[0002] Curtain walls are the exterior protective walls of buildings. Because they hang from the main structure like a curtain, they are also called suspended walls. Commonly used in modern large and high-rise buildings, curtain walls offer both decorative and lightweight features. Composed of a structural frame and inlaid panels, they are a building envelope that does not bear the main structural load.

[0003] During curtain wall installation, after the panels are in place, sealant must be injected into the joints between adjacent panels to create a complete, waterproof, and airtight enclosure system. The quality of the sealant injection directly determines the curtain wall's waterproofing performance. However, the quality of this process is highly dependent on the skill level of the construction workers, resulting in inconsistent curtain wall waterproofing performance. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also refer to Figures 1 to 4 The curtain wall structure of the present invention is described below. A curtain wall structure includes a plate unit 10, an installation unit 20, and a connection unit 30; the plate unit 10 includes an outer plate 101 and a connection seat 102 arranged opposite to each other in the horizontal direction, and a plurality of connection plates 103 fixed between the outer plate 101 and the connection seat 102. The connection plate 103 is provided with a plurality of injection holes 1031, and the ends of the injection holes 1031 are sealed with a wrapping film. An extrusion column 1032 is provided in the injection hole 1031. The extrusion column 1032 is slidably connected to the connection plate 103 in the up-down direction. Sealant is placed between the pressure column 1032 and the wrapping film; the installation unit 20 is connected to the structural frame 50, and is used to fix the structural frame 50 to the connecting seat 102; the connecting unit 30 includes a movable plate 301 corresponding one to the connecting plate 103, a telescopic member 302 fixed between the movable plate 301 and the connecting plate 103, and a driving assembly provided on the connecting seat 102, the moving direction of the telescopic member 302 is perpendicular to the plate surface of the corresponding connecting plate 103, and the driving assembly is used to drive the movable plate 301 to move close to the connecting plate 103.

[0020] It should be noted that the structural frame 50 is a keel frame, which is a conventional choice for curtain wall construction and will not be described in detail in this application.

[0021] The curtain wall structure provided in this embodiment first fixes the connecting seat 102 on the structural frame 50 through the installation unit 20, and then uses the driving component to make the movable plate 301 squeeze the corresponding extrusion column 1032, thereby squeezing out the sealant in the injection hole 1031, thereby completing the installation of one plate unit 10; when installing the next plate unit 10, the above steps are repeated, but at this time the wrapping films on the two adjacent connecting plates 103 in the two plate units 10 will squeeze each other, causing the wrapping films to rupture, so that the sealant will be injected into the space between the two adjacent connecting plates 103 in the two plate units 10; the above steps are repeated until the curtain wall construction is completed.

[0022] Compared with the prior art, the driving assembly drives the movable plate 301 close to the corresponding connecting plate 103, so that the movable plate 301 squeezes the extrusion column 1032, so that the extrusion column 1032 squeezes the sealant, thereby squeezing the sealant out of the injection hole 1031. If the plate unit 10 has been installed on one side of the corresponding connecting plate 103, the two protruding wrapping films will also squeeze each other, so that the wrapping film will be squeezed and the sealant will flow between the two adjacent connecting plates 103, thereby completing the gluing operation. If the plate 201 material unit 10 is not installed on one side of the corresponding connecting plate 103, the wrapping film is only subjected to the extrusion force of the extrusion column 1032, and the wrapping film will not be squeezed. The present invention uses mechanical extrusion to inject the sealant between the two connecting plates 103. The multi-point glue injection forms a continuous sealing layer between the two adjacent connecting plates 103, without relying on the operating experience of the staff, and ensures the waterproof performance of the curtain wall.

[0023] In some embodiments, see Figure 2 The connecting seat 102 is provided with a plurality of mounting grooves 1021 , and the mounting grooves 1021 correspond one-to-one to the edge lines of the connecting seat 102 , and the inner wall of the mounting groove 1021 is provided with a limiting groove 1022 .

