Description

Technical Field

[0001] This application relates to the field of masonry mortar testing, and in particular to a mechanical probe device for testing the strength of masonry mortar in layers. Background Technology

[0002] In actual masonry construction, factors such as uneven mortar mixing and inconsistent mortar thickness during construction may lead to uneven strength distribution of the masonry mortar in the vertical direction.

[0003] Existing testing methods mainly include the penetration test and the rebound test. The penetration test usually uses a penetrator to press a standard-sized cone into the mortar surface and estimate the compressive strength of the mortar based on the penetration depth. This method is simple and easy to implement, but it has obvious limitations in the detection depth. It can generally only detect the strength of the mortar a few millimeters deep from the surface. The rebound test uses a rebound hammer to tap the mortar surface and estimates the hardness of the mortar based on the rebound value. It also has the problem of shallow detection depth. Neither of these two methods can provide strength data at different depths inside the mortar. Therefore, they have significant limitations in comprehensively assessing mortar quality and discovering deep-seated quality problems.

[0004] The main drawback of existing testing methods is that they can only test the strength within a certain depth range on the surface of mortar, and cannot deeply understand the true strength of each layer inside the mortar. This limitation makes it difficult to detect some potential quality problems in a timely manner, posing risks to the safety and durability of building structures. Utility Model Content

[0005] The purpose of this application is to address the main shortcomings of existing testing methods mentioned in the background art, which are that they can only detect the strength within a certain depth range of the mortar surface and cannot deeply understand the true strength of each layer inside the mortar. This limitation makes it difficult to detect some potential quality problems in a timely manner, posing a risk to the safety and durability of building structures. This application provides a mechanical probe device for layered strength testing of masonry mortar.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A mechanical probe device for testing the strength of masonry mortar in layers includes a support base, an abutment frame on the support base, four symmetrically arranged support frames between the abutment frame and the support base, both ends of the support frame being fixedly connected to the support base and the abutment frame, a probe on the support base, a mechanical pressure gauge on one side of the probe, a moving mechanism between the probe and the support base, and a connecting mechanism on the probe.

[0008] By adopting the above technical solution, the contact frame is firmly pressed against the wall surface. Then, the moving mechanism drives the probe to move and insert it into the masonry mortar. During the movement of the probe, the pressure on the probe is transmitted to the mechanical pressure gauge. The value on the mechanical pressure gauge is used to determine the strength inside the masonry mortar. This allows for layered strength testing of the masonry mortar, providing a comprehensive understanding of the strength distribution at different depths within the mortar. This effectively overcomes the limitations of traditional testing methods, improves the accuracy and reliability of the testing, reduces the influence of human factors, and ensures that the test results are true and reliable.

[0009] Furthermore, the moving mechanism includes a threaded rod disposed on a support base, the threaded rod passing through the support base and slidably connected to the support base, a support block fixed to one end of the threaded rod near the probe, a sliding component disposed on the support block, and a driving component disposed between the support base and the threaded rod.

[0010] By adopting the above technical solution, the drive component drives the threaded rod, which moves on the support seat under the restriction of the sliding component, allowing the probe to penetrate into the masonry mortar. This enables layered strength testing of the masonry mortar, providing a comprehensive understanding of the strength distribution at different depths within the mortar.

[0011] Furthermore, the drive assembly includes a worm gear rotatably connected to a support base, a threaded rod passing through the worm gear and threadedly connected to the worm gear, and a worm engaging with the worm gear.

[0012] By adopting the above technical solution, the worm rotates, which drives the worm wheel to rotate, and the worm wheel drives the threaded rod to move on the support base, thus making it easy for the threaded rod to move on the support base.

[0013] Furthermore, both ends of the worm gear are rotatably connected to fixed blocks, and the fixed blocks are fixedly connected to support seats. A rocker arm is rotatably connected to one of the support seats, and the rocker arm passes through the fixed block and is fixedly connected to the worm gear.

[0014] By adopting the above technical solution, the rocker arm is rotated, which drives the worm gear to rotate, thus making it easy for the worm gear to drive the worm wheel to rotate.

[0015] Furthermore, a sleeve is fitted onto the rocker arm, and the sleeve is rotatably connected to the rocker arm.

[0016] By adopting the above technical solution, one can hold the sleeve and then drive the sleeve to rotate the rocker arm, thus making it easy to rotate the rocker arm.

[0017] Furthermore, the sliding assembly includes two symmetrically fixed connecting rods on the support block, with a sliding block fixed on each connecting rod. Two symmetrical sliding rails are fixed between the support base and the contact frame, and the sliding block is slidably connected to the sliding rail.

[0018] By adopting the above technical solution, when the threaded rod drives the support block to move, the support block drives the connecting rod, and the connecting rod drives the sliding block to move on the sliding rail, thereby preventing the threaded rod and the support block from rotating and allowing the probe on the support block to be smoothly inserted into the masonry mortar.

