Description

Technical Field

[0001] This invention relates to the field of steel frame keel connection and installation technology, and in particular to a method for connecting steel frame keels in aluminum panel curtain walls. Background Technology

[0002] Currently, aluminum panel curtain wall structures have comprehensive advantages such as light weight, easy installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in terms of "high, large, and light". Therefore, they are widely used in high-rise buildings, large public buildings and other building fields. The steel frame keel is an important component of the entire aluminum panel curtain wall structure.

[0003] A search revealed Chinese patent application CN202120341769.5, which discloses a connection structure for steel frame keel in building curtain wall engineering. The structure includes a connecting seat with first positioning holes at both ends for keel insertion. Each of the first positioning holes contains a locking structure. However, this technical solution can only connect two relatively vertical and parallel steel frame keels. Existing aluminum panel curtain walls often use steel frame keels to splice multiple aluminum panel curtain walls of different shapes into polygons for aesthetic and visual effects. Therefore, two connected steel frame keels need to face different angles, making it impossible to guarantee that each connected steel frame keel is at a vertical and horizontal angle. Thus, the existing connection structure can only stably connect relatively vertical and parallel steel frame keels, and cannot effectively fix two steel frame keels at different tilt angles. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a method for connecting steel frame keels in aluminum panel curtain walls.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for connecting steel frame keel in aluminum panel curtain walls includes the following steps:

[0007] S1: Install the keel fixing structure onto the corresponding steel frame structure with bolts according to the corresponding shape;

[0008] S2: Insert the keel connecting structure into the keel fixing structure, and then install the steel frame keel on the keel connecting structure with bolts;

[0009] S3: Rotate the keel connecting structure under the guidance of the keel fixing structure to adjust the angle of the steel frame keel fixed on the keel connecting structure;

[0010] S4: After adjusting the angle of the steel frame keel, the staff pushes the keel connecting structure as a whole into the keel fixing structure, and uses the self-locking mechanism on the keel fixing structure to initially limit the keel connecting structure;

[0011] S5: The staff can release the limit on the keel connection structure through the unlocking mechanism on one side of the self-locking mechanism, and then rotate the keel connection structure to make fine adjustments to the steel frame keel before installation and fixing;

[0012] S6: After adjusting the orientation angle of the steel frame keel, fix the keel connecting structure to the keel fixing structure with bolts to complete the fixed installation of the steel frame keel.

[0013] Preferably, in S1, the keel fixing structure includes a fixing plate and a fixing sleeve. The fixing sleeve is fixed to the top outer wall of the fixing plate, and a support plate is fixed to the outer wall of the fixing sleeve.

[0014] Furthermore: In S2, the keel connection structure consists of a mounting plate, a connecting piece, a limiting sleeve, a connecting plate, a fixing piece, a pressure rod, and a slot. The limiting sleeve is inserted into the outer wall of the fixing sleeve, the connecting plate is set on the bottom outer wall of the limiting sleeve, the mounting plate is fixed on the top outer wall of the limiting sleeve, the connecting piece is set on the top outer wall of the mounting plate, the pressure rod is fixed on the bottom outer wall of the mounting plate, the slot is set on the bottom outer wall of the connecting plate, and a set of handles is provided on the bottom outer wall of the mounting plate.

[0015] In a further preferred embodiment, in S4, the self-locking mechanism comprises a pressure plate, a first elastic airbag, a connecting seat, an air guide tube, a second elastic airbag, a movable plate, a limiting frame, a locking block, and a second push plate. The first elastic airbag is disposed on the top outer wall of the fixed plate, the pressure plate is disposed on the top outer wall of the first elastic airbag, the connecting seat is disposed on one side outer wall of the first elastic airbag, the air guide tube is disposed on one side outer wall of the connecting seat, the second elastic airbag is disposed on one side outer wall of the air guide tube, the second push plate is disposed on one side outer wall of the second elastic airbag, the movable plate is disposed on one side outer wall of the second push plate, the locking block is disposed on the top outer wall of the movable plate, the limiting frame is disposed on one side outer wall of the fixed sleeve, and the movable plate is slidably connected to the inner wall of the limiting frame.

