Consult accompanying drawing, the system of this most preferred embodiment of the present invention comprises and a plurality ofly is positioned at and is fixed in supporting frame 10 on the roof 12a by braced structures 11, these supporting frames 10 separated by a certain interval around the top of building 12 and stretching out in above the building parapet 12b around the building cantilever, this building is the tier building with a plurality of floors 13, system of the present invention is used for keeping in repair around the building, refreshes or changes surface layer usefulness.Supporting frame 10 comprise a pair of vertically separately push rod or the platform 14 and 15 of jack supporting, being connected on the following platform 14 and extending through top platform 15 vertically upward of push rod or jack 16 than the lower end.Push rod or jack 16 can be international patent application NO, disclosed in OCT/AV90/00042 number by electric motor driven jackscrew, it drives the top frame 17 of its upper end, along with jack flexible, framework 17 is raised and descend.Suspending many complete elongated suspension elements on the top frame 17 in midair, these suspension elements are be in line the suspension pipe fitting 18 that shape down extends along the building surrounded surface and horizontal planes below constituting successively of headtotail.The complete suspension pipe fitting 18 of these shapes that are in line have the working platform 21 that a plurality of vertical direction are provided with at interval than the lower end, to support the operator building external surface is keeped in repair, refresh or change surface layer etc.Working platform 21 extends between the complete suspension pipe fitting with connecting, thereby the continuous platform around the building surrounded surface is provided.
Leave one side of building surrounded surface on working platform, be provided with the breast board 22 of protection operator safety, by the buffer stopper that platform structure is being supported, slide block or roller bearing 23 are pressed on the building external surface, and platform structure and building external surface are separated.
Jack 16 keeps strokes it by central controller controls.It is in upper frame 17 is raised to the supporting frame 10 that is fixed on roof, and this framework 10 provides jack passage in the running, for example: to accessory and other in addition parts placement and withdraw from etc.Framework 10 is suitable for being supported on and is connected to independently on the building.As directed form, this platform can be crossed over big distance between pipe fitting, and a few thing table top can be supported by this continuous structure.Working platform is made around can whole relatively building continuous, also can be only limited to make at a certain isolated area continuous ,-depend on each building surface.In addition, these continuous multilayer platforms also can be made vertically at the position of selecting and be staggered, to adapt to condition of work or labour's best configuration.Native system is flexibly, and a lot of selectable schemes are arranged on the continuation mode of platform, and they depend on required support and constraints.
Enter the working platform district, can also can enter by people and material are used elevator lifting in the building outside by the braced structures on the roof 11.The hoist of these buildings outside can be at an easy rate by/enter the working platform district.Regulate its height gradually to adapt to the variation of working platform horizontal plane.In addition, can utilize the elevator of outside crane or building inside to enter platform area, also can enter platform area from window or balcony.
For firm more and balance, can be between the inner edge of supporting frame 10 and parapet 12b and framework 10 and parapet 12b top between connect respectively support 24 and 24 ', simultaneously, the framework 25 that has balance weight can be suspended in the inboard of supporting frame.
When native system in when operation, platform 21 can rise or descend from the roof segmentation from terrestrial segment.
Two kinds of disposable original positions describing native system are comparatively difficult, and existing process toward decline is described from roof.
Enough complete suspension pipe fittings 18 are connected on the upper frame 17, and the platform structure that contains platform 21 is extended downwards.
Then, in building corner, this platform structure is connected in together.
After this, rising or descend by the stage of this system no longer needs to use outside crane, in case of necessity, just at the duration of work of native system, uses crane to transport material or transport material from working platform toward working platform.When removing native system, need use outside crane once more.
And even the dismounting of native system lower part will be carried out on the ground-carry out on the overcoat of building more than the ground, pass in and out at the building bottom to allow people.Then, need remove the remainder of system with outside crane.At first the suspension pipe fitting be must little by little remove, jack and the framework that is positioned at roof then removed again.
Be used for load is delivered to from suspension pipe fitting 18 advantageous device of supporting frame 10 or top frame 17, be adopt have 2 shear pins around support rack, each shear pin is a double shear, at jack supporting platform 14 or 15 places, load automatically and safely passes to suspension pipe fitting 18 and passes from hanging pipe fitting 18.
When laying down the shear pin 19 at platform 15 places, jack 16 stretches out and jacking top frame 17 makes platform reset (as shown in Figure 3).After this, connect standby suspension pipe fitting 18, their lower end is connected on original complete pipe fitting 18, at platform 15 places, their upper end is connected on the top frame 17 by shear pin 19.Throw off the shear pin 19 between the suspension pipe fitting at platform 14 places then.Jack 16 withdrawals are to fall complete suspension pipe fitting, and platform structure drops to following position, as shown in Figure 4.Repeat this operation sequence, the working platform structure is little by little descended along the building surrounded surface,, refresh (new surface layer 20) or similar operation so that in a period of time, keep in repair.
Operation sequence can some modes of conversion.But in every kind of situation, all must contain and make load be delivered to the device of supporting frame 10 from jack.Simultaneously, jack stretches out and standby suspension pipe fitting 18 is added and connects, and then, working platform is structural segmented to move down in order to make, and load transfers back on the jack from supporting frame conversely.The spacing that is equivalent to platform 14 and platform 15 is moved in segmentation in the aforesaid operations, and consistent with the required segmentation mobile phase of working platform structure.
A mapping mode of above operation is described below, rethinks change system operating position, shear pin 19 and the platform structure this position of operation on being arranged on platform 14 sets about carrying out.This platform structure is suspended on the supporting frame 10 on the roof, and still is connected with jack with top frame 17 by hanging pipe fitting 18.Just in time on platform 14, this complete suspension pipe fitting and top hang pipe fitting throws off, and jack freely stretches out for 16 this moments, hangs pipe fitting to promote top frame 17 and top, leaves other following complete suspension pipe fitting.By the standby suspension pipe fitting of adjunction between platform 14 and platform 15, top frame is received on the following complete hanging tube spare again.Adjunction just in time is on the platform 15 and under the platform 14.Jack stretches out then, is enough to bear the weight of the complete suspension pipe fitting of platform structure.The shear pin that hangs on the pipe fitting is drawn off at platform 14 places, so jack is retracted to top layer.At platform 14 places, support shear pin 19 to be connected to again and hang on the pipe fitting that then, at platform 14 places, jack is withdrawn slightly, so that load is communicated on the supporting frame.
The various conversion scheme of operating process respectively have pluses and minuses, but the basic principle of every kind of scheme is identical.
According to the foregoing description of native system, with respect to prior art, the advantage in the operation of native system now is described in further detail.
Because control is on limited and discrete suspension hoist point, therefore, can be quite accurate, particularly use the electric screw-jacks that discloses in the above-mentioned international patent application, the uniformity of control operation can make this working platform structure all around promote synchronously.In all operating, the platform structure on each face of building is joined together in the corner of building.Therefore, the stability of platform is provided.
From above description to native system as seen, native system is easy to be applicable to the plane geometric shape of various buildings, similarly, by the position of mobile jack on the supporting frame at building top, also can be adapted to the limited variation of a vertical surface of building or several vertical surface.This moving in the building maintenance process needs, and can for example adjust the platform of the one-tenth ranks of corner interfaces by means of using outside crane.
In addition, except during jacking between two horizontal planes, the weight of platform structure is directly born by the supporting frame that is fixed on the building.In fact, native system is static in the most of the time, does not need to consider dynamic load, only during jacking is moved, just will consider dynamic load and the minimizing of the elevating capacity that caused by it.At this moment, can be by suitable Position Control and the dynamic load of handling in the minimizing system.
