Description

Technical Field

[0001] This utility model belongs to the field of building engineering testing technology, specifically relating to a pressure-resistant clamp for building engineering testing. Background Technology

[0002] The compressive strength test of building test blocks refers to a testing method that applies axial pressure to standard cured test blocks of concrete, mortar, etc., using a pressure testing machine to determine their ultimate compressive strength, thereby evaluating the mechanical properties of building materials. During the test, the test block is placed between pressure plates and loaded at a constant rate until failure. The maximum load value is recorded and the compressive strength is calculated.

[0003] Chinese patent application 202420098672.X discloses a pressure-resistant clamp for building engineering testing.

This invention, through the moving limiting mechanism and a set of fixed limiting blocks, can limit cement mortar test blocks of different sizes, preventing the cement mortar test blocks from moving under pressure, thus avoiding inaccurate testing and improving accuracy. The angle adjustment component allows adjustment of the angle of the movable arm and the moving limiting blocks, enabling the limiting of cement mortar test blocks of different shapes, thus improving the clamp's practicality.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figure 1-4 This is an embodiment of the present invention, which provides a compressive strength clamp for building engineering testing, comprising:

[0029] The testing mechanism 100 includes a support plate 110, a fixing frame 120 fixedly installed on the top of the support plate 110, a testing component 130 for compressive strength testing disposed on the fixing frame 120, and a test block 140 disposed on the top of the support plate 110.

[0030] The surface treatment mechanism 200 includes a grinding component 210 for grinding the top of the test block 140 flat, and an adjustment component 220 for effectively grinding different test blocks 140.

[0031] The grinding component 210 and the adjusting component 220 work together to grind test blocks 140 of different heights, which solves the problem that the traditional testing device is affected by the insufficient flatness of the test block 140 surface, thus achieving the effect of grinding the test block 140 surface flat and improving the accuracy of the compressive strength test.

[0032] Specifically, the grinding component 210 includes a support frame 211 fixedly mounted on the top of the support plate 110, a slider 212 slidably mounted on the support frame 211, a protrusion 213 fixedly mounted on one side of the slider 212, a grinding motor 214 fixedly mounted on the top of the protrusion 213, a grinding disc 215 fixedly mounted on the output end of the grinding motor 214 and used for grinding the top of the test block 140, and a reciprocating motor 216 fixedly mounted on the surface of the support plate 110 and used for driving the slider 212 to move back and forth.

[0033] In this process, a reciprocating motor 216 drives a lead screw 217 to rotate. The lead screw 217 moves a threaded sleeve 218, causing the threaded sleeve 218 to move a slider 212 within a limiting groove 219. The slider 212 then moves a grinding disc 215 over the top of the test block 140. Under the action of a grinding motor 214, the grinding disc 215 rotates, grinding the top of the test block 140 as it passes over it. This grinds the top of the test block 140 flat, preventing insufficient flatness of the test block 140 from affecting the contact between the pressure plate 133 and the test block 140, which could lead to inaccurate pressure resistance testing.

[0034] Furthermore, the grinding component 210 also includes a lead screw 217 fixedly mounted on the output end of the reciprocating motor 216, and a threaded sleeve 218 fixedly mounted on the surface of the slider 212 and used in conjunction with the lead screw 217.

[0035] Preferably, the surface of the support frame 211 is provided with a limiting groove 219 that cooperates with the sliding block 212 to slide, and the surface of the sliding block 212 is fixedly installed with a baffle for limiting.

[0036] The limiting groove 219 is used to limit the sliding of the slider 212, ensuring the sliding stability of the slider 212.

[0037] Furthermore, the adjusting component 220 includes a threaded groove formed on the surface of the support plate 110, a threaded block 221 threadedly installed inside the threaded groove, and a rotating plate 222 fixedly installed at the bottom of the threaded block 221.

[0038] Several clamping blocks for limiting the test block 140 are fixedly installed on the top of the threaded block 221.

[0039] The rotating plate 222 facilitates the rotation of the threaded block 221, allowing the threaded block 221 to rotate inside the mounting groove. When the threaded block 221 rotates, it moves up and down, thereby adjusting the height of the top of the threaded block 221, which is convenient for grinding test blocks 140 of different heights.

[0040] The clamping block is used to limit the position of the test block 140 and improve the stability of the test block 140 during the compression test.

[0041] Specifically, the threaded block 221 has a positioning threaded sleeve 223 on its surface, which is engaged with the bottom of the support plate 110.

[0042] The positioning threaded sleeve 223 is used to limit the support frame 211, improve the installation stability of the support frame 211 in the threaded groove, and thus ensure that the height of the test block 140 remains unchanged, ensuring the grinding effect on the top of the test block 140.

[0043] Furthermore, the testing component 130 includes a hydraulic cylinder 131 fixedly installed on the top of the fixing frame 120, a connecting plate 132 fixedly installed on the output end of the hydraulic cylinder 131, a pressure plate 133 fixedly installed on the bottom of the connecting plate 132 for pressure testing of the test block 140, two positioning rods 134 fixedly installed on the top of the connecting plate 132, and a return spring 135 sleeved on the surface of the positioning rods 134.

[0044] The pressure plate 133 has a flexible pad at its bottom to compensate for minor unevenness at the top of the test block 140. The support plate 110 has two positioning holes on its surface that work with the positioning rod 134. The hydraulic cylinder 131 drives the connecting plate 132 to move downward. The connecting plate 132 drives the pressure plate 133 to move downward to perform a pressure test on the test block 140. After the test is completed, the hydraulic cylinder 131 is closed, and the connecting plate 132 and the pressure plate 133 are reset upward under the elastic force of the return spring 135.

[0045] In use, the reciprocating motor 216 drives the lead screw 217 to rotate, and the lead screw 217 drives the threaded sleeve 218 to move, so that the threaded sleeve 218 drives the slider 212 to slide inside the limiting groove 219. The slider 212 drives the grinding disc 215 to pass over the top of the test block 140. Under the action of the grinding motor 214, the grinding disc 215 is driven to rotate, so that the grinding disc 215 grinds the top of the test block 140 when it passes over it, and grinds the top of the test block 140 flat.

[0046] The rotating plate 222 facilitates the rotation of the threaded block 221, allowing the threaded block 221 to rotate inside the mounting groove. When the threaded block 221 rotates, it moves up and down, thereby adjusting the height of the top of the threaded block 221, which is convenient for grinding test blocks 140 of different heights.

[0047] In summary, the cooperation between the grinding component 210 and the adjusting component 220 can be used to grind test blocks 140 of different heights, solving the problem that the accuracy of traditional testing devices is affected by insufficient surface flatness of the test block 140, and achieving the effect of grinding the surface of the test block 140 to improve the accuracy of the compressive strength test.