[0024] The mounting unit 20 includes a plurality of mounting plates 201, a limiting column 202, and an elastic member 203; the plurality of mounting plates 201 are fixedly connected to the structural frame 50, the mounting plates 201 are plugged and adapted in a one-to-one correspondence with the mounting grooves 1021, and the mounting plates 201 are provided with a storage cavity; the limiting column 202 is arranged in the storage cavity, the limiting column 202 is slidably connected to the mounting plate 201, the moving direction of the limiting column 202 is perpendicular to the plate surface of the mounting plate 201, the limiting column 202 is plugged and adapted with the limiting groove 1022, and an extrusion surface is provided on the side of the limiting column 202 away from the structural frame 50; the elastic member 203 is fixed between the mounting plate 201 and the limiting column 202, the elastic member 203 has a pre-tightening force that causes the limiting column 202 to move away from the mounting plate 201, and the elastic member 203 can be a spring or a spring rod.

[0025] The staff secures the mounting plate 201 to a preset position on the structural frame 50, then moves the plate 301 material unit 10 so that the mounting plate 201 is inserted into the corresponding mounting slot 1021. Before the mounting plate 201 is inserted into the mounting slot 1021, the extrusion surface of the limiting post 202 is pressed by the connecting seat 102, causing the limiting post 202 to retract into the receiving cavity. After the mounting plate 201 is fully inserted into the mounting slot 1021, the receiving cavity and the limiting slot 1022 are aligned. Then, the elastic member 203 releases its elastic force, inserting the limiting post 202 into the limiting slot 1022.

[0026] The vertical plugging direction of the limiting column 202 and the limiting groove 1022 generates a lateral restraining force, firmly anchoring the plate unit 10 to the structural frame 50, and realizing a one-step installation of "plugging and locking".

[0027] In some embodiments, see Figure 2 and Figure 3 The driving assembly includes a driving roller 303, a driving sleeve 304, a plurality of transmission plates 305 and a transmission assembly; the driving roller 303 is slidably connected to the connecting seat 102, and the moving direction of the driving roller 303 is perpendicular to the seat surface of the connecting seat 102; the driving sleeve 304 is arranged on the outer periphery of the driving roller 303, the driving sleeve 304 is screwed to the driving roller 303, and the driving sleeve 304 is also rotatably connected to the connecting seat 102, and the driving sleeve 304 rotates with the axial direction of the driving roller 303 as the rotation axis; a plurality of transmission plates 305 correspond to the movable plates 301 one by one, the transmission plates 305 are fixed to the outer wall of the driving sleeve 304, and the transmission plate 305 is provided with a force-bearing surface 3051 that abuts against the corresponding movable plate 301; the transmission assembly is arranged between the driving sleeve 304 and the limiting column 202, so that the driving sleeve 304 is driven to rotate during the process of the limiting column 202 being inserted into the limiting groove 1022.

[0028] A transmission cavity 1023 is provided in the connecting seat 102, and the transmission assembly and the drive sleeve 304 are both provided in the transmission cavity 1023; the transmission assembly includes a transmission column 306 and a transmission sleeve 307; the transmission column 306 is passed through the transmission cavity 1023 and the limiting groove 1022, and the transmission column 306 is slidably connected to the connecting seat 102 along the moving direction of the limiting column 202, and the outer wall of the transmission column 306 is fixedly connected with a transmission block 3061; the transmission sleeve 307 is provided in the transmission cavity 1023 and on the outer periphery of the transmission column 306, and is also rotatably connected to the connecting seat 102, and is transmission-connected to the drive sleeve 304, and the transmission sleeve 307 and the drive sleeve 304 are transmission-connected by a bevel gear set, and the transmission sleeve 307 rotates with the axial direction of the transmission column 306 as the rotation axis, and the inner wall of the transmission sleeve 307 is spirally provided with a transmission groove 3071 which is slidingly adapted to the transmission block 3061.

[0029] When the limiting column 202 is inserted into the limiting groove 1022, the limiting column 202 squeezes the transmission column 306, causing the transmission column 306 to slide into the transmission cavity 1023. During the sliding process of the transmission column 306, the transmission column 306 rotates the transmission sleeve 307 through the transmission groove 3071 and the transmission block 3061. The transmission sleeve 307 rotates the drive sleeve 304 through the bevel gear set. The rotation of the drive sleeve 304 causes the drive roller 303 to extend in the direction away from the connecting seat 102. During the extension of the drive roller 303, it drives the transmission plate 305 to squeeze the movable plate 301 through the force surface 3051, thereby causing the movable plate 301 to move closer to the corresponding connecting plate 103; the installation of the connecting seat 102 and the extrusion of the sealant are synchronized to simplify the installation steps and improve the installation efficiency.

