Description
Technical Field
The invention relates to the technical field of plastic templates, in particular to a surface fiber reinforced life-prolonging plastic template structure.
Background
The plastic template, the wood template, the combined steel template, the bamboo-wood glued template and the all-steel large template are all templates used in common construction sites, have more turnover times, and can be recycled and reproduced to be a recyclable energy-saving emission-reducing environment-friendly template. According to research, the plastic template has large temperature adaptation range, strong specification adaptability, capability of being sawn and drilled and convenient use. The flatness and the smoothness of the surface of the template exceed the technical requirements of the existing fair-faced concrete template, and the template has the functions of flame retardance, corrosion resistance, water resistance and chemical corrosion resistance, and has better mechanical property and electrical insulation property. Can meet the requirements of building formworks of various cuboids, cubes, L shapes and U shapes.
At the present stage, enterprises have successively developed plastic formwork products such as glass fiber reinforced plastic formworks, sand-plastic and wood-plastic plate formworks, strong plastic PP formworks, bamboo reinforced wood-plastic formworks, PVC foamed plastic formworks and the like. The PVC plastic template has high strength, large temperature adaptation range, falling resistance and no brittleness, the static bending strength of the template reaches 22MPa, and the PVC plastic template can be normally constructed at the temperature of-20 ℃ to +60 ℃.
The cracks of the plastic material mainly develop along the plane direction of the plastic plate, and therefore need to be distributed in the plane direction of the plastic plate, but if the cracks are distributed only along the plane direction of the plastic plate, the delamination phenomenon occurs between layers, so that the connection and the reinforcement need to be performed in the plane direction (thickness direction) perpendicular to the plastic plate. However, the distribution of common short fibers in all directions is theoretically random and uniform, and although the short fibers can be reinforced in both directions, the plastic plate needs more fiber reinforcement in the plane direction, and the number required in the thickness direction is smaller, so that the efficiency is insufficient, and the cost is higher.
However, because plastics are a high polymer material, the construction site is often exposed to high temperature, so that the aging of the plastics is easily caused, cracks are expanded inwards from the surface, the service life and the use safety of the template are influenced, the fiber material is adopted to reinforce the surface of the template based on the aging characteristic of the plastics by adopting the fiber reinforced principle, the service life and the safety of the plastic template can be prolonged, and the surface fiber reinforced life-prolonging plastic template is particularly related.
