[0031] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.
[0032] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.
[0033] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not have any other meaning, such as a specific order.
[0034] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.
[0035] This utility model provides a guardrail tube. The guardrail tube can be used for guardrails. Guardrails can be installed on the side of the road to separate roads.
[0036] Please refer to Figure 1The guardrail tube includes an inner liner tube 110. The inner liner tube 110 has an internal conduit. A reinforcing rib 120 is provided within the internal conduit of the inner liner tube 110. Along a first direction D1, the reinforcing rib 120 has a first end and a second end opposite to the first end. The first end of the reinforcing rib 120 is connected to the inner wall surface of the inner liner tube 110. The second end of the reinforcing rib 120 is also connected to the inner wall surface of the inner liner tube 110. The first end and the second end of the reinforcing rib 120 are spaced apart. Thus, the reinforcing rib 120 increases the strength of the guardrail tube.
[0037] It should be noted that any two of the first direction D1, the second direction D2 (described later), and the axial direction D3 of the inner liner tube 110 intersect, for example, perpendicularly. The first direction D1 and the second direction D2 (described later) are parallel to the cross-section of the inner liner tube 110. The axial direction D3 of the inner liner tube 110 is the extension direction of the inner liner tube 110. The axial direction D3 of the inner liner tube 110 is perpendicular to the cross-section of the inner liner tube 110.
[0038] like Figure 1 As shown, the guardrail tube also includes a reinforcing layer 130. The reinforcing layer 130 is fitted onto the outer periphery of the inner liner tube 110. The reinforcing layer 130 is connected to the outer periphery of the inner liner tube 110. The reinforcing layer 130 is constructed as a continuous fiber layer comprising continuous fibers. Thus, the reinforcing layer 130 can increase the strength of the guardrail tube.
[0039] like Figure 1 As shown, the guardrail tube also includes a protective layer 140. The protective layer 140 is fitted around the outer periphery of the reinforcing layer 130 and connected to the reinforcing layer 130. This protects the reinforcing layer 130. Furthermore, the protective layer 140 further increases the strength of the guardrail tube.
[0040] In this embodiment, the inner lining tube 110 of the guardrail tube is provided with reinforcing ribs 120, which can increase the strength of the guardrail tube; the reinforcing layer 130 can further increase the strength of the guardrail tube; the protective layer 140 can protect the reinforcing layer 130, and the protective layer 140 can further increase the strength of the guardrail tube; thus, the guardrail tube is not easily damaged.
[0041] Optionally, the protective layer 140 and the inner liner tube 110 can be made of the same or different materials. Specifically, one or both of the protective layer 140 and the inner liner tube 110 are constructed as a thermoplastic material layer comprising a thermoplastic material. Therefore, the guardrail tube will not rust.
[0042] The thermoplastic material layer structure includes a chlorinated polyolefin layer comprising chlorinated polyolefin, a polyethylene layer comprising polyethylene, a polypropylene layer comprising polypropylene, a POE layer comprising POE (polyethylene octene copolymer), an EPDM layer comprising EPDM (ethylene propylene diene monomer), a polyamide layer comprising polyamide, a polycarbonate layer comprising polycarbonate, a polymethyl methacrylate layer comprising polymethacrylate, an ABS layer comprising ABS (acrylonitrile butadiene styrene plastic), an SBS layer comprising SBS (styrenic block copolymers), and a SEBS (styrene ethylenebutadiene) layer. The guardrail tube comprises one of the following: a SEBS layer (styrene-ethylene-butene-styrene block copolymer), a polyethylene terephthalate layer including polyethylene terephthalate, and a polyethylene terephthalate layer including polybutylene terephthalate. This facilitates the processing of the guardrail tube.
[0043] The continuous fiber layer structure comprises one of the following: an alkali-free glass fiber layer including alkali-free glass fibers, a basalt fiber layer including basalt fibers, a carbon fiber layer including carbon fibers, and an ultra-high molecular weight polyethylene fiber layer including ultra-high molecular weight polyethylene fibers. This facilitates the selection of continuous fibers.
[0044] Optionally, the reinforcing layer 130 is constructed as a prepreg tape. The reinforcing layer 130 is constructed as a composite material layer comprising continuous fibers and the aforementioned thermoplastic material (e.g., thermoplastic resin material). The continuous fibers are fully impregnated with the thermoplastic material. Therefore, the connection strength between the inner liner tube 110 and the reinforcing layer 130 is high.
[0045] Optionally, such as Figure 1 As shown, there are multiple reinforcing ribs 120. These multiple reinforcing ribs 120 are arranged at intervals along the second direction D2. This further increases the strength of the guardrail tube.
