Concrete structure protective textile weaving

A concrete structure and concrete technology, applied in the direction of textiles, papermaking, textiles, fabrics, etc., can solve the problems that cannot fundamentally solve the problems of concrete structure damage, ignore engineering individual conditions, exaggerate synthetic fibers, etc., and achieve increased thickening and crack resistance effect, good economic and social benefits, and the effect of reducing the stress concentration factor

Problems solved by technology

[0002] The application of polypropylene fiber concrete has made great progress in my country's engineering and construction industry in recent years. However, some manufacturers generally have one-sidedness when promoting the effect of fibers. They think that as long as fibers are added to concrete and mortar, cracks will not exist. This view Violating the mechanism of fiber generation and ignoring the individual conditions of specific projects, the main target of synthetic fibers is the early primary cracks of concrete. Infinitely exaggerating the suppression effect of synthetic fibers on cracks is one-sided, and cannot be recovered when the structure is hit. Fundamentally solve the damage to the concrete structure

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] ①. Use high-strength and high-modulus fibers (such as Vectran, Zylon, etc. filaments) to blend with high-strength nylon fibers, the blending ratio is 40 / 60, and the yarn count is 20-40, which can make the fabric have a certain impact on the concrete structure. Reinforcement, and at the same time, it can absorb as much energy as possible when it breaks off;

[0010] ② No sizing or light sizing is required, because the yarn count is low and the warp and weft density is not high, so the weaving process of the fabric is relatively simple;

[0011] ③. During the casting process of concrete columns or guardrails, wrap the fabric on the steel frame near the outer edge. After casting, the fabric will naturally be fixed in the concrete structure (in this process, it should be noted that the distance between the fabric and the outer edge should not be too large, or Can not be too small, should be be...

Abstract

The invention provides a novel weaving idea of protecting concrete structure grid fence type fabric and process, wherein high strength high mole fabric such as filaments of Vectran and Zylon and the like and high strength nylon fiber are blended into 20-40 yarns, grid fence type fabric whose yarn density is less than 20 lines / 10cm is weaved, thereby being capable of improving the brittle failure characteristics of concrete, reducing the shrinkage crack of the concrete, increasing the toughness and impact resistant wear resistance of the concrete, simultaneously, and being capable of improving the characteristics of the concrete such as anti-permeability and antifreezing and the like. The production cost is low, the weaving process is simple, and the economic and social benefits are excellent.

Description

technical field [0001] The invention relates to a weaving method of fence-type fabrics, in particular to a weaving method of fence-type fabrics for protecting concrete structures. Background technique [0002] The application of polypropylene fiber concrete has made great progress in my country's engineering and construction industry in recent years, but some manufacturers generally have one-sidedness when promoting the effect of fibers, thinking that as long as fibers are added to concrete and mortar, cracks will not exist. This view Violating the mechanism of fiber generation and ignoring the individual conditions of specific projects, the main target of synthetic fibers is the early primary cracks of concrete. Infinitely exaggerating the suppression effect of synthetic fibers on cracks is one-sided, and cannot be recovered when the structure is hit. Fundamentally solve the damage to the concrete structure. Contents of the invention [0003] The purpose of the present inv...
