Abstract
An assembled tower foundation vertical connection bolt anchorage structure comprises three types of vertical bolt lower end anchorage structures for a fixed tower crane and an assembled foundation and a connecting-positioning structure for vertical bolt upper ends and a tower crane bottom frame. Under the condition that vertical connecting bolts and a concrete foundation are combined and decomposed, adjustable and selectable longitudinal distances of vertical connecting bolts can be decreased, the assembly application range of the vertical connecting bolts is widened, meanwhile the hidden danger that nuts at the lower ends of the vertical connecting bolts loosen and drop is eliminated, the number of horizontal pipelines is decreased, accordingly the production and usage cost of the assembled tower foundation is reduced, and technical conditions are provided for industrialization of the assembled tower foundation.
Description
Technical field the present invention relates to the vertical connection construction that the cycle moves the concrete basis of the fixed base tower crane using or fix use and the underframe of top plant equipment.
Background technology is current, cycle in building, electric power, oil, information, Di Kuang, military each field move use as built fixed tower machine, wind-driven generator, oil production machine, signal pylon, rig, the tower mast-type mechanical equipment bases such as heavy ground-based radar, mostly adopt integral cast-in-situ concrete basis, its obvious drawback is, resource utilization is extremely low, long construction period, and cold district fabrication cycle is longer, can not reuse, cause ample resources to waste and environment pollution simultaneously.Existing concrete prefabricated parts assembling tower crane base comes out in recent years, opens foundation for tower crane assembling, reuses, the light-weighted direction and way-out of foundation concrete prefabricated units.But reuse for tower machine assembling type base and the large Technological Economy target of lightweight two, the waste that the combining form on basis fixedly causes by tower machine underframe restricts of existence foundation structure design and the narrow situation of adaptive surface; Prior art is to bearing tilting moment and the less plant equipment of vertical force, especially the fixed tower crane having underframe of China's tower crane recoverable amount more than 80% is accounted for, more be badly in need of solving technically the vertical connection construction of the same model tower machine underframe because of domestic each manufacturer production and the assembling type base of a kind of model of the different formation in basic vertical connection construction plan-position, cannot be connected from the vertical connection construction of the different underframe of the same model tower machine of several producer, that is the versatility on basis and applicability problem.Although more existing non-onces build displacement and diameter, a length conversion difficult problem that dead vertical positioning connection structure of fang bolt solves stone bolt, but all to some extent damage is caused to the cross section of concrete grade beam, simultaneously, the perpendicular bolt duct of presetting in concrete grade beam because of perpendicular bolt and the conditionality of structure space position of horizontal pipe, make the position in the perpendicular bolt duct of presetting can not the very near anchorage point of the distance along underframe longitudinal direction that requires of several tower of simultaneous adaptation machine underframe.The industrialization of concrete prefabricated parts assembling tower crane base facts have proved, this is that the tower machine assembling type base that affects that must break through accelerates to realize the technical bottleneck problem of industrialization.
Summary of the invention object of the present invention and task are under the prerequisite not damaging concrete grade beam, a kind of vertical connection request that can meet tower machine underframe and concrete basis is provided, at several vertical tie points of setting, stone bolt position can be located arbitrarily, in the restriction of the stone bolt position that it laterally makes the width of tower machine underframe be not fixed, the anticreep that there is nut be located in the horizontal pipe of the lower end, perpendicular bolt duct of perpendicular bolt moves back function, the diameter of stone bolt, length also can adjust by different detailing requiments, and the tower machine underframe adapting to different manufacturers and basic vertical connection construction are connected locating structure along the one of the nearer requirement of underframe fore-and-aft distance is vertical.Thus eliminate due to the tower mechanical equipment of the same service behaviour rank of each manufacturer production different underframe and from cannot be general between the concrete different vertical connection construction in basis and the concrete basis of having shaped of factorial praluction drawback, create conditions for accelerating to realize the standardization of foundation for tower crane, factorial praluction and reduction use cost.