[0019] Furthermore, the connecting mechanism includes a connecting seat fixed on the support block, the connecting seat having a snap-fit ​​groove, one end of the snap-fit ​​groove being open, the connecting seat having a snap-fit ​​block located in the snap-fit ​​groove and slidably connected to the connecting seat, and the mechanical pressure gauge being fixedly connected to the connecting seat.

[0020] By adopting the above technical solution, the snap-fit ​​block is inserted into the snap-fit ​​groove on the connector, which makes it easy to replace different probes and adapt to different masonry mortar depths.

[0021] Furthermore, a fixing bolt is threaded onto the connecting seat, the fixing bolt passing through the connecting seat and abutting against the snap-fit ​​block.

[0022] By adopting the above technical solution, the snap-fit ​​block is inserted into the snap-fit ​​groove, and the fixing bolt is rotated to abut against the snap-fit ​​block, thereby facilitating the fixing of the snap-fit ​​block and the fixing of the probe.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application describes a method for using a probe device. First, the contact frame is placed against the wall, with the probe aligned with the mortar. Then, the sleeve on the rocker arm is held, and the rocker arm is rotated. This causes the rocker arm to drive the worm gear, which in turn drives the worm wheel to rotate on the support base. Under the limiting influence of the sliding block and connecting rod, the support block and threaded rod maintain stable sliding. The worm wheel drives the threaded rod to move, which in turn drives the support block. The support block then drives the probe, which penetrates into the mortar layer. As the probe penetrates deeper, the reading on the mechanical pressure gauge changes. The strength of the mortar is determined based on the reading on the mechanical pressure gauge. This method enables layered strength testing of the mortar, providing a comprehensive understanding of the strength distribution at different depths within the mortar. It effectively overcomes the limitations of traditional testing methods, improves the accuracy and reliability of the test, reduces the influence of human factors, and ensures the authenticity and reliability of the test results.

[0025] 2. In this application, when the length of the probe does not match the depth of the masonry mortar to be tested, the fixing bolt is directly rotated to disengage it from the locking block. Then, the locking block on the probe is slid out of the locking groove on the connector. The corresponding probe and locking block are then replaced, and the locking block on the new probe is inserted into the locking groove on the connector. Finally, the fixing bolt is tightened again so that it contacts the locking block. This achieves the purpose of easily replacing different probes and adapting to different masonry mortar depths.

[0031] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.

[0032] This application discloses a mechanical probe device for testing the strength of masonry mortar in layers.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A mechanical probe device for testing the strength of masonry mortar in layers includes a support base 1, a contact frame 3 on the support base 1, four symmetrical support frames 2 between the contact frame 3 and the support base 1, both ends of the support frame 2 being fixedly connected to the support base 1 and the contact frame 3, a probe 4 on the support base 1, a mechanical pressure gauge 7 on one side of the probe 4, a moving mechanism 5 between the probe 4 and the support base 1, and a connecting mechanism 6 on the probe 4.

[0034] When using this testing device, first, place the contact frame 3 against the wall surface to be tested, ensuring the probe 4 is directly facing the mortar. Then, place it against the support base 1, causing the support base 1 to press against the support frame 2, which in turn presses against the contact frame 3, firmly securing the contact frame 3 against the wall surface. Next, use the moving mechanism 5 to move the probe 4, allowing it to insert into the mortar. During the movement of the probe 4, the pressure on it is transmitted to the mechanical pressure gauge 7. The reading on the mechanical pressure gauge 7 is used to determine the strength within the mortar. If the depth of the mortar does not match the probe 4, the probe 4 will be directly inserted into the wall surface. The probe 4 is removed using the connecting mechanism 6, and then replaced with a probe 4 of appropriate length for testing. The support frame is pressed against the wall, and the probe 4 is positioned against the masonry mortar. Driven by the moving mechanism 5, the probe 4 is inserted into the masonry mortar, and the corresponding pressure value is displayed on the mechanical pressure gauge 7. This allows for layered strength testing of the masonry mortar, providing a comprehensive understanding of the strength distribution at different depths within the mortar. This effectively overcomes the limitations of traditional testing methods, improves the accuracy and reliability of the test, reduces the influence of human factors, and ensures the authenticity and reliability of the test results.

[0035] Reference Figure 1 and Figure 2 The moving mechanism 5 includes a threaded rod 52 disposed on the support base 1. The threaded rod 52 passes through the support base 1 and is slidably connected to the support base 1. A support block 51 is fixed to one end of the threaded rod 52 near the probe 4. A sliding component 54 is disposed on the support block 51. A driving component 53 is disposed between the support base 1 and the threaded rod 52.

[0036] In addition, the drive assembly 53 includes a worm gear 531 rotatably connected to the support base 1, a threaded rod 52 passing through the worm gear 531 and threadedly connected to the worm gear 531, and a worm 532 meshing with the worm gear 531.

