Description

Technical Field

[0001] The utility model relates to the technical field of building sound insulation, in particular to a double-layer light steel keel sound insulation wall. Background Art

[0002] Light steel keel sound insulation wall is light in weight and has good sound insulation effect. It is widely used in offices, halls and hotel rooms in commercial buildings. Among them, this kind of light steel keel sound insulation wall is mostly used to separate separate offices in office spaces. After a single-layer light steel keel reaches a certain height, its structural stability cannot meet the requirements, which easily leads to deformation of the light steel keel and is difficult to adapt to high-rise buildings. Therefore, in order to improve the strength of the light steel keel sound insulation wall, a double-layer light steel keel sound insulation wall is now available.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the following defects exist: in order to improve the sound insulation effect, the light steel keel sound insulation walls currently used are mostly double-cavity. Most of the existing double-cavity sound insulation walls have keels fixed at both ends of the sound insulation board. During the installation process, the staff must first install the keel on one side and then fix the sound insulation board and the keel to each other. Then, the keel on the other side and the sound insulation board are fixed to each other. Then, the sound insulation cotton is stuffed into the keels on both sides. During this process, the staff's work is difficult. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a double-layer light steel keel sound insulation wall.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a double-layer light steel keel sound insulation wall, including a horizontal keel frame, the upper surface of which is symmetrically installed with two mutually symmetrical vertical keels, the vertical keel frame including two first keels symmetrically installed on the upper surface of the horizontal keel frame, two second keel frames symmetrically installed on the upper surface of the horizontal keel frame, and two connecting members respectively fixed on the side walls of the two first keels close to the second keel frames, the two connecting members are respectively fixed to the adjacent second keel frames, and installation grooves are opened on the two opposite side walls of the connecting member, and sound insulation panels are installed in the two adjacent installation grooves.

[0006] By adopting the above technical solution, when the staff needs to install the soundproof wall, the staff needs to first install the vertical keel frame on the horizontal keel frame. At this time, the staff installs the sound insulation board into the installation groove. Afterwards, the staff can stuff the sound insulation cotton into the first keel frame and the second keel frame. In this process, the difficulty of installing the soundproof wall is reduced, thereby reducing the difficulty of the staff's work.

[0007] Furthermore, mounting plates are fixedly provided on the side walls of the two first keel frames that are close to each other, and a connecting device is commonly installed on the side walls of the two mounting plates that are close to each other.

[0008] By adopting the above technical solution, when the staff needs to install the sound insulation board, the staff needs to align the two ends of the sound insulation board with the installation grooves. Then, the staff needs to start the connection device, so that the two vertical keels move towards each other under the action of the connection device, so that the two opposite side walls of the sound insulation board are respectively abutted against the inner walls of the two adjacent installation grooves, and then the installation of the sound insulation board is completed. In this process, the difficulty of installing the sound insulation board is reduced, thereby reducing the difficulty of the staff's work.

[0009] Furthermore, the connecting device includes two connecting rods respectively fixedly arranged on the side walls of the two mounting plates close to each other and connecting sleeves with two ends respectively sleeved on the outer walls of the two connecting rods.

[0010] Furthermore, an external thread is provided on the outer wall of the connecting rod, and an internal thread is provided on the inner wall of the connecting sleeve, and the external thread and the internal thread match each other.

[0011] By adopting the above technical solution, when the staff needs to move the two vertical keel frames toward each other under the action of the connecting device, the staff needs to rotate the connecting sleeve to make the external thread and the internal thread engage with each other, so that the two connections move toward each other under the action of the threaded sleeve, and then the two vertical keel frames move toward each other under the action of the connecting device, so that the two opposite side walls of the sound insulation board are respectively abutted against the inner walls of the two adjacent installation grooves, thereby completing the installation of the sound insulation board. In this process, the difficulty of installing the sound insulation board for the staff is reduced, thereby reducing the difficulty of the staff's work.

[0012] Furthermore, mounting holes are formed through the two opposite side walls of the horizontal keel frame, and fixing holes are formed through the side walls of the first keel frame and the second keel frame that are away from each other, bolts are installed in the mounting holes, nuts are threadedly connected to the side walls of the bolts, and the bolts pass through the fixing holes and are threadedly connected to the nuts.

[0013] By adopting the above technical solution, when the staff needs to install the vertical keel frame, the staff needs to make the installation hole and the fixing hole face each other. Then, the staff installs the bolts into the installation hole and the fixing hole. At this time, the staff installs the nut on the outer wall of the bolt, and then makes the side wall of the nut abut against the side wall of the vertical keel frame, thereby completing the installation of the vertical keel frame.

[0014] Furthermore, the cross section of the fixing hole is a rectangle with rounded corners at both ends.

[0015] By adopting the above technical solution, the cross section of the fixing hole is a rectangle with rounded corners at both ends, which reduces the probability of the fixing hole causing obstruction when the staff moves the vertical keel frame, thereby improving the stability of the device.

[0016] Furthermore, a sliding groove is provided on a side wall of one of the connecting rods close to the other connecting rod, a sliding rod is slidably arranged in the sliding groove, and the sliding rod and the other connecting rod are fixed to each other.

