The specific embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.
Fig. 1 to Fig. 3 has schematically shown the scaffold wall connecting piece according to a kind of embodiment of the present utility model.
As shown in Figure 1 to Figure 3, in an embodiment of the present utility model, scaffold wall connecting piece comprises: pre-buried bar 10, connector 20, carrier bar 30, wall connecting rod 40, pad 50 and locking member 60.
Wherein, pre-buried bar 10 is that a diameter is 25mm, and length is the reinforcing bar of 1m.The reach that one end end 101 of pre-buried bar 10 is provided with the first external screw thread 1011, the first external screw threads 1011 is 50mm.Pre-buried bar 10 is embedded in fabric structure beam, sheet-pile concrete 1 in advance, and the first external screw thread 1011 of its end 101 to stretch out building wall external, be positioned at insulating layer of external wall 2.Pre-buried bar 10 stretches out the external part of building wall to be smeared with butter, and protects with plastic sheeting.
As shown in Figure 1 to Figure 3, during construction, accurately locate for pre-buried bar 10 by the spacing of 70 of external scaffolding vertical rods and the length of wall connecting rod 40, be embedded in advance in fabric structure, slab column concrete 1, by connector 20, the end 301 of carrier bar 30 is threadedly connected to again the end 101 of pre-buried bar 10, and screws up with a wrench.As shown in Figure 2, the end of pre-buried bar 10 and carrier bar 30 is held out against in the central position of connector 20, prevent that the junction from getting loose.Wall connecting rod 40 is sheathed on outside carrier bar 30, and the one end is butted on insulating layer of external wall.Wall connecting rod 40 outsides are stretched out in the end end 302 that carrier bar 30 is not connected in pre-buried bar 10, the sheathed pad 50 in the end 302 of carrier bar 30, be threaded with the end 302 of carrier bar 30 by locking member 60 again, wall connecting rod 40 tightly supported be located between insulating layer of external wall wall and pad.In above-mentioned, the first external screw thread 1011 is straight thread with 2011 of the first internal threads, the 3rd external screw thread 3021 with 6011 of the second internal threads with 2011 of the first internal threads, the second external screw thread 3011 and is connected.
As shown in Figure 1, during construction, wall connecting rod 40 buckles by cross buckle 90 with scaffold ledger 80 and scaffold upright rod 70, consists of one with carrier bar 30 and the stressed structural system of connector 20.Thus, pre-buried system and scaffold support body are connected to form a stressed framework of integral body, make stressed evenly, improved bearing capacity.During use, 70 of vertical rods, lay pedal on wall connecting rod 40, trample for the constructor.
Scaffold wall connecting piece of the present utility model, by imbed in advance pre-buried bar 10 when the building operations in fabric structure beam, sheet-pile concrete, be connected with pre-buried bar 10 by a carrier bar 30, then scaffold ledger 80 and scaffold upright rod 70 are buckled in carrier bar 30 by cross buckle 90, thereby reach being connected of scaffold and building.Scaffold wall connecting piece of the present utility model is by burying in advance pre-buried bar 10, again carrier bar 30 is threadedly connected to pre-buried bar 10, carrier bar 30 is connected more firm with building, make carrier bar 30 not only have the effect of support, and reduced the lateral displacement of scaffold, play the effect of drawing, improved safety.In addition, be provided with wall connecting rod 40 and locking member 60.Thus, strengthen the supporting capacity of scaffold wall connecting piece by wall connecting rod 40, facilitated simultaneously being connected of scaffold wall connecting piece and scaffold.Simultaneously, locking member 60 has reduced the lateral displacement of scaffold with wall connecting rod 40 and building masonry wall locking, has played the effect of drawing, has improved safety.Pad 50 is set, and pad 50 is set to square block, in the situation that the diameter of locking member 60 less than wall connecting rod 40, makes wall connecting rod 40 be difficult for skidding off outside locking member 60, makes wall-connecting piece 40 and wall connecting tightr, strengthened pulling force.30 of 10, connector 20 and carrier bar 30 and pre-buried bar, locking member 60 and carrier bars all adopt straight thread to connect, and make the connection close and firm, are convenient to simultaneously dismounting, and the operating risk when having avoided welding has ensured that simultaneously insulating layer of external wall avoids destroying.The screw thread line of straight thread is thick, tightens rear affected by vibration littlely, is difficult for looseningly, and tensile strength is high, and is not easy-to-draw bad.
In sum, scaffold wall connecting piece of the present utility model, simple in structure, reduced cost, be convenient to installation and removal.Pre-buriedly imbed under construction pre-buried bar, then carrier bar is threadedly connected to pre-buried bar, make the close and firm more that is connected of scaffold and building object, not only play the effect of support, and reduced the potential safety hazard that lateral displacement brings.Pre-buried system and support body are connected to form a stressed framework of integral body, have improved bearing capacity.Strengthened the security performance of the whole stress system of exterior wall scaffold.Simultaneously do not affect indoor and outdoor and fit up simultaneously, improved efficiency of construction.Need not manually stifled outer wall screw eye of secondary, ensured that insulating layer of external wall avoids destruction.
