A cooling tower body structure with longitudinal and transverse truss type diagonal braces

Abstract

This utility model relates to the field of cooling towers, and more particularly to a cooling tower structure using longitudinal and transverse truss-type diagonal bracing. The structure includes a tower body composed of multiple layers of transverse ring trusses. Each transverse ring truss is a double-layered reticulated shell structure. Multiple longitudinal main trusses are vertically and rotatably installed between corresponding transverse ring trusses, and diagonal support trusses are provided on adjacent longitudinal main trusses on their outer sides. By constructing a longitudinal and transverse truss-type diagonal bracing structure, a spatial three-dimensional truss-type diagonal bracing network is formed, fully utilizing the stability principle of triangles, significantly improving the overall stability of the steel structure cooling tower body, and greatly enhancing the tower body's wind resistance and seismic resistance.

Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a cooling tower structure using longitudinal and transverse truss-type diagonal bracing. Background Technology

[0002] Traditional cooling towers typically use a thin-shell reinforced concrete structure, which results in a large size and a long construction period.

[0003] With the development of technology, steel structure cooling towers are being used more and more widely, as they have the advantages of light weight and fast construction speed. However, steel structure towers usually adopt a spatial curved surface structure. When the height is large, the lateral stiffness and stability of the tower are insufficient under the action of horizontal forces such as wind loads, which poses a risk of instability and collapse. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cooling tower structure with longitudinal and transverse truss-type diagonal bracing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling tower structure with longitudinal and transverse truss-type diagonal bracing includes a tower body composed of multiple transverse ring trusses. The transverse ring trusses are double-layered grid shell structures. Multiple longitudinal main trusses are vertically rotated between corresponding transverse ring trusses, and diagonal support trusses are provided on adjacent longitudinal main trusses on the outer sides.

[0007] Furthermore, the preferred structure is that the transverse ring truss is a double-layered reticulated shell structure, and multiple horizontal struts and diagonal diagonal struts are rotatably installed along the inner axis of the transverse ring truss.

[0008] Furthermore, a preferred structure is that the longitudinal main trusses are distributed coaxially and at equal intervals along the transverse ring trusses.

[0009] Furthermore, a preferred structure is that diagonal support trusses are installed between adjacent longitudinal main trusses on the outer side.

[0010] The beneficial effects of this utility model are as follows: by constructing a longitudinal and transverse frame-type diagonal bracing structure, a spatial three-dimensional truss-type diagonal bracing network is formed, giving full play to the stability principle of triangles, significantly improving the overall stability of the steel structure cooling tower body, and greatly enhancing the wind resistance and earthquake resistance of the tower body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A cooling tower structure employing longitudinal and transverse truss-type diagonal bracing includes a tower body 1, a transverse ring truss 2, a longitudinal main truss 3, and diagonal support trusses 4. The tower body 1 is a steel structure, constructed from multiple layers of transverse ring trusses 2. The transverse ring trusses 2 are double-layered grid shell structures. Multiple horizontal support rods are rotatably installed along the axis within the transverse ring trusses 2. Diagonal diagonal support rods are set between adjacent horizontal support rods. The diagonal diagonal support rods are X-shaped, dividing the transverse ring trusses 2 into multiple triangular networks.

[0019] Between two adjacent transverse ring trusses 2, multiple longitudinal main trusses 3 are rotatably installed along the vertical axis. The longitudinal main trusses 3 are cylindrical and are distributed coaxially and equally spaced along both sides of the transverse ring trusses. An oblique support truss 4 is installed between adjacent longitudinal main trusses 3 on the outer side. The oblique support truss 4 is X-shaped and has a spherical node in the middle. A V-shaped horizontal bar is installed between one side of the node and the inner longitudinal main truss 3, dividing the steel structure space into triangles.

[0020] In this embodiment, multiple longitudinal main trusses 3 are vertically installed between the two layers of transverse ring trusses 2 by welding. Diagonal support trusses 4 are welded between adjacent longitudinal main trusses 3. The next layer of transverse ring trusses 2 is then built in the same way, and finally the tower body 1 of the cooling tower is completed.

[0021] In this invention, by constructing a longitudinal and transverse frame-type diagonal bracing structure, a spatial three-dimensional truss-type diagonal bracing network is formed, which fully utilizes the stability principle of triangles, significantly improving the overall stability of the steel structure cooling tower body and greatly enhancing the wind resistance and earthquake resistance of the tower body.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
