Description
Technical Field
[0001] This utility model relates to the field of building keel technology, and in particular to a high-elasticity vibration-damping partition wall keel structure. Background Technology
[0002] In civil buildings, partition walls are a critical structural component, and their design must strictly adhere to multiple standards to ensure the overall performance of the building and the safety and comfort of its occupants. Fire resistance is paramount; partition walls must effectively prevent the spread of fire within a specified timeframe, meeting the corresponding fire resistance standards. Secondly, sound insulation is equally important, especially in private spaces such as bedrooms and bathrooms, which require excellent sound insulation to maintain a quiet living environment. In terms of load-bearing capacity, partition walls must be able to withstand the loads of the area, ensuring the building's safety and stability in extreme conditions such as earthquakes.
[0003] The existing sound insulation and vibration reduction wall has an internal structure with a light steel keel in the middle, filled with sound insulation rock wool, and double-layer gypsum board installed on the sides. The lower end of the keel is connected to the ground, and the upper end extends into the ceiling and is fixed to the building floor slab. Buffer pads are provided above and below the single-layer keel to avoid the formation of sound bridges, which would cause sound waves to propagate outward.
[0004] To improve sound insulation, existing technologies incorporate elastic panels in the keel structure. However, this creates a gap between the sound insulation panel in the middle of the keel and the rock wool. This air gap is particularly weak at blocking low-frequency sounds and is prone to resonance, thus reducing sound insulation effectiveness. Furthermore, because the elastic panel is directly connected to the middle of the keel, the existing keel structure suffers from poor elasticity and vibration damping. Additionally, the elastic panel's placement within the gap between the sound insulation panel and the rock wool makes the keel susceptible to deformation under stress, leading to synchronized deformation across different layers of the partition wall and compromising structural stability. Utility Model Content
[0005] In view of this, the present invention aims to propose a high-elasticity vibration-damping partition wall keel structure, which can increase the vibration reduction and sound insulation effect of the partition wall, reduce the processing difficulty, and improve the stability of the wall structure.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0007] A high-elasticity vibration-damping partition wall keel structure includes a support part located in the middle, extension parts connected to both ends of the support part, and a bending part vertically connected to the outer end of the extension part.
[0008] The support includes an upward-opening U-shaped plate and a connecting part that is connected to the bottom end of the U-shaped plate and opens downward.
[0009] The extension is connected to one side of the connecting part, and the extension is provided with an elastic part that arches toward the opening of the U-shaped plate. The elastic part, the connecting part, and part of the extension form a first elastic space.
[0010] The arching direction of the elastic part is the same as the extension direction of the bent part;
[0011] The space between the bending part and the supporting part is used to place fireproof and soundproof rock wool board;
[0012] The elastic portion and the extension portion respectively abut against the two spliced fireproof and soundproof rock wool boards.
[0013] Furthermore, the elastic part is formed into an "n" shape with a downward opening;
[0014] The elastic portion encloses and forms a second elastic space;
[0015] The elastic portion is bent and shaped on the extension portion.
[0016] Furthermore, the elastic portion divides the extension into a first extension segment and a second extension segment;
[0017] The elastic part includes an arc segment and vertical segments respectively connected to both sides of the arc segment;
[0018] The first extension segment is connected to one of the vertical segments with a rounded transition, and the second extension segment is connected to the other vertical segment with a rounded transition.
[0019] Furthermore, the U-shaped plate includes a base plate and side plates connected to both sides of the base plate; the side plate near the connecting part is disposed between the first elastic space and the second elastic space;
[0020] The connecting part includes a support plate that is connected to the side plate, and the upper support plate covers and connects to the outside of the side plate.
[0021] Furthermore, the two extensions, elastic portions, and bending portions are symmetrically arranged relative to the support portion;
[0022] The opening width B1 of the U-shaped plate and the opening width B2 of the connecting part are equal in size;
[0023] The openings in the U-shaped plate and the connecting part are used to install sound insulation panels.
[0024] Furthermore, along the extending direction of the bent portion, a plurality of protrusions are provided at intervals;
[0025] The protrusion protrudes toward the support portion, and the protrusion is also formed with a recessed portion for installing the keel nail.
[0026] Furthermore, the end of the bent portion away from the extension portion is provided with a reinforcing plate that bends toward the center, and the reinforcing plate is arranged perpendicular to the bent portion.
