After above operation completes, then the otic placode 13 for carrying out the making of on-the-spot welding specialized factory.Level weld seam requirement is put down during welding
Cunning is full, must not there is the weld defects such as stomata slag inclusion, and quality must be guaranteed.
7. tower crane attachment frame is installed
Each of frame will be adhered to and acts the setting height(from bottom) for being raised to attachment frame respectively, same absolute altitude is located at attachment point needed for tower body,
With 8# iron wire fixations, first will entirely adhere to frame leveling, then each attachment ring beam frame is connected fastening with tower body.
8. tower crane is installed brace bar attached
After brace bar attached b is adjusted into installation site with tower crane, after be firmly linked with for safety belt by operating personnel, with the bottle gouard moved by hands of 2t
Brace bar attached b is lived near attachment frame layback, the bearing pin near wall side is first installed.4 strut b of attachment are installed successively
Near the bearing pin of wall side.
Sling section standard knot a to jacking when trim position.Whether tower crane perpendicularity is observed from both direction by theodolite
Meet and require, no more than 2/1000, attachment frame above tower body perpendicularity is no more than 4/ for the following tower body perpendicularity of attachment frame
1000.Attachment frame side bearing pin is installed, when perpendicularity is unsatisfactory for requiring, dolly is slow by when perpendicularity meets requirements above
Movement makes attachment pull bar be in unstressed condition, while rotating tower crane, the bearing pin of attachment frame side is installed after perpendicularity is mixed up.
After tower crane perpendicularity reaches requirement, the bearing pin of attachment frame side is installed.4 strut b attachment frames one of attachment are installed successively
The bearing pin of side.
9. tower crane jacking
Hydraulic work system is had to check for before jacking whether normal.One section standard knot is hung into climbing support and introduces platform.Will
Loading trolley reaches jacking balance position.Using trainstop, do not allow tower crane to turn round, unload tower body top and connect with undersetting
8 bearing pins for connecing.Hydraulic system is started, is made to climb pawl and is rested on the marking time of closest tower body, then operate hydraulic system to cover
Frame is slightly risen, and checks whether the drive disk assemblies such as jacking hanging plate, climbing support have abnormal sound, deformation, after confirming normally, continue jacking.
(note：It is provided with special messenger station is marked time in groove and inserted, extracts safety pin whether lower platform observation raising plate hangs over) push up to about
More than 1/3 standard knot height and make on climbing support changing step push rod be located at mark time top when, oil cylinder is packed up, change top of marking time
Rise.Being repeated twice rear tower body top should have one space of standard knot of loading.The standard knot introduced on platform is being caused into tower body just
Top, aligns undersetting and is connected bearing pin with standard knot, plugs interim bearing pin, releases and introduces dolly, the new standard knot introduced of alignment
With company's bearing pin of side standard knot, bearing pin is inserted.It is above a lifting guide support adding process, continuous supernumerary segment completes jacking operation.
Above operation must carry out strict quality control, specially：
All levels of management personnel is organized before going into operation, drawing is conscientiously familiar with, organization unit's engineering construction organization design and special project are applied
Work scheme, specifies qualifying point and quality requirement.With reference to construction drawing and technical specification, the work of confiding a technological secret before construction is carried out
Make, all personnel for participating in construction is grasped respective working procedure and main points of operation, construction reference, method and quality will
Ask.
Strict implement national regulation, standard and construction technology in construction, strict technical training warp is carried out to special work post
On duty can be operated after passing the examination.
High-strength bolt on attachment frame must be tightened, and the internal overarm support of adjacent two standards internode must be installed, and every tower crane is matched somebody with somebody
A set of internal overarm support is put, internal overarm support is arranged on one attachment device topmost.
Tower crane attachment must measure perpendicularity before installing, and to the undesirable tower crane of perpendicularity, can be installed after rectification
Brace bar attached b.
All attachment pull bars forbid directly welding using being hinged.
Forbid superelevation, attachment above cantilever height is no more than the requirement that specification and scheme specify.
Wall ear mount is bilayer MC120B：Two panels ear mount spacing is controlled in 50mm or so, bearing pin length (A30 × 70mm),
If spacing is excessive, the bearing pin of standard configuration is not enough used, and spacing is too small, can cause pull bar installation difficulty.
The a diameter of 30mm of wall ear mount pin-and-hole, without increasing, it is ensured that Anchored Bar and ear mount pin joint, pin-and-hole crosses conference causes tower
Body is rocked seriously, and the angle of inclination of brace bar attached b is no more than 10 °.
Attachment plane, facade are please performed in strict accordance with this method, and attachment horizontal layout does not allow arbitrarily change.Attachment facade
Arrangement allows to move up and down 1 section standard knot.
Before coming into operation, it is necessary to by checking and accepting, acceptance(check) rear can be used.After examination is come into operation, anyone must not
Tear down and reconstruct without authorization.
