According to the assembly type hollow hub joint, assembly type construction of a single-layer latticed shell can be implemented, field welding is eliminated, welding heat effect is reduced, construction precision is improved, time limit for a project is shortened, a false screw situation of the bolts can be effectively prevented, and rigidity and bearing force of the joint are ensured to facilitate popularization and application of a large-span space structure.

Description

A kind of assembled hollow hub node
Technical field
The present invention relates to the large-span space structure that a kind of stress is complicated, in particular, relate to the single-layer latticed shell of a kind of assembled 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.
Summary of the invention
The invention aims to overcome deficiency of the prior art, a kind of assembled 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.
It is an object of the invention to be achieved through the following technical solutions:
A kind of assembled hollow hub node, including hollow hub, described hollow hub is provided with the screwed hole for fixing bolt, the outside of described hollow hub is connected to the connecting plate with weld groove by described bolt, bolt between described connecting plate and hollow hub is provided with the nut without stricture of vagina with trip bolt, being provided with on described bolt and the chute for blocking described trip bolt, connecting plate is connected to rod member by described weld groove.
Strength grade >=the 8.8S of described bolt.
Described connecting plate is additionally provided with ribs.
Compared with prior art, technical scheme is had the benefit that
(1) outside of hollow core hub of the present invention is sequentially connected with or without stricture of vagina nut and connecting plate by bolt, and the Path of Force Transfer of hollow hub 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 hollow hub by bolt tension; When direction Moment outside node is subject to net shell plane, moment of flexure is transmitted without the extruding force between stricture of vagina nut and hollow hub by tensile region 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 bolt tension and pressurized side and hollow hub, and when there is external fin, moment of flexure is transmitted by bolt tension and external fin pressurized; 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) bolt of hollow hub node of the present invention selects strength grade at the high-strength bolt of more than 8.8S, compact overall structure, rationally distributed, 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 bolt executes stubborn quality and can immediately detect, effectively prevent " vacation is tightened " phenomenon.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figures 1 to 7, a kind of assembled hollow hub node, including hollow hub 1, hollow hub 1 is provided with the screwed hole for fixing bolt 2, it is positioned on the bolt 2 outside hollow hub 1 and is connected to connecting plate 3, bolt 2 between connecting plate 3 and hollow hub 1 is provided with the nut without stricture of vagina 4 with trip bolt 5, bolt 2 is provided with and the chute 6 for blocking described trip bolt 5, described chute 6 is made up of deep trouth and shallow slot, being provided with weld groove 8 on connecting plate 3, connecting plate 3 is welded and fixed by weld groove 8 and rod member 7.
The present embodiment hollow core hub 1 is chosen the technique such as thick walled steel tube or round steel adopts cutting, milling to put down, boring, tapping and is made, the high-strength bolt of strength grade >=8.8S selected by bolt 2, high-strength bolt need to meet " high-strength bolt used for steel net frame bolt ball node " (GB/T16939-1997) requirement, and reach need to ensure at least can back-out 3 pitch length from screwed hole, and collisionless each other; The degree of depth of screwed hole is no less than 1.3 times of high-strength bolt nominal diameters, the central axis of screwed hole intersects with the central axis of hollow hub 1, the angle of cut is determined by the angle of cut of rod member 7 and hollow hub 1 central axis, two screwed holes connecting same rod member 7 are parallel to each other, milling flat outside hollow hub 1 should be vertical with screwed hole, and width is more than the external diameter without stricture of vagina nut 4; Nut without stricture of vagina 4 material should adopt Q235, Q345 or No. 45 steel, and should correspond with the regulation of GB/T700, GB/T1591 and CB/T699; Connecting plate 3 adopts steel plate cutting, groove milling and boring to make; Rod member 7 adopts rectangular steel pipe, and after rod member 7 adopts docking weld groove 8 with connecting plate 3, complete penetration is connected, it is ensured that wait strong. The model of bolt 2 and the bore position of hollow hub 1 upper screwed hole are determined by joints; When between the central axis of rod member and hollow hub 1 during out of plumb, slope should be put on the milling flat of hollow hub 1, make rod member be perpendicular to the hollow hub milling flat after putting slope. When to node rigidity in net shell plane and requirement for bearing capacity higher time, the external diameter without stricture of vagina nut 4 can be increased or ribs 9 (as shown in Figure 7) is set in connecting plate 3 both sides, the width of ribs 9 is identical with the length without stricture of vagina nut 4, length has enough nuts without stricture of vagina 4 to execute stubborn space when should ensure that construction, hollow hub node construction of the present invention should carry out hollow hub female thread and back-out the inspection of degree after completing, just can carry out other operations such as hollow hub capping after qualified.
First from the connecting plate side with weld groove, bolt being inserted the preformed hole position connecting plate during node installation of the present invention, fix without stricture of vagina nut and trip bolt at connecting plate opposite side temporarily, and connecting plate and rod member are welded to connect, above operation completes in processing factory; At engineering site, bolt is directed at hollow hub bore position, tightens without stricture of vagina nut until bolt is back-outed degree and execute screwing torque and reach requirement inside hollow hub.
