Abstract
The utility model belongs to the technical field of water supply and drainage pipeline engineering, and in particular relates to a steel bar reinforced glass fiber reinforced plastic composite tube. The structure for forming the composite tube sequentially comprises a glass fiber reinforced plastic lining layer, a glass fiber reinforced plastic structure layer, a steel bar enhancement layer and a glass fiber reinforced plastic outer protection layer from inside to outside, wherein the glass fiber reinforced plastic lining layer is made of glass fiber fabrics and resin through winding. The steel bar reinforced glass fiber reinforced plastic composite tube fully combines characteristics of glass fiber reinforced plastics and steel bar reinforced materials, so that under the premise that the advantages of good corrosion resistance, good inner wall smoothness as well as good hydraulic performance of the glass fiber reinforced plastic tube as a water delivery tube are not changed, the rigidity and the mechanical intensity of the steel bar reinforced glass fiber reinforced plastic composite tube are improved greatly, and the service life is prolonged.
Description
Technical field
The utility model belongs to the water and wastewater piping engineering technical field, is specifically related to a kind of reinforcing bar reinforcing glass steel pipe.
Background technique
Glass fibre reinforced plastics has good corrosion resistance and inner wall smooth, advantage that hydraulic performance is good, is widely used in water supply and sewage work.But the rigidity of fiber reinforced plastic pipe is lower, and material itself can produce stress relaxation and creep, exists short defective in working life.
The model utility content
The purpose of this utility model just provides a kind of reinforcing bar reinforcing glass steel pipe with higher stiffness and mechanical strength, long service life.
Realize that the technological scheme that the utility model above-mentioned purpose adopts is:
A kind of reinforcing bar reinforcing glass steel pipe, its structure comprises the frp lining layer; Outside described frp lining layer, be disposed with glass fibre reinforced plastic structure layer, reinforcing bar enhancement layer and glass fibre reinforced plastics external protection.
The additional technical feature that consists of above-mentioned reinforcing bar reinforcing glass steel pipe comprises:
---described reinforcing bar enhancement layer is one-way spiral winding layer structure;
---described reinforcing bar enhancement layer is two-way winding layer or the prefabricated reinforcement cage structure of reinforcing bar.
A kind of reinforcing bar reinforcing glass steel pipe provided by the utility model compared with prior art, have unidirectional or the reinforcing bar enhancement layer that the bidirectional screw winding forms or the reinforcing bar enhancement layer that uses the prefabricated reinforcement cage structure of reinforcing bar owing to directly use in this reinforcing bar reinforcing glass steel pipe, therefore so that rigidity, the mechanical strength of this reinforcing bar reinforcing glass steel pipe greatly improve, under not changing by the prerequisite of Glass Steel Tube as the good advantage of corrosion resistance, inner wall smooth and hydraulic performance of conduit pipe, prolonged its working life.
Description of drawings
Fig. 1 is the structural representation of reinforcing bar reinforcing glass steel pipe provided by the utility model;
Fig. 2 is the structural representation of the second reinforcing bar reinforcing glass steel pipe;
Fig. 3 is the structural representation of the third reinforcing bar reinforcing glass steel pipe.
Embodiment
Be described in further detail below in conjunction with structure and the use principle of accompanying drawing to reinforcing bar reinforcing glass steel pipe provided by the utility model:
Be illustrated in figure 1 as the structural representation of the reinforcing bar reinforcing glass steel pipe that the utility model provides.The structure that namely consists of this reinforcing bar reinforcing glass steel pipe comprises employing glasscloth and Resin Wound making frp lining layer 1 from inside to outside successively; this inside liner utilizes glasscloth, resin and sand-embedded twisting to make glass fibre reinforced plastic structure layer 2 outward; utilize the reinforcing bar winding layer 3 of the form formation of two-way winding, and utilize glasscloth, resin and sand-embedded twisting to make glass fibre reinforced plastics external protection 4.
In the structure of above-mentioned reinforcing bar reinforcing glass steel pipe, the reinforcing bar enhancement layer can also be set to the prefabricated reinforcement cage structure of reinforcing bar that is made of some circumference muscle 5 and axial ribs 6 as shown in Figure 2, this structure composite pipe axially and the intensity of hoop greatly strengthen; The reinforcing bar enhancement layer can also be set to the one-way spiral winding layer structure that formed by single steel bar 7 as shown in Figure 3.Wherein the reinforcing bar reinforcing glass steel pipe that consists of of as shown in Figure 3 one-way spiral winding layer has good bending properties, can bring great convenience to construction.
The reinforcing bar enhancement layer of above-mentioned reinforcing bar reinforcing glass steel pipe also can be compiled into as required reinforcement cage and directly be embedded in and carry out in the glass fibre reinforced plastic structure axially and the hoop enhancing.
