Description

Technical Field

[0002] With the development of the communications industry, new facilities such as communication base stations need to be added to the angle steel towers that have been put into use. Among them, the angle steel towers with long service life and low design strength did not consider this design load at the beginning of the design, which makes the strength of the angle steel tower challenging, and the columns of the angle steel tower need to be strengthened locally. In the field of angle steel tower reinforcement, due to the variety of loads, the requirements for anti-torsion are becoming more and more numerous and more and more important. In the past, reinforcement measures focused more on the enhancement of the overall structure, and little attention was paid to the special situation of local anti-torsion requirements. However, with the increase in application scenarios, such application needs have become prominent. To solve this problem, the existing drilling and bolting or direct welding methods can still be used. However, drilling or welding will affect the foundation strength of the tower body, which is not conducive to rapid construction and is not conducive to adapting to new mounting anti-torsion requirements. Due to the lack of special design, this type of reinforcement is often not adaptable enough in current construction. Common problems include poor fit with the original structure, local drilling, complex installation operations, high costs, and inconvenience in long-term maintenance. Utility Model Content

[0042] Embodiments of the present application are described in detail below with reference to the accompanying drawings, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0043] like Figure 1-5 As shown, an anti-twisting reinforcement device for an angle steel tower is installed on a tower column of the angle steel tower. The reinforcement device includes a first profile 100, a second profile 200, a third profile 300 and a fourth profile 400.

[0044] The first end 210 of the second profile 200 is connected to the second end 120 of the first profile 100 by bending the edge, so that a bent open space is formed between the first profile 100 and the second profile 200. Usually, the two plates of the column of the angle steel tower are vertically connected. Preferably, the first end 210 of the second profile 200 is connected to the second end 120 of the first profile 100 by bending the edge vertically.

[0045] The third profile 300 includes a plane portion 310, a first end portion 320 and a second end portion 330, wherein the plane portion 310 closes the bent open space. The first end portion 320 of the third profile 300 is detachably connected to the first end portion 110 of the first profile 100, and the second end portion 330 of the third profile 300 is detachably connected to the second end portion 220 of the second profile 200, and the detachable connection is preferably a bolt connection.

[0046] As a preferred solution of the third profile 300, a certain connection angle is set between the plane portion 310 of the third profile 300 and the first end portion 320 of the third profile 300, so that the first end portion 320 of the third profile 300 is parallel to the first end portion 110 of the first profile 100; a certain connection angle is set between the plane portion 310 of the third profile 300 and the second end portion 330 of the third profile 300, so that the second end portion 330 of the third profile 300 is parallel to the second end portion 220 of the second profile 200. More preferably, the connection angle set between the plane portion 310 of the third profile 300 and the first end portion 320 of the third profile 300 is 135°; the connection angle set between the plane portion of the third profile 300 and the second end portion 330 of the third profile 300 is 135°. It can be understood that, in the above preferred embodiment, the first end 210 of the second profile 200 is connected to the second end 120 of the first profile 100 by a vertical bend of the edge. Therefore, the above-mentioned 135° connection angle is set so that the two ends of the first profile 100, the second profile 200 and the third profile 300 are parallel to each other, so as to facilitate the implementation of detachable connection means such as bolt connection thereon.

[0047] As a preferred solution of the third profile 300, the thickness of the first end 320 of the third profile 300 is greater than the thickness of the plane portion 310 of the third profile 300, so that the first end 320 of the third profile 300 is parallel to and in surface contact with the first end 110 of the first profile 100, and the plane of the second end 330 of the third profile 300 is parallel to and in surface contact with the first end 210 of the second profile 200. As a result, due to the thickening of the two ends of the third profile 300, that is, the two ends of the third profile 300 have no space gap with the first plate 100 and the second plate 200, a completely sealed state is achieved between the first plate 100, the second plate 200, and the third plate, so as to further improve its stability when installed on the angle steel tower.

[0048] The fourth profile 400 is disposed in the bent open space enclosed by the plane portion 310 of the third profile 300. The fourth profile 400 includes a first end 420 and a second end 430. The first end 420 of the fourth profile 400 is connected to the first side of the two sides of the third profile 300, and the second end of the fourth profile 400 is connected to the second side of the two sides of the third profile 300. A first installation space and a second installation space for limiting the position of the tower column are formed between the fourth profile 400 and the first profile 100 and the second profile 200. The first installation space and the second installation space are symmetrically arranged, and the fourth profile 400 and the third profile 300 have a certain gap distance.

