Description
Technical field
The utility model is a kind of node, particularly a kind of bowl type bolt hollow ball node that is used for space lattice steel work technical field.
Background technology
The space structure is stressed rationally because of it in the prior art, rigidity is big, in light weight, cost is low, form of structure is novel abundant, lively, can give prominence to advantages such as human art creativity, has become the important component part in the modern life, be subjected to the attention of countries in the world construction sector and research department, and obtained developing rapidly.
In space structures, spatial mesh structure (rack and net shell etc.) is used very widely with light and handy, easy for installation the obtaining in the roof structure system of its deadweight, and it is a kind of space bar structure that is formed by connecting by node system.The node of spatial mesh structure is a primary structure member important in the structural system, plays a part to connect the junction rod member, transmits the roofing load and hangs load, and the rod member that intersects at a node usually has 6 at least, and many reaches 13.The number of nodes of spatial mesh structure is many, and the node steel using amount accounts for total rod member steel using amount
～
, therefore rational node system all has a direct impact degree of safety, fabrication and installation, programming, steel using amount index and the construction costs of structure.
In the spatial mesh structure of China, bolted spherical node and welded hollow spherical joints are present main joint forms.Bolted spherical node mainly is applicable to bilayer or multilayer space rod member system, and it is to be made of bolt sphere, high-strength bolt, Hexagonal jacket, trip bolt and conehead or shrouding.The bolted spherical node system has obtained using very widely in China, and its advantage is that manufacture craft is simple, and is on-the-spot easy for installation; But also have many shortcomings simultaneously, maximum problem is when adopting manual wrench to be screwed into, and is difficult to measure the degree of depth that high-strength bolt is screwed into bolt sphere, so the reliability that node connects relies on installation quality greatly.Because the construction features of existing bolted spherical node system check that whether high-strength bolt reaches the method that is screwed into the degree of depth is to clap the X-ray sheet to detect, this method cost is too high, if all detect, cost is very high.
Welded hollow spherical joints is applicable to individual layer and double-deck multilayer space bar structure, this joint system is that steel pipe and prefabricated hollow ball directly are welded at the construction field (site), its advantage is that its rigidity is big than bolted spherical node, but, the field Welding workload of this joint system is very big, and is all-position welding, and the welding difficulty is bigger, the diameter of ball is big more a lot of than caliber simultaneously, and this also becomes an architectural shortcoming.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of bowl type bolt hollow ball node that is used in bilayer or multi-layer net structure is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of bowl type bolt hollow ball node, comprise hollow ball, one sidewall of hollow ball is provided with opening part, described hollow ball is provided with connecting hole and chord member hole, chord member is fixed with chord member in the hole, be fixed with the connection rod member in the connecting hole, described connection rod member comprises rod member, conehead and pad, rod member, conehead, pad and hollow ball are complementary by bolt and fixedly connected, the connecting hole in the hollow ball is crossed in the bolt cross-under, be respectively equipped with the chord member hole on four quadrants of described hollow ball sidewall, the end face of hollow ball is provided with one and more than one connection rod member.Novel bowl type bolt hollow ball node system is applicable to bilayer and multi-layer net structure, and the theory of computation of its structure design is carried out according to spatial link finite element method, and tension bearing capacity and compression bearing are mainly considered in the design of hollow ball node.Novel bowl type bolt hollow ball node is compared with existing bolted spherical node, has lacked sleeve and pin, the substitute is the arc pad, replaces medicine ball with hollow ball simultaneously, and high-strength bolt passes hollow ball ball wall and is connected with conehead with the arc pad.This structure will be easy to check whether high-strength bolt is screwed to the position, and it has not only avoided former bolted spherical node system to be difficult to measure the drawback that high-strength bolt is screwed into the degree of depth, and also light than former bolted spherical node on steel using amount.Novel bowl type bolt hollow ball node is compared with welded spherical node, and it has avoided a large amount of, highly difficult field Welding, therefore greatly reduces on-the-spot installation difficulty, has improved installation effectiveness, has reduced mounting cost.Simultaneously, make the diameter of ball reduce greatly, thereby make that ball node and the rod member comparison harmony that becomes is attractive in appearance, improved in the welded spherical node system bulb diameter greatly than big a lot of these the architectural shortcomings of caliber owing to increased conehead.
As preferably, described hollow ball is a bowl formula hollow ball, is respectively equipped with connecting hole in four quadrants on the end face of hollow ball, is fixed with the connection rod member on the connecting hole.
As preferably, the opening part of described hollow ball is provided with shrouding, and it is corresponding that shrouding and opening part are complementary, and shrouding fixes by stay bolt and hollow ball.
As preferably, an end of described conehead is provided with screens, and OK a karaoke club and rod member are complementary fixing, and described pad is the arc pad, and an end of pad is provided with the imploded arcs morpheme, and the imploded arcs morpheme is complementary with the end face of hollow ball and is connected.
As preferably, described bolt is a high-strength bolt, and bolt connects conehead and pad.
As preferably, described shrouding is circular.
Therefore, a kind of bowl type bolt hollow ball node that the utility model provides, simple and reasonable, easy construction likes to press bearing capacity strong.
