Abstract
The utility model proposes a kind of high-strength bolt used for steel net frame bolt ball node, belongs to Elements of Space Grid Truss bolt technical field.The high-strength bolt includes：Bolt body, including：Bolt head and screw rod, the end of screw rod are provided with screw thread, and the root of screw rod is polygon prism；One side of the root of screw rod is provided with hole；Sleeve, it is set on screw rod, the shape of the inwall of sleeve is consistent with the shape of the root of screw rod；The wall of sleeve is provided with through hole, and when sleeve is located at the root of screw rod, through hole is corresponding with hole.The utility model changes traditional pattern that transmission moment of torsion is used as using screw, six prisms of its screw root play a part of to transmit rotation torque, reliablely and stablely transferred torque to by sleeve in six rib high-strength screw rods, fundamentally prevented the generation of false stubborn phenomenon；And it can judge whether screw rod is all screwed into grid structure with bolt-sphere joints with simple, intuitive.
Description
Technical field
Elements of Space Grid Truss bolt technical field is the utility model is related to, particularly relates to a kind of Elements of Space Grid Truss bolted spherical node high intensity
Bolt.
Background technology
At present, grid structure with bolt-sphere joints, one end of every rod member only have a high-strength bolt to be connected with bolted spherical node.
In the installation process of grid structure with bolt-sphere joints, former high-strength bolt is cylinder due to the root on the inside of its sleeve with high-strength bolt
Shape, only transmits moment of torsion by screw connecting the two, and screw can not transmit moment of torsion easily by cutting, vacation occurs and tighten phenomenon, meeting
Grid structure with bolt-sphere joints overall security is hidden some dangers for.In addition, also can not the discrimination bolt of simple, intuitive whether be all screwed into
In bolt sphere.
Utility model content
To solve above the deficiencies in the prior art, the utility model proposes a kind of Elements of Space Grid Truss bolted spherical node high intensity
Bolt.
What the technical solution of the utility model was realized in：
A kind of high-strength bolt used for steel net frame bolt ball node, including：Bolt body, including：Bolt head and screw rod, screw rod
End be provided with screw thread, the root of screw rod is polygon prism；One side of the root of screw rod is provided with hole；Sleeve, it is set in spiral shell
On bar, the shape of the inwall of sleeve is consistent with the shape of the root of screw rod；The wall of sleeve is provided with through hole, when screw rod is all screwed into
When in grid structure with bolt-sphere joints, through hole is corresponding with hole.
As further improvement of the utility model, the root of screw rod is six prisms or eight prisms.
As further improvement of the utility model, in addition to：Screw, the inwall of through hole are provided with what is be engaged with screw
Screw thread.
As further improvement of the utility model, the length of screw thread is equal to through hole and the total depth in hole on screw.
As further improvement of the utility model, the profile of sleeve is six prisms or eight prisms.
The utility model changes traditional using screw as the pattern for transmitting moment of torsion, the six prisms biography of its screw root
The effect of rotation torque is passed, is reliablely and stablely transferred torque to by sleeve in six rib high-strength screw rods, fundamentally prevented
The generation of false stubborn phenomenon；And it can judge whether screw rod is all screwed into grid structure with bolt-sphere joints with simple, intuitive.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model bolt body；
Fig. 2 is the sectional view of A-A in Fig. 1；
Fig. 3 is the structural representation of embodiment middle sleeve；
Fig. 4 is the left view of view shown in Fig. 3；
Fig. 5 is the structural representation of screw in embodiment；
Fig. 6 is the left view of view shown in Fig. 5.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As Figure 1-4, it is the structural representation of high-strength bolt used for steel net frame bolt ball node in embodiment.
High-strength bolt used for steel net frame bolt ball node in embodiment, including：Bolt body and sleeve, bolt body bag
Include：Bolt head 1 and screw rod, the end 2 of screw rod are provided with screw thread, and the root 3 of screw rod is polygon prism；One side of the root 3 of screw rod
Face is provided with hole 4；Sleeve 5 is set on screw rod, and the shape of the inwall of sleeve 5 is consistent with the shape of the root 3 of screw rod；Sleeve 5
Wall be provided with through hole 6, when screw rod is all screwed into grid structure with bolt-sphere joints, through hole 6 is corresponding with hole 4.It is by range estimation
Can intuitive judgment screw rod whether be all screwed into grid structure with bolt-sphere joints.
In view of current practical application, it is preferable that the root 3 of screw rod is six prisms or eight prisms.
As it can be seen in figures 5 and 6, the structural representation for screw in embodiment.
High-strength bolt used for steel net frame bolt ball node in embodiment, in addition to：Screw 7, the inwall of through hole 6 be provided with
The screw thread that screw 7 is engaged.The length being screwed into according to screw 7, judges whether screw rod is all screwed into grid structure with bolt-sphere joints：When
When screw rod is all screwed into grid structure with bolt-sphere joints, the length that screw 7 is screwed into is equal to through hole 6 and the total depth in hole 4.In addition,
During being positioned at the bottom of grid structure with bolt-sphere joints or the mounting hole of side, screw 7 is screwed into through hole 6, to prevent
Screw rod is fallen into rack bar before being screwed into grid structure with bolt-sphere joints, inconvenience installation.
In order to which more whether intuitive judgment screw rod is all screwed into grid structure with bolt-sphere joints, it is preferable that screw thread on screw
Length is equal to through hole 6 and the total depth in hole 4.
Preferably, the profile of sleeve 5 is six prisms or eight prisms.
The installation of conventional bolt ball node rack, it is screw transmission by sleeve that high-strength bolt, which is screwed into bolt sphere,
Moment of torsion no longer transmits moment of torsion on screw rod, and after using six rib high-strength bolts by trip bolt, but direct by sleeve
Transmit torque on screw rod, in the absence of the situation for cutting screw, fundamentally prevented the generation of false stubborn phenomenon so that bolt
Ball node rack overall security is ensured, while installs the behaviour to provide convenience for the splicing of grid structure with bolt-sphere joints
Make, reduce installation measure cost.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