[0027] Compared with the prior art, this utility model has the following advantages:
[0028] The high-elasticity vibration-damping partition wall keel structure of this utility model has an elastic part set on the extension part, and the elastic part, the support part and part of the extension part form a first elastic space. During the sound propagation process, the sound resonates and absorbs energy through the two parts of the elastic part and the first elastic space. At the same time, when subjected to lateral force or vibration, the above two parts can generate a certain buffering effect, reduce the impact of vibration on the building structure, and improve the earthquake resistance and shear resistance of the partition wall.
[0029] In addition, there are two spliced fireproof and soundproof rock wool boards in the elastic part and the extension part, that is, the entire space between the outer panel and the sound insulation board is filled with fireproof and soundproof rock wool boards. This avoids the gap between rock wool and sound insulation board in the existing technology. With the same wall thickness, it can effectively absorb and block sound of different frequencies. The increased thickness of the rock wool layer increases the movement distance of sound in the rock wool layer, which effectively improves the sound insulation effect. It can also effectively prevent fire from spreading through the gaps and ensure the fire resistance of the wall. Attached Figure Description

[0044] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0045] This embodiment relates to a high-elasticity vibration-damping partition wall keel structure 1, which, as a whole, is as follows: Figure 1As shown, the keel 1 structure includes a support portion 101 located in the middle, extension portions 102 connected to both ends of the support portion 101, and a bending portion 103 vertically connected to the outer end of the extension portion 102. The support portion 101 includes an upward-opening U-shaped plate 1011 and a connecting portion 1012 connected to the bottom end of the U-shaped plate 1011 and opening downwards. The extension portion 102 is connected to one side of the connecting portion 1012, and the extension portion 102 is provided with an elastic portion 104 arching towards the opening direction of the U-shaped plate 1011. The elastic portion 104, the connecting portion 1012, and part of the extension portion 102 enclose a first elastic space 105. The arching direction of the elastic portion 104 is the same as the extension direction of the bending portion 103. The space between the bending portion 103 and the support portion 101 is used to place fireproof and soundproof rock wool boards 3. The elastic portion 104 and the extension portion 102 respectively abut against the space between two spliced fireproof and soundproof rock wool boards 3.
[0046] In this embodiment, the high-elasticity vibration-damping partition wall keel 1 structure has an elastic part 104 disposed on the extension part 102, and the elastic part 104, the connecting part 1012 and part of the extension part 102 form a first elastic space 105. During the sound propagation process, the sound resonates and absorbs energy through the two parts, the elastic part 104 and the first elastic space 105. At the same time, when subjected to lateral force or vibration, the two parts can generate a certain buffering effect, reduce the impact of vibration on the building structure, and improve the seismic resistance and shear resistance of the partition wall.
[0047] In addition, there are two spliced fireproof and soundproof rock wool boards 3 in the elastic part 104 and the extension part 102 respectively. That is, the space between the outer panel and the sound insulation board 2 is completely filled with fireproof and soundproof rock wool boards 3, which avoids the situation where there are gaps between rock wool and sound insulation board 2 in the prior art. With the same wall thickness, it can effectively absorb and block sound of different frequencies. By increasing the thickness of the rock wool layer, the movement distance of sound in the rock wool layer is increased, which effectively improves the sound insulation effect. It can also effectively prevent fire from spreading through gaps and ensure the fireproof performance of the wall.
[0048] Based on the above overall introduction, this embodiment presents an exemplary structure of the high-elasticity vibration-damping partition wall keel 1, as follows: Figure 1 and Figure 2 As shown, the partition wall structure used in the keel 1 structure of this embodiment is a double partition wall structure, wherein the middle layer of the partition wall is a sound insulation board 2, and fireproof and sound-insulating rock wool boards 3 are provided on both sides of the sound insulation board 2. The outer layer is provided with a base gypsum board 4 and a surface gypsum board 5 in sequence. The support part 101 is used for the installation of the sound insulation board 2.
[0049] As a preferred embodiment, such as Figure 1As shown, along the extension direction of the bending portion 103, several spaced protrusions 107 are provided. The protrusions 107 bulge towards the support portion 101, and each protrusion 107 also has a recessed portion for installing the keel 1 nail. When the fireproof and soundproof rock wool board 3 is inserted and filled into the space enclosed by the support portion 101, the bending portion 103, and the extension portion 102 of the keel 1, it achieves contact between the fireproof and soundproof rock wool board 3 and the soundproof board 2 and the base gypsum board 4, avoiding gaps. The protrusions 107 serve to position the fireproof and soundproof rock wool board 3, preventing it from shifting in the insertion direction. The keel 1 nails are driven into the recessed portions to further fix the keel 1 to the fireproof rock wool layer, improving the stability of the partition wall.
