Technical field
The present invention relates to the device of hardened mortar intensity in a kind of indoor test masonry, particularly the tester of mortar strength.
Background technology
Masonry mortar is the Important building material in masonry structure, and its intensity is normally evaluated according to the compressive strength of the standard cube body test block of reserving.But when mortar specimen lacks representativeness or test block lazy weight, perhaps with suspicion or disputable to the test findings of mortar specimen, or the test findings of mortar specimen be can not meet design requirement the time, all needs to adopt the field test method to mortar and masonry strength carries out in situ detection or sampling detects.The impact screen point-score is the method for testing more widely mortar strength of using at present, test block destroys to hardened mortar by utilizing ballistic work, make its fragmentation, after broken, long-pending increment and the mortar compressive strength of test block surface is inverse ratio, it is more to be that the surface area that causes of specific work increases, and mortar compressive strength is lower.And the Apparatus for Impacting at low-temp that present domestic use ballistic method detects mortar strength is generally the YJ-1 type Apparatus for Impacting at low-temp of Metallurgical Research Institute, Department of Architecture development.This Apparatus for Impacting at low-temp exists following shortcoming to be: when (1) adjusts shock height, striker need to be moved to target gauge length hole from gauge length hole, place, thereby reduce work efficiency; (2) the claw part-structure is comparatively complicated, and easily wearing and tearing are difficult for repairing, and the spring of especially controlling the claw opening and closing easily distortion loses function; (3) shock height is difficult for Measurement accuracy.
Summary of the invention
The object of the invention is to solve the Apparatus for Impacting at low-temp inefficiency under prior art, the problem that shock height is measured out of true and claw part-structure complexity.
The objective of the invention is to be achieved by the following technical programs:
The tester of mortar strength is characterized in that comprising: base, and base one side is provided with column, and column one side is provided with the main chute with scale, and main chute is provided with the master slider that is slidably matched with it, and master slider is fixed by bolt-locking; The column epimere is provided with connecting rod, the connecting rod other end is provided with through hole, be connected with the guide rod that is slidably matched with it in through hole, guide rod is provided with the electromagnet of tape relay, one side of the electromagnet of tape relay is provided with limit switch, limit switch forms the location with master slider and coordinates, and electromagnet and the guide rod of tape relay are slidably matched; The below of the electromagnet of tape relay is provided with weight, and weight and guide rod are slidably matched; Base is provided with sleeve, and the center line of sleeve overlaps with the center line of guide rod.
On the basis of technique scheme, following further technical scheme can also be arranged:
The column stage casing is connected with substrate, hinged arc support on substrate, and the electromagnet epimere of tape relay is provided with fixed orifice, and fixed orifice can form to support with arc support and fix.
The connecting rod other end also is provided with secondary slide block, also is provided with pilot hole on guide rod, and pilot hole forms the location with secondary slide block and coordinates.
On the cylindrical of sleeve, uniform one group of bolt, be provided with barrel in sleeve, and barrel outer wall and sleeve are fixed by bolt-locking.
The electromagnet upper end of described tape relay is provided with handgrip, so that the operator uses.
The quality of described weight and the positioning height of master slider have determined the size of impulsive force, and it should suitably be adjusted according to actual conditions.
Beneficial effect of the present invention is simple in structure, easy operating, can accurately measure fast shock height, and improve work efficiency.
Following constipation closes drawings and Examples, and the present invention is further described.
