Description

Technical Field

[0001] This utility model relates to the field of communication tower base technology, and in particular to a communication tower base and a communication tower thereof. Background Technology

[0002] Communication towers, also called signal transmission towers or signal towers, primarily function to support signal transmission and provide support for signal transmitting antennas. Communication towers mainly include steel structure towers and columnar communication towers. Steel structure towers are constructed from steel structures, while columnar communication towers have a cylindrical main body.

[0003] In existing technologies, the bottom of a columnar communication tower is fixed by concrete pouring, and the tower body near the bottom flange is bolted to the concrete foundation. This type of tower base structure has limited stability and support for the tower body and can only be used for small signal towers. When the communication tower is tall and large, the existing tower base is insufficient to support the stability of the tower body. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a communication tower base and a communication tower thereof, wherein the communication tower base has high load-bearing capacity and good stability, so that the communication tower has good stability, is not easy to tilt or collapse, and has a long service life.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A communication tower base includes a base flange, a multi-step column section, and a transition section located between the base flange and the multi-step column section. The base flange is located at the top of the tower base and is used for fixed connection to the tower body.

[0007] The multi-tiered column section comprises multiple stacked columns, with the cross-sectional area of ​​the columns gradually decreasing from top to bottom. The multi-tiered column section has an internal cavity.

[0008] Let the uppermost column be the first layer column, the bottommost column be the last layer column, and the multiple columns between the first layer column and the last layer column be the middle layer column. The last layer column includes multiple support legs, which are evenly distributed around the center of the tower base. The interval between two adjacent support legs is a casting groove. Multiple spaced casting guide holes are opened on the outer peripheral side of the middle layer column, and the casting guide holes are connected to the inner cavity.

[0009] Preferably, the first layer of column has a plurality of spaced connector mounting holes on its end face, and the plurality of connector mounting holes are distributed in an array around the center of the tower base.

[0010] Preferably, the transition section is configured as a frustum, the small-diameter end of the frustum is connected to the tower base flange, the large-diameter end of the frustum is connected to the multi-step column section, and the outer peripheral surface of the frustum is a concave arc surface.

[0011] Preferably, the mounting hole of the connector is a threaded hole, and a bolt is installed at the thread.

[0012] Preferably, the mounting hole of the connector is set as a light hole, and a steel strand is installed at the light hole.

[0013] Preferably, the casting guide hole is a horizontal hole, and the center line of the casting guide hole is set perpendicular to the center line of the tower base.

[0014] Preferably, the casting guide hole is an oblique hole, and the outer end opening of the casting guide hole is higher than the inner end opening of the casting guide hole.

[0015] A communication tower comprising the aforementioned communication tower base.

[0016] Preferably, the communication tower includes a tower body, the bottom of which is fixedly connected to the tower base. Multiple reinforcing connecting lugs are fixed on the tower body, and each reinforcing connecting lug is connected to a traction rope lock. The other end of the traction rope lock is connected to the ground.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This utility model discloses a communication tower base, comprising a base flange, a multi-step column section, and a transition section between the base flange and the multi-step column section. The base flange is located at the top of the tower base and is used for fixed connection of the tower body. The multi-step column section comprises multiple stacked columns, with the cross-sectional area of ​​the columns gradually decreasing from top to bottom. The surface of the multi-step column section includes the end face and side circumferential face of each step, thereby increasing the contact area between the multi-step column section and the poured concrete, and further increasing the bonding force and frictional resistance between the multi-step column section and the concrete base. This significantly improves the stability of the communication tower base and makes the tower base more firmly fixed, greatly improving the load-bearing capacity of the foundation structure (the tower base and the concrete base together constitute the foundation structure), and overall improving the stability and service life of the communication tower.

