Specific embodiment
The utility model is further illustrated with case study on implementation below in conjunction with the accompanying drawings：
Explained in detail referring to Fig. 1-7 case study on implementation：A kind of absolute altitudes such as large span spatial structure high position band post Sliding Structures, including support
The intercolumniation beam 2 that steel column 1 is vertically fixedly connected with brace steel post 1, is equipped with sliding rail 3 on intercolumniation beam 2, sliding on sliding rail 3
It is dynamic to be provided with by sliding steel column 4, be fixedly installed piston shoes 9 by the both sides of sliding steel column 4, the piston shoes 9 of side be slideably positioned in
Hydraulic top thruster 10 on sliding rail 3 is connected.
Adjacent described being horizontally disposed between sliding steel column 4 has inter-tie 8 and intersecting to be provided with intersection tie-rod 7,
Inter-tie 8 and intersection tie-rod 7 are located at by the same tie point on the post outer peripheral face of sliding steel 4；The wherein lower edge of inter-tie 8 and institute
Piston shoes 9 are stated to be connected.
Described that sliding steel column 4 and the junction of sliding rail 3 were provided with rail hole 6, this crosses rail hole 6 with the sliding
Track 3 is matched；The brace steel post 1 and be provided between sliding steel column 4 expansion shrouding 11.
A kind of absolute altitudes such as large span spatial structure high position band post gliding method, comprises the following steps：（1）It is determined that sliding work
, be divided into steel column by sliding steel column 4 and brace steel post 1 as boundary with sliding working face by face；
（2）Rail hole 6 is crossed in factory's cutting completion, piston shoes 9 and by sliding steel column 4 in factory by the bottom of sliding steel column 4
Spelling is completed, and is together delivered to scene；
（3）After brace steel post 1, intercolumniation beam 2 and sliding rail 3 are installed in place, first sliding is carried out in slipping and assembling area
The high-altitude spelling of unit, comprising by sliding steel column 4 and piston shoes 9, inter-tie 8, intersect tie-rod 7, roof structure 5 and hydraulic pressure and climb
Row device；After the completion of assembly, a step pitch is slid forward；
（4）Continuation carry out second high-altitude spelling of sliding element in build-up area, and carried out with a upper sliding element it is right
Connect, after the completion of assembly, a step pitch is slid forward；

It is fixed, hole upside and the left and right sides with a distance from sliding rail all should >=10mm, it is ensured that sliding rail can be passed through and slid
Steel column；By opening up rail hole, made by the lateral Displacement that sliding steel column plays roof system span direction during sliding construction
With raising construction safety performance.
The piston shoes 9 are arranged at the every both sides by sliding steel column 4, and bottom is fallen within sliding rail 7, piston shoes bottom mark
Height crosses the upside of rail hole 6 about 10mm~15mm in steel column, makes to be slid steel column and is come to nothing with sliding rail, prevents sliding construction mistake
Damage is produced to structure in journey.
The hydraulic pressure creep machine 6 is connected with piston shoes 9 by pushing tow otic placode, is the dynamical system during whole sliding construction
System, uses with the coordinative composition of equipments such as hydraulic power system, computer control system, displacement transducer and pressure sensor.Hydraulic pressure
Crawl device is manipulated using computer system completely in the propulsive force and fltting speed of slipping, by wedge type fixture block it is unidirectional from
Lock function, auto lock sliding rail is creeped using middle hydraulic jack driving structure, is constructed by sensor real-time monitoring
Dynamic.
The expansion shrouding 11 is arranged at the top of brace steel post 1, shrouding radius=steel column radius+1.5t（T is thick shrouding
Degree）, for adjusting after the completion of sliding construction by sliding steel column（4）With the horizontal departure between brace steel post 1.
Rail hole 6 and piston shoes 9 are crossed by steel column, make by slide between steel column 4 and brace steel post 1 reserve butt seam≤
15mm, is directly docked after in place by sliding steel column sliding construction with bottom brace steel post, finally cuts off piston shoes and sliding rail
Road, benefit filled tile at rail hole, in solving traditional sliding construction technique, need to mend behind structure sliding position fill after fill section or
Need the technical barrier of high-altitude dropping place.
Specific implementation of the present utility model is described above.All institutes within spirit of the present utility model and principle
