Abstract
The utility model discloses a special equipment instrument for testing the pressive strength and the tensile strength of the building materials in the building trade. According to the theory that the vertical and the parallel diagonal lines can change the distance when the rhombus is pressed, the utility model designs pressing blocks and tensile blocks into the rhombus structure, and the pressure between the two pressing blocks can be changed into the pressure between the two tensile blocks to realize the integrated display of the pressure, the tensile force and the digit to test the pressive strength and the tensile strength of the building materials. The utility model has the advantages of small size, light weight, low cost, high efficiency and less man made fault when used.
Description
The utility model relates to the building materials test of construction work system, the specialized instrument and equipment of the test of concrete test block compressive strength and reinforcing bar tensile strength.
At present, general pressure and the tension tester function of using of building trade is single, comparatively advanced is to adopt the pressure of digital hydraulic combination to draw testing machine, and this machine still need overlap physical constructions with two, and volume is big, on the other hand, in the time of workman's operation, the oil pipe of converting, the easy blocking pipeline of test block disintegrating slag, mechanical disorder is many, inconvenient operation.
The purpose of this utility model provides a kind of to the building materials resistance to compression, the test machines instrument and equipment of tension dual-use function, and it can effectively reduce mechanical fault, alleviates the weight reduced volume of equipment, and handled easily ， And can increase work efficiency.
The technical solution of the utility model is achieved in that the preceding pulling block of upper holder block, lower lock block and the tension tester of pressure testing machine, back pulling block is formed a diamond structure by connecting rod and latch, semicircle slide block and two pillars by two limits about upper and lower briquetting are done movingly, can be along the upper and lower slip of pillar.End face at lower lock block is connected with lifting jack, makes lower lock block produce pressure by lifting jack, finishes the test of concrete test block compressive strength.Simultaneously, because the stressed reason that makes vertical and parallel diagonal line shorten and extend of the length of side of rhombus can make the pressure between upper and lower briquetting become the pulling force of forward and backward pulling block by connecting rod, thereby can do the test of tensile strength to structural steel.Make it to have resistance to compression, the dual-use function of test for tensile strength to building materials.
By connection rod set diamondwise structure, little, the low cost of manufacture of machine volume reaches a tractor serves several purposes to the utility model like this upper and lower briquetting and forward and backward pulling block, and lifting jack replaces oil pump, mechanical fault minimizing, have easy to operate, the advantage that testing efficiency is high.
The utility model structure is further described in conjunction with the accompanying drawings:
Fig. 1 is the utility model physical construction synoptic diagram.
Diamond structure comprises upper holder block 16, lower lock block 12, preceding pulling block 13, back pulling block 4 and connecting rod 15.8 connecting rods 15 are as the limit of rhombus, two end faces in the front and back of one end and upper holder block 16, lower lock block 12 are fixed by latch, do flexible connection, hold about the other end and preceding pulling block 13, back pulling block 4 and fix by latch, do flexible connection, two briquettings of whole rhombus and two pulling blocks can about, the front and back displacement, change distance between upper holder block 16 and the lower lock block 12 and preceding pulling block 13 and the back distance between the pulling block 4, generation pressure and pulling force.Semi-circular slide block 6 by fixed screw 9 be fixed on upper holder block 16 and lower lock block 12 about on two end faces, do movingly with two pillars, lower lock block can be moved up and down.Upper holder block 16 planes have two fixing threaded holes 20 and centre bit thereof to be equipped with a pressure transducer pickup groove 19.Fixed bar is connected between standing screw hole 20 and the crossbeam, fixedly upper holder block 16 and pressure transducer.The lower plane centre bit of lower lock block 12 has a lifting jack pickup groove 21.Be shaped on spill sphere hole 14 at preceding pulling block 13.
Fig. 2 describes the utility model resistance to compression, tensile test embodiment.
Resistance to compression embodiment, start the lifting jack 10 that is fixed on lifting jack pickup groove on the support 11, its firm lower lock block 12 in top, upper end, lower lock block 12 makes lower lock block 12 steady, risings uniformly by the semi-circular slide block 6 of left and right sides biend movingly with two pillars 3 that are connected 18 on support 11 and crossbeam, pressure to the test block generation, And imports pressure signal in the secondary instrument case 1 by the pressure transducer 17 of upper holder block fixed bar 2 fix tightlies between pressure transducer pickup groove 19 through being placed on upper holder block 16 and the crossbeam 18, handle through Microcomputer Detecting, obtain pressure value.
Tension embodiment: an end is fixed on the pulling force sensor of back on the pulling block 4 is connected with spill sphere hole 14 by termination ball screw rod by wire clamp 8, they keep movingly, can be before normal moveout correction the concentricity of pulling block 13 and back pulling block 4.Lower lock block 12 rises and makes preceding pulling block 13 and back pulling block 4 displacements change distance, produces pulling force, imports in the secondary instrument case 1 by pulling force sensor, through the Microcomputer Detecting processing, shows building materials tensile strength.
