Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a sealing structure for a viscous damper installation node. Background Technology

[0002] In the field of building structures, seismic protection is the key to ensuring building safety and stability. How to effectively reduce the vibration of buildings under wind loads, earthquakes, etc., and improve the seismic resistance of building structures is an important issue in building design.

[0003] In existing technologies, non-load-bearing components in structures (such as supports and shear walls) are often designed as upper and lower cantilever walls spaced vertically, with viscous dampers installed between them to dissipate the structure's vibrational energy through the resulting energy dissipation. Under wind loads and minor earthquakes, the dampers are in an elastic state, and the lateral stiffness of the structural system is sufficient to meet normal service requirements.

[0004] After the damper is installed, the opening between the upper and lower cantilever walls needs to be sealed. For example, a viscous damper wall sealing structure with patent number CN221001491U uses 9.5mm thick gypsum board for sealing the inner side of the building wall and 2.0mm thick patterned aluminum alloy plate for sealing the outer side of the outer wall. This solves the difficulties of on-site construction and improves the waterproof performance after the opening is sealed.

[0005] However, using rigid materials such as gypsum board or aluminum alloy plate to fix the upper and lower cantilever walls will affect the relative movement between the upper and lower cantilever walls, thereby affecting the damping movement of the dampers and reducing the damping capacity of the joints.

[0006] Therefore, it is necessary to study a sealing structure for the mounting node of a viscous damper. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a sealing structure for the installation node of a viscous damper, which can effectively solve the problem that using rigid plates to fix the upper and lower cantilever walls will affect the damper's shock absorption movement.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A viscous damper installation node sealing structure includes an upper cantilever wall and a lower cantilever wall that are fixedly connected to the upper and lower frame beams respectively, with a gap between the upper and lower cantilever walls, and a viscous damper is installed in the gap; it also includes an inner lining plate, a wire mesh layer and a mortar layer;

[0010] The inner lining plate is set between the upper cantilever wall and the lower cantilever wall, and is symmetrically distributed on both sides of the viscous damper. Rock wool is filled between the inner lining plate and the damper.

[0011] The inner lining plate includes an upper lining plate, a lower lining plate, and a sliding groove plate;

[0012] The lower end of the lower liner plate is fixedly connected to the lower cantilever wall;

[0013] The slide plate is fixed to the inner surface of the upper end of the lower liner plate and is spaced apart from the inner surface of the lower liner plate to form an upper-opening U-shaped slide plate.

[0014] The upper end of the upper liner is fixedly connected to the upper cantilever wall, and the lower end of the upper liner is slidably disposed in the groove.

[0015] The wire mesh layer is fixed to the outer surface of the inner lining plate, and the outer surface of the wire mesh layer is coated with a mortar layer.

[0016] Furthermore, the viscous damper is horizontally positioned, with its two ends hinged to the upper cantilever wall and the lower cantilever wall, respectively.

[0017] Furthermore, embedded plates are pre-embedded and fixed on the surfaces facing each other of the upper and lower cantilever walls, and hinge seats are fixedly connected to each embedded plate. The end of the viscous damper is hinged to the embedded plate.

[0018] Furthermore, both the upper and lower ends of the inner lining plate are fixedly connected to the embedded plate by multiple connecting angle steels.

[0019] Furthermore, one flange of the connecting angle steel is fixedly connected to the inner surface of the inner lining plate, and the other flange is fixedly connected to the embedded plate.

[0020] Furthermore, both the upper and lower cantilever walls are provided with fixedly connected vertical and horizontal reinforcing bars.

[0021] The vertical reinforcement extends into the frame beam and is fixedly connected to the frame beam.

[0022] Furthermore, a flexible waterproof layer is provided between the inner lining plate and the wire mesh layer.

[0023] The beneficial effects of the above technical solution are:

[0024] This invention divides the inner lining plate into an upper lining plate, a lower lining plate, and a sliding groove plate. The upper end of the upper lining plate is fixedly connected to the upper cantilever wall, and the lower end of the upper lining plate is slidably disposed in the sliding groove, allowing the upper lining plate to slide along the length of the sliding groove. This enables the inner lining plate to adapt to the horizontal relative movement of the upper and lower cantilever walls along the length of the wall. The end of the upper lining plate is spaced from the bottom of the U-shaped sliding groove, providing displacement space for the vertical movement of the upper lining plate. This enables the inner lining plate to adapt to the vertical relative movement of the upper and lower cantilever walls along the height of the wall. In summary, in addition to providing a stable fixed support foundation and waterproofing for the internal rock wool and external mortar layer, the inner lining plate can also adapt to the relative movement between the upper and lower cantilever walls without affecting the damping motion of the viscous damper, ensuring the energy dissipation efficiency of the viscous damper.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] This embodiment aims to provide a sealing structure for the installation node of the viscous damper 4, which is mainly used for the construction of cantilever walls for internal wall dampers. It addresses the problem that using rigid plates to fix the upper and lower cantilever walls 3 will affect the damper's vibration reduction movement.

