Description

[Technical Field]

[0001] The present invention relates to a vibration control structure for wall-plate frames, and more specifically to a vibration control structure that generates a frictional force in-plane due to seismic energy, generates a reverse inertial force out-of-plane, and generates a restoring force out-of-plane due to wind vibrations that causes gravity to properly restore the frame, thereby reducing the amplitude of vibrations caused by earthquakes or wind using these three forces. [Background technology]

[0002] In earthquake-prone areas and maritime nations surrounded by the sea, damage from earthquakes and various levels of wind damage is unavoidable. In order to reduce damage from earthquakes and wind damage, it has been a very important issue to improve the earthquake resistance and wind resistance of buildings. Prior art includes vibration-damping structures. Please refer to Figure 1, which shows a schematic diagram of an example of a conventional vibration-damping structure.

[0003] In the prior art, a building structure 91 has multiple vibration control structures 92 inside. The vibration control structures 92 may be hydraulic dampers, installed between beams and columns on each floor. When an earthquake occurs, the fluid in the hydraulic cylinders of the vibration control structures 92 flows at a certain speed, creating a compression effect, which suppresses the force of the shaking through resistance. This allows partial vibration energy to be dissipated, reducing the vibration amplitude of the building structure 91. Summary of the Invention [Problem to be solved by the invention]

[0004] However, the manufacturing costs of prior art hydraulic dampers are very high, possible vibration directions must be taken into consideration when installing them, and the design of the building structure 91 cannot be specially designed.

[0005] Therefore, as a result of extensive research, the inventors have discovered that the above object can be achieved by adopting a novel vibration-damping structure for a wall panel frame, and have thus completed the present invention.

[0006] The present invention was made in consideration of the above circumstances, and aims to solve the above problems. That is, the main object of the present invention is to provide a vibration-damping structure for a wall panel frame that generates an in-plane frictional force due to earthquake energy, generates an out-of-plane reverse inertial force, and generates an out-of-plane restoring force due to wind vibration that causes gravity to properly shake the structure back, thereby reducing the amplitude of vibration caused by earthquakes or wind using these three forces. [Means for solving the problem]

[0007] To achieve the above-mentioned object, one embodiment of the present invention provides a wall panel frame vibration control structure for use in a building structure, the building structure having at least one vertical structure and at least one horizontal structure. The wall panel frame vibration control structure includes an outer frame, an inner frame, metal bars, and a plurality of steel cables. The outer frame is installed within a space defined by the at least one vertical structure and at least one horizontal structure. The inner frame is installed inside the outer frame. The metal bars are installed between the outer frame and the inner frame. The plurality of steel cables are used to connect the metal bars to the at least one vertical structure or the at least one horizontal structure. In this manner, when the building structure is subjected to earthquake vibrations, the metal bars contact the outer or inner frame to generate an in-plane frictional force, and the metal bars swing to generate an out-of-plane counter-inertial force. Furthermore, the metal bars swing out-of-plane due to wind vibrations, generating a restoring force that restores the correct swing due to gravity. These three forces reduce the amplitude of vibrations caused by earthquakes or wind, respectively. Depending on the functionality required, multiple horizontal or vertical inner frames, or multiple inner frames with an inclination angle, are arranged, and combined with a wall panel frame vibration control structure consisting of multiple metal bars and multiple steel cables between the frames. The aforementioned functionality-enhancing members generate a large friction surface in-plane when an earthquake occurs, and the increased vibration of the metal bars out-of-plane generates an even larger reverse inertia force. In addition, due to the increased functionality, when the metal bars are shaken by wind, a large gravitational force is generated out-of-plane to correctly shake them back, and these three forces significantly reduce the vibration of the building structure caused by earthquakes or wind.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Note that the present disclosure is not limited to the following embodiments and may take various forms as long as they fall within the technical scope of the present disclosure.

