Description

Technical Field

[0001] This invention relates to the field of building decoration construction technology, and in particular to an all-around adjustable support system adapted to irregular curved roofs and its installation method. Background Technology

[0002] As the fifth facade of a building, the roof plays a crucial role in large stadiums, offering a rich variety of decorative effects through different materials and shapes. Modern newly constructed stadiums often feature irregularly shaped, curved, or polyhedral roofs. Based on the main grid shell structure, the components of the curtain wall assembly system are irregularly distributed, requiring profiles as the keel for installation. When the keel experiences significant torsion or angles in different directions, traditional curtain wall assembly systems are no longer suitable for the changes in irregular curved structures. Different sizes of adapters are needed between the components for adjustment and installation, increasing processing and installation difficulty and making it hard to control installation precision, thus failing to meet the installation requirements of irregular curved roofs. Summary of the Invention

[0003] The present invention addresses the challenges of fabricating and installing the connecting parts between components in existing curtain wall assembly systems for irregularly shaped curved roofs, which are difficult to control in terms of installation accuracy. The purpose of this invention is to provide a fully adjustable support system adapted to irregularly shaped curved roofs and its installation method.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an all-round adjustable support system adapted to irregular curved roofs, including: main keel, secondary keel and adapter, the adapter is formed by a base plate and a boss set in the middle of the base plate, the boss has a vertical through-hole, the boss is embedded in the splice of two adjacent main keels, the screw passes through the elongated hole of the main keel and the boss laterally and is locked by a nut, multiple bolts pass through the elongated hole of the connecting base plate of the base plate and the keel support and are locked, and the secondary keel is bolted to the top of the main keel.

[0005] This invention relates to an all-around adjustable support system for irregularly shaped curved roofs. It includes main keels, secondary keels, and adapters. The adapter's boss is embedded at the joint of two adjacent main keels. A bolt passes laterally through elongated holes in the main keel and the boss, and is secured by a nut. Multiple bolts pass through elongated holes in the base plate and connecting chassis, and are also secured. When the main keels are arranged in a divergent pattern and have different torsion angles, construction personnel can rotate the adapter to adjust its tilt angle according to actual installation needs. It can achieve rotation within approximately 5° relative to the axis, accommodating the connection between the main keels and the main steel structure of the building at different torsion angles. Utilizing vertical... The adjustable adapter, with its height relative to the main keel, is positioned via an elongated hole. After precise positioning, the adapter is secured by bolts through the elongated hole, which passes through both the main keel and the boss. This achieves an adaptive connection between the main keel and the building's main steel structure at different heights. The secondary keel is bolted to the top of the main keel. Therefore, this omnidirectional adjustable support system can adjust the installation position between the adapter and the main keel according to actual installation needs. It solves the problems of irregular torsion of the main keel, inconsistent splicing joints, and numerous curvature variations that lead to difficulties in adjustment and installation. It is easy to install and disassemble, improving the flexibility and accuracy of installation on irregular curved roofs.

[0006] Furthermore, the boss is embedded in the slot at the end of the main keel, and the screw passes through the slot of the main keel and the elongated hole of the boss and is locked together by the nut. The top of the boss is also provided with an arc-shaped connector. The outer surface of the arc-shaped connector near the slot is a smoothly transitioned arc surface, and the net width of the arc-shaped connector is greater than the width of the boss. The arc surface of the arc-shaped connector is in contact with the inner wall of the slot of the main keel.

[0007] Furthermore, the adapter also includes a pair of washers. The outer side of the main keel end slot does not have an anti-slip serrated surface. The pair of washers are respectively set on the outer side of the slot. The side of the washers near the main keel slot has a serrated surface corresponding to the anti-slip serrated surface. One end of the screw passes through the washers, the main keel slot and the boss and is locked and fixed by a nut.

[0008] Furthermore, the adapter also includes a positioning bolt, the top surface of the arc-shaped connector of the boss is flat, and the positioning bolt passes vertically through the main keel and abuts against the top surface of the arc-shaped connector.

