Description

Technical Field

[0001] The utility model relates to the technical field of membrane curtain walls, in particular to a sound-insulating and noise-reducing grid cloth curtain wall membrane structure. Background Technique

[0002] The membrane curtain wall system is a new generation of building curtain wall product with membrane structure materials as the panel and aluminum alloy profiles as the supporting skeleton. The membrane curtain wall system can be divided into three categories according to the structural appearance: hidden frame membrane curtain wall, exposed frame membrane curtain wall and exposed-hidden combined membrane curtain wall; it can be divided into three categories according to the characteristics of the membrane material structure: single-layer membrane curtain wall, inflatable membrane curtain wall and composite membrane curtain wall. The membrane curtain wall system can be used as the external enclosure structure of various buildings. With its superior lighting performance, building appearance and safety performance, it is more suitable for buildings such as schools, hospitals and nursing homes where glass curtain walls are prohibited.

[0003] In the patent document with the publication number of CN 212427528 U, a membrane structure curtain wall is disclosed. By setting the first clamping plate, the second clamping plate and the buffer mechanism, the traditional point connection when connecting the membrane sheets is transformed into surface connection, increasing the connection area and improving the connection stability. Under the action of wind force, the membrane sheet undergoes a small deformation. The membrane sheet drives the tension spring to stretch through the first clamping plate and the telescopic block, playing a buffering role and providing space for the small deformation of the membrane sheet. By fixedly connecting a first compression spring between the first limiting block and the second limiting block, under the action of wind force, the membrane sheet undergoes a small deformation. The membrane sheet drives the tension spring to stretch through the first clamping plate and the telescopic block, and the first limiting block and the second limiting block approach each other, causing the first compression spring to be compressed, which can further enhance the buffering effect. In the process of realizing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, the membrane sheet is fixed by the first clamping plate and the second clamping plate. Although the contact range is increased, the first clamping plate and the second clamping plate are only fixed by two bolts, and the fixing property of the middle position between the first clamping plate and the second clamping plate is weak. Under the continuous interference of external wind force, the middle position of the membrane sheet between the first clamping plate and the second clamping plate will be displaced under the influence of tension. At the same time, the fixing piece and the telescopic block are only connected by a tension spring, and the fixing effect is poor. The tension spring is prone to rust and damage in the external environment. Once the tension spring is damaged, it will cause the membrane sheet to be misaligned or even fall off, making it inconvenient to use.

[0005] Therefore, it is necessary to provide a sound-insulating and noise-reducing grid cloth curtain wall membrane structure to solve the above technical problems. Content of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide a sound-insulating and noise-reducing grid cloth curtain wall membrane structure to solve the problems put forward in the above background technique.

[0007] The sound-insulating and noise-reducing grid cloth curtain wall membrane structure provided by the utility model includes a mounting seat, a mounting groove arranged in the mounting seat, and a grid membrane material arranged in the mounting groove. A fixing component for fixing the grid membrane material is arranged inside the mounting seat. One side of the mounting seat is fixedly connected with a fixing seat. A rotating rod is rotatably connected to the inner wall of the fixing seat. A connecting rod is fixedly connected to the outer side of the rotating rod. A connecting component is arranged at one end of the connecting rod, and a mounting plate is arranged on one side of the connecting component.

[0008] In order to achieve the effect of fixing the grid membrane material, preferably, the fixing component includes fixing screws arranged on one side of the mounting seat. The number of the fixing screws is two. A pressing plate is sleeved on the fixing screws. The pressing plate is located in the mounting groove, and nuts are screwed on the fixing screws.

[0009] In order to achieve the effect of improving the stability of the grid membrane material, preferably, the fixing component further includes a through groove opened inside the pressing plate. A resisting plate is inserted into the through groove. A resisting block is fixedly connected to one side of the resisting plate. A resisting groove matched with the resisting block is opened on one side of the mounting seat. A fixing block is integrally arranged on one side of the pressing plate. A tightening screw is screwed in the fixing block, and one end of the tightening screw abuts against one side of the resisting plate.

[0010] In order to achieve the effect of buffering the grid membrane material, preferably, the connecting component includes a connecting seat arranged on the outer side of the connecting rod. A placing groove matched with the connecting rod is opened inside the connecting seat. A fixing plate is fixedly connected to one end of the connecting rod. A spring is sleeved on the connecting rod. A sealing cover is bolted and fixed on one side of the connecting seat. A sealing block is integrally arranged on one side of the sealing cover.

[0011] In order to achieve the effect of facilitating the installation and disassembly of the spring, preferably, two ends of the spring are respectively attached to the inner wall of the connecting seat and one side of the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] For this sound-insulating and noise-reducing grid cloth curtain wall membrane structure, the grid membrane material is integrally pressed by the pressing plate, improving the stability of the grid membrane material. The grid membrane material is further pressed and fixed on one side by the resisting plate and the resisting block on one side thereof. After the resisting block enters the resisting groove, a better fixing effect on the grid membrane material is achieved. Even in the case of strong wind, the grid membrane material is not likely to displace. When the grid membrane material is affected by wind force, the connecting rod and the fixing plate move in the placing groove and squeeze the spring. At the same time, the connecting rod is rotationally matched with the fixing seat through the rotating rod, enabling the grid membrane material to swing slightly when the wind force is large, playing a buffering effect.

Specific embodiments

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Please refer to Figures 1-3 , a sound insulation and noise reduction grid cloth curtain wall membrane structure, including a mounting seat 1, a mounting groove 101 arranged in the mounting seat 1, and a grid film material 8 arranged in the mounting groove 101. A fixing component 2 for fixing the grid film material 8 is arranged inside the mounting seat 1. A fixing seat 3 is fixedly connected to one side of the mounting seat 1. A rotating rod 4 is rotatably connected to the inner wall of the fixing seat 3. A connecting rod 5 is fixedly connected to the outer side of the rotating rod 4. A connecting component 6 is arranged at one end of the connecting rod 5. An mounting plate 7 is arranged on one side of the connecting component 6.

