Combined foundation of backstay type machinery apparatus

Abstract

The invention relates to a mast integrated base of mechanical device, providing a square cross beam and slab structure combined by prefabricated elements, and solid bulk material with certain volume weight to apply periodically movement. It comprises a horizontal integrated method formed by horizontal connection system whose upper and lower spaces are crossed without bond stress, taper positioning structure and anti-shear anti-displacement structure; the vertical connection structure and the transition connection structures in same property standard can realize the standardization and seriation of prefabricated mast mechanical device integrated base, with small accommodation area, quick installment, saved resource, and significant economic benefits.

Description

Technical field: [0001] The invention relates to a concrete prefabricated component used in periodical movement or a mast-type mechanical equipment foundation composed of a concrete prefabricated component and other solid bulk materials with a certain bulk density. Background technique: [0002] At present, construction, electric power, petroleum, information, mining, and military fields are periodically mobile, such as construction fixed tower cranes, wind power generators, oil extraction machines, signal towers, drilling machines, large radar and other mast-type mechanical equipment. Most of the foundations use integral cast-in-place concrete foundations. The obvious disadvantages are that the utilization rate of resources is extremely low, the construction period is long, and the production period in cold regions is longer, and they cannot be reused. At the same time, they cause a lot of waste of resources and environmental pollution. In recent years, there have been towe...

Problems solved by technology

[0002] At present, construction, electric power, petroleum, information, mining, and military fields are periodically mobile, such as construction fixed tower cranes, wind power generators, oil extraction machines, signal towers, drilling machines, large radar and other mast-type mechanical equipment. Most of the foundations use integral cast-in-place concrete foundations. The obvious disadvantages are that the utilization rate of resources is extremely low, the construction period is long, and the production period in cold regions is longer, which cannot be reused, and at the same time causes a lot of resource waste and environmental pollution.

In recent years, there have been tower crane foundations with cross-type combined concrete prefabricated components. Because the ratio of the force-bearing area of ​​the foundation to the area of ​​the foundation outline is still small, the foundation occupies a large area and the total weight of the components is large. Although some In the method of combining prefabricated foundation components, the post-tensioning unbonded prestressing technology is cited, but for the two technical goals of repeated use and lightweight of the combined tower crane foundation, there is still a small scope of application, and it is only suitable for some overturning Tower cranes with small moment and vertical force, and tower cranes with large overturning moment and vertical force have limitations in terms of safety performance, versatility, economic benefits in use, and further resource saving, which limits the Supporting use for other periodic mobile mast-type mechanical equipment