[0016] As a preferred embodiment of the present invention: the unlocking mechanism comprises a guide rod, a first push plate, a guide frame, a pad, a limiting block, and a guide block. The guide rod and the guide block are respectively disposed on the outer walls of both sides of the second push plate. The guide block is slidably connected to the inner wall of the limiting frame. The guide frame is disposed on the top outer wall of the fixed plate. The guide rod is slidably connected to the inner wall of the guide frame. The limiting block is disposed on one outer wall of the guide frame. The first push plate is disposed on one outer wall of the guide rod. The pad is disposed on one outer wall of the guide frame.

[0017] As a further preferred embodiment of the present invention: a buffer plate is provided on one side of the movable plate and the card block, a guide plate is provided on the bottom outer wall of the pressure plate, a fixing ring is provided on the bottom outer wall of the first elastic airbag, and a set of L-shaped plates is provided on the outer wall of the pressure plate, the L-shaped plates being slidably connected to the inner wall of the fixing sleeve.

[0018] As a further embodiment of the present invention: a limiting ring is fixed to the inner wall of the fixed sleeve, a rotating shaft is rotatably connected to the inner wall of the limiting frame, a set of elastic retaining strips is provided on the outer wall of the rotating shaft, and an aluminum alloy plate is provided on the outer wall of the rotating shaft.

[0019] Based on the aforementioned scheme: a magnetic sheet is provided on one side of the outer wall of the second push plate, and a set of metal blocks is provided on the top outer wall of the fixing plate.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. Workers can adjust the orientation angle of the steel frame keel fixed on the keel connection structure by rotating it. After adjustment, the steel frame keel can be initially positioned by the self-locking mechanism on the keel connection structure, which facilitates the subsequent installation of the steel frame keel. If workers find that some connected steel frame keels need to be fine-tuned during the installation process, the unlocking mechanism on one side of the self-locking mechanism can be used to release the limit on the steel frame keel, so that the connected steel frame keel can be fine-tuned at any time. This facilitates the installation of aluminum panel curtain walls of different shapes. After the workers have adjusted the angle and position of all steel frame keels, the keel connection structure can be stably fixed to the keel fixing structure with bolts, so as to effectively install and fix the steel frame keels with different orientation angles.

[0022] 2. Fix the steel frame keel to be connected to the connecting plate with bolts. Under the guidance of the fixing sleeve and the pressure rod, rotate the mounting plate to adjust the angle of the steel frame keel. After adjusting the angle, the worker continues to push the mounting plate downward with force through the handle, so that the pressure rod at the bottom of the mounting plate squeezes the self-locking mechanism. When the connecting plate at the bottom of the limiting sleeve moves down to the top outer wall of the support plate with the mounting plate, the self-locking mechanism will also complete the initial limiting of the limiting sleeve and the mounting plate as a whole through the slot at the bottom of the connecting plate, preventing the steel frame keel connected to the mounting plate from rotating easily.

[0023] 3. When the operator pushes the mounting plate into the fixed sleeve, the pressure rod at the bottom of the mounting plate will squeeze the pressure plate. After the first elastic airbag is squeezed, it will fill the second elastic airbag with gas through the air guide tube. After the second elastic airbag expands, it will push the second push plate forward, pushing the entire movable plate forward at a uniform speed under the guidance of the limit frame. This allows the locking block at the top of the movable plate to move out of the fixed sleeve along with the movable plate. When the bottom outer wall of the connecting plate descends to the top outer wall of the support plate, the corresponding slot at the bottom of the connecting plate will also lock onto the locking block protruding from the fixed sleeve, thus limiting the rotatable connection between the limit sleeve and the entire mounting plate at the top of the fixed sleeve.

