Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete test block demolding technology, and in particular to a demolding device. Background Technology
[0002] Concrete test blocks are an important test product for concrete performance testing. Their quality greatly affects the test results. There are two types of molds for making concrete test blocks: steel molds and plastic molds. Most construction sites use plastic molds.
[0003] Currently, the demolding of concrete test blocks is generally done manually. The manual demolding method mainly involves knocking on the mold or manually bumping the mold containing the test block to separate the test block from the mold. This method is not very practical and is prone to damaging the mold. Utility Model Content
[0004] The main purpose of this utility model is to provide a demolding device that is not easily damaged by the mold and has good practicality.
[0005] To achieve the above objectives, the present invention proposes a demolding device, which is installed on the ground, characterized in that the demolding device comprises:
[0006] At least two clamping parts, the two clamping parts being movably disposed relative to each other in a first direction and spaced apart from the ground;
[0007] At least two of the aforementioned support legs, each support leg having one end corresponding to one of the aforementioned clamping portions, and the other end being movably disposed relative to the ground; and,
[0008] An adjustment component is disposed between the two clamping parts. The adjustment component includes an adjustment part, the two ends of which are respectively disposed corresponding to the two clamping parts. At least one of the clamping parts is telescopically disposed relative to the adjustment part in a first direction to adjust the distance between the two clamping parts to fix molds of different sizes.
[0009] In one embodiment, the clamping part is provided with an adjustment hole extending along a first direction, and the adjustment part is inserted into the adjustment hole.
[0010] In one embodiment, the adjusting hole and the adjusting part are connected by a threaded connection.
[0011] In one embodiment, the two clamping portions are retractably disposed relative to the adjusting portion in a first direction.
[0012] In one embodiment, the adjustment assembly further includes an adjustment sleeve, which is fitted onto the middle portion of the adjustment part.
[0013] In one embodiment, the adjustment assembly further includes an anti-slip surface provided on the adjustment sleeve.
[0014] In one embodiment, four clamping parts are provided, and correspondingly, four adjusting components are provided, with each adjusting component disposed between two adjacent clamping parts.
[0015] In one embodiment, each of the clamping parts is provided with a protective plate.
[0016] In one embodiment, a receiving device is provided below the clamping part and spaced apart from the ground.
[0017] In one embodiment, the receiving device includes a net disposed on the support leg.
[0018] The technical solution of this utility model supports and fixes the mold by employing the clamping parts and the support legs. The mold can be demolded by applying a small force to the mold using the weight of the test block itself, or by using an air gun. Specifically, the mold has holes for connecting an air gun to push the test block out of the mold, allowing it to be easily removed without damaging the mold. This improves the mold's utilization and turnover rate, while also enhancing the molding quality of the test block. Furthermore, the adjustment component allows for adjustment of the distance between the two clamping parts, accommodating different mold models and improving practicality. Attached Figure Description

[0030] Concrete test blocks are an important test product for concrete performance testing. Their quality greatly affects the test results. There are two types of molds for making concrete test blocks: steel molds and plastic molds. Most construction sites use plastic molds.
[0031] Currently, the demolding of concrete test blocks is generally done manually. The manual demolding method mainly involves knocking on the mold or manually bumping the mold containing the test block to separate the test block from the mold. This method is not very practical and is prone to damaging the mold.
[0032] This utility model proposes a demolding device, which aims to provide a demolding device that is not easily damaged by the mold and has good practicality.
[0033] In one embodiment of this utility model, the demolding device 100 is disposed on the ground. The demolding device 100 includes at least two clamping parts 1, at least two support legs 2, and an adjustment component 3. The two clamping parts 1 are movably disposed relative to each other in a first direction and are spaced apart from the ground. One end of each support leg 2 is disposed corresponding to a clamping part 1, and the other end is movably disposed relative to the ground. The adjustment component 3 is disposed between the two clamping parts 1. The adjustment component 3 includes an adjustment part 31, the two ends of which are respectively disposed corresponding to the two clamping parts 1. At least one clamping part 1 is retractable relative to the adjustment part 31 in the first direction to adjust the distance between the two clamping parts 1 to fix molds of different sizes.
[0034] The technical solution of this utility model supports and fixes the mold by using the clamping part 1 and the support leg 2. The mold can be demolded by applying a small force to the mold using the weight of the test block itself, or by using an air gun. Specifically, the mold has holes for connecting an air gun to push the test block out of the mold, allowing it to be easily removed without damaging the mold. This improves the mold's utilization and turnover rate, and also enhances the molding quality of the test block. Furthermore, the adjustment component 3 allows for adjustment of the distance between the two clamping parts 1, accommodating different mold models and improving practicality.
[0035] It is understandable that the specific way in which the support leg 2 is movable relative to the ground can be by setting a serration at the end of the support leg 2 away from the clamping part 1, so as to contact the ground and increase the friction between the support leg and the ground. This will keep the clamping part 1 stable while also making it easy to move the support leg 2 away from the ground, so as not to fix it to the ground and to make it convenient and flexible to use. Alternatively, a sharp corner can be set at the end of the support leg 2 away from the clamping part 1, so as to contact the ground. If there is soft soil, it can be inserted into the ground for placement, providing stability and making it easy to move.
