Description

Technical Field

[0001] This application relates to the field of building curtain wall technology, and in particular to a composite double-layer building curtain wall. Background Technology

[0002] Double-layer building curtain walls, also known as thermal aisle curtain walls, breathing curtain walls, ventilated curtain walls, energy-saving curtain walls, etc., consist of two facade structures, forming an air buffer layer between the interior and exterior. When the ventilation windows on both the interior and exterior curtain walls are open, ventilation can be achieved. When the ventilation windows on the exterior curtain wall are open and the glass windows on the interior are closed, airflow can flow along the air buffer layer between the interior and exterior, creating a chimney effect.

[0003] In existing technologies, common double-layer curtain wall systems are composed of several curtain wall units spliced ​​together. Each curtain wall unit includes an inner curtain wall and an outer curtain wall. A circulation space for air circulation is formed between the inner and outer curtain walls. The double-layer curtain wall system mainly relies on ventilation openings reserved on the layer structure or windows installed on the inner and outer curtain walls for ventilation. The ventilation efficiency is low, and it is difficult to meet the user's ventilation needs when the user needs to speed up the ventilation. Utility Model Content

[0004] To facilitate users in promptly improving indoor ventilation efficiency in a double-layer building curtain wall system when needed, this application provides a combined double-layer building curtain wall.

[0005] This application provides a combined double-layer building curtain wall using the following technical solution:

[0006] A combined double-layer building curtain wall includes an outer curtain wall and an inner curtain wall installed on the wall, wherein a circulation cavity for air circulation is formed between the outer curtain wall and the inner curtain wall, and an air exchange hole is provided on the inner curtain wall, the air exchange hole connecting the indoor space and the circulation cavity;

[0007] An installation frame is fixedly installed on the inner curtain wall, and a ventilation mechanism is detachably installed on the installation frame. The ventilation mechanism includes a ventilation fan, which is arranged opposite to the ventilation hole.

[0008] The ventilation mechanism is equipped with a sealing module for covering or exposing the ventilation holes.

[0009] By adopting the above technical solution, when indoor ventilation is required, the user can expose the ventilation hole through the closed module and start the ventilation fan. The operation of the ventilation fan can introduce the air in the circulation cavity into the room through the ventilation hole on the inner curtain wall to achieve indoor ventilation. The ventilation fan can improve the efficiency of indoor ventilation. When ventilation is over, the user can cover the ventilation hole again through the closed module and turn off the ventilation fan.

[0010] Preferably, the mounting frame includes a mounting base plate and two mounting side plates, and slots are provided on the opposite side walls of the two mounting side plates;

[0011] The ventilation mechanism includes a connecting plate, the ventilation fan is fixedly mounted on the connecting plate, and the two sides of the connecting plate are respectively embedded in the two slots;

[0012] The connecting plate has several threaded slots on both sides, and the two mounting side plates have several through holes for bolt rods to extend into.

[0013] By adopting the above technical solution, during the installation of the ventilation mechanism, the operator can insert the two sides of the connecting plate on the ventilation mechanism into the slots in the installation side plate, and the installation base plate supports the connecting plate from below; then, the operator can use the installation bolts to install and fix the connecting plate on the installation frame, thereby achieving the technical effect of detachable connection between the ventilation mechanism and the inner curtain wall.

[0014] Preferably, the connecting plate is provided with a sliding groove, the ventilation fan is fixedly installed on the side of the connecting plate away from the inner curtain wall, the air inlet of the ventilation fan is opposite to the ventilation hole, and the sealing module includes a baffle that is slidably installed on the connecting plate, the baffle being slidably disposed between the ventilation fan and the ventilation hole;

[0015] The enclosure module also includes a locking unit for locking the position of the baffle.

[0016] By adopting the above technical solution, when ventilation is required, the user can adjust the position of the baffle so that the air inlet of the ventilation fan is opposite to the ventilation hole; when ventilation is complete, the user can adjust the position of the baffle again so that the baffle blocks the ventilation hole and the ventilation fan, thus sealing the ventilation hole.

[0017] Preferably, a connecting block is fixedly installed on the side wall of the baffle away from the inner curtain wall, and a housing is fixedly installed on the side wall of the connecting plate away from the inner curtain wall. The bottom of the housing has a sliding hole for the connecting block to slide in or out.

