Clothes act device 6, and such experimental rig simple structure, power transmission are clear and definite, easy to use.Shortcoming be it is immovable, can only be fixed
Place uses.And self-balancing type light steel wall shear test device is then mobile product, can be tested in different places.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is removable, without with
Basis connection, load is not transmitted to self-balancing type light wall shear test device basic, easy to use.
The purpose of the present invention can be achieved through the following technical solutions：A kind of self-balancing type light wall shear test dress
Put, it is characterised in that including front door frame, rear door frame, described front door frame is connected with rear door frame by lateral support, after described
Door frame is provided with back timber and nose girder, and experiment wall is placed between back timber and nose girder, described back timber side connection level jack,
Applying horizontal pressure force, back timber upper end connects vertical jack, applies vertical pressure, and described front door frame is provided with skewed horizontal load,
Horizontal internal force caused by skewed horizontal load transmission level jack, is provided with vertical pull bar between front door frame and rear door frame middle part, transmits
Internal force caused by vertical jack.
Described back timber one end is fixed on rear door frame, other end connection level jack.
Described nose girder is located on rear door frame bottom plate, and guide rail is provided with nose girder, and experiment wall can move on nose girder.
Described level jack can provide 30 tons of Tensile or Compressive Loading, and vertical jack can provide 50 tons of pressure loadings.
Compared with prior art, it is of the invention, self-balancing type light steel wall shear test device have it is removable, without and base
Plinth connection, load is not transmitted to the advantages of basic, easy to use, be a kind of industrialized product.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As described in Figure 2, a kind of self-balancing type light wall shear test device, including front door frame 1, rear door frame, it is described
Front door frame is connected with rear door frame by lateral support, and described rear door frame is provided with back timber 2 and nose girder 3, and experiment wall 4 is placed in top
Between beam 2 and nose girder 3, described one end of back timber 2 is fixed on rear door frame, and other end connection level jack 5 applies horizontal pressure
Power, the upper end of back timber 2 connect vertical jack 6, apply vertical pressure, and described front door frame 1 is provided with skewed horizontal load 7, oblique branch
Horizontal internal force caused by the transmission level jack 5 of support 7, vertical pull bar 8 is provided between front door frame and rear door frame middle part, is transmitted vertical
Internal force caused by jack.
Described nose girder is located on rear door frame bottom plate, and guide rail is provided with nose girder, and experiment wall can move on nose girder.
During experiment, front door frame 1, rear gate architecture are into self equilibrium systemses, without being connected transmission experiment counter-force with basis, it is only necessary to
Appropriate antidumping connection.As seen from the figure, rear door frame is while connection level jack 5 applies lateral Cyclic Loading, rear door frame upper end
Connect vertical jack 6 and apply vertical pressure.The oblique strut 7 of front door frame 1 is mainly transmitted caused by level jack 5 in level
Power, the vertical pull bar 8 at middle part mainly transmit internal force caused by vertical jack 6.The tension and compression that level jack 5 can provide 30 tons carry
Lotus, vertical jack 6 can provide 50 tons of pressure loadings.
The device can carry out experiment on Shearing Resistance, compression-shear test, the pressurized tests of light steel wall.The height dimension model of wall
It is 600mm~5000mm to enclose for 2700mm~3300mm, width dimensions scope.The device can also carry out holding for other light steel walls
Carry power experiment.
