AI Technical Summary
Traditional light steel keel/paper film gypsum board walls have shortcomings in sound insulation, especially because the gypsum board on both sides of the keel forms acoustic bridge, resulting in poor sound insulation effect. Methods to improve sound insulation effect usually increase the wall thickness and construction complexity.
The broken-bridge wall keel is used to destroy or weaken the acoustic bridge effect of the keel through the resonance points of different materials. The broken bridge keel includes a profile substrate and a metal side plate. The hook of the metal side plate is locked to the arc-shaped head of the profile substrate, and is matched with a non-metallic clip to enhance the sound insulation effect by using the structure of the clip.
While maintaining the thickness of the wall, the sound insulation effect of the wall is significantly improved, achieving a sound insulation effect of 50 decibels or higher, simplifying the construction process.

Description
Technical Field
[0001] The utility model relates to a broken bridge type wall keel. Background Art
[0002] Traditional light steel keel / paper film gypsum board walls are widely used due to their convenient assembly, dry construction, and ability to accommodate pipelines in the wall. However, for wall sound insulation, the keel forms a sound bridge between the gypsum boards on both sides, which deteriorates the sound insulation effect. For walls with high sound insulation requirements, the standard practice is to use double-row keels with staggered installation or intermediate plywood. Although this method can improve the sound insulation effect, it is complicated to construct and increases the wall thickness. Utility Model Content
[0003] The utility model aims to provide a broken bridge type wall keel, which can reduce the thickness of the wall and improve the sound insulation effect of the wall.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A broken bridge type wall keel comprises a profile base plate and two metal side plates. The two metal side plates are respectively locked at two sides of the profile base plate, and the profile base plate at the locking position is made of non-metallic material.
[0006] The metal side plate comprises a bottom plate, one end of which is L-shaped, and the other end of which is hook-shaped.
[0007] The profile base plate is made of non-metal material and is U-shaped. The free ends of the two side plates are arc-shaped heads. The hooks of the metal side plates are locked with the arc-shaped heads of the profile base plate.
[0008] The profile base plate is made of metal and its two sides are covered with soft films. The profile base plate is U-shaped, and the free ends of its two side plates are in an inner curling shape, and the hooks of the metal side plates are locked with the soft films.
[0009] The bottom plate of the profile base plate is provided with through holes for core keel assembly or transverse wiring.
[0010] The outer side of the metal side plate is covered with a soft film.
[0011] The broken bridge keel is equipped with a clip, which is made of non-metallic material and is integrally formed, including an inverted concave plate and two ear plates arranged on both sides of the inverted concave plate. The groove cover of the inverted concave plate is pressed on the through-core keel, and the two ear plates are provided with slots. The inner folding edge of the broken bridge keel is inserted into the slot.
[0012] The thermal break keel is matched with a clip, which spans the through-core keel. The clip is made of non-metallic material and is integrally formed, including a vertical plate. Notches are provided on the bottom wall and two side walls of the vertical plate. The lower notch spans the through-core keel, and a convex plate is provided on one side of the vertical plate at the notches on both sides. The end of the convex plate and the end of the vertical plate form a gap, and the inner folded edge of the thermal break keel is inserted in the gap.
[0013] The clip is made of plastic.
[0014] Beneficial effects of the utility model: The utility model aims to utilize the difference in resonance points of different materials to destroy or weaken the sound bridge effect of the keel, so that the light steel keel / paper film gypsum board wall can improve the sound insulation effect of the wall under the premise of conventional single-row keel assembly. At the same time, the necessary thickness of the wall is reduced and the installation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is necessary to make it clear in advance.
[0029] like Figures 1 to 3 , Figure 7 As shown, a preferred embodiment of the utility model is a thermally-broken wall keel, comprising a profile base plate 1 and two metal side panels 2. The profile base plate 1 is made of non-metallic material and is U-shaped, and the free ends of its two side panels are arc-shaped heads. The metal side panel 2 includes a bottom plate, one end of which is L-shaped to form an inner folding edge, and the other side of the bottom plate is hook-shaped. The hooks of the two metal side panels are correspondingly linearly riveted (locked) to the arc-shaped head of the profile base plate. A soft film may be covered on the outside of the metal side panel to further improve the sound insulation performance. An L-shaped top and bottom keel 3 is arranged on at least one outer side of the keel frame of the thermally-broken wall keel arrangement. A hole 11 is opened on the profile base plate 1 for assembling the core keel 4 or for horizontal wiring.
