Description
Technical field
The utility model relates to the construction installation in a kind of civil engineering, is specifically a kind of scaffold wall connecting piece.
Background technology
Scaffold wall connecting piece is the component of the body of wall of connecting pin hand cradle and building.The scaffold wall connecting piece of prior art comprises the joint steel pipe of a vertical embedded steel tube and a transverse direction, in the concrete that the lower end of embedded steel tube is embedded in body of wall crossbeam, the upper surface of crossbeam is protruded in embedded steel tube upper end, the inner of joint steel pipe is fixed by the upper end snapping of fastener and embedded steel tube, and the outer end of joint steel pipe is fixed by the pole steel tube snapping of fastener and scaffold.
The construction method of the scaffold wall connecting piece of prior art is, before the crossbeam concrete of building body of wall, by the reinforcing cage colligation of the lower end of embedded steel tube and crossbeam, then crossbeam concrete is built by pre-buried for embedded steel tube lower end anchoring, set up scaffold again, and with fastener the inner of joint steel pipe and embedded steel tube upper end snapping fixed and fix with the pole steel tube snapping of fastener by joint steel pipe outer end and scaffold.
There is following defect in the scaffold wall connecting piece of prior art: first, and the partial volume that embedded steel tube is embedded in crossbeam concrete is comparatively large, can produce and destroy, reduce mechanical property and the supporting capacity of crossbeam to beam structure; Secondly, embedded steel tube is subject to shearing and the moment of flexure of the radial direction of scaffold simultaneously, its stressing conditions is complicated, and the mechanical property of steel pipe mainly anti-axial tension instead of anti-radial shear and moment of flexure, therefore the mechanical property of steel pipe can not be given full play to, steel pipe easily bends distortion, and the intensity of total is undesirable; Again, this structure needs at joint steel pipe two ends difference snapping two groups of fasteners, and fastener snapping installation process is cumbersome, and the labour intensity of two groups of fastener snappings is very large, therefore adds cost of labor; And the lower end of embedded steel tube is pre-buried to be anchored in crossbeam concrete, to be difficult to remove, therefore during dismounting, embedded steel tube can only be cut off, therefore unloading process to be cumbersome, and by the embedded steel tube curtailment cut off, to be difficult to again utilize, can only to scrap; Thirdly, foot rest is generally shelved on joint steel pipe to form platform by people, but there is gap between foot rest and beam surface upper, foreign material on crossbeam are also easy to drop from this gap, namely there is the hidden danger of falling object from high altitude, therefore need to block this gap further, shutoff process adds operation construction sequence, trouble effort; Again because the later stage needs to continue from crossbeam upwards masonry panel toward contact, and, due to the existence of wall-connecting piece on crossbeam, this body of wall can only be built by laying bricks or stones at twice, specifically, first build the body of wall in non-wall-connecting piece region by laying bricks or stones, and reserve the gap of accommodating wall-connecting piece, build the body of wall in wall-connecting piece region after waiting scaffold and wall-connecting piece to dismantle again by laying bricks or stones, like this, the step of walling is many, workload is large, complicated operation, and secondary is built by laying bricks or stones and be there is leakage hidden trouble.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of to wall transversal girder construction destroy little, intensity is desirable, save fastener, scaffold wall connecting piece that convenient install operation process, for convenience detach and material can recycle, avoid falling object from high altitude, stop leakage hidden trouble.
Technical solution of the present utility model is, a kind of scaffold wall connecting piece is provided, it comprises joint steel pipe, it also comprises L shape embedded bar, the sleeve of both ends open, the end plate of screw rod and band centre bore, the major part of L shape embedded bar is embedded in the crossbeam concrete on body of wall, the outer end of the horizontal bar of L shape embedded bar stretches out beam outer surface and horizontal bar outer end is provided with external screw thread, the internal thread hole of horizontal bar outer end and sleeve inner end is spirally connected, the internal thread hole of sleeve outer end and the inner of screw rod are spirally connected, screw rod outer end is combined with fastening nut, joint steel pipe and end plate are linked on screw rod, joint steel pipe holds out against at beam outer surface through end plate by fastening nut, the pole steel tube snapping of joint steel pipe and scaffold is fixed.
Implement the construction method of scaffold wall connecting piece of the present utility model, its step comprises: the major part of L shape embedded bar to be embedded in during cast crossbeam concrete in crossbeam concrete and to make the outer end of the horizontal bar of L shape embedded bar stretch out beam outer surface, the internal thread hole of sleeve inner end and the outer end of horizontal bar are screwed, screw rod the inner is screwed in the internal thread hole of sleeve outer end, joint steel pipe and end plate are enclosed within screw rod, fastening nut is tightened on screw rod outer end, fastening nut is made through end plate, joint steel pipe to be pressed on the external surface of crossbeam, fastener is utilized to be fixed by the pole steel tube snapping of joint steel pipe and scaffold.
The utility model scaffold wall connecting piece compared with prior art, has the following advantages:
First, a pre-buried steel pipe compared to existing technology, it in crossbeam concrete is only a L shape embedded bar that the utility model is embedded in, and its pre-buried volume is much smaller than the pre-buried volume of prior art, therefore little to the structural deterioration of crossbeam, ensure that mechanical property and the supporting capacity of crossbeam concrete structure itself, and, although this L shape embedded bar volume is little, can be firm with the reinforcing cage colligation in crossbeam concrete, make the bulk strength of this wall-connecting piece large, very firmly; Secondly, embedded steel tube is the pulling force of the axis along steel pipe as the active force that the main element connected is subject to scaffold, therefore can give full play to the mechanical property of this steel pipe, makes the intensity of total desirable, body of wall and scaffold are connected firmly; Again, eliminate the fastener of half during this structure installment, like this, also just reduce half with the labour intensity of fastener snapping, installation process is simple and convenient, time saving and energy saving, saves cost of labor; And unloading process is also simple and convenient, without the need to cutting any parts, only fastener need be untied and sleeve, fastening nut are unscrewed, and the fastening nut of dismantling, screw rod, joint steel pipe, end plate all repetitive cycling can use, and reduce further cost; And, when needing to set up foot rest platform, foot rest is shelved on after on joint steel pipe, the inner of foot rest can touch the external surface of crossbeam, therefore there is not the gap falling thing between the foot rest of prior art and crossbeam, stopped the potential safety hazard of falling object from high altitude, also nature is without the need to plugging gap of taking measures in addition; And, this wall-connecting piece can not epirelief in crossbeam, the body of wall above crossbeam can disposablely be built by laying bricks or stones shaping, without the need to reserving gaps, therefore easy construction, stops leakage hidden trouble.
