for example, the conversion layer is the conversion frame, a plurality of switching frames are installed at the top interval of scaffold frame, the switching frame is connected with the scaffold frame through the cross fastener, adopt 4 lifting ropes to tie in the four corners of the horizontal truss of bottom that the equipment is good and ensure balance, two people hold up the steady lifting by crane of bottom horizontal truss on both sides when lifting by crane, two people hold up the horizontal truss of second bottom and steadily fall on the switching frame on both sides when falling the hook, adopt the cross fastener to connect horizontal truss of second bottom and conversion frame, realize the connection of two mounted frames fast.

Step 5, removing the conversion layer of the first attached hanging frame, disconnecting the first attached hanging frame and the second attached hanging frame, and using the constructional element of the first attached hanging frame for constructing a third attached hanging frame;

the method for detaching the attached hanging frame comprises the following steps:

dividing the hanging frame into split units according to the positions of the lower main frames, forming a plurality of split single sheets according to one lower main frame or two lower main frames, disconnecting the units, separating the top support of the wall attaching device of the dismantling unit from the vertical steel pipes, dismantling the clamping plate assembly, then carrying out scattered dismantling on the scaffold from top to bottom, and after the bottom horizontal truss is dismantled in a split manner, using the dismantled fittings for constructing a third wall attaching hanging frame.

And 6, repeating the step 4 and the step 5 until the construction of the attaching suspension frame of the whole building engineering is completed.

In the construction process of the suspension frame provided by the utility model, the vertical rods and the lower section main frame are firstly adopted to construct the bottom horizontal truss, then the scaffold is constructed layer by layer on the bottom horizontal truss according to the construction progress, the vertical steel pipes of the scaffold are in butt joint 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 attachment suspension frame is connected with a building through a multi-channel wall attaching device, compared with the traditional suspension frame and the existing novel suspension frame, the construction time is saved by adopting a fixing mode of hundreds of suspension steel beams, the rotation layer is arranged at the top of the scaffold and used for connecting the next suspension frame, the quick connection of the upper suspension frame and the lower suspension frame is realized, and the construction efficiency of the suspension frame of the whole building is improved.

Compared with the traditional suspension frame which needs to cut the U-shaped embedded part, and then workers face to empty to withdraw and hang each suspension type steel beam one by one in the dismantling process of the suspension frame, the method only needs to dismantle the transfer layer, and then constructors stand on the construction layer to complete the dismantling of the wall attaching device, so that the whole suspension frame unit can be dismantled, and the efficiency and safety of dismantling the suspension frame are improved.

In the dismantling process of the hanging frame, compared with the dismantling process of the basket hanging frame, the hanging type steel beam of the novel hanging frame adopts the wall attaching structure, when the hanging frame is dismantled at high altitude, a constructor needs to extend the body outdoors, so that the operation risk is increased.

The above is only for illustrating the technical idea of the present utility model, and the protection scope of the present utility model is not limited by this, and any modification made on the basis of the technical scheme according to the technical idea of the present utility model falls within the protection scope of the claims of the present utility model.
