Description
Technical Field
[0001] This application relates to the technical field of curtain wall construction, and in particular to a curtain wall embedded part suitable for prefabricated sandwich insulated exterior walls. Background Technology
[0002] With the development of prefabricated buildings, prefabricated sandwich insulated exterior wall panels, which are composed of inner wall panels, insulation boards and outer wall panels, have been widely used because they integrate load-bearing, enclosure and insulation functions.
[0003] Currently, to meet the needs of building facade decoration, curtain walls are usually installed on the exterior walls. Curtain walls are typically fixed to the wall structure using embedded parts. The traditional construction method involves drilling holes in the outer wall and insulation board, then fixing the embedded parts to the inner wall using expansion bolts. However, this post-construction method damages the integrity of the wall, affects the insulation effect, and results in low connection strength.
[0004] To address the aforementioned issues, related technologies integrate embedded parts with the wall structure during the production of prefabricated sandwich insulated exterior wall panels. These embedded parts include connectors and connecting plates. The connectors are fixedly connected to the connecting plates, and the connectors are fixed to the inner wall of the prefabricated sandwich insulated exterior wall panel. The connecting plates protrude from the outer wall surface of the outer wall panel for installing keel corner brackets.
[0005] However, in the above scheme, the embedded parts of the curtain wall are usually fixed in position after the wall is prefabricated. When the spacing requirements between the curtain wall and the wall surface are different in different projects, it is necessary to replace the keel corner brackets of different specifications to adapt them, which has poor versatility. Summary of the Invention
[0006] To improve the versatility of curtain wall embedded parts used in prefabricated sandwich insulated exterior walls, this application provides a curtain wall embedded part suitable for prefabricated sandwich insulated exterior walls.
[0007] This application provides a curtain wall embedded component suitable for prefabricated sandwich insulated exterior walls, employing the following technical solution:
[0008] A curtain wall embedded component suitable for prefabricated sandwich insulated exterior walls, comprising a connector, a connecting plate, and a length adjustment assembly; The connector is used to connect to the inner wall of the prefabricated sandwich insulated exterior wall; The length adjustment assembly includes an outer tube, an inner tube, and a length locking component; one end of the outer tube is connected to the connecting component, and the other end passes through the insulation board and outer wall of the prefabricated sandwich insulated exterior wall, extending to the outside of the outer wall; the inner tube is slidably connected to the outer tube, and the connecting plate is connected to the end of the inner tube away from the outer tube; the length locking component is used to lock the relative position of the inner tube and the outer tube; the connecting plate is used to install the curtain wall keel.
[0009] By adopting the above technical solution, when it is necessary to adjust the distance between the curtain wall and the outer wall surface, the inner tube slides relative to the outer tube, and then the relative position of the inner tube and the outer tube is fixed by the length locking component, thereby realizing the adjustment of the distance between the curtain wall and the outer wall surface and improving the versatility of the embedded parts.
[0010] Optionally, the connector includes a first embedded plate, a second embedded plate, and a plurality of fixing plates; The first embedded plate and the second embedded plate are connected by a plurality of the fixing plates. Both the first embedded plate and the second embedded plate are connected to the inner wall of the prefabricated sandwich insulated exterior wall. The outer pipe is connected to the first embedded plate.
[0011] By adopting the above technical solution, the first embedded plate and the second embedded plate are connected by multiple fixing plates to form an integral load-bearing structure, which increases the anchoring strength between the connector and the inner wall, thereby improving the load-bearing capacity and stability of the connection between the connector and the inner wall.
[0012] Optionally, it also includes an angle adjustment component, through which the inner tube is connected to the connecting plate, and the angle adjustment component is used to adjust the angle of the connecting plate.
[0013] By adopting the above technical solution, the angle adjustment component can adjust the angle of the connecting plate relative to the prefabricated sandwich insulated exterior wall, so that the connecting plate is kept at the required installation angle, reducing the possibility of difficulties in curtain wall keel installation or substandard flatness due to errors caused by the installation and production of prefabricated sandwich insulated exterior walls.
