Description
Technical field
The utility model relates to concrete test apparatus field, is specifically related to automatic leveling formula concrete splitting tensile tester.
Background technology
Usually, concrete compressive strength is often paid close attention at building field, on the weak side to concrete tensile strength attention rate, but at road and bridge and require concrete tensile strength in high structural elements, except having requirement to concrete crushing strength grade, especially pay close attention to concrete tensile strength, test concrete tensile strength, the concrete tensile splitting strength of domestic usual employing replaces.
At present, to concrete splitting tensile strength test employing is that pressure testing machine coordinates splitting tensile test fixture to complete, concrete sample is installed in Split-tension of Rolled fixture, pressing machine pressure testing is adopted to carry out the acquisition of test figure, Split-tension of Rolled fixture used at present adopts steel to make, comprise top board, base plate and U-shaped steelframe, top board is wherein identical with base plate size, arc is with concrete surface, top board is positioned in the groove of U-shaped steelframe of connecting bottom board and top board, during test, the top board people of Split-tension of Rolled fixture is lifting by testing crew, concrete sample is positioned in fixture, put down top board and push down concrete sample, by pressure testing machine applied voltage test.
The weak point of adopting in this way is: the base plate of this device is with radian, middle high both sides are low, concrete sample is placed on base plate easily to tilt, be difficult to ensure concrete sample bottom surface level, and it is very thick and heavy that top board adopts cast iron to make, inconvenient testing crew places concrete, be difficult to ensure that concrete sample is in the center of Split-tension of Rolled fixture, needs people to be lifting top board when placing test specimen, excessively expends the muscle power of testing crew.Therefore, adopt current fixture to test both consumption test personnel muscle power, testing efficiency is low, and is difficult to ensure that test specimen is placed in the middle, and test accuracy is difficult to ensure.
Therefore, be necessary to carry out Curve guide impeller to current concrete splitting tension fixture, invent a kind of impact can eliminated radian and concrete sample is placed, and top board can the device of automatic lifting, can either leveling place concrete sample in a device again can automatic lifting the automatic leveling formula concrete splitting tensile tester of leveling top board.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provides a kind of automatic leveling formula concrete splitting tensile tester.
The utility model includes base plate, one group of shank, one group of support spring, one group of leveling bar, one group of leveling spring, top board and one group of bearing rod, base plate and top board are the rectangular slab wearing radian, the cambered surface of base plate upward, one group of shank is arranged on the corner at base plate top, top board is positioned at above base plate, and cambered surface down, one group of bearing rod is arranged on the corner bottom top board, one group of support spring two ends is set on one group of shank and one group of bearing rod, base plate has one group of hole, one group of leveling bar is arranged in the hole of base plate, one group of leveling spring is arranged on base plate through one group of leveling bar.
The radian height of described base plate and top board cambered surface is 20mm, and radius of the radian is 75mm.
Described shank is identical with bearing rod length, and length is less than 1/2 piece lengths.
The radian that length under described leveling spring free state is greater than base plate is high.

Embodiment
As Fig. 1, automatic leveling formula concrete splitting tensile tester shown in Fig. 2 and Fig. 3, it includes base plate 1, one group of shank 2, one group of support spring 3, one group of leveling bar 4, one group of leveling spring 5, top board 6 and one group of bearing rod 7, base plate 1 and top board 6 are the rectangular slab wearing radian, the cambered surface of base plate 1 upward, one group of shank 2 is arranged on the corner at base plate 1 top, top board 6 is positioned at above base plate 1, and cambered surface down, one group of bearing rod 7 is arranged on the corner bottom top board 6, one group of support spring 3 two ends is set on one group of shank 2 and one group of bearing rod, base plate 1 has one group of hole, one group of leveling bar 4 is arranged in the hole of base plate 1, one group of leveling spring 5 is arranged on base plate 1 through one group of leveling bar 4.
The radian height of described base plate 1 and top board 6 cambered surface is 20mm, and radius of the radian is 75mm.
Described shank 2 is identical with bearing rod 7 length, and length is less than 1/2 piece lengths.
The radian that length under described leveling spring 5 free state is greater than base plate is high.
Described base plate 1 is greater than concrete sample height with the spacing of two cambered surfaces of top board 6.
Principle of work:
The length of side of base plate 1 is with reference to concrete sample selection of dimension, and base plate 1 length of side is greater than concrete sample length of side some scale; One group of shank 2 is welded on the bight of base plate 1 end face, surround rectangular frame, one group of bearing rod 7 is welded on the bight of top board 6 bottom surface, welding position is corresponding with one group of shank 2 of base plate 1, one group of support spring 3 two ends is enclosed within one group of shank 2 and one group of bearing rod 7 respectively, and one group of shank 2 is identical with the length of one group of bearing rod 7, and chooses with reference to the Split-tension of Rolled test specimen length of side, choose length and be less than test specimen 1/2 length of side, top board 6 will be ensured in this range scale of decline by test specimen splitting simultaneously; The radian that length under one group of leveling spring 5 free state is greater than base plate 1 is high, will ensure at concrete sample Gravitative Loads after leveling spring 5 simultaneously, and one group of leveling spring 5 decrement equals or slightly larger than this range scale; Base plate 1 is measure-alike with top board 6; At top board 6 Gravitative Loads after one group of support spring 3, base plate 1 is greater than concrete sample height certain limit with the spacing of top board 6 liang of cambered surfaces, takes out to facilitate or places test specimen.
