Have by way of welding and being hinged, using preceding with reference to drawing dimension of opening and floor absolute altitude, choose each mounting hole on channel-section steel
Point, is assembled with pin.Every time in use, need to only the platform assembled be promoted into relevant position, operating platform with tower crane
The edge of the rectangular shaped rim 1 of upper end abuts concrete shear force wall 14, and the leg 4 of the lower end of operating platform upper end is carried on floor 15
On, vertical channel-section steel naturally downwards, to prevent operating platform lateral sliding, makes operating platform four in the inner side of concrete shear force wall 14
The dependence point up and down that is forced through at angle is reached in operating platform structure, it is ensured that the stability of operating platform.The present invention not only ensures
The stability and security of support platform, also greatly reduces materials'use and labour cost, and construction is flexible, prevents
Shield is simple.
Operating platform of the present invention installs the first mounting hole 5, the 3rd mounting hole 10 and the 4th when adjusting height
Pin at hole 12 is removed, and skewed horizontal load 3 is adjusted to appropriate length, and locks corresponding 3rd mounting hole 10 by pin,

The mounting hole 12 of hole 5 and the 4th.
Operating platform of the present invention pacifies the first mounting hole 5, the second mounting hole the 8, the 4th when adjusting planar dimension
Hole 12 is filled, rectangular shaped rim 1 is adjusted to suitable dimension, and corresponding second mounting hole 8 is locked by pin, by skewed horizontal load 3
Rotated around the pin joint in rectangular shaped rim 1 to proper angle, the corresponding peace of first mounting hole 5 and the 4th is locked by pin
Fill hole 12.
Operating platform of the present invention uses Triangle Principle, to ensure stress support system steadiness.Specifically make
Used time：
1）Landing slab uses 4# side using the thick checkered steel plates 16 of 3mm, length and width 10cm small compared with elevator dimension of opening, four keel
Steel pipe, it is respectively away from steel plate edge 60cm, the welding of well word.At two angles of the side of rectangular shaped rim 1,14# channel-section steel conducts are welded
Vertical supporting 2, is hinged 14# channel-section steels as skewed horizontal load 3, vertical supporting 2 is used with skewed horizontal load 3 in the opposite side of rectangular shaped rim 1
Pin is connected, and specific tie point and length are according to live actual ruling.
2）To ensure that the entirety of the operating platform is consolidated, cross-brace is used as with 14# channel-section steels at the 1/3 of vertical supporting 2
11 are connected with skewed horizontal load 3；Vertical supporting 2 is handled by 5.4m floor heights, selects 5.5m elongated, sets the inner side of concrete shear force wall 14,
Card support effect is played, platform lateral sliding is prevented, while pad is reduced, to reduce the shadow in flat top to welding position
Ring, it is ensured that its stability.
3）To adapt to the service condition of different floor heights, the position in the blunderbuss hole of the ￠ 16mm on 12.6# channel-section steels, blunderbuss hole are calculated
Number is according to the ruling of field layer High variation point.According to different floor heights during practical operation, stretch skewed horizontal load 3, and chooses the blunderbuss of diverse location
Hole（That is the 3rd mounting hole 10）Assembled, blunderbuss hole count is according to the ruling of field layer High variation point.Because of floor height in actual production process
And dimension of opening is indefinite, specific channel-section steel length, punching quantity and punch position need to be appraised and decided again.
4）To adapt to different dimension of opening use requirements, the length of the second channel-section steel 7 is 300mm, and the one of the second channel-section steel 7
End sets multiple spacing 50mm ￠ 10mm blunderbuss hole, and outside socket joint 16A# channel-section steels set multiple as the first channel-section steel 6, and thereon
Spacing 50mm ￠ 10mm blunderbuss hole, blunderbuss hole count is defined according to site dimension change number.During practical operation, according to different dimensions of opening, choosing
Take corresponding blunderbuss hole（That is the second mounting hole 8）After being assembled, onsite application is put into.In actual production process, because size is indefinite, need
Again channel-section steel length, blunderbuss hole number and position are appraised and decided.
To sum up, different floor heights are applicable to by means of the above-mentioned technical proposal of the present invention, various sizes of elevator hoistways,
Its height and planar dimension can be adjusted flexibly as needed, easy to use, it is to avoid routine operation platform is taken repeatedly to be torn open, is applicable chi
Very little single the problem of, remarkable in economical benefits；This operating platform makes simple, flexibility using the processing of the materials such as conventional channel-section steel
By force, the usage amount of the circulation materials such as steel pipe, scaffold board is reduced, it is to avoid operating platform high-altitude in elevator hoistways is taken repeatedly tears open
Situation, reduce potential safety hazard, improve the security of workman's operating environment.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
