Description

Technical Field

[0001] This disclosure relates to the field of building material testing equipment technology, and more specifically, to a test block fixing device for a pressure testing machine. Background Technology

[0002] In the field of building materials testing, concrete, as the most commonly used building material in modern construction projects, has compressive strength as one of its most fundamental mechanical properties. By measuring the compressive strength of concrete, it is possible to assess whether the concrete meets design requirements and ensure that the building remains stable and reliable under various loads. Therefore, whether the compressive strength value of concrete meets the design requirements is particularly important.

[0003] A concrete compression testing machine is a device used to determine the compressive strength of concrete, but its use presents some inconveniences and problems. For example, when operating a current compression testing machine, concrete test blocks (including different types of test blocks such as concrete, shotcrete, and mortar) are placed on the machine platform. To ensure the accuracy of the test results, operators need to manually and repeatedly adjust the position of the concrete test blocks to ensure they are accurately aligned with the machine's axis. This manual adjustment is not only time-consuming but also prone to errors, affecting the accuracy of the test results. Furthermore, traditional methods of fixing test blocks often lack adaptability to different block sizes, making it difficult to meet the needs of test blocks of varying specifications.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0041] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0042] In related technologies, when using concrete in batches, it is necessary to test the compressive strength of the concrete. A pressure testing machine is often used to test the compressive properties of concrete. The testing procedure for concrete test blocks using a pressure testing machine is as follows: First, the concrete test block is placed on the operating platform of the pressure testing machine. The operator repeatedly adjusts the position of the concrete test block on the operating platform until the axis of the concrete test block and the output end of the testing machine are aligned. Then, the pressure testing machine is operated, and the output end of the pressure testing machine applies pressure to the concrete test block, thus achieving the pressure test. However, the step of adjusting the position of the concrete test block on the operating platform reduces the testing efficiency, and human operation also introduces certain errors, leading to a decrease in the accuracy of the concrete pressure test.

[0043] Based on this, this disclosure provides a test block fixing device for a pressure testing machine. See also... Figure 1 , Figure 2 The fixing device 1 includes a fixing base plate 11 and a limiting component 12; the pressure testing machine has a pressure platform; the fixing base plate 11 is disposed on the pressure platform; the limiting component 12 is disposed on the fixing base plate 11 and is used to restrict the test block 3 on the fixing base plate 11 so that the test block 3 and the output end of the pressure testing machine are on the same axis.

[0044] In this embodiment, when testing the concrete specimen 3, the concrete specimen 3 is placed on the fixed base plate 11, and the limiting component 12 is adjusted to restrict the concrete specimen 3 onto the fixed base plate 11. At this time, the concrete specimen 3 and the output end of the pressure testing machine are on the same axis. The pressure testing machine is then turned on, and the pressure testing machine performs pressure testing on the concrete specimen 3. In this embodiment, the limiting component 12 can quickly adjust the position of the concrete specimen 3, improving the efficiency of pressure testing of the concrete specimen 3; at the same time, it can also reduce the phenomenon of reduced testing accuracy of the concrete specimen 3 due to errors in the placement position of the concrete specimen 3.

[0045] In some embodiments of this disclosure, see Figure 1 , Figure 2 The limiting component 12 includes multiple sets of limiting plate groups 2; each limiting plate group 2 includes limiting plates 24 symmetrically arranged along the diagonal direction of the test block 3; wherein the distance between the symmetrically arranged limiting plates 24 in different limiting plate groups 2 is different. This arrangement allows the fixing device 1 to fix test blocks 3 of different specifications, thereby improving the applicability of the fixing device 1.

[0046] It is understood that in the embodiments of this disclosure, the concrete test block 3 is a regular cubic structure with a rectangular cross-section, and the diagonal direction mentioned above refers to the diagonal direction of the cross-section of the concrete test block 3.

[0047] As an example, see Figure 1 , Figure 2 The limiting component 12 may include three sets of limiting plate groups 2. For ease of understanding, in this embodiment, the limiting plate group 2 may include a first subgroup 21, a second subgroup 22, and a third subgroup 23. It should be noted that in other embodiments, the limiting component 12 may not be limited to three sets of limiting plate groups 2, and this embodiment will not elaborate on this.

[0048] The following is an explanation of the first subgroup 21, the second subgroup 22, and the third subgroup 23:

[0049] The first subgroup 21 includes a first limiting plate 24 (not shown in the accompanying drawings) symmetrically arranged along the diagonal direction of the test block 3. In some embodiments, the distance between the two first limiting plates 24 can be 70.7 mm, so that the fixing device 1 can be adapted to the test block 3 with a diagonal length of about 70.7 mm.

[0050] The second subgroup 22 includes a second limiting plate 24 (not shown in the accompanying drawings) symmetrically arranged along the diagonal direction of the test block 3. In some embodiments, the distance between the two second limiting plates 24 can be 100mm, so that the fixing device 1 can be adapted to the test block 3 with a diagonal length of about 100mm.

[0051] The third subgroup 23 includes a third limiting plate 24 (not shown in the accompanying drawings) symmetrically arranged along the diagonal direction of the test block 3. In some embodiments, the distance between the two third limiting plates 24 can be 150mm, so that the fixing device 1 can be adapted to the test block 3 with a diagonal length of about 150mm.

