[0002] The building structure energy dissipation and vibration reduction technology refers to setting dampers at specific positions of the structure. The dampers consume the energy acting on the structure by converting the structural deformation into their own deformation, thereby improving the safety of the structure. Commonly used dampers can be divided into shear dampers and tension-compression type dampers according to their mechanical properties. Although the existing dampers can reduce the structural response by increasing the damping of the structure to dissipate the structural vibration energy, the layout of the dampers will occupy the space of the building and the structure, affecting the use of building functions or the aesthetics of the building. How to arrange the dampers has become a problem restricting their application. Secondly, there is still a large room for improvement in the energy dissipation rate of the dampers. Designing a new type of efficiency-enhancing damper to solve the damper layout problem has great engineering application requirements. Summary of the Invention

Detailed Description of the Invention

[0031] 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 that are irrelevant to the present utility model and known to those of ordinary skill in the art are omitted. 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.

[0032] The following further describes the present utility model with reference to the drawings: A composite window - type corner - enhancing damper includes an outer window frame 1, a corner - amplifying mechanism 2, an energy - dissipating damping material 3, an inner window frame 4, and a rotating cylindrical pin 5. The outer window frame 1 and the inner window frame 4 are hinged through the rotating cylindrical pin 5, and the corner - amplifying mechanism 2 is hinged to the outer window frame 1 and the inner window frame 4 through the rotating cylindrical pin. The energy - dissipating damping material 3 is filled between the outer window frame 1 and the inner window frame 3 to bear the horizontal force and dissipate energy to achieve a vibration - damping effect.

[0033] Embodiment 1: Refer to Figure 1 and Figure 3 , the composite window - type corner - enhancing damper of the present utility model adopts a form of multi - layer alternating arrangement, that is, an outer frame layer, a damping layer, an inner window frame, and connections are alternately stacked. The corner - amplifying mechanism is embedded between the outer frame and the inner window frame. The two connecting rods of the corner - amplifying mechanism are respectively hinged to the outer window frame 1 and the inner window frame 4, and energy - dissipating damping materials 3 are attached to both sides of the connecting rods. The energy - dissipating damping material 3 is selected as a rubber - lead - zinc energy - dissipating damping material. The composite window damper is connected to the upper and lower beam - column joints or upper and lower beams of the building structure layer through upper and lower connecting members.

[0034] Preferably, the energy - dissipating damping material is selected as a rubber - lead - zinc energy - dissipating damping material. The rubber - lead - zinc energy - dissipating damping material has shown remarkable high - damping performance, excellent durability and stability, and customizability in the field of building shock absorption. This material can effectively utilize the difference in the lateral deformation ability inside and outside the structure, fully 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, etc.). The rubber - lead - zinc energy - dissipating damping material is of great significance in enhancing the seismic performance of buildings and protecting structures from serious damage due to its excellent shock - damping effect and flexibility in applying to various energy - dissipating systems.

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

[0036] The composite window - type corner - enhancing damper mainly functions as a shock absorber. While improving the structural shock - absorption performance, it can be used as an ordinary window, providing most of the building's usage functions. The beam - column frame mainly bears the horizontal force and transfers the horizontal force to the new - type composite window - type damper through a flexible connector or the inner window frame 4 and the rest of the internal filling materials. Under the action of the horizontal force, the outer window frame and the inner window frame rotate relative to each other, and the outer window frame drives the short connecting rod to rotate relatively, generating an angle α. The short connecting rod and the long connecting rod are connected by a sliding bolt, and the sliding bolt can slide in the chute to drive the long connecting rod to generate an angle β. Thus, the corner - amplifying mechanism amplifies the rotation. The energy - dissipating damping materials attached to both sides of the corner - amplifying mechanism undergo shear deformation to dissipate energy, achieving the purpose of amplifying shock absorption.

[0037] Compared with traditional building structures, by presetting the new - type composite window - type corner - enhancing damper, the problems of difficult construction and long construction period of ordinary shock - absorption structures are solved. At the same time, the composite new - type window damper is attached with a corner - amplifying mechanism, which is easy to replace, making the building shock - absorption effect more significant. Embodiment 2

[0038] See Figure 1 、 Figure 2 and Figure 5 In terms of structural composition, the utility model in Embodiment 2 is basically the same as Embodiment 1 above. The difference is that the energy - dissipating damping material 3 of the composite window - type corner - enhancing damper of the present utility model is a visco - elastic energy - dissipating damping material.

