Abstract
Description
Technical Field
[0001] The present application relates to the technical field of concrete performance testing, and in particular to a concrete test block rapid demoulding device. Background Art
[0002] Concrete is a widely used building material, and its performance seriously affects the safety and service life of the building. Therefore, in order to verify the performance of concrete, certain tests need to be carried out on the concrete to obtain experimental data to analyze the performance of concrete. Before testing the performance of concrete, the concrete needs to be sampled. The sampled concrete is also called a concrete test block.
[0003] At the concrete mixing outlet or pouring site, samples are taken and poured into a mold composed of four side panels to make concrete test blocks, which then need to be demoulded. The concrete blocks are then subjected to a compression test to obtain test data, thereby verifying whether the strength of the concrete meets the requirements.
[0004] The above-mentioned prior art solutions have the following defects: when demolding the concrete test block, the concrete test block is generally stuck in the mold, and the mold needs to be manually shaken back and forth to make the concrete test block fall off due to inertia. During the process, not only does the operator need to bend over to shake the mold, but the existing mold does not have a suitable gripping point, making it difficult for the operator to grip the mold and shake it. Therefore, it is very inconvenient to demold the concrete test block. Utility Model Content
[0005] In order to make demoulding of concrete test blocks easier and more convenient, the present application provides a quick demoulding device for concrete test blocks.
[0006] The above technical objectives of this application are achieved through the following technical solutions:
[0007] A quick demoulding device for concrete test blocks comprises a mold, wherein the mold is connected up and down, and pull ropes are arranged on opposite sides of the mold. A connecting structure is arranged at the connection between the mold and the pull rope, and the pull rope is connected to the mold through the connecting structure. The connecting structure comprises a clamping block and a clamping rod. The clamping blocks are arranged on opposite sides of the mold, and the clamping blocks are arranged at the upper position of the mold. The clamping block is provided with a through hole connecting the upper surface and the lower surface of the clamping block. One end of the pull rope passes through the through hole from top to bottom and is connected to the clamping rod, and the pull rope is fixedly connected to the middle position of the clamping rod.
[0008] By adopting the above scheme, when it is necessary to demold the concrete test block, the operator can pull the pull rope and shake the pull rope back and forth. The pull rope is tightened to press the clamping rod tightly against the lower surface of the clamping block, so that the clamping rod drives the clamping block to move with the clamping rod, thereby driving the mold to move and shake left and right, gradually causing the concrete test block to fall off the mold, thereby completing the demolding of the concrete test block. During this process, the operator does not need to bend over to shake the mold, and the pull rope provides a gripping position for the operator, so that the operator can demold the concrete test block more easily and conveniently.
[0009] Optionally, an ear plate is fixedly connected to the side of the clamping block facing away from the mold, the clamping block is connected to the upper part of the ear plate, the ear plate is perpendicular to the clamping block, and the ear plate is parallel to the surface of the clamping block on one side connected to the mold.
[0010] By adopting the above technical solution, the ear plate provides a suitable gripping point for the operator, and the operator can not only shake the mold by grasping the pull rope to demould the concrete test block, but also shake and lift the mold by grasping the ear plate.
[0011] Optionally, a cylindrical end is fixedly connected to the side of the ear plate facing away from the mold.
[0012] By adopting the above technical solution, the edges and corners of the ear plate are rounded, so that the operator can grip the ear plate more comfortably.
[0013] Optionally, a pull ring is provided at one end of the pull rope facing away from the mold.
[0014] By adopting the above technical solution, the pull rope can be driven by pulling the pull ring, thereby increasing the force area of the operator's hand when demolding the concrete test block, thereby reducing the pressure on the hand, making the operator more comfortable when demolding the concrete test block.
[0015] Optionally, the outer side of the pull ring is wrapped with a sponge pad.
[0016] By adopting the above technical solution, the force-bearing area of the operator's hand when demolding the concrete test block is further increased, so that the operator is more comfortable when demolding the concrete test block.
