DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0043] The embodiment of the present application provides a partition wall keel 100, such as Figures 1-5 As shown (combined with Figures 6-12 ), the partition wall keel 100 includes: an intermediate structure part 1 and side structure parts 2 respectively located on both sides of the intermediate structure part 1; wherein,

[0044] The intermediate structure 1 includes an intermediate plate 11 and two inner connecting plates 12. The two inner connecting plates 12 are respectively connected to the two ends of the intermediate plate 11 and face opposite sides of the intermediate plate 11. Each inner connecting plate 12 is perpendicular to the intermediate plate 11 and forms an L-shaped structure with the intermediate plate 11. The L-shaped structure is configured to mount the intermediate wall panel 200. When the intermediate wall panel 200 is installed, one end abuts against the L-shaped structure and is fixed to the inner connecting plate 12 of the L-shaped structure.

[0045] The side structure portion 2 on each side includes an outer connecting plate 21 parallel to the inner connecting plate 12 and a connecting structure connecting the inner connecting plate 12 and the outer connecting plate 21 . The outer connecting plate 21 is configured to mount the exterior wall panel 300 on the outer surface.

[0046] The scheme provided by the embodiment of the present application can install the intermediate wall plate 200 on the middle structure part 1 of the partition wall keel 100, and install the outer wall plate 300 on the outer connecting plates 21 on both sides, so that the partition wall can play an effective sound insulation effect through the three-layer wall plate. Moreover, the inner connecting plates 12 of the middle structure part 1 of the partition wall keel 100 in the present application form an L-shaped structure with the middle plate body 11 respectively, when installing, one end of the intermediate wall plate 200 cooperates with the L-shaped structure (limited by the two adjacent side surfaces of the one end of the intermediate wall plate 200 by the L-shaped structure), and the intermediate wall plate 200 is fixed on the inner connecting plate 12, for example, the intermediate wall plate 200 can be fixed on the inner connecting plate 12 by the screw 3, and the installation of the intermediate wall plate 200 is firm. The way of installing the intermediate wall plate 200 not only makes the installation of the intermediate wall plate 200 firm, but also makes the construction mode of the partition wall more flexible and has high construction efficiency.

[0047] In some embodiments, the H-shaped structure is used to insert and install the intermediate wall plate, but since the intermediate wall plate is inserted into the slot of the H-shaped structure, the H-shaped structure needs to be built first, then the intermediate wall plate is inserted and installed, and the partition wall is built in turn. This construction mode cannot disassemble and assemble the intermediate wall plate at will, and since the intermediate wall plate has a gap on both sides of the slot of the H-shaped structure, the intermediate wall plate has the problem of unstable installation. The scheme of the present application uses the L-shaped structure to install the intermediate wall plate 200, the keel framework of the partition wall can be built first, then the intermediate wall plate 200 and the outer wall plate 300 are installed (since the intermediate partition wall 200 abuts against the L-shaped structure, there is no interference problem in installation), or the keel can be built first, the intermediate wall plate 200 is installed, and the partition wall is built in turn, and any intermediate wall plate 200 can be disassembled and assembled conveniently. Therefore, the partition wall keel 100 provided by the present application can make the construction of the partition wall more flexible, convenient to install, and improve the construction efficiency of the partition wall.

[0048] In addition, the thickness of the intermediate wall plate 200 used by the partition wall keel 100 in the present application can be greater than the width of the middle plate body 11, or less than the width of the middle plate body 11, so that the thickness range of the middle plate body 11 suitable for the partition wall keel 100 is large. Conversely, the thickness of the intermediate wall plate 200 inserted by the H-shaped structure needs to be adapted to the width of the slot of the H-shaped structure, too thick and it cannot be inserted, too thin and it will shake back and forth in the H-shaped slot.

[0049] In one embodiment, referring to Figure 3 and Figure 4 In the middle structure part 1, the middle plate body 11 and the inner connecting plate 12 are formed by bending, and the middle plate body 11 and the inner connecting plate 12 are bent to form the reinforcing rib 13, so that the rigidity of the middle structure part 1 can be enhanced by arranging the reinforcing rib 13.

[0050] In one embodiment, the connecting structure 22 connecting the inner connecting plate 12 and the outer connecting plate 21 is a deformable shock-absorbing plate. The deformable shock-absorbing plate 22 is arranged between the inner connecting plate 12 and the outer connecting plate 21. When sound is transmitted to the outer wall plate 300, the outer wall plate 300 vibrates, which drives the shock-absorbing plate 22 to vibrate and deform, so that the vibration and deformation of the shock-absorbing plate 22 can absorb sound energy and reduce the transmission of sound energy, thereby achieving sound insulation. In addition, the sound oscillates back and forth between the outer wall plate 300 and the intermediate wall plate 200, which also reduces the sound energy transmitted to the other side of the partition wall. In addition, the space between the outer wall plate 300 and the intermediate wall plate 200 can be filled with cotton 400, which can further reduce the transmission of sound. Therefore, the partition wall keel 100 provided by the application can reduce the thickness of the partition wall while meeting the sound insulation performance requirements, thereby reducing the cost of the partition wall.

