Abstract

The utility model relates to a scaffold for building construction, particularly a hanging scaffold for lifting braced girders, which is characterized in that the outer side of a braced girder is provided with a lifting device; the lower part of the braced girder is connected with a hanger through a connecting piece; the adopts steel bar materials whose diameters are smaller than the diameter of a steel pipe of the braced girder; the hanger not only can reduce weight, but also can save 50 percent of steel materials. The utility model has the advantages of low gravity center and high stability, so can not incline and collapse easily even if carrying out high-rise building construction. The lifting and hanging point of the hanging scaffold for lifting braced girders is arranged on the upper braced girder and the hanging scaffold for lifting braced girders appears plumb-shaped when lifting. Taking no account of the guiding of a guide rack, the lifting of the hanging scaffold for lifting braced girders is very safe. The utility model also has the advantages of simple structure, convenient installation and disassembly, and 40 percent of labor cost saving.

Description

Promote the trusses working platform

The utility model relates to the scaffold that a kind of building operations is used, and especially promotes the trusses working platform.

At present, used scaffold all is the outriggers that are barricaded as by the steel pipe that interweaves in length and breadth in building operations.This scaffold is not only heavy, and installation, demolition inconvenience, and cost height are used time-consuming.Particularly when carrying out high-building construction, the center of gravity of scaffold is higher, once run into external resistance, scaffold tilts and collapses easily, brings dangerous greatly to building operations.In addition, the lifting suspension centre of this class scaffold is in the outrigger bottom, because center of gravity is higher, must consider the guide rail guiding in lifting process, otherwise, can not guarantee the outrigger security improvement.

The purpose of this utility model provides a kind of lifting trusses working platform.By suspension bracket is set below trusses, make the scaffold center of gravity on the low side; Be arranged on the upper spar promoting suspension centre, make scaffold when promoting, be the vertical shape, thereby guarantee security improvement and safe construction.

Concrete scheme of the present utility model is: comprise the steel pipe trusses that interweaves in length and breadth, it is characterized in that, in the outside of trusses lifting appliance is installed, be connected with suspension bracket through connecting piece below trusses.

Because the utility model is provided with suspension bracket below trusses, this suspension bracket hangs on the trusses as a vertical especially, has not only increased the lifting steadiness of scaffold, and the center of gravity of scaffold is reduced.When high-building construction promoted, even if external resistance is arranged, scaffold can not tilt and collapse yet.In addition, lifting appliance (promptly promoting suspension centre) is installed on the upper spar, and it is higher than the center of gravity of scaffold, when lifting appliance upwards promotes, promotes suspension centre and is the vertical shape, need not consider guide rail guiding problem, can carry out security improvement.

Adopt such scheme, simple in structure, it alleviates 50% from anharmonic ratio raw steel pipe support, and cost is low, and installation, demolition are conveniently; The scaffold center of gravity is on the low side, and is safe and reliable; Promote suspension centre and be located on the upper spar, promote convenient and safe.

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

Figure 11, Figure 13, Figure 15, Figure 17, Figure 19, Figure 21 are other several embodiment that connecting piece 3 links trusses 1 and suspension bracket 4.

Figure 12 is the left view of Figure 11, and Figure 14 is the left view of Figure 13, and Figure 16 is the left view of Figure 15, and Figure 18 is the left view of Figure 17, and Figure 20 is the left view of Figure 19, and Figure 22 is the left view of Figure 21.

As seen from Figure 1, Figure 2: the utility model is made up of trusses 1, lifting appliance 2, connecting piece 3 and suspension bracket 4.Wherein trusses 1 usefulness φ 48 steel pipes interweave in length and breadth the overlap joint form.Suspension bracket 4 is taken the reinforcing bar material of diameter less than φ 48, and the general scaffold of weight ratio of the present utility model like this is in light weight, and saves steel, and cost is low.Annexation of the present utility model is: in the outside of trusses 1 lifting appliance 2 is installed, is connected with suspension bracket 4 through connecting piece 3 below trusses 1.Suspension bracket 4 is made up of less than the leger 8 and the fixed bar 10 of montant 5, cross bar 6, foot rest 7 and the suspension bracket bottom of trusses bar diameter; Wherein the montant 5 of suspension bracket 4 bottoms is suspension ring, and it and leger 8 are hung binding, and fixed bar 9 is cemented on leger 8 and the building 10, and foot rest 7 is placed on leger 8 and each cross bar 6.Can find out from Fig. 5, Fig. 6, Fig. 7, Fig. 8: each is perpendicular at the middle part of suspension bracket 4, link by steel plate and bolt between the cross bar.In the time of need increasing suspension bracket 4, desirable lower steel plate and bolt increase perpendicular, cross bar, with steel plate and bolt each bar are linked up again then.By Fig. 1, Fig. 3, shown in Figure 4, link by connecting piece 3 and trusses 1 at suspension bracket 4 tops.

By Fig. 3 and Fig. 4 and Figure 19 and Figure 20 as can be known: connecting piece 3 is suspension ring connecting pieces.But the top montant 5 of the connecting piece suspension bracket 4 among Figure 19 and Figure 20 wherein.

By Figure 13, Figure 14 as can be known: connecting piece 3 is suspension hook connecting pieces, but the top montant 5 of this connecting piece suspension bracket 4.

By Figure 11 and Figure 12 and Figure 17 and Figure 18 as can be known: connecting piece 3 is boatswain chair connecting pieces.

By Figure 15 and shown in Figure 16: connect bolt connecting piece of connecting piece 3.

By Figure 21 and shown in Figure 22: connecting piece 3 is anchor ear connecting piece also.

This shows: connecting piece 3 is suspension ring, suspension hook, boatswain chair connecting piece or bolt connecting piece or anchor ear connecting piece.