[0018] A lever for adjusting the height of the baffle is fixedly installed on the side wall of the connecting block away from the inner curtain wall. An adjustment waist hole is provided on the housing, and the lever is slidably installed in the adjustment waist hole.

[0019] The housing has a first insertion hole through its two side walls, and the connecting block has a second insertion hole through its side walls. The locking unit includes a locking rod that passes through the first insertion hole and the second insertion hole and is positioned between the connecting block and the housing.

[0020] By adopting the above technical solution, when ventilation is required, the user can move the lever upward. The lever drives the baffle to slide upward in the groove through the connecting block to expose the ventilation hole, so that the ventilation hole is opposite to the air inlet of the ventilation fan. Then, the user can pass the locking lever through the first and second insertion holes, so that the locking lever is laterally limited between the connecting block and the housing, which can fix the position of the connecting block and the baffle, so that the ventilation hole is kept opposite to the ventilation fan. When the user has finished ventilating, the user can pull out the locking lever and drive the connecting block and the baffle downward through the lever, so that the baffle blocks the ventilation hole between the ventilation hole and the ventilation fan.

[0021] Preferably, the diameter of the second socket is larger than the diameter of the first socket.

[0022] By adopting the above technical solution, and by setting the diameter of the second socket to be larger than that of the first socket, it is convenient for the user to insert the locking rod into the first socket and the second socket when locking the baffle.

[0023] Preferably, the edges at both ends of the second socket are rounded.

[0024] By adopting the above technical solution, the rounded corners at both ends of the second socket can reduce the occurrence of collisions between the end of the locking rod and the edge of the second socket during the user's insertion of the locking rod, further improving the convenience of inserting the locking rod.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] Example

[0031] This application discloses a combined double-layer building curtain wall. (Refer to...) Figures 1-3 It mainly includes an outer curtain wall 1 and an inner curtain wall 2 installed on the wall. An air circulation cavity 3 is formed between the outer curtain wall 1 and the inner curtain wall 2 for air circulation. An air exchange hole 21 is opened on the inner curtain wall 2, and the air exchange hole 21 connects the indoor space and the air circulation cavity 3. An installation frame 22 is fixedly installed on the inner curtain wall 2. An air exchange mechanism 4 is detachably installed on the installation frame 22. The air exchange mechanism 4 includes an air exchange fan 41, which is arranged opposite to the air exchange hole 21. A sealing module 5 for covering or exposing the air exchange hole 21 is installed on the air exchange mechanism 4.

[0032] When indoor ventilation is needed, the user can expose the ventilation hole 21 through the sealing module 5 and start the ventilation fan 41. The operation of the ventilation fan 41 can introduce the air in the circulation cavity 3 into the room through the ventilation hole 21 on the inner curtain wall 2 to achieve indoor ventilation. The ventilation fan 41 can improve the efficiency of indoor ventilation. When ventilation is finished, the user can cover the ventilation hole 21 again through the sealing module 5 and turn off the ventilation fan 41.

[0033] Reference Figure 1 and Figure 2 The mounting frame 22 includes a mounting base plate 24 and two mounting side plates 23. Slots 25 are provided on the opposite side walls of the two mounting side plates 23. The ventilation mechanism 4 includes a connecting plate 42. The ventilation fan 41 is fixedly mounted on the connecting plate 42. The two sides of the connecting plate 42 are respectively embedded in the two slots 25. Several threaded slots 43 are provided on both sides of the connecting plate 42. Several through holes 26 for bolt rods to extend into are provided on the two mounting side plates 23.

[0034] During the installation of the ventilation mechanism 4, the operator can insert the two sides of the connecting plate 42 on the ventilation mechanism 4 into the slots 25 in the mounting side plate 23, and the mounting base plate 24 is supported under the connecting plate 42. Subsequently, the operator can use the mounting bolts to install and fix the connecting plate 42 on the mounting frame 22, so as to achieve the technical effect of detachable connection between the ventilation mechanism 4 and the inner curtain wall 2.

[0035] Reference Figure 2 and Figure 3 The connecting plate 42 is provided with a sliding groove 44. The ventilation fan 41 is fixedly installed on the side of the connecting plate 42 away from the inner curtain wall 2. The air inlet end of the ventilation fan 41 is opposite to the ventilation hole 21. The sealing module 5 includes a baffle 51 that is slidably installed on the connecting plate 42. The baffle 51 is slidably disposed between the ventilation fan 41 and the ventilation hole 21. The sealing module 5 also includes a locking unit for locking the position of the baffle 51.

