Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular belongs to a reconstruction structure of an existing building exterior wall. Background Art

[0002] Green building energy storage technology requires the storage of electrical energy, but finding special space inside the building will waste the building's usable area. Currently, there is a technical demand to install battery installation equipment in the building's exterior walls (including non-load-bearing surrounding walls and load-bearing surrounding walls). Such building exterior walls allow the battery modules to be disassembled and installed in the building's exterior walls.

[0003] At present, in the process of renovating the exterior walls of buildings, the exterior walls are formed by masonry bricks combined with insulation layers and waterproof layers, and then battery components are installed on the walls. Although the wall structure meets the needs of green building energy storage, such wall structures cannot achieve ventilation of indoor and outdoor air. When the wall structure is used for indoor and outdoor air exchange, windows need to be opened on the wall structure for ventilation.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes a reconstruction structure for the exterior wall of an existing building. The exterior wall structure sets a ventilation section between the inner wall panel and the outer wall panel. The air intake and exhaust of the first folding bellows and the second folding bellows are controlled by a linkage component in the ventilation section, thereby forming heat exchange between indoor and outdoor areas, which is used to help reduce indoor heat load (floor heating) or cold load (air conditioning), reduce energy loss, and greatly improve the functionality and practicality of the building exterior wall; at the same time, the introduction of noise reduction components in the exterior wall structure reduces the impact of external noise on the indoor environment, providing users with a quieter and more comfortable living or working environment; the exterior wall structure of the present invention has a compact structure, which ensures the stability and reliability of the overall structure. At the same time, the exterior wall structure is easy to install and maintain, which reduces the cost and difficulty of reconstruction and has high economy and feasibility.

[0016] Furthermore, the linkage assembly in the present exterior wall structure realizes the stable connection and flexible adjustment of the first folding bellows and the second folding bellows through the cooperation of the M-shaped metal clip and the first clamping plate. The M-shaped metal clip is arranged on the long connecting plate, which not only ensures the stability of the structure, but also facilitates installation and disassembly. The fit between the first clamping plate and the inner wall of the M-shaped metal clip enhances the connection tightness between the bellows and effectively prevents the bellows from shaking or separating during use. The setting of the first connecting rod and the second connecting rod facilitates the connection of the drive assembly, so that the drive assembly can accurately transmit power and control the folding and unfolding of the bellows. The second connecting side plate vertically arranged between the noise reduction assembly and the long connecting plate not only provides an installation space for the drive assembly, but also further enhances the stability of the entire structure, improves the reliability and durability of the exterior wall structure, and facilitates later maintenance and reduces the cost of use.

[0017] Furthermore, the combined use of the M-shaped metal clip and the first clamping plate in the present exterior wall structure enables the first folding bellows and the second folding bellows to be stably compressed or expanded, ensuring the stability and safety of the ventilation unit during operation. The M-shaped metal clip provides an automatic reset function for the ventilation unit through changes in its own elasticity and then cooperates with a reset spring. When the driving component stops working, the reset spring can push the M-shaped metal clip and the folding bellows back to their initial positions, switching the operating states of the first folding bellows and the second folding bellows, thereby improving the degree of automation of the ventilation unit and reducing energy consumption and maintenance costs.

[0018] Furthermore, the provision of the heat-insulating curtain in the exterior wall structure effectively reduces the heat transfer between the noise reduction components and the battery mounting plate, thereby improving the thermal insulation performance of the entire exterior wall structure. Under extreme weather conditions, such as high temperatures in summer or severe cold in winter, the heat-insulating curtain can significantly reduce indoor temperature fluctuations, thereby improving the comfort of the living or working environment and reducing energy consumption.

[0019] Furthermore, the rolling-up and unrolling assembly in the exterior wall structure enables the thermal insulation curtain to be easily unfolded and folded, and the operation is simple and quick. The reel serves as the main supporting structure of the thermal insulation curtain and is horizontally installed on the wall between the noise reduction assembly and the battery mounting plate, ensuring the stability and reliability of the thermal insulation curtain. The introduction of the rolling-up motor realizes the automatic control of the thermal insulation curtain. The user can easily control the unfolding and folding of the thermal insulation curtain through a switch or a remote control, thereby improving the convenience of use.

[0020] Furthermore, the double-layer noise reduction film board in the present exterior wall structure effectively blocks the propagation path of external noise, and forms a barrier to sound propagation through the air layer between the two layers of film boards, thereby greatly reducing the penetration ability of noise.

