and the stop block work together to limit the further deformation of the elastic body and prevent it from shearing failure. Under extreme overload conditions, the contact interface between the elastic body and the second steel plate can undergo relative slippage, which serves as an overload protection mechanism to further release stress and protect the elastic body itself and the main structure. While effectively transmitting force, this device absorbs some energy through the deformation of the elastic body, thus possessing a certain degree of vibration reduction and isolation effect.

[0027] 3. By using a friction pair formed by the pre-tightening end plate pressing the polytetrafluoroethylene (PTFE) plate and the coated first steel plate, the static friction between the materials is used to achieve effective horizontal force transmission. When the two building structures undergo vertical relative displacement, the low-friction coating interface between the PTFE plate and the first steel plate slides, thereby adapting to the vertical displacement and avoiding the generation of constraint bending moment. This low-friction sliding pair ensures smooth and stable vertical sliding. This scheme reliably achieves the core functions of horizontal force transmission and vertical deformation adaptation through a simple planar sliding friction pair, and has a compact structure and good durability.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0031] This application discloses a horizontal force transmission device.

[0032] Example 1 Reference Figure 1 and Figure 2 A horizontal force transmission device is installed between the first main building 1 and the second main building 2. The horizontal force transmission device includes a pre-tightening end plate 3 and a connecting mechanism 4. There are two sets of pre-tightening end plates 3, which are symmetrically arranged. The two sets of pre-tightening end plates 3 are respectively installed on the first main building 1 and the second main building 2 through the first fixing component 11 and the second fixing component 21. The connecting mechanism 4 is installed between the two sets of pre-tightening end plates 3 and is used to connect the two sets of pre-tightening end plates 3.

[0033] Reference Figure 2 The connecting mechanism 4 is disposed between two sets of pre-tightened end plates 3. The connecting mechanism 4 includes a vertical deformation component 5, a limiting member 41, and pre-tightening bolts 42. The vertical deformation component 5 can effectively transmit horizontal forces in two directions, while allowing a certain degree of vertical relative displacement between the two sets of pre-tightened end plates 3. The limiting member 41 is installed on the pre-tightened end plate 3, and its function is to work in conjunction with the vertical deformation component 5 to prevent further movement when the relative slippage exceeds the design allowable range, thereby protecting the main structure. Multiple sets of pre-tightening bolts 42 are provided, which pass through the two sets of pre-tightened end plates 3 and apply pre-tightening force by tightening to press the internal vertical deformation component 5. In particular, an elongated hole is machined on the pre-tightened end plate 3, and the pre-tightening bolt 42 can slide vertically within the elongated hole, thereby accommodating the relative vertical displacement of the building structure.

[0034] Reference Figure 2The vertical deformation component 5 is in the form of a roller group 51, which is composed of multiple horizontally arranged rollers 51 stacked vertically and housed between two pre-tightened end plates 3. The rollers 51 have rolling contact with the end plates, which ensures effective transmission of horizontal force and greatly reduces friction during vertical movement. When the first main building 1 and the second main building 2 undergo vertical relative displacement, the rollers 51 can rotate to adjust, and the entire device can still maintain stable mechanical properties.

[0035] Reference Figure 2 The limiting component 41 is a stop block 411 set on the pre-tightening end plate 3. The position of the stop block 411 is precisely designed. When the displacement of the outermost roller 51 relative to the pre-tightening end plate 3 reaches a predetermined limit value, the stop block 411 will contact it and prevent it from continuing to roll, thereby preventing excessive deformation of the structure and protecting the safety of the main building. A set of stop blocks 411 is set in each of the two directions of the roller 51's rolling to achieve bidirectional limiting. In this embodiment, both stop blocks 411 are set on the same pre-tightening end plate 3, and the distance between the two sets of stop blocks is greater than the sum of the diameters of multiple sets of rollers 51.

