Description

Technical Field

[0001] This application relates to the field of building curtain wall construction equipment technology, and in particular to a double-track cantilever support structure for irregular curved curtain walls. Background Technology

[0002] A curtain wall is a decorative structure installed on the exterior of a building. The curtain wall itself is not a major load-bearing structure of the building. After the curtain wall construction is completed, it appears as a curtain hanging on the outside of the building, hence the name "curtain wall". According to the material of the curtain wall, it can be divided into glass curtain walls, metal curtain walls, stone curtain walls, ceramic curtain walls, etc.

[0003] In the actual construction of curtain walls, since the curtain wall is assembled from multiple unit panels, operators need to install each unit panel one by one on the exterior facade of the building to ultimately form the overall curtain wall structure. For some high-rise buildings, cranes and hoisting machines are often insufficient to meet the installation height requirements of the unit panels. In such cases, operators need to pre-install a support structure at the top of the high-rise building. With the help of this support structure and hoisting equipment, the unit panels are hoisted from top to bottom to the required installation position on the exterior facade of the building, making it easier for operators to install the unit panels.

[0004] However, for some uniquely styled and oddly shaped high-rise buildings, such as those that gradually narrow from bottom to top, the horizontal distance between the installation position of the unit panels and the top edge of the building also gradually increases from top to bottom. Therefore, common support structures are not suitable for providing support for the curtain wall unit panels of such buildings. Summary of the Invention

[0005] To facilitate the installation of curtain wall unit panels for buildings that gradually narrow from bottom to top, this application provides a double-track cantilever support structure for irregularly shaped curved curtain walls.

[0006] This application provides a double-track cantilever support structure for irregular curved curtain walls, employing the following technical solution:

[0007] A double-track cantilever support structure for an irregularly shaped curved curtain wall includes a support rail and a hoisting rod. A fixing device is installed on the support rail to fix it to the top of the building. An adjusting plate is installed on the hoisting rod, and a gap is provided between the adjusting plate and the hoisting rod. The support rail is slidably disposed within the gap. A connecting member is provided between the adjusting plate and the hoisting rod, and the adjusting plate and the hoisting rod are connected through the connecting member. The structure also includes a locking device for locking the support rail and the hoisting rod.

[0008] With the above technical solution, before the operators hoist the unit panels of the curtain wall downwards, they first insert the support rail into the gap between the adjusting plate and the hoisting rod, so that the hoisting rod can slide along the length of the support rail. Then, the support rail is horizontally suspended at the top of the building, so that the support rail is partially suspended, so that the hoisting rod can provide support for the unit panels (the subsequent downward hoisting is achieved by a winch or a hand-operated hoist, which will not be described in detail here), and the support rail is fixed to the top of the building by a fixing device.

[0009] For the installation of unit panels in building curtain walls that gradually narrow from bottom to top, as the horizontal distance between the required installation position of the unit panel and the top edge of the building gradually increases, the operator can gradually slide the hoisting rod away from the top edge of the building to increase the horizontal distance between the hoisting rod and the top edge of the building, thereby hoisting the unit panel to be installed to the predetermined installation position. Therefore, this structure can provide support for the installation of curtain wall unit panels in buildings that gradually narrow from bottom to top.

[0010] In a preferred embodiment, the present application may be further configured such that: the connector includes a plurality of connecting rods, one end of each connecting rod is fixedly connected to the adjusting plate, the other end of each connecting rod is mounted on the hoisting rod, the plurality of connecting rods are divided into two groups, and the two groups of connecting rods are respectively arranged on both sides of the support rail.

[0011] Through the above technical solution, the adjusting rod is installed on the hoisting rod through the connecting rod, thereby forming a gap for the support rail to slide. Furthermore, connecting rods are provided on both sides of the support rail. Therefore, under the obstruction of the connecting rods on both sides, the possibility of the hoisting rod detaching from the support rail is reduced, which also reduces the possibility of safety accidents and improves the safety of the equipment during use.

[0012] In a preferred embodiment, this application can be further configured such that: the hoisting rod is an I-beam, the bottom of the connecting rod is fixedly connected to a sliding sub-rail, the sliding sub-rail has a groove, the flange of the I-beam is slidably disposed in the groove, and the I-beam is installed on the connecting rod through the sliding sub-rail.

[0013] Through the above technical solution, since the flange of the I-beam (i.e., the lifting rod) can move along the groove of the sliding subrail, that is, the I-beam can move horizontally along the length direction perpendicular to the support rail, this increases the adjustable dimension of the I-beam. In other words, the I-beam can not only move along the length direction of the support rail, but also move in the direction perpendicular to the support rail. This makes it easier for the I-beam to provide support for the installation of adjacent unit plates at the same height, thereby reducing the number of times the operator has to move the support structure and improving work efficiency.

