Preferably, the bottom of the notch is provided with a triangular spine.
Preferably, each reinforcing rib is arranged in a hollow mode, and a reinforcing pipe is arranged inside the reinforcing rib along the length direction.
Preferably, the surface of the strip material is coated with a hot melt adhesive layer; the base belt piece is internally provided with a canvas braid layer.
The utility model discloses beneficial effect does: the self-positioning requirement of the strip is met by the stepped base strip in the spiral winding process, so that the winding accuracy of the strip is guaranteed, the welding area is increased in the welding process, and the self strength of the pipe body is guaranteed. In addition, the arrangement of the reinforcing ribs improves the ring rigidity of the pipe body, the plurality of reinforcing ribs arranged in parallel achieve balance between the increase of the cross section and the light weight, and materials are saved. The preferential metal construction that has the hot melt adhesive that adopts the cladding of reinforcing locking area, consequently the butt joint area can be firm between adjacent strip gap, and the fixed band is retrained adjacent strengthening rib fixedly simultaneously to the inner wall of fixed band welds mutually with adjacent strengthening rib outer wall, thereby has promoted the wholeness ability of pipe body, like surface resistance, weatherability, ring rigidity etc.. The notch is used for collapsing, so that the splicing tape can be ensured to be smoothly and rotatably wound in a mode of being vertical to the axis of the tube body. Simultaneously, the notch is at the deformation in-process that contracts of bursting, and the triangle thorn of bottom inclines to the both sides of grafting area at random under the crooked extrusion effect of grafting area to along with winding process makes the pointed end of triangle thorn pierce inside the strengthening rib that corresponds, thereby has increased the location effect of grafting area. The reinforced pipe plays the glue stealing and occupying role in the hollow reinforced rib, so the reinforced pipe combines the material characteristic of the reinforced pipe to improve the mechanical characteristic of the reinforced rib while saving materials and lightening weight. The canvas braided layer is used for improving the tensile strength of the basic belt piece, and the hot melt adhesive layer is convenient for forming and fixing the belt material in the winding process.