[0036] Reference Figure 2 In order to monitor the force transmission status in real time, a force sensor 6 is fixedly installed between one of the pre-tightening end plates 3 and the roller 51. This sensor can monitor and output the pressure value between the two, providing important data support for structural health monitoring.

[0037] Reference Figure 1 Two sets of pre-tightened end plates 3 are respectively set on the first main building 1 and the second main building 2 by the first fixing component 11 and the second fixing component 21. The first fixing component 11 and the second fixing component 21 have the same structure and are arranged symmetrically. The first fixing component 11 fixes one set of pre-tightened end plates 3 on the first main building 1, and the second fixing component 21 fixes the other set of pre-tightened end plates 3 on the second main building 2.

[0038] Reference Figure 1 and Figure 2 The first fixing component 11 includes a pre-embedded end plate 111, a connecting end plate 112, and a connector 113. The pre-embedded end plate 111 is pre-embedded in the concrete structure of the first main building 1 by multiple anchor bars 114. The connecting end plate 112 is tightly connected to the pre-embedded end plate 111 by high-strength fixing bolts. The connector 113 is used to connect the connecting end plate 112 and the pre-tightening end plate 3.

[0039] Reference Figure 2 The connector 113 has various length specifications. By selecting standard connectors 113 of different lengths, the total length of the horizontal force transmission device can be finely adjusted to adapt to the unavoidable building spacing deviations during on-site construction, thereby improving construction efficiency and accuracy.

[0040] Reference Figure 2 The pre-tightening end plate 3 and the connecting mechanism 4 of the device can be prefabricated components. They can be prefabricated and pre-pressurized in the factory to ensure that their mechanical properties meet the design requirements before being transported to the site for installation with the connecting parts 113. This greatly ensures the quality of the project and shortens the construction period.

[0041] Reference Figure 2 This horizontal force transmission device successfully achieves efficient and reliable transmission of horizontal loads between the first main building 1 and the second main building 2 through the rolling and sliding of multiple sets of rollers 51 on the pre-tightening end face. At the same time, it allows vertical relative displacement of the two sets of pre-tightening end plates 3 and provides rigid protection through the limiting member 41 under extreme working conditions such as earthquakes. Its modular, adjustable and monitorable features make it widely applicable, have excellent mechanical properties and high engineering practical value.

[0042] The working principle of Embodiment 1 of this application is as follows: When horizontal forces such as earthquakes or wind loads act on the first main building 1 or the second main building 2, the horizontal force is transmitted to the pre-tightening end plate 3 through the fixing components. The pre-tightening end plate 3 applies horizontal pressure to the roller 51 group, which in turn transmits the force to the opposite pre-tightening end plate 3 through its contact, and then to the adjacent structure, thus achieving effective transmission of horizontal force. When vertical relative displacement occurs between the two buildings, the pre-tightening bolt 42 can slide vertically within the elongated hole of the pre-tightening end plate 3. At the same time, the roller 51 adjusts to this displacement by rotating, ensuring that the device does not generate a constraint bending moment. If the displacement is too large, the roller 51 group moves as a whole until it contacts the stop block 411. The stop block 411 restricts further rolling by rigidly blocking it, thereby limiting the inter-story displacement of the main structure and playing a protective role. The entire device achieves reliable transmission of horizontal force between adjacent building structures while allowing a suitable amount of vertical relative displacement, improving the safety and adaptability of the connection between adjacent building structures.

[0043] Example 2 Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the vertical deformation component 5 is an elastic body 52, which is clamped between two pre-tightened end plates 3. When subjected to a horizontal load, the elastic body 52 mainly undergoes axial compression deformation to transmit the horizontal force; when a vertical relative displacement occurs, the elastic body 52 undergoes shear deformation to adapt. This design provides a certain degree of shock absorption and vibration isolation while transmitting force.