[0014] In a preferred embodiment, the locking device may be further configured as follows: the locking device includes a drive shaft, a fixing pin, and a lead screw, both of which are rotatably mounted inside the connecting rod. The fixing pin is slidably disposed on the connecting rod. A plurality of plug-in plates are mounted on the support rail, and the plug-in plates have plug-in holes for the fixing pin to be inserted into. The lead screw is threadedly connected to the fixing pin. A bevel gear is mounted on the drive shaft, and a bevel gear is mounted on the lead screw. The bevel gear and the bevel gear mesh with each other.

[0015] With the above technical solution, after the operator adjusts the I-beam (i.e., the hoisting rod) to a suitable position along the length of the support rail, the transmission shaft is rotated. The transmission shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the first lead screw to rotate, and the first lead screw drives the fixing pin to move towards the insertion plate, so that the fixing pin is inserted into the insertion hole. Under the obstruction of the fixing pin, the possibility of the hoisting rod moving along the length of the support rail is reduced.

[0016] In a preferred embodiment, this application can be further configured as follows: a limiting block is slidably provided at the bottom of the I-beam along the vertical direction, the limiting block and the flange of the I-beam abut against each other, a second lead screw is rotatably installed inside the sliding subrail, the second lead screw and the limiting block are threadedly connected, a guide rod is installed on the sliding subrail, and a guide hole is provided on the limiting block for the guide rod to slide.

[0017] With the above technical solution, after the operator completes the adjustment of the I-beam (i.e., the hoisting rod) along the direction perpendicular to the length of the support rail, the second lead screw is rotated. The second lead screw drives the limit block to move upward, so that the limit block presses against the wing plate at the bottom of the I-beam. Under the clamping action of the sliding subrail and the limit block, the possibility of the I-beam moving along the direction perpendicular to the length of the support rail is reduced.

[0018] In a preferred embodiment, this application may be further configured such that the second lead screw and the transmission shaft are coaxially and fixedly connected.

[0019] With the above technical solution, after the operator completes the adjustment of the I-beam (i.e., the hoisting rod) (including the adjustment perpendicular to the length of the support rail and the adjustment along the length of the support rail), the transmission shaft is rotated. Since the transmission shaft and the second lead screw are coaxially fixedly connected, on the one hand, the transmission shaft can drive the fixing pin to be inserted into the insertion hole through the first bevel gear, the second bevel gear and the first lead screw, so as to reduce the possibility of the I-beam moving along the length of the support rail.

[0020] On the other hand, the drive shaft drives the second lead screw to rotate, and the second lead screw drives the limiting block to move upward, so that the sliding subrail and the limiting block clamp the I-beam, thereby reducing the possibility of the I-beam moving along the direction perpendicular to the length of the support rail. Therefore, the movement of the I-beam in two dimensions can be limited simultaneously, thus simplifying the operation steps of this support structure.

[0021] In a preferred embodiment, this application may be further configured such that: an anti-slip plate is installed on the limiting block, and the limiting block abuts against the flange of the I-beam through the anti-slip plate.

[0022] Through the above technical solution, the protective plate can be made of hard rubber, which has a large coefficient of friction, providing sufficient friction for the I-beam, thereby further reducing the possibility of the I-beam moving along the length direction perpendicular to the support rail.

[0023] In a preferred embodiment, the present application may be further configured such that: the fixing device includes a first fixing plate, a second fixing plate, and a connecting screw, the connecting screw passing through the first fixing plate and the second fixing plate, the support rail passing between the first fixing plate and the second fixing plate, and nuts provided on the opposite sides of the first fixing plate and the second fixing plate, the nuts being threadedly engaged with the connecting screw.

[0024] With the above technical solution, after the operator places the support rail on the top of the building, the first fixing plate is placed on the top surface of the support rail, and the second fixing plate is placed at the bottom of the top beam of the building. Then, the connecting screw is passed through the first fixing plate and the second fixing plate, and finally the nuts are threaded to the top and bottom of the connecting screw respectively. Under the obstruction of the first fixing plate, the second fixing plate and the nuts, the possibility of the support rail overturning is reduced.

[0025] In a preferred embodiment, this application may be further configured such that: a limiting plate 1 and a limiting plate 2 for blocking the fixing plate 1 are installed on the support rail, and the limiting plate 1 and the limiting plate 2 are arranged along the length direction of the support rail.

[0026] Through the above technical solution, the possibility of the support rail sliding at the top of the building is reduced by the obstruction of the first and second limiting plates.

[0027] In a preferred embodiment, this application may be further configured such that: the first fixing plate has a limiting groove for the first limiting plate and the second limiting plate to pass through.

