In a preferred embodiment, longitudinal horizontal reinforcing rods 9 are fixed at the joints among the first horizontal rod 6, the second horizontal rod 7, the first vertical reinforcing rod 3, the second vertical reinforcing rod 4 and the diagonal strut 5. Through the arrangement of the longitudinal horizontal reinforcing rods 9, the supporting stability of the clamp type triangular supporting system is further ensured.
The invention also provides a construction method of the fixture type triangular support system of the cantilever roof panel, which is shown in the figure 1 and comprises the following steps:
And 2, erecting a first vertical reinforcing rod 3 and a second vertical reinforcing rod 4 respectively adjacent to the inner side and the outer side of the shear wall 1, and enabling the first vertical reinforcing rod 3 and the second vertical reinforcing rod 4 to be supported to the roof panel 2. Specifically, since the top walkway plate of the climbing frame is flush with the roof, and the overhanging roof plate is on the same plane with the roof, so that the two conflict with each other, after the shear wall 1 is poured and before the step 2 is performed, the climbing frame is removed, and after the top walkway plate of the climbing frame is removed, the fixture type triangular support system is arranged, and then the upper concrete formwork and the next process are laid.
And 3, fixing an inclined support rod 5 between the second vertical reinforcing rod 4 and the overhanging end of the roof panel 2.
And 4, respectively penetrating a first horizontal rod 6 and a second horizontal rod 7 into the two transverse holes (for the condition that the wall bushing is fixed, the first horizontal rod 6 and the second horizontal rod 7 respectively penetrate the two wall bushings), so that the first horizontal rod 6 is connected in series with the first vertical reinforcing rod 3 and the second vertical reinforcing rod 4, extends out of the shear wall 1 and then is fixed with the inclined strut 5, and the second horizontal rod 7 is connected in series with the first vertical reinforcing rod 3 and the second vertical reinforcing rod 4, extends out of the shear wall 1 and then is fixed with the inclined strut 5. The first vertical reinforcing rods 3, the second vertical reinforcing rods 4, the first horizontal rods 6, the second horizontal rods 7 and the inclined supporting rods 5 form a stable triangular support system together, and are matched with the shear wall 1, so that the stress of the triangular support system is transmitted through the first horizontal rods 6 and the second horizontal rods 7, then the first vertical reinforcing rods 3 and the second vertical reinforcing rods 4 form a clamp to transmit the force to the shear wall 1, the reinforcing difficulty when a supporting frame cannot be erected under the roof cornice is perfectly solved, and the supporting stability is ensured.
And (5) after the step 4 is finished, the fixture type triangular support system is constructed, a cantilever roof panel can be supported, and then concrete pouring is simultaneously carried out on the roof panel and the cantilever end.

The support stability of the clamp type triangular support system is further ensured.
As a preferred embodiment: when the shear wall 1 is constructed, a diagonal embedded part is embedded at the joint of the shear wall 1 and the roof panel 2; after the construction of the shear wall 1 is completed and before the first vertical reinforcing rod 3 and the second vertical reinforcing rod 4 are erected, the climbing frame is dismantled, the outer vertical rod 11 of the climbing frame is reserved, and the inclined pull embedded part and the top end of the outer vertical rod 11 of the climbing frame are fixed by using an inclined pull rod 10. The construction platform for erecting the overhanging roof boarding is erected by the outer upright rods 11, so that materials are saved, construction steps are simplified, but considering that the single-row outer upright rods 11 are easy to shake and insufficient in stability, the stability of the outer upright rods 11 is guaranteed by the arrangement of the inclined-pulling embedded parts and the connection of the inclined-pulling rods 10, but for safety, the top walkway plate is preferably not detached temporarily when the climbing frame is detached, and the top walkway plate is detached after the inclined-pulling rods 10 are fixed, so that the outer upright rods 11 are prevented from shaking due to the fact that transverse ties are lost. Further, because the lower part of the protection net is fixed on the top walkway plate, and the protection net loses the fixing point after the top walkway plate is removed, the embodiment adopts a mode of fully hanging the safety net 12 to replace the original protection net so as to ensure safe operation and avoid people or objects from falling.
While the present invention has been described in detail and with reference to the embodiments thereof as shown in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments should not be construed as limitations of the invention, except insofar as the following claims are interpreted to cover the invention.