[0009] Furthermore, two pairs of elongated holes 2 are symmetrically arranged on both sides of the base plate along its axis, and two pairs of elongated holes 3 are symmetrically arranged on both sides of the connecting base of the keel support along its axis. The number and position of the elongated holes 3 correspond to the elongated holes 2, and the elongated holes 3 are perpendicular to the elongated holes 2. A pair of elongated holes 4 are also symmetrically arranged on both sides of the connecting base along its axis. The elongated holes 4 are located between the elongated holes 3 on both sides and are perpendicular to the elongated holes 3. Bolts pass through the elongated holes 2 on the base plate and the elongated holes 3 and 4 on the connecting base and are locked and fixed, so that the adapter can rotate relative to the connecting base to adapt to the installation requirements of the main keel. After the main keel is positioned, the base plate and the connecting base are fastened together by self-tapping screws.

[0010] Furthermore, the secondary keel is provided with multiple pairs of elongated holes five at intervals along its length extension direction. The secondary keel rests on the top of the main keel. One side of the secondary keel and the main keel overlaps and is connected by bolts passing through the elongated holes five. The other side of the secondary keel is connected to the main keel by self-tapping screws.

[0011] In addition, the present invention also provides an installation method for an all-around adjustable support system adapted to irregular curved roof surfaces, the steps of which are as follows:

[0012] S1: Adjust the three-dimensional model of the main steel structure of the building according to the re-measurement data, determine the coordinates of the keel support through the three-dimensional model of the main steel structure of the building, and position and install the keel support on the construction site;

[0013] S2: Determine the installation positions of the main keel and secondary keel according to the 3D model of the irregular curved roof and the coordinates of the connecting base. Pre-assemble the main keel and set the adapter between two adjacent main keels. The boss of the adapter is embedded in the splice between two adjacent main keels. Adjust and position the main keel according to the 3D model of the irregular curved roof. The screw passes through the long hole of the main keel and the boss of the adapter and is locked and fixed by the nut. The base plate is bolted to the connecting base of the keel support. Connect it to the top of the supporting purlin according to the coordinates of the connecting base obtained in step S1.

[0014] S3: Place the secondary keel frame on top of the main keel and bolt it to the main keel.

[0015] The installation method of the all-around adjustable support system for irregular curved roofs of the present invention involves first determining the coordinates of the connecting base according to the re-measured and adjusted three-dimensional model of the main steel structure of the building, then positioning and installing the connecting base on site, pre-assembling the main keel, embedding the adapter between two adjacent main keels, adjusting and positioning the main keel according to the three-dimensional model of the irregular curved roof, and locking the bolts through the elongated holes of the main keel and the boss with nuts. The base plate is bolted to the connecting base, and finally, the keel support is welded to the top of the supporting purlin. Because the main keel, secondary keel and adapter adopt a fastener threaded connection structure, disassembly and assembly are convenient, reducing the installation difficulty of the curtain wall support system for irregular curved roofs, reducing later maintenance costs, and solving the problems of adjustment and installation difficulty caused by irregular torsion of the main and secondary keels, inconsistent splicing boundaries, and multiple curvature changes. Moreover, the support system can adapt to the installation deviation of the main steel structure of the building, improving the installation accuracy.

[0016] Furthermore, step S2 also includes: before locking the adapter, rotating the adapter to make its slope consistent with the corresponding installation position on the purlin support, moving the adapter vertically to make the installation height of the main keel meet the construction requirements, and after the installation position of the adapter is determined, the screw passes through the long hole of the main keel and the boss horizontally and is locked and fixed by the nut, and the positioning bolt passes through the main keel vertically and abuts against the top of the arc-shaped joint of the boss.

