Below in conjunction with drawings and Examples the utility model is further described.

As depicted in figs. 1 and 2, in the present embodiment, the support body 1 of scaffold is double, it highly is four and half building building height, efflux on the leger 11 and connect truss 2 by fastener 12, truss 2 is connected with wall-attaching equipment 3 by bearing pin 4, wall-attaching equipment 3 has two, the wall-attaching equipment 3 that wherein is positioned at higher floor is provided with adjustable drawbar 5, adjustable drawbar 5 two ends are passed through bearing pin/bolted splice respectively on truss 2 and wall-attaching equipment 3, adjustable drawbar 5 comprises support 53, have externally threaded adjusting rod 51 and adjusting rod 55, be welded with nut 52 and nut 54 on the support 53, it is identical that wherein adjusting rod 51 and nut 52, adjusting rod 55 and nut 54 are formed pitch respectively, the screw pair that rotation direction is opposite.Swinging mounting 53 just can be realized the length adjustment to adjustable drawbar 5, is positioned at that up and down the wall-attaching equipment 3 of floor all can be stressed thereby make.The building side bar on or shear wall be provided with draw ring 6, its optimum method is: before fluid concrete, with nuzzle steel mesh reinforcement in side bar or the shear wall of opening one end of ring, slot on the exterior sheathing of side bar or shear wall, blind end is stretched out, and extension elongation is about 50mm.Wall-attaching equipment 3 front ends are provided with alignment pin 31, and alignment pin 31 injects in the closed-loop of draw ring 6, and the beam supporting of wall-attaching equipment 3 forms being articulated and connected of wall-attaching equipment 3 and draw ring 6 on draw ring 6.Like this, bear the gravity and the working load of support body 1, give building 7 with whole Load Transfer by draw ring 5 by two-layer wall-attaching equipment 3 up and down.A draw ring 6 should be able to bear whole working load, and the diameter of draw ring is not less than 16mm usually.

Draw ring can also be Fig. 3 and another kind of form shown in Figure 4: nut 61 is embedded in the concrete of building 7, bolt 62 passes the connecting hole on the junction plate 64, be connected with nut 61, thereby junction plate 64 is fixed on the building 7, be welded with a closed-loop 63 on the junction plate.Can function as described above equally.But obviously operation does not have said method simple.

When scaffold promotes, connect truss 6 tops with wire rope one end, the other end connects the tower crane suspension hook, starts tower crane, and support body is up carried, and the alignment pin 31 on the wall-attaching equipment 3 is deviate from draw ring 6 automatically.After promoting one deck, the alignment pin 31 on two wall-attaching equipment 3 is aimed at draw ring 6 on the respective storey respectively, decline tower crane suspension hook injects in the draw rings 6 alignment pin 31, and the beam supporting of wall-attaching equipment 3 is on draw ring 6.Tighten up adjustable drawbar 5, make it stressed.Continue decline tower crane suspension hook, loosen fully, take off wire rope, promptly finished the lifting of a scaffold unit until wire rope.Along one week of building outline, arrange a plurality of such scaffold units, the gap is 300mm to about the 400mm between the adjacent cells, adopting close order safety net to seal covers, be connected with the vertical rod of adjacent scaffold unit respectively with several groups of (being generally five to six groups) steel pipes 8, fasteners 9 in addition, as shown in Figure 5, so that form an integral body, increase its integral rigidity around the scaffold unit of building one circle.These several groups of steel pipes 8 are removed before support body promotes, and promote the back that puts in place and recover.Be easy disassembly, steel pipe 8 at least one ends between the best described scaffold unit adopt a rotary buckle to be connected with vertical rod, like this, after removing being connected of steel pipe and other end fastener, rotary buckle one end still is connected with steel pipe, rotates about 90 degree around the active pin shaft of rotary buckle, forwards vertical direction to by horizontal direction, steel pipe 8 still is retained on the scaffold upright rod, makes things convenient for scaffold to promote and put in place back the connection.

In the building main body construction stage, the utility model is the same with protective frame, the every rising one deck of building body, with tower crane scaffold is risen to a last floor and fix, only need just can finish in 4-6 minute the lifting of a unit, it is simple to operate, envelope is covered tight, can well finish the task in main body construction stage, because support body changes double into, its rigidity has obtained enhancing, and in use support body is not easy distortion.

After finishing, the building main body construction stage enters into decoration of exterior wall construction stage sessions, four floor decoration of exterior wall operations when the scaffold place of having constructed, mention scaffold with tower crane this moment, it is fixing behind two floors once to descend, civil engineering workman on the scaffold on two floors the place at draw ring place carry out decoration of exterior wall and repair, because area is little, only about 0.005m ²Therefore will soon finish (usually not can above 20 minutes), scaffold can be moved again two floors and fixing after finishing downwards. 6-8 people just can move 4 floor down to the scaffold in a building in such one day, relative attached lift scaffold, the labour cost that its operation is spent only is about 1/4, running to bit time only is 1/2 effect, and its efficient has obviously improved greatly, and the use cost of scaffold also greatly reduces.

Because the fixed point of above-mentioned scaffold is positioned at the support body middle part, its eccentric moment is little, and two floors and building do not need tie point on top, therefore, coating application technology also can utilize this scaffold to finish, and the coating of such two floors once survives, and its quality is reliably guaranteed.Its underpart two floors do not form hole again because the draw ring area occupied is little on building, therefore mend behind the swabbing and can not form aberration on every side at this place, and quality also can effectively be guaranteed.Therefore, this scaffold not only can be used to carry out the face brick construction technology, also can carry out coating application technology.Compare protection rack special for building main body construction, under the situation that increases a little use cost (accounting for 1/4), its function is expanded, and range of application also increases greatly, total cost is compared the attached lift scaffold that possesses identical function and is only accounted for about 1/3, greatly reduces cost.

Steel pipe and the fastener of more than setting up the scaffold support body can be that the external diameter of using always is steel pipe and the common fastener of 48mm, wall thickness 3.5mm, and also can adopt external diameter is steel pipe (external diameter 36mm is for more preferably selecting) and the supporting with it fastener of 32-40mm, wall thickness 3.0mm.If adopt the latter, under the prerequisite of the intensity that has guaranteed support body, rigidity and stability, the weight of steel pipe and fastener is compared with the former and has been saved about 30%, greatly reduces the unit area steel quantity consumption of scaffold, and its economic benefit and social benefit are all very remarkable.