[0028] Through the above technical solution, since both the first limiting plate and the second limiting plate can be inserted into the limiting groove, the integrity of the first limiting plate, the second limiting plate and the first fixing plate is improved.

[0029] In summary, this application includes the following beneficial technical effects:

[0030] 1. By sliding the I-beam (i.e., the hoisting rod) along the length of the support rail, the operator increases the horizontal distance between the I-beam and the top edge of the building, thereby enabling the hoisted unit panel to be hoisted to the predetermined installation position. Therefore, this structure can provide support for the installation of curtain wall unit panels of buildings that gradually narrow from bottom to top.

[0031] 2. Operators slide the I-beam (i.e., the hoisting rod) along the length of the support rail to provide support for the installation of adjacent unit plates at the same height, which reduces the number of times operators need to move the support structure and improves work efficiency.

[0032] 3. By rotating the drive shaft, the operator drives the fixing pin to insert into the insertion hole, reducing the possibility of the I-beam moving along the length of the support rail. Simultaneously, it drives the limiting block to move upwards, clamping the I-beam between the sliding sub-rail and the limiting block, further reducing the possibility of the I-beam moving perpendicular to the length of the support rail. Therefore, it can simultaneously limit the movement of the I-beam in two dimensions, simplifying the operation of this support structure. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0042] This application discloses a double-track cantilever support structure for irregular curved curtain walls.

[0043] See attached document Figure 1 and attached Figure 2 As shown, a double-track cantilever support structure for an irregular curved curtain wall includes a hoisting rod 2 and two support rails 1. The two support rails 1 are arranged parallel to each other on the top of the building where the curtain wall is to be installed. Part of each support rail 1 is suspended in the air, and the remaining part of each support rail 1 is supported on the top of the building. The structure also includes a fixing device 3, which is used to fix the support rails 1 to the top of the building.

[0044] See attached document Figure 1 and attached Figure 2 As shown, since the two support rails 1 have the same structure, only the hoisting rod 2 and one of the support rails 1 will be described in detail below, and the other support rail 1 will not be described in detail.

[0045] See attached document Figure 1 Appendix Figure 2 and appendix Figure 3As shown, an adjusting plate 4 is positioned directly above the lifting rod 2, with a gap 41 between the adjusting plate 4 and the lifting rod 2 for the support rail 1 to slide. A connecting piece 5 is provided between the adjusting plate 4 and the lifting rod 2, connecting the adjusting plate 4 and the lifting rod 2. The connecting piece 5 includes four connecting rods 51, which are located at the four corners of the adjusting plate 4 and are evenly divided into two groups, with the two groups of connecting rods 51 respectively located on both sides of the support rail 1. The top of each connecting rod 51 is fixedly connected to the bottom surface of the adjusting plate 4, and the bottom of each connecting rod 51 is fixedly connected to a sliding sub-rail 7. The side walls of the two sliding sub-rails 7 in the same group that are close to each other are provided with grooves 71. The lifting rod 2 is an I-beam, and the flange 21 at the top of the I-beam is slidably disposed in the groove 71, that is, the I-beam is installed on the connecting rod 51 through the sliding sub-rail 7.

[0046] The operator first inserts the support rail 1 into the gap 41 and fixes the support rail 1 to the top of the building using the fixing device 3, so that a portion of each support rail 1 is suspended outside the top of the building. The suspended part of the support rail 1 provides support for the hoisting of the unit panel. The operator slides the I-beam along the length of the support rail 1, that is, the support rail 1 slides relative to the I-beam within the gap 41, to increase the horizontal distance between the I-beam and the edge of the top of the building, thereby enabling the unit panel to be hoisted to the predetermined installation position. This structure can provide support for the installation of curtain wall unit panels of a building that gradually narrows from bottom to top.

[0047] In addition, the operator can slide the I-beam along the length direction perpendicular to the support rail 1, that is, the flange 21 of the I-beam slides in the groove 71 of the sliding sub-rail 7, so that the I-beam can provide support for the installation of adjacent unit plates at the same height, which reduces the number of times the operator moves this support structure and improves work efficiency.

[0048] In summary, this support structure enables the lifting rod 2 to move in two dimensions: along the length of the support rail 1 and along a direction perpendicular to the length of the support rail 1, thereby effectively expanding the applicability of this support structure.

[0049] See attached document Figure 2 and attached Figure 4As shown, this structure also includes a locking device 6, which is used to lock the support rail 1 and the hoisting rod 2. The locking device 6 includes a drive shaft 61, a fixing pin 62, and a lead screw 63. The drive shaft 61 and the lead screw 63 are both rotatably installed in one of the connecting rods 51. The fixing pin 62 is slidably disposed in the connecting rod 51. Several plug-in plates 11 are fixedly connected to the support rail 1. The plug-in plates 11 are evenly distributed along the length of the support rail 1. Each plug-in plate 11 has a plug hole 111 for the fixing pin 62 to be inserted into. The lead screw 63 is threadedly connected to the fixing pin 62. A bevel gear 611 is coaxially fixedly connected to the drive shaft 61. A bevel gear 631 is coaxially fixedly connected to the lead screw 63. The bevel gear 611 meshes with the bevel gear 631. A handwheel 612 is coaxially fixedly connected to the top of the drive shaft 61.

