Technical Field
[0001] This utility model relates to the field of building construction quality testing technology, and in particular to a steel reinforcement strength testing device for building construction quality supervision. Background Technology
[0002] The steel reinforcement strength testing device used for construction quality supervision uses a cylinder pressing method as its core. By precisely controlling the cylinder pressure, it simulates the actual stress condition of the steel reinforcement to test its strength. The device is equipped with a high-precision pressure sensor that can monitor pressure data in real time to ensure accurate and reliable test results. It also has an intelligent control system that can preset test parameters and control the loading rate. The user interface is simple and easy for staff to use. Its stable structure can adapt to complex construction site environments. This device is of great significance for ensuring the quality of steel reinforcement in construction, effectively avoiding safety hazards caused by insufficient steel reinforcement strength, and helping to create high-quality construction projects.
[0003] Existing technologies include, for example, the utility model with publication number CN215812075U. This utility model relates to the field of testing technology, specifically a high-strength rebar strength testing device. It includes a base, a worktable at the upper end of the base, and a fixed clamp at the upper end of the worktable, which is movably connected to the worktable. A fixed housing is located on one side of the fixed clamp, with a driving device at the upper end of the fixed housing and a telescopic device at the upper end of the fixed housing.

[0004] However, during the testing process, when the steel bar breaks, it produces a large number of fragments. The flying steel bar fragments may damage the surrounding instruments and equipment, causing testing interruptions, inaccurate data, and increased testing costs and time. If the fragments cause other objects to tip over or collide, it may cause secondary accidents and expand the scope of harm. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the generation of numerous fragments when reinforcing bars break during the testing process. These flying fragments may damage surrounding instruments and equipment, leading to testing interruptions, inaccurate data, increased testing costs and time, and potential secondary accidents and expanded hazards if the fragments cause other objects to tip over or collide. Therefore, this invention proposes a reinforcing bar strength testing device for construction quality supervision.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a steel reinforcement strength testing device for construction quality supervision, comprising a base and a protective device. A pressure testing instrument is fixedly connected to the upper surface of the base, and a clamp is provided on the inner wall of the base. The protective device is disposed on the surface of the base and includes a retaining ring, which is fixedly connected to the base. A circular frame is rotatably connected to the inner wall of the retaining ring, and a rotating rod is rotatably connected to the inner wall of the circular frame. A tensile-resistant fabric is sleeved on the surface of the rotating rod, and a turbine coil spring is sleeved on the inner wall of the circular frame. One end of the turbine coil spring... The end of the coil spring is engaged with the rotating rod, and the end of the coil spring away from the rotating rod is installed with the retaining ring. By setting a protective device, the tensile cloth is pulled down during testing and a protective barrier is formed by hooks and buckles. This can directly block the fragments that fly out when the steel bar breaks. As a special protective material, the tensile cloth has high strength and toughness, which can effectively prevent fragments from causing harm to operators and the surrounding environment, greatly reducing safety hazards. When fragments hit the tensile cloth, the material properties of the tensile cloth enable it to absorb some energy, reducing the impact force generated at the moment of impact, further ensuring personnel safety and equipment integrity.
[0007] Preferably, the lower surface of the tensile fabric is fixedly connected to a hook, and the base is fixedly connected to a buckle on the side near the hook. By setting the tensile fabric, the tensile fabric acts as a physical barrier, which can directly intercept the flying fragments when the steel bar breaks, preventing them from scattering everywhere and avoiding damage to operators, surrounding equipment and the environment. It is the primary line of defense for ensuring safety.
[0008] Preferably, the buckle is engaged with the hook, and the buckle is located on the lower surface of the hook. By setting the hook, during testing, the anti-tensile fabric can be quickly and firmly fixed in the required position by engaging the hook with the buckle, forming an effective protective barrier. This connection method is simple to operate, requires no complicated tools or professional skills, and can complete the construction of the protective device in a short time, improving the efficiency of testing preparation.
