The purlin support 10 includes a column 11 and an adapter. The bottom of the column 11 is connected to the main steel structure 1 of the building. The adapter consists of a sleeve 14 and a chassis 15 vertically connected to the top of the sleeve 14. The sleeve 14 of the adapter is embedded and fixed to the top of the column 11. At least one pair of long strip holes 16 are symmetrically arranged on the chassis 15 along its axis. The positioning purlin 20 includes a base plate 21 and a pair of spaced side plates 24 arranged in the middle of the base plate 21. The main keel 30 is embedded in the slot formed by a pair of side panels 24, and the screw rod transversely penetrates the bolt holes corresponding to the main keel 30 and the side panels 24 and is locked and fixed by a nut. At least one pair of long holes 25 corresponding to the position of the long hole 16 is symmetrically arranged on the base plate 21 along the axis, and the long axis of the long hole 25 is perpendicular to the long axis of the long hole 16. Multiple bolts penetrate the long holes corresponding to the base plate 21 and the chassis 15 and are locked and fixed. The secondary keel 40 is provided with multiple pairs of long holes 3 41 at intervals along the length extension direction, and the secondary keel 40 is threadedly connected to the top of the main keel 30 by bolts penetrating the long holes 3 41.

[0032] The installation and adjustment system of the free-form ceramic tile roof of the present invention comprises a purlin support 10 fixedly connected to the top of the main steel structure 1 of the building, a positioning purlin 20 movably connected to the purlin support 10, and a main keel 30 and a secondary keel 40 bolted to the top of the positioning purlin 20 in sequence. The adapter of the purlin support 10 and the base plate 21 of the positioning purlin 20 are provided with long strip holes corresponding to each other and perpendicular to each other. According to the installation requirements of the main keel 30, when the two positioning purlins 20 need to be arranged at an angle, the positions of the bolts in the adapter and the corresponding long strip holes of the base plate 21 of the positioning purlin 20 are adjusted to achieve the adjustment of the installation position and installation of the positioning purlin 20. The installation direction is improved, and the flexibility and adaptability of the assembly construction of the positioning purlin 20 and the purlin support 10 are improved; the secondary keel 40 is connected to the main keel 30 by bolts passing through the long holes, and the installation position and angle of the secondary keel 40 can be adjusted at any angle by adjusting the position of the bolts in the long holes of the secondary keel 40; therefore, the installation adjustment system realizes the position adjustment of any angle between the components by setting long holes between the positioning purlin 20 and the purlin support 10, and between the secondary keel 40 and the main keel 30 and cooperating with bolt connections, thereby adapting to the installation requirements of the free-form ceramic tile roof and improving the installation efficiency and installation accuracy.

When the secondary keel 40 is twisted or warped, it is ensured that one side has a reliable connection; after the secondary keel 40 is in place, the other side of the secondary keel 40 overlapping with the main keel 30 is connected to the main keel 30 by a self-tapping screw 42, so that the secondary keel 40 is limited to prevent it from slipping due to gravity. By providing long holes in the secondary keel 40 and cooperating with bolt connection, the secondary keel 40 can achieve a maximum twist of 15 mm, and can be spliced ​​with the main keel 30 at any angle.

[0039] Embodiment 2:

The installation and adjustment system for free-form ceramic tile roof according to claim 1, characterized in that: When two adjacent main purlins are arranged at an angle ɑ, positioning purlin one and positioning purlin two with an angle ɑ are used, and two pairs of long holes one are set along the axis of the chassis of the purlin support, and each positioning purlin is provided with a pair of long holes two, and bolts penetrate the long holes two of the positioning purlin one and the long holes one on one side of the purlin support and are locked together, and bolts penetrate the long holes two of the positioning purlin two and the long holes one on the other side of the purlin support and are locked together, and the two adjacent main purlins are bolted to the positioning purlin one and the positioning purlin two respectively.

8. The construction method of the installation and adjustment system of the free-form ceramic tile roof according to any one of claims 1 to 7, characterized in that: Here are the steps: S1: Use 3D scanning technology to re-measure the main steel structure of the building that has been installed on site, accurately adjust the 3D model of the main steel structure of the building according to the re-measurement data, extract the position information and connection data between the 3D model of the free-form ceramic tile roof and the 3D model of the main steel structure of the building, and determine the size and processing technology of each component of the installation adjustment system; determine the center coordinates of the disk at the intersection of the roof rods according to the 3D model of the main steel structure of the building, determine the ceramic tile installation positioning curve according to the 3D model of the free-form ceramic tile roof, establish a longitudinal section with the ceramic tile installation positioning curve as the path, and the intersection line of the longitudinal section and the 3D model of the main steel structure of the building is the reference line for the installation of the positioning purlin. Select several points on the reference line for the installation of the positioning purlin at intervals as the installation points of the purlin support, calculate the positioning coordinates of the two ends of each purlin support, and determine the installation direction of each purlin support according to the extension direction of the ceramic tile installation positioning curve; S2: According to the purlin support positioning coordinates obtained in step S1, the bottom of the column of the purlin support is connected to the main steel structure of the building. After the installation direction of the adapter is adjusted in place, its sleeve is embedded and fixed to the top of the column. The installation direction of the positioning purlin is adjusted according to the ceramic tile installation positioning curve, and the positioning purlin is erected on the top of the purlin support. Multiple bolts pass through the corresponding long holes of the positioning purlin and the purlin support and are locked by nuts; S3: Connect the main keel bolts to the top of the positioning purlin, and the secondary keel bolts to the top of the main keel, so that the curvature of the secondary keel is consistent with the tile installation positioning curve.

9. The construction method of the installation and adjustment system of the free-form ceramic tile roof according to claim 8, characterized in that: The step S3 also includes: a plurality of pairs of three long holes are arranged at intervals along the length extension direction of the secondary keel, the secondary keel is placed on the top of the main keel, and one side of the secondary keel overlapping the main keel is connected by a bolt passing through the three long holes. After the secondary keel is positioned, the other side of the secondary keel is connected to the main keel by a self-tapping screw.

10. The construction method of the installation and adjustment system of the free-form ceramic tile roof according to claim 8, characterized in that: The step S2 also includes: when two adjacent main purlins are arranged at an angle ɑ, two split positioning purlins 1 and 2 at the angle ɑ are used, two pairs of long holes 1 are arranged along the axis of the chassis of the purlin support, each positioning purlin is provided with a pair of long holes 2, bolts penetrate the long holes 2 of the positioning purlin 1 and the long holes 1 on one side of the purlin support and are locked together, bolts penetrate the long holes 2 of the positioning purlin 2 and the long holes 1 on the other side of the purlin support and are locked together, and the two adjacent main purlins are bolted to the positioning purlin 1 and the positioning purlin 2 respectively.
