Description
Technical field
The utility model relates to testing equipment field, specially a kind of test for conduit cantilever beam anti-bending strength is filled
It sets.
Background technique
The escape route cantilever beam of the pre-buried C-shaped channel of duct pieces of shield tunnel requires to carry out experiment on flexural behavior, is carrying out this
When experiment on flexural behavior, counterweight Loading Method, Standard test method step are mostly used at present are as follows: section of jurisdiction is holded up as shown in Figure 1:,
Cantilever beam 12 is installed on conduit unit 1, Hanging Basket 21 is hung on cantilever beam 12, cast iron counterweight is placed in classification on Hanging Basket 21
22, cast iron counterweight 22 applies the pulling force of P to cantilever beam 12, and the displacement of 21 end of Hanging Basket is measured under every grade of load action.If it is desired to
It is loaded onto destruction, then load is lasting carries out, until Hanging Basket 21 is collapsed by the drawing of cast iron counterweight 22, cast iron counterweight 22 is scattered on the ground.?
The loading capacity of cast iron counterweight 22 is up to nearly 10kN when Hanging Basket 21 collapses under pressure.The above test process is very time-consuming, it is laborious, must multiple works
People carries.The cost thus tested is also very high, and test process is very dangerous, the cast iron counterweight 22 when being loaded onto destruction
It drops from Hanging Basket 21 to ground, very big threat is constituted to the safety of personnel.
Utility model content
In order to overcome the drawbacks of the prior art, the test equipment that a kind of structure is simple, esy to use, safe and reliable is provided,
The utility model discloses a kind of test devices for conduit cantilever beam anti-bending strength.
The utility model reaches goal of the invention by following technical solution:
A kind of test device for conduit cantilever beam anti-bending strength, the conduit unit including arc, it is characterized in that: also wrapping
Reaction of bearing frame, cantilever beam, load distribution beam and jack are included,
Reaction of bearing frame and cantilever beam both of which are fixed on the cancave cambered surface of conduit unit by foundation bolt, and support is anti-
Both power frame and cantilever beam mutually face and parallel to each other, and load distribution beam is fixed on a cantilever beam, and the two of load distribution beam
End is flushed with the both ends of cantilever beam respectively；
Jack is set between reaction of bearing frame and cantilever beam the two, and the pedestal of jack is fixed on reaction of bearing frame
On, the jacking end of jack resists load distribution beam.
The test device for conduit cantilever beam anti-bending strength, it is characterized in that: reaction of bearing frame and conduit unit
Between be connected and fixed by hound.
When the utility model is used, using counter-force support frame, load is applied to cantilever with jack and load distribution beam
The fixing end of beam and free end, consistent with counterweight loading method, starting jack pushes away cantilever beam application by load distribution beam
The test of power, i.e. analog cantilever beam anti-bending strength.When being tested with the utility model, load can be controlled arbitrarily, load(ing) point can
Choose at random, device is light, it is easy for installation, be further applied load to destroy when without danger.
The beneficial effects of the utility model are: structure is simple, it is easy to use, securely and reliably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram using counterweight Loading Method；
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of test device for conduit cantilever beam anti-bending strength, conduit unit 1, reaction of bearing frame including arc

Reaction of bearing frame 11 and 12 both of which of cantilever beam are fixed on the cancave cambered surface of conduit unit 1 by foundation bolt,
Both reaction of bearing frame 11 and cantilever beam 12 mutually face and parallel to each other, and load distribution beam 13 is fixed on cantilever beam 12,
Both ends of the both ends of load distribution beam 13 respectively with cantilever beam 12 flush；
Jack 2 is set between 12 the two of reaction of bearing frame 11 and cantilever beam, and it is anti-that the pedestal of jack 2 is fixed on support
On power frame 11, the jacking end of jack 2 resists load distribution beam 13；
It is connected and fixed between reaction of bearing frame 11 and conduit unit 1 by hound 14.
Load is applied to outstanding by the present embodiment in use, using counter-force support frame 11, with jack 2 and load distribution beam 13
The fixing end of arm beam 12 and free end, consistent with counterweight loading method, starting jack 2 is by load distribution beam 13 to cantilever beam
12 apply thrust, i.e. 12 anti-bending strength of analog cantilever beam is tested.
