SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: the assembled combined tower crane foundation is free of cast-in-place construction, high in use efficiency, low in cost and free of environmental pollution, and can be recycled repeatedly.
In order to solve the technical problem, the utility model discloses a following technical scheme:
an assembly combined type tower crane foundation comprises a cross-shaped beam support, wherein four corners of the beam support are respectively provided with a supporting leg, and the beam support is in direct contact with the ground through the supporting legs; the tower crane base mounting structure is characterized in that a counterweight body is loaded on the beam support, a mounting hole which penetrates through the counterweight body from top to bottom is formed in the middle position of the counterweight body so as to form a mounting area for the tower crane base to be mounted on the beam support, a connecting plate which is connected with the tower crane base is arranged in the mounting area of the counterweight body on the beam support, and the connecting plate is fixedly connected with the beam support.

Through the combination type assembly of the beam support and the counterweight bodies, the counterweight bodies are distributed in the circumferential direction of the tower crane, so that sufficient anti-overturning capacity is provided for the tower crane for balancing the tower crane on the beam support, and the phenomenon of overturning cannot occur in the working process of the follow-up tower crane. Therefore, through the tower crane foundation, cast-in-place construction is not needed, the construction period is greatly saved, and the counterweight body of the precast concrete block and the beam support can be disassembled, so that repeated use can be realized, and the tower crane foundation has the advantages of low cost and no pollution to the environment.
Specifically, when in actual use, the connecting plate is usually welded or bolted on the beam support and is located the mounting region of the counterweight body, and because the tower crane base is divided into bolted connection and round pin hub connection mode, consequently the connecting plate also divide into screw connecting rod and pin-hole connecting plate, specifically decides according to tower crane base model. When the counterweight body is arranged on the cross beam support, the counterweight body with proper weight can be selected according to different types of the tower cranes to meet the anti-overturning requirement of the tower cranes.
As optimization, each supporting leg comprises a supporting flat plate and an adjusting screw rod for adjusting the levelness of the beam support, and the beam support is in contact with the ground through the supporting flat plate; the beam support is provided with a vertical screw hole at a position corresponding to the adjusting screw rod, the rod part of the adjusting screw rod is in threaded fit with the screw hole of the beam support, and the head part of the adjusting screw rod is in contact with the upper surface of the supporting flat plate.
