Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a concrete testing device for construction. Background Technology

[0002] Concrete structures, with their high strength, durability, and construction flexibility, have become a core material in the construction industry. Prefabricated concrete structures, in particular, through factory prefabrication and on-site assembly, significantly improve construction efficiency and quality, reduce labor requirements and environmental pollution, and align with green building principles. However, their development still faces challenges such as the maturity of construction techniques and the design of connection nodes, requiring continuous innovation to address.

[0003] Concrete testing, especially hardness testing, is crucial for ensuring structural safety. Common methods include rebound hammer testing, ultrasonic testing, penetration testing, pull-out testing, and core drilling. Rebound hammer testing is quick and simple, but its accuracy is affected by surface condition; ultrasonic testing assesses internal quality and is suitable for defect detection; pull-out testing and core drilling provide accurate data, but are complex and destructive. Maturity methods estimate strength by monitoring setting temperature, enabling continuous monitoring and early warning. When selecting a testing method, it is essential to comprehensively consider the actual situation to ensure structural quality and long-term safety.

[0004] Patent document CN216349950U discloses a concrete strength testing device for construction, belonging to the technical field of concrete testing equipment. The device includes a base, with a frame fixedly mounted on the top of the base. The frame is in an inverted U-shape. A platform is fixedly connected to the top of the frame, and a first hydraulic cylinder is fixedly mounted on the top of the platform. A main shaft is mounted at the output end of the first hydraulic cylinder. The bottom end of the main shaft passes through the platform and the top of the frame and inserts into the inside of the frame. A testing head is fixedly connected to the bottom end of the main shaft. This invention solves the problems of existing concrete strength testing devices, such as concrete test block breakage easily causing platform contamination and personnel injury.

[0005] As in the prior art of the aforementioned patent, although the device can limit and fix the concrete in the middle through the limiting plates on both sides during the concrete testing process, concrete fragments will still fly out from the gap between the two limiting plates, thus posing a threat to the testing personnel. In addition, the broken concrete fragments and small debris remain on the surface of the testing table, which are difficult to clean. If they are not cleaned in time, they will affect the subsequent testing. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A concrete testing device for construction includes two support plates 1, a conveying assembly and a scraping assembly disposed between the two support plates 1, a frame 5 fixedly mounted on the top of the two support plates 1, a cylinder 6 fixedly mounted on the top of the frame 5, a pressure block 7 being drivenly connected to the output end of the cylinder 6, fixing plates 10 fixedly mounted on both sides of the pressure block 7, an elastic telescopic assembly 8 disposed at the bottom end of the fixing plate 10, a protective cover 9 disposed at the bottom end of the elastic telescopic assembly 8, a through groove 11 formed on the protective cover 9, the through groove 11 being slidably connected to the pressure block 7, and a testing head 12 disposed at the bottom end of the pressure block 7; the concrete sample to be tested is placed on the surface of the conveyor belt 4. The cylinder 6 drives the pressure block 7 to move downwards. During the downward movement of the pressure block 7, the protective cover 9 is first placed on the surface of the concrete sample below. Then the cylinder 6 continues to press the pressure block 7 downwards. After the detection head 12 at the bottom of the pressure block 7 contacts the concrete sample, the cylinder 6 continues to press the sample downwards. The detection head 12 detects the hardness of the sample. The detection head 12 is existing technology and will not be described in detail. When the sample breaks, the protective cover 9 can prevent the fragments of the broken concrete sample from causing damage to the outside world and control the fragments of the concrete sample inside the protective cover 9. Subsequently, the fragments can be recycled and transported by the conveying component, and the surface of the conveying component can be cleaned by the scraping component.

[0025] As a preferred technical solution of this embodiment, the elastic telescopic component 8 includes a fixed cylinder 801 fixedly installed on the top of the protective cover 9. A sliding rod 803 is slidably installed inside the fixed cylinder 801. The top end of the sliding rod 803 is fixedly connected to the fixed plate 10. A spring 802 is provided inside the fixed cylinder 801. The two ends of the spring 802 are fixedly connected to the sliding rod 803 and the bottom wall inside the fixed cylinder 801, respectively. When the sliding rod 803 slides downward, it can compress the spring 802, and the protective cover 9 can tightly cover the concrete sample.

[0026] As a preferred embodiment, the conveying assembly includes a transmission roller 3 rotatably mounted between two support plates 1, a conveyor belt 4 drivingly connected between the two transmission rollers 3, and a support block 13 fixedly mounted between the two support plates 1. The top end of the support block 13 is tightly attached to the bottom end of the upper conveyor belt 4. A motor 2 is fixedly mounted on the side wall of one of the support plates 1, and the output end of the motor 2 is drivingly connected to one of the transmission rollers 3. During testing, the motor 2 does not work. When the test is completed and the sample on the surface of the conveyor belt 4 needs to be processed, the motor 2 drives the transmission roller 3 to rotate, thereby driving the conveyor belt 4 to convey the sample. The support block 13 ensures that the upper conveyor belt 4 will not collapse downwards when testing concrete samples, so that the conveyor belt 4 achieves the same hardness and effect as the testing platform.

[0027] As a preferred technical solution in this embodiment, the slag scraping assembly includes a rotating roller 14 rotatably mounted between two support plates 1. Multiple scrapers 16 are fixedly mounted on the surface of the rotating roller 14. A transmission belt 15 is connected between the rotating roller 14 and one of the transmission rollers 3. The rotation of the transmission roller 3, under the action of the transmission belt 15, can drive the rotation of the rotating roller 14, thereby enabling the multiple scrapers 16 to scrape off the debris on the surface of the conveyor belt 4, ensuring that the surface of the conveyor belt 4 is smooth and avoiding any impact on subsequent inspection.

[0028] As a preferred technical solution of this embodiment, a slag discharge trough 17 is provided between the support plates 1, and the slag discharge trough 17 is located below the rotating roller 14; the slag discharge trough 17 can collect and recycle the debris scraped off by multiple scrapers 16.

[0029] As a preferred technical solution in this embodiment, the surface of the conveyor belt 4 is provided with a wear-resistant layer 401; the wear-resistant layer 401 increases the wear resistance of the surface of the conveyor belt 4 and increases the service life of the conveyor belt 4.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
