Description

Technical Field

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

[0002] In the field of construction engineering, the quality of concrete is directly related to the safety and durability of the entire building structure. The performance indicators of concrete, such as strength and density, need to be determined through precise testing. Therefore, concrete testing equipment plays a crucial role in construction and quality monitoring of building projects.

[0003] Traditional concrete testing equipment is exposed to the outside environment when performing extrusion testing on concrete. When the pressure plate applies pressure to the concrete, cracking may occur due to the unevenness of the internal structure of the concrete. The concrete fragments produced by the cracking can easily fly out and cause injury to the surrounding staff, resulting in relatively low safety.

[0004] Therefore, a concrete testing device for building engineering is provided to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete testing device for building engineering, in order to solve the problem mentioned in the background art that the existing technology exposes the concrete to the outside world when it is subjected to extrusion testing. When the pressure plate applies pressure to the concrete, cracking may occur due to the unevenness of the internal structure of the concrete, which may cause injury to the workers.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a concrete testing device for building engineering, comprising a base, several sets of guide slide rods fixedly installed on the upper surface of the base, a top plate fixedly installed at one end of each guide slide rod, a testing mechanism installed on the outer surface of the top plate, a placement seat fixedly installed on the upper surface of the base, and a protective mechanism provided on the lower surface of the testing mechanism. The protective mechanism includes a protective shell, rectangular grooves, and a movable shell. Two sets of rectangular grooves are opened on both sides of the protective shell, and the movable shell can extend and retract along the protective shell.

[0007] Furthermore, the protective mechanism also includes a connecting plate and a mounting plate. Two sets of connecting plates are fixedly installed on both sides of the movable shell. The connecting plates are slidably connected to the rectangular groove. Two sets of mounting plates are fixedly installed on both sides of the protective shell. The mounting plates are positioned above the rectangular groove.

[0008] Furthermore, the protective mechanism also includes a fixing cylinder and a spring. The lower surface of the mounting plate is fixedly equipped with a fixing cylinder, and the inner top of the fixing cylinder is fixedly equipped with a spring.

[0009] Furthermore, the protective mechanism also includes a limiting rod, which is slidably connected inside the fixed cylinder. The upper surface of the limiting rod is connected to one end of the spring, and one end of the limiting rod extends to the outer surface of the fixed cylinder and is connected to the upper surface of the connecting plate.

[0010] Furthermore, the testing mechanism includes a cylinder, a movable plate, an extension rod, and a pressure plate. The cylinder is fixedly installed on the upper surface of the top plate, and the movable plate is fixedly installed on the output end of the cylinder. The movable plate and the guide slide rod are slidably connected. The extension rod is fixedly installed on the lower surface of the movable plate, and the pressure plate is fixedly installed on the lower surface of the extension rod.

[0011] Furthermore, the protective shell is fixedly installed on the lower surface of the movable plate, and the extension rod and pressure plate are located in the middle of the interior of the protective shell.

