Abstract
A vertical positioning connection structure of a stone bolt is applicable to the vertical positioning connection between underframe cross beam structure of mast type mechanical equipment and a basic concrete beam. The position of the stone bolt along transverse direction and longitudinal direction of a base beam is sacred from restriction of a concrete and the diameter and length of the stone bolt is capable of being adjusted and changed according to specific requirements, thus under the condition of not weakening or as little as possible weakening the section of the concrete base beam and guaranteeing base intensity and integrity, the invention realizes standardized and serialized vertical positioning connection structure with wide applicability between different mast type mechanical equipments structured by different underframe cross beam structure from different factories and prefabricateed concrete bases.
Description
Technical field the present invention relates to the cycle and moves and use or the grade beam on fixing backstay type machinery apparatus concrete basis of using and the perpendicular positioning joint construction of top plant equipment.
Background technology is present, the cycle in building, electric power, oil, information, Di Kuang, military each field move use as building fixed tower machine, wind-driven generator, oil production machine, signal pylon, rig, backstay type machinery apparatus bases such as heavy ground-based radar, mostly adopt integral cast-in-situ concrete basis, its obvious drawback is that resource utilization is extremely low, long construction period, and the cold district fabrication cycle is longer, can not reuse, cause ample resources waste and environment pollution simultaneously.Existing in recent years concrete prefabricated parts cross type foundation for tower crane and square type foundation for tower crane come out, and have opened up that the backstay type machinery apparatus base set is box-like, repeated use, the light-weighted direction of basic concrete prefabricated parts and road.But reuse and lightweight two big Technological Economy targets at combined foundation of backstay type machinery apparatus, exist basic constructional design restricted by the plant equipment underframe cross beam and waste and the narrow situation of adaptive surface that combining form fixedly causes; Prior art is to bearing the less plant equipment of tilting moment and vertical force, especially account for the fixed building tower machine that the fixed frame rood beam is arranged of China's building tower machine recoverable amount more than 80%, the physical dimension difference of underframe cross beam of more being badly in need of solving technically the same model tower machine of domestic each manufacturer production causes with the vertical connection construction on the combined type basis of a kind of model of the different formation of basic structure connected vertically and can't fixedly connected with the underframe cross beam of the same model tower machine of several producers, that is the versatility and the broad applicability problem on basis.Though more existing non-onces are built dead vertical positioning connection structure of fang bolt and have been solved the displacement of stone bolt and diameter, a length conversion difficult problem, but all to some extent damage is caused in the cross section of concrete grade beam, become a kind of new hidden danger of basis safety.The industrialization on combined type basis facts have proved that this is the technical bottleneck problem that combined foundation of backstay type machinery apparatus accelerates to realize industrialization that influences that must break through.
Summary of the invention purpose of the present invention and task are under the prerequisite of not damaging the concrete grade beam, provide a kind of and can satisfy the underframe cross beam structure of backstay type machinery apparatus and the perpendicular positioning connection request of concrete grade beam, in the scope of setting, the stone bolt position vertically can be located arbitrarily along the concrete grade beam, laterally make the width of underframe cross beam not be subjected to the restriction of stone bolt position at it, the diameter of stone bolt, length also can be by a kind of perpendicular positioning joint constructions of designing requirement adjustment.Thereby eliminate because drawback that can't be general between the concrete basis of having finalized the design that the different underframe cross beam of same other backstay type machinery apparatus of service behaviour level of each manufacturer production and the perpendicular positioning joint construction different with the concrete grade beam thereof and batch production are produced, for standardization, the batch production production of quickening realization backstay type machinery apparatus basis creates conditions.