[0039] Preferably, visco - elastic energy - dissipating damping materials are increasingly widely used in the field of building seismic isolation. It has excellent elastic recovery ability, high damping performance, excellent durability and environmental adaptability. Such materials can quickly return to their original state after bearing external forces (such as earthquake vibrations), effectively dispersing and absorbing vibration energy, thus greatly reducing the impact on the building structure. The high damping property can effectively reduce the vibration amplitude of the building, improving the overall safety and stability of the structure. Its good durability and self - adaptability enable visco - elastic energy - dissipating damping materials to adapt to different external environments and be used for a long time. Due to these characteristics, visco - elastic materials have played an indispensable role in the field of building shock absorption in recent years, especially in high - rise and super - high - rise buildings, key infrastructure and other buildings with high safety requirements. Embodiment 3

[0040] See Figure 1 、 Figure 2 and Figure 6 In terms of structural composition, the utility model in Embodiment 3 is basically the same as Embodiment 1 above. The difference is that the energy - dissipating damping material 3 of the composite window - type corner - enhancing damper of the present utility model is SMA.

[0041] Preferably, shape memory alloy (SMA) is usually used to manufacture the core components of intelligent seismic isolation devices or shock absorbers. SMA can restore its shape according to preset conditions and has excellent elasticity, durability, and stability. The recoverability of SMA means that it can quickly return to its original shape after being stressed, effectively absorbing and reducing the impact of earthquakes or other vibrations on buildings. The durability and stability of SMA enable it to be used in various environments and ensure its performance for a long time without frequent maintenance. Example 4

[0042] See Figure 1 、 Figure 2 and Figure 7 、The utility model in Example 4 is basically the same as the above-mentioned Example 1 in terms of structural composition. The difference is that the energy-dissipating damping material 3 of the composite window-type corner efficiency-enhancing damper of the present utility model is a composite energy-dissipating damping material.

[0043] Preferably, the composite energy-dissipating damping material is a material that combines multiple different materials or mechanisms, aiming to provide more effective shock absorption and damping effects. These materials are usually composed of a base material (such as metal, polymer, rubber, etc.) and damping fillers (such as particles, fibers, etc.), as well as possible damping mechanisms (such as friction, viscosity, etc.). The composite energy-dissipating damping material can utilize different mechanisms to absorb and disperse seismic or vibration energy, so it can provide better shock absorption effects than single materials. The composite energy-dissipating damping material is flexible in use and can usually be customized according to specific building designs and requirements to meet the shock absorption needs of different building structures. Example 5

[0044] See Figure 1 、 Figure 2 and Figure 8 、The utility model in Example 5 is basically the same as the above-mentioned Example 1 in terms of structural composition. The difference is that the energy-dissipating damping material 3 of the composite window-type corner efficiency-enhancing damper of the present utility model is a friction energy-dissipating damping material.

[0045] The friction energy-dissipating damping material is usually composed of metal plates, polymers, or composite materials. These materials can generate frictional forces during vibration, thereby absorbing and dispersing vibration energy. The friction energy-dissipating damping material can effectively control the vibration of building structures by increasing the damping of the structure, reducing the impact of earthquakes or wind vibrations on buildings. The friction energy-dissipating damping material itself usually does not require regular maintenance and has a long service life, which can reduce the operating cost of buildings. The friction damping system usually has a certain degree of adjustability and can be adjusted according to actual needs to meet the requirements under different vibration conditions. Example 6

[0046] See Figure 1 andFigure 2 and Figure 9 、The utility model in Embodiment 7 is basically the same in structural composition as Embodiment 1 above. The difference is that a metal damper 10 is added at the 100 mm gap reserved between the outer window frame and the inner frame of the novel composite window type corner efficiency - increasing damper of the present utility model. The metal damper 10 is arranged at the 100 mm gap between the outer window frame 1 and the inner frame 2, and is used to further improve the shock - absorption effect of the structure. The energy - dissipating damping material 3 of the composite window type corner efficiency - increasing damper of the present utility model is a friction energy - dissipating 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 requirements, 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 can maintain a stable damping effect even in harsh environments, making them suitable for high - rise buildings and key facilities with high safety requirements. The application of metal dampers enhances the resistance of building structures to seismic ground motion, is an effective shock - absorption measure, and helps to protect the structure from earthquake damage. Embodiment 7

[0048] The utility model in Embodiment 7 is basically the same in structural composition as Embodiment 1 above. The difference is that the corner magnification mechanism of the present utility model is placed at four positions: up, down, left, and right.

[0049] The present utility model is a spatially two - sided symmetric sandwich structure. The outer layer is a C - shaped outer window frame, the middle layer is a rectangular inner window frame. The outer window frame and the inner window frame are provided with a corner magnification mechanism and an energy - dissipating damping material.

The composite window type corner efficiency - increasing damper is connected to the beam - column joints of the building structure through a cable set at the pin shaft, or is connected to the upper and lower beams of the wall or the building structure through the upper and lower beams provided on the inner window frame; The present utility model adds a corner magnification mechanism to the novel window damper, magnifies the inter - story displacement of the building structure under earthquake action through the corner magnification mechanism, enables the composite window type corner efficiency - increasing damper to obtain an ideal energy - dissipating effect under a small corner displacement, can efficiently consume building energy, and is convenient to install.