[0014] Optionally, the angle adjustment assembly includes a ball head and a clamping member; The ball head is rotatably connected to the inner tube, and the ball head is connected to the connecting plate; The clamping member is disposed on the inner tube and is used to clamp the ball head to restrict the rotation of the ball head.
[0015] By adopting the above technical solution, the ball head is rotatably connected to the inner tube, allowing the connecting plate to rotate relative to the inner tube in multiple directions, thereby achieving angle adjustment of the connecting plate. After the angle of the connecting plate is adjusted, the ball head is clamped by the clamping component, fixing the position of the ball head and reducing the possibility of the connecting plate moving during operation.
[0016] Optionally, the clamping member includes two clamping seats and a drive rod; the drive rod is rotatably connected to the inner tube, and the clamping seats are slidably connected to the inner tube; the drive rod is provided with two threads with opposite directions, and the two clamping seats are respectively threadedly connected to the two threads of the drive rod. The drive rod rotates, causing the two clamping seats to move closer or further apart along the drive rod to clamp or release the ball head.
[0017] By adopting the above technical solution, the rotating drive rod can drive the two clamping seats to move closer or further apart, thereby clamping or releasing the ball head, and thus switching between the angle adjustment and locking states of the connecting plate.
[0018] Optionally, the angle adjustment assembly further includes a limiting member disposed on the inner tube, the limiting member being used to limit the movement of the clamping seat.
[0019] By adopting the above technical solution, the limiting component limits the movement of the clamping seat, reducing the possibility of the clamping seat loosening due to external force after clamping the ball head, and improving the stability and reliability of the locking state of the angle adjustment component.
[0020] Optionally, the limiting component includes a limiting rod, a limiting seat, and a limiting block; One end of the limiting rod is connected to the clamping seat, and the other end passes through the inner tube; the limiting seat is connected to the inner tube, and the limiting block is slidably connected to the limiting seat; When the two clamping seats clamp the ball head, the limiting block abuts against the end face of the limiting rod to restrict the movement of the limiting rod.
[0021] By adopting the above technical solution, after the clamping seat locks the ball head, the limiting block moves to abut against the end face of the limiting rod, thereby restricting the movement of the clamping seat connected to it and reducing the possibility of the ball head loosening due to the movement of the clamping seat.
[0022] Optionally, a slider is connected to the limiting block, and a groove is provided on the limiting seat, with the slider slidably connected to the groove.
[0023] By adopting the above technical solution, the slider and the slide groove slide together, providing guidance for the movement of the limit block relative to the limit seat, reducing the possibility of the limit block deviating when it moves.
[0024] Optionally, the limiting seat and the limiting block are respectively provided with positioning holes, which are used to install screws to fix the position of the limiting block.
[0025] By adopting the above technical solution, when the limiting block moves to abut against the end face of the limiting rod, the positioning hole on the limiting block aligns with the positioning hole on the limiting seat, thereby facilitating the installation of screws and fixing the position of the limiting block.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. When it is necessary to adjust the distance between the curtain wall and the exterior wall, the inner tube slides relative to the outer tube, and then the relative position of the inner tube and the outer tube is fixed by the length locking component, thereby realizing the adjustment of the distance between the curtain wall and the exterior wall and improving the versatility of the embedded parts;
[0028] 2. The first and second embedded plates are connected by multiple fixing plates to form an integral load-bearing structure, which increases the anchoring strength between the connector and the inner wall, thereby improving the load-bearing capacity and stability of the connection between the connector and the inner wall;

[0040] The following combination Figures 1-9 This application will be described in further detail.
[0041] This application discloses an embedded component for curtain walls suitable for prefabricated sandwich insulated exterior walls. For example... Figure 1 and Figure 2 As shown, the curtain wall embedded parts include connector 1, connecting plate 2, length adjustment component 3 and angle adjustment component 4.
