Description

Technical Field

[0001] The present invention relates to the technical field of double - layer curtain walls, and specifically to a composite - structure external - ventilation double - layer curtain wall. Background Art

[0002] The double - layer curtain wall, also known as a hot - channel curtain wall, a breathing curtain wall, a ventilation curtain wall, an energy - saving curtain wall, etc., is composed of an inner and an outer layer of facade structures, forming an air buffer layer between the interior and the exterior. The outer layer can be composed of a framed, semi - framed or point - supported curtain wall, and the inner layer can be composed of a framed, semi - framed curtain wall, or doors and windows with opening fans and maintenance passages. It can also have glass facades on both sides of an independent support structure, forming a double - layer facade structure with a relatively small spatial distance. Due to the usage characteristics of the double - layer curtain wall, it has become one of the common structures in modern architecture.

[0003] However, during the use of the double - layer curtain wall, the structure for ventilation and air change is generally a louver. Since the double - layer curtain wall is generally installed at a relatively high floor height, it is greatly affected by the wind speed. When the wind speed is high, a large amount of noise will be generated during the use of the double - layer curtain wall. When the double - layer curtain wall encounters strong winds during use, it will generate large pressures and suctions on the double - layer curtain wall, causing the inner curtain wall to bear additional loads and threatening the structural stability, endangering the safety of the people inside the building and surrounding facilities. Thus, the most ideal state is to avoid excessive wind from entering the double - layer curtain wall, thereby ensuring the safety of the double - layer curtain wall during use. Traditional double - layer curtain walls do not have a structure to reduce the amount of wind entering the double - layer curtain wall when the wind is strong, which affects the safety of the device during use. In addition, during winter, condensation water will be generated on the inner layer of the double - layer curtain wall. These condensation waters not only affect the light transmittance of the curtain wall but also cause dirt on the surface of the double - layer curtain wall, bringing problems of cleaning the curtain wall to the users and greatly affecting the adaptability of the double - layer curtain wall.

[0004] To solve the above problems, a composite - structure external - ventilation double - layer curtain wall is needed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a composite - structure external - ventilation double - layer curtain wall, which solves the problem that the traditional double - layer curtain wall cannot adjust the air inlet according to the wind speed during use, avoiding affecting the ventilation and air - change effect of the double - layer curtain wall, and avoiding problems such as large noise or damage to the internal structure caused by the inability to adjust the wind speed. It ensures that during the ventilation and air - change process, the inner glass surface can be blown obliquely, avoiding the problem that the condensation water on the glass affects the use of the device and ensuring the adaptability of the device.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 10 , a composite structure type external ventilation double-layer curtain wall in this embodiment includes two standard connecting pieces 1. The fronts of the two standard connecting pieces 1 are jointly fixed with an air inlet frame 3 through an L-shaped connecting plate 2. The opposite sides of the two standard connecting pieces 1 are jointly installed with a first glass wall 4 through a plurality of first fixing pieces 6. A ventilation window 5 is provided in the middle of the first glass wall 4. The front side of the top surface of the lower L-shaped connecting plate 2 is installed with a second glass wall 8 through a plurality of second fixing pieces 7. An air outlet louver 9 is jointly fixed on the top surface of the second glass wall 8 and the bottom surface of the upper standard connecting piece 1.

[0036] A cleaning port 10 is provided at the center of the top surface of the two L-shaped connecting plates 2, and a windshield plate 13 for inclined wind guiding is fixedly installed inside the cleaning port 10, an N-shaped cavity 11 is provided on the upper side of the inner wall of the two air inlet frames 3, and an adjustment mechanism for pushing and adjusting is provided on the upper side of the inner wall of the N-shaped cavity 11, and the windshield plate 13 is a folded line corrugated plate body, and the wave pitch of the windshield plate 13 is set to β, and 5 cm ≤ β ≤ 15 cm. The corrugated plate structure of the windshield plate 13 can ensure that the windshield plate 13 has an efficient wind guiding effect, and the folded line design can change the direction of the wind at multiple corners when encountering the corrugated plate, thereby effectively guiding the wind to the target direction and realizing an efficient air supply function. In this way, the wind guiding effect of the windshield plate 13 can avoid the influence of condensation on the surface of the first glass wall 4. The problem of light transmittance of the first glass wall 4 can be solved by using the zigzag corrugated structure of the wind shield 13, which can also enhance air disturbance. When wind passes through the zigzag corrugated structure, complex turbulence will be generated at the depressions and protrusions of the corrugations. This turbulence can enhance the degree of air disturbance. The air disturbance can increase the evaporation of condensed water on the surface of the first glass wall 4, and can effectively take away heat to avoid affecting the normal use of the first glass wall 4. In addition, the zigzag corrugated structure of the wind shield 13 can also disperse and change the flow direction of wind, thereby reducing the noise generated by wind directly hitting the surface of an object. The zigzag corrugated structure can also make the wind shield 13 as a whole have higher strength and stability. Compared with a flat structure, the corrugated plate can better disperse the pressure when subjected to wind force and is not easily deformed or damaged.

