Description of drawings

Fig. 1 is the structural representation of overlength cantilever frame structure of the present invention high-altitude formwork bracing system.

The specific embodiment

The present invention is described in further detail with embodiment with reference to the accompanying drawings below.

Fig. 1 is the structural representation of overlength cantilever frame structure of the present invention high-altitude formwork bracing system, and with reference to Fig. 1, the present invention chooses the tree crown moulding building in certain hotel as case study on implementation.Overlength cantilever frame structure high-altitude formwork bracing system, comprise top support body and bottom support body, above-mentioned bottom support body comprises the shaped steel beam 1 of encorbelmenting, under support shaped steel bracket 2, on draw wire rope 3, following Pin concrete truss 4, the top support body comprises load-bearing support for shuttering 5, outer protective frame 6, last Pin concrete truss 7, shaped steel beam 1 one ends of encorbelmenting are fixed on down Pin concrete truss 4 tops by the beam anchor ring 12 of encorbelmenting and stretch out down Pin concrete truss 4 tops, beam 1 upper surface of encorbelmenting is equipped with multilayer proofing plate 10, the bottom of supportting shaped steel bracket 2 down is fixed on down Pin concrete truss 4 middle parts, the top is fixed on beam 1 bottom of encorbelmenting, under support shaped steel bracket 2 and prolong the beam 1 of encorbelmenting and stretch out direction and tilt from bottom to top, wire rope 3 bottoms are fixed on beam 1 top of encorbelmenting, the top is fixed on Pin concrete truss 7 bottoms, load-bearing support for shuttering 5 tops are fixed on Pin concrete truss 7, the bottom is fixed on the beam 1 of encorbelmenting, outer protective frame 6 is arranged on load-bearing support for shuttering 5 outsides, its top is fixed on Pin concrete truss 7, the bottom is fixed on the beam 1 of encorbelmenting, and flame-retardant fine mesh safety net 60 is overworked in outer protective frame 6 outsides.

For this building, particularly, the beam 1 of encorbelmenting is selected the common 20# i iron of GB for use, chooses 5.8m, inboard anchoring 6.2m.Level interval 1.2m, one-sided 20.Outrigger anchor ring 12 is provided with two, between solid length be no less than 30cm, the first road outrigger anchor ring 12 is located in the side bar scope, the second road outrigger anchor ring 12 sets firmly and is not less than 20 diameter bar dowels and strengthens.

Under support shaped steel bracket 2 and adopt 14# i iron brackets to prop up the top, a position, top is apart from the limit beam 1 outer rim 4.6m that encorbelments, pre-buried 250*300*10 steel plate embedded part is as the bracket buried plate during construction of its bottom, the bracket top arranges the thick end plate of 250*200*10, firm welding up and down.

Wire rope 3 adopts on 2 6*37+17.5mm wire rope (f=1700N/mm2) and draws, pre-buried pair of HPB235*25 round steel draw ring in wire rope and the structural concrete, and diameter 32mm flower basket bolt is regulated length, and wire line shoe is fixed, and every end is no less than 3 wire clips.Every building external corner is set up on two 14mm of the place wire rope and is drawn, the distortion of control bight.
