Description

Technical Field

[0001] This utility model relates to the field of base station tower construction technology, and in particular to a prefabricated foundation for a base station tower. Background Technology

[0002] With the rapid development of mobile communication technology, the demand for base station towers is increasing rapidly. Base station operation requires a stable foundation to prevent overturning. Currently, most existing base station tower foundations are constructed by excavating the soil and then pouring an independent foundation. This method requires a long curing time, affecting the construction cycle and increasing costs. Summary of the Invention

[0003] To address the issue of the long curing time required for existing independent foundations of base station towers, this invention proposes a prefabricated foundation for base station towers. This foundation features a fixed connection between a detachable first prefabricated module and a second prefabricated module. Furthermore, the first and second prefabricated modules, the first counterweight, the second counterweight, and the third counterweight are all prefabricated, facilitating easy assembly and disassembly, saving installation time, and thus meeting the need for rapid construction of base station towers.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A prefabricated foundation for a base station tower includes a first prefabricated module and a second prefabricated module. The second prefabricated module is fixedly mounted on the first prefabricated module. A first counterweight and anchor bolts are fixedly mounted on the second prefabricated module. A second counterweight and a third counterweight are fixed on both sides of the first prefabricated module. The first prefabricated module includes multiple detachably connected first modules, and the second prefabricated module includes multiple detachably connected second modules.

[0006] Furthermore, multiple first modules are fixedly connected by bolts, enabling the first prefabricated module to be detachable.

[0007] Furthermore, multiple second modules are fixedly connected by bolts, enabling the second prefabricated module to be detachable.

[0008] Furthermore, the first prefabricated module is provided with a first embedded bolt, and the second prefabricated module has a first opening for the first embedded bolt to pass through. The first embedded bolt passes through the first opening and is fixedly connected to the first counterweight. The first prefabricated module, the second prefabricated module, and the first counterweight are connected into a whole.

[0009] Further, a first groove body with a "convex" - shaped longitudinal section is formed on the first prefabricated module. A third prefabricated module is placed in the first groove body. The lower part of the third prefabricated module matches the first groove body. The part of the third prefabricated module extending out of the first groove body is an extension part. The lower side surface of the extension part covers the opening of the first groove body. A second groove body matching the extension part is formed on one side of the second prefabricated module close to the extension part.

[0010] Further, the second prefabricated module and the third prefabricated module are fixedly connected by bolts. Through the mutually - cooperating first groove body, third prefabricated module and second groove body, after the bolts fix the second prefabricated module and the third prefabricated module, the fixation of the first prefabricated module and the second prefabricated module is achieved.

[0011] Further, second embedded bolts are provided in the second prefabricated module. The first counterweight is fixedly connected to the second embedded bolts.

[0012] Further, third embedded bolts are provided on both sides of the first prefabricated module. The second counterweight and the third counterweight are both fixedly connected to the first prefabricated module through the third embedded bolts.

[0013] Further, third counterweights are provided on both sides of the second counterweight. A reasonably designed counterweight can effectively increase the stability of the base station tower on the foundation.

[0014] Further, lifting rings are provided on the second counterweights on both sides of the first prefabricated module, and lifting rings are also provided on the first counterweight. This is convenient for subsequent lifting and installation.

[0015] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0016] 1. The second counterweights and the third counterweights on both sides of the first prefabricated module of the present utility model form a platform and are both fixedly connected by third embedded bolts. The first prefabricated module, the second prefabricated module and the first counterweight are fixed together by the first embedded bolts of the prefabricated module, making all components form a whole, constituting a firm foundation. At the same time, the bolt connection enables disassembly. The multiple first modules in the first prefabricated module and the multiple second modules in the second prefabricated module are both detachable by bolts, which is convenient for disassembly and assembly and saves the construction time of the base station tower.

[0017] 2. In the present utility model, a third prefabricated module is placed in the first groove body formed in the first prefabricated module. A second groove body matching the third prefabricated module is formed on the second prefabricated module to place the second prefabricated module flat on the first prefabricated module. At this time, the second prefabricated module and the third prefabricated module are connected and fixed by bolts, achieving the connection and fixation of the first prefabricated module and the second prefabricated module, and increasing the stability of the foundation structure.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this embodiment provides a prefabricated foundation for a base station tower, including a first prefabricated module 1 and a second prefabricated module 2. The second prefabricated module 2 is fixedly mounted on the first prefabricated module 1. The first prefabricated module 1 contains a first embedded bolt (not shown in the figure), and the second prefabricated module 2 has a first opening for the first embedded bolt to pass through (see reference). Figure 4 The first pre-embedded bolt passes through the first opening and is fixedly connected to the first counterweight 3.

