Owing to the hanging structure adopted by the utility model, the scaffold can be conveniently and quickly mounted and dismounted, and occpies little time of steels and cranes, so that the construction cost is greatly reduced. The utility model is used for structural construction as well as decorative construction. The utility model has low requirements for procedure and construction progress and is difficult to result in holding up the work.

Description

Hanging lift scaffold

The utility model relates to the scaffold that is mainly supported by the house.

Scaffold is a requisite facility in the building operations.In traditional scaffold, have to take steel material very big, work efficiency is low, wind carries greatly, the high-altitude dismantling operation is dangerous, as the overall height scaffold; The construction precision that has requires height, has deviation then to influence safety and progress slightly, the dismounting trouble, and equipment investment is big, and the easy unstability of slide bar is as various hoisting scaffold; The scene mounting or dismounting workload that also has is bigger, and as spigot Frame and Suspension Frame, the frame of encorbelmenting, and it is long to take the crane time, all after the fixation, can take off the crane hook, or the like.

The purpose of this utility model provide a kind of simple in structure, mounting or dismounting are convenient rapidly, it is few to take steel and crane time, the suspended scaffold that cost is low.

The technical solution of the utility model is: a plurality of crab claws are housed at the middle part of common out-mould scaffold framework hang, pressure bearing system is equipped with in the bottom.

During use, crab claw is hung tag on the window wall, pressure bearing system then is supported on the window wall of low one deck.The constructor can go up one deck with scaffold by crane or cucurbit after this floor construction finishes, continue construction.

Describe structure of the present utility model and using method in detail below in conjunction with embodiment of the present utility model.

Fig. 3, crab claw is hung the part schematic diagram,

Fig. 4, the sufficient fixedly schematic diagram of card in the pressure-bearing boots are adjustable,

Fig. 5, inside and outside strut and pressure-bearing boots connection diagram,

Fig. 6, the lifting schematic diagram,

As shown in Figure 1, the out-mould scaffold framework is made of general part, comprises outer vertical rod 7, interior vertical rod 8, bridging 9, interior row's brace 10, the support 12 that prevents unstability outside the plane, hyphen bar 13, security guardrail 14, long transverse lever 15, safety screen 16, scaffold floor 17.Outside framework, also be surrounded by safety net 11.Whole construction out-mould scaffold frame size size can be decided according to concrete condition.The middle part of vertical rod is hinged with a plurality of crab claws extensions 2 in the out-mould scaffold framework, crab claw is hung 2 and is stuck on the window wall of the floor 5 of constructing, and pressure bearing system 1 is arranged at the bottom of out-mould scaffold framework.

Shown in Fig. 2,4,5, pressure bearing system 1 comprises pressure-bearing boots 1,1, adjustable interior card foot 1,2, wild card foot 1,4, internal overarm support 1,6, outer strut 1,7, internal overarm support block 1,5, outer strut block 1,14.All have through hole 1,12 on pressure-bearing boots 1,1 and the adjustable interior card foot 1,2, with wing nut 1,9, screw rod 1,13 and pad 1,11 can be fixed on the appropriate location with blocking foot 1,2 in adjustable, and the pressure-bearing boots are stuck on the window wall securely.Internal overarm support 1,6 and outer strut 1,7 all are the X shape to be installed, and an end is fixed on the framework of constructing, the other end support respectively internal overarm support stop block 1,5 and outside on the strut stop block 1,14.

The also hinged fenestrate wall strengthening support 1,3 in lower end of card foot 1,2 in adjustable.For firm outer strut 1,7, the firm bar 1,8 of outer support is housed on strut 1,7 crosspoints outside, the other end of this bar is fixed on the out-mould scaffold framework.Have link 1,15 to be connected with steel chain 1,16 between internal overarm support 1,6 and internal overarm support block, when making whole scaffold lifting, two parts can not break away from.

Another pith is that crab claw is hung part in the utility model, as shown in Figure 3.Crab claw hangs 2 by other bar 2,1 card of bolt on the wall.For the purpose of firm, the other bar 3 of available horizontal stroke, perpendicular other bar 18 and interim drag-line 4 are further fixing.Horizontal other bar 3 is inserted in crab claw and hangs in 2, and interpolation is erected other bar 18, and perpendicular other bar 18 upper ends are strained and fixed in interior vertical rod 8 with interim drag-line 4, prevent the horizontal unstability of out-mould scaffold framework upper.

Can use crane lifting during use.As shown in Figure 6, be after the first floor construction finishes, in the time of carrying out the upper strata construction, the installation process schematic diagram of hanging Lifting scaffold.Earlier with card foot 1 in adjustable in the pressure bearing system, 2, crab claw is hung the other bar 2 of bolt on 2,1 and interim drag-line 4 etc. unclamp, crane is upwards sling one section with hanging Lifting scaffold, make pressure bearing system 1, crab claw is hung 2 and is broken away from wall, crane outwards shifts out hanging Lifting scaffold then, be moved upward to upper floor again, then move inward, make pressure bearing system 1 and crab claw hang 2 be in wall directly over, crane puts down hanging Lifting scaffold then, pressure bearing system 1 and crab claw are hung 2 and are promptly blocked on the wall, with card foot 1 in adjustable, 2 and the other bar 2 of bolt, 1 tightens, and this moment, crane can be removed, further again fixed casement window wall strengthening support 1,3, horizontal other bar 3, perpendicular other bar 18, interim drag-line 4, the constructor can construct on scaffold floor 17.

The utility model has been removed pre-embedded bolt to the demanding trouble of construction precision, thereby mounting or dismounting are convenient, rapid.In whole building work progress from bottom to up, this hanging Lifting scaffold progressively promotes, reuse, and of the present utility model simple in structure, but the accessory tool has greatly reduced rolled steel dosage, and operating expenses descends greatly; In installation process, it is few to take the crane time.The utility model not only can be used for structure construction, also can be advantageously used in decoration construction.During construction, a plurality of hanging Lifting scaffolds can be arranged in a row with lap bars and unify, also lifting separately easily, less demanding to operation, construction speed, be difficult for causing the work holdup.Jacking equipment can be used crane, also available cucurbit, or both are used alternatingly.In addition, because the utility model height is certain,, make construction be subjected to weather effect less so can adopt safeguard procedures easily.
