In Figure 19-20, be hingedly connected with closed-loop 354 on the fixed supporting leg 35, attachment device 50 front ends are provided with the open slot 505 that opening makes progress, and closed-loop 354 hangs on the open slot 505, and the blind end of open slot 505 extends down in opposite directions, the double as guide strip.About but closed-loop 354 relative fixed supporting legs 35 are done, the swing on the left and right directions, can overcome the alignment error that attachment device 50 may occur.
In Figure 21, stretch out the front end of building at attachment device 50, vertical welding channel-section steel 101, vertically be welded with shaped steel 103 on the fixed supporting leg 35, its width is less than channel-section steel 101 A/Fs, in its welded top top cover 102 is arranged, top cover 102 extends by under building one side direction along shaped steel, form a slot with shaped steel, width is greater than the channel-section steel web thickness, and its lower end outwards bends, and forms one section gathering sill naturally, top cover 102 is bearing on the channel-section steel 101, and this moment, the whole weight of protective frame unit just was delivered to attachment device 50.In Figure 23, protective frame is in the lifting state.
The preferred connected mode of girt 37 and building 11 can also be the structure shown in Figure 24-25.
In Figure 24, latch 38 injects the hole 381 on the floors 11 and fixes, and hole 381 can set in advance, and also can get out with electric hammer etc.
In Figure 25, latch 38 lower ends are screw thread, are connected and fix with nut 382 in being located at floor.
As can be seen from Figure 26, attachment device 50 is upwards turned up and empty down " bridge " shape profile along making one section on its axis direction especially, adopt such structure, when plane convergence appears in two attachment devices (for example in the building corner), one of them can pass and unlikely interfering from another " bridge " shape profile bottom easily.
From said process as can be seen, the gravity of protective frame unit is that the floor by one deck under newly constructing floor at building bears, because its concrete setting time is longer, intensity higher (being not less than 10Mpa usually) can satisfy requirement of strength fully.And the floor floor face of newly constructing only bears the horizontal shear of transmitting by support body 31 → girt 37 → latch 38 or ground anchor ring 501, and its numerical value is about about 1/3 of protective frame unit gravity, obviously also satisfies requirement of strength.
It can also be seen that from said process, when promoting, under tower crane suspension hook 82 promotes by wire rope 81, the articulating device of protective frame unit is convenient to separate, and after lifting put in place, the operator only need stand in the building, fixed supporting leg is aimed at, transferred the tower crane wire rope and can realize installation in position.Whole process is simple, safety, do not need very high know-how technical ability, the common laborer just can be competent at after by simple training, user-civil engineering unit for protective frame, this task can be given for example punching block work team group of other operation teams and groups fully, the preparatory stage interior (time about 6 hours is arranged usually) of utilizing the flooring concrete pouring to finish before the last floor construction of back finishes.
