Description

Technical Field

[0001] This utility model belongs to the field of concrete block curing technology, specifically a rapid curing device for concrete specimens. Background Technology

[0002] The curing methods for concrete blocks mainly include standard curing and same-condition curing. In the current technology, same-condition curing involves placing the concrete specimen under the same curing conditions as the actual structure or component for curing. Standard curing can provide a stable temperature and humidity environment, which is conducive to the full hydration of concrete and thus obtains higher strength. Both methods require a sealed box to wrap the concrete blocks in order to carry out the above operations.

[0003] Currently available equipment often involves directly placing and clamping concrete inside or removing it by tilting it. This method often causes the concrete blocks to easily break during placement or removal, greatly reducing the yield of the finished concrete blocks.

[0004] Therefore, a rapid curing device for concrete specimens that facilitates the placement and removal of concrete blocks is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that concrete blocks are prone to cracking when placed or removed during use, a rapid curing device for concrete specimens is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The concrete specimen rapid curing device of this utility model includes a concrete curing box. First movable slots are provided on the bottom of both sides of the concrete curing box. The length of the first movable slot is less than the length of the concrete curing box. A first movable push block is movably inserted through the interior of the first movable slot. Auxiliary load-bearing slots are provided on both sides of the concrete curing box. Second movable slots are provided on both sides of the concrete curing box. Lifting load-bearing rods are movably inserted through the interior of the second movable slots. A movable traction rod is installed between two lifting load-bearing rods on the same side. The movable traction rod is used to control the height of the lifting load-bearing rods. An isolation plate is installed inside the concrete curing box. The auxiliary load-bearing slots are located on both sides of the second movable slots. The auxiliary load-bearing slots are in groups of two. Two opposing lifting load-bearing rods form a group. A load-bearing base is fixedly connected between two lifting load-bearing rods in the same group. The movable traction rod is used to adjust the movable height of the load-bearing base.

[0007] In some embodiments, the surface of the isolation plate is provided with a receiving groove for fitting a load-bearing base, the shape of the receiving groove and the shape of the load-bearing base are matched, and the receiving groove is not through-hole and is provided on both sides of the surface of the isolation plate.

[0008] In some embodiments, a protrusion is provided on the side of the load-bearing base near the concrete curing box. The protrusion is slidably connected inside the auxiliary load-bearing slot, which is used to assist in supporting the connection between the load-bearing base and the lifting load-bearing rod.

[0009] In some embodiments, a first leakage groove is provided on one side of the concrete curing box, and a second leakage groove is provided on the side of the concrete curing box away from the first leakage groove. The first leakage groove and the second leakage groove are both located below the horizontal level of the isolation plate.

[0010] In some embodiments, a third movable slot extends from both sides of the second movable slot. A torsion spring return shaft is installed at the top of the second movable slot. Both ends of the torsion spring return shaft movably pass through the third movable slot and are inserted into the inner wall of the concrete curing box. A sealing tension plate is rolled up and installed on the surface of the torsion spring return shaft. A positioning tension post is provided at one end of the sealing tension plate away from the torsion spring return shaft. Both ends of the positioning tension post pass through the interior of the third movable slot. The positioning tension post is fixedly engaged inside the lifting load-bearing rod. The length of the sealing tension plate is limited by the movable height of the lifting load-bearing rod inside the second movable slot. A limiting groove is provided at the bottom of the second movable slot. The limiting groove is matched with the shape of the lifting load-bearing rod and is used to assist in fixing the placement position of the lifting load-bearing rod.

[0011] In some embodiments, a heating coil is provided inside the concrete curing box. The heating coil is installed in the space between the isolation plate and the bottom of the inner cavity of the concrete curing box. A cleaning soft plate is installed between the two first movable push blocks. The cleaning soft plate is located at the bottom of the heating coil and overlaps with the bottom of the inner cavity of the concrete curing box. The cleaning soft plate is made of a soft elastic material. The cross-sectional shape of the cleaning soft plate is equal to the cross-sectional shape of the second leakage groove. The cleaning soft plate is used to block the inside of the second leakage groove. A sealing elastic strip is installed inside the first leakage groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Example 1

[0023] Please see Figures 1-3This utility model provides a rapid curing device for concrete specimens, including a concrete curing box 1. First movable slots 2 are provided on the bottom of both sides of the concrete curing box 1. The length of the first movable slots 2 is less than the length of the concrete curing box 1. A first movable push block 3 is movably inserted through the interior of the first movable slots 2. Auxiliary load-bearing slots 9 are provided on both sides of the concrete curing box 1. Second movable slots 7 are provided on both sides of the concrete curing box 1. Lifting load-bearing rods 5 are movably inserted through the interior of the second movable slots 7. A movable pull rod 6 is installed between the two lifting load-bearing rods 5 on the same side. The movable pull rod 6 is used to control the height of the lifting load-bearing rods 5. An isolation plate 10 is installed inside the concrete curing box 1. The auxiliary load-bearing slots 9 are located on both sides of the second movable slots 7. The auxiliary load-bearing slots 9 are in pairs. Two opposite lifting load-bearing rods 5 form a group. A load-bearing base 8 is fixedly connected between the two lifting load-bearing rods 5 in the same group. The movable pull rod 6 is used to adjust the movable height of the load-bearing base 8.