[0024] 4. When the operator needs to move the limiting sleeve upwards and then rotate the mounting plate to fine-tune the orientation angle of the steel frame keel, the first push plate pushes the guide rod and the second push plate forward as a whole. This causes the second push plate to compress the expanded second elastic airbag, refilling the first elastic airbag with gas. This allows the expanded first elastic airbag to push the limiting sleeve and the mounting plate upwards as a whole, thus releasing the locking block and slot from limiting the mounting plate and the limiting sleeve. At this point, the operator can fine-tune the angle of the steel frame keel by rotating the mounting plate.

[0025] 5. When the movable plate moves forward, it will lift the aluminum alloy plate at the bottom of the rotating shaft upward, so that a set of elastic clips on one side of the rotating shaft will flip up onto the fixing piece of the connecting plate on the outer wall of the clip block. This will work with the clip block to fix and limit the mounting plate and the limiting sleeve inserted on one side of the fixed sleeve, preventing the mounting plate and the limiting sleeve from easily falling off the fixed sleeve. This will make it easier for the staff to fix the multiple fixing pieces against the side of the support plate with bolts. Attached Figure Description

[0041] Example 1:

[0042] A method for connecting steel frame keels in aluminum panel curtain walls, such as... Figure 1-7 As shown, it includes the following steps:

[0043] S1: Install the keel fixing structure onto the corresponding steel frame structure with bolts according to the corresponding shape;

[0044] S2: Insert the keel connecting structure into the keel fixing structure, and then install the steel frame keel on the keel connecting structure with bolts;

[0045] S3: Rotate the keel connecting structure under the guidance of the keel fixing structure to adjust the angle of the steel frame keel fixed on the keel connecting structure;

[0046] S4: After adjusting the angle of the steel frame keel, the staff pushes the keel connecting structure as a whole into the keel fixing structure, and uses the self-locking mechanism on the keel fixing structure to initially limit the keel connecting structure;

[0047] S5: The staff can release the limit on the keel connection structure through the unlocking mechanism on one side of the self-locking mechanism, and then rotate the keel connection structure to make fine adjustments to the steel frame keel before installation and fixing;

[0048] S6: After adjusting the orientation angle of the steel frame keel, fix the keel connecting structure to the keel fixing structure with bolts to complete the fixed installation of the steel frame keel.

[0049] Workers can adjust the orientation angle of the steel frame keel fixed on the keel connection structure by rotating it. After adjustment, the steel frame keel can be initially positioned by the self-locking mechanism on the keel connection structure, facilitating the subsequent installation of the steel frame keel. If workers find that some connected steel frame keels need to be fine-tuned during installation, they can release the limit on the steel frame keel by using the unlocking mechanism on one side of the self-locking mechanism, thus allowing for fine-tuning of the connected steel frame keel at any time. This facilitates the installation of aluminum panel curtain walls of different shapes. After the workers have adjusted the angle and position of all steel frame keels, the keel connection structure can be stably fixed to the keel fixing structure with bolts, thereby effectively installing and fixing steel frame keels with different orientation angles.

[0050] like Figure 1-7 As shown, in S1, the keel fixing structure includes a fixing plate 1 and a fixing sleeve 13. The fixing sleeve 13 is fixed to the top outer wall of the fixing plate 1, and a support plate 10 is fixed to the outer wall of the fixing sleeve 13. The workers fix the fixing plate 1 to the steel frame structure used to support the aluminum panel curtain wall by bolts.

