[0027] The embodiment of the present application provides a partition wall keel 100, such as Figure 1-Figure 5 As shown (combined with Figure 6-Figure 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, The intermediate structure 1 includes an intermediate plate body 11 and two inner connecting plates 12. The two inner connecting plates 12 are respectively connected to the two ends of the intermediate plate body 11 and face the opposite sides of the intermediate plate body 11. Each inner connecting plate 12 is perpendicular to the intermediate plate body 11 and forms an L-shaped structure with the intermediate plate body 11. The L-shaped structure is configured to install the intermediate wall panel 200. When the intermediate wall panel 200 is installed, one end of the intermediate wall panel 200 abuts against the L-shaped structure and is fixed to the inner connecting plate 12 of the L-shaped structure. The side structure part 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.

[0028] In the solution provided by the embodiment of the present application, the middle wall panel 200 can be installed on the middle structure part 1 of the partition wall keel 100, and the outer wall panels 300 can be installed on the outer connection panels 21 on both sides. The three-layer wall panels can make the partition wall play an effective sound insulation role. Moreover, the inner connection panels 12 of the middle structure part 1 of the partition wall keel 100 in the present application respectively form an L-shaped structure with the middle plate body 11. During installation, one end of the middle wall panel 200 cooperates with the L-shaped structure (the two adjacent side surfaces of one end of the middle wall panel 200 are limited by the L-shaped structure), and the middle wall panel 200 is fixed on the inner connection panel 12. For example, the middle wall panel 200 can be fixed on the inner connection panel 12 by screws 3, and the middle wall panel 200 is firmly installed. This method of installing the middle wall panel 200 not only makes the middle wall panel 200 firmly installed, but also makes the construction method of the partition wall more flexible and efficient.

[0029] In some embodiments, an H-shaped structure is used to insert the middle wall panel, but because the middle wall panel is inserted into the slot of the H-shaped structure, the partition wall constructed by the H-shaped structure needs to build a keel, and then insert a middle wall panel, and then build it in sequence. In this construction method, one of the middle wall panels cannot be disassembled and assembled at will, and because there is a gap between the middle wall panel and the two sides of the slot of the H-shaped structure, the middle wall panel has the problem of unstable installation. The solution of the present application uses an L-shaped structure to install the middle wall panel 200. The keel skeleton of the partition wall can be built first, and then the middle wall panel 200 (because the middle partition wall 200 is against the L-shaped structure, there is no interference problem of the slot during installation) and the outer wall panel 300 can be installed. It is also possible to first build a keel and install a middle wall panel 200, that is, to build in sequence, and any of the middle wall panels 200 can be easily disassembled and assembled. 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.

[0030] In addition, the thickness of the intermediate wallboard 200 used in the partition wall keel 100 of the present application can be greater than the width of the intermediate plate body 11, or less than the width of the intermediate plate body 11, so the thickness range of the intermediate plate body 11 applicable to the partition wall keel 100 is relatively large. On the contrary, in the method of plugging the intermediate wallboard 200 in the H-shaped structure, the thickness of the intermediate wallboard 200 needs to be adapted to the width of the H-shaped structure slot. If it is too thick, it cannot be inserted, and if it is too thin, it will shake back and forth in the H-shaped slot.

[0031] In one embodiment, reference Figure 3 and Figure 4 In the intermediate structure 1, the intermediate plate 11 and the inner connecting plate 12 are formed by bending, and a reinforcing rib 13 is formed by bending between the intermediate plate 11 and the inner connecting plate 12. By providing the reinforcing rib 13, the rigidity of the intermediate structure 1 can be enhanced.

[0032] In one embodiment, the connection structure 22 connecting the inner connection plate 12 and the outer connection plate 21 is a deformable shock-absorbing plate. A deformable shock-absorbing plate 22 is arranged between the inner connection plate 12 and the outer connection plate 21. When the sound is transmitted to the outer wall plate 300, the outer wall plate 300 vibrates, which will drive the shock-absorbing plate 22 to vibrate and deform, so that the vibration deformation of the shock-absorbing plate 22 will absorb the sound energy and reduce the propagation of the sound energy, thereby playing a sound insulation role. Moreover, the sound oscillates back and forth between the outer wall plate 300 and the middle wall plate 200, which will also reduce the sound energy transmitted to the other side of the partition wall. In addition, the space between the outer wall plate 300 and the middle wall plate 200 can also be provided with filling cotton 400, and the filling cotton 400 can further reduce the sound transmission. Therefore, the partition wall keel 100 provided in the present application can reduce the thickness of the partition wall while meeting the requirements of the sound insulation performance, thereby reducing the cost of the partition wall.

