Description
Technical field
The invention belongs to Aeronautical Test Technology field more particularly to a kind of trough girder test fixtures.
Background technique
The test of groove profile spar mostly uses box section testpieces to be tested greatly, and experimental scale is larger, and testpieces clamping fixture is set
Meter is complicated, design, high production cost, and the period is long；Individual groove profile beam test, fixture design is disposable design, for
The spar of different height needs to design different test fixtures, can not reuse, result in waste of resources, and experimentation cost is high.
Summary of the invention
The object of the present invention is to provide a kind of trough girder test fixtures, change and solve current trough girder testpieces fixture not
With versatility, not re-usable problem.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of trough girder test fixture, for clamping groove profile
Beam test part comprising
One web angle box, web angle box have two loading ends being arranged in a mutually vertical manner, and a loading end and testpieces are solid
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 all have orthogonal
Two mounting surfaces, edge strip exterior angle box are installed on the outside of the edge strip of testpieces by a mounting surface, 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 connect with testpieces (1) is equipped with multiple evenly arranged fixations
Hole, according to the arrangement of fixation hole described in the size adjusting of testpieces (1) and quantity, to guarantee 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 edge strip in
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 invention is individually designed in the aid of web and edge strip, easy for installation；Suitable for not
With the trough girder of edge strip height, and may be reused.
Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets implementation of the invention
Example, and be used to explain the principle of the present invention together with specification.
Fig. 1 is the front elevation after the test fixture installation of one embodiment of the invention.
Fig. 2 is the reverse side figure after the test fixture installation of one embodiment of the invention.
Appended drawing reference:
1- testpieces, 2- web angle box, 3- edge strip exterior angle box, 4- edge strip interior angle box.
Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.
It is as depicted in figs. 1 and 2 the schematic diagram after trough girder testpieces fixture installation of the invention, in the present invention, slot
Type beam test part 1 under normal circumstances by a monolith web and setting web edge and with the vertically disposed edge strip group of force bearing plate
At equipped with reinforcing rib between edge strip.
And trough girder test fixture of the invention is for clamping groove profile beam test part comprising:
One web angle box 2, referring to Fig. 1, web angle box 2 has two loading ends being arranged in a mutually vertical manner, and carries at two
Rib between face equipped with multiple triangles is connected to two loading ends, so that the substantially triangular structure of web angle box 2, abdomen
A loading end and testpieces 1 for plate angle box 2 is fixed, and another loading end is concordant with 1 edge substrate of testpieces；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 2 generally structure of web angle box, all have phase
Mutually two vertical mounting surfaces, edge strip exterior angle box 3 are installed on the outside of the edge strip of testpieces 1 by a mounting surface, 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 the edge strip of the every side of testpieces 1, edge strip exterior angle box 3 and edge strip
Interior angle box 4 has been clamped in the two sides of edge strip, edge strip can be fixed in this way.
In the fixation or installation process of above-mentioned parts, the connection type for being all made of bolt is consolidated all parts
It is fixed, that is, it can guarantee that connection has preferable intensity, and installation can be dismantled repeatedly.
Therefore the loading end that web angle box 2 is connect with testpieces 1 is equipped with multiple evenly arranged fixation holes, but in reality
In use process, the arrangement and quantity of the fixation hole should be adjusted according to the size of testpieces 1, to guarantee web angle box 2
With the fixation of testpieces 1.
In the present invention, edge strip exterior angle box 3 is designed to only connect with edge strip, and the width of its mounting surface connecting with edge strip
With it is of same size on the outside of edge strip；Edge strip interior angle box 4 is also designed to only connect with edge strip, the width for the mounting surface connecting with edge strip
Degree with it is of same size on the outside of edge strip.
The design of web angle box 2 is in the outside (side of smooth no rib) of trough girder testpieces 1, 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 practical edge
Width installation connection bolt.
Trough girder test fixture of the invention is individually designed in the aid of web and edge strip, easy for installation；Suitable for not
With the trough girder of edge strip height, and may be reused.
The above, optimal specific embodiment only of the invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
