Description

Technical Field

[0001] This utility model relates to the field of concrete molding testing equipment, and more specifically, to a novel bubble testing device for concrete molding. Background Technology

[0002] Concrete is an artificial stone material made by mixing cement, sand, stone and other aggregates with water in a certain proportion, and then hardening it through mixing, pouring and curing. Its hardening process depends on the cement hydration reaction to form a hard whole. It has the characteristics of high strength, good durability and strong plasticity. It is widely used in construction, bridges and roads. The proportion can be adjusted according to needs to make products of different strength grades. Adding admixtures can improve performance. For example, water-reducing agents improve fluidity and early strength agents accelerate hardening. During the curing stage, it is necessary to keep it moist and heat-insulated to ensure normal strength development. It is a core material of modern civil engineering.

[0003] Air bubbles on the surface of concrete not only affect its appearance but also its durability and structural safety. The causes of surface bubbles in concrete are complex, including factors such as river sand gradation, water-reducing agents, overall concrete slump, air content, plastic viscosity, release agent selection, concrete thickness, and vibration. Many scholars have conducted related research, and these studies on the influence of one or more factors on concrete bubbles have shown positive research value from laboratory results. However, in practical engineering operations, it is often necessary to reverse-engineer the causes based on the on-site construction results to find improvement measures. Eliminating all possible causes of surface bubbles is not only labor-intensive but also impractical from a project timeline perspective. Therefore, we propose a novel bubble testing device for concrete molding. Utility Model Content

[0020] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A novel bubble testing device for concrete molding includes a base plate 1. Two first baffles 2 and two second baffles 3 are fixedly installed on the upper surface of the base plate 1. The front and rear surfaces of the two second baffles 3 are fixedly connected with mating protrusions 4. The adjacent surfaces of the two first baffles 2 are provided with mating grooves 5, which are adapted to the mating protrusions 4.

The upper surface of the limiting blocks 8 is provided with fixing grooves 9, which are adapted to the fixing rods 7. An auxiliary pressing component is provided on the base plate 1.

[0021] Furthermore, such as Figure 2 As shown, the auxiliary pressing assembly includes two guide plates 10, both of which are fixedly connected to the upper surface of the base plate 1. The two guide plates 10 are located on the left and right sides of the limiting block 8, respectively. A threaded groove 11 is formed on the upper surface of the limiting block 8. A threaded rod 12 is threaded inside the threaded groove 11. The upper end of the threaded rod 12 extends out of the threaded groove 11. An annular rotating groove 13 is formed on the outer surface of the threaded rod 12. A control knob 14 is fixedly connected to the upper end of the threaded rod 12. The upper end of the control knob 14... The side surface is provided with a hexagonal groove 15, and a pressing plate 16 is provided on the threaded rod 12. The pressing plate 16 is rotatably sleeved inside the annular rotating groove 13. The left and right widths of the pressing plate 16 are adapted to the spacing between the two guide plates 10. The pressing plate 16 can be used in conjunction with the fixing rod 7 and the fixing groove 9 to ensure the stability after the mold is assembled. Moreover, the fixing method is more convenient and firm than the traditional binding. At the same time, the cooperation between the mating protrusion 4 and the mating groove 5 can increase the tightness between the first baffle 2 and the second baffle 3.

[0022] Example 2 The novel bubble testing equipment for concrete molding provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 4As shown, the system includes two L-shaped support plates 17, which are fixedly connected to the front surface of the first baffle 2. A scraper 18 is provided between the vertical plate of the two L-shaped support plates 17 and the first baffle 2. A sealing cover 19 is provided on the upper side of the first baffle 2 and the second baffle 3. A counterweight 20 is fixedly connected to the upper surface of the sealing cover 19, and a lifting handle 21 is fixedly connected to the upper surface of the counterweight 20. Four clamping plates 22 are fixedly connected to the lower surface of the sealing cover 19. The inner sides of the four clamping plates 22 are all set as inclined surfaces. The inner sides of the four clamping plates 22 contact the two first baffles 2 and the two second baffles 3 respectively. The L-shaped support plates 17 can be used to fix the scraper 18. At the same time, the optional sealing cover 19 can be used to avoid the concrete molding being affected by unsuitable surrounding environment. Furthermore, the clamping plates 22 can further increase the tightness of the combination of the first baffle 2 and the second baffle 3.

[0023] The usage process of the novel bubble testing equipment for concrete molding provided by this utility model is as follows: First, place the base plate 1 on the ground. Then, place the two first baffles 2 on the base plate 1, closing them so that the fixing rods 7 on the first baffles 2 are inserted into the fixing grooves 9. Next, place the two second baffles 3 between the two first baffles 2, aligning the mating protrusions 4 on the second baffles 3 with the mating grooves 5 on the first baffles 2. When inserted to the bottom, ensure that the fixing rods 7 on the second baffles 3 are also inserted into the fixing grooves 9. Then, take the threaded rod 12 and screw it into the threaded groove 11. As the threaded rod 12 rotates and gradually descends, it will drive the pressing plate 16 to descend synchronously. At this time, the guide plates 10 on both sides restrict the movement trajectory of the pressing plate 16. The pressing plate 16 presses down on multiple mounting plates 6, thereby ensuring the stability of the combination of the first baffles 2 and the second baffles 3. The prepared concrete is then mixed using a mixer. After mixing, it is first poured into the concrete in one go. After filling, three-point vibration is used to remove as many air bubbles as possible. Then, scraper 18 is used to scrape off the overflowing concrete and make the surface of the concrete slurry smooth. Then, according to the requirements, the sealing cover 19 is placed on the first baffle 2 and the second baffle 3, and the clamping plate 22 is tightly attached to the first baffle 2 and the second baffle 3. This equipment can be set up in multiple groups and combined with single variable experimental methods, such as simultaneously examining multiple variables such as vibration method, release agent type, manufactured sand ratio, sand ratio and water volume, to comprehensively analyze their influence on air bubbles on the concrete surface. This can more accurately simulate actual construction conditions, reveal the interaction between various factors, and thus provide more scientific and practical guidance for engineering practice.
