Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a concrete strength tester for building engineering. Background Technology

[0002] Concrete strength testing is one of the important quality inspection standards for construction projects before construction. Testing can effectively improve the quality of building construction, which can not only speed up the construction progress but also avoid many safety hazards. Therefore, it is necessary to use a concrete strength tester to test the strength of concrete.

[0003] Chinese Patent Application No. 202320560221.9 discloses a concrete strength tester for testing the quality of building engineering, including an operating table. A rubber anti-slip pad is provided on the top left side of the operating table, and a side panel is provided on the top left side of the operating table, with the side panel located to the left of the rubber anti-slip pad. A top plate is provided on the top right side of the side panel, and a threaded hole is vertically provided through the center of the top plate. A matching external threaded rod is movably connected to the top plate through the threaded hole.

[0004] The above-mentioned scheme features telescopic rods on both the front and rear ends of the right side of the extrusion plate, allowing for simultaneous extrusion of the concrete sample from both sides. Compared to traditional methods, this results in more even force distribution and less deformation of the extrusion plate. Furthermore, the extrusion plate and the fixing plate are connected by threaded holes and fixing bolts, enabling easy replacement or correction even if the extrusion plate deforms after prolonged use, thus preventing interference with test results. However, the above scheme has limitations in actual replacement. The threaded hole connection to the fixing plate requires a screwdriver for continuous tightening, and the threaded hole is prone to rusting after long-term use, making the bolt difficult to tighten and affecting the efficiency of extrusion plate replacement. Therefore, we provide a concrete strength testing instrument for building engineering to address these issues. Utility Model Content

The output end of the electric push rod is fixedly connected to the right side of the installation groove, and a limiting component is provided above the test platform.

[0007] Furthermore, both of the limiting mechanisms include a tongue-shaped plate, the outer surface of which is slidably connected to the inner wall of the mounting groove and the mating insert plate, respectively.

[0008] Furthermore, each of the two tongue-shaped plates has a pull rod fixedly connected to its opposite side, and the outer surfaces of the two pull rods are slidably connected to the inner wall of the mounting groove.

[0009] Furthermore, a return spring is wound around the outer surface of the pull rod, and the front and rear ends of the return spring are fixedly connected to the outer surface of the mounting groove and the outer surface of the pull rod, respectively.

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] This embodiment provides a concrete strength tester for building construction. The device is used to test the strength of concrete during construction. Through the cooperation between the installation groove 3 and the limiting mechanism 5, the extrusion plate 6 can be quickly replaced, avoiding the need to repeatedly tighten the bolts when replacing the extrusion plate 6, thereby saving workers time and effort when replacing the extrusion plate 6.

[0019] See Figures 1-4 A concrete strength tester for building construction includes a test platform 1. The inner wall of the test platform 1 is slidably connected to two symmetrical sliding reinforcing plates 2. The test platform 1 has a slot inside that is adapted to the two sliding reinforcing plates 2. The two sliding reinforcing plates 2 can provide reinforcement and support for the mounting slot 3.

[0020] The left side of each of the two sliding reinforcing plates 2 is fixedly connected to an installation groove 3. The inner wall of the installation groove 3 is slidably connected to a mating plate 4. The right side edge of the mating plate 4 is arc-shaped, which facilitates the pushing of the tongue plate 502 when the mating plate 4 is pushed into the installation groove 3. The installation groove 3 is provided with two symmetrical limiting mechanisms 5, each of which includes a tongue plate 502. The outer surface of the tongue plate 502 is slidably connected to the inner wall of the installation groove 3 and the mating plate 4, respectively. The mating plate 4 is provided with two symmetrical slots, which facilitates the limiting of the mating plate 4 by the tongue plate 502.

[0021] Pull rods 501 are fixedly connected to the two tongue plates 502 on their opposite sides. The outer surfaces of the two pull rods 501 are slidably connected to the inner wall of the mounting groove 3. A return spring 503 is wound around the outer surface of the pull rod 501. The front and rear ends of the return spring 503 are fixedly connected to the outer surface of the mounting groove 3 and the outer surface of the pull rod 501, respectively.

[0022] By using the elastic force of the reset spring 503, the two tongue plates 502 can be reset, thus limiting the two tongue plates 502 to the slot inside the mating insert plate 4.

[0023] An extrusion plate 6 is fixedly connected to the left side of the mounting slot 3. The right side of the extrusion plate 6 is in contact with the left side of the mounting slot 3. A support frame 7 is fixedly connected to the upper surface of the test bench 1. An electric push rod 8 is provided inside the support frame 7. The output end of the electric push rod 8 is fixedly connected to the right side of the mounting slot 3.

[0024] By activating the electric push rod 8, the mounting groove 3 and the extrusion plate 6 can be moved, thereby enabling the extrusion plate 6 to test the strength of the building concrete. A limiting component 9 is provided above the test bench 1. A side baffle 10 is fixedly connected to the upper surface of the test bench 1. A support plate 11 is fixedly connected to the upper surface of the side baffle 10. A rubber pad 12 is provided on the upper surface of the test bench 1.

[0025] By using the set limit component 9, displacement of the building concrete can be avoided, which would affect the detection of the building concrete and thus avoid affecting the construction of the building project.

[0026] The limiting component 9 includes a threaded rod 902, the outer surface of which is threadedly connected to the inner wall of the support plate 11, and a rotating disk 901 is fixedly connected to the upper surface of the threaded rod 902.

[0027] By using the rotating disk 901, the threaded rod 902 can be rotated easily, which makes it convenient for workers to inspect it.

[0028] The bottom surface of the threaded rod 902 is rotatably connected to a limiting pressure plate 903, and the upper surface of the limiting pressure plate 903 is fixedly connected to two limiting slide rods 904. The outer surfaces of the two limiting slide rods 904 are slidably connected to the inner wall of the support plate 11 respectively.

[0029] By setting two limiting slide bars 904, the up and down movement of the limiting pressure plate 903 can be limited, so as to prevent the limiting pressure plate 903 from becoming skewed.

[0030] Working principle: When using this device to test the strength of building concrete, the building concrete is first placed on the upper surface of the rubber pad 12 along the right side of the side baffle 10. Then, by rotating the rotating disk 901, the threaded rod 902 is rotated, which in turn moves the limiting pressure plate 903 downward, thereby limiting and clamping the building concrete. By activating the electric push rod 8, the mounting groove 3 and the extrusion plate 6 are moved, allowing the extrusion plate 6 to test the strength of the building concrete. By pulling the two levers 501 in a direction away from each other, the tongue plates 502 can be moved in the same direction, allowing the mating insert plate 4 and the pressing plate 6 to be pulled out of the mounting groove 3. Then, by pushing the new mating insert plate 4 and the pressing plate 6 back into the mounting groove 3, the mating insert plate 4 can push the two tongue plates 502 in a direction away from each other until the mating insert plate 4 contacts the inner wall of the right side of the mounting groove 3. Under the elastic force of the two return springs 503, the two tongue plates 502 can be reset, thus limiting the mating insert plate 4. This allows for convenient and quick replacement of the pressing plate 6.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