[0009] Preferably, there are two hooks, which are arranged in a mirror-symmetrical manner.
[0010] Preferably, the lower surface of the clamp is provided with a replacement device, which includes a cylinder fixedly connected to the base. A rod is fixedly connected to the lower surface of the clamp and inserted into the cylinder. A slot is formed on the surface of the cylinder. An assembly block is fixedly connected to one side of the rod. By setting the replacement device, the clamp can be replaced when steel bars of various diameters are used in construction. This ensures that the device can firmly clamp steel bars of different diameters, meet various testing needs, avoid the need to purchase multiple special equipment due to different steel bar specifications, and improve the versatility and economy of the equipment.
[0011] Preferably, the assembly block engages with the slot, and the surface of the assembly block has an insertion hole.
[0012] Preferably, one end of the cylinder is threaded with a threaded rod, which is inserted into a hole on the surface of the assembly block. By setting the threaded rod, after selecting a clamp that matches the diameter of the reinforcing bar, rotating the threaded rod causes it to interact with the assembly block, thus firmly fixing the clamp onto the cylinder. The threaded structure of the threaded rod closely matches the internal thread of the assembly block, generating sufficient friction and fastening force to ensure that the clamp will not loosen due to external forces such as tension or vibration during the reinforcing bar strength testing process, thereby ensuring the smooth progress of the test.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] In this invention, by setting up a protective device and a replacement device, during testing, the anti-tensile cloth is pulled down, and the hook and buckle are engaged. When the steel bar breaks, the fragments are blocked by the anti-tensile cloth, which buffers the impact force of the fragments and reduces the occurrence of safety hazards. After the test is completed, the hook is pulled to disengage from the buckle, and the worm gear spring is released from its restraint, causing the rotating rod to quickly rewind the anti-tensile cloth. When the diameter of the steel bar does not match the size of the clamp, the threaded rod is rotated to disengage from the assembly block, and the clamp can be pulled out. The appropriate clamp is then inserted into the cylinder and tightened by the threaded rod, and it can be used. By setting up this invention, the anti-tensile cloth is pulled down during testing, and a protective barrier is formed by the hook and buckle, which can directly block the fragments that fly out when the steel bar breaks. As a special protective material, the anti-tensile cloth has high strength and toughness, which can effectively prevent fragments from causing injury to operators and the surrounding environment, greatly reducing safety hazards. When fragments hit the anti-tensile cloth, the material properties of the anti-tensile cloth allow it to absorb some energy, reducing the impact force generated at the moment of impact, further ensuring personnel safety and equipment integrity.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a steel bar strength testing device for supervising the quality of building construction, including a base 1 and a protective device 4. A pressure testing instrument 2 is fixedly connected to the upper surface of the base 1, a clamp 3 is provided on the inner wall of the base 1, and the protective device 4 is provided on the surface of the base 1.
[0022] The specific setup and function of its protective device 4 and replacement device 5 will be explained below.
[0023] In this implementation scheme: the protective device 4 includes a retaining ring 45, which is fixedly connected to the base 1. A circular frame 46 is rotatably connected to the inner wall of the retaining ring 45, and a rotating rod 44 is rotatably connected to the inner wall of the circular frame 46. An anti-tensile cloth 41 is sleeved on the surface of the rotating rod 44, and a spiral spring 47 is sleeved on the inner wall of the circular frame 46. One end of the spiral spring 47 is engaged with the rotating rod 44, and the end of the spiral spring 47 away from the rotating rod 44 is installed with the retaining ring 45. By setting up the protective device 4, the anti-tensile cloth 41 is pulled down during testing and engaged with the buckle 43 through the hook 42 to form a protective barrier, which can directly block the fragments that fly out when the steel bar breaks. As a special protective material, the anti-tensile cloth 41 has high strength and toughness, which can effectively prevent fragments from causing harm to operators and the surrounding environment, greatly reducing safety hazards. When fragments hit the anti-tensile cloth 41, the material properties of the anti-tensile cloth 41 enable it to absorb some energy, reduce the impact force generated at the moment of fragment impact, and further ensure personnel safety and equipment integrity.