[0051] like Figure 1-7 As shown, in S2, the keel connection structure consists of a mounting plate 4, a connecting piece 6, a limiting sleeve 5, a connecting plate 2, a fixing piece 20, a pressure rod 26, and a slot 21. The limiting sleeve 5 is inserted into the outer wall of the fixing sleeve 13. The connecting plate 2 is disposed on the bottom outer wall of the limiting sleeve 5. The mounting plate 4 is fixed to the top outer wall of the limiting sleeve 5. The connecting piece 6 is disposed on the top outer wall of the mounting plate 4. The pressure rod 26 is fixed to the bottom outer wall of the mounting plate 4. The slot 21 is disposed on the bottom outer wall of the connecting plate 2. A set of handles 3 is provided on the bottom outer wall of the mounting plate 4. The operator first lifts the mounting plate 4 as a whole using the handles 3, and then inserts the limiting sleeve 5 and the pressure rod 26 at the bottom of the mounting plate 4 into the fixing sleeve 13 respectively. On the outer and inner walls, the mounting plate 4 is initially positioned. Then, the steel frame keel to be connected is fixed to the connecting piece 6 with bolts. Then, under the guidance of the fixing sleeve 13 and the pressure rod 26, the mounting plate 4 is rotated to adjust the angle of the steel frame keel. After the angle is adjusted, the worker continues to push the mounting plate 4 downward with force through the handle 3, so that the pressure rod 26 at the bottom of the mounting plate 4 squeezes the self-locking mechanism. When the connecting plate 2 at the bottom of the limiting sleeve 5 moves downward with the mounting plate 4 to the top outer wall of the support plate 10, the self-locking mechanism will also complete the initial limiting of the limiting sleeve 5 and the mounting plate 4 as a whole through the slot 21 at the bottom of the connecting plate 2, so as to prevent the steel frame keel connected to the mounting plate 4 from rotating easily.

[0052] like Figure 1-7As shown, in S4, the self-locking mechanism consists of a pressure plate 16, a first elastic airbag 15, a connecting seat 35, an air guide tube 34, a second elastic airbag 27, a movable plate 19, a limiting frame 32, a locking block 29, and a second push plate 23. The first elastic airbag 15 is disposed on the top outer wall of the fixed plate 1, the pressure plate 16 is disposed on the top outer wall of the first elastic airbag 15, the connecting seat 35 is disposed on one side outer wall of the first elastic airbag 15, the air guide tube 34 is disposed on one side outer wall of the connecting seat 35, the second elastic airbag 27 is disposed on one side outer wall of the air guide tube 34, the second push plate 23 is disposed on one side outer wall of the second elastic airbag 27, the movable plate 19 is disposed on one side outer wall of the second push plate 23, the locking block 29 is disposed on the top outer wall of the movable plate 19, the limiting frame 32 is disposed on one side outer wall of the fixed sleeve 13, and the movable plate 19 is slidably connected to the limiting frame 33. On the inner wall of 2; when the worker pushes the mounting plate 4 into the fixed sleeve 13, the pressure rod 26 at the bottom of the mounting plate 4 will squeeze the pressure plate 16, thereby squeezing the first elastic airbag 15 at the bottom through the pressure plate 16. After the first elastic airbag 15 is squeezed, it will fill the second elastic airbag 27 through the air guide pipe 34. After the second elastic airbag 27 expands, it will push the second push plate 23 forward, thereby pushing the entire movable plate 19 forward at a uniform speed under the guidance of the limit frame 32, so that the locking block 29 at the top of the movable plate 19 moves out of the fixed sleeve 13 along with the movable plate 19. When the bottom outer wall of the connecting plate 2 descends to the top outer wall of the support plate 10, the corresponding slot 21 at the bottom of the connecting plate 2 will also be locked on the locking block 29 protruding from the fixed sleeve 13, thus limiting the entire assembly of the limit sleeve 5 and the mounting plate 4 that are rotatably connected to the top of the fixed sleeve 13.

[0053] like Figure 1-7As shown, the unlocking mechanism consists of a guide rod 24, a first push plate 12, a guide frame 9, a pad 11, a limiting block 8, and a guide block 30. The guide rod 24 and the guide block 30 are respectively disposed on the outer walls of the two sides of the second push plate 23. The guide block 30 is slidably connected to the inner wall of the limiting frame 32. The guide frame 9 is disposed on the top outer wall of the fixed plate 1. The guide rod 24 is slidably connected to the inner wall of the guide frame 9. The limiting block 8 is disposed on one outer wall of the guide frame 9. The first push plate 12 is disposed on one outer wall of the guide rod 24. The pad 11 is disposed on one outer wall of the guide frame 9. The operator needs to move the limiting sleeve 5 upwards. When the installation plate 4 is rotated to fine-tune the orientation angle of the steel frame keel, the guide rod 24 and the second push plate 23 are first pushed forward by the first push plate 12. The second push plate 23 then compresses the expanded second elastic airbag 27, causing the gas inside the second elastic airbag 27 to be refilled into the first elastic airbag 15. This allows the expanded first elastic airbag 15 to push the limiting sleeve 5 and the installation plate 4 upward, thereby releasing the limiting of the installation plate 4 and the limiting sleeve 5 by the locking block 29 and the locking groove 21. At this point, the operator can fine-tune the angle of the steel frame keel by rotating the installation plate 4.

