Below by embodiment, this utility model is described in further details.
This utility model provides a kind of composite torsion-box testpieces changeover portion, tries for composite torsion-box
Testing part, increase changeover portion at testpieces two ends, changeover portion is also rectangular box section, changeover portion wallboard and testpieces
Wallboard by costal margin bar and docking band plate be attached, wherein Composite Material Stiffened Panel stringer end insert
Enter costal margin bar, changeover portion be attached by side plate with the web of testpieces, the changeover portion other end passes through
Angle box is attached with fixture.
Concrete, as described in Figure 1, this utility model composite torsion-box testpieces changeover portion mainly included
Cross box section 1 and be separately positioned on testpieces connection end 2 and the fixture connection end 3 at transition box section 1 two ends,
Wherein, transition box section 1 is rectangular box assembling structure, and it includes rib 11, wallboard 12 and web 13, two
Block wallboard 12 symmetric design, two pieces of web 13 symmetric designs, wallboard 12 is sequentially connected with web 13
Constituting the transition box section 1 of box-like structure, it is internal that described rib 11 is arranged on described transition box section 1, for right
Transition box section carries out tieing up shape.
It is understood that the master that transition box section 1 is the present embodiment composite torsion-box testpieces changeover portion
Body, its basic configuration is consistent with described composite torsion-box testpieces, is essentially described composite wood magazine
The extension of section testpieces, four limits surrounding described transition box section 1 are respectively wallboard 12 and web 13,
Wallboard 12 as the upper bottom of transition box section 1, by docking band plate (include interior outside jointing strip plate,
Afterwards describe in detail) connect composite torsion-box testpieces upper and lower plates, in like manner, web 13 is as mistake
Cross the left and right side of box section 1, connect composite torsion-box by opposed side panel (23, describe in detail afterwards)
The left and right plate of testpieces, rib 11 is as dimension shape structure, and it is generally located on the two ends of transition box section 1, standby
Selecting in embodiment, it can also be filled in the inside of whole transition box section 1, in the present embodiment, such as Fig. 1
Shown in, rib 11 includes orthogonal some costal margin bars, constitutes similar cellular or box-packed structure.
With reference to Fig. 2, described testpieces linkage section 2 includes outside docking band plate 21, inner side docking band plate 22
And opposed side panel 23, it is to be understood that testpieces linkage section 2 is provided in described composite wood magazine
Between section testpieces and transition box section 1, for connecting both structures, therefore, its structure and transition box section
1 is similar to, and also includes four the plate faces surrounding square structure, the most upper and lower two docking band plates, and a left side
Right two opposed side panels, wherein, arbitrary docking band plate is to be made up of two plates being parallel to each other, and is respectively
Outside docking band plate 21 docks band plate 22 with inner side, and opposed side panel 23 is then only a plate face.
Concrete, refer again to Fig. 2, outside docking band plate 21 arranged in parallel and inner side jointing strip
One end of plate 22 clamps described wallboard 12, and extends formation to the direction of described composite torsion-box testpieces
With the other end of overlap joint groove, docking band plate 22 in described inner side is arranged at intervals with and is opened to described composite
The notch 221 in box section testpieces direction, web 13 can directly be fixed in one end of described opposed side panel 23
On, in an alternate embodiment, the structure of opposed side panel 23 can also be carried out as docking band plate
Design, by achieving a butt joint by the way of the buttcover plate clamped beam web 13 in outside in two.
In the present embodiment, described outside docking band plate 21 docks band plate 22 with described inner side and is bolted
In the both sides, plate face of the wallboard 12 of described transition box section, in other alternate embodiment, it is also possible to pass through
Clamping, glued joint or the fixed form such as welding is attached.
In the present embodiment, with reference to Fig. 1, described fixture connects end 3 and includes four angle boxes, four described angle boxes
One end be separately positioned on four plate faces of transition box section end, concrete, four angle boxes are separately positioned on
On two wallboards 12 and two webs 13, it is right that the other end of angle box is arranged to dock with fixture
Fishplate bar, described buttcover plate removably connects with described fixture.
It is understood that the structure of described angle box can be varied, such as triangular structure and tetragon
Structure, what above-mentioned triangular structure was concrete includes two orthogonal plate faces, and it is steady to strengthen it by hypotenuse
Qualitative, a plate face in two orthogonal plate faces is solid by the connected mode of bolt or welding or splicing
It is scheduled on wallboard 12 or web 13, another plate face is provided with some screws, is bolted
Mode is connected on fixture, or is connected to test in loaded member, such as pressurized strut.
Transition box section 1 is at the structure connecting end 2 away from testpieces, and its wallboard 12 is permissible with web 13
It is Integral design, it is also possible to be to be linked together, if both are integrated by modes such as welding or bolt connections
Design, as shown in Figure 1 or 2, then when transition box section is in time connecting extension at end 2 near testpieces, wall
Plate 12 and web 13 form bifurcated, concrete, and now, described web 13 is in the position near wallboard
The place of putting is provided with flange, and the flange number of degrees are 90 degree, i.e. vertical with wallboard 12 by original web 13
Relationship evolvement is the parallel relation of described flange and described wallboard 12, thus, described flange and described wallboard
Will form gap between 12, described inner side docking band plate 22 i.e. may be provided in described gap.So,
Dock band plate 21 not only by inner side docking band plate 22 with outside and clamp described wallboard 12, further through wallboard
12 clamp described inner side with the flange of web 13 docks band plate 22, defines firm connected mode.
What Fig. 3 gave composite torsion-box testpieces changeover portion specifically applies signal.As it is shown on figure 3, it is multiple
Condensation material box section testpieces is arranged between two composite torsion-box testpieces changeover portions, and by above-mentioned two
Individual composite torsion-box testpieces changeover portion joint test fixture respectively and constraint fixture, thus it is multiple to complete wing
The strength test of condensation material testpieces.
Composite torsion-box testpieces changeover portion of the present utility model is at it with composite torsion-box testpieces even
The one end connect is docked by two notches, and wherein, outside docking band plate docks what band plate was formed with inner side
Overlap joint groove is used for receiving and the base plate of fixing composite material box section testpieces, if arrange on inner side docking band plate
Dry notch is used for receiving the stringer end on described base plate, and additionally opposed side panel is used for docking and fixing compound
The side plate of material cartridge section testpieces, by above-mentioned connected mode, can test composite torsion-box securely
Part is fixed on changeover portion, can eliminate again the load over centre amount at testpieces wallboard two ends to greatest extent, as far as possible
Avoid Composite Panels at two ends owing to be there is accidental destruction by face external force.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than
It is limited.Although this utility model being described in detail with reference to previous embodiment, this area general
Lead to and skilled artisans appreciate that the technical scheme described in foregoing embodiments still can be repaiied by it
Change, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make phase
The essence answering technical scheme departs from the spirit and scope of this utility model each embodiment technical scheme.