[0024] Specifically, a hook 42 is fixedly connected to the lower surface of the tensile fabric 41, and a buckle 43 is fixedly connected to the side of the base 1 near the hook 42. By setting the tensile fabric 41, the tensile fabric 41 acts as a physical barrier. When the steel bar breaks, it can directly intercept the flying fragments and prevent them from scattering everywhere. This avoids damage to operators, surrounding equipment and the environment caused by the fragments, and is the primary line of defense for ensuring safety.
[0025] Specifically, the buckle 43 is engaged with the hook 42. The buckle 43 is located on the lower surface of the hook 42. By setting the hook 42, during testing, the anti-tensile cloth 41 can be quickly and firmly fixed in the required position by engaging the hook 42 with the buckle 43, forming an effective protective barrier. This connection method is simple to operate, requires no complicated tools or professional skills, and can complete the construction of the protective device 4 in a short time, improving the efficiency of testing preparation.
[0026] Specifically, there are two hooks 42, which are arranged in a mirror-symmetrical manner.
[0027] Specifically, a replacement device 5 is provided on the lower surface of the fixture 3. The replacement device 5 includes a cylinder 51, which is fixedly connected to the base 1. A rod 53 is fixedly connected to the lower surface of the fixture 3. The rod 53 is inserted into the cylinder 51. A slot is provided on the surface of the cylinder 51. An assembly block 52 is fixedly connected to one side of the rod 53.
[0028] In this embodiment: by setting up the replacement device 5, the diameter of the steel bars in the construction is diverse. The replacement device 5 can replace the clamp 3 to ensure that the device can firmly clamp steel bars of different diameters, meet various testing needs, avoid the need to purchase a variety of special equipment due to different steel bar specifications, and improve the versatility and economy of the equipment.
[0029] Specifically, the assembly block 52 engages with the slot, and the surface of the assembly block 52 has insertion holes.
[0030] Specifically, one end of the cylinder 51 is threadedly connected to a threaded rod 54, which is inserted into a hole on the surface of the assembly block 52.
[0031] In this embodiment: by setting the threaded rod 54, after selecting the clamp 3 that matches the diameter of the reinforcing bar, the threaded rod 54 is rotated to interact with the assembly block 52, and the clamp 3 is firmly fixed on the cylinder 51. The threaded structure of the threaded rod 54 is tightly engaged with the internal thread of the assembly block 52, which can generate sufficient friction and fastening force to ensure that the clamp 3 will not loosen due to external forces such as tension and vibration during the reinforcing bar strength test, thereby ensuring the smooth progress of the test.
[0032] Working principle: By setting up protective device 4 and replacement device 5, during testing, pulling down the tensile cloth 41 engages the hook 42 with the buckle 43. When the rebar breaks, the fragments are blocked and buffered by the tensile cloth 41, reducing the occurrence of safety hazards. After testing, pulling the hook 42 disengages from the buckle 43, and the turbine coil spring 47 releases its elasticity, driving the rotating rod 44 to quickly rewind the tensile cloth 41. When the diameter of the rebar does not match the clamp 3, rotating the threaded rod 54 disengages from the assembly block 52, allowing the clamp 3 to be pulled out. The appropriate clamp 3 is then inserted into the cylinder 51, and the screw... Once the reinforcing bar 54 is tightened, it can be used. By setting up this utility model, during testing, the tensile cloth 41 is pulled down and connected to the buckle 43 through the hook 42 to form a protective barrier, which can directly block the fragments that fly out when the steel bar breaks. As a special protective material, the tensile cloth 41 has high strength and toughness, which can effectively prevent fragments from causing harm to operators and the surrounding environment, greatly reducing safety hazards. When fragments hit the tensile cloth 41, the material properties of the tensile cloth 41 enable it to absorb some energy, reduce the impact force generated at the moment of impact, and further ensure personnel safety and equipment integrity.