[0042] Specifically, such as Figure 1 and Figure 2 As shown, the connector 1 includes a first embedded plate 11, a second embedded plate 12, and multiple fixing plates 13. The first embedded plate 11 and the second embedded plate 12 are fixedly connected by two fixing plates 13. In this embodiment, the connector 1 is pre-embedded in the inner wall 71 during the production of the prefabricated sandwich insulated exterior wall 7 and welded to the reinforcing steel bars in the inner wall 71, thereby achieving a stable connection between the connector 1 and the inner wall 71, thus improving the load-bearing capacity of the curtain wall embedded parts.
[0043] like Figure 2 and Figure 3 As shown, the length adjustment assembly 3 includes an outer tube 31, an inner tube 32, and a length locking component 33. One end of the outer tube 31 is fixedly connected to the first embedded plate 11, and the other end passes through the insulation board 73 and the outer wall 72 of the prefabricated sandwich insulated outer wall 7, extending to the outside of the outer wall 72. The inner tube 32 is fitted inside the outer tube 31 and is slidably connected to the outer tube 31, so that the inner tube 32 can slide relative to the outer tube 31 along the axial direction of the outer tube 31, thereby adjusting the length of the inner tube 32 extending out of the outer tube 31.
[0044] Furthermore, such as Figure 2 and Figure 3As shown, the inner tube 32 has multiple adjusting holes 321 spaced apart along its length, and the outer tube 31 has locking holes 311 corresponding to the adjusting holes 321. In this embodiment, the length locking member 33 is a bolt. When the adjusting holes 321 and the locking holes 311 are aligned, the length locking member 33 passes through the locking holes 311 and the adjusting holes 321 in sequence, locking the relative position of the inner tube 32 and the outer tube 31. When adjusting the distance between the curtain wall and the outer wall surface, first loosen the length locking member 33, slide the inner tube 32 to the desired position, align the adjusting holes 321 on the inner tube 32 with the corresponding locking holes 311 on the outer tube 31, and then pass the length locking member 33 through the locking holes 311 and the adjusting holes 321, thereby fixing the relative position of the inner tube 32 and the outer tube 31, realizing the adjustment of the distance between the curtain wall and the outer wall surface, and improving the versatility of the embedded parts.
[0045] like Figure 4 , Figure 5 and Figure 6 As shown, the angle adjustment assembly 4 includes a ball head 41 and a clamping member 42. A ball socket 322 is provided at the end of the inner tube 32 furthest from the outer tube 31. The ball head 41 is fixedly connected to the connecting plate 2 and rotatably mounted within the ball socket 322. The ball socket 322 has an arc surface adapted to the ball head 41. When adjusting the angle of the connecting plate 2, the connecting plate 2 rotates within the ball socket 322 via the ball head 41, thereby allowing the connecting plate 2 to rotate relative to the inner tube 32 in multiple directions, thus adjusting the angle of the connecting plate 2. By using the angle adjustment assembly 4 to adjust the angle of the connecting plate 2, the possibility of the curtain wall keel 6 shifting due to errors in the production or installation of the prefabricated sandwich insulated exterior wall 7, causing the connecting plate 2 to shift, is reduced.
[0046] Meanwhile, the connecting plate 2 has multiple mounting holes 21, which are elongated holes, to facilitate the installation of the keel angle bracket 5 onto the connecting plate 2 using bolts. In addition, the angle adjustment component 4, combined with the elongated holes on the keel angle bracket 5 for installing the curtain wall keel 6, improves the flexibility of the position adjustment of the curtain wall keel 6 and enhances the flatness of the installation between adjacent curtain wall keels 6.