[0010] 2A and 2B are schematic diagrams showing the vibration-damping structure for a wall panel frame according to a first embodiment of the present invention, respectively, and are schematic diagrams showing the vibration-damping structure for a wall panel frame according to the first embodiment of the present invention applied to a building structure.

[0011] In a first embodiment of the present invention, a wall-frame vibration-damping structure 10a is used within the elevation frame of an architectural structure 1, which includes at least one vertical structure 2 and at least one horizontal structure 3. The vertical structure 2 is a column or wall, and the horizontal structure 3 is a beam or floorboard. The vibration-damping structure includes an outer frame 21, an inner frame 22a, a metal bar 31a, and a plurality of steel cables 32. The outer frame 21 and the inner frame 22a are both installed within a space defined by the at least one vertical structure 2 and the at least one horizontal structure 3, and are installed, for example, on a wall or floorboard. The inner frame 22a is installed inside the outer frame 21 and, like the outer frame 21, is rectangular, although the present invention is not limited thereto. A single metal bar 31a is installed between the outer frame 21 and the inner frame 22a, and the metal bar 31a is in slight contact with the outer frame 21 and the inner frame 22a or maintains a gap of several millimeters therebetween. A plurality of steel cables 32 secure the metal bar 31a to at least one of the vertical structures 2 or at least one of the horizontal structures 3. The present invention does not limit the number of steel cables 32 connected to the metal bar 31a. The horizontally installed steel cables 32 are connected to the vertical structures 2 on both sides, and the vertically installed steel cables 32 are connected to the upper and lower horizontal structures 3. The steel cables 32 are connected to the metal bar 31a, and the plurality of steel cables 32 do not come into contact with each other.

[0012] The interior of the architectural structure 1 in FIG. 2B is divided into multiple stories and multiple compartments by vertical structures 2 and horizontal structures 3, but the present invention does not limit the number of such structures. Therefore, the architectural structure 1 has multiple wall-frame vibration-damping structures 10a, which are installed between the beams and columns or between the walls and floors of each story. When an earthquake occurs, the wall-frame vibration-damping structures 10a are deformed under pressure in-plane and come into contact with the outer frame 21 or inner frame 22a, generating friction. Furthermore, after the architectural structure 1 vibrates, the metal bars 31a swing out-of-plane, generating a counter inertial force. When wind damage occurs, the out-of-plane swing of the metal bars 31a generates a restoring force that returns the structure to its normal position under gravity. These three forces respectively dissipate earthquake energy or damp wind force. The two types of forces, friction and inertia, occur independently within the three-dimensional architectural structure 1 and jointly resist, suppressing the forces acting during earthquake vibration. The gravity-induced restoring force, which occurs when the three-dimensional architectural structure 1 sways out-of-plane due to wind damage, is independently provided to the three-dimensional architectural structure 1, reducing the forces acting during wind vibration. In this way, the wall panel frame vibration control structure 10a corresponds to a combination of a multi-faceted friction damper and an intelligent multi-mode tuned mass damper, partially dissipating earthquake energy. In addition, with regard to wind resistance, the device independently provides the gravity-induced restoring force through the intelligent multi-mode tuned mass, reducing the forces acting during wind vibration. These three forces respectively reduce the amplitude of earthquake and wind vibration of the architectural structure 1.

[0013] 3A is a cross-sectional view showing a vibration control structure according to a first embodiment of the present invention, which is applied to vibration control functions for earthquakes and wind.

[0014] In the first embodiment of the present invention, the metal bars 31a each have a rectangular cross section, and the steel cable 32 is connected to the center of the cross section of the metal bar 31a. The outer frame 21 and the inner frame 22a contact the metal bars 31a via the stainless steel layer 23. In this manner, when the architectural structure 1 vibrates, the metal bars 31a come into contact with the outer frame 21 or the inner frame 22a, generating in-plane frictional forces, or the swinging of the metal bars 31a generates out-of-plane counter-inertial forces. Furthermore, the swinging of the metal bars 31a due to wind sway generates out-of-plane restoring forces that properly return the structure to its original position due to gravity. The vibration control structure 10a corresponds to an in-plane friction type and out-of-plane tuning mass damper, and the generated multi-faceted frictional forces and multi-mode counter-inertial forces together reduce the seismic vibration amplitude of the architectural structure 1. Furthermore, the out-of-plane restoring forces that properly return the structure to its original position due to gravity caused by wind swaying also suppress and reduce the degree of wind-induced swaying of the architectural structure 1.

