Multidirectional stressed plastic tensile grate, manufacturing method thereof and the plastic sheet

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.

Description

technical field [0001] The invention relates to a multi-directional stress-bearing plastic stretching grid and a manufacturing method thereof, which are used as reinforcement reinforcement materials in civil engineering or as protection and isolation materials in construction engineering. Background technique [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 ou...

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 in the shape of a well-shaped or square or rectangular hole. Compared with the grid formed by welding and weaving, this grid has better integrity and higher node strength in terms of bearing capacity, which greatly satisfies the needs of the grid. Meet the engineering requirements for the overall strength

[0003] However, in engineering applications, it is found that the actual load is often not only vertical and horizontal pressure, and the above-mentioned types of grids can only provide reinforcement and support in both vertical and horizontal directions, and the support for loads from oblique directions will show have a great weakness, they must transfer and distribute the load through the right angle shear action Song of the nodes, so the nodes are also easily damaged
