Problems solved by technology

Existing large-span bridge air guides mostly use steel structures, which are easy to process and connect, but there are also problems such as heavy weight, difficult maintenance, and easy deformation of welding, especially in marine or atmospheric corrosion environments, the surface of steel air guides needs to be regularly repaired Anti-corrosion treatment
In the actual bridge maintenance work, since the air guide device is in the cantilever state in the air, the maintenance personnel cannot reach the position of the air guide device, which brings certain difficulties to the later repair and maintenance of the bridge air guide device

Embodiment 1

[0036] Figure 1 to Figure 3 The first embodiment of the air guiding device of the present invention is shown, which includes at least one section of the air guiding section. The air guiding section includes a body composed of a top plate 1 and a bottom plate 2. An opening is provided at one end of the body, and a cavity is formed inside the body. There are reinforcing ribs in the cavity, which can enhance the overall rigidity of the body. The top plate 1 , the bottom plate 2 and the reinforcement ribs are all composed of an inner layer 13 of fiber reinforced composite material and an outer layer 14 of fiber reinforced composite material. The air guiding device of the present invention adopts the structure of the inner layer 13 of fiber reinforced composite material and the outer layer 14 of fiber reinforced composite material, which has the characteristics of light weight, high strength, corrosion resistance, environmental protection, and high rigidity, and can not only meet ...

Embodiment 2

[0047] Figure 4 The second embodiment of the air guide device of the present invention is shown. The structure of the air guide device of this embodiment is basically the same as that of Embodiment 1, the only difference is that the upper and lower ends of the side plate 4 and the main beam 10 are provided with ears. The plate 11 connects the side plate 4 and the corresponding ear plate 11 on the main girder 10 through bolts 9 to fix the wind guide segment and the main girder 10 .

[0048] The parameters in this embodiment are as follows: the length of a wind guide segment is 12m, the fiber reinforced composite material layer 13 of the top plate 1 and the bottom plate 2, the fiber reinforced composite material outer layer 14 plus the lightweight interlayer 3 have an average thickness of 25mm, wherein the fiber reinforced composite material The inner layer 13 of the material (forming the inner cavity) is 2mm thick, the outer layer 14 of fiber reinforced composite material is 3...

Embodiment 4

[0055] Figure 6 The fourth embodiment of the air guide device of the present invention is shown. The structure of the air guide device of this embodiment is basically the same as that of Embodiment 3, the only difference is that the ear plate 11 is arranged on the top plate 1 and the bottom plate 2, and the top plate 1 The lugs 11 are directly fixedly connected to the main beam 10 , and the lugs 11 of the bottom plate 2 are connected to the corresponding lugs 11 of the main beam 10 .

Abstract

The invention discloses an air guide device and a manufacturing and assembling method of the air guide device. The air guide device comprises at least one air guide section, each air guide section comprises an air guide section body composed of a top plate and a bottom plate, reinforcement ribs are arranged inside the air guide section bodies, and each of the top plates, the bottom plates and the reinforcement ribs is made of a fiber reinforcement composite material inner layer and a fiber reinforcement composite material outer layer. The manufacturing and assembling method includes the steps that (1), the fiber reinforcement composite material inner layers, the fiber reinforcement composite material outer layers and light sandwich layers are manufactured and used for forming the top plate, the bottom plate and the reinforcement rib, so that one air guide section is formed; (2), the preset number of air guide sections are manufactured and connected with a main beam of a bridge through bolts, and the air guide sections are connected through bolts. The air guide device has the advantages of being light, high in strength and corrosion performance and easy to connect with the main beam, and the manufacturing and assembling method is simple and convenient to implement.

Description

technical field [0001] The invention relates to an auxiliary structure for improving the wind resistance characteristics of a main structure, in particular to an air guiding device used in long-span bridge structures and high-rise building structures and a manufacturing and assembling method thereof. Background technique [0002] Generally, for long-span bridges, since the width and height of the girder are much smaller than the span, the bridge is significantly sensitive to wind vibration. Since the Tacoma Suspension Bridge in Washington State, USA was destroyed by wind vibration in 1940, people began to pay attention to the wind-resistant design of the bridge. In recent years, with the application of some lightweight and high-strength building materials, the sensitivity of bridges to wind has been further increased, making the problem of wind vibration of bridges more prominent. The air guide device of the bridge is a design measure taken to reduce the resonance caused by...
