To change it, other reinforcing profiles can also be filled in the hollow part and peripheral part of the structure, as a part of the overall structure of other composite material structures, and become a part of the building and civil structure.

Other features and functions of the present utility model can be understood in more detail after being further described in conjunction with the accompanying drawings.

As shown in the drawings, the rib structure of the embodiment of the utility model is made of resin-based composite material of fiber-reinforced thermosetting resin as a raw material, and is integrally formed by drawing, winding and repeated lamination. Among them, The thermosetting resin as the base material can be unsaturated polyester resin, epoxy resin, phenolic resin, vinyl resin and other thermosetting resins, and the fiber as the reinforcement can be glass fiber, carbon fiber, aramid fiber, high-density polyethylene fiber and other fibers. The rib structure is a slightly cage-like elongated tube cylinder, which is composed of a plurality of longitudinal ribs 11 and a plurality of ribs 12 connected between the longitudinal ribs, and formed on the peripheral wall of the tube cylinder. Hollowed-out part 13, and the radial section of this tubular body is hollow annular; The hollow radial section of this tubular tubular body can be slightly annular (as shown in Fig. 1A～Fig. 3A), elliptical annular ( 1B to 3B), three-sided rings (as shown in Figures 1C to 3C), four-sided rings (as shown in Figures 1D to 3D), and five-sided rings (as shown in Figures 1E to 3E) , hexagonal ring (as shown in FIG. 1F to FIG. 3F ), octagonal ring (as shown in FIG. 1G to FIG. 3G )... and other multilateral ring configurations.

As described above, the forming steps of the rib structure mainly include three steps: drawing the longitudinal rib 11 by drawing method, winding the rib 12 by winding method, and repeating lamination to integrally form the rib structure; the forming steps are briefly described. described as follows:

In the first step, under the pulling action of the pulling equipment, the continuous fiber impregnated with resin glue is continuously drawn longitudinally to the preset length through the forming die made according to the cross-sectional shape of the finished product, which is called Steps for pulling longitudinal tendons.

In the second step, under the rotation of the traction device, the continuous fibers impregnated with resin glue are wound around the ribs 12 of the billets that have drawn the longitudinal ribs in the forming mold to form composite material profiles with various cross-sectional shapes.
