Description
Technical field
The present invention relates to a kind of installation methods of half-through tubular arch sunpender.
Background technique
When installing sunpender on half-through tubular arch, sunpender one end is anchored on girder steel, and the other end is anchored at arch rib lower chord tube
On the anchor slab of center.
Progress arch rib hanger erection, which mostly uses, under existing technical conditions is first mounted on the upper anchor point of sunpender on arch rib
Anchor head, then the anchorage of sunpender is mounted on girder steel lower anchor end.Such method needs in advance lift sunpender under
Portion penetrates anchor head, and since lower part girder steel does not install the people that can not stand, operating platform is limited, penetrate diameter be 900 large steel pipe it
Between, tensioning platform only has 80cm × 100cm, and personnel's trick is limited, and from length 172cm, the steel sleeve of internal diameter 217mm penetrates outer diameter
The sunpender anchor head of 200mm, required precision is quite high, difficult quite big；Then in steel beam lifting by sunpender lower tine ear and steel
Beam anchor case lifting lug is connect by steel pin pivot pin；The adjustment for carrying out Suo Li is finally enabled according to the lifting that monitoring unit is provided.
Disadvantage of the existing technology:
1, it is small first to install anchor head job platform, construction is limited, and speed of application is slow, and construction safety coefficient is low.
2, the construction period is long, specially takes out the time and carrys out tying up bar, seriously affects the duration.
3, since the housing bore of sunpender only has 217mm, anchor head outer screw diameter is 200mm, and the gap penetrated is small, and outer
Casing has 172cm long, has larger requirement to the straight degree of sunpender, difficulty of construction is big.
Summary of the invention
The present invention provides a kind of installation methods of half-through tubular arch sunpender, and which overcome described in background technology existing
There is the deficiency of technology.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of installation method of half-through tubular arch sunpender, in advance casting anchor sunpender anchorage and girder steel end in the venue
End part anchoring, then allows sunpender to lift together with girder steel, and hoist engine is placed on the girder steel lifted and pulley blocks come
Anchor point on sunpender is pulled to reeve, auxiliary enters hole manually to pull sunpender using traction rope, installs the nut of anchor point on sunpender
It is positioned；Require a progress sunpender in advance to tight according to the linear absolute altitude of girder steel in installation process, it is complete to all hanger erections of full-bridge
At the whole the adjusting of suspender power of rear progress.
Among one embodiment: during the hanger erection, anchor point is equipped with guiding cap, the hoist engine and pulley thereon
Group is by pulling the guiding cap of anchor point installation on sunpender to reeve.
The technical program compared with the background art, it has the following advantages:
1, just the anchorage of sunpender is installed in place before steel girder erection, saves the time, while constructing from high-altitude will
Anchorage penetrates the risk of girder steel anchored end.
2, anchor point on sunpender is connect with the upper anchor head on arch rib again after girder steel is in place, girder steel provides for operating personnel
Job platform, personnel can reach sunpender vertical base and conveniently reeve.
3, it is constructed using hoist engine, speed is accelerated, and mechanization degree is high.
4, guiding cap auxiliary device is installed on sunpender anchor head additional, difficulty of reeving substantially reduces.
5, hanger erection is completed without cable force adjustment, only require to carry out to save to tight in advance according to line style have bad luck it is very heavy
The time and cable force adjustment time on top, greatly accelerate speed of application.
6, hanger erection and the reinforcing of girder steel Bolt carry out simultaneously, and change key job is greatly saved into non-key work
1 month time duration will be expended by reeving in advance；Benefit has been created for enterprise, has won the favorable comment of owner.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the main view of half-through tubular arch described in the present embodiment.
Fig. 2 is the side view of half-through tubular arch described in the present embodiment.
Specific embodiment
Please refer to Fig. 1 and Fig. 2, a kind of installation method of half-through tubular arch sunpender provided by the invention are as follows: on the scene in advance
By the end part anchoring of casting anchor of 10 anchorage of sunpender and 20 end of girder steel in ground, sunpender is then allowed to lift together with girder steel 20,
Hoist engine and pulley blocks are placed on girder steel 20 through having lifted to pull anchor point on sunpender 10 to reeve, and are assisted manually to utilize
Traction rope pulls sunpender 10 and enters hole, and the nut for installing anchor point on sunpender 10 is positioned；It is linear according to girder steel 20 in installation process
Absolute altitude requires only to carry out sunpender in advance to tight, and 10 cable force adjustment of whole sunpenders is carried out after all sunpenders 10 of full-bridge are installed.
The installation method specifically includes process in detail below:
10 anchorage of sunpender end part right angle setting and is anchored with casting anchor for 20 end of girder steel in the venue by crane, is convenient for
Steel pin axis penetrates, and speed is fast, safer.
Hoist engine is placed in bridge floor as power and has set up on girder steel 20, and installing leading block in 20 front end of girder steel in place will
Wirerope is oriented on arch rib, is hung directive wheel in arch rib eminence and is again turned to wirerope from the sunpender outer steel pipe of internal diameter 217mm
It wears, on the guiding cap for hanging over 10 front end of sunpender, and bolt traction rope assists on sunpender 10.Wherein, leading block and guiding
Wheel constitutes pulley blocks.
Hoist engine to be opened to withdraw wirerope, sunpender 10 is just pulled up, until when outer steel pipe mouth (hole) front end, manually
Dilatory traction rope is adjusted, and since guiding cap is circle, no corner angle can facilitate into outer steel pipe (in hole).
Sunpender 10 was slowly drawn into outer steel pipe, it is interchangeable to be drawn with motor-driven chain hoist, and with 10 top of upper hanger
Screw thread, the nut for installing anchor point on sunpender 10 are positioned.
According to the absolute altitude and camber requirement for having set up beam-ends, screw thread position to be reached is determined, carry out in advance to tight.
Suo Li, which is carried out, after full-bridge closure concentrates adjustment.
Traditional hanger erection mode has been overturned in the installation of sunpender of the present invention, is substantially increased the efficiency of hanger erection, is subtracted
Lack security risk when installing, reduce installation cost, significant effect.
The above is only the preferred embodiment of the present invention, the range implemented of the present invention that therefore, it cannot be limited according to, i.e., according to
Equivalent changes and modifications made by the invention patent range and description, should still be within the scope of the present invention.
