Preferably, projection is provided with the outside of the connection inner core two ends, on the inside of the upper and lower section box section steel tube component
It is provided with the groove with male cooperation.
Preferably, it is described raised for hemispherical projections.
Preferably, the connection inner core is cast steel member, its internal setting band rib structure.
Preferably, the connection inner core two ends arrange chamfering.
Preferably, it is described it is upper and lower section box section steel tube component connection length of inner core in the range of each indentation in two ends it is certain
The grooved angle parts of distance.
Preferably, the bolt is the special bolt for lengthening, and length permission bolt is from one end of box section steel tube component
Through the other end, nut and nut are in the outside of box section steel tube component.
Compared with prior art, the utility model has the advantages that：
1. all operations are carried out on the outside of box section steel tube component, and attended operation is easy, can greatly speed up unit
Room unit spliced speed, connection is reliable, stability is high.
2. inner core can be that cast steel member, or welding production are formed, outer side band kick, convenient fixed when making assembly
Position.Box section steel tube component is connecting the grooved angle parts of each indentation certain distance in two ends in the range of length of inner core, it can be ensured that even
The strength and stiffness for connecing.Connection inner core inner rib can improve the local pressure of connecting node, it is ensured that connection power transmission reliability, carry
High connection bearing capacity.Two chamfer of inner core can make inner core smoothly insert box section steel tube component, improve installation effectiveness.

Specific embodiment
For making the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to specific embodiment
And referring to the drawings, this utility model is further described.It should be understood that these descriptions are simply exemplary, and do not really want
Limit scope of the present utility model.Additionally, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
Embodiment：
As shown in Figure 1,3, a kind of attachment means of box section steel tube component, including upper section box section steel tube component
10th, lower box tee section steel tube component 20, upper section box section steel tube component 10 and lower box tee section steel tube component 20 it is interior
Connection inner core 30 is placed in portion, is connected by connecting inner core 30, and the width for connecting inner core 30 is slightly less than box section steel tube component
Internal diameter.Upper section box section steel tube component 10 and lower box tee section steel tube component 20 pass through bolt respectively and are connected inner core 30 admittedly
It is fixed.Connection 30 upper and lower ends of inner core are respectively arranged with the screw 33 for running through, upper section box section steel tube component 10 and lower box shape
Section steel pipe component 20 is same to be provided with screw corresponding with the screwhole position of connection inner core 30, can pass through stay bolt reality
Now fix.Stay bolt is fixed on box section steel pipe structure from one end of box section steel tube component through the other end by nut
The outside of part.Bolt can be high-strength bolt, or plain bolt.
As shown in Figure 2,4, connect and on the outside of 30 two ends of inner core, be provided with raised 31, in upper and lower section box section steel tube component
Side is provided with and raised 31 grooves for coordinating, and groove can be arranged in the two of upper and lower section box section steel tube component port
On the wall of side.It is raised to be preferably hemispherical projections, can quickly be positioned in assembly.
30 two ends of connection inner core arrange chamfering, connection inner core can be made smoothly to insert box section steel tube component, improved and installed
