It is placed between I-steel and another secondary beam, makes the overall stepped operating platform of presentation.
Preferably, safety net is laid in sliding support frame bottom.
The utility model in terms of existing technologies, has the advantages that：
1st, permanent protective property
It is basically identical with reticulated shell shape at the top of support frame, in top secondary beam putting up platform operating platform, in support frame lower berth
If safety net, operative employee is played a protective role.
2nd, flexibility is good
Dragging track is laid under support frame, can be moved with reticulated shell installation site.
3rd, large-span arch construction speed is accelerated.
Support frame only needs to set up once, and support frame can move with reticulated shell installation progress, it is possible to reduce remaining support frame
Time and expense are set up, improves the integral construction speed of reticulated shell.
4th, installation accuracy is high.
Before single span reticulated shell is not closed up, the deflection deformation of reticulated shell can be caused by installing remaining reticulated shell, so as to influence remaining reticulated shell
The installation accuracy of rod member, overall deflection deformation can effectively be controlled by being constructed on the support frame, be reduced caused by construction loads
Construction error.

Embodiment
The utility model is further elaborated and illustrated with reference to the accompanying drawings and detailed description.In the utility model
The technical characteristic of each embodiment can carry out respective combination on the premise of not colliding with each other.
As shown in figure 1, a kind of mesh shell slippage support frame, including top platform 1, jack truss 2, pylon post 3, sleeper 4, sliding
Track 5, pulley 6, limiter 7, reticulated shell 8.4 pylon posts are provided with sliding support frame, as vertical load-carrying construction.Pylon post 3
Middle part is welded with 3 primary and secondary truss as shown in Figure 2, and each primary and secondary truss is made up of main couple and jack truss 2.The present embodiment
In, as shown in figure 4, welding 3 primary and secondary truss on pylon post 3 altogether, pylon post 3 forms Framework System with primary and secondary truss, most
Bottom primary and secondary truss is not more than 600mm away from pylon column bottom, to keep stability.Wherein, the primary and secondary truss of the top is as net
The top platform 1 of shell construction operation, its main couple 101 and jack truss 2 are arranged at the top of 4 pylon posts.And the primary and secondary truss
In, the trend of main couple 101 moves towards basically identical with reticulated shell to be installed, makes the shape of top platform 1 and reticulated shell to be installed also base
This is consistent, is close to below reticulated shell in order to construct.For the ease of erection construction platform, as shown in figure 3, two top main couples
Also it is attached between 101 by some secondary beams 102, secondary beam 102 uses hot rolled H-shaped HN250X125, is welded in top two
Between main couple.The welding H-bar on the secondary beam 102 of top platform 1 continues, steel bridging piece is then horizontally disposed with, is positioned over I-shaped
Between steel and another secondary beam, make the overall stepped operating platform of presentation.
As it can be seen in figures 5 and 6, the bottom of pylon post 3 is provided with the slide device for being used for driving upper frame system to move, sliding dress
Put including pulley 6 and the sliding rail 5 supporting with pulley 6, bearing of trend is the design glide direction of sliding support frame.Set
The place of sliding rail must be smooth, and dragging track laying work area must be tamped, and foundation bearing capacity, which reaches design requirement, to be entered
Row laying track；One section of 500mmx1500mm sleeper 4 is arranged every 1.5m under sliding rail 5.This support frame need to lay two
Bar sliding rail 5, for every track using channel-section steel as guide rail, channel-section steel laying needs straight, channel-section steel bottom and the panelling of sleeper 4.This implementation
In example, the row's column bottom of centre two of bottom column trestle 3 sets pulley 6, and the row's column bottom of outside two sets fixed support 7, fixed branch
Frame can be used as limiter temporarily,, can be with order to prevent whole support frame from continuing to slide when pulley 6 slides into target location
It is fixed using fixed support 7 with ground, keeps stability.
In addition, in order to strengthen the stability of whole support frame, pylon post 3, main couple 101 and jack truss 2 can be used
Diagonal web member 202 carries out reinforcement of weld.Pylon vertical rod, primary and secondary chord member of truss 201 and diagonal web member 202 use pipe.Sliding branch
Safety net is laid in support bottom, to ensure the safety of construction worker.
This engineering method is applied to Large-span Reticulated Shell Construction, and the specific scope of application is as follows：
1st, structure type is large-span arch construction, and reticulated shell peak is highly no more than 40m.
2nd, dragging track basis must be solid close or poured with strip footing.
Embodiment described above is a kind of preferable scheme of the present utility model, so itself and be not used to limit this practicality
It is new.Those of ordinary skill about technical field, can be with the case where not departing from spirit and scope of the present utility model
Make a variety of changes and modification.Therefore the technical scheme that all modes for taking equivalent substitution or equivalent transformation are obtained, all falls within
In the scope of protection of the utility model.