[0024] In this embodiment, the use of the concrete curing box 1 is described. When concrete blocks need to be placed inside the concrete curing box 1, the load-bearing base 8 is in a raised state when there is no heavy object pressing on its surface. This setting ensures that even when the load-bearing base 8 is installed, the surface cleaning of the isolation plate 10 will not be affected. When materials are placed inside the concrete curing box 1, they are first placed on top of the load-bearing base 8. At this time, the user can pull the movable pull rods 6 on both sides to gently place the materials into the concrete curing box 1. When it is necessary to remove the materials, the movable pull rods 6 can be pulled to facilitate the placement and removal of concrete blocks inside the concrete curing box 1, avoiding the problem of concrete block breakage during clamping or pouring.

[0025] Reference Figures 1-3 In the middle, the surface of the isolation plate 10 is provided with a receiving groove for fitting the load-bearing base 8. The shape of the receiving groove matches that of the load-bearing base 8. The receiving groove is not through and is provided on both sides of the surface of the isolation plate 10.

[0026] In this embodiment, by setting it up in this way, the installation of the load-bearing base 8 is avoided from taking up too much space inside the concrete curing box 1. At the same time, the load-bearing base 8 and the surface of the isolation plate 10 are on the same horizontal plane under pressure, which also ensures that the bottom of the concrete block will not deform due to local support.

[0027] Reference Figures 1-3 In the middle, a protrusion is provided on the side of the load-bearing base 8 near the concrete curing box 1. The protrusion is slidably connected inside the auxiliary load-bearing slot 9. The auxiliary load-bearing slot 9 is used to assist in supporting the connection between the load-bearing base 8 and the lifting load-bearing rod 5.

[0028] In this embodiment, by setting it up in this way, the load-bearing base 8 can effectively distribute the force of the lifting load-bearing rod 5 on the load-bearing base 8 during the lifting process by opening the auxiliary load-bearing slot 9, thus avoiding the problem of the device being easily broken during the material removal process.

[0029] Reference Figure 1-3 In the concrete curing box 1, a first leakage groove 11 is provided on one side, and a second leakage groove 12 is provided on the side of the concrete curing box 1 away from the first leakage groove 11. The first leakage groove 11 and the second leakage groove 12 are both located below the horizontal level of the isolation plate 10.

[0030] In this embodiment, the device is configured in such a way that the bottom of the concrete curing box 1 does not need to be disassembled during the cleaning process, which can effectively remove the concrete debris inside the concrete curing box 1 and facilitate the use of the device.

[0031] Reference Figures 1-3 In the second movable slot 7, third movable slots 13 extend from both sides. A torsion spring return shaft 14 is installed on the top of the second movable slot 7. Both ends of the torsion spring return shaft 14 pass through the third movable slot 13 and are inserted into the inner wall of the concrete curing box 1. A sealing tension plate 15 is rolled up on the surface of the torsion spring return shaft 14. A positioning tension column 16 is provided at the end of the sealing tension plate 15 away from the torsion spring return shaft 14. Both ends of the positioning tension column 16 pass through the interior of the third movable slot 13. The positioning tension column 16 is fixedly engaged inside the lifting load-bearing rod 5. The length of the sealing tension plate 15 is limited by the height of the lifting load-bearing rod 5 inside the second movable slot 7. A limit groove is provided at the bottom of the second movable slot 7. The limit groove is matched with the shape of the lifting load-bearing rod 5. The limit groove is used to assist in fixing the placement position of the lifting load-bearing rod 5.

[0032] In this embodiment, by setting it up in this way, it can be found that the torsion spring reset shaft 14, limited by its own properties, can roll up the sealing tension plate 15 when there is no weight pulling it, thereby driving the positioning tension column 16 to be lifted upward. As a result, the sealing tension plate 15 loses its sealing effect on the second movable slot 7. Therefore, the second movable slot 7 loses its sealing performance. During the process of lifting the load-bearing rod 5 upward, the water inside the concrete curing box 1 can be discharged at the same time, ensuring the drainage rate of the concrete curing box 1. At the same time, the two sides of the sealing tension plate 15 are fitted into the third movable slot 13, ensuring that the second movable slot 7 itself has a sealing effect when the load-bearing rod 5 is under pressure.

[0033] Reference Figures 1-3In the concrete curing box 1, a heating coil 18 is installed inside. The heating coil 18 is installed in the space between the isolation plate 10 and the bottom of the inner cavity of the concrete curing box 1. A cleaning soft plate 17 is installed between the two first movable push blocks 3. The cleaning soft plate 17 is located at the bottom of the heating coil 18 and overlaps with the bottom of the inner cavity of the concrete curing box 1. The cleaning soft plate 17 is made of soft elastic material. The cross-sectional shape of the cleaning soft plate 17 is equal to the cross-sectional shape of the second leakage groove 12. The cleaning soft plate 17 is used to block the inside of the second leakage groove 12. A sealing elastic strip is installed inside the first leakage groove 11. The sealing elastic strip is also embedded inside the first movable slot 2 and is used to block the gap between the first movable slot 2 and the first movable push block 3.

[0034] In this embodiment, the device is designed to effectively block the bottom of the concrete curing box 1 during use. All the sealing springs are deformable and expandable, and have the same effect as sealing rings. When cleaning is not required, the cleaning soft plate 17 acts as the sealing ring of the second leakage groove 12. When cleaning is required, the first movable push block 3 is slid back and forth under the limit of the first movable slot 2, and then the sealing spring in the first leakage groove 11 is removed, which can effectively clean the bottom of the concrete curing box 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
