Embodiment
The utility model is more fully illustrated below with embodiment.The utility model can be presented as it is a variety of not
Same form, it is not construed as being confined to the exemplary embodiment described here.
For ease of explanation, space relative terms such as " on ", " under " " left side " " right sides " can be used herein, for saying
The element or feature shown in bright figure is relative to another element or the relation of feature.It should be understood that except in figure
Outside the orientation shown, spatial terminology is intended to include the different azimuth of device in use or operation.If for example, in figure
Device is squeezed, be stated as positioned at other elements or feature " under " element will be located into other elements or feature " on ".Cause
This, exemplary term " under " both upper and lower orientation can be included.Device can be positioned otherwise（It is rotated by 90 ° or is located at
Other orientation）, can correspondingly be explained used herein of the relative explanation in space.
As shown in Figure 1 and Figure 2, the bracing means of the bolt-ball net frame pull bar in the present embodiment and node, including two reinforcings
Outer tube 6 and some set Screw arbor with nut at both-ends 3, fastening nut 4；Reinforce the both sides original rack drawing that outer tube 6 is arranged on bolted spherical node 7
On bar 5, it is fixedly connected by the Screw arbor with nut at both-ends 3 of supporting setting with fastening nut 4.Reinforce outer tube 6 and the composition of annular plate 1 adds
Firmware；The reinforcing member of the both sides of bolted spherical node 7 is linked together by Screw arbor with nut at both-ends 3 and fastening nut 4, to bolt-ball net frame
Pull bar and node are reinforced.The former rack pull bar 5 that the both sides of bolted spherical node 7 reinforce should be point-blank.
Reinforcing member can also use other forms.For example, as shown in figure 3, choose point-blank in bolt ball-joint
The both sides original rack pull bar 5 of point 7, it is circumferential uniformly by four steel plates 8 outside two former tube walls of rack pull bar 5 respectively, along former rack
The central axis direction extension of pull bar 5 is welded；Then floor is welded to connect close to one end of bolted spherical node 7 in steel plate 8,
Connect and screw rod mounting hole 1-1 is set on floor；The reinforcing member of the both sides of bolted spherical node 7 is connected to by screw rod mounting hole 1-1

Floor ribbed stiffener 2 is provided between annular plate 1 and former rack pull bar 5；Further improve the strong of annular plate 1
Degree.
During reinforcing, installation steps are as follows：
1）Annular plate 1 is respectively welded on the former rack pull bar 5 of the both sides of bolted spherical node 7 using bilateral angle welding,
The screw rod mounting hole 1-1 of annular plate 1 must be aligned；
2）Six floor ribbed stiffeners 2 are used into bilateral fillet weld seam with annular plate 1, former rack pull bar 5 respectively；
3）The front end for reinforcing outer tube 6 is alignd with the side of annular plate 1, outer tube 6 is reinforced and uses slope with annular plate 1
Mouth penetration weld connection；
4）Outer tube 6 is reinforced to be connected with former rack pull bar 5 using interruption angle welding；
5）Screw arbor with nut at both-ends 3 is passed through into corresponding screw rod mounting hole 1-1 on the annular plate 1 on both sides；Adjusted by fastening nut 4
Whole pulling force, the pulling force on bolted spherical node 7 is transferred on Screw arbor with nut at both-ends 3；Complete to reinforce.
2 times of the thickness of annular plate 1 not less than the wall thickness of the steel pipe of former rack pull bar 5.
The thickness of floor ribbed stiffener 2 is the 90% to 110% of the wall thickness of the steel pipe of former rack pull bar 5；Reduce after welding to original
The influence of the steel strength of rack pull bar 5.
The technical solution of the utility model is by floor and split bolt construction measure, on the premise of bolt sphere no-welding
The reinforcing of bolt sphere Elements of Space Grid Truss pull bar and node is realized, there is simple structure, the advantage such as convenient of constructing.
Above-mentioned example is only intended to illustrate the utility model, in addition, also a variety of different embodiments, and these
Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore, no longer arrange one by one herein
Lift.
