Abstract
The utility model discloses a threaded device of a pillar bolt of a scaffold. The threaded device comprises a screw and a bottom support, wherein a first through hole is formed in the screw; threads are arranged on a wall of the first through hole; threads are also arranged on the outer surface of the screw; the bottom support has a symmetric structure and is distributed on two sides of the screw; the bottom support and the screw are integrated; and two ends of the bottom support and the screw form a symmetric arc-shaped structure. The threaded device is provided with the arc threads; the construction speed of a project is increased; dirt is not generated easily in a construction process; a whole structure cannot be damaged; the bottom support has the arc-shaped structure, so that the supporting bolt and a subassembly can be fixed, and cannot drop easily; and the use ratio is increased.
Description
Technical field
The utility model relates to a kind of earthquake structural engineering field, is specifically related to a kind of screw device of scaffold support bolt.
Background technique
Scaffold support bolt is a connection, and what play link effect is exactly the screw thread of bolt, and in scaffold support bolt uses, coarse thread and bolt of serration can be felt some relatively good revolving in construction, and some is more difficult.Existing traditional scaffold support bolt generally adopts trapezoidal thread, easily by concrete or other fouling, causes bolt surface bump injury and is difficult for taking out stains, impact construction dismounting and recycling in construction.
Model utility content
The purpose of this utility model is to provide a kind of circular thread setting that adopts, be conducive to improve the speed of application of engineering, and in work progress, be difficult for producing dirt, avoid overall structure to be unlikely to infringement, collet adopts arc-shaped structure to be provided with and helps stay bolt and the fixing difficult drop-off of assembly, the screw device of the scaffold support bolt of increasing operation rate.
The technical solution of the utility model is, a kind of screw device of scaffold support bolt, the screw device of described scaffold support bolt comprises screw rod and collet, in described screw rod, be provided with the first through hole, on described the first through-hole wall, be provided with screw thread, described screw rod outer surface is provided with screw thread equally, and described collet is that a symmetrical structural distribution is in described screw rod both sides, being structure as a whole of described collet and described screw rod, the two ends of described collet and described screw rod are the arc-shaped structure setting of a symmetry.
In preferred embodiment of the utility model, the screw thread arranging on the first through-hole wall of described screw rod is circular thread.
In preferred embodiment of the utility model, the internal diameter of the first through hole in described screw rod is 13mm.
In preferred embodiment of the utility model, on described collet, the other end of screw rod is provided with a second protruding through hole equally.
In preferred embodiment of the utility model, the internal diameter of described the second through hole is less than the internal diameter of the first through hole.
Described in the utility model is a kind of screw device of scaffold support bolt, the utility model adopts circular thread setting, be conducive to improve the speed of application of engineering, and in work progress, be difficult for producing dirt, avoid overall structure to be unlikely to infringement, collet adopts arc-shaped structure to be provided with and helps stay bolt and the fixing difficult drop-off of assembly, increase operation rate.
Brief description of the drawings
Fig. 1 is the structural representation of the screw device of scaffold support bolt in the utility model one preferred embodiment;
In accompanying drawing, each mark is as follows: 1, screw rod, 2, collet, 3, the first through hole, 4, the second through hole.
Embodiment
Below preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Described in the utility model is a kind of screw device of scaffold support bolt, shown in Figure 1, the screw device of described scaffold support bolt comprises screw rod 1 and collet 2, in described screw rod 1, be provided with the first through hole 3, on described the first through hole 3 walls, be provided with screw thread, described screw rod 1 outer surface is provided with screw thread equally, described collet 2 is that a symmetrical structural distribution is in described screw rod 1 both sides, described collet 1 is structure as a whole with described screw rod 2, and the two ends of described collet 2 and described screw rod 1 are the arc-shaped structure setting of a symmetry.
The screw thread arranging on the first through hole 3 walls of described screw rod 1 is circular thread.
The internal diameter of the first through hole 3 in described screw rod 1 is 13mm.
On described collet 2, the other end of screw rod 1 is provided with a second protruding through hole 4 equally.
The internal diameter of described the second through hole 4 is less than the internal diameter of the first through hole 3.
In the utility model, in the screw device process of making stay bolt, select SS400P material to produce through multi-locating automatic cold forging machine, while opening the first through hole on screw rod, in the first through hole, select the tapping of import screw tap, in scaffold support bolt construction as long as connect the first pupil with screw rod through walls.Because adopting circular thread its thread than general thread few nearly a times, therefore can greatly improve the construction speed of engineering while screw-in, surperficial dirt and screw thread position after easy-clear use are difficult for causing bump injury; Collet is filled after structure in the arc-shaped, make stay bolt and assembly parts difficult drop-off, increase operation rate.
Described in the utility model is a kind of screw device of scaffold support bolt, the utility model adopts circular thread setting, be conducive to improve the speed of application of engineering, and in work progress, be difficult for producing dirt, avoid overall structure to be unlikely to infringement, collet adopts arc-shaped structure to be provided with and helps stay bolt and the fixing difficult drop-off of assembly, increase operation rate.
The foregoing is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