[0047] like Figure 5 and Figure 7 As shown, the clamping member 42 includes two clamping seats 421 and a drive rod 422. The clamping seats 421 are slidably connected to the inner tube 32, and the side of the clamping seat 421 facing the ball head 41 is provided with an arc-shaped clamping surface adapted to the ball head 41. The drive rod 422 is rotatably connected to the inner tube 32, and the drive rod 422 is provided with two threads with opposite directions. The two clamping seats 421 are respectively threadedly connected to the two threads of the drive rod 422, so that when the drive rod 422 is rotated, the two clamping seats 421 can move closer to each other or further away from each other along the drive rod 422.
[0048] When the two clamping seats 421 are close to each other, they clamp the ball head 41 from both sides, thereby restricting the rotation of the ball head 41 and fixing the angle of the connecting plate 2. When the two clamping seats 421 are far apart, they release the ball head 41, and the ball head 41 can rotate in the ball socket 322, which facilitates the readjustment of the angle of the connecting plate 2.
[0049] like Figure 8 and Figure 9 As shown, the angle adjustment assembly 4 also includes a limiting member 43, which includes a limiting rod 431, a limiting seat 432, and a limiting block 433. One end of the limiting rod 431 is fixedly connected to the clamping seat 421, and the other end passes through the side wall of the inner tube 32 and extends to the outside of the inner tube 32. A clearance hole is provided on the side wall of the inner tube 32 for the limiting rod 431 to pass through. The limiting seat 432 is fixedly connected to the inner tube 32 and has a sliding groove 4321. A slider 4331 is connected to the limiting block 433, and the slider 4331 is slidably connected to the sliding groove 4321, allowing the limiting block 433 to slidably connect to the limiting seat 432.
[0050] After the two clamping seats 421 clamp the ball head 41, the sliding limiting block 433 abuts against the end face of the limiting rod 431, thereby restricting the movement of the limiting rod 431 away from the ball head 41, and thus restricting the movement of the clamping seats 421 connected to the limiting rod 431. Since both clamping seats 421 are threadedly connected to the drive rod 422, restricting the movement of one clamping seat 421 can restrict the rotation of the drive rod 422, thereby keeping both clamping seats 421 in a state of clamping the ball head 41, reducing the possibility that the clamping seats 421 may loosen the ball head 41 due to external force or long-term vibration.
[0051] like Figure 9 As shown, positioning holes 434 are respectively provided on the limiting seat 432 and the limiting block 433. After the limiting block 433 moves to abut against the end face of the limiting rod 431, the positioning holes 434 on the limiting seat 432 are aligned with the positioning holes 434 on the limiting block 433. At this time, by passing screws through the positioning holes 434 on the limiting seat 432 and the limiting block 433, the limiting block 433 and the limiting seat 432 are relatively fixed, reducing the possibility of the limiting block 433 moving and further improving the stability and reliability of the locking state of the angle adjustment component 4.
[0052] The implementation principle of an embedded component for a precast sandwich insulated exterior wall 7 according to an embodiment of this application is as follows:
[0053] During the production of the prefabricated sandwich insulated exterior wall 7, the connector 1 is pre-embedded in the inner wall 71, and the outer pipe 31 extends to the outside of the outer wall 72 after passing through the insulation board 73 and the outer wall 72.
[0054] When installing the curtain wall, first slide the inner tube 32 to the required position according to the distance requirement between the curtain wall and the outer wall surface, and lock the relative position of the inner tube 32 and the outer tube 31 through the length locking piece 33 to complete the adjustment of the distance between the curtain wall and the outer wall surface.
[0055] Then, according to the installation angle requirements of the curtain wall keel 6, the connecting plate 2 is rotated to drive the ball head 41 to rotate to the required angle in the ball socket 322, and then the drive rod 422 is rotated to bring the two clamping seats 421 closer to each other to clamp the ball head 41, thus fixing the angle of the connecting plate 2.
[0056] Subsequently, the sliding limit block 433 is brought into contact with the end face of the limit rod 431, and the limit block 433 is locked by screws.
[0057] Finally, the curtain wall keel 6 is installed on the connecting plate 2 via the keel corner bracket 5.
[0058] 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.