[0049] As a preferred solution of the fourth profile 400, the first end 420 of the fourth profile 400 is connected to the first side edge of the plane portion 310 of the third profile 300, and the second end 430 of the fourth profile 400 is connected to the second side edge of the plane portion of the third profile 300. More preferably, the first end 420 of the fourth profile 400 is connected to the first end 320 of the third profile 300, and the second end 430 of the fourth profile 400 is connected to the second end of the third profile. In a parallel solution, more preferably, the first end of the fourth profile 400 is connected to the connection portion between the first side edge of the plane portion and the first end 320 of the third profile 300, and the second end of the fourth profile 400 is connected to the connection portion between the second side edge of the plane portion and the second end 330 of the third profile 300. In a parallel scheme, more preferably, the fourth profile 400 also includes a planar portion, and the planar portion 410 of the fourth profile 400 is arranged parallel to the planar portion 310 of the third profile 300 and has the certain gap distance, and the planar portion 410 of the fourth profile 400 is arranged so that the center of its plane is relative to the bending connection between the first profile 100 and the second profile 200.

[0050] As a preferred embodiment of the fourth profile 400, a certain connection angle is set between the plane portion 410 of the fourth profile 400 and the first end portion 420 of the fourth profile 400, so that the first end portion 420 of the fourth profile 400 is parallel to the first profile 100 and has a certain gap distance; a certain connection angle is set between the plane portion 410 of the fourth profile 400 and the second end portion 430 of the fourth profile 400, so that the second end portion 430 of the fourth profile 400 is parallel to the second profile 200 and has a certain gap distance. More preferably, the connection angle set between the plane portion 410 of the fourth profile 400 and the first end portion 420 of the fourth profile 400 is 135°; the connection angle set between the plane portion 410 of the fourth profile 400 and the second end portion 430 of the fourth profile 400 is 135°. It can be understood that in the above preferred solution, the first end 210 of the second profile 200 is connected to the second end 120 of the first profile 100 by vertically bending the edge, so the above setting of the 135° connection angle just makes the two ends of the first profile 100, the second profile 200 and the fourth profile 400 parallel to each other, with a certain gap distance, and the gap is the gap for accommodating and limiting the plate of the angle steel tower. The connection between the plane part connecting the four profiles and the two ends is pressed against the first profile 100 and the second profile 200 to further enhance the fixing strength with the angle steel tower plate.

[0051] Preferably, the plane portion 410 of the fourth profile 400 is arranged such that the center of its plane is opposite to the bending connection between the first profile 100 and the second profile 200. Preferably, the plane portion 310 of the third profile 300 is arranged such that the center of its plane is opposite to the bending connection between the first profile 100 and the second profile 200. Thus, the first installation space and the second installation space are symmetrically arranged.

[0052] In one solution, at least one of the first profile 100, the second profile 200, the fourth profile 200 and the fourth profile 400 is a carbon fiber profile.

[0053] In one solution, the utility model adopts a modular structure, and the reinforced components are composed of components (profiles) formed of carbon fiber materials and corresponding connecting bolts. The components formed of carbon fiber materials are closely fitted through the size and shape design of the angle steel of the angle steel tower, and spliced ​​into a stable structure with a geometric shape with an angle (mostly right angles) that conforms to the local specific angle steel tower. Bolts on the edges of the components and epoxy resin of the same system as the main material of the structure are used for bolt connection, and epoxy resin glue is added to bond them together. There is no need to punch and weld the existing tower material angle steel, and the corresponding position is directly reinforced.

[0054] The above scheme of the utility model provides a flexible selection of positions for adding loads, which better adapts to reinforcement needs. Modular profiles improve construction efficiency and adaptability, ensuring the integrity and aesthetics of the overall structure after reinforcement. Carbon fiber materials have excellent specific strength and lightweight characteristics. Their weight is only one-fourth to one-fifth of that of steel. The specific strength and specific modulus of carbon fiber composite materials are the highest among existing commonly used engineering materials. It is particularly suitable for reinforcement applications under high loads and extremely harsh environments. When faced with extreme ambient temperature changes, the carbon fiber molding material has basically no deformation and the physical properties have hardly changed. Under the same epoxy system, the carbon fiber molding material is cured through a process to ensure the bonding strength between the components and the uniformity of the overall structure, providing a scientific guarantee for long-term durability and reliability.
