Abstract
The utility model discloses a glass fiber reinforced plastic pipe, particularly a large winding angle glass fiber reinforced plastic steel pipe. The structure is orderly composed of a wrapping layer, a sand sandwiching layer, a wrapping layer and an inner lining layer from the outer part to the inner part of the pipe. The utility model is characterized in that the annular wrapping angle of the wrapping layer is 90 DEG and the screw wrapping angle is 68 to 86 DEG. The screw wrapping angle of the glass fiber reinforced plastic pipe is changed into 68 to 86 DEG from the traditional 54.75 DEG. The structural mechanics performance of the glass pipe is effectively displayed, the wrapping fiber potentiality is sufficiently displayed and the performance and the strength of the glass fiber reinforced plastic pipe is increased.
Description
The utility model relates to a kind of glass fibre reinforced plastics entwining tube, specifically is king bolt winding angle Glass Steel Tube.
The present various winding glass fibre reinforced plastics of home and abroad, many ordinary circumstance spiral winding angle is no more than 65 ° to its spiral winding angle (be commonly called as intersect winding angle) with promptly 54.75 ° of equal strength winding angles, and its equal strength theory is a hoop intensity and the ratio of axial strength is 2: 1.But facts have proved that hoop intensity is more reasonable above 10: 1 with the ratio of axial strength, can make pipeline obtain higher strength and stiffness.
The purpose of this utility model is to propose a kind of king bolt winding angle Glass Steel Tube, its spiral winding angle is changed into 68 °-86 ° by original 54.75 °, improve the strength and stiffness of glass entwining tube, overcome the existing not high enough shortcoming of glass entwining tube strength and stiffness.
Major technique content of the present utility model is, big winding angle Glass Steel Tube is from being made up of winding layer, burning into sand layer, winding layer, inside liner to pipe outside the pipe, winding layer is made of hoop winding layer and spiral winding layer, and the hoop winding angle of winding layer is 90 °, and the spiral winding angle is 68 °-86 °.
Spiral winding layer winding angle is that the axis of pipe twines the angle that fiber intersects with spiral.
Technique effect of the present utility model is, this its winding layer of king bolt winding angle Glass Steel Tube has structurally been broken the equal strength theory of existing traditional entwining tube, its winding angle is changed into 68 °-86 ° by original 54.75 °, can more effectively bring into play the structural mechanical property of glass pipe through facts have proved this glass tube, give full play to the potentiality of twining fiber, improve the performance and the intensity of fiber reinforced plastic pipe, save raw material, reduce cost.
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the structural representation of the utility model winding layer.
1 winding layer, 2 burning into sand layers, 3 winding layers, 4 inside liners, 5 tube walls, 6 spirals twine fiber, the axis of 7 pipes, α spiral winding angle.
Realize embodiment of the present utility model as shown in the figure, this king bolt winding angle Glass Steel Tube is from being made up of winding layer 1, burning into sand layer 2, winding layer 3, inside liner 4 to pipe outside the pipe, and the hoop winding angle of winding layer is 90 °, and spiral winding angle α is 68 °-86 °.
Spiral winding angle α is the axis 7 of pipe and the angle of spiral winding fiber 6.
