Elevated large-sized apparatus foundation structure

Abstract

The invention discloses a large-scale overhead equipment foundation, wherein, a reinforced concrete frame is built on an underground bearing layer (6); an overhead region (5) is arranged in the middle of the reinforced concrete frame which comprises elements such as a reinforced concrete plate (1), a frame beam (2), an underground frame column (3), an intermediate beam (4) and so on; and the frame beam (2), the intermediate beam (4) and the reinforced concrete plate (1) are supported by the underground frame column (3). As for a foundation of oversized equipment, a reinforced concrete foundation footing (7) is built on the lower part of the underground frame column (3). The large-scale overhead equipment foundation can greatly reduce the concrete amount of large-scale equipment, reduce the earthwork excavated volume of a foundation pit, simultaneously reduce the hydration heat generated under the condition of bulk concrete placement, and avoid generation of concrete cracks, consequently reducing the engineering risk and the construction difficulty and reducing the incidence rate of engineering qualitative accidents.

Description

Technical field [0001] The invention relates to a basic structure of civil engineering equipment. Background technique [0002] In the engineering design of some metallurgical industries, civil designers often undertake the design work of some large tanks, tanks and other equipment foundations. The top elevation of these equipment foundations is often only a few hundred millimeters higher than the ground, but due to the large volume and weight of the upper equipment As a result, the volume of these equipment foundations has also become very large, and the equipment foundations are made of concrete. In the past design, these equipment foundations are often simply made into entities, which not only requires a large area of ​​foundation excavation At the same time, a large amount of concrete is required for pits. The heat of hydration when pouring large volumes of concrete will also cause cracks in the concrete. As a result, it not only wastes materials, but also reduces engineering...
