Description

Technical Field

[0001] The utility model relates to the technical field of earthquake resistance and shock absorption (vibration reduction) of high-rise and super-high-rise structures, and particularly relates to a composite window type damper. Background Art

[0002] At present, in the structural design of high-rise and super-high-rise buildings, the response to earthquakes and wind vibrations is a key consideration. Existing earthquake resistance, isolation and shock absorption technologies have their limitations: traditional earthquake-resistant structures are limited in terms of economy and earthquake resistance, isolation structures are prone to excessive deformation and inelastic residual deformation in strong earthquakes, and ordinary shock absorption systems are affected by the lateral stiffness resistance in high-rise buildings, with limited effects. In addition, the layer-by-layer arrangement method of traditional dampers may interfere with building functions and increase project costs.

[0003] When an earthquake occurs, the building will displace longitudinally and laterally with the seismic wave, resulting in the distortion of the door and window frames, and at the same time, it will also generate strong stress on the glass inside the frame, causing the glass to break and fall, posing a safety hazard. At the same time, a weak layer will be formed, resulting in uneven stress on the overall structure. Summary of the Invention

[0004] In order to solve the problems of the prior art, aiming at the problems of the installation space occupation of the damper and the weak layer of the window, a composite window type damper is provided, which converts the inter-story displacement of the building into the relative displacement of the damper through the deformation of the window frame of the composite window damper to achieve energy dissipation.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. The elements and features described in one embodiment of the present utility model can be combined with those shown in one or more other embodiments. It should be noted that, for the sake of clarity, the representation and description of components and processes unrelated to the present utility model and known to those of ordinary skill in the art are omitted in the description. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0031] The following further describes the present utility model in conjunction with the accompanying drawings: A composite window type damper includes an outer window frame 1, an inner frame 2, a damping material 3, a diaphragm 4 and a cylindrical pin 5. The outer window frame 1 or the inner frame 2 is connected to the diaphragm 4 through the cylindrical pin 5. The damping material 3 is arranged between the outer window frame 1 or the inner frame 2 and the diaphragm 4, and is used to bear the horizontal force and dissipate energy to achieve the vibration damping effect.

[0032] See Figure 1 Among them, the outer window frame 11 is of E type, and the inner frame 2 is of I type.

[0033] Example 1: See Figure 5 The composite window type damper of the present utility model adopts a two-clamping-one form, that is, two layers of outer window frames 1 or inner frames 2 are embedded with one layer of diaphragm 4, and damping materials 3 are attached to both sides of each layer of diaphragm 4. On both sides of each layer of damping material 3 are the outer window frame 1 or the inner frame 2 and the diaphragm 4 respectively. The damping material 3 is selected as a rubber-lead-zinc damping material. It also adopts a three-clamping-two form, that is, three layers of outer window frames 1 or inner frames 2 are embedded with two layers of diaphragms 4, and damping materials 3 are attached to both sides of each layer of diaphragm 4. On both sides of each layer of damping material 3 are the outer window frame 1 or the inner frame 2 and the diaphragm 4 respectively.

[0034] Preferably, the rubber-lead-zinc damping material exhibits significant high damping performance, good durability and stability, customizability, and the characteristics of significantly improving structural safety in the field of building seismic isolation. By adding a polymer damping system to the window structure, this material can make full use of the difference in lateral deformation capacity inside and outside the structure, effectively absorb and disperse seismic energy, thereby reducing the impact of earthquakes on high-rise and super-high-rise buildings, infrastructure, and key facilities with extremely high safety requirements such as hospitals, schools, and data centers. The rubber-lead-zinc damping material plays an important role in improving the seismic performance of buildings and protecting the structure from major damage due to its excellent damping effect and flexibility applicable to various energy dissipation systems.

[0035] The working principle of the composite window type damper is as follows:

[0036] The composite window type damper mainly plays a role in damping vibration. While improving the structural damping performance, it can be used as an ordinary window to provide most of the building's usage functions; the beam-column frame mainly bears the horizontal force, and transfers the horizontal force to the new composite window type damper through a flexible connector or the diaphragm 4 and the remaining internal filling materials; the flexible connector connects the new composite window type damper and is used for the uniform deformation of the new composite window type damper to prevent the displacement of the new composite window type damper caused by the horizontal seismic shear force.

[0037] Compared with traditional building structures, by presetting a new type of composite window damper, the problems of difficult construction and long construction period of ordinary shock-absorbing structures are solved. At the same time, the composite new window damper is easy to replace, making the building shock-absorbing effect more significant. Embodiment

[0038] See Figure 1 and Figure 6 The utility model in Embodiment 2 is basically the same as Embodiment 1 above in terms of structural composition. The difference is that the damping material 3 of the composite window damper of the present utility model is a viscoelastic damping material.

