Drawings
FIG. 1 is a schematic view of a non-metallic core with a plastic protective layer.
Labeled as: the plastic deformation-resistant reinforced concrete structure comprises a reinforced core 1, a plastic protective layer 2, a reinforcing body 3, a deformation cavity 31, an adhesive 4, a bending-resistant groove 5 and a limiting groove 6.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in figure 1, a non-metal reinforced core with a plastic protective layer comprises a reinforced core 1, the reinforced core 1 comprises a plastic protective layer 2 and a reinforced body 3, the outer surface of the reinforced body 3 is covered with an adhesive 4 and is provided with a bending-resistant groove 5, the outer surface of the plastic protective layer 2 is provided with a limiting groove 6 for preventing a cable from shifting, the surface of the reinforced core is smoother, the tensile resistance and the bending performance are better by adding a plastic protective layer outside the reinforced core, the reinforced core is more attached to the inner layer of the cable after being heated, the bending-resistant groove 5 can be slightly deformed when the reinforced core 1 is bent, the stretching and the extrusion degrees of two sides of the reinforced core 1 are relieved, the bending resistance of the reinforced core 1 is improved, the limiting groove 6 can wrap the outer surface of the cable so as to play a limiting role and prevent the cable from sliding on the surface of the reinforced core 1, the adhesive 4 is made of epoxy resin, the epoxy resin material is generally used for bonding and blanking in industrial production, has stable chemical property and is not easy to deform after being cured.
In addition, as shown in fig. 1, the deformation chamber 31 is provided inside the reinforcement body 3, and when the core 1 is pressurized, the inner deformation chamber 31 can play a role of buffering, thereby improving the pressure resistance of the core 1.
On the basis, as shown in fig. 1, the reinforcement body 3 is a cylindrical structure made of aramid fiber and having a groove on the surface, and the reinforcement fiber can be made of glass fiber or aramid fiber; the glass fiber material is brittle in texture and weak in pressure resistance; the aramid fiber material is light in weight, high in strength and strong in toughness, is more corrosion-resistant than glass fiber, and the aramid fiber is used as reinforcing fiber, so that the toughness and tensile strength of the reinforcing core are improved.
On the basis, as shown in fig. 1, the bending-resistant grooves 5 are two, the two bending-resistant grooves 5 are centrosymmetric relative to the reinforcing body 3, when the reinforcing core 1 is stressed by pressure, the inner deformation cavity 31 can play a role in buffering, and the pressure resistance of the reinforcing core 1 is improved.
On this basis, as shown in fig. 1, the limiting groove 6 is an arc-shaped groove, and the arc-shaped limiting groove 6 can wrap the outer surface of the optical cable, so that the limiting effect is achieved, and the optical cable is prevented from sliding on the surface of the reinforcing core 1.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
