Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0022] Embodiments of this application provide a partition wall keel 100, such as Figures 1-8As shown, it includes: a middle structural part 3 and a first side structural part 1 and a second side structural part 2 located on both sides of the middle structural part 3; wherein, The intermediate structure 3 includes an intermediate plate 31, a first inner connecting plate 32, and a second inner connecting plate 33. The first inner connecting plate 32 is vertically connected to one end of the intermediate plate 31 and forms an L-shaped structure with the intermediate plate 31. The second inner connecting plate 33 is vertically connected to the other end of the intermediate plate 31 and forms a T-shaped structure with the intermediate plate 31. Figure 2 As shown, the two sides of the intermediate plate 31 are respectively equipped with intermediate wall panels 200; wherein, the intermediate wall panel 200 installed on one side of the intermediate plate 31 is limited by the first inner connecting plate 32 and the second inner connecting plate 33; the intermediate wall panel 200 installed on the other side of the intermediate plate 31 is fixed to the second inner connecting plate 33 by fasteners 4.

[0023] The first side structural part 1 includes a first outer connecting plate 11 parallel to the first inner connecting plate 32 and a first connecting structure disposed between the first outer connecting plate 11 and the first inner connecting plate 32; the second side structural part 2 includes a second outer connecting plate 21 parallel to the second inner connecting plate 33 and a second connecting structure disposed between the second outer connecting plate 21 and the second inner connecting plate 33. The first outer connecting plate 11 and the second outer connecting plate 21 are configured to mount the outer wall panel 300.

[0024] In the embodiments of this application, an intermediate wall panel 200 is installed on the intermediate structural part 3 of the partition wall keel 100, and outer wall panels 300 are respectively installed on the first outer connecting plate 11 and the second outer connecting plate 21 on both sides. The three layers of wall panels enable the partition wall to effectively insulate against sound. Furthermore, in this application, the first inner connecting plate 32 is vertically connected to one end of the intermediate plate body 31 and forms an L-shaped structure with the intermediate plate body 31, while the second inner connecting plate 33 is vertically connected to the other end of the intermediate plate body 31 and forms a T-shaped structure with the intermediate plate body 31. Thus, on one side of the intermediate plate body 31, the first inner connecting plate 32, the intermediate plate body 31, and the second inner connecting plate 33 together form a U-shaped structure, and on the other side of the intermediate plate body 31, the intermediate plate body 31 and the second inner connecting plate 33 together form an L-shaped structure. When the intermediate wall panel 200 is installed on one side of the intermediate plate body 31... The end of the intermediate wall panel 200 is inserted into the U-shaped structure. When the intermediate wall panel 200 is installed on one side of the intermediate plate 31, one end of the intermediate wall panel 200 cooperates with the L-shaped structure (the L-shaped structure limits the two adjacent sides of one end of the intermediate wall panel 200) and fixes the intermediate wall panel 200 on the second inner connecting plate 33. For example, the intermediate wall panel 200 can be fixed on the second inner connecting plate 33 by fastener 4 (fastener 4 can be screw). This way of installing the intermediate wall panel 200 makes the construction method of the partition wall more flexible and the construction efficiency higher.

[0025] In some embodiments, an H-shaped structure is used to insert intermediate wall panels (i.e., U-shaped structures are set on both sides of the intermediate panel, and the two U-shaped structures form an H-shaped structure for inserting the intermediate wall panels). The intermediate wall panels 200 are inserted into the U-shaped structures on both sides of the intermediate panel. However, since the intermediate wall panels are inserted into the slots of the H-shaped structure, the partition wall is built by erecting a keel and then inserting an intermediate wall panel, and so on. This method of construction does not allow for the arbitrary removal or installation of any intermediate wall panel. In the solution of this application, one side of the intermediate panel 31 is formed into a U-shaped structure for inserting the intermediate wall panels 200, and the other side is formed into an L-shaped structure. Since the intermediate partition wall 200 is attached to the L-shaped structure, there is no problem of interference from the U-shaped slots during installation. Therefore, the partition wall keel 100 provided in this application has an L-shaped structure on one side of the intermediate panel 31 to install the intermediate wall panels 200. This L-shaped structure facilitates the installation and removal of the intermediate wall panels 200, thereby making the construction of the partition wall more flexible, convenient to install, and improving the construction efficiency of the partition wall.

[0026] Figures 4-6 The example shown is an intermediate wall panel 200 installed between two adjacent partition wall studs 100. The two ends of the intermediate wall panel 200 between the two adjacent partition wall studs 100 can be installed on the L-shaped structure of the partition wall studs 100 at both ends, or they can be inserted into the U-shaped structure of the partition wall studs 100 at both ends, or one end can be installed on the L-shaped structure and the other end can be installed on the U-shaped structure. It can be flexibly set according to the construction needs, thereby improving the construction efficiency.