[0033] In some exemplary embodiments, Figure 1-Figure 4 As shown, in at least one side of the side structure part 2, the damping plate 22 is respectively connected to the ends 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 damping plate 22 form a Z-shaped structure.

[0034] In the side structure part 2 of the Z-shaped structure, the damping plate 22 may include a first adapter plate 221 vertically connected 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 is generated, the sound is transmitted to the outer wall plate 300, so that the outer connecting plate 21 transmits the sound vibration to the damping plate 22. During the vibration of the damping 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. Of course, the inclined plate 223 can also be directly connected to the inner connecting plate 12 and the outer connecting plate 21.

[0035] The side structural parts 2 on both sides of the middle structural part 1 can respectively adopt a Z-shaped structure, such as Figure 1 and Figure 3 In the example of FIG. 1 , only one side structure portion 2 may be a Z-shaped structure, while the other side structure portion 2 may adopt other structural forms, such as Figure 2 and Figure 4 .

[0036] In some exemplary embodiments, in the side structure portion 2 on at least one side, the shock-absorbing plate 22 is respectively connected to the ends of the inner connecting plate 12 and the outer connecting plate 21 facing the same direction, and the shock-absorbing plate 22 is bent to form a deformable shock-absorbing recess, which is recessed toward the space between the inner connecting plate 12 and the outer connecting plate 21.

[0037] refer to Figure 2 and Figure 4 In the example of the embodiment, the damping plate 22 includes a first plate body 224, a second plate body 225, a third plate body 226, a fourth plate body 227 and an arc plate 228; the first plate body 224 is vertically connected to the end of the inner connecting plate 12 away from the middle plate body 11, the second plate body 225 is vertically connected to the end of the outer connecting plate 21 close to the first plate body 224, the third plate body 226 is vertically connected to the end of the first plate body 224 away from the inner connecting plate 12, the fourth plate body 227 is vertically connected to the end of the second plate body 225 away from the outer connecting plate 21, and the arc plate 228 connects the third plate body 226 and the fourth plate body 227, and the third plate body 226, the fourth plate body 227 and the arc plate 228 form the damping recess. When the outer wall panel 300 on one side generates sound vibration, the outer connecting plate 21 vibrates relative to the inner connecting plate 12, and the third plate body 226, the fourth plate body 227 and the arc plate 228 are deformed to absorb energy.

[0038] Figure 2 and Figure 4 In the example shown in FIG. 1 , the side structure part 2 on one side of the partition wall keel 100 is configured to have the shock absorbing recess as described above, and the side structure part 2 on the other side is a Z-shaped structure. In other embodiments, the side structure parts 2 on both sides of the partition wall keel 100 may also have shock absorbing recesses.

[0039] 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-mentioned structure.

[0040] In some other embodiments, Figure 5 and Figure 7 As shown, in the side structure part 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.

[0041] exist Figure 1-Figure 5In the embodiment, the end of the outer connecting plate 21 can also be bent to form a bent portion 23. Since the stuffing 400 is arranged between the outer connecting plate 21 and the inner connecting plate 12, the bent portion 23 can help install the stuffing 400 and prevent it from falling out.

[0042] In one embodiment, Figure 6 and Figure 7 As shown, 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, and the length d of the excess can be 10-15mm, which is sufficient as long as the screw 3 can be easily installed. In this way, the direction from the outer connecting plate 21 to the inner connecting plate 12 ( Figure 5 There is operating space for installing screws 3 on the inner connecting plate 12 (in the direction indicated by the arrow in the figure). When the middle wall panel 200 is abutted against the L-shaped structure of the middle structural part 1, the middle wall panel 200 can be conveniently fixed to the inner connecting plate 12 using screws 3.

[0043] In one embodiment, the distance A between the outer surfaces of the outer connecting plates 21 on both sides of the partition wall keel 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.

[0044] The partition wall keel 100 in this embodiment is smaller in size than the traditional keel, which can save the construction cost of the partition wall, and is of course not limited to the above size. Among them, the size of the distance A between the outer surfaces of the external connection plates 21 on both sides defines the spacing between the exterior wall panels 300 on both sides. The size setting of this spacing can make the thickness of the partition wall thinner. Because the sound insulation and energy absorption performance of this application is better, the sound insulation requirements can also be met when a thinner partition wall thickness is used. The width B is sufficient to stably install the exterior wall panel 300. The width A1 of the middle plate body 11 is roughly equivalent to the thickness of the middle wall panel 200. Of course, the thickness of the middle wall panel 200 can be slightly larger than the width A1 or slightly smaller than the width A1.

