Description
Technical field
The utility model belongs to technical field of structural engineering, more particularly to a kind of connection knot for closing pre-embedded bolt in rod member
Structure.
Background technology
Latticed shell structure has the loading characteristic of member structure and shell structure concurrently, have span ability is big, architectural image is abundant,
The distinguishing features such as economic indicator is superior.Latticed shell structure is at home and abroad developed rapidly in decades, is still actual work so far
One of space structure form being most widely used in journey.Wherein the node of single-layer lattice shell, rod member quantity are few, and architectural effect is slim and graceful
Succinctly, permeability is good, particularly suitable for free form surface, complex object and the high building of aesthetic.
According to section form, single-layer lattice shell rod member mainly includes round steel pipe, rectangular steel pipe and i-steel component.Single-layer lattice shell
In, rod member is also subject to Moment in addition to axle power, and shell surface face Moments are typically much deeper than moment of flexure in face, therefore is closed from stress
Angle is managed, has the big rectangular steel pipe of section power axle, major axes orientation bending rigidity than round steel pipe more suitable for single-layer lattice shell.This
Outside, rectangular steel pipe can directly support roofing, it is not necessary to additional purlin system, it is ensured that architectural effect is succinctly penetrating.With
I-steel component is compared, and rectangular steel pipe has more preferable weak axle bending rigidity and torsional rigidity, and good appearance, be easy to keep a public place clean,
Anti-corrosion.
Although square-section rod member single-layer lattice shell excellent performance, node or interconnection technique development relatively lag behind, and cause
Practical Project interior joint using welding, seriously constrains its Popularization And Development mostly.Existing rectangular steel pipe single-layer lattice shell is assembled even
In connection technology, for convenience of construction and installation, rectangle boom end partial cross-section is often sacrificed.Such as Mero BK nodes and the SEELE section of Germany
Put in the perforate of the rod member edge of a wing, realize assembling, weaken the bearing capacity and seal of rod member to a certain extent.And existing dress
With formula node because complex process, the accuracy of manufacture require that the reasons such as height cause cost higher, it is not easy to promote.
Utility model content
The purpose of this utility model is the deficiency for existing joint system, there is provided a kind of to close pre-embedded bolt in rod member
Attachment structure.The utility model ensure that the integrality in rectangular steel pipe section by pre-embedded bolt.Simultaneously but also with connection component
Less, the advantages of processing technology is simple, and manufacturing cost is low.
The purpose of this utility model is achieved through the following technical solutions：The company of pre-embedded bolt in a kind of closing rod member
Binding structure, it includes node body, node end plate, rod member end plate, rod member, bolt；The node side plate weld is at the end of node body
Portion, the rod member end plate are welded on the end of rod member, and screwed hole is provided with the node end plate, is provided with the rod member end plate logical
Hole, the bolt are spun through through hole with screwed hole, and two or three nuts are connected with the bolt.
Further, the quantity of the bolt is two or three.
The beneficial effects of the utility model are the bearing capacitys by rod member end pre-embedded bolt, not weakening rod member itself,
So that the attachment structure has higher bending rigidity and bearing capacity；Compared to other node types of attachment, the utility model passes through
The tightening way of double nut or three nuts, the assembly at node connection scene is realized, mounting means is simple, assembled efficiency high；This
Utility model is simple in construction, and Path of Force Transfer is clear, and control parameter is few, is easy to structure design；This attachment structure building block is
Common component, low manufacture cost, prefabricated degree is high, is advantageous to application.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of attachment structure for closing pre-embedded bolt in rod member, it includes node body 1, node end plate 2, bar
Part end plate 7, rod member 8, bolt 6；The node end plate 2 is welded on the end of node body 1, and the rod member end plate 7 is welded on rod member 8
End, be provided with screwed hole on the node end plate 2, be provided with through hole on the rod member end plate 7, the bolt 6 through through hole with
Screwed hole is spun, and two or three nuts are connected with the bolt 6.
Preferably, the quantity of the bolt 6 is two or three.
The tightening method of the node connecting structure of pre-embedded bolt in rod member is closed, this method comprises the following steps that：
1）, in factory prefabricated node body 1 and node end plate 2, and open two or three screw threads in advance on node end plate 2
Hole, then node body 1 and node end plate 2 are welded together；
2）, in factory prefabricated rod member 8 and rod member end plate 7, and open two or three through holes in advance on rod member end plate 7；
3）, bolt 6 is previously threaded through the through hole on rod member end plate 7, then rod member end plate 7 and rod member 8 are welded together,
To prevent bolt falling in operation, then two or three nuts are screwed in into the middle part of bolt 6 in advance, such as schematic diagram 2-a after completing
Shown in Fig. 2-b.
4）, assembled in situ when see schematic diagram 2-a and Fig. 2-b, if two nuts, by inner nut 5 apply positive-torque,
Bolt 6 is screwed in into node end plate 2, negative torque is applied by outer nut 3, bolt 6 is screwed out into node end plate 2；If three spiral shells
Mother, positive-torque or negative torque are directly applied by middle nut 4, by the precession of bolt 6 or screw out gusset plate 2；To ensure to install, up and down
The precession of two screw rods should keep synchronous.
5）, when precession to outer nut 3 and node end plate 2 are held out against, that is, complete assembling.During practical set, when bolt 6 screws in
During to certain depth, it is also contemplated that assembling is completed.Assembling complete when according to the diverse location of nut see Fig. 3-a, Fig. 3-b, Fig. 3-
C, Fig. 4-a and Fig. 4-b.Schematic diagram when connected mode is completed when Fig. 5 is three bolts of the utility model assembling type node.
The node connecting structure of pre-embedded bolt is applied to rectangular steel pipe monolayer net in closing rod member provided by the utility model
In shell structure assembly, on the basis of ensureing not weaken rod member, prefabricated degree is high, and assembly method is simple, and stress performance is good, have compared with
High application potentiality.