[0017] Furthermore, step S2 also includes: rotating the base plate and the connecting base plate so that the base plate and the connecting base plate can adapt to the irregular curved surface of the main steel structure of the building; multiple bolts passing through the elongated hole two on the base plate and the elongated hole three and elongated hole four on the connecting base plate and locking them in place; and welding the keel support to the top of the supporting purlin.

[0018] Furthermore, step S3 also includes: the secondary keel is provided with multiple pairs of elongated holes five at intervals along its length extension direction, the secondary keel is placed on top of the main keel, one side of the secondary keel and the main keel overlaps is connected by bolts passing through the elongated holes five, and the other side of the secondary keel is connected to the main keel by self-tapping screws.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention. For ease of description, the terms "upper" and "lower" used below are consistent with the upper and lower directions in the drawings, but this should not be construed as a limitation of the technical solution of the present invention.

[0032] This embodiment takes the construction of an irregular curved roof as an example. The top of the main steel structure of the building is connected to the supporting purlin 2, and the keel support 50 is connected to the top of the supporting purlin 2. The keel support 50 includes a support rod 51, a sleeve 52, and a connecting base 54. One end of the support rod 51 is fixed to the top of the supporting purlin 2, and the other end passes through the roof insulation layer 3 and waterproof layer and extends to its top. The connecting base 54 is vertically connected to one end of the sleeve 52, and the other end of the sleeve 52 is sleeved or embedded in the support rod 51. The following is in conjunction with Figures 1 to 10This invention describes an all-around adjustable support system adapted to irregularly shaped curved roofs. It includes: a main keel 20, a secondary keel 30, and an adapter 10. The adapter 10 is connected to the top of the keel support 50. The adapter 10 is formed by a base plate 14 and a boss 11 located in the middle of the base plate 14. The boss 11 has a vertically penetrating elongated hole 15. The boss 11 is embedded at the joint of two adjacent main keels 20. A screw passes laterally through the elongated hole 15 of the main keel 20 and the boss 11 and is locked in place by a nut. Multiple bolts pass through the elongated holes of the base plate 14 and the connecting base 54 and are locked in place. The secondary keel 30 is bolted to the top of the main keel 20. In this embodiment, the cross-section of the secondary keel 30 is T-shaped, and the cross-section of the main keel 20 is convex.

[0033] This invention relates to an all-around adjustable support system for irregularly shaped curved roofs. It includes a main keel 20, secondary keels 30, and a connector 10. The connector is embedded at the joint of two adjacent main keels 20. A screw threaded laterally through the main keel 20 and an elongated hole 15, and secured with a nut. Multiple screws threaded through the base plate 14 and the elongated hole connecting the top of the keel support 50 to the base plate 54, and are also secured. When the main keels 20 are arranged in a divergent pattern and exhibit different torsion angles, construction personnel can rotate the connector 10 to adjust its tilt angle according to actual installation requirements. This allows for rotation within approximately 5° relative to the axis, accommodating the connection between the main keels 20 and the main steel structure of the building at different torsion angles. The vertically arranged elongated hole 15 adjusts the telescopic height of the adapter 10 relative to the main keel 20. After the adapter 10 is precisely positioned, it is locked and fixed by bolts that pass through the main keel 20 and the elongated hole 15 of the boss, realizing an adaptive connection between the main keel 20 and the main steel structure of the building at different heights. The secondary keel 30 is bolted to the top of the main keel 20. Therefore, this all-round adjustable support system can adjust the installation position between the adapter 10 and the main keel 20 according to the actual installation requirements, solving the problems of irregular torsion of the main keel 20, inconsistent splicing boundaries, and many curvature changes that lead to difficulties in adjustment and installation. It is easy to install and disassemble, and improves the flexibility and accuracy of the installation construction of irregular curved roofs.

