Position Large Shear tests the horizontal bearing diagonal device of Plumb load.
The horizontal bearing diagonal device that Plumb load is tested for Large Shear in situ of the present utility model is relative by being fixed on
Two pieces of tilt props (1) that two for answering are tested pits on wall；Two short steel poles of outside nut line will be carried with two movable pins (10)
(2) connect together the horizontal support of composition with the steel pipe (3) of two with internal thread line；Be placed in horizontal support lower section its structure with
Two bearing diagonals (4) of horizontal support identical, one end of two bearing diagonals (4) is connected to two pieces tiltedly by movable pin (10)
On fagging (1), the other end is connected on the boss of ship shape code (5) two sides by movable pin (10)；One end is by living
Two vertical pulling force steel poles (6) that dynamic pin (10) is connected on ship shape code (5) end face, are placed in two pulling force steel pole (6) tops
And I-steel (9) composition clamped by four nuts (8) and two clamping plates (7).
The utility model is prepared according to a conventional method using the product and material of market sale.
Operation principle of the present utility model is：
The horizontal support being made up of the female steel pipe (3) of two threaded steel poles (2) and two, by two
Movable pin (10) is connected with corresponding two piece tilt prop (1) of testing pits, and with pipe wrench rotating steel tube (3), makes two pieces of tilt props (1)
To be reinforced tightly withstand on and tested pits on wall, to stably.
Then rotate one end and tilt prop (1) is connected in by pin (10), the other end is also to be connected to ship by pin (10)
Two bearing diagonal steel pipes (4) on shape code (5), by the screw thread of screw its stretching hole wall and ship shape code (5) are made, and by adjusting
Two steel pipes (4), and using their bearing diagonal relation, make ship shape code (5) uniform force and keep balance and stability.And pass through two
The I-steel (9) of root pulling force steel pole (6), four nuts (8) and two clamping plates (7) clamping is naturally also with regard to balance and stability.
As needed the size of vertical load, determines the number for installing horizontal bearing diagonal device, makees anti-using I-steel (9)
Power, that is, provide Plumb load.
The beneficial effects of the utility model are：
1st, as a result of ingenious device, the counter-force of test crater wall is transferred on I-steel, is provided to Plumb load
Counter-force, it is to avoid the trouble of weight is found in transport, and equipment is light.
2nd, easy for installation flexible, as needed the size of vertical load, determines the number for installing horizontal bearing diagonal device.
3rd, high working efficiency, experimental data reliability, convenient transportation.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
Below in conjunction with the accompanying drawings the utility model will be further described.
The horizontal bearing diagonal device that Plumb load is tested for Large Shear in situ of the present utility model, its structure is with practical
Described in new content part and shown in accompanying drawing.Prepared according to a conventional method using the product and material of market sale.
Before test, first in the direction that major axis is tested pits perpendicular to rectangle, by certain in the corresponding crater wall in test block top
Inclination angle in "eight" shape install two pieces of tilt props 1；Two short steel poles 2 of outside nut line will be carried with two movable pins 10 again
Connect together composition horizontal support with steel pipe 3 of the two with internal thread line；It is placed in horizontal support its structure of lower section and horizontal support
Two bearing diagonals 4 of identical, one end of two bearing diagonals 4 is connected on two pieces of tilt props 1 by movable pin 10, another
End is also to be connected on the boss of the two sides of ship shape code 5 by movable pin 10；One end is connected to by movable pin 10
Two vertical pulling force steel poles 6 on the end face of ship shape code 5, are placed in two tops of pulling force steel pole 6 and by four nuts 8 and two pieces of folders
Plate 7 clamps I-steel 9.General scene large-sized experiment has four test blocks, need to respectively install set of horizontal type bearing diagonal at the two of I-steel 9
Device.
During test, first with pipe wrench steel pipe 3 of the rotation with internal thread line, by docking with the screw thread of short steel pole 2, to two
The reinforcing of tilt prop 1 hold out against crater wall stratum, stablize two pieces of tilt props 1, then rotated simultaneously with pipe wrench again and carry internal thread line
Two oblique steel pipes 4, be also by docking with the screw thread of short steel pole 2, to two tilt prop 1 reinforcing hold out against, by adjustment two
The oblique steel pipe 4 of root, and using their bearing diagonal relation, make the uniform force of ship shape code 5 and keep balance and stability, and pass through two drawings
6, four nuts 8 of power steel pole and the I-steel 9 of the clamping of two clamping plates 7 are naturally also with regard to balance and stability.
Large Shear test in situ is done, general Plumb load test system, including vertical jack, pressure to be installed
Table, dial gauge of vertical placement of record sedimentation etc.；Level to be also installed to loading test system, horizontal addload crater wall is done instead
Power, dial gauge of level of the level to the jack, pressure gauge and recording level for disposing to displacement to placement.
During test, the vertical load for designing first is applied to first piece of sample, with above-mentioned I-steel 9 counter-force is made, passed through
The pressure of jack is adjusted, makes vertical load be equal to design load, after stablizing, then design level class of loading adjusts level thousand
Jin is pushed up, and makes horizontal loading be equal to the horizontal loading of design, again by design load loading next stage horizontal loading after stablizing, until examination
Sample is destroyed.
To second and third, four pieces of samples make similar test by design load, and note down, diagrammatically or least square
Method obtains cohesive strength C and internalfrictionangleφ.
Jing is actually used to be shown, the utility model is fully achieved design requirement.Not only high working efficiency, experimental data can
Lean on, moreover it is possible to light transport.