[0035] A sealing structure for mounting nodes of a viscous damper 4, such as Figure 1 and Figure 2 The structure includes an upper cantilever wall 2 and a lower cantilever wall 3, which are respectively fixedly connected to the upper and lower frame beams 1. Frame columns 14 are fixedly connected between the upper and lower frame beams 1. Both the upper cantilever wall 2 and the lower cantilever wall 3 are non-load-bearing building structures, which are vibration-damping structural walls based on the existing building structure. Vertical reinforcing bars 201 and horizontal reinforcing bars 202 are pre-embedded in both the upper cantilever wall 2 and the lower cantilever wall 3 and are fixedly connected to each other perpendicularly. The vertical reinforcing bars 201 extend into the frame beams 1 and are fixedly connected to the frame beams 1. Specifically, the vertical reinforcing bars 201 can be pre-embedded in the frame beams 1 to improve the reliability of the fixed connection between the upper cantilever wall 2 and the lower cantilever wall 3 and the frame beams 1.

[0036] A horizontal gap is maintained between the upper cantilever wall 2 and the lower cantilever wall 3, and a viscous damper 4 is installed in the gap; specifically, such as Figure 1-3 ,as well as Figure 5 and Figure 6 Both the upper cantilever wall 2 and the lower cantilever wall 3 have embedded plates 9 fixedly embedded on their opposite surfaces. Hinges 10 are fixedly connected to each embedded plate 9. A viscous damper 4 is horizontally positioned, with its two ends hinged to the upper cantilever wall 2 and the lower cantilever wall 3 respectively. The ends of the viscous damper 4 are hinged to the embedded plates 9 via pins. When the upper cantilever wall 2 and the lower cantilever wall 3 move relative to each other, the two ends of the viscous damper 4 also move accordingly, thus forming damping and energy dissipation. The specific structure and principle of the viscous damper 4 are based on existing technology and will not be elaborated here.

[0037] The innovation of this application lies in the inclusion of an inner lining plate 5, a wire mesh layer 6, and a mortar layer 7. The inner lining plate 5 is disposed between the upper cantilever wall 2 and the lower cantilever wall 3, and is symmetrically distributed on both sides of the damper to seal both sides of the gap between the upper cantilever wall 2 and the lower cantilever wall 3. Both the upper and lower ends of the inner lining plate 5 are fixedly connected to the embedded plate 9 by multiple connecting angle steels 11. One flange of the connecting angle steel 11 is bolted to the inner surface of the inner lining plate 5, and the other flange is fixedly connected to the embedded plate 9.

[0038] Rock wool 8 is filled between the inner lining plate 5 and the viscous damper 4 to avoid affecting the operation of the viscous damper 4 and to improve the insulation of the seal. Specifically, such as... Figure 4The inner lining plate 5 is made of aluminum alloy profile plate. The inner lining plate 5 includes an upper lining plate 501, a lower lining plate 502 and a sliding plate 503. The lower end of the lower lining plate 502 is fixedly connected to the lower cantilever wall 3. The sliding plate 503 is L-shaped and is riveted to the inner surface of the upper end of the lower lining plate 502, and is spaced from the inner surface of the lower lining plate 502 to form an upper-opening U-shaped sliding groove 504. The upper end of the upper liner 501 is fixedly connected to the upper cantilever wall 2, and the lower end of the upper liner 501 is slidably disposed in the slide groove 504, so that the upper liner 501 can slide along the length direction of the slide groove 504, and the inner liner 5 can adapt to the horizontal relative movement of the upper cantilever wall 2 and the lower cantilever wall 3 along the length direction of the wall; the end of the upper liner 501 is spaced from the bottom of the U-shaped slide groove 504, providing displacement space for the vertical movement of the upper liner 501, and the inner liner 5 can adapt to the vertical relative movement of the upper cantilever wall 2 and the lower cantilever wall 3 along the height direction of the wall.

[0039] In this embodiment, the inner lining plate 5 can provide a stable fixed support foundation for the internal rock wool 8 and the external mortar layer 7, provide a certain waterproof effect, and can also adapt to the relative movement between the upper cantilever wall 2 and the lower cantilever wall 3 without affecting the shock absorption movement of the viscous damper 4.

[0040] The wire mesh layer 6 is fixed to the outer surface of the inner lining plate 5 to facilitate the adhesion of the mortar layer 7. The wire mesh layer 6 is a flexible layer and will not affect the damping movement of the viscous damper 4. The outer surface of the wire mesh layer 6 is coated with the mortar layer 7, which is continuously laid and connected on the upper cantilever wall 2 and the lower cantilever wall 3 to form a continuous wall surface layer.

[0041] Furthermore, a flexible waterproof layer 15 is laid between the inner lining board 5 and the wire mesh layer 6. The flexible waterproof layer 15 uses waterproof membrane, waterproof roll material, etc., to improve waterproofing.

[0042] In addition, such as Figure 1 In this embodiment, infill walls 12 are provided on both the left and right sides of the upper and lower cantilever walls. The infill walls 12 can be masonry walls, lightweight concrete walls, partition walls, etc. Flexible infill layers 13 are provided on the upper and lower cantilever walls and the infill walls 12. The flexible infill layers 13 can be filled with foam, etc., to ensure that the upper and lower cantilever walls can move horizontally.
