One end of the supporting rod 51 is fixed to the top of the supporting purlin 2, and the other end thereof passes through the insulation layer 3 and the waterproof layer of the roof and extends to the top thereof. The connecting chassis 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 supporting rod 51. Figures 1 to 10The present invention is a fully adjustable support system for adapting to a special-shaped curved roof, which 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 fixing a base plate 14 and a boss 11 arranged in the middle of the base plate 14, the boss 11 is provided with a vertically penetrating long hole 15, the boss 11 is embedded in the joint of two adjacent main keels 20, the screw rod horizontally penetrates the long hole 15 of the main keel 20 and the boss 11 and is locked and fixed by a nut, a plurality of bolts penetrate the base plate 14 and the long hole of the connecting chassis 54 and are locked and fixed, and 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] The all-round adjustable support system for adapting to the special-shaped curved roof of the present invention comprises a main keel 20, a secondary keel 30 and an adapter 10, wherein the adapter is embedded in the joint of two adjacent main keels 20, a screw rod horizontally penetrates the main keel 20 and a long hole 15 and is locked and fixed by a nut, and a plurality of screw rods penetrate the long hole of the base plate 14 and the top of the keel support 50 connected to the chassis 54 and are locked and fixed. When the main keel 20 is arranged in a divergent manner and there are different torsion angle changes, the construction personnel can rotate the adapter 10 according to the actual installation requirements to adjust its tilt angle, and can realize a rotation within a range of about 5° relative to the axis, which is used to adapt to the connection between the main keel 20 with different torsion angles and the main steel structure of the building; The vertically arranged long strip hole 15 adjusts the telescopic height of the adapter 10 relative to the main keel 20. After the adapter 10 is accurately positioned, it is locked and fixed by bolts passing through the main keel 20 and the long strip hole 15 of the boss, thereby realizing the adaptive connection between the main keel 20 of different heights and the main steel structure of the building; the secondary keel 30 is bolted to the top of the main keel 20; therefore, the all-round adjustable support system can adjust the installation position between the adapter 10 and the main keel 20 according to actual installation requirements, solves the problems of irregular torsion of the main keel 20, uneven splicing boundaries, and multiple curvature changes that lead to difficulties in adjustment and installation, is easy to install and disassemble, and improves the flexibility and accuracy of the installation and construction of special-shaped curved roofs.

[0034] like Figure 5 As shown, the end of the main keel 20 with a convex cross-section is processed into a slot 21, and the boss 11 is embedded in the slot 21 at the end of the main keel 20. The screw passes through the slot 21 of the main keel 20 and the long hole 15 of the boss 11 and is locked by a nut. An arc joint 12 is also provided on the top of the boss 11. The outer surface of the arc joint 12 close to the slot 21 is a smoothly transitional arc surface, and the net width of the arc joint 12 is greater than the width of the boss 11. The arc surface of the arc joint 12 contacts the inner wall of the slot 21 of the main keel 20, and there is a gap between the two sides of the boss 11 and the slot 21, so that the adapter 10 can rotate in the slot 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 have an anti-skid serrated surface 25. A pair of washers are respectively arranged on the outer side of the slot 21. The side of the washer close to the slot 21 of the main keel 20 is provided with a serrated surface corresponding to the anti-skid serrated surface 25. One end of the screw rod passes through the washer, the slot 21 of the main keel 20 and the boss 11 and is locked and fixed by a nut. Since the side surfaces where the slot 21 of the main keel 20 and the washer fit are both provided with serrated surfaces, the friction between the screw rod 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 joint 12 of the boss 11 is a plane. The positioning bolt 17 vertically passes through the main keel 20 and abuts against the top surface of the arc joint 12. The positioning bolt 17 cooperates with the screw to further lock the installation position of the boss 11.

[0037] like Figure 6 As shown, two pairs of long holes 141 are symmetrically arranged on both sides of the substrate 14 along its axis. Figure 7 As shown, two pairs of three long holes 541 are symmetrically arranged on both sides of the connecting chassis 54 along its axis, the number and position of the three long holes 541 correspond to the two long holes 141, and the three long holes 541 are arranged perpendicular to the two long holes 141, and a pair of four long holes 542 are also symmetrically arranged on both sides of the connecting chassis 54 along the axis, and the four long holes 542 are located between the three long holes 541 on both sides and are arranged perpendicular to the three long holes 541; Figure 8 For example, according to the installation requirements, the two elongated holes 141 arranged in the diagonal direction of the base plate 14 are bolted to the elongated holes 542 of the connecting chassis 54, and the other two elongated holes 141 of the base plate 14 are bolted to the elongated holes 541 of the connecting chassis 54. By setting elongated holes in different directions, the 360° angle adjustment between the adapter 10 and the connecting chassis 54 can be achieved, so that the adapter 10 can be rotated relative to the connecting chassis 54 to adapt to the installation requirements of different angles of the main keel 20. After the main keel 20 is positioned, the base plate 14 and the connecting chassis 54 are fastened and connected by self-tapping screws 26 to achieve the limit between the adapter 10 and the connecting chassis 54.

[0038] like Figure 1 and Fig. 9As shown, the secondary keel 30 is provided with a plurality of pairs of long holes 5 31 at intervals along the length extension direction, and the secondary keel 30 is placed on the top of the main keel 20. One side of the secondary keel 30 overlapping with the main keel 20 is connected by a bolt passing through two long holes 5 31, so that the secondary keel 30 can rotate around the connection point and adjust the installation position. When the secondary keel 30 is twisted or warped, ensure that one side of it is reliably connected, and the other side of the secondary keel 30 is connected to the main keel 20 by a self-tapping screw 26 for limiting, so that the secondary keel 30 can achieve a maximum twist of 15 mm, and can be spliced ​​with the main keel 20 at any angle.