[0052] In summary, by setting up multiple limiting plate groups 2, it is possible to adapt to test blocks 3 of various specifications, thereby increasing the applicability of the fixing device 1. It should also be noted that the use of different limiting plate groups 2 in this embodiment is independent of each other.

[0053] Furthermore, in this embodiment of the disclosure, the limiting plates 24 in different limiting plate groups 2 are all located on the same straight line.

[0054] In some embodiments of this disclosure, see Figure 2 The limiting plates 24 in different limiting plate groups 2 have the same structure. Each limiting plate 24 includes a first plate 241 and a second plate 242; the first plate 241 is connected to the second plate 242, and the test block 3 has a first side 31 and a second side 32 connected to the first side 31; the test block 3 has a fixed state, in which the first plate 241 contacts the first side 31, and the second plate 242 contacts the second side 32. This arrangement allows the limiting plates 24, positioned along the diagonal direction of the test block 3, to achieve omnidirectional fixation of the test block 3, thus improving the fixation effect.

[0055] As an example, the first plate 241 and the second plate 242, which are connected to each other, are in an "L" shape.

[0056] In some embodiments of this disclosure, the fixed base plate 11 has a limiting groove 111 adapted to the limiting plate 24. Specifically, when it is necessary to fix a test block 3 of a certain specification, the limiting plate 24 is inserted into its corresponding limiting groove 111 (the bottom of the limiting plate 24 will contact the operating platform of the pressure testing machine, and the limiting plate 24 can be stably fixed on the fixed base plate 11). The limiting plate 24 extending beyond the fixed base plate 11 along the diagonal direction of the test block 3 forms a fixing space for the test block 3. In the embodiments of this disclosure, the insertion method used to fix the limiting plate 24 to the fixed base plate 11 can improve the testing efficiency of the test block 3; at the same time, it can also facilitate quick replacement when testing test blocks 3 of different specifications.

[0057] In some embodiments of this disclosure, the limiting plate 24 has a protrusion 243 on the side near the test block 3, and the protrusion 243 and the side of the limiting plate 24 near the test block 3 form an anti-slip space. The protrusion 243 facilitates the operator to pull out or insert the limiting plate 24 into the limiting groove 111, thereby improving the testing efficiency of the test block 3 to a certain extent.

[0058] As an example, see Figure 3 , Figure 4 The limiting component 12 includes a fixing block 121, a connecting spring 122, and a clamping member 123 symmetrically arranged along the width direction of the fixing base plate 11. The fixing block 121 is rotatably connected to the fixing base plate 11, and the opposing fixing blocks 121 form a clamping space for the test block 3. One end of the connecting spring 122 is connected to the fixing block 121 on one side, and the other end is connected to the fixing block 121 on the other side. The movement direction of the connecting spring 122 is perpendicular to the axis of rotation between the fixing block 121 and the fixing base plate 11. The clamping member 123 is used to push the test block 3 on the fixing base plate 11 into the clamping space. Specifically, when it is necessary to fix the test block 3 on the fixed base plate 11, the test block 3 is placed on the fixed base plate 11, the clamping member 123 is adjusted, the clamping member 123 drives the test block 3 to move on the fixed base plate 11, the test block 3 enters the clamping space, and under the action of the connecting spring 122, the two fixing blocks 121 are driven to approach the side wall of the test block 3 to achieve clamping and fixing of the test block 3.

[0059] See in this example. Figure 3 , Figure 4 The fixing block 121 has a fixing groove 1211 on the side near the test block 3; the fixing groove 1211 has a first groove segment 12111 and a second groove segment 12112; the test block 3 is in a fixed state, and in the fixed state, the first groove segment 12111 and the second groove segment 12112 are in contact with two adjacent side walls of the test block 3. The clamping member 123 includes a clamping block 1231 and a clamping rod 1232; the clamping block 1231 is disposed on the fixing base plate 11; the clamping rod 1232 is rotatably connected to the clamping block 1231, the axial direction of the clamping rod 1232 is perpendicular to the movement direction of the connecting spring 122, and the end of the clamping rod 1232 can contact the side wall of the test block 3 away from the fixing block 121. Specifically, when it is necessary to clamp and fix the test block 3 on the fixed base plate 11, rotate the clamping rod 1232. The clamping rod 1232 drives the test block 3 into the clamping space. At this time, the two fixed blocks 121 are far apart from each other. When the test block 3 enters between the two fixed blocks 121, under the action of the connecting spring 122, the two fixed blocks 121 move closer to each other, thereby fixing the test block 3 on the fixed base plate 11.

[0060] Furthermore, in this example, see Figure 3 , Figure 4The limiting component 12 also includes a movable rod 125 and a fixing bolt 124. The movable rod 125 is slidably connected to the fixed base plate 11, and the direction of movement of the movable rod 125 is the same as the axial direction of the connecting spring 122. The fixing block 121 is sleeved on the movable rod 125. The fixing bolt 124 is threadedly connected to the movable rod 125 and can contact the fixed base plate 11 to fix the movable rod 125 to the fixed base plate 11. Specifically, when pressure testing is performed on test blocks 3 of different specifications, the movable rod 125 is operated, and the movable rod 125 slides on the fixed base plate 11. After the movable rod 125 moves to a suitable position, the fixing bolt 124 is rotated, and the fixing bolt 124 approaches the fixed base plate 11 and abuts against the fixed base plate 11 to fix the movable rod 125.