[0044] Reference Figure 4Another set of pre-tightening end plates 3 is also provided with auxiliary blocks 412. The auxiliary blocks 412 and the stop blocks 411 are symmetrically arranged. The auxiliary blocks 412 and the stop blocks 411 cooperate with each other to prevent the elastic block from deforming too much and limit the maximum deformation of the elastic body 52. ​​In this embodiment, when the elastic body 52 is compressed to the allowable horizontal deformation of the main building structure, the two opposing stop blocks 411 and auxiliary blocks 412 abut against each other to prevent the elastic body 52 from being compressed further, thereby limiting the relative deformation of the main building structure.

[0045] Reference Figure 4 A second steel plate 521 is provided on the side of the elastic body 52 away from the force sensor 6. The elastic body 52 and the second steel plate 521 can slide relative to each other, so that when the two sets of pre-tightening end plates 3 move vertically relative to each other, the elastic body 52 will first adapt by shearing deformation. As its shearing force continues to increase, the elastic body 52 can slide on the second steel plate 521, thereby reducing the probability of shearing damage to the elastic body 52.

[0046] The working principle of Embodiment 2 of this application is as follows: Horizontal loads are transmitted to the elastic body 52 through the pre-tightened end plate 3. The elastic body 52 undergoes axial compression deformation, thereby effectively transmitting the horizontal force to the adjacent structure. When the two building structures undergo vertical relative displacement, the elastic body 52 mainly undergoes shear deformation to adapt to this displacement, ensuring vertical freedom and avoiding constraints on the main structure. If the vertical displacement is too large, causing the shear deformation of the elastic body 52 to approach its limit, the auxiliary block 412 and the stop block 411 work together to limit the further deformation of the elastic body 52 and prevent it from shearing failure. Under extreme overload conditions, the contact interface between the elastic body 52 and the second steel plate 521 can undergo relative slippage, which serves as an overload protection mechanism to further release stress and protect the elastic body 52 itself and the main structure. While effectively transmitting force, this device absorbs some energy through the deformation of the elastic body 52, thus possessing a certain degree of vibration reduction and isolation effect.

[0047] Example 3 Reference Figure 5 and Figure 6The difference between this embodiment and Embodiment 1 is that the vertical deformation component 5 is a low-friction sliding assembly 53. The low-friction sliding assembly 53 includes a polytetrafluoroethylene (PTFE) plate 531 and a first steel plate 532 with a special low-friction coating. The PTFE plate 531 is fixed to the pre-tightening end plate 3 at one end, and the coated steel plate is fixed to the pre-tightening end plate 3 at the other end. Its coating surface is located on the side of the first steel plate 532 near the PTFE plate 531. The PTFE plate 531 and the coating surface contact to form a pair of low-friction sliding pairs. Its horizontal force is transmitted by squeezing the PTFE plate 531 and the first steel plate 532, and at the same time by the PTFE plate 531 sliding on the coating surface, thereby allowing the two sets of pre-tightening end plates 3 to slide easily vertically relative to each other.

[0048] Reference Figure 6 A force sensor 6 is provided on the side of the polytetrafluoroethylene plate 531 away from the first steel plate 532. The force sensor 6 is used to transmit the horizontal force between the pre-tightening end plate 3 and the polytetrafluoroethylene plate 531, and at the same time monitor the magnitude of the force.

[0049] The working principle of Embodiment 3 of this application is as follows: The horizontal force is effectively transmitted horizontally by pressing the friction pair formed by the polytetrafluoroethylene plate 531 and the coated first steel plate 532 through the pre-tightening end plate 3, utilizing the static friction between the materials. When the two building structures undergo vertical relative displacement, the low-friction coating interface between the polytetrafluoroethylene plate 531 and the first steel plate 532 slides, thereby adapting to the vertical displacement and avoiding the generation of constraint bending moment. This low-friction sliding pair ensures the smoothness and stability of vertical sliding. This scheme reliably achieves the core functions of horizontal force transmission and vertical deformation adaptation through a simple planar sliding friction pair, and has a compact structure and good durability.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
