The scaffold is built in bulk, after the horizontal truss at the bottom is assembled in a ground modularization mode, the horizontal truss is hoisted to the installation position in a slicing mode and fixed, and then the fastener type steel pipe scaffold is built layer by layer according to the construction progress.

And 3, fixing the wall attaching support with the outer wall of the building, clamping the top support of the wall attaching device with the stop lever of the main frame, connecting the clamping plate assembly with the vertical steel pipe, fixedly connecting the clamping plate assembly with the wall attaching support, and pressing the stop lever above the clamping plate assembly on the vertical steel pipe at the top of the clamping plate assembly.

Specifically, every machine position installs a plurality of wall devices that attach from bottom to top, it attaches the wall support to begin the installation from the upper strata on standard layer, wear the wall bolt and penetrate in the bolt hole of reserving on the building, will attach wall support and wall body fixed connection, cardboard subassembly and vertical steel pipe encircle and are connected, the cardboard subassembly passes through the bolt and attaches the wall support fixed, rotatory shore makes brace support groove 621 and pin joint, and make support groove and pin top tight through adjusting screw, accomplish to attach being connected of wall device and mounted frame, install according to the construction progress and attach the wall support one by one, a floor height is constructed in every time, after waiting to change over to the upper strata, on current scaffold layer on the overlap joint next step scaffold layer, repeat this process until accomplishing the buildding as the scaffold.

Step 4, installing a conversion layer on the top of the scaffold, building a second bottom horizontal truss 4 on the top of the conversion layer, and repeating the step 2 and the step 3 until a second attached suspension frame is built;

for example, the conversion layer is the conversion frame, a plurality of switching frames are installed at the top interval of scaffold, the switching frame passes through the cross fastener and is connected with the scaffold, adopt 4 lifting ropes to be in the four corners of the bottom horizontal truss of well assembling and ensure balance, two people both sides hold the bottom horizontal truss steadily to lift by crane, two people both sides hold the second bottom horizontal truss steadily to fall on the conversion frame during the unhooking, adopt the cross fastener to connect second bottom horizontal truss and conversion frame, realize the connection of two mounted frames fast.

Step 5, dismantling the conversion layer of the first attached suspension bracket, disconnecting the first attached suspension bracket from the second attached suspension bracket, and using the construction part of the first attached suspension bracket for constructing a third attached suspension bracket;

the method for detaching the attached suspension bracket comprises the following specific steps:

the split unit is defined to the mounted frame according to the position of the lower main frame, a lower main frame or two lower main frames are used as a whole split unit, the whole mounted frame is made to form a plurality of split single sheets, the connection between the units is disconnected, the top support and the vertical steel pipe of the wall attaching device of the dismounting unit are separated, the clamping plate assembly is dismounted, then the scaffold is scattered and dismounted from top to bottom, after the bottom horizontal truss is dismounted, the formed accessories are dismounted and used for the third wall attaching mounted frame to be built.

According to the invention, in the construction process of the suspension frame, the bottom horizontal truss is firstly constructed by the upright rods and the lower main frame, then the scaffolds are constructed layer by layer on the bottom horizontal truss according to the construction progress, the vertical steel pipes of the scaffolds are butted with the bottom horizontal truss through the butt joint fasteners, the construction efficiency of the suspension frame can be improved, each machine position of the whole attached suspension frame is connected with a building by adopting a plurality of wall attaching devices, compared with the traditional suspension frame and the existing novel suspension frame, a fixing mode of hundreds of cantilever steel beams is adopted, the construction time is saved, a rotary layer is arranged at the top of the scaffold and is used for connecting the next suspension frame, the quick connection of the upper and lower suspension frames is realized, and the construction efficiency of the suspension frame of the whole building is improved.

Compared with the traditional dismantling process that the U-shaped embedded parts need to be cut and workers pull out each cantilever steel beam one by one to lift away when the cantilever brackets are in the air, the method only needs to dismantle the switching layer, and then the constructors can finish dismantling the wall attaching device by standing on the construction layer, so that the whole suspension bracket can be dismantled in units, and the efficiency and the safety of dismantling the suspension bracket are improved.

Compared with the dismantling process of a flower basket cantilever frame, the dismantling process of the suspension frame has the advantages that the overhanging steel beams of the novel cantilever frame adopt the wall attaching type structure, when the suspension frame is dismantled at high altitude, constructors need to stretch out bodies of the novel suspension frame outdoors, operation risks are increased, the suspension frame constructors can achieve dismantling of the wall attaching devices by standing on a construction layer, safety of the constructors is improved, the number of the wall attaching devices is far smaller than that of the overhanging steel beams, and dismantling speed is greatly improved.

The above contents are only for illustrating the technical idea of the present invention, and the protection scope of the present invention should not be limited thereby, and any modification made on the basis of the technical idea proposed by the present invention falls within the protection scope of the claims of the present invention.
