Description
Technical field
The present invention relates to a kind of civil engineering means for fastening scaffolding.
Background technology
In Bases in High Building Construction and Reinforced Concrete Bridge process of construction, scaffold is indispensable technical equipment in construction, for high-rise frame civil high-rise buildings, it is pre-buried one section of connecting rod when the cast-in-place concrete structure of certain layer, reach requirement of strength after concrete setting after, just upwards continue erecting scaffold at these pre-buried connecting rods by the fastener of scaffold, until the top layer of building.Then, after building successively completes outer finishing west downwards, then successively scaffold is dismantled.Its weak point: it is not firm to connect between each connecting rod, causes the scaffold insufficient strength of top, and this can bring loss to user.
Summary of the invention
It is simple that the technical problem to be solved in the present invention is to provide a kind of structure, uses, easy for installation, simple to operate, laborsaving, to be connected firmly, reliably, convenient later maintenance, cost is low, applied widely, long service life, has the civil engineering means for fastening scaffolding of safe and reliable effect.
For solving the problem, the present invention adopts following technical scheme:
A kind of civil engineering means for fastening scaffolding, comprise head rod and the second connecting rod, and the jam nut be arranged on head rod, and the fixed head be arranged on the second connecting rod, described head rod is connected with the second connecting rod, described head rod extends in the second connecting rod, described second connecting rod is provided with the antitorque wing, the described antitorque wing runs through head rod and the second connecting rod is arranged, described jam nut is fixedly mounted on head rod, described jam nut is provided with safety screw, the screw hole matched with described safety screw is provided with in described fixed head.
As preferred technical scheme, described head rod is provided with the first external screw thread, described second connecting rod is provided with the first internal thread matched with described first external screw thread, be provided with the second internal thread in described jam nut, described second connecting rod is provided with the second external screw thread matched with described second internal thread.
As preferred technical scheme, described head rod, the second connecting rod, jam nut and fixed head external surface are equipped with one deck anti-corrosion layer.
As preferred technical scheme, described first external screw thread and the first internal thread and the threaded engagement between the second internal thread and the second external screw thread all adopt interference fit.
The beneficial effect of a kind of civil engineering means for fastening scaffolding of the present invention is: during use, matched by the first set external screw thread and the first internal thread, make head rod and the second connecting rod compact siro spinning technology, by set jam nut, add the connection reliability between head rod and the second connecting rod, and matched with fixed head by safety screw, can prevent jam nut from occurring loosening phenomenon.Its structure is simple, uses, easy for installation, simple to operate, laborsaving, is connected firmly, reliably, convenient later maintenance, cost is low, applied widely, long service life, has safe and reliable effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of civil engineering means for fastening scaffolding of the present invention;
Fig. 2 is the partial enlarged drawing of a kind of civil engineering means for fastening scaffolding of the present invention.
Detailed description of the invention
Consult a kind of civil engineering means for fastening scaffolding shown in Fig. 1 and Fig. 2, comprise head rod 1 and the second connecting rod 2, and the jam nut 3 be arranged on head rod 1, and the fixed head 4 be arranged on the second connecting rod 2, described head rod 1 is connected with the second connecting rod 2, described head rod 1 extends in the second connecting rod 2, described second connecting rod 2 is provided with the antitorque wing 5, the described antitorque wing 5 runs through head rod 1 and the second connecting rod 2 is arranged, described jam nut 3 is fixedly mounted on head rod 1, described jam nut 3 is provided with safety screw 6, the screw hole (not shown) matched with described safety screw 6 is provided with in described fixed head 4.
Described head rod 1 is provided with the first external screw thread 7, described second connecting rod 2 is provided with the first internal thread 8 matched with described first external screw thread 7, be provided with the second internal thread 9 in described jam nut 3, described second connecting rod 2 is provided with the second external screw thread 10 matched with described second internal thread 9.
Described head rod 1, second connecting rod 2, jam nut 3 and fixed head 4 external surface are equipped with one deck anti-corrosion layer (not shown).
Described first external screw thread 7 and the first internal thread 8 and the threaded engagement between the second internal thread 9 and the second external screw thread 10 all adopt interference fit.
Further, by the set antitorque wing, when dismantling scaffold, between two mutual connecting rods, skidding can be there is not.
The beneficial effect of a kind of civil engineering means for fastening scaffolding of the present invention is: during use, matched by the first set external screw thread and the first internal thread, make head rod and the second connecting rod compact siro spinning technology, by set jam nut, add the connection reliability between head rod and the second connecting rod, and matched with fixed head by safety screw, can prevent jam nut from occurring loosening phenomenon.Its structure is simple, uses, easy for installation, simple to operate, laborsaving, is connected firmly, reliably, convenient later maintenance, cost is low, applied widely, long service life, has safe and reliable effect.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