[0017] By adopting the above technical solution, when the vertical keel frame moves, the slide rod and the slide groove slide relative to each other. During this process, the slide rod and the slide groove reduce the probability of shaking when the vertical keel frame moves, thereby improving the stability of the device.

[0018] Furthermore, a limiting groove is provided on the inner wall of the slide rod, a limiting block is slidably arranged in the limiting groove, and the limiting block and the slide rod are fixed to each other.

[0019] By adopting the above technical solution, when the slide bar slides, the limit block slides synchronously with the slide bar. During this process, the limit block reduces the probability of the slide bar and the slide groove being separated from each other, thereby improving the stability of the device.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to install the soundproof wall, the staff must first install the vertical keel frame on the horizontal keel frame. At this time, the staff installs the soundproof board into the installation groove. Afterwards, the staff can stuff the soundproof cotton into the first keel frame and the second keel frame. In this process, the difficulty of installing the soundproof wall is reduced, thereby reducing the difficulty of the staff's work;

[0022] 2. In this application, when the staff needs to install the sound insulation board, the staff needs to align the two ends of the sound insulation board with the installation groove. Then, the staff needs to start the connection device, so that the two vertical keels move towards each other under the action of the connection device, so that the two opposite side walls of the sound insulation board are respectively abutted against the inner walls of the two adjacent installation grooves, thereby completing the installation of the sound insulation board. In this process, the difficulty of installing the sound insulation board is reduced, thereby reducing the difficulty of the staff's work;

[0023] 3. In the present application, when the staff needs to move the two vertical keels toward each other under the action of the connecting device, the staff needs to rotate the connecting sleeve to make the external thread and the internal thread engage with each other, so that the two connections move toward each other under the action of the threaded sleeve, and then the two vertical keels move toward each other under the action of the connecting device, so that the two opposite side walls of the sound insulation board are respectively abutted against the inner walls of the two adjacent installation grooves, thereby completing the installation of the sound insulation board.

[0030] like Figure 1-4As shown, the embodiment of the present application discloses a double-layer light steel keel soundproof wall, comprising a horizontal keel frame 1, a vertical keel frame 11, a sound insulation board 12, a mounting plate 3, a connecting device 31, a bolt 5, a nut 51 and a sliding rod 6. The vertical keel frame 11 is provided with two and symmetrically installed on the upper surface of the horizontal keel frame 1, and the vertical keel frame 11 comprises a first keel frame 111, a second keel frame 112 and a connecting member 113.

The sound insulation board 12 is a rectangular plate-shaped structure, and the sound insulation board 12 is installed in two adjacent mounting grooves 2.

[0031] When the staff needs to install the soundproof wall, the staff needs to first install the vertical keel frame 11 on the horizontal keel frame 1. At this time, the staff installs the soundproof board 12 into the installation groove 2. Afterwards, the staff can stuff the soundproof cotton into the first keel frame 111 and the second keel frame 112. In this process, the difficulty of installing the soundproof wall is reduced, thereby reducing the difficulty of the staff's work.

[0032] The mounting plate 3 is a rectangular plate-shaped structure. Two mounting plates 3 are provided and are respectively fixedly arranged on the side walls of the two first keel frames 111 close to each other. The two ends of the connecting device 31 are respectively installed on the side walls of the two mounting plates 3 close to each other.

[0033] When the staff needs to install the sound insulation board 12, the staff needs to align the two ends of the sound insulation board 12 with the installation grooves 2. Then, the staff needs to start the connection device 31, so that the two vertical keels 11 move toward each other under the action of the connection device 31, so that the two opposite side walls of the sound insulation board 12 are respectively abutted against the inner walls of the two adjacent installation grooves 2, and then the installation of the sound insulation board 12 is completed. In this process, the difficulty of installing the sound insulation board 12 is reduced, thereby reducing the difficulty of the staff's work.

[0034] The connecting device 31 includes a connecting rod 311 and a connecting sleeve 312. The connecting rod 311 is a round rod-shaped structure with a horizontal axis. Two connecting rods 311 are provided and are respectively fixed on the side walls of the two mounting plates 3 that are close to each other. The connecting sleeve 312 is an internally hollow cylindrical structure with an axis that coincides with the axis of the connecting rod 311.

[0040] A sliding groove 23 is provided on the side wall of one connecting rod 311 close to the other connecting rod 311 . The sliding rod 6 is a round rod structure, and its axis coincides with the axis of the connecting rod 311 . The sliding rod 6 is slidably arranged in the sliding groove 23 , and the sliding rod 6 and the other connecting rod 311 are fixed to each other.

[0041] When the vertical keel frame 11 moves, the slide bar 6 and the slide groove 23 slide relative to each other. During this process, the slide bar 6 and the slide groove 23 reduce the probability of shaking when the vertical keel frame 11 moves, thereby improving the stability of the device.

[0042] In order to improve the stability of the device, a limiting groove 24 is provided on the inner wall of the slide bar 6, and a limiting block 7 is slidably arranged in the limiting groove 24, and the limiting block 7 is fixed to the slide bar 6. When the slide bar 6 slides, the limiting block 7 follows the sliding and slides synchronously, and in this process, the limiting block 7 reduces the probability of the slide bar 6 and the slide groove 23 being separated from each other, thereby improving the stability of the device.