[0034] like Figure 5 As shown, the end of the main keel 20 with a convex cross-section is machined into a groove 21. The boss 11 is embedded in the groove 21 at the end of the main keel 20. The screw passes through the groove 21 of the main keel 20 and the elongated hole 15 of the boss 11 and is locked by a nut. The top of the boss 11 is also provided with an arc-shaped connector 12. The outer surface of the arc-shaped connector 12 near the groove 21 is a smooth arc surface, and the net width of the arc-shaped connector 12 is greater than the width of the boss 11. The arc surface of the arc-shaped connector 12 contacts the inner wall of the groove 21 of the main keel 20. There is a gap between the two sides of the boss 11 and the groove 21, so that the adapter 10 can rotate in the groove 21.

[0035] like Figure 5 As shown, the adapter 10 also includes a pair of washers. The outer side of the slot 21 at the end of the main keel 20 does not yet have an anti-slip serrated surface 25. A pair of washers are respectively disposed on the outer side of the slot 21. The washers have serrated surfaces corresponding to the anti-slip serrated surfaces 25 on the side closest to the slot 21 of the main keel 20. One end of the screw passes through the washers, the slot 21 of the main keel 20, and the boss 11, and is locked in place by a nut. Because serrated surfaces are added to the sides where the slot 21 of the main keel 20 and the washers meet, the friction between the screw and the main keel 20 is increased, making the connection between the adapter 10 and the main keel 20 more stable.

[0036] like Figure 5 As shown, the adapter 10 also includes a positioning bolt 17. The top surface of the arc-shaped connector 12 of the boss 11 is a plane. The positioning bolt 17 passes vertically through the main keel 20 and abuts against the top surface of the arc-shaped connector 12. The positioning bolt 17, together with the screw, further locks the installation position of the boss 11.

[0037] like Figure 6 As shown, two pairs of elongated holes 141 are symmetrically arranged on both sides of the substrate 14 along its axis, as... Figure 7 As shown, two pairs of elongated holes 541 are symmetrically arranged along the axis on both sides of the connecting base 54. The number and position of the elongated holes 541 correspond to those of the elongated holes 141, and the elongated holes 541 are perpendicular to the elongated holes 141. A pair of elongated holes 542 are also symmetrically arranged along the axis on both sides of the connecting base 54. The elongated holes 542 are located between the elongated holes 541 on both sides and are perpendicular to the elongated holes 541. In this embodiment... Figure 8 For example, according to installation requirements, two elongated holes 141 arranged diagonally on the base plate 14 are bolted to the elongated hole 542 on the connecting base 54. Two other elongated holes 141 on the base plate 14 are bolted to the elongated hole 541 on the connecting base 54. By setting elongated holes in different directions, the angle between the adapter 10 and the connecting base 54 can be adjusted 360°, allowing the adapter 10 to rotate relative to the connecting base 54 to adapt to different installation angles of the main keel 20. After the main keel 20 is positioned, the base plate 14 and the connecting base 54 are fastened together with self-tapping screws 26, thus limiting the movement between the adapter 10 and the connecting base 54.

[0038] like Figure 1 and Figure 9As shown, the secondary keel 30 is provided with multiple pairs of elongated holes 31 at intervals along its length extension direction. The secondary keel 30 rests on the top of the main keel 20. One side of the secondary keel 30 and the main keel 20 overlaps and is connected by bolts passing through two elongated holes 31, so that the secondary keel 30 can rotate around the connection point and adjust its installation position. When the secondary keel 30 twists or warps, it ensures that one side has a reliable connection. The other side of the secondary keel 30 is connected to the main keel 20 by self-tapping screws 26 for limiting, so that the secondary keel 30 can achieve a maximum twist of 15mm and splicing with the main keel 20 at any angle.

[0039] Combination Figures 1 to 10 The installation method of the omnidirectional adjustable support system for irregular curved roofs according to the present invention is described in detail below:

[0040] S1: Use a 3D scanning robot or total station to re-measure the main steel structure of the building on site. Adjust the three-dimensional model of the main steel structure of the building based on the re-measurement data. Determine the number, length, quantity, and angle of the keel support 50 through the three-dimensional model of the main steel structure of the building and form coordinates and forms. Position and install the keel support 50 on the construction site according to the coordinates and forms.

