Description

Technical Field

[0001] This utility model relates to the field of arch bridge tower construction engineering technology, and in particular to a tower that is easy to assemble and disassemble. Background Technology

[0002] Currently, the common method used in arch bridge construction is to symmetrically hoist the main arch steel pipes from both sides of the riverbank into sections for cantilever assembly, culminating in the central closure to form the arch ring. The hoisting equipment used is a cable crane with a tower. The tower provides stable support for the cable crane. Typically, anchor boxes for securing the steel strands are bolted to the tower. Before closure, the steel strand cables that diagonally secure the half-span cantilever steel pipe arch ring are connected to one end of the anchor box. The other end of the anchor box is connected to the steel strand back cable (such as...) which is connected to the rock anchor. Figure 1 (As shown).

[0003] In existing technology, the tower of a cable crane is mainly composed of columns and web members. The connection method is as follows: several columns are vertically installed on the ground; the web members are inclined between adjacent columns to ensure the overall stability of the tower and improve its load-bearing capacity. During tower assembly, construction workers weld and fix the two ends of the web members to the columns. After the project is completed, construction workers often use gas cutting or flame cutting to cut the web members and dismantle the tower.

[0004] Therefore, the columns, web members, and other components dismantled from the tower cannot be reused directly. The cut parts must be trimmed and polished; otherwise, it would pose a safety threat to construction workers. This leads to problems such as increased construction costs, slow project progress, and low construction efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0040] In existing technologies, the common method used in arch bridge construction is to symmetrically hoist the main arch steel pipes from both sides of the riverbank into cantilevered sections, culminating in the central closure to form the arch ring. The hoisting equipment typically uses a cable crane with a tower. The tower provides stable support for the cable crane. Anchor boxes for securing the steel strands are usually bolted to the tower. Before closure, the steel strand cables that diagonally secure the half-span cantilevered steel pipe arch ring are connected to one end of the anchor box. The other end of the anchor box is connected to the steel strand back cable (such as...) which is attached to the rock anchor. Figure 1 (As shown). Therefore, during the installation of the main arch steel pipe by the cable crane, the steel bundles and back cables of the inclined main arch ring are connected and tensioned through the anchor box device installed on the tower, which can ensure the stability and stress balance of the tower.

[0041] Currently, the tower of a cable crane is mainly composed of columns and web members. The connection method is as follows: several columns are vertically installed on the ground; the web members are installed at an angle between adjacent columns to ensure the overall stability of the tower and improve its load-bearing capacity. During tower assembly, construction workers weld and fix the two ends of the web members to the columns. After the project is completed, construction workers often use gas cutting or flame cutting to cut the web members and dismantle the tower.

[0042] This means that components such as columns and struts removed from the tower cannot be reused directly. The cut parts must be trimmed and polished, otherwise it would pose a safety threat to construction workers. Furthermore, it also leads to increased construction costs, slower project progress, and lower construction efficiency.

[0043] To address the aforementioned problems, this utility model provides an easily assembled and disassembled tower.

[0044] like Figures 2 to 7 As shown, the tower includes a column structure 400, a web structure 600, and a lug assembly 500. The column structure 400 and the web structure 600 are assembled into one unit by the lug assembly 500.

[0045] The column structure 400 is composed of several vertically extending columns 410, stacked sequentially from the ground upwards. Ear plate assemblies 500 are disposed on the outer periphery of the columns 410. The web structure 600 includes several web members 610. The web members 610 are detachably connected to the ear plate assemblies 500. Each web member 610 is a straight rod. Both ends of each web member 610 extend to two adjacent columns 410.

[0046] Specifically, the column structure 400 consists of multiple columns 410, which are stacked vertically to form the main support part of the tower. Each column 410 is equipped with an ear plate assembly 500 for connecting to the web members 610.

[0047] The web structure 600 includes various types of web members 610. For example, there are first web members 611 and second web members 612 distributed horizontally, and third web members 613 distributed vertically. They are connected to the columns 410 via ear plate assemblies 500, enhancing the overall stability and structural strength of the tower.

[0048] Correspondingly, the lug assembly 500 includes a vertical lug 510 and a horizontal lug 520. They are detachably connected to the web member 610. Furthermore, the vertical lug 510 and the horizontal lug 520 are distributed circumferentially along the column 410.