[0045] The embodiment of the present application also provides a partition wall, such as Figure 8-Figure 12 As shown (combined with Figure 1-Figure 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.

[0046] In one embodiment, Figure 10-12As shown, the middle wall panel 200 is fixed to the inner connection plate 12 of the partition wall keel 100 by means of screws 3 , and the outer wall panel 300 is fixed to the outer connection plate 21 of the partition wall keel 100 by means of screws 3 .

[0047] In one embodiment, Figure 10-12 As shown, the middle wall panel 200 and the outer wall panel 300 are filled with stuffing cotton 400, and there is a gap between the stuffing cotton 400 and the outer wall panel 300, wherein the stuffing cotton 400 can be fixed on the shock-absorbing plate 22 of the partition wall keel 100 to stabilize the position of the stuffing cotton 400. Optionally, the gap between the stuffing cotton 400 and the outer wall panel 300 can be 10-30 mm. By setting the stuffing cotton 400, sound energy can be further absorbed and the sound insulation performance can be improved. Moreover, by setting a gap between the stuffing cotton 400 and the outer wall panel 300, when the sound is transmitted to the outer wall panel 300 and then to the stuffing cotton 400, part of the sound energy is absorbed by the stuffing cotton 400, and part of the sound energy oscillates back and forth in the space between the stuffing cotton 400 and the outer wall panel 300, so that the sound energy is consumed, reducing the energy of the sound transmitted to the other side of the partition wall.

[0048] In one embodiment, Figure 8 and Fig. 9 As shown, E-shaped keels 500 can be respectively arranged at the left and right ends of the partition wall, and the E-shaped keel 500 includes a bottom plate and three parallel abutment plates on the bottom plate, and the exterior wall panels 300 on both sides are respectively attached to the outer sides of the abutment plates on both sides of the E-shaped keel 500, and the middle wall panel 200 abuts against the abutment plate in the middle of the E-shaped keel 500; wherein, the bottom plate of the E-shaped keel 500 is arranged to be fixed on the vertical wall.

Figure 1 The partition wall keel 100 shown, Fig.11 The cross-sectional structure of another embodiment of the partition wall is shown. Figure 2 The partition wall keel 100 shown in FIG. Fig.10 and Fig.11 In the embodiment, the partition keel 100 and the E-shaped keel 500 are placed vertically, the bottom plate of the E-shaped keel 500 is fixed to the vertical wall by fixing bolts 4, and a fireproof sealant 5 can be provided between the bottom plate of the E-shaped keel 500 and the wall.

[0050] In one embodiment, if Fig.12As shown, the upper and lower ends of the partition wall are respectively provided with U-shaped keels 600, and the U-shaped keel 600 includes a bottom plate and side plates located on both sides of the bottom plate. The partition wall keel 100 includes a vertical keel installed vertically, and the upper and lower ends of the vertical keel are respectively located in the U-shaped keel 600, and may also include a transverse keel built transversely on the vertical keel, and the exterior wall panels 300 on both sides abut against the outer side of the side plates of the U-shaped keel 600. Among them, the bottom plate of the U-shaped keel 600 is set to be fixed on the top plate or bottom plate of the building, and a fireproof sealant 5 can be set between the bottom plate of the U-shaped keel 600 and the top plate (or bottom plate of the building), and the bottom plate of the U-shaped keel 600 is fixed to the top plate or bottom plate of the building through fixing bolts 4. Specifically, during installation, the vertical keels arranged vertically may be first pushed into the grooves of the U-shaped keels 600 , and the transverse keels may be constructed, and then the middle wall panels 200 , the filling cotton 400 and the exterior wall panels 300 may be installed.

[0051] The partition wall provided in the embodiment of the present application has excellent sound insulation performance, small thickness, light weight and low cost. The partition wall provided in one embodiment has a sound insulation improvement of about 4dB compared with the partition wall constructed with double rows of 50 keels in the prior art, and compared with the thickness of 208mm of the double row C75 keel partition wall, the minimum thickness of the partition wall using the keel of the patent can be 136mm. The wall thickness is reduced by about 30%.
