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
The present invention relates to a kind of civil engineering Equipment Foundations structure.
Background technology
In the engineering design of some metallurgy industries, civil Engineering Design personnel often bear some large-scale grooves, the design work of Equipment Foundations such as jar, the top absolute altitude of these Equipment Foundations hundreds of millimeter often only above ground level, but because top equipment volume and weight are very big, cause these Equipment Foundations volumes also to become very big, and Equipment Foundations are formed by concreting, in design in the past, often simply these Equipment Foundations are made entity, so not only need excavation pit in large area, also need simultaneously a large amount of concrete, going out the terrain heat of hydration when building concrete in mass can make concrete produce the crack again, consequently both cause waste of material, engineering safety is reduced, be prone to accident resulting from poor quality of projects.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of elevated large-sized apparatus foundation structure is provided, easily produces the crack to overcome large tracts of land excavation pit, the concrete that traditional Equipment Foundations exist, both caused waste of material, the problem that engineering safety is reduced.
The present invention constitutes like this: it comprises the power of holding (6), go up the construction reinforced concrete frame in the underground power of holding (6), built on stilts district (5) is arranged in the middle of reinforced concrete frame, and this makes somebody a mere figurehead district's former geology tissue for not needing to excavate, or former geology is organized smooth slightly getting final product.
Reinforced concrete frame comprises reinforced concrete slab (1), Vierendeel girder (2), underground type frame column (3), middle girder members such as (4), and Vierendeel girder (2), middle girder (4), reinforced concrete slab (1) are supported by underground type frame column (3).
Post reinforced concrete base base (7) can be built in the bottom of underground type frame column (3).Post reinforced concrete base base (7) strengthens the supporting capacity of elevated large-sized apparatus foundation structure, and this is more favourable for large equipment.
Adopt the overhead type Equipment Foundations structure of above technical scheme design, only need place, patten location is carried out excavation of foundation pit, foundation structure is seated on the bearing stratum frame column of constructing again, go out ground after-pouring Vierendeel girder, middle girder and reinforced concrete slab, so promptly finished the construction of Equipment Foundations.
The invention has the beneficial effects as follows: the concrete amount that significantly reduces large equipment base, reduce the earthwork excavated volume of foundation ditch, the heat of hydration that produces when reducing casting of concrete in mass simultaneously, avoid occurring distress in concrete, thereby reduce engineering risk and difficulty of construction, reduce the incidence of accident resulting from poor quality of projects.

The specific embodiment
Embodiments of the invention: the following rectangular apparatus basis that we make somebody a mere figurehead design with an employing is an example, and this construction sequence of the present invention is described, certainly, this invention is not limited to the rectangular apparatus basis, and circular even special-shaped Equipment Foundations all can adopt this structure.
The first, the weight and the stressed position of the support on Equipment Foundations thereof of calculating top equipment;
The second, Vierendeel girder 2, middle girder 4, reinforced concrete slab 1 are arranged in the position of reasonable Arrangement underground type frame column 3 and post reinforced concrete base base 7, and the equipment of pressing power transmission position on the basis on underground type frame column 3;
The 3rd, to the beam of above-mentioned formation, plate, cylinder system designs and calculates by reinforced concrete frame structure;
During construction, the excavation of foundation pit of fixing a point in the position that is furnished with post, basis seat on bearing stratum, construct successively then beam, plate; Does not excavate in built on stilts district 6 in the reinforced concrete frame the inside, only need carry out simple smooth getting final product, and can save a large amount of bricklaying workloads like this.
By above-mentioned steps, can finish elevated large-sized apparatus Base Design and construction.