[0036] It is understood that the adjustment part 31 can be configured using a cylinder, for example, by connecting one end of the cylinder to one side of one of the clamping parts 1 and the other end (the output end of the cylinder) to another clamping part 1, and by activating the cylinder, the distance between the two clamping parts 1 can be adjusted in the first direction; or by using a snap button and multiple snap slots, for example, by setting a snap button on one of the clamping parts 1 and setting multiple snap slots on another clamping part 1, and by pressing the snap button to fit the snap slots at different positions, the distance between the two clamping parts 1 can be changed.
[0037] It is understood that this application does not impose specific restrictions on the form of the clamping part 1. It can be plate-shaped, strip-shaped, etc.; it can be square, arc-shaped, angled, or irregular-shaped, etc., as long as it can be adapted to different styles of molds for demolding.
[0038] Furthermore, in one embodiment, the clamping part 1 is provided with an adjustment hole 11 extending along a first direction, and the adjustment part 31 is inserted into the adjustment hole 11.
[0039] Thus, by providing the adjustment hole 11, the adjustment part 31 can be placed inside the adjustment hole 11, reducing the danger of exposed structural components and also protecting the structural components.
[0040] Furthermore, in one embodiment, the adjusting hole 11 is threadedly connected to the adjusting part 31.
[0041] Thus, with the threaded connection, the user only needs to rotate the device to adjust the distance between the two clamping parts 1, making the operation simple and convenient.
[0042] In one embodiment, the two clamping parts 1 are retractably disposed relative to the adjusting part 31 in a first direction.
[0043] This improves the flexibility of the clamping part 1, facilitates the movement of the two clamping parts 1, and the retractable clamping part 1 can make more efficient use of space and reduce the possibility of interference with other equipment or obstacles.
[0044] It is understood that the two clamping parts 1 can be retracted relative to the adjusting part 31 by using a bidirectional screw. The two ends of the bidirectional screw are respectively inserted into the adjusting hole 11. By turning the bidirectional screw, the two clamping parts 1 can be moved closer to each other or further away from each other.
[0045] In one embodiment, the adjustment component 3 further includes an adjustment sleeve 32, which is fitted onto the middle part of the adjustment portion 31.
[0046] Thus, the adjustment sleeve 32 provides the operator with a hand operating area, thereby facilitating the adjustment part 31.
[0047] In one embodiment, the adjustment component 3 further includes an adjustment sleeve 32 with an anti-slip surface.
[0048] This design increases the friction on the operator's hand during adjustment, making it easier to rotate the adjustment part 31 and making operation more convenient.
[0049] It is understood that the anti-slip surface may be engraved with patterns (such as horizontal or vertical lines); or it may have several raised dots.
[0050] In one embodiment, four clamping parts 1 are provided, and correspondingly, four adjusting components 3 are provided, with each adjusting component 3 disposed between two adjacent clamping parts 1.
[0051] Thus, by setting up the four clamping parts 1, the spacing between them can be adjusted more flexibly, thereby expanding the applicability of the mold and improving its practicality.
[0052] It should be explained that the four clamping parts 1 can all be designed as right angles, forming a square. Four adjusting parts 31 are provided to assemble the four clamping parts 1. The direction perpendicular to the first direction is designated as the second direction. That is, by simultaneously rotating two adjusting parts 31 in the first direction, the clamping parts 1 can be moved closer or further apart in the second direction; conversely, by simultaneously rotating two adjusting parts 31 in the second direction, the clamping parts 1 can be moved closer or further apart in the first direction, thus achieving flexible use.
[0053] Furthermore, in some embodiments, each of the clamping parts 1 is provided with a protective plate 12.
[0054] This design serves to protect the mold and improve its safety during use.
[0055] It is understood that the protective plate 12 can be set on the upper side of the clamping part 1, and the mold containing the concrete test block is inverted on the upper side of the clamping part 1. Since the mold itself has a certain thickness, the side of the inverted mold can be placed on the upper side of the clamping part 1, completely exposing the test block to be demolded. At this time, the four clamping parts 1 have been adjusted in size, and the protective plate 12 protects the outer peripheral wall of the mold. When a small force is struck or a gas gun is used for demolding, the test block can be detached from the mold.
[0056] In one embodiment, a receiving device 4 is provided below the clamping part 1 and spaced apart from the ground.
[0057] In this way, the receiving device 4 can be used to receive and catch the demolded test block, reducing damage to the test block.
[0058] It is understood that the receiving device 4 can be set in the form of a slide, that is, a slide is set on the lower side of the clamping part 1, and the slide has a certain angle with the ground to facilitate the sliding of the test block. At the same time, the material of the slide is set to be elastic, such as highly elastic silicone, which provides cushioning for the test block and can also be adjusted with the adjustment of the clamping part 1.
[0059] Furthermore, in one embodiment, the receiving device 4 includes a net 41, which is disposed on the support leg 2.
[0060] Thus, the net 41 serves to facilitate the receiving of demolded test blocks and also cushions the falling test blocks during the receiving process.
[0061] It is understood that the connection method of the net 41 can be by using cable ties; or by installing collars at the four corners of the net 41, with the collars passing through the support legs 2 and fixed by bolts or pins.
[0062] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