[0037] The adjusting mechanism comprises a sliding plate 15 slidably mounted on the upper side of the inner wall of the N-shaped cavity 11, and a trapezoidal push block 16 is fixedly mounted in the middle of the top surface of the sliding plate 15, and an adjusting rack 17 is fixedly mounted on both sides of the bottom surface of the sliding plate 15, and the bottom surface of the adjusting rack 17 is sleeved with a spring 30 through an embedded first guide rod 29, and two corresponding adjusting racks 17 are fixedly mounted with an adjusting rod 19 through a meshing adjusting gear 18, and an adjusting plate 20 is fixedly mounted on the lever arm of the adjusting rod 19, and a transmission rod 22 is rotatably mounted on the surface of the standard connecting member 1 and the surface of the air inlet frame 3 through a fixed plate 21, and a transmission mechanism for power transmission is provided on the lower side of the surface of the transmission rod 22, and the transmission mechanism comprises a plurality of blades 23 fixedly mounted on the lower side of the surface of the transmission rod 22, and a first pulley 24 is fixedly mounted on the top surface of the transmission rod 22, and the first pulley 24 is rotatably connected to a second pulley 26 through a belt 25, and an extrusion mechanism for extruding the trapezoidal push block 16 is provided on the top surface of the second pulley 26;

[0038] The extrusion mechanism includes a round block 27 fixedly installed on the top surface of the second pulley 26. A number of moving cavities 28 are formed inside the round block 27. The inner walls of the number of moving cavities 28 are slidably installed with extrusion rods 32 through fixed second guide rods 31. The rod arms of the extrusion rods 32 are slidably connected to the inner walls of the moving cavities 28 through limit ring blocks 33. The surfaces of the limit ring blocks 33 are fixedly connected with extrusion tension springs 34, and the extrusion tension springs 34 are sleeved on the rod arms of the second guide rods 31.

[0039] Among them, the two standard connectors 1 are arranged vertically aligned. A number of adjusting rods 19 are arranged through the inside of the N-shaped cavity 11, and the opposite ends of the adjusting rods 19 are rotatably connected to the opposite sides inside the N-shaped cavity 11. The lengths of the number of adjusting plates 20 match the inner wall length of the air inlet frame 3, and the adjusting plates 20 are located inside the air inlet frame 3. The bottom surface of the second pulley 26 is rotatably connected to the top surface of the fixed plate 21 through a rotating shaft. The lower ends of the number of corresponding first guide rods 29 are fixedly connected to the lower side of the inner wall of the N-shaped cavity 11. One ends of the number of extrusion tension springs 34 are respectively fixedly connected to the inner walls of the corresponding moving cavities 28. The number of second guide rods 31 are arranged to be embedded in the extrusion rods 32.

[0040] Specifically, the two standard connectors 1 are both Z-shaped plate structures. The first fixing member 6 and the second fixing member 7 both include I-shaped steel columns 101 and glass claws 102 riveted to the inner walls of the I-shaped steel columns 101. The length of the I-shaped steel column 101 in the first fixing member 6 is lower than that of the I-shaped steel column 101 in the second fixing member 7. A number of fan blades 23 are arranged at equal intervals around the circumference of the rod arm of the transmission rod 22. The number of moving cavities 28 are arranged in an annular array inside the round block 27. The number of extrusion rods 32 are arc-headed rod bodies. The materials of the two L-shaped connecting plates 2 are steel, the materials of the two air inlet frames 3 and the air outlet louvers 9 are both aluminum alloy. The materials of the first glass wall 4 and the second glass wall 8 are tempered transparent glass and chrome film glass respectively.

[0041] It should be noted that ceramic sealing strips 37 are provided on the top surface of the lower standard connector 1 in front of the first glass wall 4 and at the front corners of the top surface of the lower standard connector 1. The ceramic sealing strips 37 are all arc-shaped, which can better conduct water drainage operations. A water guide slope 38 is fixedly installed between the two second fixing members 7 on the front side of the top surfaces of the two L-shaped connecting plates 2. A plurality of air vents 39 are formed on the top surface of the water guide slope 38 and the top surfaces of the L-shaped connecting plates 2 together.

