Description

Technical Field

[0001] The utility model belongs to the technical field of concrete performance testing instruments, and in particular relates to a concrete splitting testing device which is convenient for collecting waste materials. Background Art

[0002] Concrete splitting tensile strength is an important performance index of concrete, which is the tensile load required for unit bonding width when the concrete bonded specimen separates. The current test method for concrete splitting tensile strength is: first draw parallel straight lines in the middle of the top and bottom surfaces of the specimen when it is formed, then place the specimen at the center of the lower platen of the pressure testing machine, and pad between the upper and lower plates and the test block (the direction of the pad should be perpendicular to the top surface when formed), and finally continuously and evenly load at a certain rate until the specimen is destroyed, record the failure load, and calculate the splitting tensile strength.

[0003] In current practice, when conducting a splitting test on a concrete cube specimen, the position line of the splitting surface must first be drawn on the specimen, and then the specimen and the padding strip must be placed on the pressure testing machine, and the specimen must be geometrically aligned so that the splitting surface is perpendicular to the pressure direction. Since the padding strip and the specimen are placed directly on the press manually, it is easy for the splitting surface to be non-perpendicular to the pressure direction, affecting the test accuracy; moreover, in the concrete splitting test, the concrete will be subjected to the huge pressure of the press, and after the concrete collapses, its debris is easy to splash everywhere, thereby injuring the test personnel or damaging other instrument settings and other devices, and it is also inconvenient to collect and clean up the broken waste.

[0004] Therefore, a concrete splitting test device which is convenient for collecting waste is proposed. Utility Model Content

[0014] Compared with the prior art, the utility model has the following advantages and technical effects:

The pressure assembly is controlled by the controller to slowly pressurize, and the force on the sample is recorded at all times.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1 to 4 As shown, this embodiment provides a concrete splitting test device for convenient waste collection, including: an implementation mechanism and a controller 2, the controller 2 is electrically connected to the implementation mechanism; the implementation mechanism includes a test box 3, the front end of the test box 3 is open, and the front end of the test box 3 is hinged with an opening and closing door 4; a collecting box 5 is placed on the bottom surface of the test box 3, the collecting box 5 is annular, and the inner side of the collecting box 5 is abutted with a base 6, the base 6 is placed on the test box 3, and a clamping assembly for clamping a sample 1 is detachably connected to the base 6, centering assemblies are arranged on both sides of the clamping assembly, and a pressurizing assembly is arranged on the top of the clamping assembly.

[0025] The controller 2 is placed on the side of the implementation mechanism and is used to control the test activities of the implementation mechanism. Before the test, a collection box 5 is placed at the bottom of the test box 3, and a support 6 is placed inside the collection box 5. The sample 1 is clamped in the clamping assembly, and then the clamping assembly holding the sample 1 is placed on the support 6. The centering assembly is started to squeeze the sample 1 from both sides to align the line of action of the sample 1 and the pressure assembly force. The pressure assembly is then slowly lowered to apply pre-pressure to the clamping assembly to fix the position of the sample 1, and then the opening and closing door 4 is closed. The pressure assembly is controlled by the controller 2 to slowly pressurize, and the force on the sample 1 is recorded at all times. While the pressure assembly is pressurizing, the centering assembly needs to be controlled to stay away from the sample 1 to avoid the pressure of the centering assembly on the sample 1 affecting the experimental results. As the pressure of the pressurizing component increases, the sample 1 is split, and the generated debris is blocked by the test box 3 and the opening and closing door 4 so that it will not splash everywhere, and will eventually fall into the collection box 5; after the test, the pressurizing component can be lifted, the clamping component releases the clamping of the sample 1, the sample 1 is removed, and the debris that may remain on the clamping component is swept into the collection box 5, the clamping component is removed, the support 6 is removed, and the collection box 5 is removed, and the debris in the collection box 5 and the cracked sample 1 can be collected and cleaned. During the concrete splitting test, the utility model can ensure that the splitting surface is perpendicular to the pressure direction by aligning the centering component; the opening and closing door 4 and the test lower box prevent the splitting debris from splashing, and the waste materials such as the splitting debris can be conveniently collected through the collection box 5, which is convenient for cleaning and recycling.

[0026] According to a further optimized solution, the inner wall of the collecting box 5 abuts against the outer surface of the support platform 6 , and the outer wall abuts against the inner wall of the testing box body 3 and the inner wall of the opening and closing door 4 .

[0027] The collecting box 5 fills the gap between the support platform 6 and the inner wall of the testing box body 3, and can completely collect the fallen debris.

[0028] To further optimize the solution, the opening and closing door 4 is embedded with glass.

[0029] The glass facilitates observation of the interior of the test box 3 after the opening and closing door 4 is closed.

[0030] A further optimized solution is provided, in which the clamping assembly comprises an upper clamping plate 7 and a lower clamping plate 8. An upper pad 9 is fixedly connected to the bottom center of the upper clamping plate 7, and a lower pad 10 is fixedly connected to the lower clamping plate 8 corresponding to the upper pad 9; sleeves 11 are fixedly connected to the four corners of the upper clamping plate 7, and sliding columns 12 are fixedly connected to the sleeves 11 around the lower clamping plate 8 corresponding to the sleeves 11, and the sliding columns 12 are slidably connected to the sleeves 11; gaskets 19 are abutted between the upper pad 9 and the sample 1, and between the lower pad 10 and the sample 1.

[0031] The sliding column 12 is slidably connected in the sleeve 11, limiting the moving path of the upper clamping plate 7 to up and down movement, and the sample 1 is clamped between the upper pad 9 and the lower pad 10;

[0032] According to a further optimized solution, both the upper pad 9 and the lower pad 10 are arc-shaped pads, and their axes are perpendicular to the centering assembly.

[0033] The arc-shaped pad is set so that the contact between the pad and the sample 1 is a line contact, and the force applied by the pressurizing component can be concentrated on the contact line, which is conducive to the splitting of the sample 1.

[0034] According to a further optimized solution, positioning columns 13 are fixedly connected to the four corners of the bottom of the lower clamping plate 8 , and positioning grooves 14 are provided on the top of the support platform 6 corresponding to the positioning columns 13 .

[0035] The positioning column 13 is inserted into the positioning groove 14 to fix the position of the support platform 6 and prevent the support platform 6 from being offset outward.

[0036] According to a further optimized solution, the centering assembly includes hydraulic telescopic rods 15 symmetrically fixed to two sides of the test box 3 , and the inner side of the hydraulic telescopic rods 15 is a movable end fixed with an abutment block 16 .

[0037] The hydraulic telescopic rods 15 on both sides are symmetrically arranged and can extend inward together to squeeze the sample 1 from both sides. The center of the sample 1 can be determined at the symmetrical center of the two hydraulic telescopic rods 15.

[0038] According to a further optimized solution, the pressurizing assembly includes a hydraulic cylinder 17 , which is fixedly connected to the top of the test box 3 corresponding to the support platform 6 , with the movable end of the hydraulic cylinder 17 facing downward, and a pressure plate 18 fixedly connected to the movable end of the hydraulic cylinder 17 .

[0039] The hydraulic cylinder 17 is controlled by the controller 2 and applies downward pressure on the sample 1 through the pressure plate 18 .

[0040] Furthermore, when the distance between the pressing plate 18 and the upper clamping plate 7 is far, a pressing block can be placed between the upper clamping plate 7 and the pressing plate 18 to shorten the distance between the upper clamping plate 7 and the pressing plate 18 to avoid the hydraulic cylinder 17 having a too short range and failing to split the sample 1.