[0030] In some embodiments, a piston 3062 is fixedly connected to one end of the transmission column 306 located in the limiting groove 1022 , and the circumference of the piston 3062 abuts against the inner wall of the limiting groove 1022 .

[0031] Specifically, a sealing strip is fixed to the circumferential side of the piston 3062 .

[0032] The limiting groove 1022 is divided into a first region and a second region by the piston 3062, and the limiting post 202 is inserted into the first region. As the transmission post 306 moves toward the transmission cavity 1023, it drives the piston 3062 from the first region to the second region. The space in the first region increases, but the total amount of air in the first region remains unchanged. This makes the air pressure in the first region lower than the air pressure in the mounting groove 1021. This pressure difference tightens the limiting post 202, enhancing the connection stability between the connecting base 102 and the structural frame 50.

[0033] In some embodiments, see Figure 2 An auxiliary groove 1011 is provided on the back of the outer plate 101, and a reinforcement hole 1012 is provided on the inner wall of the auxiliary groove 1011; the end of the driving roller 303 is fixedly connected to an auxiliary seat 40 that is plugged into and adapted to the auxiliary groove 1011, and the auxiliary seat 40 is provided with a receiving groove 401, and a reinforcement column 402 is provided in the receiving groove 401. The reinforcement column 402 is slidingly connected to the auxiliary seat 40, and a pressure surface 4021 is provided on the side of the reinforcement column 402 away from the auxiliary seat 40, and the reinforcement column 402 is also plugged into and adapted to the reinforcement hole 1012. A deformable part 403 is fixed between the reinforcing column 402 and the auxiliary seat 40, and the deformable part 403 has a pre-tightening force that allows the reinforcing column 402 to be inserted into the reinforcement hole 1012. The deformable part 403 can be a spring or a spring rod.

[0034] When the driving roller 303 is extended, it drives the auxiliary seat 40 to be inserted into the auxiliary groove 1011. During the process of the auxiliary seat 40 being inserted into the auxiliary groove 1011, the pressure surface 4021 of the reinforcing column 402 is squeezed by the external force plate and retracted into the receiving groove 401 until the auxiliary seat 40 is completely inserted into the auxiliary groove 1011. At this time, the receiving groove 401 and the reinforcing hole 1012 are aligned, and the deformable part 403 releases the elastic force to insert the reinforcing column 402 into the reinforcing hole 1012, thereby enhancing the connection strength between the connecting seat 102 and the outer plate 101, thereby improving the stability of the plate unit 10.

[0035] In some embodiments, see Figure 2 The connecting seat 102 is provided with a through hole 1024 for the driving roller 303 to pass through, and a guide block 1025 is fixedly connected to the inner wall of the through hole 1024. The outer wall of the driving roller 303 is provided with a guide groove 3031 that is slidably adapted to the guide block 1025, and the guide groove 3031 extends axially along the driving roller 303.

[0036] During the extension of the driving roller 303 , the guide block 1025 moves along the guide groove 3031 , thereby guiding and limiting the driving roller 303 , so that the driving roller 303 can only be extended horizontally.

[0037] In some embodiments, see Figure 1 and Figure 4 The plate unit 10 also includes a surrounding plate 104 and a plurality of baffles 105; the surrounding plate 104 corresponds one-to-one to the pouring holes 1031, the surrounding plate 104 is fixedly connected to the connecting plate 103, and a plurality of first overflow holes 1041 are opened through the side wall of the surrounding plate 104; the baffles 105 correspond one-to-one to the edges of the connecting plate 103, and the baffles 105 are fixedly connected to the connecting plate 103.

[0038] After the wrapping film is squeezed and ruptured, the sealant will flow into the enclosure 104 and then flow into between the two connecting plates 103 through the first overflow hole 1041, thereby enhancing the uniformity of the sealant and ensuring waterproof performance.

[0039] In some embodiments, see Figure 4 A second overflow hole 1042 is formed on the end surface of the enclosing plate 104 facing away from the connecting plate 103 , and the second overflow hole 1042 is communicated with the first overflow hole 1041 .

[0040] The sealant in the first overflow hole 1041 will be divided into two streams, one of which flows to the outside of the enclosure 104, and the other flows between the two aligned enclosures 104, thereby sealing the two aligned enclosures 104 and further enhancing the waterproof performance.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