[0054] like Figure 1-7 As shown, a buffer plate 28 is provided on one side of the outer wall of the movable plate 19 and the locking block 29, a guide plate 14 is provided on the bottom outer wall of the pressure plate 16, a fixing ring 25 is provided on the bottom outer wall of the first elastic airbag 15, and a set of L-shaped plates 17 are provided on the outer wall of the pressure plate 16. The L-shaped plates 17 are slidably connected to the inner wall of the fixing sleeve 13. The buffer plate 28 and the guide plate 14 can guide, support and limit the first elastic airbag 15 when it expands and contracts, thereby improving the stability of the first elastic airbag 15 when it expands and contracts. The L-shaped plates 17 can guide and limit the pressure plate 16 when it slides back and forth on the inner wall of the fixing sleeve 13. The fixing ring 25 can limit and fix the first elastic airbag 15 located on the top of the fixing plate 1.

[0055] like Figure 1-7As shown, a limiting ring 18 is fixed to the inner wall of the fixed sleeve 13, and a rotating shaft 36 is rotatably connected to the inner wall of the limiting frame 32. A set of elastic clips 37 are provided on the outer wall of the rotating shaft 36, and an aluminum alloy plate 33 is provided on the outer wall of the rotating shaft 36. The limiting ring 18 can block and limit the descending pressure plate 16. When the movable plate 19 pushes the locking block 29 forward under the push of the second elastic airbag 27 and moves it out of the fixed sleeve 13, the movable plate 19 will lift the aluminum alloy plate 33 at the bottom of the rotating shaft 36 upward when it moves forward, so that a set of elastic clips 37 on one side of the rotating shaft 36 will flip upward and be locked onto the fixing piece 20 of the connecting plate 2 on the outer wall of the locking block 29. This will cooperate with the locking block 29 to fix and limit the mounting plate 4 and the limiting sleeve 5 inserted on one side of the fixed sleeve 13 as a whole, preventing the mounting plate 4 and the limiting sleeve 5 from easily falling off the fixed sleeve 13, and making it convenient for the staff to fix the multiple fixing pieces 20 against one side of the support plate 10 with bolts.

[0056] Example 2:

[0057] A method for connecting steel frame keels in aluminum panel curtain walls, such as... Figure 1-7 As shown, this embodiment makes the following improvements based on embodiment 1: A magnetic piece 22 is provided on one side of the outer wall of the second push plate 23, and a set of metal blocks 7 is provided on the top outer wall of the fixing plate 1; the magnetic piece 22 can be attracted to the metal blocks 7 by its own magnetic force, thereby fixing and limiting the expanded second elastic airbag 27, so that the gas on the inner wall of the second elastic airbag 27 will not easily fill the first elastic airbag 15, so that the connecting plate 2 can be stably pressed against the support plate 10. When the second push plate 23 leaves the side of the metal block 7 under the force of the guide rod 24 pushed by the worker, the aluminum alloy plate 33 will flip down by its own gravity, thereby covering one side of the second push plate 23 and blocking the magnetic piece 22 on one side of the second push plate 23, so as to prevent the magnetic piece 22 from continuing to emit magnetic force when it is retracted into the limiting frame 32, affecting the installation and debugging of other steel frame keels.

[0058] In this embodiment, the magnet 22 can be attracted to the metal block 7 by its own magnetic force, thereby fixing and limiting the expanded second elastic airbag 27, so that the gas inside the second elastic airbag 27 will not easily fill the first elastic airbag 15, so that the connecting plate 2 can be stably pressed against the support plate 10.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