[0015] 3B is a cross-sectional view showing a vibration control structure according to a second embodiment of the present invention, which is applied to vibration control functions for earthquakes and wind.

[0016] In the second embodiment of the present invention, when the cross sections of the multiple metal bars 31b of the vibration control structure 10b are circular, the metal bars 31b come into contact with the outer frame 21 or the inner frame 22a, generating a frictional force within the plane, the metal bars 31b oscillate out of the plane, generating a reverse inertial force, and the metal bars 31b oscillate out of the plane when oscillated by the wind, generating a restoring force that swings them back to the correct position due to gravity, and these three forces respectively achieve vibration control functions against earthquake forces and wind forces.

[0017] Different architectural structure 1 designs require different designs of vibration-damping structure 10. Fig. 3C is a cross-sectional view showing a vibration-damping structure according to a third embodiment of the present invention. Fig. 3D is a cross-sectional view showing a vibration-damping structure according to a fourth embodiment of the present invention. Figs. 3C and 3D are applied to earthquake vibration control and torque resistance.

[0018] In the third and fourth embodiments of the present invention, the cross sections of the metal bars 31c of the vibration-damping structure 10c and the metal bars 31d of the vibration-damping structure 10d are not rectangular or circular but have a special design. The cross section of the metal bar 31c resembles a bell shape, and the cross section of the metal bar 31d resembles a pentagon, with one side having a larger contact area with the outer frame 21 or the inner frame 22a than the other side, and the shapes of the contact surfaces between the metal bars 31c, 31d and the outer frame 21 and the inner frame 22a are compatible with each other. Alternatively, in other embodiments, the cross sections of the metal bars may resemble the tip of a crayon. Because the contact area between metal bar 31c and inner frame 22a is significantly larger than that with outer frame 21, the frictional force generated between metal bar 31c and inner frame 22a acts as a force in the direction of contact with the inclined surface. This inclined frictional force and the axial component of the contact angle jointly resist the torque transmitted to the upper and lower floors. This vibration damping device has an energy-dissipating effect that reduces the torque transmitted to the upper and lower floors. It also reduces the torsional angle caused by eccentricity between the upper and lower floors due to the quality and structural rigidity of the upper and lower floors, improving the comfort of using the building. Therefore, both vibration damping structures 10c and 10d are torque-resistant structures and are suitable for placement at the four corners of the building structure 1. The above-mentioned vibration damping structures 10a-10d may be mixed and installed at different floor locations of the building structure shown in Figure 2B based on the torque resistance requirements, and may be used in the following fifth to tenth embodiments.

[0019] Next, Fig. 4 is a cross-sectional view showing a vibration-damping structure for a wall panel frame according to a fifth embodiment of the present invention, which is applied to vibration-damping functions against earthquakes and wind.

[0020] In the fifth embodiment of the present invention, the wall panel frame vibration damping structure 10e includes a plurality of inner frames 22b, each of which has a triangular shape, and the partial metal bars 31a-31d and the steel cables 32 are fitted to the shape of the inner frames 22b and installed in a diagonal direction.

[0021] Next, Fig. 5 is a cross-sectional view showing a vibration control structure for a wall panel frame according to a sixth embodiment of the present invention, which is applied to vibration control functions for earthquakes and wind.

[0022] In the sixth embodiment of the present invention, the inner frame 22c of the wall panel frame vibration control structure 10f has a plurality of rectangular shapes, and therefore the metal bars 31a to 31d and steel cables 32 are also installed in quantities that match the number of inner frames 22c.

