Description

Technical Field

[0001] The utility model relates to the technical field of angle steel tower bases, in particular to an angle steel tower base. Background Art

[0002] Economic development drives urban development, and urban development cannot be separated from the strong guarantee of infrastructure construction, and power infrastructure construction is particularly important among all infrastructure construction, especially the erection of transmission lines. In high-voltage transmission lines, most of them use angle steel towers as power towers. Angle steel towers are a kind of space truss structure composed of angle steel.

[0003] Angle steel towers are generally erected in the wild. The soil conditions in different regions are different. Directly pouring concrete bases in areas with soft soil can easily cause sinking, causing the power tower to tilt, posing a safety hazard. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an angle steel tower base, which solves the problems mentioned in the above background.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model sets a positioning frame to limit the poured cement, and fixes a plurality of anti-sinking plates on the outer wall of the positioning frame. The anti-sinking plates increase the contact surface with the soil, and the anti-sinking plates are designed to be W-shaped to strengthen the grip of the soil. When the base has a sinking problem, the inverted V-shaped grooves at the bottom of the anti-sinking plates and the support plates on both sides share the force points of the base to slow down the sinking of the base. When the angle steel tower tilts, the anti-sinking plates are tilted upward to give the anti-sinking plates a barbed effect, thereby strengthening the resistance with the soil and reducing the possibility of the angle steel tower tilting.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4, including a positioning frame 1. When pouring cement, the cement can be confined inside the positioning frame 1, and through the cooperation of several groups of positioning frames 1, when constructing angle steel towers of different sizes, different numbers of positioning frames 1 can be combined according to the geographical location, while ensuring that the angle steel tower can be stabilized, the waste of materials can be reduced. The anti-sinking plate 2 is fixed to the outer surface of the positioning frame 1 at one end and is inclined upward. The anti-sinking plate 2 is W-shaped as a whole. Since the anti-sinking plate 2 extends to the outside of the positioning frame 1 and is inclined upward, after pouring cement inside the positioning frame 1, soil is buried on the outside of the positioning frame 1 to fix the positioning frame 1 underneath. When the soil covers the anti-sinking plate 2, the position of the positioning frame 1 is limited by the extension of the anti-sinking plate 2. When the base sinks, the bottom of the anti-sinking plate 2 is supported by the soil to share the pressure of the base body and slow down the sinking of the base. When the angle steel tower tilts due to the influence of wind, the soil is pressed on the top of the anti-sinking plate 2, increasing the fixed area of ​​the base in the soil, thereby limiting the movement of the positioning frame 1 through the anti-sinking plate 2 and reducing the possibility of the base tilting; the extension plate 1 3 is fixed to the inner wall of the positioning frame 1; the extension plate 2 4 is arranged inside the positioning frame 1, and the end is fixed to the extension plate 1 3. The position of the positioning frame 1 can be further limited by the extension plate 1 3 and the extension plate 2 4, thereby strengthening the fixation of the base; the through hole 5 is opened on the surface of the extension plate 1 3 and the extension plate 2 4. When pouring cement inside the positioning frame 1, the bottom of the extension plate 1 3 and the extension plate 2 4 may be vacant due to the poor fluidity of the cement. Through the opened through hole 5, the cement can flow to the bottom of the extension plate 1 3 and the extension plate 2 4, thereby improving the comprehensiveness of the cement pouring and making the positioning frame 1 fully contact and fixed with the cement.

[0026] A fixed shaft 6 is fixed below the outer wall of the positioning frame 1, and a connecting rod 7 is sleeved on the surface of the fixed shaft 6. The fixed shaft 6 supports each group of positioning frames 1, and when storing, the fixed shaft 6 can be rotated to one side of the positioning frame 1 so that the fixed shaft 6 is located at the bottom of the extension plate 3, reducing the space occupied by the fixed shaft 6. A limiting plate 8 is provided on the surface of the positioning frame 1 at a position corresponding to the connecting rod 7, and a mounting groove is provided on the end of the surface of the connecting rod 7 away from the fixed shaft 6. The connecting rod 7 can be plugged into the limiting plate 8 by rotation, so that the two groups of positioning frames 1 can be assembled with each other. A positioning hole 9 is provided in the mounting groove of the connecting rod 7, and a mounting hole is provided on the surface of the limiting plate 8 at a position corresponding to the positioning hole 9. A limiting column 10 is installed inside the positioning hole 9. A compression spring 11 is installed between the limit column 10 and the positioning hole 9 to support the limit column 10. When the connecting rod 7 and the limit plate 8 are plugged in, the limit column 10 is pushed by the compression spring 11 to extend into the installation hole opened in the limit plate 8, so that the limit plate 8 can be connected and fixed to the connecting rod 7.

[0027] Working principle: according to the size of the angle steel frame to be built, different numbers of positioning frames 1 are selected for assembly to ensure the depth of the base in the ground. When assembling the positioning frame 1, the fixed shaft 6 is rotated to plug the connecting rod 7 with the limiting plate 8. The connecting rod 7 is connected to another group of limiting plates 8 by plugging the limiting column 10 with the mounting hole of the limiting plate 8. When pouring cement, the empty parts of the two groups of positioning frames 1 are blocked by baffles, and then the interior of the positioning frame 1 is poured. When the cement encounters the extension plate 1 3 or the extension plate 2 4, it can be opened from the surface of the extension plate 1 3. The through hole 5 flows to the bottom of the extension plate 3, thereby continuing to fill the bottom of the extension plate 3, reducing the gap between the cement and the positioning frame 1, strengthening the connection between the positioning frame 1 and the cement, and after the cement is poured again, the extension plate 3 and the extension plate 2 4 are combined with the cement to further strengthen the fixation of the positioning frame 1. After pouring, the outside of the positioning frame 1 is filled with soil and stones to fix the base underground. When the soil is filled, it contacts the surface of the anti-sinking plate 2, thereby strengthening the fixation of the base. When the base sinks or tilts, the anti-sinking plate 2 expands the force surface of the base, which helps to stabilize the base.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
