Abstract
The utility model discloses a large gauge overhead wall-attached type track beam structure of a large-scale walking tower crane. The track beam structure is characterized in that two box-shaped track beams are arranged at the bottom of the tower crane; a plurality of support steel pipes are arranged at the bottom of each box-shaped track beam; and a planar support is arranged between the two adjacent support steel pipes. A support steel pipe is adopted for the support system of a high-altitude attached walking tower crane as a vertical support, and a box-shaped track steel beam is used as a horizontal support, and a flexible combined support of ledgers and steel wire ropes are combined to form a planar support. Two box-shaped track beams at two sides of the tower crane are respectively connected with each other by the a lateral stable support at a closed structural floor, therefore, on the one hand, horizontal loads of the tower crane in multiple directions can be transmitted to the floor structure, and on the other hand, the stability of high-altitude support can be ensured. The large gauge overhead wall-attached type track beam structure of the large-scale walking tower crane has the advantages that the tower crane can operate as easily as walking on firm earth under the condition of larger difference of the floor height, thereby avoiding the connection between large gauges, therefore, the operation is convenient to operate, and certain construction cost can be saved.
Description
Technical field
The utility model device relates to large-tonnage tower crane apparatus field, is specifically related to the built on stilts wall-attached track girder structure of big gauge of large-scale walking tower crane.
Background technology
Large-scale steel structure was installed on the large area concrete multistory frame structure and was used widely in recent years, owing to be subjected to the restriction of conditions such as workyard, mechanical characteristics, construction cost, the facility location mode that the large-scale tower crane walking is constructed on floor is used more and more widely.The constructional feature of each engineering has nothing in common with each other, and the difficulty that walking brings to tower crane differs, and especially for the bigger structure difficult point of the floor discrepancy in elevation, should take certain working measure to guarantee safety, feasibility and the economy of tower crane walking.
Summary of the invention
The purpose of this utility model is to solve the problem that large-scale construction tower crane is walked under the bigger situation of the floor discrepancy in elevation, provides a kind of and can make somebody a mere figurehead wall-attached track girder structure at the big gauge that is subjected to the large-scale walking tower crane under the constructional feature limited case.
In order to realize this purpose, the technical solution of the utility model is as follows: the big gauge of large-scale walking tower crane is maked somebody a mere figurehead wall-attached track girder structure, it is characterized in that this tower crane bottom is provided with two box-shaped track girders, the bottom of every box-shaped track girder is provided with a plurality of supporting steel pipes, is provided with planar support between two adjacent supports steel pipes.Wherein planar support comprises steel rope, and an end of steel rope is connected with the supporting steel pipe upper end, and the other end of steel rope is connected with the supporting steel pipe bottom, and the lower end of steel rope is provided with turnbuckle.The built on stilts wall-attached track girder structure of the big gauge of this large-scale walking tower crane is arranged on the low structure floor by supporting steel pipe, and the outside of two box-shaped track girders is supported with close high structure floor by lateral stability respectively and linked to each other.
High-altitude adhesion type walking tower crane support system adopts supporting steel pipe to support as vertical, and box track girder steel as horizontal support, and is supported the formation planar support in conjunction with the limber hook up of spending blue and steel rope.It is continuous that two box-shaped track girders of tower crane both sides adopt lateral stability to support respectively at close structure floor, the horizontal loading of a plurality of directions of tower crane can be passed on the floor structure on the one hand, guarantees the stability that the high-altitude is supported on the other hand.Advantage of the present invention is a tower crane in that run under the bigger situation of the floor discrepancy in elevation can " as though walking upon flat ground ", avoids the connection between the big gauge, and not only constructing operation is convenient, and can save certain construction cost.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The big gauge of large-scale walking tower crane is maked somebody a mere figurehead wall-attached track girder structure, it is characterized in that this tower crane 1 bottom is provided with two box-shaped track girders 2, and the bottom of every box-shaped track girder 2 is provided with between 3, two adjacent supports steel pipes 3 of a plurality of supporting steel pipes and is provided with planar support.Wherein planar support comprises steel rope 4, and an end of steel rope 4 is connected with supporting steel pipe 3 upper ends, and the other end of steel rope 4 is connected with supporting steel pipe 3 bottoms, and the lower end of steel rope 4 is provided with turnbuckle 7.The built on stilts wall-attached track girder structure of the big gauge of this large-scale walking tower crane is arranged on the low structure floor by supporting steel pipe, and the outside of two box-shaped track girders is supported 5 by lateral stability respectively and linked to each other with close high structure floor 6.
According to an embodiment of the present utility model, in the tower crane walking operation operating mode, adopt 609 steel pipes to support as vertical supporting steel pipe, for the absolute altitude that guarantees each supporting leg of tower crane base can not produce relative relief because of the vertical compressive deformation that supports, adopt jack adjusting place to add the Two bors d's oeuveres channel-section steel at original base and fix.Equally, consider the influence that amount of deflection is used tower crane, adopt 800 * 980 * 40 * 20 box-type sections as the track girder steel, spacing is 14.3 meters between the track, greater than 8 meters standard spans of tower crane.
Because what form between track girder steel and 609 steel pipes is the parallelogram system, is actv. triangle system for satisfying the support system stress system, adopt the strengthening member of turnbuckle and unrestrained wind steel rope in loading process.Way is as follows: top and bottom need burn hanger, in order to connect unrestrained wind steel rope.Wave wind steel rope adopts diameter 24.5mm steel rope, needs to connect (scalable) with 5 tons of turnbuckles, and the two sides steel rope needs tension simultaneously.The steel rope attachment point needs 3 rope clamps, needs 5T to unload first 8 with the hanger point of connection, does not allow direct reeve, splits in case fast mouth is cut.Be steel rope pass through unload first and be connected with the hanger that is located at supporting steel pipe.
Consider that may there be a plurality of directions in the horizontal force that tower crane passes to interim support system, must be connected with the contiguous floors structure, therefore track girder steel and concrete structure adopt splayed Two bors d's oeuveres channel-section steel as lateral stability support carry out wall-attached and be connected and fixed.