[0028] Furthermore, a first counterweight 3 and an anchor bolt 4 are fixedly mounted on the second prefabricated module 2, and a second counterweight 5 and a third counterweight 6 are fixed on both sides of the first prefabricated module 1; in this embodiment, a third pre-embedded bolt 11 is provided on both sides of the first prefabricated module 1 (see reference). Figure 2The second counterweight 5 and the third counterweight 6 are both fixedly connected to the first prefabricated module 1 by the third pre-embedded bolt 11; the second counterweight 5 is provided with the third counterweight 6 on both sides.

[0029] For towers requiring counterweight foundations, under the corresponding regional wind pressure, based on the calculated overturning moment of the tower and the geological survey report of the installation location, design a reasonable quantity and size of the first counterweight block 3, the second counterweight block 5, and the third counterweight block 6 to ensure that the overall foundation meets the tower's anti-overturning requirements.

[0030] Furthermore, the first prefabricated module 1 includes four detachably connected first modules; the second prefabricated module 2 includes four detachably connected second modules. The multiple first modules are fixedly connected by bolts, enabling the detachability of the first prefabricated module 1. The multiple second modules are fixedly connected by bolts, enabling the detachability of the second prefabricated module 2.

[0031] refer to Figure 5 Each of the four first modules or four second modules is fixedly connected by four high-strength bolts extending from both ends of the module and screwed with nuts. At the same time, in order to avoid positional interference, the two bolts in the left and right directions are staggered from the two bolts in the front and back directions.

[0032] In this embodiment, in order to facilitate subsequent lifting and installation, lifting rings 10 are provided on the second counterweights 5 on both sides of the first prefabricated module 1, and lifting rings 10 are also provided on the first counterweight 3.

[0033] In this embodiment, the first prefabricated module 1, the second prefabricated module 2, the first counterweight 3, the second counterweight 5, and the third counterweight 6 are all prefabricated structures, which eliminates the previous method of on-site pouring of foundations and greatly speeds up the construction cycle of base station foundations.

[0034] In use, the four first modules and the second module are spliced ​​together and then fixed together with four bolts to form a complete first prefabricated module 1 and a second prefabricated module 2. At this time, the second prefabricated module 2 is placed on the upper side of the first prefabricated module 1. The first pre-embedded bolt in the first prefabricated module 1 passes through the first opening in the second prefabricated module 2 and is fixedly connected to the first counterweight block 3. Then, the second counterweight block 5 and the third counterweight block 6 are connected to the third pre-embedded bolts 11 on both sides of the first prefabricated module 1 to form a complete prefabricated foundation.

[0035] Example 2

[0036] like Figures 3-6As shown, the same parts as in the embodiment will not be described again. The differences are as follows: a first groove 7 with a "convex" cross-section is formed on the first prefabricated module 1. A third prefabricated module 8 is placed in the first groove 7. The third prefabricated module 8 has a "I"-shaped cross-section. The lower part of the third prefabricated module 8 matches the first groove 7. The part of the third prefabricated module 8 extending out of the first groove 7 is an extension part. The lower side surface of the extension part covers the opening of the first groove 7. After the four first modules are connected by bolts, the third prefabricated module 8 is clamped in the first groove 7, and the connection is firm. A second groove 9 matching the extension part is formed on one side of the second prefabricated module 2 close to the extension part, so that the second prefabricated module 2 can be placed flat on the first prefabricated module 1.

[0037] The second prefabricated module 2 and the third prefabricated module 8 are fixedly connected by bolts. At this time, the fixed connection is also achieved by screwing nuts at both ends of 4 high-strength bolts protruding from both ends of the module. Refer to Figure 6 , from left to right, the bolts pass through the second module, the third prefabricated module 8 and the second module in sequence, and nuts are screwed at both ends to achieve fixation, so as to achieve the fixed connection between the first prefabricated module 1 and the second prefabricated module 2.

[0038] Among them, second embedded bolts are provided in the second prefabricated module 2, and the first counterweight 3 is fixedly connected to the second embedded bolts.

[0039] During use, first, the four first modules and the third prefabricated module 8 are spliced together, and then the first prefabricated module 1 is fixed together by four bolts. At this time, the first prefabricated module 1 and the third prefabricated module 8 are clamped. Then, the second counterweight 5 and the third counterweight 6 are connected to the third embedded bolts 11 on both sides of the first prefabricated module 1 to form a flat lower foundation. Then, the four second modules are spliced into one body and placed on the upper side surface of the first prefabricated module 1. At this time, the third prefabricated module 8 enters the second groove 9 of the second prefabricated module 2, and then the first prefabricated module 1 and the third prefabricated module 8 are fixed together by four bolts. Then, the first counterweight 3 is connected and fixed by the second embedded bolts embedded in the second prefabricated module 2, so as to complete the construction of the prefabricated foundation.
