Embodiment 1

[0053] Such as Figure 1-4 As shown, the embodiment of the present application discloses a pre-leveled tower foundation, including:

[0054] Reinforcement cage 1, the reinforcement cage 1 is bound by a plurality of steel bars. When binding, it is necessary to ensure that the reinforcement cage 1 has sufficient stability and has a working space inside;

[0055] A plurality of support bars 2 are installed on the reinforcement cage 1 at intervals, and the upper surfaces of the support bars 2 are at the same level, and the support bars 2 are used to support the subsequent fixed mold;

[0056] The fixed form 3 is assembled on the upper side of the steel cage, and the lower surface of the fixed form 3 is in contact with the upper surface of the supporting steel bar 2. The fixed form 8 in the embodiment of the present application is convenient for the subsequent assembly of the tower crane.

[0057] A plurality of adjusting bolts 4 are installed on the reinforcement cage 1 at interv...

Abstract

The invention discloses a pre-levelled tower footing foundation. The foundation comprises a reinforcement cage, a plurality of supporting steel bars, a fixed form, a plurality of adjusting bolts, a plurality of leveling steel plates, a plurality of foundation bolts and a concrete layer; the supporting steel bars are arranged on the steel reinforcement cage at intervals, and the upper surfaces of the supporting steel bars are located on the same horizontal plane; the fixed form is assembled above the reinforcement cage, and the lower surface of the fixed form is in contact with the upper surfaces of the supporting steel bars; the adjusting bolts are arranged on the reinforcement cage at intervals; the leveling steel plates are arranged at the tops of the adjusting bolts at intervals, the leveling steel plates are located below the fixed form, and the upper surfaces of the leveling steel plates are located on the same horizontal plane; the foundation bolts sequentially penetrate through the leveling steel plates and the fixed form from bottom to top; and the concrete layer is poured on the reinforcement cage, and the upper surface of the concrete layer is flush with the upper surfaces of the leveling steel plates. The invention further discloses a leveling construction method for the supporting surface. The technical problems that in the prior art, follow-up leveling of a tower footing is tedious, and the stability of the supporting surface is affected are solved.

Description

technical field [0001] The invention relates to the technical field of tower crane auxiliary accessories, in particular to a pre-leveled tower foundation and a leveling construction method thereof. Background technique [0002] In recent years, with the continuous development of my country's construction industry, more and more high-rise group buildings have been built in large and medium-sized cities. Considering factors such as reducing the secondary handling of building materials and the transportation distance in the field, tower cranes are often erected next to the main buildings. Nowadays, the conventional tower crane foundation is generally made of concrete, and then connected to the connection end of the tower crane foundation section through the anchor bolts embedded in the concrete. For leveling, it is usually necessary to construct a fine stone leveling layer to ensure that the upper surface of the concrete is level, so that Time-consuming and labor-intensive, the e...