[0020] The mounting plate 7 is fixed on the mounting surface by bolts. The grid film material 8 is installed in the mounting groove 101 in the mounting seat 1. The grid film material 8 is fixed by the fixing component 2. The connecting component 6 enables the grid film material 8 to have a certain tension, and plays a buffering effect on the grid film material 8 when the wind force is large. And the connecting rod 5 is rotatably matched with the fixing seat 3 through the rotating rod 4, so that the grid film material 8 can swing slightly when the wind force is large.

[0021] It should be noted that: The grid membrane material 8 is made of PTFE grid membrane material, which can be purchased on the market. Compared with traditional curtain walls, the grid membrane curtain wall is lighter in weight, reducing the installation cost. From the perspective of energy conservation and environmental protection, it can reflect most of the sunlight, avoiding the heat brought by direct sunlight into the room and reducing the heat released secondarily after the wall absorbs heat, thus reducing the air-conditioning energy consumption; acoustically speaking, the grid membrane is also a good sound-absorbing material, which can improve the sound insulation and noise reduction effect of the building to a certain extent. Optically speaking, the light passing through the grid membrane into the building is converted from direct sunlight into soft diffused light.

[0022] Reference Figure 1 and Figure 2 As shown in the reference and, the fixing component 2 includes fixing screws 21 arranged on one side of the mounting base 1. The number of the fixing screws 21 is set to two. A pressing plate 22 is sleeved on the fixing screws 21. The pressing plate 22 is located in the mounting groove 101, and a nut 23 is screwed on the fixing screws 21.

[0023] After the grid membrane material 8 is placed in the mounting groove 101, by moving the pressing plate 22, one side of the pressing plate 22 is brought into contact with one side of the grid membrane material 8, and the pressing plate 22 is fixed by rotating the nut 23, so that the pressing plate 22 holds the grid membrane material 8 integrally, improving the stability of the grid membrane material 8.

[0024] Reference Figure 1 and Figure 2 As shown in the reference and, the fixing component 2 further includes a through groove 24 opened inside the pressing plate 22. A resisting plate 25 is inserted into the through groove 24. One side of the resisting plate 25 is fixedly connected with a resisting block 26. A resisting groove 27 for cooperating with the resisting block 26 is opened on one side of the mounting base 1. A fixing block 28 is integrally arranged on one side of the pressing plate 22. A tightening screw 29 is screwed into the fixing block 28, and one end of the tightening screw 29 abuts against one side of the resisting plate 25.

[0025] By rotating the tightening screw 29 in the fixing block 28, the end of the tightening screw 29 contacts one side of the resisting plate 25 and drives the resisting plate 25 to move in the through groove 24. The resisting plate 25 and the resisting block 26 on one side of it further press and fix one side of the grid membrane material 8. And after the resisting block 26 enters the resisting groove 27, it has a better fixing effect on the grid membrane material 8. Even in the case of strong wind, the grid membrane material 8 is not likely to be displaced.

[0026] Reference Figure 1 and Figure 2 As shown in the reference and, the connecting component 6 includes a connecting seat 61 arranged outside the connecting rod 5. A placing groove 62 for cooperating with the connecting rod 5 is opened inside the connecting seat 61. One end of the connecting rod 5 is fixedly connected with a fixing plate 63. A spring 64 is sleeved on the connecting rod 5. A sealing cover 65 is bolted and fixed on one side of the connecting seat 61. A sealing block 66 is integrally arranged on one side of the sealing cover 65.

[0027] When the grid membrane material 8 is affected by wind force, the connecting rod 5 and the fixing plate 63 move in the placement groove 62 and squeeze the spring 64, achieving a buffering effect. The sealing cover 65 and the sealing block 66 seal the connecting seat 61, preventing the spring 64 from rusting and facilitating the maintenance and replacement of the spring 64.

[0028] Reference Figure 3 As shown, the two ends of the spring 64 are respectively in contact with the inner wall of the connecting seat 61 and one side of the fixing plate 63.

[0029] The working principle of a sound-insulating and noise-reducing grid cloth curtain wall membrane structure provided by the present utility model is as follows:

[0030] During use, the mounting plate 7 is fixed to the mounting surface by bolts. The grid membrane material 8 is installed in the mounting groove 101 in the mounting seat 1. After the grid membrane material 8 is placed in the mounting groove 101, by moving the pressing plate 22, one side of the pressing plate 22 is brought into contact with one side of the grid membrane material 8, and the pressing plate 22 is fixed by rotating the nut 23, so that the pressing plate 22 presses the grid membrane material 8 as a whole, improving the stability of the grid membrane material 8. By rotating the pressing screw 29 in the fixing block 28, the end of the pressing screw 29 contacts one side of the pressing plate 25 and drives the pressing plate 25 to move in the through groove 24. The pressing plate 25 and the abutting block 26 on one side thereof further press and fix one side of the grid membrane material 8. And after the abutting block 26 enters the abutting groove 27, a better fixing effect on the grid membrane material 8 is achieved. Even in the case of strong wind, the grid membrane material 8 is not easily displaced. When the grid membrane material 8 is affected by wind force, the connecting rod 5 and the fixing plate 63 move in the placement groove 62 and squeeze the spring 64. At the same time, the connecting rod 5 is rotationally matched with the fixed seat 3 through the rotating rod 4, so that the grid membrane material 8 can swing slightly when the wind force is large, achieving a buffering effect.
