For a three-pipe or four-pipe communication tower, a prefabricated independent foundation is used, and the independent foundation is large in size, heavy in weight and inconvenient to transport. To this end, the patent application No. 201220005049.2 discloses a jointed prefabricated communication tower foundation. The main technical characteristics are as follows: the tower comprises a tower body, the bottom of tower body is provided with a plurality of prefabricated foundatin blocks, and prefabricated foundatin block is provided with the rigid connection board, and the rigid connection board of adjacent prefabricated foundatin block is connected through the round pin axle. Because the prefabricated foundation is buried underground, the rigid connecting plate and the pin shaft are easy to be rusted, and the whole bearing capacity of the prefabricated foundation is influenced.
Disclosure of Invention
The utility model discloses to the technical problem who exists among the prior art, provide a prefabricated basis of communication tower, use a plurality of bases of mutual contact, adopt reasonable shape design and position to distribute, lighten the weight of base when guaranteeing prefabricated basic whole bearing capacity.
The utility model adopts the technical proposal that: the utility model provides a prefabricated basis of communication tower, includes central base and angle base, be equipped with fixed step face on the central base, the angle base be located on the fixed step face, the contact surface of central base and angle base is the inclined plane, fixed step face and angle base correspond the position and are provided with fixed orifices and fixed slot respectively, and the dead lever is located in fixed orifices and the fixed slot, be equipped with the boss on the angle base, be equipped with the metal sheet between boss and angle base, a plurality of buried screw rods stretch into in boss, metal sheet and the angle base, part buried screw rod exposes in the boss.
Preferably, the included angle between the bottom surface of the corner base and the horizontal plane is-10-0 degrees, and the included angle between the side surface of the corner base, which is in contact with the central base, and the horizontal plane is 80-90 degrees.
Preferably, the corner base has a trapezoidal cross-section.
Preferably, the thickness of the central base is 40% -60% of the thickness of the corner base.
Preferably, the boss and the corner base are integrally cast.
Preferably, the fixing rod is made of I-shaped steel.
The working principle is as follows: the integral prefabricated foundation is divided into a central base and an angle base, the thickness of the central base is reduced, the cross section of the angle base is designed into a trapezoid, the bearing capacity is not reduced, the weight is reduced, and transportation is facilitated. The side face with the largest area of the corner base serves as a contact face and is in contact with the side face of the central base, part of the bottom face of the corner base is in contact with the fixed step face, the contact face is designed into inclined faces with different angles according to different bearing weights, so that the inclined faces have the most appropriate stress directions, stress of the corner base can be well transmitted to the central base, the base is stressed integrally, stress balance is guaranteed, and integral bearing capacity is improved. The angle of the bevel depends on the weight of the tower and the position of the embedded screws. The dead lever mainly plays the effect of location, and is less to connection, bearing pressure effect between the base, adopts the I-steel, and convenient for material selection, the cost is lower.
Compared with the prior art, the utility model discloses the beneficial effect who has is: 1. the utility model adopts a multi-base structure, and the single base has lighter weight and is convenient to transport;
2. the utility model adopts the inclined plane contact among the bases, thereby improving the stress condition and the bearing capacity;
3. the utility model has the advantages of low cost, convenient transportation and installation.
