Abstract
The utility model discloses a kind of concrete crushing strength and measure test specimen locating device, comprise casing and steel backing plate, steel backing plate is fixed on casing, the upper surface of steel backing plate is provided with the locating slot for positioning concrete sample to be measured, and four sides of casing are provided with the jackscrew of the center for regulating locating slot.The utility model can realize the quick position of concrete crushing strength test block.
Description
Technical field
The utility model relates to a kind of locating device, is specifically related to a kind of concrete crushing strength and measures test specimen locating device.
Background technology
Concrete crushing strength is the important technology index of evaluation concrete quality, concrete crushing strength test all generally adopts in the engineerings such as building, water conservancy, bridge, railway, harbour, tunnel, and the one day concrete test block compressive strength test amount in some laboratories reaches more than hundreds of block.
Concrete crushing strength adopts pressure testing machine to test usually, in standard GB/T/T50081-2002 " standard for test methods of mechanical properties of ordinary concrete ", regulation concrete crushing strength test specimen is cube, its length of side can be 100mm, 150mm or 200mm, often organizes three pieces.Require during intensity test to adopt cube specimen two sides (non-forming face) as compression face, test specimen center must be aimed at bearing plate center under pressing machine, namely test specimen is axial compression, if centering is forbidden, eccentric compression will be become, make the compression strength value of concrete sample obviously on the low side, cause concrete bearing intension testing value to occur remarkable deviation.Under general pressure testing machine, bearing plate is carved with donut or cross spider, test specimen whether centering is judged when testing for helping experimenter, if four summits of cube specimen and lower bearing plate surface of contact are all circumferentially same or all on cross spider, then show test specimen centering, otherwise should adjust, but the method needs testing crew to lean on naked eyes carefully conscientiously to distinguish, and whether test specimen is in Shaft alignment state, the human users's skill level that is put to the test and attention degree affect very large, when testing, test specimen quantity is many, when operating personnel lack a sense of responsibility, concrete sample eccentric compression is often caused to destroy, test figure discreteness increases, even causing cannot qualification test result.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of concrete crushing strength and measures test specimen locating device, and this device can realize the quick position of concrete crushing strength test test specimen.
For achieving the above object, concrete crushing strength described in the utility model measures test specimen locating device and comprises casing and steel backing plate, steel backing plate is fixed on casing, the upper surface of steel backing plate is provided with the locating slot for positioning concrete sample to be measured, and four sides of casing are provided with the jackscrew of the center for regulating locating slot.
The thickness of described steel backing plate is more than or equal to 25mm.
Described locating slot is the square structure of openings at one side, and the upper surface of steel backing plate is all fixed on other three limits of locating slot.
The wall thickness of locating slot is 5-10mm, and the wall height of locating slot is 1mm.
The length of side in the region that described square structure surrounds is 100mm, 150mm or 200mm.
The gross thickness of described casing and steel backing plate is 50-100mm.
