Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a concrete test block demolding device. Background Technology

[0002] In modern concrete technology research and application, compressive strength testing is an essential step. This testing often involves forming concrete test molds, which necessitates a demolding process. Currently, the commonly used methods are demolding using an air compressor or manually. Demolding with an air compressor involves an air pump and air gun; the air compressor provides high-pressure gas to the air gun, which then blows the concrete specimen out of the mold. However, air pressure demolding has drawbacks, including high energy consumption and the difficulty of transporting the equipment. Manual demolding, on the other hand, is labor-intensive and can easily cause micro-cracks in the concrete block (test specimen) due to vibration during the setting process.

[0003] In addition, if the mold is not removed in time, it will stick to the mold, causing the specimen (test block) to be chipped or broken after being taken out. Due to sticking, the demolding efficiency is also not high, and the mold structure (mold of concrete test block) is also prone to cracking during the impact process, resulting in scrap. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a concrete test block demolding device with a simple structure, easy portability, and no site restrictions. It reduces the disturbance of the concrete test block to the rigid plastic mold during demolding, speeds up the demolding process, and improves work efficiency. To achieve the above objective, the technical solution of this utility model is as follows:

[0005] A concrete test block demolding device is used for demolding concrete test blocks. It includes a frame, a first support, a second support, a first support plate, a second support plate, and a buffer component. The frame is used to accommodate the mold of the concrete test block. The frame is a cavity structure with an upper opening and a lower opening. A limiting platform is provided on the inner edge of the lower opening of the frame to prevent the mold of the concrete test block from falling.

[0006] The first support and the second support are disposed below the frame. The first support is fixedly connected to the first end of the frame, and the second support is fixedly connected to the second end of the frame. The angle between the plane containing the lower end of the first support and the lower end of the frame is an obtuse angle, and the angle between the plane containing the lower end of the second support and the lower end of the frame is also an obtuse angle, such that the distance between the upper end of the first support and the upper end of the second support is less than the distance between the lower end of the first support and the lower end of the second support.

[0007] The lower end of the first support body is rotatably connected to the first support plate, and the lower end of the second support body is rotatably connected to the second support plate. The inner surfaces of the first support plate and the second support plate are each provided with a plurality of buffer components, which are used to buffer the concrete test block falling from the mold of the concrete test block.

[0008] The first support plate and the second support plate have an open state and a closed state. When the first support plate is open, the second support plate is naturally vertical. When the second support plate is closed, the first support plate and the second support plate are located in the same plane.

[0009] Furthermore, both the first support and the second support are quadrilateral structures.

[0010] Furthermore, there are multiple limiting platforms, which are spaced apart on the inner edge of the lower opening of the frame, and the upper surfaces of the multiple limiting platforms are on the same horizontal plane.

[0011] Furthermore, the limiting platform is a quadrilateral ring structure, and the periphery of the limiting platform contacts the inner edge of the lower opening of the frame.

[0012] Furthermore, the concrete test block demolding device also includes a handle, which is located on the outer side wall of the frame.

[0013] Furthermore, when the first support plate and the second support plate are in the closed state, there is a gap between the first support plate and the second support plate.

[0014] Furthermore, the first support body and the second support body are symmetrically arranged with respect to the center line of the frame; the first support plate and the second support plate are symmetrically arranged with respect to the center line of the frame.

[0015] The beneficial effects of this utility model are:

[0016] This utility model of concrete test block demolding device has a simple structure, is easy to carry, and is not limited by the site. It reduces the disturbance of the test block to the concrete test block during the demolding process of the rigid plastic test block, speeds up the demolding speed, allows the concrete test block to be cured in a standard manner as early as possible, and improves work efficiency. It also reduces energy consumption, overcomes the disadvantage of the equipment being difficult to move, and the effect of the demolded test block is consistent with that of the test block demolded by using an air pump and air gun, which greatly improves the work efficiency of on-site testing personnel.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the concrete test block demolding device of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0022] Reference Figure 1 and Figure 2 A concrete test block demolding device according to an embodiment of the present invention is used for demolding concrete test blocks, including a frame 101, a first support 1021, a second support 1022, a first support plate 1031, a second support plate 1032, and a buffer component 105.

[0023] The frame 101 is a mold for accommodating concrete test blocks. The frame 101 is a cavity structure with an upper opening 1011 and a lower opening 1012. A handle 106 can be provided on the outer side wall of the frame 101 for easy lifting.

[0024] A limiting platform 104 is provided on the inner edge of the lower opening 1012 of the frame 101. The limiting platform 104 is used to prevent the concrete test block mold from falling. Figure 2 As shown, there can be multiple limiting platforms 104, which are spaced apart and arranged along the inner edge of the lower opening 1012 of the frame 101. The upper surfaces of the multiple limiting platforms 104 are on the same horizontal plane. Alternatively, the limiting platform 104 can be a quadrilateral ring structure, with its perimeter contacting the inner edge of the lower opening 1012 of the frame 101. When the upper surface of the limiting platform 104 contacts the mold of the concrete test block, it prevents the mold of the concrete test block from falling off. The limiting platform 104 can be fixed to the frame 101 by welding or screws; of course, the limiting platform 104 can also be integrally formed with the frame 101.