[0051] In some example embodiments, as shown in Figures 1-4 , at least one side of the side structure part 2, the shock-absorbing plate 22 is connected to the end of the inner connecting plate 12 and the outer connecting plate 21 facing in opposite directions, and the inner connecting plate 12, the outer connecting plate 21 and the shock-absorbing plate 22 form a Z-shaped structure.

[0052] In the Z-shaped structure of the side structure part 2, the shock-absorbing plate 22 can include a first adapter plate 221 connected perpendicularly to the inner connecting plate 12, a second adapter plate 222 connected to the outer connecting plate 21, and an inclined plate 223 connecting the first adapter plate 221 and the second adapter plate 222. When sound vibration occurs, the sound is transmitted to the outer wall plate 300, so that the outer connecting plate 21 transmits the sound vibration to the shock-absorbing plate 22. During the vibration of the shock-absorbing plate 22, the inclined plate 223 will bend and deform relative to the first adapter plate 221 and the second adapter plate 222 to achieve shock absorption and energy absorption. Of course, the inclined plate 223 can also be directly connected to the inner connecting plate 12 and the outer connecting plate 21.

[0053] The side structure part 2 on both sides of the intermediate structure part 1 can adopt a Z-shaped structure, as shown in Figure 1 and Figure 3 , or only one side of the side structure part 2 can adopt a Z-shaped structure, and the other side of the side structure part 2 can adopt other structural forms, such as Figure 2 and Figure 4 .

[0054] In some example embodiments, at least one side of the side structure part 2, the shock-absorbing plate 22 is connected to the end of the inner connecting plate 12 and the outer connecting plate 21 facing in the same direction, and the shock-absorbing plate 22 is bent to form a deformable shock-absorbing recess, and the shock-absorbing recess is recessed towards the space between the inner connecting plate 12 and the outer connecting plate 21.

[0055] For reference Figure 2 and Figure 4In the example of FIG. 1 , the shock-absorbing plate 22 includes a first plate 224, a second plate 225, a third plate 226, a fourth plate 227, and an arc-shaped plate 228. The first plate 224 is vertically connected to the end of the inner connecting plate 12 away from the middle plate 11, the second plate 225 is vertically connected to the end of the outer connecting plate 21 closer to the first plate 224, the third plate 226 is vertically connected to the end of the first plate 224 away from the inner connecting plate 12, the fourth plate 227 is vertically connected to the end of the second plate 225 away from the outer connecting plate 21, and the arc-shaped plate 228 connects the third plate 226 and the fourth plate 227. The third plate 226, the fourth plate 227, and the arc-shaped plate 228 form the shock-absorbing recess. When the exterior wall panel 300 on one side generates sound vibration, the outer connecting plate 21 vibrates relative to the inner connecting plate 12, causing the third plate 226, the fourth plate 227, and the arc-shaped plate 228 to deform and absorb energy.

[0056] Figure 2 and Figure 4 In the example shown, the side structure 2 on one side of the partition wall stud 100 is configured to have the aforementioned shock-absorbing recess, while the side structure 2 on the other side is a Z-shaped structure. In other embodiments, the side structure 2 on both sides of the partition wall stud 100 may also have shock-absorbing recesses.

[0057] It is understandable that the structure of the shock absorbing plate 22 can also be various structural forms and is not limited to the above structure.

[0058] In other embodiments, such as Figure 5 and Figure 7 As shown, in the side structure portion 2 on each side, the inner connecting plate 12, the connecting structure 22 and the outer connecting plate 21 can be connected to each other to form a C-shaped structure.

[0059] exist Figures 1-5 In the embodiment, the end of the outer connecting plate 21 can also be bent to form a bent portion 23. Since the filling cotton 400 is provided between the outer connecting plate 21 and the inner connecting plate 12, the bent portion 23 can facilitate the installation of the filling cotton 400 and prevent it from falling out.

[0060] In one embodiment, Figure 6 and Figure 7 As shown, each inner connecting plate 12 is compared with the outer connecting plate 21 on the side away from the inner connecting plate 12. The end of the inner connecting plate 12 away from the middle plate 11 exceeds the outer connecting plate 21. The length d of the excess can be 10-15 mm. This size is sufficient as long as it is convenient for installing the screws 3. In this way, from the outer connecting plate 21 to the inner connecting plate 12 ( Figure 5In the direction indicated by the arrow in the figure, there is operating space for installing the screws 3 on the inner connecting plate 12. When the intermediate wall panel 200 is abutted against the L-shaped structure of the intermediate structural part 1, the intermediate wall panel 200 can be conveniently fixed to the inner connecting plate 12 using the screws 3.

