Description
Technical field
The utility model 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 problems to be solved in the utility model 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 utility model 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 utility model 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.