[0025] The first support 1021 and the second support 1022 are disposed below the frame 101. The first support 1021 is fixedly connected to the first end of the frame 101, and the second support 1022 is fixedly connected to the second end of the frame 101. The angle between the plane containing the lower end of the first support 1021 and the frame 101 is an obtuse angle, and the angle between the plane containing the lower end of the second support 1022 and the frame 101 is also an obtuse angle. This makes the distance between the upper ends of the first support 1021 and the upper ends of the second support 1022 smaller than the distance between the lower ends of the first support 1021 and the lower ends of the second support 1022, thus facilitating the drop of the concrete test block. For example, the first support 1021 and the second support 1022 can be plate-like structures, thus forming an inverted V-shaped structure.

[0026] The first support 1021 and the second support 1022 can both be quadrilateral or triangular structures, which can effectively improve the stability of the support. When the first support 1021 and the second support 1022 are quadrilateral structures, an equilateral trapezoidal structure is preferred.

[0027] In a preferred embodiment, the lower end of the first support 1021 is rotatably connected to the first support plate 1031, and the lower end of the second support 1022 is rotatably connected to the second support plate 1032. Both the first and second support plates 1031 and 1032 have several buffer components 105 on their inner surfaces. These buffer components 105 are used to cushion concrete blocks falling from the mold. The buffer components 105 provide vibration damping and protection for the concrete blocks, preventing damage from rigid impacts. The longitudinal section of the buffer component 105 is preferably trapezoidal, which facilitates the removal of the concrete blocks while providing effective cushioning. Multiple buffer components 105 can be provided on the inner surface of the first support plate 1031, and these components can be arranged parallel to each other at intervals. Similarly, multiple buffer components 105 can be provided on the inner surface of the second support plate 1032, and these components can be arranged parallel to each other at intervals.

[0028] The first support plate 1031 and the second support plate 1032 have an open state and a closed state. When the first support plate 1031 and the second support plate 1032 are both in a natural vertical position, and when the first support plate 1031 and the second support plate 1032 are both located in the same plane.

[0029] Preferably, when the first support plate 1031 and the second support plate 1032 are in the closed state, there may be a gap between them. For example, when the first support plate 1031 and the second support plate 1032 are in the closed state, the gap between them is 3-5 cm, which facilitates the opening of the first support plate 1031 and the second support plate 1032.

[0030] In this embodiment, the lower end of the first support 1021 can be rotatably connected to the first support plate 1031 by a hinge, and the lower end of the second support 1022 can be rotatably connected to the second support plate 1032 by a hinge. In other embodiments, the lower end of the first support 1021 can also be rotatably connected to the first support plate 1031 by other hinge methods, and the lower end of the second support 1022 can also be rotatably connected to the second support plate 1032 by other hinge methods.

[0031] The first support body 1021 and the second support body 1022 can be symmetrically arranged with respect to the center line of the frame 101; the first support plate 1031 and the second support plate 1032 can be symmetrically arranged with respect to the center line of the frame 101; that is, the first support body 1021 and the second support body 1022 are symmetrical with respect to the center line of the frame 101, and the first support plate 1031 and the second support plate 1032 are symmetrical with respect to the center line of the frame 101.

[0032] The first support body 1021 and the second support body 1022 are provided to support the frame 101 and provide a landing space for the concrete test block to fall off. Below the first support body 1021 and the second support body 1022, the first support plate 1031 and the second support plate 1032 are provided to be openable and closable. When the first support plate 1031 and the second support plate 1032 are closed, they can be used to receive the falling concrete test block. When the first support plate 1031 and the second support plate 1032 are open, it is convenient to remove the concrete test block completely.

[0033] The working process of the concrete test block demolding device is as follows: The concrete mold containing the concrete test block is placed into the upper opening 1011 of the frame 101. The concrete mold and concrete test block automatically fall into the frame 101 under their own weight. When the concrete mold contacts the limiting platform 104, the limiting platform 104 stops the concrete mold from falling further. The concrete test block inside the mold continues to fall onto the buffer components 105 of the first support plate 1031 and the second support plate 1032 due to gravity and inertia, thus separating the concrete test block from the concrete mold. Then, by lifting the handle 106, the frame 101 is moved upwards, and the first support plate 1031 and the second support plate 1032 naturally open, allowing the concrete test block to slowly fall to the ground. Finally, the concrete mold is removed from the frame 101, allowing for early standard curing of the concrete test block. The limiting platform 104 supports the concrete mold and limits its movement. In this article, the concrete mold refers to the mold for the concrete test block. In this embodiment, the cross-section of the frame 101 is square, and the concrete mold is also square. The concrete mold can slide up and down inside the frame 101.

[0034] The concrete block demolding devices described in the above embodiments are simple in structure, easy to carry, and not limited by site conditions. They reduce the disturbance to the concrete blocks caused by rigid plastic molds during demolding, accelerate the demolding process, and allow for earlier standard curing of the concrete blocks, thus improving work efficiency. They also reduce energy consumption, overcome the disadvantages of difficult equipment handling, and produce concrete block demolding results consistent with those obtained using an air pump and air gun, significantly improving the work efficiency of on-site testing personnel.

[0035] The concrete specimen demolding device described above was applied to a project for verification. The project produced 4000 sets of concrete specimens. The results showed that the application of this quick-release technology significantly improved the work efficiency of on-site testing personnel, enhanced the quality of specimen forming, increased the accuracy of concrete engineering testing, and reduced construction costs. Compared to traditional demolding techniques, it saved approximately 50% on labor costs and approximately 80% on equipment costs. The verification of this quick-release technology in this project generated direct economic benefits of approximately 106,000 yuan, achieving significant economic benefits.

[0036] It should be noted that, unless otherwise specified, the above embodiments and features can be combined with each other.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