[0019] Because the multi-tiered column section has an internal cavity, the final column includes multiple support legs, which are evenly distributed around the center of the tower base. The interval between two adjacent support legs is a pouring groove. The outer periphery of the middle column has multiple spaced pouring guide holes that connect to the internal cavity. After the concrete is poured, the solidified concrete at the pouring groove alternates with the support legs. The support legs are equivalent to upper toothed discs, and the solidified concrete at the pouring grooves is equivalent to lower toothed discs. This toothed disc structure with alternating upper and lower teeth not only prevents the communication tower from rotating under external forces but also ensures a firm bond between the communication tower base and the concrete foundation, improving the stability of the communication tower base and the communication tower itself. During concrete pouring, the pouring guide hole not only facilitates the guidance of concrete from the outside of the middle layer column into the inner cavity, but also, after the concrete solidifies, the solid concrete within the pouring guide hole simulates the "root gripping the ground" effect, connecting the concrete part in the inner cavity with the concrete part outside the multi-step column body, further improving the bonding force between the communication tower base and the concrete base, making the communication tower base more firmly fixed and improving the stability of the communication tower base.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1:

[0034] like Figures 1 to 4 As shown, the communication tower base of this utility model includes a tower base flange 1, a multi-step column section, and a transition section 2 located between the tower base flange 1 and the multi-step column section. The tower base flange 1 is located at the top of the tower base and is used to fix and connect the tower body 5. The multi-step column section 3 includes multiple stacked columns, with the cross-sectional area of ​​the columns gradually decreasing from top to bottom. The multi-step column section 3 has an inner cavity 30. In this embodiment, the multi-step column section 3 preferably includes three stacked columns, with the uppermost column being designated as the first column. The first layer column 31, the bottommost column is the last layer column 33, and the multiple columns between the first layer column 31 and the last layer column 33 are the middle layer columns 32. The last layer column 33 includes multiple support legs 331, which are evenly distributed around the center of the tower base. The interval between two adjacent support legs 331 is a casting groove 332. Multiple casting guide through holes 321 are provided on the outer peripheral side of the middle layer column 32, and the casting guide through holes 321 are connected to the inner cavity 30.

[0035] The stepped column is preferably a cylinder, but it can also be a cube or a polygonal column.

[0036] The surface of the multi-step column 3 includes the end face and side circumferential face of each step, thereby increasing the contact area between the multi-step column 3 and the poured concrete, and further increasing the frictional resistance between the multi-step column and the concrete base 4, which significantly improves the bearing capacity and stability of the communication tower base, and thus makes the communication tower base more firmly fixed.

[0037] Multiple support legs 331 are evenly distributed around the center of the tower base, with the interval between two adjacent support legs 331 forming a pouring groove 332. After the concrete is poured, the solidified concrete located in the pouring groove 332 alternates with the support legs 331. The support legs 331 are equivalent to the upper toothed disc, and the solidified concrete located in the pouring groove 332 is equivalent to the lower toothed disc. This toothed disc structure with alternating upper and lower teeth not only prevents the communication tower from rotating under the influence of external forces, but also makes the communication tower base firmly connected to the concrete base 4, improving the stability of the communication tower base and the communication tower itself.

[0038] Of course, the multi-tiered column section 3 can also include four, five, or even more stacked columns, depending on the specifications of the tower. When four stacked columns are set, the two middle columns are the middle layer columns 32. Casting guide holes 321 can be set on the peripheral surfaces of both middle layer columns 32, or casting guide holes 321 can be set on one of them.

[0039] During concrete pouring, the pouring guide hole 321 not only facilitates the guidance of concrete from outside the middle layer column 32 into the inner cavity 30, but also, after the concrete solidifies, the solid concrete within the pouring guide hole 321 acts like "tree roots gripping the ground," connecting the concrete portion inside the inner cavity 30 with the concrete portion outside the multi-tiered column portion 3. This further enhances the bonding force between the communication tower base and the concrete base 4, making the communication tower base more firmly fixed and improving its stability.

