Description
Technical field
The utility model is related to steel structure technology field, more specifically to a kind of for grid structure with bolt-sphere joints
Straight tube component.
Background technology
Grid structure is broadly divided into：Two kinds of weld ball-node grid structure and grid structure with bolt-sphere joints.Grid structure with bolt-sphere joints its
Processing capacity is larger in element factory, and in-site installation is convenient, and tight suitable for the live duration, execution conditions, electricity consumption are restricted, rack
Complex-shaped, rod piece location difficulty polymorphic structure.
Weld ball-node grid structure haves the shortcomings that installation, to dismantle no grid structure with bolt-sphere joints convenient, therefore is actually answering
It is mostly in the majority with grid structure with bolt-sphere joints in, but there is also some defects for existing bolt-ball net frame structure, such as in practical behaviour
It is poor that there is also fastnesses in actual use after discovery web member or chord member are connected by high-strength bolt in work, is easy to loosen
The phenomenon that, if can then be affected to entire grid structure for generating to loosen at large-scale steel structure rack one, directly result in
Safety accident.
Existing the day for announcing is on December 26th, 2014 application No. is the patent of CN201410831452.4, and patent name is：
Connecting rod for bolted spherical node Elements of Space Grid Truss.This application is by rack connecting tube, bolted spherical node Connecting jont and bolt sphere
It constitutes, the bolted spherical node Connecting jont is made of bolt, sealing plate conehead and sleeve, in the bolt sphere there are two settings
Above internal thread connecting hole, the internal thread connecting hole coordinate with the bolt, the rack connecting tube with it is described
Sealing plate conehead be fixedly connected, the tail end of the bolt is co-axially located in the sealing plate conehead, in the bolt
The sealing plate conehead is stretched out in section and front end, and the sleeve is set in the stage casing of the bolt, the front end of the bolt
It is connect with the bolt sphere by screw thread, the rack connecting tube is made of a steel plastic composite structure pipe, the steel
The end of plastic composite structure pipe is connect by helicitic texture with the sealing plate conehead.It can between the sleeve and bolt of this application
It is slided along pin is opposite, into connecting tube, sidesway can make bolt retract in sleeve, and sidesway can be such that bolt stretches out to outside connecting tube
It is easily installed in bolt sphere.There are two types of the case where bolt retraction sleeve, and one is the screw rods of bolt to be fully retracted sleeve, this
For structure in the case where bolt and sleeve not yet install connection, sleeve has protective effect to the threaded shank of bolt, but when needs
When bolt is connect with bolt sphere, bolt can not voluntarily stretch out sleeve, and the end of bolt is taken out to presence out of sleeve
It is greatly difficult；Another kind is the screw portion retraction sleeve of bolt, and the end of bolt is exposed outside sleeve in this case, when need
When installing, the threaded shank of bolt is extracted sleeve by the end for catching hold of bolt, but in this case, sleeve is to bolt
The protective effect of threaded portion is limited, and the end of bolt is easy corrosion or is damaged by percussion.