[0050] As Figure 1 As shown, due to the setting of the elastic part 104, the fireproof and soundproof rock wool board 3 needs to be arranged according to the shape of the keel 1, and the joint ends of the two connected fireproof and soundproof rock wool boards 3 have different shapes.
[0051] In addition, as Figure 1 As shown, the end of the bent portion 103 away from the extension portion 102 is provided with a reinforcing plate 108 that bends towards the center, and the reinforcing plate 108 is arranged perpendicular to the bent portion 103. By setting the reinforcing plate 108, not only can the strength of the bent portion 103 be increased and the overall stress strength of the keel 1 be improved, but the fireproof and soundproof rock wool board 3 can also be further prevented from shifting in the insertion direction.
[0052] Preferably, such as Figure 1 As shown, the elastic portion 104 is formed into an "n" shape with a downward opening, and the elastic portion 104 surrounds and forms a second elastic space 106; the elastic portion 104 is bent and formed on the extension portion 102. The opening of the elastic portion 104 faces upward, and the opening of the first elastic space 105 faces upward, and the two are arranged adjacent to each other, avoiding the defects of poor elasticity and poor vibration reduction caused by the direct connection between the elastic portion 104 and the support portion 101 in the prior art.
[0053] Combination such as Figure 1 and Figure 2 As shown, the arching direction of the elastic part 104 is the same as the extension direction of the bending part 103. This structure is beneficial to improving the structural strength of the keel 1 in the height direction. The adjacent arrangement of the elastic part 104 and the first elastic space 105 can weaken the noise in the propagation path due to multiple reflections and absorptions during the propagation process, so that the sound gradually weakens during the propagation process, and finally achieves a better sound insulation effect.
[0054] like Figures 1 to 3As shown, the elastic portion 104 divides the extension portion 102 into a first extension segment 1021 and a second extension segment 1022. The elastic portion 104 includes an arc segment 1041 and vertical segments 1042 respectively connected to both sides of the arc segment 1041. The first extension segment 1021 is connected to one of its vertical segments 1042 with a rounded corner transition, and the second extension segment 1022 is connected to the other vertical segment 1042 with a rounded corner transition. This arrangement facilitates bending processing and allows the elastic portion 104 to deform and absorb energy.
[0055] In addition, such as Figures 2 to 3 As shown, the spacing between the vertical segments 1042 is L1, and the length of L1 ranges from 5 to 8 mm. The length of L1 can be any value among 5 mm, 6 mm, 7 mm, and 8 mm. This setting ensures the bending effect during the processing of the elastic part 104 and provides a better energy absorption and vibration reduction effect.
[0056] As Figure 2 and Figure 3 As shown, the position of the elastic part 104 in the extension 102 is not limited and can be set according to processing needs, but it is necessary to avoid the keel 1 nail intersecting with the elastic part 104 to reduce the elastic effect of the elastic part 104.
[0057] Furthermore, such as Figures 2 to 3 As shown, the U-shaped plate 1011 includes a base plate 10111 and side plates 10112 connected to both sides of the base plate 10111. The side plate 10112 near the connecting portion 1012 is located between the first elastic space 105 and the second elastic space 106. The connecting portion 1012 includes support plates connected to the side plates 10112 respectively, and the upper support plate covers and connects to the outside of the side plate 10112. By setting the support plate to cover the outside of the side plate 10112, the structural strength of the U-shaped plate 1011 is increased, which facilitates the installation of the sound insulation board 2 and enables the keel 1 structure to be integrally extruded and bent, thereby improving the strength of the keel 1 structure.
[0058] Preferably, such as Figures 1 to 3 As shown, the two extensions 102, the elastic part 104, and the bending part 103 are symmetrically arranged relative to the support part 101. The opening width B1 of the U-shaped plate 1011 and the opening width B2 of the connecting part 1012 are equal in size. The openings of the U-shaped plate 1011 and the connecting part 1012 are used to install the sound insulation panel 2. By setting B1 and B2 to be equal, the specifications of the sound insulation panel 2 are ensured to be the same, improving uniformity and facilitating installation and processing.
[0059] Furthermore, such as Figure 2 and Figure 3As shown, the opening height H1 of the U-shaped plate 1011 and the opening height H2 of the connecting part 1012 are both within the range of 15mm to 18mm. This range can be any value among 15mm, 16mm, 17mm, and 18mm. This design ensures the secure installation of the sound insulation panel 2.
[0060] The high-elasticity vibration-damping partition wall keel 1 structure of this embodiment improves the shortcomings of the existing vibration-damping keel 1, increases the vibration reduction and sound insulation effect of the partition wall, reduces the processing difficulty, and improves the use effect and stability of the partition wall.
[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
