Description

Technical Field

[0001] The utility model relates to the field of energy dissipation and shock absorption of building structures, in particular to a novel viscoelastic damping wall. Background Art

[0002] Viscoelastic damping walls can effectively reduce wind vibration and seismic response of building structures. They can add stiffness to the structure, reduce the displacement response of the structure, absorb seismic energy, and increase structural damping. A new type of viscoelastic damping material composite steel plate wall is disclosed in the Chinese utility model patent with announcement number CN214994864U, which mainly includes upper and lower end plates, viscoelastic damping materials, steel splints, inner steel plates and outer steel plates. The whole is composed of steel plates to provide support for the structure. The upper and lower ends of the inner and outer steel plates are connected to the upper and lower plates, and the connection between the steel plates and the upper and lower plates is welded to improve the overall integrity of the structure. In the above structure, the upper steel plate contacts the top of the inner steel plate and the outer steel plate, and the bottom of the steel splint contacts the bottom end plate, which makes the viscoelastic damping wall only consume the external force parallel to the viscoelastic damping wall when shearing hysteresis energy consumption, and when the viscoelastic damping wall is subjected to a force perpendicular to the damping wall, it cannot consume energy through the shear friction between the inner steel plate and the viscoelastic damping material. To this end, we designed a new type of viscoelastic damping wall. Utility Model Content

[0003] In order to solve the technical problem that the viscoelastic damping wall cannot dissipate the force perpendicular to the damping wall through the shear friction between the inner steel plate and the viscoelastic damping material, the utility model provides a novel viscoelastic damping wall.

[0004] The utility model is implemented by the following technical scheme: a novel viscoelastic damping wall, comprising two symmetrically arranged outer steel plates on the left and right, side steel plates are respectively welded at the front and rear ends between the two outer steel plates, mounting base plates are welded at the bottom ends of the outer steel plates and the side steel plates, a storage cavity is formed between the outer steel plates, the side steel plates and the mounting base plate, a resistance plate is suspended in the storage cavity, and multiple groups of evenly distributed resistance parts are welded to the left and right side surfaces of the resistance plate, the resistance parts do not contact the inner walls of the outer steel plates, and the space between the storage cavity and the resistance plates and the resistance parts is filled with viscous fluid.

[0005] As a further improvement of the above solution, a mounting top plate is welded to the top of the resistance plate, and a plurality of linearly distributed fixing holes are provided on the mounting top plate and the mounting bottom plate.

[0006] As a further improvement of the above scheme, the resistance part includes two connecting steel plates, which are distributed up and down and welded to the resistance plate. A connecting hole is opened on the connecting steel plate, and bolts are passed through the connecting holes up and down. Nuts are threaded on the bolts to facilitate the installation and fixation of the viscoelastic damping wall. Tightening the nuts between the two connecting steel plates can cause a certain deformation of the connecting steel plates, thereby changing the resistance between the resistance part and the mounting slide plate, making its shear friction energy consumption greater.

[0007] As a further improvement of the above-mentioned solution, two symmetrically distributed guide grooves are provided on the inner surface of the outer steel plate, and an installation slide plate is provided in the guide groove for sliding up and down. The installation slide plate is inserted into the gap between the two connecting steel plates. There is a certain resistance between the installation slide plate and the resistance part, thereby increasing the resistance between the resistance part and the installation slide plate.

[0008] As a further improvement of the above solution, the mounting slide plate is slid forward and backward and is placed between two connecting steel plates, and the length of the mounting slide plate is greater than the length of the connecting steel plates. The resistance part will not easily lose contact with the mounting slide plate when it moves horizontally forward and backward.

[0009] As a further improvement of the above scheme, the inward side of the mounting slide plate does not contact the bolt, and there is a spacing of 1-3 cm between the two. The end of the connecting steel plate away from the resistance plate does not contact the inner wall of the outer steel plate, and there is a spacing of 3-5 cm between the two. The resistance plate has a certain margin when moving forward and backward and left and right, which facilitates its movement, and can thus dissipate energy by shearing friction under the action of viscous fluid.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model suspends the resistance plate in the storage cavity through the viscous fluid, and the upper end of the resistance plate is above the outer steel plate, and the front, back, left and right sides of the resistance plate are not in contact with the outer steel plate and the side steel plate. The resistance plate can move forward and backward and up and down. When it is subjected to horizontal and vertical vibrations, it can produce a certain displacement so that the fluid in the viscous damping wall is sheared, and the energy input by the earthquake is dissipated;