[0039] Preferably, the key properties exhibited by viscoelastic damping materials in the field of building seismic isolation include their excellent elastic recovery ability, high damping performance, outstanding durability and environmental adaptability, as well as wide application possibilities. Such materials can quickly return to their original state after being subjected to external forces (such as earthquake vibrations), effectively dispersing and absorbing vibration energy, thereby reducing the impact on the building structure. Their high damping property enables them to reduce the vibration amplitude of buildings and improve the overall safety and stability of the structure. Due to their good durability and ability to adapt to various environmental conditions, viscoelastic damping materials are suitable for long-term protection of buildings against natural disasters such as earthquakes, especially in high-rise and super-high-rise buildings, key infrastructure, and other buildings with high safety requirements. Through their versatility and customizability, viscoelastic damping materials play an indispensable role in enhancing the seismic performance of buildings. Embodiment

[0040] See Figure 1 and Figure 7 The utility model in Embodiment 3 is basically the same as Embodiment 1 above in terms of structural composition. The difference is that the damping material 3 of the composite window damper of the present utility model is SMA.

[0041] Preferably, the application of shape memory alloy (SMA) materials in the field of building seismic isolation highlights their unique shape memory effect, superelastic properties, high energy absorption capacity, as well as outstanding durability and environmental adaptability. These materials can return to their original shape automatically after experiencing deformation, providing an ability to automatically reset under extreme loading conditions such as earthquakes, thereby significantly improving the recovery ability and seismic performance of building structures. The superelastic characteristics of SMA materials allow them to withstand large strains within a wide temperature range without permanent deformation, which is particularly important for coping with complex dynamic loads. This high durability ensures long-term effectiveness, making them an ideal choice for key facilities with extremely high safety requirements such as high-rise buildings, hospitals, and schools. Through their unique properties, SMA materials provide an efficient shock-absorbing and seismic isolation solution for buildings, which can significantly reduce structural damage and ensure the safety of personnel during natural disasters. Embodiment

[0042] See Figure 1 and Figure 8 The utility model in Embodiment 4 is basically the same as Embodiment 1 in terms of structural composition. The difference is that the damping material 3 of the composite window type damper of the present utility model is a composite damping material.

[0043] Preferably, the application of composite damping materials in the field of building seismic isolation highlights their comprehensive performance of combining the advantages of multiple materials, including high-efficient energy absorption and dissipation capabilities, excellent durability and environmental adaptability, and high customizability for specific requirements. By compounding different types of damping materials (such as elastic materials, viscous materials, and metal damping materials, etc.), these materials not only provide the high damping performance required by the structure under seismic or other dynamic loads, but also maintain good elastic recovery characteristics, ensuring that the building can quickly return to its original state after being shaken. The durability and adaptability of composite damping materials enable them to work effectively for a long time under a wide range of environmental conditions, and are particularly suitable for high-rise and super-high-rise buildings, key infrastructure, etc., where extremely high requirements are placed on structural safety and stability. Through the carefully designed composite structure, these materials play a key role in improving the overall seismic performance of buildings and extending their service life, making them an indispensable part of modern building seismic design. Embodiment

[0044] See Figure 1 and Figure 9 The utility model in Embodiment 5 is basically the same as Embodiment 1 in terms of structural composition. The difference is that the damping material 3 of the composite window type damper of the present utility model is a friction damping material.

[0045] Preferably, friction damping materials demonstrate their excellent energy dissipation capabilities, adjustability, long-term stability, and wide adaptability in the field of building seismic isolation. These materials utilize the relative movement between friction interfaces to dissipate the kinetic energy accumulated by the structure during vibration or earthquake, thereby significantly reducing the response of the building and improving its seismic performance. The design of the friction damping system allows for the adjustment of the magnitude of the damping force to adapt to different structural requirements and earthquake intensities, providing a highly flexible and effective seismic reduction strategy. Its stable performance ensures the long-term ability to withstand natural disasters, and is particularly suitable for high-rise buildings and key infrastructure that require significant seismic reduction effects. The application of friction damping materials not only increases the safety and reliability of building structures, but also becomes an important technical option in seismic design due to its design flexibility and effectiveness. Embodiment

[0046] See Figure 2 and Figures 5 to 10, the utility model in Embodiment 7 is basically the same in structural composition as Embodiment 1 above. The difference is that a metal damper 6 is added at the 100 mm gap reserved between the outer window frame and the inner frame of the novel composite window type damper of the present utility model. Embodiment 2 of the composite window type damper of the present utility model includes an outer window frame 1, an inner frame 2, a damping material 3, a cross partition 4, a cylindrical pin 5 and a metal damper 6. The metal damper 6 is arranged at the 100 mm gap between the outer window frame 1 and the inner frame 2 to further improve the shock absorption effect of the structure. The damping material 3 of the composite window type damper of the present utility model is a friction damping material.

[0047] Preferably, the key contributions of metal dampers in the field of building seismic isolation are reflected in their high energy absorption capacity, stable damping characteristics, good durability and reliability, and adaptability to different working conditions. These devices absorb and dissipate the energy generated by the structure during earthquakes or vibrations through the plastic deformation of metal materials, effectively reducing the response amplitude of buildings. Metal damper designs can meet various building needs, including displacement type metal dampers, metal buckling dampers, etc., providing customized solutions. Their excellent durability means that they can maintain performance for a long time and maintain a stable damping effect even in harsh environments, making them suitable for application in high-rise buildings and key facilities with high safety requirements. The application of metal dampers enhances the resistance of building structures to seismic motion and is an effective shock absorption measure, which helps to protect the structure from earthquake damage.