[0017] Optionally, a connecting column is provided at one end of the pull rope connected to the pull ring, a thread is provided on the outer circumferential surface of the connecting column, a thread groove is provided on the pull ring, the pull rope and the pull ring are connected by threads, and the diameter of the connecting column is smaller than the diameter of the through hole.
[0018] By adopting the above technical solution, when the pull rope or pull ring needs to be replaced, the connecting column can be unscrewed in the threaded groove, and then the corresponding object can be replaced without replacing the entire object. At the same time, after the pull rope is separated from the pull ring, the pull rope and the connecting column can slide out at the through hole, thereby separating the pull rope from the card block to prevent the pull rope from causing obstruction during the injection molding of the concrete specimen.
[0019] Optionally, the clamping block is provided with a clamping slot, the length of which is longer than the length of the clamping rod, and the clamping slot is arranged at the port where the through hole is connected to one end of the connecting rod.
[0020] By adopting the above technical solution, when the concrete test block is demoulded, the clamping block is stuck in the clamping groove, thereby preventing the clamping block from moving and causing accelerated wear of the pull rope and the clamping rod, thereby increasing the service life of the demoulding device.
[0021] Optionally, an inclined surface is provided at the notch of the card slot, and when the pull rope is tightened, the card block slides into the card slot along the inclined surface.
[0022] By adopting the above technical solution, when the concrete test block is demoulded and the clamping rod is not parallel to the clamping slot, the pull rope is tightened, and the clamping rod is forced to rotate along the inclined surface until the clamping rod enters the clamping slot, so that the clamping rod can automatically enter the clamping slot.
[0023] Optionally, a rope groove is provided on the upper surface of the ear plate.
[0024] By adopting the above technical solution, when the concrete test block is not demoulding, the draw rope can be stored in the rope groove to avoid the draw rope being placed randomly and causing obstruction to other processes.
[0025] In summary, this application has the following technical effects:
[0026] By setting a pull rope and a connecting structure, the operator can pull the pull rope to drive the mold to shake and lift, so that the operator does not need to bend over, and a suitable gripping position is provided for the operator, making it easier and more convenient to demould the concrete test block;
[0027] The pull ring is provided to increase the force area of the operator's hand when demolding the concrete test block, thereby reducing the pressure on the operator's hand and making the operator more comfortable when demolding the concrete test block;
[0028] The sponge pad is provided to further increase the force bearing area of the operator's hand when demolding the concrete test block, thereby making the operator more comfortable when demolding the concrete test block. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0034] The present application is further described in detail below in conjunction with the accompanying drawings.
[0035] Reference Figure 1 A concrete test block rapid demoulding device includes a mold 1, a mold groove 11 connected to the lower surface is opened on the upper surface of the mold 1, and a connecting structure is provided on opposite sides of the mold 1, and the connecting structure is connected to a pull rope 2. Concrete is poured in the mold groove 11, and after the concrete test block is solidified, the pull ropes 2 on both sides of the mold 1 are pulled to shake the mold 1 left and right and lift the mold 1, so that the concrete test block is separated from the mold 1, thereby completing the demoulding of the concrete test block.
