Abstract
The invention belongs to the field of steel structure buildings, and particularly relates to a bolt ball net rack node. The bolt ball net rack node comprises a steel tube, a conical head, a bolt, a nut and a bolt ball, wherein the conical head is fixed to one end of the steel pipe, the bolt is fixed to the conical head through the nut, and the bolt ball is fixed at the other end of the bolt. The bolt ball net rack node has the advantages that the bolt is exposed, and whether the bolt is screwed to the right place or not can be visually observed; the bolt ball does not need to be cut, and one procedure can be omitted; meanwhile, due to the fact that cutting can make the effective diameter of the bolt decreased, the diameter of the bolt ball can be decreased correspondingly.
Description
Technical field
The invention belongs to steel building field, be specifically related to a kind of bolt sphere grid joint.
Background technology
Bolt-ball net frame due to moulding changeable, and compare other steel work, it designs, make, install very convenient, that uses in large-span space structure is commonplace.With reference to Fig. 1, traditional bolt-ball net frame, mainly comprises following a few part: bolt sphere A1, high-strength bolt A2, sleeve A3, pin A4, conehead or shrouding A5, steel pipe A6.The Path of Force Transfer of its pulling force is: be followed successively by, and steel pipe, conehead or shrouding, high-strength bolt spiral shell head, high-strength bolt screw rod, bolt sphere, the Path of Force Transfer of pressure is: be followed successively by, steel pipe, conehead or shrouding, sleeve, bolt sphere.There is following problem in traditional technology: 1, bolt whether execute be screwed to position be difficult to observation; 2, after component processes, the on-the-spot surplus not having to regulate; 3, cannot by constructing pre-arch camber.
For above-mentioned technical problem, the applicant provides the bolt sphere grid joint after a kind of improvement, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of bolt sphere grid joint, with solve bolt whether execute be screwed to position be difficult to observation; After component processes, on-the-spot do not have the technical problems such as the surplus regulated.
For achieving the above object, the concrete technical scheme that the applicant provides is: a kind of bolt sphere grid joint, comprises steel pipe, conehead, bolt, nuts and bolt ball; Wherein, described conehead is fixed on steel pipe one end, and described bolt is fixed on conehead by described nut, and the other end of described bolt is fixed with described bolt sphere.
Further, described bolt is followed successively by the first screw thread, hexagonal section, the second screw thread from termination to spiral shell head; First reach is 1.4 times of described diameters of bolt, and hexagonal section length is 30mm.
Beneficial effect of the present invention:
1, bolt exposes, and can observe whether bolt is screwed to position intuitively.
2, bolt sphere does not need to cut, and can save and eliminate one step from the process, meanwhile, because cutting can cause bolt effective diameter to reduce, adopt bolt sphere diameter of the present invention correspondingly to reduce.
3, be screwed under spheroid length is greater than the prerequisite of designing requirement at bolt, be screwed into length by adjustment, the fine setting of rod member length can be carried out.
4, be screwed into length by adjusting bolt, the construction arch camber of rack can be realized.
5, owing to eliminating pin, screw rod no longer offers chute, the effective area of bolt is not weakened.
Accompanying drawing explanation
Fig. 1 is the bolt sphere structural representation of conventional art;
Fig. 2 is structural representation of the present invention;
Fig. 3 is bolt drawing of the present invention;
Fig. 4 is rod member factory state schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 2, the present invention comprises: bolt sphere 1, bolt 2, nut 3, conehead 4, steel pipe 5.Wherein, described conehead 4 is fixed on steel pipe 5 one end, and described bolt 2 is fixed on conehead by described nut 3, and the other end of described bolt 2 is fixed with described bolt sphere 1.
Wherein the bolt hole position of bolt sphere 1 does not need to cut, and nut 3 adopts the large hex-head nut of the high strength of standard.
With reference to Fig. 3, bolt 2 is followed successively by the first screw thread, hexagonal section, the second screw thread from termination to spiral shell head.Preferably, the first reach gets 1.4 times of diameters of bolt, and hexagonal section length gets 30mm, and the second reach is got nut thickness and added conehead thickness man two screw thread length.
With reference to Fig. 4, it is the factory state of rod member.
During installation, first bolt is screwed into bolt sphere, being screwed into length is the 1.1-1.4 times of diameter of bolt, and require to determine according to adjustment or arch camber, the screw thread length according to exposing after being screwed into judges whether be screwed into length meets the demands.Subsequently nut is screwed onto the second screw position, until expose two screw threads, shows to execute to be screwed to position.
Claims (2)
1. a bolt sphere grid joint, is characterized in that: comprise steel pipe, conehead, bolt, nuts and bolt ball; Wherein, described conehead is fixed on steel pipe one end, and described bolt is fixed on conehead by described nut, and the other end of described bolt is fixed with described bolt sphere.
2. a kind of bolt sphere grid joint according to claim 1, is characterized in that: described bolt is followed successively by the first screw thread, hexagonal section, the second screw thread from termination to spiral shell head; First reach is 1.4 times of described diameters of bolt, and hexagonal section length is 30mm.
