Problems solved by technology

[0002] There are many production methods for plastic tensile grating, some use plastic strips to be welded into a well-shaped or square or rectangular structure, but the strength of its joints is difficult to meet the construction requirements, and often cannot play the role of reinforcement, and some use polymer The ester fiber or glass fiber is woven into a well-shaped or rectangular structure, and then coated with an organic protective layer on the surface. The node strength of this structure is also difficult to meet the strength requirements of the project, especially it is difficult to play the role of overall reinforcement. ; Some use plastic sheets to punch out a whole row of square or rectangular holes. Stretching, so as to obtain a mesh grid i

Example Embodiment

[0025] Example 1:

[0026] like figure 1 As shown in the figure, a plastic sheet with an array of holes composed of the same units extending equidistantly in the horizontal and vertical directions is formed by extrusion, and each unit contains 8 holes arranged in an octagon. The holes are located at the 8 vertices of the octagon, specifically, the centers of the 8 holes are located at the 8 vertices of the rhombus, wherein all the holes have a diameter of 5mm, and the row spacing between each octagonal unit is 9mm. The column spacing is 10 mm, and the obtained plastic sheet with hole arrays is stretched approximately three times in the longitudinal direction and the transverse direction, respectively. During the stretching process, due to the different cross-sectional areas formed between any two holes, during the processing There will be differences in the bearing capacity of the medium, and the smaller cross-sectional area is easy to be pulled apart, while the larger cross-...

[0027] Example 2:

[0028] like image 3 As shown in the figure, an array of holes is punched out of the plastic sheet, which consists of the same units that are equidistantly arranged in the horizontal and vertical directions. Each unit contains 4 holes arranged in a trapezoid shape, and the 4 holes are located in Specifically, the centers of the four holes are located at the four vertices of the trapezoid, and all the holes have a diameter of 5mm, and the row and column spacing between two adjacent trapezoid units are both 10mm. The upper bottom, the lower bottom and the height are 10mm, 11mm and 10mm respectively. The above obtained plastic sheet with hole array is stretched approximately three times in the longitudinal direction and the transverse direction. During the stretching process, due to the gap between any two holes The cross-sectional area formed between them is different, and the bearing capacity will be different during the processing process. The smaller cros...

[0029] Example 3:

[0030] like Figure 5 As shown in the figure, a plastic sheet with a hole array composed of the same units extending equidistantly in the horizontal and vertical directions is formed by extrusion. Each unit contains 4 holes arranged in a diamond shape. The 4 holes They are located at the 4 vertices of the rhombus, specifically, the centers of the 4 holes are located at the 4 vertices of the rhombus, wherein all the holes have a diameter of 4mm, the row spacing between each rhombus unit is 10mm, and the column spacing is 10mm. The above obtained plastic sheets provided with hole arrays are simultaneously stretched approximately 4 times in the longitudinal and transverse directions. During the stretching process, due to the different cross-sectional areas formed between any two holes, there will be differences in the bearing capacity during processing. , then the smaller cross-sectional area is easy to be pulled apart, while the larger cross-sectional area i...

Abstract

The invention discloses a multidirectional stressed plastic tensile grate and a manufacturing method thereof, and the multidirectional stressed plastic tensile grate is used as a ribbing and reinforcing material in the civil engineering or as a protective material and an insulated material in the constructional engineering. The multidirectional stressed plastic tensile grate manufactured by the method in the invention is an integral network structure formed by a plurality of multidirectional rib belts, and when a node synchronously bears the loads in multiple directions such as a longitudinal direction, a transverse direction, an oblique direction and the like, a plurality of rib belts connected with the node are capable of effectively dispersing the loads so that the probability that the node is subjected to tearing failure is reduced, synchronously, the integral structural strength is enhanced, and the stress condition is more reasonable. The invention also discloses a plastic sheets used for multidirectional stressed plastic tensile grate.