[0027] In one embodiment, such as Figure 1 As shown, the first connection structure includes a deformable first damping plate 12 connected between the first outer connecting plate 11 and the first inner connecting plate 32; the second connection structure includes a deformable second damping plate 22 connected between the second outer connecting plate 21 and the second inner connecting plate 33.

[0028] Vibration damping plates are installed in both the first and second connecting structures to provide vibration damping and sound insulation. For example, when sound reaches the outer wall panel 300 outside the first outer connecting plate 11, the vibration of the outer wall panel 300 will cause the first vibration damping plate 12 to vibrate and deform. This vibration and deformation of the first vibration damping plate 12 absorbs sound energy, reducing its propagation and thus providing sound insulation. Furthermore, the oscillation of sound between the outer wall panel 300 and the intermediate wall panel 200 also reduces the sound energy transmitted to the other side of the partition wall. Additionally, the space between the outer wall panel 300 and the intermediate wall panel 200 can be filled with cotton 400, which further reduces sound transmission. Therefore, the partition wall keel 100 provided in this application allows for a reduction in the thickness of the partition wall while still meeting sound insulation requirements, thereby reducing the cost of the partition wall.

[0029] exist Figure 1 In the example, the first damping plate 12 is connected to the ends of the first inner connecting plate 32 and the first outer connecting plate 11 facing opposite directions, and the first inner connecting plate 32, the first outer connecting plate 11 and the first damping plate 12 form a Z-shaped structure; the second damping plate 22 is connected to the ends of the second inner connecting plate 33 and the second outer connecting plate 21 facing opposite directions, and the second inner connecting plate 33, the second outer connecting plate 21 and the second damping plate 22 form a Z-shaped structure.

[0030] Furthermore, such as Figure 1 As shown, the first damping plate 12 includes a first adapter plate 121 that is perpendicularly connected to the first inner connecting plate 32, a second adapter plate 122 that is perpendicularly connected to the first outer connecting plate 11, and a first inclined plate 123 that connects the first adapter plate 121 and the second adapter plate 122.

[0031] When sound vibrations are generated, the sound is transmitted to the outer wall panel 300, and the first outer connecting plate 11 transmits the sound vibrations to the first damping plate 12. During the vibration of the first damping plate 12, the first inclined plate 123 will bend and deform relative to the first transition plate 121 and the second transition plate 122 to achieve vibration reduction and energy absorption. Of course, the first inclined plate 123 can also be directly connected to the first inner connecting plate 32 and the first outer connecting plate 11.

[0032] The structure of the second damping plate 22 is the same as that of the first damping plate 12, such as... Figure 1 As shown, the second damping plate 22 includes a third adapter plate 221 that is perpendicularly connected to the second inner connecting plate 33, a fourth adapter plate 222 that is perpendicularly connected to the second outer connecting plate 21, and a second inclined plate 223 that connects the third adapter plate 221 and the fourth adapter plate 222.

[0033] exist Figure 1 In the embodiments, the first connecting structure and the second connecting structure respectively adopt Z-shaped damping plates for vibration reduction and sound insulation. It is understood that the first connecting structure and the second connecting structure can also adopt other forms of structure. They can adopt the same structure, for example, both adopt Z-shaped damping plate structure, or they can be set with different structures. There are no restrictions here.

[0034] like Figure 3 In one embodiment, the first connecting structure includes a first plate 14 connected to the ends of the first inner connecting plate 32 and the first outer connecting plate 11 facing the same direction, and the first inner connecting plate 32, the first plate 14 and the first outer connecting plate 11 are formed into a C-shaped structure; the second connecting structure includes a second plate 24 connected to the ends of the second inner connecting plate 33 and the second outer connecting plate 21 facing the same direction, and the second inner connecting plate 33, the second plate 24 and the second outer connecting plate 21 are formed into a C-shaped structure.

[0035] In one embodiment, the ends of the first outer connecting plate 11 and the second outer connecting plate 21 can be bent to form bent portions, such as... Figure 1 and Figure 3 In this design, the end of the first outer connecting plate 11 is bent to form a first bent portion 13, and the end of the second outer connecting plate 21 is bent to form a second bent portion 23. Since filling cotton 400 is respectively provided between the first outer connecting plate 11 and the first inner connecting plate 32 and between the second outer connecting plate 21 and the second inner connecting plate 33, the bent portions can help install the filling cotton 400 and prevent it from falling out.

[0036] In one embodiment, such as Figure 2 As shown, the end of the second inner connecting plate 33 away from the first inner connecting plate 32 extends beyond the first outer connecting plate 11 by a predetermined distance d in the direction away from the intermediate plate 31. This predetermined distance d can be 10-15 mm, and it is sufficient to allow for easy installation of the fastener 4. Thus, from the first outer connecting plate 11 towards the second inner connecting plate 33 ( Figure 2 (In the direction indicated by the arrow in the middle) there is an operating space for installing fasteners 4 on the second inner connecting plate 33. When the middle wall plate 200 is attached to the L-shaped structure of the middle structural part 3, the middle wall plate 200 can be easily fixed to the second inner connecting plate 33 using fasteners 4.

