Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Structure of the present utility model as depicted in figs. 1 and 2, comprises scaffold main body and shaped steel Cantilever Beams 1.Shaped steel Cantilever Beams is used for the outside of scaffold body supports at highrise building, one end of shaped steel Cantilever Beams 1 is arranged on the concrete floor 2 of highrise building by anchoring piece 3, the other end of shaped steel Cantilever Beams stretches out outside highrise building, and is fixedly connected with scaffold main body.
Scaffold main body is made up of some vertical equity bars 4, horizontal quarter butt 6 and vertical rod 5, is connected between vertical equity bar, horizontal quarter butt and vertical rod by connector.The vertical rod of scaffold main body is fixed in the through hole of shaped steel Cantilever Beams outer end.
The structure of anchoring piece 3 as shown in Figure 3, at least two support bars 31 comprising base plate 32, pressing plate 34 and be vertically set on base plate.Wherein base plate 32 is positioned at below concrete floor 2; The bottom plug welding of support bar 31 is on base plate 32, and the top of support bar 31 is stretched out above concrete floor, and is provided with external screw thread, and equipped fastening nut 33; Pressing plate 34 is socketed in support bar 31 top.Support bar height is thickness of concrete floor and shaped steel Cantilever Beams height and adds 150mm again.
Shaped steel Cantilever Beams 1 penetrates in the space of pressing plate, concrete floor and support bar formation, by screwing fastening nut 33, is compressed by shaped steel Cantilever Beams under the effect of pressing plate.In the present embodiment, support bar is provided with two, certainly can also be set to 4,6,8 ..., it is two rows that all support bars are set up in parallel, and shaped steel Cantilever Beams is arranged between support bars, to improve firm performance two.
In the utility model, anchoring piece does not adopt conventional U-shaped reinforcing bar draw ring, overcome the operating worker when concreting and trample the generation that roof steel bar causes U-shaped reinforcing bar draw ring position shift phenomenon, ensure that the pre-buried height of anchoring piece and pre-buried position, make the pore size between shaped steel Cantilever Beams and anchoring piece even, be convenient to fixed installation.
In the present embodiment, shaped steel Cantilever Beams selects i shaped steel, and the outer end of i shaped steel is provided with the through hole of fixing feet hand cradle main body.The base plate of anchoring piece adopts 220mm × 100mm × 8mm steel plate, pressing plate adopts 10mm hassock plate, and support bar adopts diameter of phi 20mm round steel, and two diameter of phi 20mm round steel carry out plug welding with 220mm × 100mm × 8mm steel plate and are connected, ensure after plug welding that bottom is smooth, without protruding steel plate phenomenon.The utility model, for convenience of the dismounting of anchoring piece, is set with sleeve pipe 35 in the middle and lower part of support bar, and sleeve pipe adopts the PVC sleeve pipe of diameter of phi 25mm.
The installation process of the present embodiment is as follows:
First base plate is pre-buried and be fixed on concrete blinding, bottom surface and the template of base plate are adjacent to, then by the PVC casing pipe sleeve of diameter of phi 25mm on diameter of phi 20mm round steel, closely knit with tape-stripping, prevent mortar from entering in sleeve pipe.
Then concreting, installs shaped steel Cantilever Beams after concrete final set.
When shaped steel Cantilever Beams is installed, shaped steel Cantilever Beams is placed between two diameter of phi 20mm round steel, after adjusting position, 10mm hassock sleeve-board is entered on diameter of phi 20mm round steel, two fastening nuts placed by every root diameter of phi 20mm round steel, tightening nuts is fastening, can fix the inner of shaped steel Cantilever Beams.
Finally, in the outer end of shaped steel Cantilever Beams, vertical rod 5 is installed, then vertical equity bar 4 is installed in vertical rod, installation that horizontal quarter butt 6 can complete height scaffolding.
After scaffold is finished using, can first remove scaffold main body, then remove shaped steel Cantilever Beams; Remove the process that namely shaped steel Cantilever Beams process removes anchoring piece, can after slab form be removed, beat the supporting bar top of anchoring piece gently with hand hammer, the base plate of anchoring piece and support bar can drop.First fastening nut is screwed on the external screw thread of supporting bar top before beaing, avoids directly beaing support bar and cause screw thread to be out of shape, affect later stage use.
In the present embodiment, the external thread length that the supporting bar top of anchoring piece is arranged is 150mm, is convenient to regulate according to the thickness of different concrete floors.