[0012] This utility model has the following beneficial effects: (1) During the downward movement of the movable plate of this utility model, the protective shell is fixedly installed on the lower surface of the movable plate, so it also moves downward synchronously. The movable shell is slidably connected inside the protective shell. The connecting plates on both sides of the movable shell slide in the rectangular grooves on both sides of the protective shell. When the movable plate drives the pressure plate to squeeze the concrete for testing, the movable shell will first abut against the outer surface of the placement seat. At this time, the limiting rod inside the fixed cylinder fixedly installed on the lower surface of the mounting plate will slide inside the fixed cylinder. Since the upper surface of the limiting rod is connected to one end of the spring and the other end of the spring is fixed to the inner top of the fixed cylinder, the spring will be compressed. This causes the movable shell to contract into the interior of the protective shell. At the same time, the pressure plate continues to move downward until it contacts the concrete and squeezes it for testing. The protective shell and the movable shell wrap the pressure plate and the concrete to prevent the cracked concrete from injuring the staff. Without affecting the normal operation of the testing mechanism, the protective function is effectively realized and the safety performance of the equipment is improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 4 As shown, this utility model is a concrete testing equipment for building engineering testing, including a base 1, a number of guide slide rods 2 are fixedly installed on the upper surface of the base 1, a top plate 3 is fixedly installed at one end of the guide slide rods 2, a testing mechanism is installed on the outer surface of the top plate 3, a placement seat 5 is fixedly installed on the upper surface of the base 1, and a protective mechanism 9 is provided on the lower surface of the testing mechanism. The protective mechanism 9 includes a protective shell 901, a rectangular groove 902, and a movable shell 903. Two sets of rectangular grooves 902 are provided on both sides of the protective shell 901, and the movable shell 903 can extend and retract along the protective shell 901. The protective mechanism 9 also includes a connecting plate 904 and a mounting plate 905. Two sets of connecting plates 904 are fixedly installed on both sides of the movable shell 903. The connecting plates 904 and the rectangular groove 902 are slidably connected. Two sets of mounting plates 905 are fixedly installed on both sides of the protective shell 901. The mounting plates 905 are located above the rectangular groove 902. The protective mechanism 9 also includes a fixed cylinder 906 and a spring 907. The fixed cylinder 906 is fixedly installed on the lower surface of the mounting plate 905, and the spring 907 is fixedly installed on the inner top of the fixed cylinder 906. The protective mechanism 9 also includes a limiting rod 908. The limiting rod 908 is slidably connected inside the fixed cylinder 906. The upper surface of the limiting rod 908 is connected to one end of the spring 907. One end of the limiting rod 908 extends to the outer surface of the fixed cylinder 906 and is connected to the upper surface of the connecting plate 904. The testing mechanism includes a cylinder 4, a moving plate 6, an extension rod 7, and a pressure plate 8. The cylinder 4 is fixedly installed on the upper surface of the top plate 3. The moving plate 6 is fixedly installed on the output end of the cylinder 4. The moving plate 6 and the guide slide rod 2 are slidably connected. The extension rod 7 is fixedly installed on the lower surface of the moving plate 6. The pressure plate 8 is fixedly installed on the lower surface of the extension rod 7. The protective shell 901 is fixedly installed on the lower surface of the movable plate 6, and the extension rod 7 and the pressure plate 8 are located in the middle of the interior of the protective shell 901; As the movable plate 6 moves downward, the protective shell 901, fixedly installed on the lower surface of the movable plate 6, also moves downward synchronously. A movable shell 903 is slidably connected inside the protective shell 901. Connecting plates 904 on both sides of the movable shell 903 slide within rectangular grooves 902 on both sides of the protective shell 901. When the movable plate 6 drives the pressure plate 8 to squeeze the concrete for testing, the movable shell 903 will first abut against the outer surface of the placement seat 5. At this time, the limiting rod 908 inside the fixed cylinder 906, fixedly installed on the lower surface of the mounting plate 905, will slide within the fixed cylinder 906. Due to the limiting... The upper surface of the position rod 908 is connected to one end of the spring 907, and the other end of the spring 907 is fixed to the inner top of the fixed cylinder 906. Therefore, the spring 907 will be compressed, which causes the movable shell 903 to retract into the protective shell 901. At the same time, the pressure plate 8 continues to move downward until it contacts the concrete and performs a compression test. The protective shell 901 and the movable shell 903 enclose the pressure plate 8 and the concrete, preventing the collapsing concrete from injuring the staff. Without affecting the normal operation of the testing mechanism, the protective function is effectively realized and the safety performance of the equipment is improved.

[0018] First, place the concrete to be tested inside the placement seat 5. The cylinder 4 in the testing mechanism is activated. The output end of the cylinder 4 pushes the moving plate 6 to move downward along the guide slide rod 2. Because the lower surface of the moving plate 6 is fixed with the extension rod 7 and the lower surface of the extension rod 7 is fixed with the pressure plate 8, the pressure plate 8 will move downward along with the moving plate 6. As the movable plate 6 moves downward, the protective shell 901, fixedly installed on the lower surface of the movable plate 6, also moves downward synchronously. A movable shell 903 is slidably connected inside the protective shell 901. Connecting plates 904 on both sides of the movable shell 903 slide within the rectangular grooves 902 on both sides of the protective shell 901. When the movable plate 6 drives the pressure plate 8 to squeeze the concrete for testing, the movable shell 903 will first abut against the outer surface of the placement seat 5. At this time, the limiting rod 908 inside the fixed cylinder 906, fixedly installed on the lower surface of the mounting plate 905, will slide within the fixed cylinder 906. Because the upper surface of the limiting rod 908 is connected to the spring 907... One end of the spring 907 is connected to the other end of the fixed cylinder 906, so the spring 907 will be compressed. This causes the movable shell 903 to retract into the protective shell 901. At the same time, the pressure plate 8 continues to move downward until it contacts the concrete and squeezes it for testing. The protective shell 901 and the movable shell 903 enclose the pressure plate 8 and the concrete to prevent the collapsing concrete from injuring the staff. Without affecting the normal operation of the testing mechanism, the protective function is effectively realized and the safety performance of the equipment is improved. When the testing mechanism is reset, the protective mechanism 9 is also reset by the spring 907.
