Description
Technical field
The utility model belongs to Aeronautical Test Technology field, more particularly to a kind of trough girder test fixture.
Background technology
The experiment of groove profile spar is tested using box section testpieces mostly, and experimental scale is larger, and testpieces clamping fixture is set
Meter is complicated, and design, production cost are high, cycle length；Single groove profile beam test, its jig Design is disposable design, for
The spar of different height needs to design different test fixtures, can not reuse, and causes the wasting of resources, experimentation cost height.
Utility model content
The purpose of this utility model is to provide a kind of trough girder test fixture design, changes and solves current groove profile beam test
Part fixture is without versatility, not re-usable problem.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of trough girder test fixture, for clamping
Trough girder testpieces, it includes
One web angle box, web angle box have two loading ends being arranged in a mutually vertical manner, and a loading end is consolidated with testpieces
It is fixed；
Two edge strip exterior angle boxes and two edge strip interior angle boxes, edge strip exterior angle box and edge strip interior angle box are respectively provided with orthogonal
Two mounting surfaces, edge strip exterior angle box are installed on by a mounting surface on the outside of the edge strip of testpieces, and the edge strip interior angle box passes through
One mounting surface is installed on the inside of the edge strip of testpieces.
Further, the loading end that web angle box (2) is connected with testpieces (1) is provided with multiple fixations uniformly arranged
Hole, according to the arrangement of fixing hole and quantity described in the size adjusting of testpieces (1), to ensure web angle box (2) and testpieces (1)
Fixation.
Further, the width of edge strip exterior angle box (3) is consistent with the edge strip outside width of testpieces (1), and in edge strip
The width of angle box (4) is consistent with the edge strip inboard width of testpieces (1).
Further, web angle box (2) uninstalled loading end and edge strip exterior angle box (3) and edge strip interior angle box (4)
Uninstalled mounting surface is coplanar.
Trough girder test fixture of the present utility model is individually designed in the blessing of web and edge strip, easy for installation；It is applicable
In the trough girder of different edge strip height, and may be reused.
Brief description of the drawings
Accompanying drawing herein is merged in specification and forms the part of this specification, show meet it is of the present utility model
Embodiment, and for explaining principle of the present utility model together with specification.
Fig. 1 is the front elevation after the test fixture installation of the embodiment of the utility model one.
Fig. 2 is the reverse side figure after the test fixture installation of the embodiment of the utility model one.
Reference：
1- testpieces, 2- webs angle box, 3- edge strips exterior angle box, 4- edge strip interior angle boxes.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.
It is as depicted in figs. 1 and 2 the schematic diagram after trough girder testpieces fixture of the present utility model installation, it is new in this practicality
In type, trough girder testpieces 1 generally by a monoblock web and is arranged on web edge and vertically disposed with force bearing plate
Edge strip is formed, and reinforcement is provided between edge strip.
And trough girder test fixture of the present utility model is used to clamp groove profile beam test part, it includes：
One web angle box 2, referring to Fig. 1, web angle box 2 has two loading ends being arranged in a mutually vertical manner, in two carryings
The rib provided with multiple triangles is connected to two loading ends between face so that 2 substantially triangular structure of web angle box, abdomen
One loading end of plate angle box 2 is fixed with testpieces 1, and another loading end is concordant with the edge substrate of testpieces 1；Two edge strip exterior angle boxes 3
And two edge strip interior angle boxes 4, edge strip exterior angle box 3 and edge strip interior angle box 4 are similar with the generally structure of web angle box 2, and it is respectively provided with phase
Mutually two vertical mounting surfaces, edge strip exterior angle box 3 are installed on by a mounting surface on the outside of the edge strip of testpieces 1, and edge strip interior angle box 4 is logical
A mounting surface is crossed to be installed on the inside of the edge strip of testpieces 1.For edge strip of the testpieces 1 per side, edge strip exterior angle box 3 and edge strip
Interior angle box 4 has been clamped in the both sides of edge strip, and so edge strip can be fixed.
In the fixation of above-mentioned parts or installation process, all parts are consolidated using the connected mode of bolt
It is fixed, you can to ensure that connection has preferable intensity, can be removed and installed repeatedly again.
Therefore the loading end that web angle box 2 is connected with testpieces 1 is provided with multiple fixing holes uniformly arranged, but in reality
During use, arrangement and the quantity of the fixing hole should be adjusted according to the size of testpieces 1, to ensure web angle box 2
With the fixation of testpieces 1.
In the utility model, edge strip exterior angle box 3 is designed to only connect with edge strip, and its mounting surface being connected with edge strip
Width is identical with the width on the outside of edge strip；Edge strip interior angle box 4 is also designed to only connect with edge strip, its mounting surface being connected with edge strip
Width it is identical with the width on the outside of edge strip.
Web angle box 2 is designed in the outside of trough girder testpieces 1 (side of smooth no rib), to meet to different height
The clamping of trough girder testpieces 1 needs, on edge strip along edge strip length direction prefabricated multiple rows of link bolt hole, according to actual edge
Bar width installs connecting bolt.
Trough girder test fixture of the present utility model is individually designed in the blessing of web and edge strip, easy for installation；It is applicable
In the trough girder of different edge strip height, and may be reused.
It is described above, optimal embodiment only of the present utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with
The scope of the claims is defined.