[0036] When ventilation is required, the user can adjust the position of the baffle 51 so that the air inlet of the ventilation fan 41 is opposite to the ventilation hole 21. When ventilation is complete, the user can adjust the position of the baffle 51 again so that the baffle 51 blocks the ventilation hole 21 and the ventilation fan 41, thus sealing the ventilation hole 21.

[0037] Reference Figure 2 and Figure 3 A connecting block 52 is fixedly installed on the side wall of the baffle 51 away from the inner curtain wall 2. A housing 45 is fixedly installed on the side wall of the connecting plate 42 away from the inner curtain wall 2. A sliding hole 46 is provided at the bottom of the housing 45 for the connecting block 52 to slide in or out. A lever 53 for adjusting the height of the baffle 51 is fixedly installed on the side wall of the connecting block 52 away from the inner curtain wall 2. An adjustment waist hole 47 is provided on the housing 45. The lever 53 is slidably installed in the adjustment waist hole 47.

[0038] The housing 45 has a first insertion hole 48 through its two side walls, and the connecting block 52 has a second insertion hole 54 through its side walls. The locking unit includes a locking rod 55, which passes through the first insertion hole 48 and the second insertion hole 54 and is positioned between the connecting block 52 and the housing 45.

[0039] When ventilation is needed, the user can move the lever 53 upwards. The lever 53 drives the baffle 51 to slide upwards in the groove 44 via the connecting block 52 to expose the ventilation hole 21, so that the ventilation hole 21 is opposite to the air inlet end of the ventilation fan 41. Then, the user can pass the locking lever 55 through the first insertion hole 48 and the second insertion hole 54, so that the locking lever 55 is laterally limited between the connecting block 52 and the housing 45, which can fix the position of the connecting block 52 and the baffle 51, so that the ventilation hole 21 remains opposite to the ventilation fan 41. When the user has finished ventilating, the user can pull out the locking lever 55 and drive the connecting block 52 and the baffle 51 downwards via the lever 53, so that the baffle 51 blocks the ventilation hole 21 between the ventilation hole 21 and the ventilation fan 41, thus blocking the ventilation hole 21.

[0040] It should be noted that, in this embodiment, the diameter of the second socket 54 is larger than the diameter of the first socket 48. Furthermore, the edges at both ends of the second socket 54 are rounded.

[0041] By setting the diameter of the second socket 54 to be larger than that of the first socket 48, it is easier for the user to insert the locking rod 55 into the first socket 48 and the second socket 54 when locking the baffle 51.

[0042] The rounded corners at both ends of the second socket 54 reduce the chance of the end of the locking rod 55 colliding with the edge of the second socket 54 during the insertion of the locking rod 55, thus further improving the ease of inserting the locking rod 55.

[0043] The implementation principle of a combined double-layer building curtain wall in this application embodiment is as follows: When indoor ventilation is required, the user can expose the ventilation hole 21 through the sealing module 5 and start the ventilation fan 41. The operation of the ventilation fan 41 can introduce the air in the circulation cavity 3 into the room through the ventilation hole 21 on the inner curtain wall 2 to achieve indoor ventilation. The ventilation fan 41 can improve the efficiency of indoor ventilation. When ventilation is finished, the user can cover the ventilation hole 21 again through the sealing module 5 and turn off the ventilation fan 41. When ventilation is needed, the user can move the lever 53 upwards. The lever 53 drives the baffle 51 to slide upwards in the groove 44 via the connecting block 52 to expose the ventilation hole 21, so that the ventilation hole 21 is opposite to the air inlet end of the ventilation fan 41. Then, the user can pass the locking lever 55 through the first insertion hole 48 and the second insertion hole 54, so that the locking lever 55 is laterally limited between the connecting block 52 and the housing 45, which can fix the position of the connecting block 52 and the baffle 51, so that the ventilation hole 21 remains opposite to the ventilation fan 41. When the user has finished ventilating, the user can pull out the locking lever 55 and drive the connecting block 52 and the baffle 51 downwards via the lever 53, so that the baffle 51 blocks the ventilation hole 21 between the ventilation hole 21 and the ventilation fan 41, thus blocking the ventilation hole 21.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
