Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0035] In order to explain the specific structure of the present invention in detail, please refer to Figure 1 Combined with Figure 2 As shown, a carbon fiber reinforcement device for beams and slabs of building structures of the present invention comprises a vehicle body 1, a telescopic connecting arm 200 and an installation arm 300, wherein a traveling wheel is installed at the bottom of the vehicle body 1, the connecting arm 200 and the installation arm 300 are respectively installed at both ends of the vehicle body 1, a tension frame 18 with a tension roller 19 is installed on the connecting arm 200, and a pressure roller 14 is installed at the end of the connecting arm 200; and a magnetic suction cup 10 is installed at the end of the installation arm 300.

[0036] In order to improve the laying efficiency, the present invention is equipped with a rotating disk 11 at the bottom of the vehicle body 1, and a track wheel 13 is installed on the rotating disk 11, and a magnet 12 is installed on the track wheel 13.

[0037] Specifically, the connecting arm 200 of the present invention includes a first curved arm 23, a second curved arm 17 and a telescopic joint 24 / 21. The first curved arm 23 is hinged on both sides of the vehicle body 1 through a rotating shaft 25. The telescopic joint 24 / 21 is respectively arranged in the middle of the first curved arm 23 and the second curved arm 17. The end of the first curved arm 23 is connected to the second curved arm 17 through a universal joint 22, and the tension frame 18 is installed on the second curved arm 17.

[0038] like Figure 2 As shown, a pressure roller shaft 15 is installed between the second crank arms 17 of the present invention, and a pressure roller 14 is installed on the pressure roller shaft 15.