[0042] It should be noted that the double - layer curtain wall, which is the whole of this application, has good heat insulation, sound insulation, ventilation and other properties, and is suitable for various sites with high requirements for building environment and energy conservation, such as commercial office buildings, cultural and educational buildings, medical buildings, high - end residential buildings, etc. Since the double - layer curtain wall has a wide range of applications, its location can be high or low. When this device is used at a lower shock - absorbing position or a position with a smaller wind speed, under the push of the spring 30, the adjusting rack 17 is in the uppermost position. In this way, the adjusting rack 17 drives the adjusting plate 20 fixed to the adjusting rod 19 on the adjusting gear 18 to be in the optimal opening position, that is, the adjusting plate 20 is at a 45 - degree angle position, which can also ensure the overall ventilation effect;

[0043] When the whole device is set at a higher height or a position with a larger wind speed, the greater the distance that the extrusion rod 32 moves away from the round block 27 under the action of centrifugal force. Then, under the extrusion and push of several extrusion rods 32, the trapezoidal push block 16 will push the sliding plate 15 and the adjusting rack 17 downward. During the downward movement of the adjusting rack 17, the adjusting rack 17 drives the adjusting plates 20 fixed to the adjusting rod 19 on the adjusting gear 18 to approach each other. As a result, the amount of air entering the device through the air inlet frame 3 is reduced. Thus, when the wind speed is too large, the amount of air entering the device is reduced. The amount of gas entering the device becomes less, and thus there will be no problem that a large pressure and suction are generated inside the device, which will cause the device to bear an additional load and threaten the structural stability, endangering the safety of the personnel inside the building and the surrounding facilities. Moreover, the air inlet structures such as the wind - blocking plate 13 of the device are all made of high - strength aluminum alloy, which can ensure the structural safety during the use of the device.

[0044] The working principle of the above - mentioned embodiment is as follows:

[0045] When the device is in use, the standard connector 1 is a part of the building main body, and the first glass wall 4 is the structural enclosure of the building. When the device is in use, the wind flows into the air inlet frame 3. In the initial position of the air inlet frame 3, under the push of the spring 30, the adjusting rack 17 is in the uppermost position. In this way, the adjusting rack 17 drives the adjusting plate 20 fixed to the adjusting rod 19 on the adjusting gear 18 to be in the optimal opening setting;

[0046] When the wind enters the air inlet frame 3, it will drive the transmission rod 22 in the fan blade 23 to rotate, and the fan blade 23 will blow air into the cleaning port 10. In this way, the wind passing through the cleaning port 10 will be obliquely blocked by the wind - blocking plate 13, and the wind will be blown towards the surface of the first glass wall 4 to ensure the air - drying effect of the glass;

[0047] While the first pulley 24 is rotating, it drives the circular block 27 on the second pulley 26 to rotate through the belt 25. During the rotation of the circular block 27, centrifugal force will be generated. In this way, the greater the rotation speed of the circular block 27, the greater the wind speed entering the device can be reflected. The faster the circular block 27 rotates, the greater the distance that the extrusion rod 32 moves away from the circular block 27 under the action of centrifugal force. Furthermore, under the extrusion and push of several extrusion rods 32, the trapezoidal push block 16 will push the sliding plate 15 and the adjustment rack 17 downward. During the downward movement of the adjustment rack 17, the adjustment rack 17 drives the adjustment plate 20 fixed to the adjustment rod 19 on the adjustment gear 18 to approach each other, thereby reducing the air volume passing through the air inlet frame 3, and thus achieving the effect that when the wind speed is too high, the air intake entering the device is reduced. Through the above structure, when the wind speed is relatively high, the gas entering the device will become less, and thus there will be no problem that a large pressure and suction force are generated inside the device, so that the device will bear an additional load and the structural stability will be threatened, endangering the safety of the personnel inside the building and the surrounding facilities. Moreover, the air inlet structures such as the wind baffle 13 of the device are all made of high-strength aluminum alloy material, which can ensure the structural safety during the use of the device. On the contrary, when the air volume decreases, it will move in the reverse direction of the above structure under the push of the spring 30, thereby increasing the air volume passing through the air inlet frame 3. And when the air volume is relatively small, the rotation speed of the pulley structure will also decrease. In this way, under the pulling force of the extrusion spring 34, the extrusion rod 32 will retract into the circular block 27, so that the thrust of the spring 30 can better push the structure and make the air volume enter better. During the process of changing the air volume size of this device, and thus controlling the size of the air intake, it can ensure that the device is always in a better gas circulation, and can blow and dry the glass wall structure surrounded by the structure while rotating, avoiding the influence problem of condensed water and ensuring the normal use function of the device. The innovative structure of this device will not be elaborated too much on the prior art.

[0048] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle will not be elaborated too much in this embodiment.
