Description

Universal lifting scaffold

The utility model relates to the suspended scaffold by the house supporting that the building operations personnel use, and specifically is meant a kind of omnipotent raise scaffold many, highrise building that is used for.

For a long time, traditional external scaffolding of using in many, the high-building construction, as fastener steel tube frame, hanger-hanging basket system etc., all exist problems such as the material consumption amount is big, fund input is many, holding time is long, degree of safety difference to some extent, make the outrigger engineering become headachy one difficulty in many, the high-building construction.Several raise scaffolds that are attached in the building structure successively occurred in China in recent years, they have overcome the above-mentioned shortcoming of traditional scaffold preferably, but also exist some problem and shortage.Such as integral hoisting scaffold wherein, attached wall self Liftable type scaffold and unsettled attached wall rail mounted scaffold, the scope of their utilizations all is confined to the construction of single highrise building shear wall structure, and accounts for other very big structure division of ratio in the building, still can't use.And for example recent attached plate, the attaching beam formula lifting false work that occurs, though can solve the construction of beam, plated construction, but these shelfs are when satisfying corresponding construction, also must satisfy the requirement of corresponding floor height, that is to say, when building structure difference or floor height change greatly, all also need shelf is designed again and processes, its recycling chance is few, and standard and versatility are poor, and this is very uneconomical economically.

The purpose of this utility model is to overcome the shortcoming that above-mentioned raise scaffold exists, and a kind of extremely strong many, omnipotent raise scaffold of highrise building that forms approved product of versatility that adapts to different building structure and different layers high request is provided.

Solution of the present utility model, at first still, as the method for setting up common steel tube fastener scaffold, set up by what standard scaffold tubes and fastener etc. were formed and be divided into some groups scaffold around building one week but by certain length, the feature part of omnipotent raise scaffold is to have and the steel tube fastener scaffold can be hung the general part that is fixed on the building structure facade; Have the guide rail that play the guiding role when being used for the shelf lifting and contact with guide rail but the sliding part that only can slide up and down along guide rail, its middle guide has the structure that can temporarily be connected with general part, and sliding part also has the structure that can temporarily be connected with the steel tube fastener scaffold.

The utility model with said structure is when concrete the use, should will hang respectively on the facade of building around the some groups of steel tube fastener scaffolds in one week of building external by general part earlier, its specifically the method for hanging be, formerly on construction every layer of structure of one to two layer well, along vertical vertical alignment alternating floor building distance, along continuous straight runs is reserved horizontal through hole every certain distance, bolt and nut component by general part, general part is fixed in the building structure, vertical rod and general part in the two ends of the scaffold that whenever assembles are connected and fixed, whenever the vertical rod fixed point is no less than up and down respectively a bit in putting on airs, the fixed point of every group of shelf is no less than 4 points, scaffold is fixed on firmly by general part on the facade of building, and this moment, shelf just can be used for the construction of building.

When the last layer building structure construction is finished, in the time of scaffold need being promoted first floor height continuation use, earlier in the structural preformed hole of last layer, install general part, the general part that again guide rail is fixed in last layer descends on the general part of one deck with it, and sliding part and guide rail are joined, again vertical rod in sliding part and the scaffold is fixed, again jack is hung on this moment on the suspension ring at top of guide rail, with the chain of jack hook (lower draw-bar) hook on the suspension ring of sliding part bottom or directly be hooked on the rod member of bottom shelf, tensioning this moment jack, remove connecting between general part and the shelf again, slowly spurring jack promotes, shelf just rises along guide rail and under the tension that makes progress of jack slowly by sliding part, after shelf promotes the first floor height, the general part of last layer and its lower floor is all fixed with the vertical rod of shelf, this moment just dismountable jack, sliding part and guide rail, take in another lifting of organizing shelf and use, this group shelf reverts to the state before promoting again, the position of the shelf first floor that raise just, said process repeatedly, scaffold just can constantly raise, in like manner, shelf also can constantly descend, and just the program of program that descends and rising is opposite.

The utility model also can adopt electronic mode to carry out lifting, as replacing jack to carry out lifting with small-sized low speed winch; One from top to bottom elongated tooth bar and for example also can be installed on the guide rail of rigidity, one gear is installed on sliding part, wheel and rack is meshing, gear links to each other with motor with deceleration device again, like this when motor energising rotation, by deceleration device driven gear rotation, gear just can rise or descend by the tooth bar on guide rail, thus drive sliding part and shelf rise or descend.
