Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically, the utility model is a demoulding device for a concrete test block. Background Art

[0002] In the field of construction, concrete test blocks, with their unique status and importance, are an important basis for judging key properties of concrete, such as strength and durability. The production of concrete test blocks is essentially a process of pouring concrete into a specific mold and finally solidifying it into a shape. However, in this process, a problem that cannot be ignored often troubles construction workers - the concrete slurry on the upper edge of the mold.

[0003] Concrete slurry is formed when part of the cement paste floats to the concrete surface due to vibration, water seepage and other reasons during the concrete pouring process. This layer of slurry will adhere tightly to the mold during demoulding, making the demoulding process extremely difficult. This not only increases the labor intensity of the construction workers, but may also damage the test blocks due to improper operation, affecting the accuracy of the test results. It is even more difficult to quickly demould three concrete test blocks in one mold.

[0004] In order to solve this problem, various concrete test block demoulding auxiliary devices have emerged in the industry. For example, the "A concrete test block demoulding auxiliary device" disclosed in the Chinese utility model patent disclosure specification CN220362769U uses a vibrator for demoulding. Through the vibration, the adhesion between the concrete test block and the mold is weakened, thereby achieving easy demoulding. However, this device has also exposed some problems during actual use. First of all, as a mechanical equipment, the vibrator will inevitably wear or malfunction during long-term use. Once a malfunction occurs, it will not only affect the demoulding efficiency, but may also cause damage to the test block. Secondly, the structure of this demoulding auxiliary device is relatively complex, and once a malfunction occurs, it is also difficult to repair. In addition, since some accessories are not easy to obtain, once they need to be replaced, they may face high maintenance costs.

[0005] These problems will not only affect the service life of the demoulding device, but may also have an adverse impact on the production progress. Therefore, how to design a concrete test block demoulding auxiliary device with simple structure, easy maintenance and low cost has become an urgent problem to be solved in the industry.

[0021] A concrete test block demoulding device of the utility model is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0022] like Figure 1-3As shown, the utility model discloses a demoulding device for a concrete test block, which is mainly composed of a bracket 1, a support frame 2, a collision protrusion 3 and a buffer pad 4. The support frame 2 is located in the middle of the inner side of the bracket 1. The support frame 2 is a steel plate with a thickness of 5 mm, which is used to support the test mold. A collision space for the concrete test block is formed above the support frame 2, and a falling space for the concrete test block is formed below the support frame 2, so that the test mold can fall smoothly and hit the support frame 2 during the demoulding process, thereby realizing rapid demoulding. A collision protrusion 3 is fixed on the surface of the support frame 2, and one collision protrusion 3 is fixed every 50 mm. The collision protrusion 3 is evenly spaced along the surface of the support frame 2 to form a certain collision surface. To ensure that sufficient impact force can be generated when the test mold falls, the floating slurry on the surface of the concrete test block is effectively crushed, which not only improves the demoulding efficiency, but also avoids damage and errors caused by manual knocking. The shape of the collision protrusion 3 is hemispherical, which can effectively disperse the impact force and avoid damage to the concrete test block during the demoulding process. A buffer pad 4 is also provided at the bottom of the bracket 1. The buffer pad 4 is made of a 50 mm thick extruded polystyrene board and has good buffering performance and wear resistance. When the concrete test block falls off the support frame 2, the buffer pad 4 can effectively absorb the impact force, protect the concrete test block from damage, and also reduce noise.

[0023] In actual use, first, one end of the test mold is suspended in the air, and the other end is supported on the support frame 2 and in contact with the collision protrusion 3. When performing the demoulding operation, just loosen the suspended end, and the test mold will fall under the action of gravity and hit the collision protrusion 3 downward. The collision protrusion 3 can effectively crush the concrete slurry, so that the concrete test block is quickly separated from the test mold, and rapid demoulding is achieved. This process not only shortens the demoulding time, but also reduces the labor intensity of workers and improves work efficiency. Secondly, the device can withstand a certain impact force to ensure that it will not be deformed or damaged during long-term use. In addition, the concrete test block demoulding device also has the advantages of strong adaptability and easy operation. Due to the flexible and changeable setting of the support frame 2, it can adapt to the demoulding needs of concrete test blocks of different sizes and shapes. At the same time, the operation of the device is simple and easy to understand, and it can be used without complicated training, and it is also convenient for later maintenance.

[0024] In one embodiment of the utility model, the bracket 1 is mainly composed of four angle steels with a specification of ∠36*5. The four angle steels are arranged vertically in a rectangular manner, and the inner corners of each angle steel face inward, while the outer corners face outward, which is conducive to enhancing the load-bearing capacity of the angle steel and ensuring the stability of the entire bracket 1 structure. The rectangular space defined by the four angle steels not only provides stable support for the subsequent support frame 2 and buffer pad 4, but also ensures that the spatial layout of the entire bracket 1 structure is reasonable. In this rectangular space, the support frame 2 and the buffer pad 4 can be safely and firmly installed. Specifically, the shape of the support frame 2 is also rectangular, which fits the rectangular space formed by the four angle steels. The four corners of the support frame 2 are welded one by one with the inner corners of the four angle steels. This connection method is not only firm and reliable, but also can effectively prevent the support frame 2 from shaking or falling off during the force process. The buffer pad 4 is also rectangular in shape and is embedded and fixed in the rectangular space formed by the bottom of the four angle steels to ensure that the buffer pad 4 will not fall off or shift during long-term use. In addition to the support frame 2 and the buffer pad 4, a transversely arranged grille 5 is fixed between two adjacent angle steels. The grille 5 can effectively prevent the fallen concrete test blocks from leaking out from the side of the buffer pad 4 and hitting the ground, thereby avoiding damage to the ground and the surrounding environment. At the same time, the setting of the grille 5 can also play a certain protective role for the concrete test blocks, ensuring that they will not be damaged during transportation or storage.

[0025] In one embodiment of the utility model, a mounting plate 6 is also included, and four angle steels are welded to the upper surface of the mounting plate 6. A leveling assembly is arranged on the lower surface of the mounting plate 6 to cope with the uneven ground conditions in the construction site. The existence of the leveling assembly enables the device to maintain balance on the uneven ground, thereby ensuring the smooth progress of the work. Specifically, the leveling assembly consists of four height-adjustable support feet. The four support feet are distributed in the form of a rectangle at the four corners of the mounting plate 6, providing all-round support for the entire device. Each support foot has an independent height adjustment function and can be flexibly adjusted according to the actual situation of the ground. In more detail, the support foot is mainly composed of an outer sleeve 7 and an inner screw 8, which are tightly combined together by a threaded connection. A support boss 81 is provided at the lower end of the inner screw 8, which not only plays a supporting role, but also serves as an adjustment handle to facilitate the operation of workers. In actual use, workers can adjust the length of the inner screw 8 by rotating it, thereby controlling the height of the support foot in a single direction. In this way, workers can easily adjust the height of each support leg to balance the device as a whole. This not only improves the adaptability and stability of the device, but also reduces the difficulty and risk of workers working on uneven ground. At the same time, through precise threaded connections and height adjustment functions, the device can also achieve a more accurate and flexible leveling effect to meet the needs of different work scenarios.

[0026] In one embodiment of the utility model, a handle 9 is provided between two angle steels located on the short sides of the rectangle among four angle steels arranged vertically in a rectangle. The handle 9 can be used for easy grasping without causing inconvenience during transportation. Whether the device needs to be moved from one place to another or the angle needs to be adjusted, it can be completed by grasping the handle 9, which not only greatly saves the transportation time, but also reduces the safety risks during transportation.