[0036] Reference Figure 1 and Figure 2The connection structure includes a clamping block 4 and a clamping rod 3. Two clamping blocks 4 are provided. The two clamping blocks 4 are respectively provided on opposite sides of the mold 1, and the clamping blocks 4 are fixedly connected to the upper position of the mold 1. A through hole 41 connected to the lower surface of the clamping block 4 is provided on the upper surface of the clamping block 4. One end of the pull rope 2 passes through the through hole 41 from top to bottom, and one end of the pull rope 2 passing through the through hole 41 is fixedly connected to the clamping rod 3, and the pull rope 2 is connected to the center position of the clamping rod 3. A clamping groove 42 is provided on the lower surface of the clamping block 4, located at the position where the through hole 41 is provided in the clamping block 4. The clamping groove 42 is a rectangular groove, and the length of the clamping groove 42 is longer than the length of the clamping rod 3. Inclined surfaces 421 inclined to the two long sides of the clamping groove 42 are provided on opposite sides of the notch of the clamping groove 42, so that the clamping rod 3 can slide into the clamping groove 42 along the inclined surface 421. When the concrete test block needs to be demoulded, the pull rope 2 is pulled, so that the pull rope 2 gives the clamping rod 3 an upward force, so that the clamping rod 3 generates a force to squeeze the inclined surface 421, so that the clamping rod 3 slides along the slope into the clamping groove 42, so that the clamping block 4 is fixed in the clamping groove 42, so that the clamping rod 3 drives the clamping block 4 to move, and then drives the mold 1 to move, so that the mold 1 is separated from the concrete test block. At the same time, because the clamping rod 3 is fixed in the clamping groove 42, the clamping rod 3 is prevented from rotating during the demoulding process of the concrete test block, which causes the friction between the clamping rod 3 and the clamping block 4 to increase, and it may also cause the pull rope 2 to rotate and tighten, thereby reducing the strength of the pull rope 2.
[0037] Reference Figure 2 The ear plate 5 is fixedly connected to the side of the clamping block 4 away from the mold 1. The clamping block 4 is perpendicular to the ear plate 5 and connected to the upper position of the ear plate 5. A cylindrical end 51 is fixedly connected below the ear plate 5. The cylindrical end 51 makes the edge of the lower side of the ear plate 5 disappear and makes the lower side of the ear plate 5 more rounded. The operator can also directly use the ear plate 5 as a grip point to shake and lift the mold 1. The cylindrical end 51 makes it more comfortable for the operator to grip the ear plate 5.
[0038] Reference Figure 2 and Figure 3 A rope groove 52 is provided on the upper surface of the cylindrical end 51, and a rope guide groove 43 connecting the rope groove 52 and the through hole 41 is provided on the upper surface of the clamping block 4. The operator can place the pull rope 2 along the rope guide groove 43 into the rope groove 52 to prevent the pull rope 2 from being placed randomly and affecting other processes.
[0039] Reference Figure 4, a pull ring 6 is connected to the end of the pull rope 2 away from the clamping rod 3, and the end of the pull rope 2 connected to the pull ring 6 is fixedly connected to the connecting column 21, and the diameter of the connecting column 21 is smaller than the diameter of the through hole 41. The pull rope 2 is fixedly connected to one end of the connecting column 21, and a thread is provided on the circumferential surface of the connecting column 21. The pull ring 6 is connected to a threaded sleeve 62, and the threaded sleeve 62 is provided with a threaded groove. The connecting column 21 is screwed into the threaded groove, and the pull ring 6 is wrapped with a sponge pad 61. When the concrete test block needs to be demoulded, the operator can drive the pull rope 2 to move by pulling the pull ring 6. The sponge pad 61 can increase the contact area of the operator's hand, thereby reducing the pressure on the operator's hand, making it more comfortable for the operator to demould the concrete test block. When the pull rope 2 or the pull ring 6 is damaged, the connecting column 21 can be screwed out of the threaded groove, and then only the corresponding accessories need to be replaced, and the connecting column 21 and the pull rope 2 can be passed through the through hole 41 to separate the pull rope 2 from the clamping block 4.
[0040] The specific implementation principle of the present application is as follows: when it is necessary to demould the concrete test block, the operator holds the two pull rings 6 with both hands, and then shakes them back and forth while lifting them upward, so that the pull rings 6 drive the pull rope 2 to move, and the pull rope 2 drives the clamping rod 3 to slide into the clamping groove 42 along the inclined surface 421, so that the clamping rod 3 drives the clamping block 4 and the mold 1 to shake, so that the concrete test block is slowly separated from the mold 1 until the demoulding is completed. At the same time, the operator can also directly grasp the ear plate 5 and shake it. Compared with the existing concrete test block mold, this concrete test block quick demoulding device provides a gripping point for the operator, and by pulling the pull rope 2, the operator can quickly demould the concrete test block without bending over, making the demoulding of the concrete test block easier and more convenient.
[0041] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