[0037] Furthermore, both ends of the worm gear 532 are rotatably connected to a fixing block 533, which is fixedly connected to the support base 1. A rocker arm 534 is rotatably connected to one of the support bases 1. The rocker arm 534 passes through the fixing block 533 and is fixedly connected to the worm gear 532.

[0038] Furthermore, a sleeve 535 is fitted onto the rocker arm 534, and the sleeve 535 is rotatably connected to the rocker arm 534.

[0039] Furthermore, the sliding assembly 54 includes two symmetrical connecting rods 543 fixed on the support block 51, and a sliding block 542 is fixed on the connecting rod 543. Two symmetrical sliding rails 541 are fixed between the support base 1 and the contact frame 3, and the sliding block 542 is slidably connected to the sliding rail 541.

[0040] When using the probe 4 device, first place the contact frame 3 against the wall, aligning the probe 4 with the mortar. Then, hold the sleeve 535 on the rocker arm 534 and rotate the rocker arm 534. This causes the rocker arm 534 to drive the worm gear 532, which in turn drives the worm wheel 531 to rotate on the support base 1. Under the limiting effect of the sliding block 542 and the connecting rod 543, the support block 51 and the threaded rod 52 maintain stable sliding. The worm wheel 531 drives the threaded rod 52 to move, which in turn drives the support block 51. The support block 51 then drives the probe 4, causing the probe 4 to penetrate. As the probe 4 penetrates deeper into the mortar layer, the reading on the mechanical pressure gauge 7 changes. The strength of the mortar is determined based on the reading on the mechanical pressure gauge 7. By having the threaded rod 52 drive the probe 4 on the support block 51 to penetrate into the mortar, the probe 4 can detect the internal strength of the mortar. This allows for layered strength testing of the mortar, providing a comprehensive understanding of the strength distribution at different depths within the mortar. This effectively overcomes the limitations of traditional testing methods, improves the accuracy and reliability of the testing, reduces the influence of human factors, and ensures the authenticity and reliability of the test results.

[0041] Reference Figure 1 and Figure 2 The connecting mechanism 6 includes a connecting seat 61 fixed on the support block 51. The connecting seat 61 has a snap-fit ​​groove 63, one end of which is open. The connecting seat 61 is provided with a snap-fit ​​block 62, which is located in the snap-fit ​​groove 63 and is slidably connected to the connecting seat 61. The mechanical pressure gauge 7 is fixedly connected to the connecting seat 61.

[0042] In addition, a fixing bolt 64 is threaded onto the connecting seat 61. The fixing bolt 64 passes through the connecting seat 61 and abuts against the snap-fit ​​block 62.

[0043] When the length of probe 4 does not match the required depth of masonry mortar, simply rotate the fixing bolt 64 to disengage it from the locking block 62. Then, slide the locking block 62 on probe 4 out of the locking groove 63 on the connecting seat 61. Replace the probe 4 with the corresponding locking block 62, insert the locking block 62 on the new probe 4 into the locking groove 63 on the connecting seat 61, and then tighten the fixing bolt 64 again so that it abuts against the locking block 62. By fixing probe 4 to the locking block 62, when probe 4 needs to be replaced, simply use the locking block 62 to remove probe 4 from the connecting seat 61, and then replace it with a new probe 4 and locking block 62. This allows for easy replacement of different probes 4 to accommodate different masonry mortar depths.

[0044] Working principle: When using the probe 4 device, first place the contact frame 3 against the wall surface, so that the probe 4 is aligned with the mortar. Then, hold the sleeve 535 on the rocker arm 534 and rotate the rocker arm 534. The rocker arm 534 drives the worm gear 532, which in turn drives the worm wheel 531 to rotate on the support seat 1. Under the limiting of the sliding block 542 and the connecting rod 543, the support block 51 and the threaded rod 52 maintain stable sliding. The worm wheel 531 drives the threaded rod 52 to move, which in turn drives the support block 51. The support block 51 drives the connecting seat 61, and the probe 4 on the connecting seat 61 is inserted into the mortar layer. During the movement of the probe 4... In the process, the pressure on probe 4 is transmitted to mechanical pressure gauge 7. The value on mechanical pressure gauge 7 is used to determine the strength of the masonry mortar. When the length of probe 4 does not match the depth of the masonry mortar to be tested, the fixing bolt 64 is directly rotated to disengage from the locking block 62. Then, the locking block 62 on probe 4 is slid out of the locking groove 63 on the connecting seat 61. The corresponding probe 4 and locking block 62 are then replaced. The locking block 62 on the new probe 4 is then inserted into the locking groove 63 on the connecting seat 61. Finally, the fixing bolt 64 is tightened again so that it abuts against the locking block 62, thus completing the replacement of probe 4.