[0030] The profile base plate has a thickness of 3 mm, a length of 68.5 mm, a radius of the arc head of 2.6 mm, and a distance from the center of the arc head to the outer wall of the bottom plate of 10 mm. The metal side plate has a thickness of 0.7 mm, a length of 50 mm, a width of the L-shaped end of 10 mm, a radius of the curved arc of the hook portion of 3.4 mm, an open edge of the hook portion of 7 mm, and an angle of 15 degrees between the open edge and the bottom plate of the metal side plate (parameters before locking). The above parameters are given for reference only and are not intended to limit the structural data.
[0031] like Figures 4 to 7 As shown, another preferred embodiment of the utility model is a broken bridge type wall keel, comprising a profile base plate 10 and two metal side plates 20. The profile base plate is made of metal and is covered with soft film on both sides. The profile base plate is U-shaped, and the free ends of the two side plates are in the shape of inner curling edges; the metal side plate includes a bottom plate, one end of which is L-shaped to form an inner folding edge, and the other side of the bottom plate is hook-shaped; the hook of the metal side plate is locked with the soft film 30. The bottom plate of the profile base plate is provided with a through hole for core keel assembly or horizontal wiring. The outer surface of the metal side plate is coated with a soft film. Its fire protection grade can be made into Class A.
[0032] In order to further improve the sound insulation effect of the thermal insulation wall, the thermal insulation keel can be equipped with non-metallic clips, which use the resonance points of different materials to destroy or weaken the sound bridge effect of the keel. Install non-metallic keel clips between the two inner folds of the thermal insulation keel, such as Fig. 8A and Figure 8B The clip has two structures, namely, clip one 5A and clip two 5B. The clip one is integrally formed, including an inverted concave plate and two ear plates arranged on both sides of the inverted concave plate. The groove cover of the inverted concave plate is pressed on the through-core keel. The two ear plates are provided with slots, and the inner folding edge of the broken bridge keel is inserted into the slots. The bottom of the slot of the clip one is supported on the keel, which can obtain a better support accuracy; but at the same time, it also requires the accuracy of the keel itself to be sufficient. The clip two includes a vertical plate, and notches are provided on the bottom wall and both side walls of the vertical plate. The lower notch straddles the through-core keel, and a protrusion is provided on one side of the vertical plate at the notch on both sides. The end of the clamping plate and the end of the vertical plate form a gap, and the inner folding edge of the broken bridge keel is inserted in the gap. The keel is clamped by the protrusion on the vertical plate, and it can be used even if the error of the keel bending is large.
[0033] Hotels above four stars require partition walls with a sound insulation of 50 decibels. Generally, two conventional 50mm keels are used, and then five layers of boards are added. The thickness of each layer of boards is 12mm, and the wall thickness is 160mm. At present, everyone is willing to make the walls thinner. 120mm thick partition walls are very common, but the sound insulation effect can only reach 45 decibels.
[0034] If the 70mm thermal insulation wall keel of the utility model is used, plus 4 layers of boards, each layer of boards is 12mm, and the wall thickness is 120mm, the sound insulation effect of 50 decibels can also be achieved.
[0035] If you want to achieve 55 decibels of sound insulation, you need a 120mm thick wall, and then make two layers of overhead, the wall thickness is at least 200mm. If the wall thickness is still 120mm based on the broken bridge wall keel of the utility model, it is necessary to add a soft film between the boards, and the sound insulation effect of 55 decibels can also be achieved.
[0036] The traditional high sound insulation wall blocks the sound bridge by means of structural separation. Therefore, while improving the sound insulation effect, it will increase the space occupied, thereby increasing the wall thickness. However, the broken bridge keel described in the utility model has separated the sound bridge itself, so the sound insulation effect is independent of the wall thickness.
