Description
Technical field
This utility model relates to the large-span space structure that a kind of stress is complicated, in particular, relates to the single-layer latticed shell of a kind of high-strength bolt hollow hub node.
Background technology
Existing " spatial mesh structure technical regulation " (JGJ7-2010) specifies, single-layer lattice shell should adopt rigid joint, such as welded spherical node, rod member many employings round steel pipe, rectangular steel pipe and H profile steel etc., it is applied to the node of single-layer lattice shell at present and has welded hollow spherical joints, dividing plate welding node, thick walled steel tube node, tubular joint and a cast steel node etc., but these joint forms all Shortcomings.The welding connection nodes such as welded hollow spherical joints, dividing plate welding node and thick walled steel tube node need on-site consolidation to weld, and construct loaded down with trivial details, are unfavorable for the development of building industrialization, and too much weld seam can affect joints performance；The size of supervisor and arm be there are certain requirements by tubular joint, constrains its application to a certain extent；But cast steel node function admirable high cost, is unsuitable for popularization and application on a large scale.Therefore, a kind of convenient and quick construction, the single-layer lattice shell joint form that stress performance is excellent need to be developed.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of high-strength bolt hollow hub node suitable in single-layer latticed shell is provided, this node is capable of the fabricated construction of single-layer lattice shell, eliminate Site Welding, reduce welding heat affected, improve construction precision, save the duration, and can effectively prevent " vacation is tightened " phenomenon of bolt, it is ensured that connection stiffness and bearing capacity are beneficial to the popularization and application of large span spatial structure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high-strength bolt hollow hub node, including hollow hub, described hollow hub is provided with the connecting hole for connecting high-strength bolt, the outside of described hollow hub is sequentially connected with or without stricture of vagina nut and connecting plate by described high-strength bolt, the inner side of described hollow hub is provided with the pad for fixing described high-strength bolt and nut, being provided with trip bolt on described nut without stricture of vagina, described high-strength bolt is provided with the chute for blocking described trip bolt, described connecting plate is fixedly connected with rod member.
It is provided with ribbed stiffener in described hollow hub.Described ribbed stiffener can be arranged circumferentially the inside at hollow hub.Described ribbed stiffener also can be radially arranged in the inside of hollow hub.
Described pad is annular gasket or arc pad.
Described connecting plate is provided with the weld groove for connecting rod.
Strength grade >=the 8.8S of described high-strength bolt.
Compared with prior art, the technical solution of the utility model is had the benefit that
(1) outside of this utility model hollow core hub is sequentially connected with or without stricture of vagina nut and connecting plate by high-strength bolt, the inner side of hollow hub is provided with the pad for fixing described high-strength bolt and nut, the Path of Force Transfer of node is clear and definite: when node is by axial pressure effect, axle power is transferred to hollow hub by without stricture of vagina nut pressurized；When node is by axle pulling force effect, axle power is transferred to nut by high-strength bolt tension, then is transferred to hollow hub by nut and pad；When direction Moment outside node is subject to net shell plane, moment of flexure is transmitted without stricture of vagina nut pressurized by tensile region high-strength bolt tension and compressive region；When node is subject to direction Moment in net shell plane, moment of flexure is by the extruding force transmission between the nut without stricture of vagina of high-strength bolt tension and pressurized side and hollow hub；The bearing capacity characteristics of the node bearing capacity by high-strength bolt, without stricture of vagina nut and hollow hub together decides on.
(2) this utility model node is due to compact overall structure, rationally distributed, and higher in the out-of-plane bending rigidity of net shell, performance is better than traditional bolt connection node.And can in the factory prefabricated complete after, realize quick-assembling at engineering site and repeat dismounting, and can immediately detect construction quality, effectively prevent " vacation is tightened " phenomenon.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figures 1 to 7, a kind of high-strength bolt hollow hub node, including hollow hub 1, hollow hub 1 is provided with the connecting hole for connecting high-strength bolt 2, the outside of hollow hub 1 is sequentially connected with or without stricture of vagina nut 4 and connecting plate 3 by described high-strength bolt 2, the inner side of described hollow hub 1 is provided with the pad 7 for fixing described high-strength bolt 2 and nut 8, and pad 7 is annular gasket or arc pad, adopts and also should carry out the flat process of milling at the inwall correspondence position of hollow hub 1 during annular gasket；Nut without stricture of vagina 4 is provided with trip bolt 5, high-strength bolt 2 is provided with the chute 6 for blocking trip bolt 5, chute 6 is made up of deep trouth and shallow slot, connecting plate 3 is provided with weld groove, connecting plate 3 is welded and fixed by weld groove and rod member 9, in the present embodiment, rod member 9 is concrete filled rectangular steel tube members, and the end of rod member 9 carries out bevel cut process.