[0046] Furthermore, the number of reinforcing ribs 120 ranges from 2 to 20.
[0047] Optionally, the reinforcing rib 120 is a sheet-like structure. The plane containing the reinforcing rib 120 is perpendicular to the second direction D2. The thickness of the reinforcing rib 120 along the second direction D2 ranges from 1 mm to 10 mm. For example, from 1.01 mm to 10 mm.
[0048] Optionally, the width of the prepreg tape of the reinforcing layer 130 ranges from 40 mm to 60 mm, for example, 50 mm. The thickness of the prepreg tape ranges from 0.1 mm to 0.3 mm, for example, 0.2 mm. This facilitates the selection of the prepreg tape.
[0049] Optionally, the content of continuous fibers in the reinforcing layer 130 ranges from 60% to 80%, for example, 70%. This results in high strength for the prepreg tape.
[0050] The angle between the extension direction of the continuous fibers of the reinforcing layer 130 (that is, the direction of winding the prepreg tape) and the axial direction D3 of the inner liner tube 110 ranges from 20° to 160°. This further increases the strength of the guardrail tube.
[0051] Optionally, such as Figure 1 As shown, the maximum dimension of the guardrail tube along its major axis is the major axis dimension of the guardrail tube. The maximum dimension of the guardrail tube along its minor axis is the minor axis dimension of the guardrail tube. The major axis dimension is greater than the minor axis dimension. The major axis direction and the minor axis direction intersect any two of the axial directions D3 of the inner lining tube body 110. For example, they are perpendicular. Therefore, the guardrail tube has high strength.
[0052] Furthermore, the cross-sectional shape of the guardrail tube is elliptical or capsule-shaped. Therefore, the guardrail tube has a simple structure.
[0053] Optionally, the major axis dimension ranges from 70mm to 700mm, and the minor axis dimension ranges from 1mm to 10mm. This results in high strength for the guardrail tubes.
[0054] Furthermore, the angle between the minor axis direction and the first direction D1 ranges from 0° to 90°. For example, the minor axis direction is parallel to the first direction D1. In this case, the major axis direction is parallel to the second direction D2.
[0055] Optionally, the wall thickness of the guardrail tubes ranges from 3mm to 9mm. This results in high strength for the guardrail tubes.
[0056] The guardrail tube of this embodiment can be processed and shaped by the following methods.
[0057] The inner liner tube 110 can be made by adding antioxidants to a thermoplastic material and continuously extruding it through an extruder.
[0058] After the inner liner tube 110 is formed, multiple layers (e.g., 20 layers) of reinforcing layers 130 can be wound around the outer periphery of the inner liner tube 110. The winding directions of the continuous fibers of two adjacent reinforcing layers 130 are different. For example, the angle between the extension direction of the continuous fiber of one of the two adjacent reinforcing layers 130 and the axial direction D3 of the inner liner tube 110 is 50°, and the angle between the extension direction of the continuous fiber of the other and the axial direction D3 of the inner liner tube 110 is 130°.
[0059] After the reinforcing layer 130 is wound, it can be heated and plasticized to connect the reinforcing layer 130 and the inner liner tube 110. After the connection between the reinforcing layer 130 and the inner liner tube 110 is completed, the protective layer 140 can be formed by an extruder. During the molding of the protective layer 140, different additives can be added to the thermoplastic material to give the protective layer 140 different functions. For example, pigments can be added to give the outer surface of the guardrail tube different colors.
[0060] The continuously produced guardrail tubes are then coiled or cut to the required length.
[0061] This utility model also provides a guardrail. The guardrail includes guardrail tubes, posts, anti-blocking blocks, and clamps.
[0062] In this embodiment, the guardrail includes a guardrail tube. The inner lining tube 110 of the guardrail tube is provided with reinforcing ribs 120, which can increase the strength of the guardrail tube. The reinforcing layer 130 can further increase the strength of the guardrail tube. The protective layer 140 can protect the reinforcing layer 130 and can further increase the strength of the guardrail tube. In this way, the guardrail tube is not easily damaged.
[0063] The clamps can be metal or plastic. During fence installation, anti-blocking blocks are added between the fence tubes and the posts. The anti-blocking blocks are connected to the fence tubes via clamps. Single fence tubes can be installed according to the fence height.
[0064] Second Implementation Method
[0065] like Figure 2 As shown, in the second embodiment, the cross-sectional shape of the inner lining tube 210, the reinforcing layer 230, and the protective layer 240 of the guardrail tube is circular.
[0066] If you need to increase the height of the guardrail, you can connect two guardrail tubes with a 250 clamp.
[0067] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described in detail here.
