Problems solved by technology
However, for the two technical and economic goals of repeated use and light weight of the combined foundation of tower-mast mechanical equipment, there are wastes and narrow adaptability caused by the fixed combination form caused by the design of the basic structure being restricted by the cross beam of the upper mechanical equipment chassis; prior art For mechanical equipment with small overturning moment and vertical force, especially fixed construction tower cranes with fixed underframe cross beams, which account for more than 80% of the total number of construction tower cranes in China, it is even more urgent to solve the technical problems of domestic manufacturers. The different structural dimensions of the underframe cross beams of tower cranes of the same type lead to different vertical connection structures with the foundation. The vertical connection structure of a type of combined foundation cannot be compared with the underframe cross beams of tower cranes of the same type from several manufacturers. Fixed connection, that is, the basic generality problem
Although some existing non-one-time fixed anchor bolt vertical positioning connection structures solve the problems of anchor bolt displacement and diameter and length transformation, they all cause damage to the cross-section of the concrete foundation beam to varying degrees and become a foundation structure. a safety hazard

Embodiment Construction
[0019] figure 1 , 2 , 3, 4, 5, and 6 describe the structural form of the concrete foundation beam 1 of the mast-type mechanical equipment and the underframe cross beam 16 of the upper mechanical equipment—the structural form and coordination of the lower vertical positioning connection structure of the anchor bolts 2 relation.
[0020] The lower part of the anchor bolt 2 is vertically arranged on the symmetrical two sides of the concrete foundation beam 1 according to the setting section of the anchor bolt 2 including the set position of the anchor bolt 2 of multiple sets of tower cranes along the axial direction of the concrete foundation beam 1. The part of the positioning connection structure combined with the concrete foundation beam 1; the lower end of the anchor bolt 2 passes vertically downward through the horizontal rectangular groove 28 and the lower end of the longitudinal groove main rib plate No. 2 No. 3, and the longitudinal groove main rib plate No. 1 No. 4 Aft...

Vertical connection construction of tower mast type mechanical equipment underframe cross beam is suitable for vertical positioning connection of underframe cross beam structure of tower mast type mechanical equipment and base concrete beam, and can make that position of a lower margin bolt is not restricted by a concrete along transverse and longitudinal direction of a base beam, and diameter and length of the lower margin bolt can be changed according to concrete requirement, thereby realizing standard and serious vertical connection with wide applicability of prefabricated concrete base and tower mast type mechanical equipment using the underframe cross beam with different structures as base under condition of not weakening concrete base beam section and guaranteeing base intensity and integrity.
Description
technical field [0001] The invention relates to the vertical positioning and connection structure of the foundation beam and the upper mechanical equipment of the concrete foundation of the mast-type mechanical equipment used periodically or fixedly. 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, and large land-based radars. Structural foundations mostly 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, the production period is longer in cold regions, the construction is difficult in arid regions, and it cannot be reused. At the same time, it causes a lot of waste of resources and environmental pollution. . In recent years, the cross-sh...