[0061] In one embodiment, the distance A between the outer surfaces of the outer connecting plates 21 on both sides of the partition wall stud 100 can be set to 100-120 mm, the width B of the outer connecting plates 21 can be set to 30-60 mm, and the width A1 of the middle plate body 11 can be set to 12-18 mm.

[0062] The partition wall keel 100 in this embodiment is smaller than traditional keels, which can reduce partition wall construction costs. Of course, the dimensions are not limited to the above. The distance A between the outer surfaces of the external connecting plates 21 on both sides defines the spacing between the exterior wall panels 300 on both sides. This spacing allows for a thinner partition wall. Due to the excellent sound insulation and energy absorption performance of this application, sound insulation requirements can be met even with a thinner partition wall thickness. Width B is sufficient to allow for stable installation of the exterior wall panels 300. The width A1 of the intermediate plate body 11 is roughly equivalent to the thickness of the intermediate wall panel 200. Of course, the thickness of the intermediate wall panel 200 can be slightly greater than or slightly less than width A1.

[0063] The embodiment of the present application also provides a partition wall, such as Figures 8-12 As shown (combined with Figures 1-4 ), includes an intermediate wall panel 200, an outer wall panel 300 and the partition wall keel 100 as described above, the end of the intermediate wall panel 200 abuts against the L-shaped structure of the partition wall keel 100 and is fixed on the inner connecting plate 12, and the outer wall panel 300 is fixed on the outer surface of the outer connecting plate 21.

[0064] In one embodiment, Figures 10-12 As shown, the middle wall panel 200 is fixed to the inner connection plate 12 of the partition wall keel 100 by screws 3 , and the outer wall panel 300 is fixed to the outer connection plate 21 of the partition wall keel 100 by screws 3 .

[0065] In one embodiment, Figures 10-12As shown, the intermediate wall plate 200 and the outer wall plate 300 are filled with the filling cotton 400, and the filling cotton 400 has a space with the outer wall plate 300. The filling cotton 400 can be fixed on the shock-absorbing plate 22 of the partition wall stud 100 to stabilize the position of the filling cotton 400. Optionally, the space between the filling cotton 400 and the outer wall plate 300 can be 10-30mm. By setting the filling cotton 400, sound energy can be further absorbed to improve sound insulation performance. Moreover, by setting the space between the filling cotton 400 and the outer wall plate 300, when sound is transmitted to the outer wall plate 300 and then to the filling cotton 400, part of the sound energy is absorbed by the filling cotton 400, and part of the sound energy is oscillated back and forth in the space between the filling cotton 400 and the outer wall plate 300, so that the sound energy is consumed, and the energy of the sound transmitted to the other side of the partition wall is reduced.

[0066] In an embodiment, as shown in Figure 8 and Figure 9 shown, the left and right ends of the partition wall can be respectively provided with E-shaped studs 500, and the E-shaped stud 500 includes a bottom plate and three parallel abutting plates on the bottom plate. The outer wall plates 300 on both sides are respectively attached to the outer sides of the abutting plates on both sides of the E-shaped stud 500, and the intermediate wall plate 200 is abutted on the abutting plate in the middle of the E-shaped stud 500. The bottom plate of the E-shaped stud 500 is arranged to be fixed on the erected wall.

[0068] In an embodiment, as shown in Figure 12 ​​As shown, the upper and lower ends of the partition wall are respectively provided with U-shaped keels 600, the U-shaped keel 600 comprises a bottom plate and side plates on both sides of the bottom plate, the partition wall keel 100 comprises vertically arranged vertical keels, the upper and lower ends of the vertical keel are located in the U-shaped keel 600 respectively, and the vertical keel can further comprise a transverse keel transversely arranged on the vertical keel, and the outer wall plate 300 on both sides abuts against the outside of the side plate of the U-shaped keel 600. Wherein, the bottom plate of the U-shaped keel 600 is arranged to be fixed on the top plate or the bottom plate of the building, and the fireproof sealing adhesive 5 can be arranged between the bottom plate of the U-shaped keel 600 and the top plate (or the bottom plate) of the building, and the bottom plate of the U-shaped keel 600 is fixed on the top plate or the bottom plate of the building through the fixing bolt 4. Specifically, during installation, the vertically arranged vertical keel can be first pushed into the groove of the U-shaped keel 600, the transverse keel is built, and then the middle wall plate 200, the cotton 400 and the outer wall plate 300 are installed.
