Abstract
The utility model relates to a masonry mortar strength point load tester, composed of a tester frame, a loading system, and a force measuring system. The utility model is characterized in that the tester frame comprises a base, an upright column, and an upper cover plate; a pressure sensor of the force measuring system is arranged and fixed on the base of the tester frame, and the force measuring display system is connected with the pressure sensor through a conductor wire; the loading system comprises a loading hand wheel, an upper point and a lower point loading type loading heads. The strength tested by the utility model can satisfy the strength grade of usual mortar. The utility model is especially suitable for testing low strength mortar, and has the advantages of high-speed test, accurate reading, no water and electricity, manual loading, and liquid crystal display peak holding. The utility model is suitable for testing the strength of the masonry mortar in construction job location.
Description
The utility model relates to a kind of building operation instrument, particularly can be used for the testing tool of on-site measurement masonry mortar intensity.
Masonry mortar strength test in the past all is to get mortar specimen to test in testing laboratory, adopts the Amseler200KN testing machine to carry out, and when using the small oil tank of this testing machine, fully loaded is 20KN.The failing load of mortar strength point lotus method of testing is generally at 0.5KN～1KN, and when masonry mortar intensity was low, the failing load value was lower, sometimes 0.1KN～0.2KN only.Therefore use the Amseler testing machine, be difficult for accurately measuring the failing load value, should not be used to measure the lower mortar of intensity especially; And this mode can't be tested at the scene.
The purpose of this utility model is, a kind of novel masonry mortar hot spot lotus tester is provided, and its test intensity can satisfy the test of using strength classes of mortar always, particularly measures the low-intensity mortar, and can satisfy the requirement of on-the-spot test, uses easy to operate.
Masonry mortar hot spot lotus tester of the present utility model is made up of instrument support, loading system, dynamometric system, it is characterized in that:
Instrument support comprises base, column and upper cover plate;
Dynamometric system comprises pressure transducer and dynamometry display system, and pressure transducer is fixed on the base of instrument support, and the dynamometry display system is connected with pressure transducer by lead;
Loading system comprises rotation loading handwheel and upper and lower some lotus formula loading head, rotation loading handwheel is connected with the instrument support upper cover plate by screw rod, last loading head is installed in the screw rod end, following loading head replace be installed in pressure transducer add the compressing tablet place, loading head is an intercept sphere.
The column of described instrument support can adopt two～four.
In the described loading system, last loading head is a steel ball, is stuck in the end of screw rod, and centering is more accurate during this structural test.
In the described loading system, there is a circle groove end that connects the screw rod of handwheel, by three screws one set collar is fixed on the termination of screw rod, and a thrust bearing is set in set collar, loading head on the interception shape, the loading head scalable of this structure are installed in bottom at set collar.
Masonry mortar hot spot lotus tester of the present utility model owing to adopt metal support, can guarantee the strength and stiffness of instrument stand; The pressure transducer that dynamometric system adopts is the BHR-4/300 resistance-strain load sensor of last marine products, its test specification is 0～3000N, can satisfy the requirement of the some lotus test of masonry mortar intensity commonly used, dynamometry display system in the dynamometric system adopts the SC-2 digital peak table of Construction Structure Inst., Chinese Construction Science Research Inst's development and production, it has the function that the load peak value keeps, so that record; Loading head in the loading system adopts intercept sphere, when can guaranteeing to test, it applies concentrated " point " formula load on load-bearing face, the area load that replaces conventional intensity test to use, make its test condition less demanding to test specimen, and the test strength range is big and test is accurate, be to guarantee the hardness of loading head, loading head is selected No. 45 steel or 40 chromium steel for use, and heat-treats.
Masonry mortar hot spot lotus tester use-pattern of the present utility model is: take out the mortar sheet as sample from the masonry that has puzzled, be placed on up and down between the loading head of masonry mortar hot spot lotus tester, rotate handwheel by hand and make up and down that loading head contacts with mortar specimen, continue rotation hand wheel mortar specimen is applied the point type load, applied pressure is delivered to the peak value meter of dynamometry display system by pressure transducer, destroys until mortar specimen.By reading a lotus value on the peak value meter, calculate the compressive strength of masonry mortar according to experimental formula.
It is simply light and handy that this instrument has an instrument, test fast, accuracy of reading does not need water power, manually loading, the liquid crystal display peak value keeps, the measuring accuracy height is fit to construction site to the masonry mortar strength test.
Below in conjunction with drawings and Examples, masonry mortar hot spot lotus tester is described further.