[0050] See attached document Figure 2 and attached Figure 3 As shown, a limit block 8 is slidably installed at the bottom of the I-beam along the vertical direction. An anti-slip plate 82 is adhered to the limit block 8. The anti-slip plate is made of hard rubber material. The limit block 8 and the flange 21 of the I-beam are in contact and cooperate with each other through the anti-slip plate 82. A second lead screw 72 is rotatably installed inside the sliding sub-rail 7. The second lead screw 72 and the drive shaft 61 are coaxially fixedly connected. The second lead screw 72 and the limit block 8 are threadedly connected. A vertically arranged guide rod 73 is fixedly connected to the sliding sub-rail 7. A guide hole 81 for the guide rod 73 to slide is opened on the top surface of the limit block 8 along the vertical direction.

[0051] After the operator completes the adjustment of the I-beam perpendicular to the length direction of the support rail 1 and along the length direction of the support rail 1, by turning the handwheel 612, the handwheel 612 can drive the lead screw 63 to rotate through the transmission shaft 61, bevel gear 611 and bevel gear 631. The lead screw 63 drives the fixing pin 62 to move, so that the fixing pin 62 is inserted into the insertion hole 111, reducing the possibility of the I-beam moving along the length direction of the support rail 1.

[0052] On the other hand, the handwheel 612 can drive the lead screw 72 to rotate through the transmission shaft 61, so that the lead screw 72 drives the limiting block 8 to move upward, so that the sliding subrail 7 and the limiting block 8 clamp the I-beam, thereby reducing the possibility of the I-beam moving along the length direction perpendicular to the support rail 1. Therefore, this support structure can limit the movement of the I-beam in two dimensions at the same time, thereby simplifying the operation steps of this support structure.

[0053] See attached document Figure 5 and attached Figure 6As shown, the fixing device 3 includes a fixing plate 31, a fixing plate 32, and two connecting screws 33. Both connecting screws 33 pass through the fixing plate 31 and the fixing plate 32, and are located on both sides of the support rail 1. The fixing plate 31 and the fixing plate 32 are located at the top and bottom of the support rail 1, respectively. Nuts 331 are provided on the opposite sides of the fixing plate 31 and the fixing plate 32, and the nuts 331 are threaded into the connecting screws 33. A limiting plate 12 and a limiting plate 13 are fixedly connected to the top surface of the support rail 1 to block the fixing plate 31. The limiting plates 12 and 13 are arranged along the length of the support rail 1. A limiting groove 311 is provided on the fixing plate 31 for the limiting plates 12 and 13 to pass through.

[0054] After the operator places the support rail 1 on the top of the building, the fixing plate 1 31 is placed on the top surface of the support rail 1, so that the limiting plate 1 12 and the limiting plate 2 13 pass through the limiting groove 311. Then, the fixing plate 2 32 is placed at the bottom of the top beam 14 on the top of the building. Next, the connecting screw 33 is passed through the fixing plate 1 31 and the fixing plate 2 32. Finally, the nut 331 is threaded onto the connecting screw 33. In this way, with the help of the top beam 14 on the top of the building, and with the obstruction of the fixing plate 1 31, the fixing plate 2 32 and the nut 331, the possibility of the support rail 1 overturning is reduced.

[0055] The implementation principle of this embodiment is as follows: Before installing the curtain wall unit panels of the building that gradually narrows from bottom to top, the operator pre-inserts the support rail 1 into the gap 41 and fixes the support rail 1 to the top of the building through the fixing device 3, so that each support rail 1 is partially suspended outside the top of the building, so as to provide support for the hoisting of the unit panels.

[0056] During use, the lifting rod 2 is slidable to adjust the horizontal distance between the lifting rod 2 and the top edge of the building, based on the actual installation position of the unit panel and the horizontal distance between the lifting rod 2 and the top edge of the building, so that the unit panel can be lifted to the predetermined installation position.

[0057] After the position of the hoisting rod 2 is adjusted, the handwheel 612 is turned so that the fixing pin 62 is inserted into the insertion hole 111. At the same time, the hoisting rod 2 is clamped by the sliding subrail 7 and the limiting block 8 to reduce the possibility of the hoisting rod 2 moving, thereby improving the safety of this support structure during use.

[0058] The embodiments described in this specific implementation 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.