[0012] 2. By setting resistance parts on the front and rear sides of the resistance plate, and setting an up and down sliding mounting slide plate on the inner side of the outer steel plate, the mounting slide plate and the resistance part are in front and back sliding contact, which increases the overall area of ​​the resistance plate, making it more subjected to greater force when moving front and back, left and right, and up and down, and the shear friction energy consumption is also greater.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example:

[0021] Please combine Figure 1-Figure 4 A novel viscoelastic damping wall of the present embodiment comprises two symmetrically arranged outer steel plates 1 on the left and right, side steel plates 2 are welded at the front and rear ends of the two outer steel plates 1 respectively, mounting base plates 3 are welded at the bottom ends of the outer steel plates 1 and the side steel plates 2, a storage cavity 6 is formed between the outer steel plates 1, the side steel plates 2 and the mounting base plates 3, a resistance plate 4 is suspended in the storage cavity 6, and multiple groups of evenly distributed resistance parts 8 are welded on the left and right side surfaces of the resistance plate 4, the resistance part 8 does not contact the inner wall of the outer steel plate 1, and the space between the storage cavity 6 and the resistance plate 4 and the resistance part 8 is filled with a viscous fluid 7.

[0022] A mounting top plate 5 is welded to the top of the resistance plate 4 , and a plurality of linearly distributed fixing holes are provided on the mounting top plate 5 and the mounting bottom plate 3 .

[0023] The resistance part 8 includes two connecting steel plates 81, which are distributed up and down and welded to the resistance plate 4. A connecting hole is opened on the connecting steel plate 81, and bolts 82 are passed through the connecting holes up and down. Nuts are threaded on the bolts 82 to facilitate the installation and fixation of the viscoelastic damping wall. Tightening the nuts between the two connecting steel plates 81 can cause the connecting steel plates 81 to undergo a certain deformation, thereby changing the resistance between the resistance part 8 and the mounting slide plate 11, causing its shear friction energy consumption to be greater.

[0024] Two symmetrically distributed guide grooves 12 are provided on the inner side surface of the outer steel plate 1, and an installation slide plate 11 is arranged to slide up and down in the guide groove 12. The installation slide plate 11 is inserted into the gap between the two connecting steel plates 81. There is a certain resistance between the installation slide plate 11 and the resistance part 8, which increases the resistance between the resistance part 8 and the installation slide plate 11.

[0025] The mounting slide plate 11 slides forward and backward and is placed between the two connecting steel plates 81 . The length of the mounting slide plate 11 is greater than the length of the connecting steel plates 81 . The resistance part 8 will not easily break away from the contact with the mounting slide plate 11 when it moves horizontally forward and backward.

[0026] The inner side of the mounting slide plate 11 does not contact the bolt 82, and there is a distance of 1-3 cm between the two. The end of the connecting steel plate 81 away from the resistance plate 4 does not contact the inner wall of the outer steel plate 1, and there is a distance of 3-5 cm between the two. The resistance plate 4 has a certain margin when moving forward and backward and left and right, which is convenient for its movement, and can dissipate energy by shear friction under the action of the viscous fluid 7.

[0027] The implementation principle of a novel viscoelastic damping wall in the embodiment of the present application is as follows: a storage cavity 6 formed between two outer steel plates 1, two side steel plates 2 and a mounting bottom plate 3 is filled with a viscous fluid 7, a resistance plate 4 is suspended in the storage cavity 6 by the viscous fluid 7, the upper end of the resistance plate 4 is above the outer steel plate 1 and the two have a certain height, and the front, back, left and right sides of the resistance plate 4 are not in contact with the outer steel plate 1 and the side steel plate 2, so that the resistance plate 4 can move forward and backward and move up and down, and when it is subjected to horizontal and vertical vibrations, it can generate a certain displacement to cause the fluid in the viscous damping wall to be sheared, and the energy input by the earthquake is dissipated;

[0028] By arranging a resistance part 8 on the front and rear sides of the resistance plate 4, and arranging an up and down sliding mounting slide 11 on the inner side of the outer steel plate 1, the mounting slide 11 is in front and back sliding contact with the resistance part 8, thereby increasing the overall area of ​​the resistance plate 4, making it subject to greater force when moving front and back, left and right, and up and down, and the shear friction energy consumption is also greater.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
