[0024] The supporting steel corbels 2 of the longitudinal keel, the transverse keel 3 and the connecting keel 4 are all rectangular steel tubes, and different specifications and models are selected according to needs.

[0025] The supporting steel corbel 2 of the longitudinal keel is arranged corresponding to the longitudinal joint of the GRC panel 1, the joint of the transverse keel 3 corresponds to the joint of the GRC panel 1, and the front end of the supporting steel corbel is welded with a rectangular steel plate. The supporting steel corbel 2 is covered with an EPDM waterproof rubber sleeve to ensure sealing.

[0027] Combination Figure 1 and Figure 3 It can be seen that the end section of the transverse keel 3 at the joint is sleeved with a round steel tube 6, and there is a small gap between the round steel tube and the transverse keel.

[0028] The round steel pipe 6 is covered with a U-shaped steel sleeve 8, a hard rubber pad 7 is arranged between the U-shaped steel sleeve and the round steel pipe, and the hard rubber pad is bonded to the round steel pipe and the U-shaped steel sleeve respectively by strong glue, so that the three become an integral part.

[0031] The two side arms of the connecting angle steel 9 are respectively connected to the U-shaped steel sleeve 8 and the connecting steel plate through bolt and nut fasteners. When connected with the U-shaped steel sleeve, the bolts pass through the two oblong holes.

[0032] The connecting steel plate 10 and the connecting angle steel 9 are connected by bolts and locked by nuts.

[0033] That is, the round steel tube, hard rubber pad and U-shaped steel sleeve integral parts are used as transverse keel connectors, and the connecting angle steel is used as the longitudinal keel connector. When the connecting angle steel is connected to the U-shaped steel sleeve, the oblong hole on the connecting angle steel can adjust the connection and fixed position of the U-shaped steel sleeve, so that the round steel tube of the transverse keel connector and the transverse keel can be eccentrically contacted, so that the transverse steel tube can be driven to rotate by rotating the transverse keel connector, and the transverse keel can be driven to adjust the installation angle through the connecting keel and L-shaped steel bar on its outer side, so as to realize different installation angle requirements of the GRC panel, so that the GRC panel can meet the changeable appearance.

The transverse keel pushes the panel outward or pulls it inward through the connecting keel and L-shaped steel bar on its outer side, thereby changing the installation angle of the panel;

[0039] (5) Tighten the nuts on the bolts between the U-shaped steel sleeve and the horizontal arm of the angle steel to position the transverse keel connector.
