The problem of with bolt sphere and steel pipe connective stability is influenced.
To achieve the above object, the utility model provides the following technical solutions: a kind of Elements of Space Grid Truss bolted spherical node is with high-strength
Bolt, including screw rod and bolt head are spent, the bottom end of the screw rod is fixed with bolt head, is provided with above the outer surface of the screw rod
Locking screw offers strip groove among the outer surface of the screw rod, and the outer surface of the screw rod is socketed with sleeve, the spiral shell
The top of bolt head offers multiple anticreep grooves, and the bottom end of the bolt head offers cross recess.
Preferably, the top diameter of the bolt head is greater than its top diameter, and its base diameter is greater than the diameter of screw rod.
Preferably, there are four the anticreep groove settings, and four anticreep grooves are arranged in " rectangular array shape ".
Preferably, being run through among the outer surface of the sleeve by screw hole has fastening screw.
Preferably, the sleeve is connect with screw flight, and the smooth outer surface of the sleeve.
Preferably, the length of the strip groove is the one third of spiro rod length, and on the inside of the strip groove
Side and lower section are in " arc ".
Compared with prior art, the utility model has the beneficial effects that the high-intensitive spiral shell of this kind of Elements of Space Grid Truss bolted spherical node
Bolt is provided with anticreep groove and bolt head, and the top diameter of bolt head is greater than its base diameter, when in use, staff
Screw rod is run through to one end of steel pipe, and fixes convex block and anticreep groove on the inside of steel pipe, sleeve is then socketed in screw rod
Outer surface, and fastening screw is extended in strip groove through screw hole, finally screw rod and bolt sphere are fixed, after locking
Keep sleeve inconsistent with steel pipe, tie down screw is achieved the purpose that with this, solves and be buckled on the inside of bolt head and can loosen in steel pipe, make
The problem of at security risk and bolt head top diameter and base diameter same affect bolt sphere and steel pipe connective stability.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of high-intensitive spiral shell of Elements of Space Grid Truss bolted spherical node
Bolt, including screw rod 1, anticreep groove 2, bolt head 3, cross recess 4, strip groove 5, locking screw 6, sleeve 7, fastening screw 8
With screw hole 9, the bottom end of the screw rod 1 is fixed with bolt head 3, is provided with locking screw 6 above the outer surface of the screw rod 1,
Strip groove 5 is offered among the outer surface of the screw rod 1, the outer surface of the screw rod 1 is socketed with sleeve 7, the bolt head 3
Top offer multiple anticreep grooves 2, the bottom end of the bolt head 3 offers cross recess 4, the convex block on the inside of steel pipe and anti-
De- groove 2 is fixed, is tightly fastened bolt head 3 with steel pipe.
