The edge of a wing 215 and the second lower part edge of a wing 216, two neighboring first arcuation channel steel 211 is fixed by first end plate 23, first end plate 23
One end of the first arcuation channel steel 211, the upper surface of first end plate 23 and lower end surface difference are fixed to by welding or other means
It fits with the second top edge of a wing of the first arcuation channel steel 211 and the second lower part edge of a wing, the through hole issued in first end plate 23
26, it dismountable mode such as is bolted and connects to form the first circular support 21；First arcuation channel steel 211 and the second arc
Shape channel steel 221 is connected and fixed by the second support combinations connector 27, specifically, by multiple second bolts and with the second bolt
Multiple second nuts (being in the present embodiment, two the second bolts and two the second nuts) connection matched, Duo Ge
The outside of each of two bolts bolt is set with the second steel pipe and forms the second support combinations connector 27, referring specifically to Fig. 8.
In addition, general arcuation girder steel uses 6m size, that is each arc since the stock size length of channel steel is 6m or 12m
Segment length is general≤6m, the weight after combination both meets in-site installation requirement in the allowed band of lifting equipment, is also convenient for spelling
Dress and combination.
In addition, being also provided with U-shaped fastener connecting hole and hole for hoist on the corresponding position of the first support combinations unit 1.Due to
Caisson wall is arcuation, and each first support combinations unit 1 is different from the angle that the corresponding position of caisson wall 8 connects, pre-buried
Size, the shape of the associated components such as part 3 and U-shaped workpiece also can all change, as long as the both ends of the surface shape of the first support combinations unit 1
Match with the inner wall of caisson wall, referring specifically to Fig. 2 and Figure 10.
It is found that the first support combinations unit 1 is directly placed in bearing workpiece 4 from Fig. 9 and Figure 10, it is not necessarily to other fixed structures
Part, supports workpiece 4 and the embedded board of the built-in fitting 3 in caisson wall is fixed；Second support combinations unit 2 by U-shaped fastener 5 with
First support combinations unit 1 is fixedly connected, and this completes the branch of scaffold assembled support platform in single-unit circular ring shape open caisson
The assembling of support frame frame.
It should be noted that the first support combinations unit 1 and the second support combinations unit 2 can be in factory-assembleds, it can also
To assemble at the construction field (site)；Major trough steel and time channel steel are different size, channel steel of different shapes；Preferably, every section second support
Assembled unit 2 is assembled for one group of progress with two, is set aside on the first support combinations unit 1 using hole for hoist lifting, next group
Row splicing again is closed, reduces on-site consolidation workload in this way；Ensure connection reliability；It is above-mentioned to be merely to illustrate, it cannot understand
At limitation of the present invention.In circular open caisson the joint number of scaffold assembled support platform can according to the depth of practical open caisson come
It determines.In addition, the middle section that scaffold assembled support platform surrounds in above-mentioned circular ring shape open caisson can also lay nylon peace
Scaffold assembled support platform forms plane entirety in the whole network, with circular ring shape open caisson, to avoid scaffold is being set up subsequent
And personal height falls in the follow-up works such as shuttering supporting operation, concreting, it is ensured that construction operation safety.
Compared with prior art, scaffold assembled support platform is detachable in more piece circular open caisson of the invention, scene
Assembling is easy, and reduces field operation workload, saves the activity duration, improves working efficiency；Force structure can be recycled repeatedly
It reuses, saves material；Primary structure member edge-on can be placed, and excessive site space is not take up, and live civilized construction conforms to
It asks；Structural system is safe and reliable, guarantees construction safety.In addition, scaffold assembled support platform application in open caisson of the invention
Extensively, upper falsework body, support system and constructing operation force structure and operating platform be can be used as such as.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.
