Abstract
The utility model belongs to the field of a construction member of a building external scaffold, in particular to a pull rod of an external scaffold. The pull rod of the external scaffold comprises an embedded nut, one side of the embedded nut is connected with a short screw rod, the other side of the embedded but is connected with a long screw rod, a casing pipe is arranged on the external wall of the long screw rod, one end of the casing pipe abuts against the embedded nut, and the other end of the casing pipe is fixed on the long screw rod through a gasket and a nut. The pull rod of the external scaffold not only reduces cost but also does not affect construction of a wall space.
Description
Technical field
The utility model belongs to building external scaffolding member field, particularly a kind of external scaffolding pull bar.
Background technology
Scaffold refers to the job site for workman's operation and solves various supports vertical and that horizontal transport is set up.The generic term on building circle refers to be used on the building site the higher place that can't directly construct of exterior wall, interior decoration or floor height.Mainly construct up and down for the constructor or the maintenance of peripheral safety net and high-altitude installation component etc.
The external scaffolding pull bar is a kind of reinforcing scaffold, makes constructor's safer member of constructing.The scaffold pull bar of prior art: pre-buried vertical steel pipe on the floor girder and board of major structure of construction, the vertical rod of external scaffolding is fixedly connected with the vertical steel pipe that is embedded in major structure of construction by horizontal steel tube, and connecting portion adopts cruciform fastening for falsework to fix.
Carefully analyze existing external scaffolding pull bar, be not difficult to find that there is following deficiency in it:
One, the external scaffolding of prior art, because when beginning to assemble, vertically a steel pipe part is embedded in the floor girder and board of agent structure, need to cut with oxygen-acetylene when removing, because a part of steel pipe is still just stayed in the floor girder and board, cost strengthens after the cutting.
Two, the external scaffolding of prior art, because pre-buried vertical steel pipe is positioned at the body of wall position, the size of reserving during therefore to the constructions such as building by laying bricks or stones, whitewash of body of wall is larger, repairs area larger.
In view of this, the inventor develops a kind of external scaffolding pull bar specially, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of external scaffolding pull bar, can reduce cost, do not affect again the construction of metope.
In order to reach above-mentioned purpose, the technical solution of the utility model is:
A kind of external scaffolding pull bar comprises embedded nut, and embedded nut one side is connected with short screw, and opposite side is connected with long bolt, at the long bolt outer wall sleeve pipe is installed, and sleeve pipe one end withstands embedded nut, and the sleeve pipe other end is fixed on the long bolt by packing ring and nut.
As the further setting of such scheme, described short screw is with crotch.
Between described long bolt and the embedded nut for being threaded, between short screw and the embedded nut for being threaded.
The diameter of described long bolt is 14-20mm.
Described embedded nut is detachable embedded nut.
Described sleeve pipe is plastic bushing, and is not only light, and can play antisepsis.
After adopting such scheme, the utility model compared with prior art has the following advantages:
One, convenient disassembly, without the oxygen-acetylene cutting, long bolt, sleeve pipe, nut, packing ring are all reusable, save cost.
Two, do not affect building by laying bricks or stones of body of wall, only the plastering construction of External Wall produces a very little reservation face.
Three, when cruciform fastening for falsework caused because holding capacity transfinites producing slippage between the vertical rod of external scaffolding and the pull bar, pad can play certain barrier effect, has improved security performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of external scaffolding pull bar of the utility model, comprise embedded nut 1, embedded nut 1 one sides are connected with short screw 2, opposite side is connected with long bolt 3, at long bolt 3 outer walls sleeve pipe 4 is installed, sleeve pipe 4 one ends withstand the lateral wall of embedded nut 1, and sleeve pipe 4 other ends are fixed on the long bolt 3 by packing ring 5 and nut 6.Wherein, short screw 2 is with crotch 7.Between long bolt 3 and the embedded nut 1 for being threaded, between short screw 2 and the embedded nut 1 for being threaded.The diameter of long bolt 2 is 14-20mm, and is identical with the diameter of the vertical rod 8 that has general external scaffolding now.Embedded nut 1 is detachable embedded nut.Sleeve pipe 4 is plastic bushing.
When the utility model uses, when building is carried out the construction of flooring beam column, first embedded nut 1 and short screw 2 are connected, pre-buried in flooring beam column 10, long bolt 3 one ends are screwed in the embedded nut 1, then the outer wall at long bolt 3 is nested with sleeve pipe 4 again, then at long bolt 3 other ends that extend to sleeve pipe 4 outsides packing ring 5 and nut 6 is installed, sleeve pipe 4 is fixing, by anchor ear 9 sleeve pipe 4 and long bolt 3 are fixed in the vertical rod 8 at last.
After whole building main body construction is complete, can remove exposing part, reuse.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