[0023] Next, Fig. 6 is a cross-sectional view showing a vibration-damping structure for a wall panel frame according to a seventh embodiment of the present invention, which is applied to vibration-damping functions against earthquakes and wind.

[0024] In the seventh embodiment of the present invention, the wall panel frame vibration control structure 10g has a plurality of trapezoidal inner frames 22d, and the metal bars 31a to 31d and steel cables 32 are similarly installed to conform to the shape and number of the plurality of inner frames 22d.

[0025] Next, Fig. 7 is a cross-sectional view showing a wall panel frame vibration control structure according to an eighth embodiment of the present invention, which is applied to vibration control functions for earthquakes and wind.

[0026] In the eighth embodiment of the present invention, a wall panel frame vibration control structure 10h has multiple metal bars 31a-31d between the outer frame 21 and inner frame 22a on each side, rather than the implementation in which only one metal bar 31a-31d is installed on one side as in Figure 2a. In the eighth embodiment, the wall panel frame vibration control structure 10h generates a frictional force in-plane, a counter-inertial force out-of-plane, and a restoring force out-of-plane that causes the structure to return to its normal position due to gravity when rocked by wind, and these three forces respectively achieve vibration control functions against earthquakes and wind.

[0027] Next, Fig. 8 is a cross-sectional view showing a wall panel frame vibration control structure according to a ninth embodiment of the present invention, which is applied to vibration control functions for earthquakes and wind.

[0028] In the ninth embodiment of the present invention, only one metal bar 31a and multiple steel cables 32 are provided between the outer frame 21 and multiple trapezoidal inner frames 22d or multiple rectangular inner frames 22e on each side of the wall panel frame vibration control structure 10i. Unlike the embodiment shown in FIG. 2a, which has only one metal bar 31a-31d on one side, the wall panel frame 10h uses multiple metal bars 31a and multiple steel cables 32 corresponding to the outer frame, inner frame, multiple inner frames 22d, and inner frame 22e. In this ninth embodiment, the wall panel frame vibration control structure 10i generates an in-plane frictional force when an earthquake occurs, an out-of-plane reverse inertial force, and an out-of-plane restoring force that restores the structure to its normal position due to gravity when the structure is shaken by wind. These three forces respectively achieve vibration control functions against earthquakes and wind.

[0029] Finally, Fig. 9 is a cross-sectional view showing a vibration-damping structure for a wall panel frame according to a tenth embodiment of the present invention, which is applied to vibration-damping functions for earthquakes and wind.

[0030] In a tenth embodiment of the present invention, metal bars 31a-31d are provided between outer frame 21 of wall panel frame vibration control structure 10j and inner frames 22f on three sides, inner frame 22f having a door frame shape with partial members joined to horizontal structure 3 or vertical structure 2, and multiple steel cables are also installed to fit metal bar 31a. In this tenth embodiment, wall panel frame vibration control structure 10j generates a frictional force in-plane, generates a reverse inertial force out-of-plane, and further generates a restoring force out-of-plane that causes the structure to be properly swayed back by gravity when rocked by wind, and these three forces respectively achieve vibration control functions against earthquakes and wind.

[0031] With the above-described structure, the metal bars 31a-31d and steel cables 32 of the wall panel frame vibration control structures 10a-10j of the present invention may be installed horizontally, vertically, inclined, or even in an arc. Therefore, when the architectural structure 1 vibrates, the wall panel frame vibration control structures 10a-10j not only control the vibration through out-of-plane counter-inertial forces, but also provide effective in-plane frictional forces, reducing the amplitude and torsional angle of earthquake vibrations. Furthermore, wind vibrations generate a restoring force that restores the proper swing back due to gravity out-of-plane, thereby reducing the vibration. Furthermore, the wall panel frame vibration control structures 10a-10j can be flexibly designed and positioned to fit the shape or vibration direction of the architectural structure 1, effectively overcoming the shortcomings of the prior art.

[0032] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