[0049] In this embodiment, by providing an ear plate assembly 500 on the outer peripheral wall of the column 410, the web member 610 and the column 410 can be easily assembled and disassembled, and each part can be reused. This not only improves the assembly and disassembly efficiency of the tower, but also reduces the purchase cost of tower parts. The tower structure is simple, the construction operation is safe, the construction efficiency is high, and the construction progress can be accelerated.

[0050] Based on the above embodiments, another embodiment of this utility model introduces an easy-to-assemble and disassemble tower.

[0051] like Figure 6 and Figure 7As shown, the ear plate assembly 500 includes a vertical ear plate 510. The surface of the vertical ear plate 510 is parallel to the axial section of the column 410 and extends outward from the peripheral sidewall of the column 410.

[0052] Furthermore, the vertical ear plate 510 can be arranged on the side of the column 410 at different angles, increasing the selectivity of the connection position of the web member 610. This allows for the installation of the vertical ear plate 510 and connection of the web member 610 whenever a web member 610 needs to be added to enhance stability in any part of the tower, thereby improving the flexibility and adaptability of the tower.

[0053] The vertical lug 510 simplifies the tower assembly process. When installing the web member 610, simply align the web member 610 with the vertical lug 510 and secure it with pins or other fasteners. This speeds up tower assembly, prevents incorrect installation, and reduces construction difficulty.

[0054] Based on the above embodiments, another embodiment of the present invention introduces an ear plate assembly 500.

[0055] like Figure 3 and Figure 6 As shown, the column 410 has at least two vertical lugs 510 at the same axial position, and the angle between adjacent vertical lugs 510 along the circumference of the column 410 is a right angle. This design can provide better lateral support for the column 410 and improve the stability of the column 410.

[0056] Furthermore, such as Figure 6 As shown, the ear plate assembly 500 also includes a horizontal ear plate 520. The surface of the horizontal ear plate 520 is perpendicular to the axial section of the column 410 and extends outward from the peripheral sidewall of the column 410.

[0057] Furthermore, along the axial direction of the column 410, the midpoints of the horizontal ear plate 520 and the vertical ear plate 510 are aligned. Along the circumference of the column 410, the midpoint of the horizontal ear plate 520 lies on the bisector of the angle between two adjacent vertical ear plates 510 along the circumference of the column 410. This ensures consistent spacing between the ear plate assemblies 500 in the tower, preventing misalignment of the connection holes between the web member 610 and the ear plate, thus avoiding installation difficulties. It also allows the ear plate assembly 500 to effectively transmit the force from the web member 610, ensuring a more uniform force distribution on the column 410, reducing local stress concentration, and improving the structural strength of the tower.

[0058] Based on the above embodiments, another embodiment of this utility model introduces a tower with a simple structure and easy assembly. Specifically, the column structure 400 is distributed at equal intervals in both the horizontal and vertical directions, forming a grid pattern. This layout can evenly distribute the forces borne by the tower, ensuring the stability of the tower in all directions, thereby better resisting wind loads or other external forces from different directions.

[0059] The web member 610 includes a first web member 611. The first web member 611 extends horizontally in both the transverse and vertical directions. Furthermore, the first web member 611 is connected to the vertical lug 510. The horizontally arranged first web member 611 effectively counteracts forces in the horizontal direction.

[0060] Furthermore, the web member 610 includes a second web member 612. The second web member 612 extends in an inclined direction within a vertical plane. The second web member 612 is connected to the vertical lug 510. The web member 610 also includes a third web member 613. The third web member 613 extends horizontally along a diagonal direction. The third web member 613 is connected to the vertical lug 510.

[0061] The arrangement of the second web member 612 and the third web member 613 along the diagonal not only enhances the lateral and vertical stability of the tower, but also improves the overall rigidity of the tower.

[0062] Based on the above embodiments, another embodiment of this utility model introduces an easy-to-assemble and disassemble tower.

[0063] The ear plate assembly 500 is hinged to the web member 610 via a pin. Pin holes are provided on the surfaces of the vertical ear plate 510 and the horizontal ear plate 520. Pin holes are provided at both ends of the web member 610.

[0064] To enhance the connection strength between the lug plate and the web member 610 and improve the tensile strength it can withstand, the lug plate assembly 500 also includes a reinforcing washer 530. The reinforcing washer 530 is attached to the surface of the vertical lug plate 510 and coincides with the central axis of the pin hole.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