Alternatively, the first noise reduction film plate 51 and the second noise reduction film plate 52 are staggered on both sides of the ventilation part, and the spacing between the first noise reduction film plate 51 and the second noise reduction film plate 52 is in the range of 8 cm to 20 cm, so that an effective air layer is formed between the first noise reduction film plate 51 and the second noise reduction film plate 52, which has a blocking and attenuation effect on sound waves, thereby enhancing the noise reduction effect of the device and preventing the film plates from interfering with each other due to too small a spacing or reducing the noise reduction effect due to too large a spacing; the first noise reduction film plate 51 is arranged near the outer wall panel 2; the second noise reduction film plate 52 is arranged near the battery mounting plate 14 The first noise reduction film plate 51 and the second noise reduction film plate 52 are connected to the first bottom plate 54 at the bottom ends, and the first bottom plate 54 is fixed to the floor beam or floor slab by screws. Two second clamping plates 53 are symmetrically arranged on the upper end surface of the first bottom plate 54. The first noise reduction film plate 51 and the second noise reduction film plate 52 are fixed by rivet connection or adhesive connection between the two second clamping plates 53. The first noise reduction film plate 51 and the second noise reduction film plate 52 are used to absorb external noise. The first noise reduction film plate 51 is mainly used for medium and low frequency noise absorption, and the second noise reduction film plate 52 is mainly used for high frequency noise absorption. At the same time, M-type The metal clip 3 tends to return to its initial position under the action of the reset spring 37 and the elasticity of the M-shaped metal clip 3 itself. The second connecting rod 32 will swing slightly with the M-shaped metal clip 3 during the reset process. At this time, the second connecting rod 32 will hit the first noise reduction film plate 51 or the second noise reduction film plate 52, and the force of the second connecting rod 32 hitting the first noise reduction film plate 51 or the second noise reduction film plate 52 is less than 2N. The collision of the second connecting rod 32 with the first noise reduction film plate 51 or the second noise reduction film plate 52 will generate sound waves, which will be transmitted in the air to interfere with the noise transmitted from the outside to the room, further assisting in noise reduction. At the same time, when the first noise reduction film plate 51 and the second noise reduction film plate 52 are installed, a sufficiently large distance can be reserved between the first noise reduction film plate 51 and the second noise reduction film plate 52. When the M-shaped metal clamp 3 rotates or is reset under the action of the reset spring 37, the second connecting rod 32 will not hit the first noise reduction film plate 51 and the second noise reduction film plate 52, thereby improving the service life of the first noise reduction film plate 51 and the second noise reduction film plate 52.

[0040] In this embodiment, the first noise reduction film plate 51 is a natural rubber film plate with a thickness ranging from 1 mm to 4 mm and a porosity of 20%, which can effectively absorb noise in the medium and low frequency bands; the second noise reduction film plate 52 is a polyester film plate with a thickness ranging from 0.1 mm to 1 mm and a porosity of 40%, which has a good attenuation effect on high-frequency noise and also helps to scatter and interfere with sound, further enhancing the noise reduction effect and enhancing the flexibility and adaptability of the device.

[0041] The following is a further explanation of the exterior wall structure through its working principle: In the summer environment, when the indoor temperature is high and the outdoor temperature is low, the reel is rotated by the reeling motor to reel in the heat insulation curtain 15, and the heat insulation curtain 15 is kept in this state, and then the indoor and outdoor air are exchanged in the following two ways; One way is to use the natural state, so that the high-temperature air in the room enters the position where the battery mounting plate 14 is located through the first ventilation hole 11, then flows to the position of the outer wall panel 2 through the second ventilation hole 19, and flows to the outside through the third ventilation hole 20 on the outer wall panel 2. The low-temperature air outside flows to the battery mounting plate 14 through the third ventilation hole 20, then flows to the position of the inner wall panel 1 through the second ventilation hole 19, and finally enters the room through the first ventilation hole 11, so as to realize the air exchange between the indoor and outdoor. Another way is to drive the motor to rotate the rotating rod 33, and then the cam 35 will cause the M-shaped metal clamp 3 to rotate around the long connecting plate 4, the folding bellows A and the folding bellows D are compressed, and the folding bellows B and the folding bellows C are unfolded. The folding bellows A discharges the air inside it to the position between the noise reduction component and the outer wall panel 2 through the first ventilation hose 43, and the folding bellows D releases the air inside it to the area close to the room through the first ventilation hose 43. At the same time, the folding bellows C draws air from the area close to the room through the second ventilation hose 44, and the folding bellows B draws air from the outside of the outer wall panel 2 through the second ventilation hose 44, thereby forming heat exchange between indoor and outdoor, which helps to reduce the indoor temperature and thus reduce the indoor cooling load. When the drive motor is working, if the battery module 18 supplies power to the drive motor, heat energy will be generated, and the drive motor will also generate heat energy. These two parts of heat energy are mainly accumulated between the battery mounting plate 14 and the inner wall panel 1. The two parts of heat energy will also be exchanged with the lower temperature air outside by the folding bellows 39. At the same time, the folding bellows 39 will also draw in the colder air outside and release it between the battery mounting plate 14 and the second noise reduction film plate 52. Part of the heat will be exchanged between the second noise reduction film plate 52 and the inner wall panel 1. The heat exchange between indoor and outdoor is realized through this exterior wall structure, which helps to reduce the indoor cold load. When the indoor temperature is close to the outdoor temperature, by starting the roll-up motor and keeping the drive motor turned off, the heat insulation curtain 15 is unfolded, so that the indoor and outdoor air temperatures are almost no longer exchanged.

[0042] In winter, when the indoor temperature is high and the outdoor temperature is low, the roll-up motor is turned on and the drive motor is kept off to unfold the heat insulation curtain 15 to reduce the heat exchange between indoor and outdoor, thereby reducing the indoor heat load.