[0040] In this embodiment, as Figure 4 As shown, the casting guide hole 321 is a horizontal hole, and its centerline is perpendicular to the centerline of the tower base. Horizontal holes facilitate machining. Of course, the casting guide hole 321 can be round, square, or other shapes.

[0041] In some embodiments, such as Figure 2 and Figure 3 As shown, preferably, a plurality of spaced-apart connector mounting holes 311 are provided on the end face of the first-layer column 31, and the plurality of connector mounting holes 311 are distributed in an array around the center of the tower base. When concrete is poured, the connectors are installed at the connector mounting holes 311, which not only increases the contact area with the concrete, but also makes the concrete base 4 more firmly fixed.

[0042] The transition section 2 is configured as a frustum. The small-diameter end of the frustum is connected to the tower base flange section 1, and the large-diameter end of the frustum is connected to the multi-step column section 3. The outer circumferential surface of the frustum is a concave arc-shaped surface. This concave arc-shaped frustum reduces stress concentration on the one hand, and on the other hand, the interface between the concave arc-shaped surface and the concrete base 4 is larger, resulting in a stronger connection.

[0043] like Figure 6 and Figure 10 As shown, the communication tower includes the aforementioned tower base. The tower includes a tower body 5, the bottom of which is fixedly connected to the tower base, typically via flanges and bolts / nuts. Reinforcing ribs connect the flanges and the tower. Multiple reinforcing lugs 51 are fixed to the tower body 5, each connected to a traction rope lock 6. The other end of the traction rope lock 6 is connected to the ground. The traction rope lock 6 typically pulls the tower body 5 in three directions. By properly configuring the traction ropes, the required strength of the tower body can be reduced, and the tower can be stabilized to prevent it from tipping over.

[0044] In summary, the communication tower base of this invention is firmly integrated with the concrete base 4, which greatly improves the stability of the communication tower and enables it to effectively resist extreme weather conditions.

[0045] Example 2:

[0046] The difference between Example 2 and Example 1 is that:

[0047] like Figure 5 As shown, the pouring guide hole 321 is an inclined hole, with the outer end of the pouring guide hole 321 being higher than the inner end of the pouring guide hole 321. Compared to a transverse hole, the inclined hole can guide the concrete from the outside of the middle layer column 32 to the inner cavity 30 more quickly during pouring.

[0048] Example 3:

[0049] like Figure 7 As shown, the mounting hole 311 of the connector is a threaded hole, and a bolt 7 is installed at the thread. After the concrete is poured, a concrete base 4 is formed, and the bolt extends out of the concrete base 4 and is tightened with a nut. The bolt 7 makes the connection between the communication tower base and the concrete base 4 more secure and robust.

[0050] Example 4:

[0051] The difference between Example 4 and Example 3 is that:

[0052] like Figure 8 As shown, the mounting hole 311 of the connector is set as a light hole, and a steel strand 8 is installed at the light hole. After the concrete is poured, a concrete base 4 is formed. The steel strand 8 increases the bonding area between the communication tower base and the poured concrete, making the connection between the communication tower base and the concrete base 4 more solid and the connection stronger.

[0053] Example 5:

[0054] The difference between Example 5 and Example 4 is that:

[0055] like Figure 9As shown, the steel strand 8 is relatively long, extending both above and below the connector mounting hole 311, with its top end protruding from the top surface of the concrete base 4. This not only ensures a tight bond between the communication tower base and the concrete base 4, improving the overall load-bearing capacity of the tower foundation, but also extends the service life of the tower foundation.

[0056] In summary, the communication tower base of this invention has high load-bearing capacity and good stability, making the communication tower less prone to tilting and collapse, and extending its service life.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Enlarging the dimensions of the communication tower base, slightly altering the number and position of the holes on the tower base flange, setting the transition section as a frustum-shaped square pyramid, and setting the multi-step column section as a stacked cuboid can also serve as an installation base for steel structure towers. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