[0037] In one embodiment, the distance A between the outer surfaces of the first outer connecting plate 11 and the second outer connecting plate 21 on both sides of the partition wall keel 100 can be set to 100-120mm, the width B of the first outer connecting plate 11 and the second outer connecting plate 21 can be set to 30-60mm respectively, and the width A1 of the middle plate 31 can be set to 10-25mm.

[0038] The partition wall joists 100 in this embodiment are smaller than traditional joists, which can save on partition wall construction costs, but are not limited to the dimensions mentioned above. The distance A between the outer surfaces of the outer connecting plates 21 on both sides defines the spacing between the outer wall panels 300 on both sides. This spacing allows for a thinner partition wall. Because this application has good sound insulation and energy absorption performance, sound insulation requirements can be met even with a thinner partition wall. The width B is sufficient to allow for stable installation of the outer wall panels 300, and the width A1 of the middle plate 31 is approximately equivalent to the thickness of the middle wall panel 200.

[0039] Embodiments of this application also provide a partition wall, such as Figures 4-8 As shown, it includes an intermediate wall panel 200, an outer wall panel 300, and a partition wall keel 100 as described above. Intermediate wall panels 200 are installed on both sides of the intermediate plate 31 of the partition wall keel 100, and outer wall panels 300 are installed on the outer surfaces of the first outer connecting plate 11 and the second outer connecting plate 21, respectively.

[0040] In one embodiment, such as Figures 4-6 As shown, the intermediate wall panel 200 on one side of the intermediate plate 31 is inserted between the first inner connecting plate 32 and the second inner connecting plate 33, and the intermediate wall panel 200 on the other side is fixed to the second inner connecting plate 33 of the partition wall keel 100 by fasteners 4. The outer wall panel 300 can be fixed to the first outer connecting plate 11 and the second outer connecting plate 21 of the partition wall keel 100 by fasteners (such as screws).

[0041] In one embodiment, a filling cotton 400 is used to fill the space between the intermediate wall panel 200 and the outer wall panel 300, with a gap between the filling cotton 400 and the outer wall panel 300. The filling cotton 400 can be fixed to the first vibration damping plate 12 and the second vibration damping plate 22 of the partition wall keel 100 to stabilize its position. Optionally, the gap between the filling cotton 400 and the outer wall panel 300 can be 10-30mm. By using the filling cotton 400, sound energy can be further absorbed, improving sound insulation performance. Furthermore, by setting a gap between the filling cotton 400 and the outer wall panel 300, when sound is transmitted to the outer wall panel 300 and then to the filling cotton 400, some of the sound energy is absorbed by the filling cotton 400, and some of the sound energy oscillates back and forth in the space between the filling cotton 400 and the outer wall panel 300, thereby dissipating the sound energy and reducing the energy of sound transmitted to the other side of the partition wall.

[0042] In one embodiment, such as Figure 7 As shown, E-shaped keel 500s can be installed at both ends of the partition wall. The E-shaped keel 500 includes a base plate and three parallel abutment plates on the base plate. The outer wall panels 300 on both sides are respectively attached to the outer sides of the abutment plates of the E-shaped keel 500 on both sides. The middle wall panel 200 abuts against the middle abutment plate of the E-shaped keel 500. The base plate of the E-shaped keel 500 is fixed to the vertical wall.

[0043] Figure 4-6 The transverse cross-sectional structure of the partition wall is shown in some embodiments. Figures 4-6 In this embodiment, the partition wall keel 100 and the E-shaped keel 500 are placed vertically. The base plate of the E-shaped keel 500 is fixed to the vertical wall by fixing bolts 6, and fireproof sealant 5 can be installed between the base plate of the E-shaped keel 500 and the wall.

[0044] In some embodiments, such as Figure 8As shown, U-shaped keels 600 are respectively installed at the top and bottom ends of the partition wall. The U-shaped keel 600 includes a base plate and side plates located on both sides of the base plate. The partition wall keel 100 includes vertically installed vertical keels, with the top and bottom ends of the vertical keels located within the U-shaped keel 600. It may also include horizontal keels built horizontally on the vertical keels. The outer wall panels 300 on both sides abut against the outer side plates of the U-shaped keel 600. The base plate of the U-shaped keel 600 is fixed to the top or bottom plate of the building, and fireproof sealant 5 can be applied between the base plate of the U-shaped keel 600 and the top (or bottom) plate of the building. The base plate of the U-shaped keel 600 is fixed to the top or bottom plate of the building using fixing bolts 4. Specifically, during installation, the vertically arranged vertical keel can be pushed into the groove of the U-shaped keel 600 first, and the horizontal keel can be built. Then, the intermediate wall panel 200, the filling cotton 400 and the outer wall panel 300 can be installed.
