A high-strength prestressed tapered cement pole

Abstract

This utility model relates to the field of tapered cement pole technology, and more particularly to a high-strength prestressed tapered cement pole, comprising a cement base, a wrapping mesh fixedly connected to the inner side of the cement base, reinforcing ribs fixedly connected to the cement base, and a mounting base connected to the bottom side of the cement base. The wrapping mesh includes transverse tension wires and vertical tension wires fixedly connected to the top side of the transverse tension wires. The reinforcing ribs include vertical reinforcing ribs and transverse reinforcing ribs connected to the sides of the vertical reinforcing ribs. The mounting base includes a fixed base and bolts threaded to the top surface of the fixed base. This utility model uses a low-alloy high-strength steel wrapping mesh and hot-rolled ribbed steel bars to form a three-dimensional skeleton structure, combined with PO52.5R cement pouring, to achieve synergistic enhancement of mechanical properties. The cross-weaving design of the transverse and vertical tension wires effectively disperses stress and prevents local cracking; while the introduction of transverse reinforcing ribs and transverse tension wires significantly improves the overall load-bearing capacity and deformation resistance of the pole.

Description

Technical Field

[0001] This utility model relates to the technical field of tapered cement poles, specifically a high-strength prestressed tapered cement pole. Background Technology

[0002] Conical cement poles have high strength, mainly composed of steel bars and concrete. They can bear large loads, resist external forces, and have a simple manufacturing process and low cost. They are important components used as overhead line supports in industries such as power, communications, railways, and petroleum.

[0003] Currently, most cement poles are used outdoors, where maintenance personnel frequently climb and use them. Under the influence of sun and rain, the external forces on the cement are amplified, causing cracks to appear on the surface or inside the cement poles. Cracks on tall cement poles are not easily detected, which can pose a hidden danger to maintenance personnel. Utility Model Content

[0004] To overcome the problem of cracks and potential hazards caused by external forces after long-term use of cement poles.

[0005] The present invention is as follows: a high-strength prestressed tapered cement pole, comprising a cement base, a wrapping net fixedly connected to the inner side of the cement base, a reinforcing rib fixedly connected to the cement base, and an installation base connected to the bottom side of the cement base;

[0006] The wrapping net includes horizontal wires and vertical wires fixedly connected to the top side of the horizontal wires;

[0007] The reinforcing ribs include vertical reinforcing ribs and horizontal reinforcing ribs connected to the side of the vertical reinforcing ribs;

[0008] The mounting base includes a fixed base and bolts threaded onto the top surface of the fixed base.

[0009] Preferably, the wrapping net is made of a low-alloy high-strength steel.

[0010] Preferably, the reinforcing rib is made of hot-rolled ribbed steel bar.

[0011] Preferably, the diameter of each reinforcing bar is not less than 3 cm.

[0012] Preferably, the diameter of each wire in the wrapping net is not less than 8 mm.

[0013] Preferably, the cement base is integrally cast using PO52.5R cement.

[0014] Compared with the prior art, this utility model provides a high-strength prestressed tapered cement pole, which has the following beneficial effects:

[0015] 1. This utility model uses a three-dimensional skeleton structure formed by wrapping a low-alloy high-strength steel mesh with hot-rolled ribbed steel bars and pouring it with PO52.5R cement to achieve synergistic enhancement of mechanical properties. The cross-weaving design of horizontal and vertical wires effectively disperses stress and prevents local cracking. The introduction of horizontal reinforcing ribs and horizontal wires significantly improves the overall load-bearing capacity and deformation resistance of the rod.

[0016] 2. This utility model adopts a conical structure design with a fixed base at the bottom, which conforms to the principle of mechanical transmission and is easy to install and fix. Its stability is greatly improved compared with the traditional cylindrical pole. The wrapping net, reinforcing ribs and high-strength concrete form a multi-layer composite protection system, which gives the product excellent compressive and tensile strength at the same time and effectively extends its service life. The standardized component design improves the efficiency of production and installation, and the bolt-connected base structure can realize rapid deployment and replacement.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A high-strength prestressed tapered cement pole, according to Figures 1-4 As shown, a high-strength prestressed conical cement pole includes a cement base 1, a wrapping net 2 fixedly connected to the inner side of the cement base, a reinforcing rib 3 fixedly connected to the cement base 1, and an installation base 4 connected to the bottom side of the cement base 1.

[0024] The parcel net 2 includes a horizontal wire 201 and a vertical wire 202 fixedly connected to the top side of the horizontal wire 201;

[0025] The reinforcing rib 3 includes a vertical reinforcing rib 301 and a horizontal reinforcing rib 302 connected to the side of the vertical reinforcing rib 301;

[0026] Mounting base 4 includes a fixed base 401 and bolts 402 threadedly connected to the top surface of the fixed base 401.

[0027] according to Figure 4 As shown, the material of the wrapping net 2 is a low-alloy high-strength steel.

[0028] It should be noted that low-alloy high-strength steel contains a small amount of alloying elements, while increasing the carbon and silicon content in the steel, which greatly improves the strength of the steel bars and gives them good cold bending and toughness. Currently, it is mostly used in building components under high stress.

[0029] according to Figure 3 As shown, the material of the reinforcing rib 3 is a hot-rolled ribbed steel bar.

[0030] It should be noted that hot-rolled ribbed steel bars are a type of high-strength and high-toughness steel, often used to replace ordinary carbon steel with a carbon content of 0.16%-0.25% and moderate strength and modulus of elasticity.

[0031] according to Figure 3 As shown, the diameter of each reinforcing bar 3 is not less than 3 cm.

[0032] It should be noted that this can enhance the overall strength of the cement pole, enabling it to withstand heavier and higher stress conditions.

[0033] according to Figure 2 As shown, the diameter of each wire in the wrapping net 2 is not less than 8 mm.

[0034] It should be noted that the wrapping net can enhance the tensile stress on the cement pole as a whole, thus preventing damage caused by insufficient prestress.

[0035] according to Figures 1-2 As shown, the cement base 1 is integrally cast using PO52.5R cement.

[0036] It should be noted that this type of cement has a compressive strength of up to 50-60 MPa, making it the hardest type of common cement. It has high strength and good durability, making it very suitable for heavy-duty, high-rise, or construction projects that require special durability.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
