Abstract
The utility model relates to a PVC (Poly Vinyl Chloride) board used for a winding pipe, which comprises a board body, wherein a plurality of reinforcing ribs arranged in parallel are arranged on the outer surface of the board body, a buckling bulge and a buckling groove are formed on two side edges of the board body, a first lapping part is arranged on the inner side of the buckling bulge, a second lapping part is arranged on the inner side of the buckling groove, an adhesive accommodating cavity is formed during the lapping process of the lapping parts, and the first lapping part and the second lapping part are mainly used for sealing in the forming process of the winding pipe. Based on the full consideration of the characteristics of the PVC (Poly Vinyl Chloride) board and the spiral winding pipe, the PVC (Poly Vinyl Chloride) board is particularly suitable for manufacturing spiral winding pipes.
Description
Technical field
The utility model relates to a kind of PVC extrusion profile, specifically a kind of PVC sheet material for the manufacture of the spiral winding pipe use.
Background technique
The base material that the manufacturing spiral winding pipe uses is extrusion board, it is PVC sheet material that one class sheet material is wherein arranged, utilize PVC sheet material to make in the process of spiral winding pipe, need to carry out bonding connection to junction plane, form preferably junction plane of a sealing effect, so the good and bad wrapped tube work that directly affects the later stage of the PVC plate construction that designs.
The model utility content
The purpose of this utility model is to provide a kind of entwining tube PVC sheet material, should meet the arts demand of sheet extrusion moulding, is convenient to again the winding shaping process in later stage, reaches above-mentioned purpose by structural optimization design.
The technical scheme in the invention for solving the technical problem is: a kind of entwining tube PVC sheet material, comprise the sheet material body, be provided with the stiffening rib of some layouts parallel to each other at the outer surface of described sheet material body, dual-side at described sheet material is respectively fastening projection and buckled recess, it is characterized in that, be the first clinch in the inboard of described fastening projection, be provided with the first projection at described the first clinch, be the second clinch in the inboard of described buckled recess, be provided with the second projection at described the second clinch, and form a binder cavity volume after the first projection and the second projection cooperate, the first clinch and the second clinch are mainly used in the sealing in the entwining tube forming process.
Sealed groove is arranged at described fastening projection top, and the bottom of described buckled recess is provided with the sealing projection, forms labyrinth seal structure after described sealed groove and sealing projection fasten, and strengthens further the sealability of lap-joint.
Described stiffening rib is T shape, is used for improving ring stiffness and intensity.
The beneficial effects of the utility model are: the utility model has taken into full account the characteristics of PVC material and the characteristics of spiral winding pipeline in the process of design, be specially adapted to make spiral winding pipe.