[0041] S2: Determine the installation positions of the main keel 20 and secondary keel 30 based on the three-dimensional model of the irregular curved roof and the coordinates of the connecting base 54 of the keel support 50. Pre-assemble the main keel 20, place the adapter 10 between two adjacent main keels 20, and embed the boss 11 of the adapter 10 at the splice between two adjacent main keels 20. Adjust and position the main keel 20 according to the three-dimensional model of the irregular curved roof. The screw passes through the elongated hole 15 of the main keel 20 and the boss 11 laterally and is locked and fixed by the nut. The base plate 14 is bolted to the connecting base 54. Weld the keel support 50 to the top of the supporting purlin 2 according to the coordinates of the keel support 50 obtained in step S1.

[0042] S3: The secondary keel 30 is placed on top of the main keel 20 and bolted to the main keel 20.

[0043] The installation method of the all-around adjustable support system for irregular curved roofs of the present invention involves first determining the coordinates of the keel support 50 based on the re-measured and adjusted three-dimensional model of the main steel structure of the building, and then positioning and installing the keel support 50 on site. The main keel 20 is pre-assembled, and the adapter 10 is embedded between two adjacent main keels 20. The main keel 20 is adjusted and positioned according to the three-dimensional model of the irregular curved roof. A screw is laterally inserted through the elongated hole 15 of the main keel 20 and the boss 11 and locked in place by a nut. The base plate 14 is bolted to the keel support. The connecting base 54 of 50 is then connected to the keel support 50, which is then welded to the top of the supporting purlin 2. Because the main keel 20, secondary keel 30 and adapter 10 are connected by a fastener threaded connection structure, disassembly and assembly are convenient, reducing the installation difficulty of the irregular curved roof curtain wall support system, reducing the later maintenance cost, and solving the problems of irregular torsion, inconsistent splicing boundaries and multiple curvature changes of the main and secondary keels 30, which lead to adjustment and installation difficulties. Moreover, the support system can adapt to the installation deviation of the main steel structure of the building, improving the installation accuracy.

[0044] Step S2 also includes, for example Figure 5 As shown, before the adapter 10 is locked, the adapter 10 is rotated so that its slope is consistent with the corresponding installation position on the main steel structure of the building. The adapter 10 is moved vertically, and the extension height of the adapter 10 relative to the main keel 20 is adjusted by using the elongated hole 15 of the vertically set boss 11, so that the installation height of the main keel 20 meets the construction requirements. After the installation position of the adapter 10 is determined, the screw passes horizontally through the elongated hole 15 of the main keel 20 and is locked and fixed by the nut. The positioning bolt 17 passes vertically through the main keel 20 and abuts against the top of the arc-shaped joint 12 of the boss 11.

[0045] Step S2 further includes rotating the base plate 14 and the connecting base plate 54 so that the base plate 14 and the connecting base plate 54 can adapt to the irregular curved surface of the main steel structure of the building. Multiple bolts pass through the elongated hole 141 of the base plate 14 and the elongated hole 541 and elongated hole 542 of the connecting base plate 54 and lock them in place. Finally, the keel support 50 is welded to the top of the supporting purlin 2.

[0046] Step S3 further includes that the secondary keel 30 is provided with multiple pairs of elongated holes 31 at intervals along its length extension direction, the secondary keel 30 is placed on top of the main keel 20, and one side of the secondary keel 30 overlapping with the main keel 20 is connected by bolts passing through two elongated holes 31, so that the secondary keel 30 can rotate around the connection point and adjust the installation position. When the secondary keel 30 twists or warps, it is ensured that one side has a reliable connection. The other side of the secondary keel 30 is connected to the main keel 20 by self-tapping screws 26 for limiting, so that the secondary keel 30 can achieve a maximum twist of 15mm and splicing with the main keel 20 at any angle.

[0047] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the claims.
