Description

Technical Field

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

[0002] A concrete test block is a block-shaped specimen taken from the same batch of concrete after pouring and made into a standard shape. It is used for testing compression, flexural strength, compressive strength, and other physical properties. To make a concrete test block, concrete is added to a mold, and after it hardens, the block is removed from the mold.

[0003] Currently, the separation of the mold and the test block is usually achieved by vibrating the mold. This method separates the test block from the inner wall of the mold. Although this method can remove the test block from the mold, if the vibration of the test block in the mold is excessive, cracks are likely to appear on the surface of the test block in the mold. Moreover, the vibration of the mold causes the test block to separate from the inner wall of the mold gradually, which takes a long time. This method results in low demolding efficiency of the test block.

[0004] Therefore, we propose a concrete test block demolding device. Utility Model Content

[0030] like Figures 1-5 As shown, an embodiment of this utility model proposes a concrete test block demolding device, including a concrete test block mold 1 and a demolding component 2 disposed on the upper surface of the concrete test block mold 1. The concrete test block mold 1 is used to make concrete into a target shape, and the demolding component 2 is used to quickly remove the concrete made into a test block from the concrete test block mold 1.

[0031] By replacing the traditional vibration demolding method with the demolding component 2 and the concrete test block mold 1, the problem of cracks appearing on the surface of the concrete test block due to excessive vibration on the inner side of the concrete test block mold 1 can be avoided, and the demolding efficiency of the concrete test block can also be improved.

[0032] The concrete test block mold 1 includes a base plate 11, a first side plate 12, a second side plate 13, a rotating block 14, a groove 15, and rounded corners 16. The demolding assembly 2 includes a top cover 21, a first receiving groove 22, a second receiving groove 23, a limiting groove 24, a demolding top block 25, a moving block 26, a push plate 27, a cylinder 28, and a carrying handle 29.

[0033] The first side plate 12 and the second side plate 13 are both disposed above the base plate 11. There are two of each of the first side plate 12 and the second side plate 13. The two first side plates 12 and the second side plates 13 are arranged in a rectangular shape. The rotating block 14 is disposed on the lower end face of the first side plate 12 and the second side plate 13. The slot 15 is opened at the four corners of the upper end face of the base plate 11. The rotating blocks 14 on the first side plate 12 and the second side plate 13 are rotatably connected to the slots 15 at the four corners of the upper end face of the base plate 11 in sequence. The rounded corners 16 are disposed at the corners of the upper end face of the base plate 11.

[0034] The rounded corners 16 ensure that the first side plate 12 and the second side plate 13 do not move against the base plate 11 during rotation. This also ensures that the lower surfaces of the first side plate 12 and the second side plate 13, which are flipped to the upper surface of the vertical base plate 11, are tightly attached to the upper surface of the base plate 11, thereby ensuring the sealing of the concrete test block mold 1 when making the concrete test block.

[0035] The top cover 21 is disposed on the upper end face of the first side plate 12 and the second side plate 13. The first receiving groove 22 and the second receiving groove 23 are formed inside the top cover 21. There are four first receiving grooves 22 arranged in a cross shape, and all four first receiving grooves 22 communicate with the second receiving grooves 23. The limiting groove 24 is formed on the lower end face of the top cover 21. There are four limiting grooves 24, and the four limiting grooves 24 communicate with the four first receiving grooves 22 respectively.

[0036] It should be noted that the top cover 21 has a T-shaped cross-section, and the protrusion of the top cover 21 is inserted into the upper end face of the concrete test block mold 1. This not only seals the concrete test block mold 1, but also flattens the concrete inside the concrete test block mold 1, thereby improving the molding quality of the concrete test block.

[0037] The demolding top block 25 is slidably connected to the inner side of the limiting groove 24, the moving block 26 is slidably connected to the inner side of the second receiving groove 23, the push plate 27 is disposed inside the first receiving groove 22, and the two ends of the push plate 27 are rotatably connected to the demolding top block 25 and the moving block 26 respectively. The cylinder 28 is disposed on the upper end face of the top cover 21, and the output end of the cylinder 28 is connected to the moving block 26 inside the second receiving groove 23. The handle 29 is disposed on both sides of the upper end face of the top cover 21.

[0038] The second receiving groove 23 has a rectangular cross-section, and the shape and size of the moving block 26 are adapted to the second receiving groove 23. The rectangular cross-section of the second receiving groove 23 makes the movement of the moving block 26 more stable in the vertical direction.

[0039] The second side plate 13 has hanging plates 3 at both ends and locking plates 4 on both sides. The locking plates 4 have a U-shaped cross-section. The side wall of the hanging plate 3 opposite to the second side plate 13 and the side wall of the second side plate 13 opposite to the hanging plate 3 are provided with arc-shaped spring plates 5. The left and right side walls of the locking plates 4 are provided with arc-shaped grooves 6. The locking plates 4 are engaged inside the hanging plate 3 at one end of the second side plate 13, and the hanging plate 3 and the arc-shaped spring plates 5 on the second side plate 13 are engaged in the arc-shaped grooves 6 on the locking plates 4.

[0040] The first side plate 12 and the second side plate 13, which are perpendicular to the base plate 11, can be locked in position by the setting of the hanging plate 3 and the setting of the arc-shaped spring plate 5 and the arc-shaped groove 6 can lock the position of the locking plate 4 inserted on the hanging plate 3.

[0041] The two first side plates 12 are located between the two second side plates 13, and the two ends of the first side plates 12 press against the two second side plates 13 respectively.

[0042] Working principle:

[0043] First, flip the first side plate 12 and the second side plate 13 upwards, so that the first side plate 12 and the second side plate 13 are flipped above the bottom plate 11, with the first side plate 12 and the second side plate 13 perpendicular to the upper end face of the bottom plate 11, and the lower end faces of the first side plate 12 and the second side plate 13 pressing against the upper end face of the bottom plate 11. Then, the locking plate 4 is engaged in the hanging plate 3 on the second side plate 13. At this time, the hanging plate 3 and the arc-shaped elastic plate 5 on the second side plate 13 are engaged in the arc-shaped groove 6 on the locking plate 4. Then, concrete is poured into the molding space enclosed by the bottom plate 11 and the first side plate 12 and the second side plate 13. Finally, the top cover 21 is placed on the first side plate. 12. On the upper surface of the second side plate 13, wait for the concrete to solidify. When it is necessary to demold the formed concrete test block, push the locking plate 4 upward to separate the locking plate 4 from the hanging plate 3. Then, start the cylinder 28. The cylinder 28 drives the moving block 26 to move down along the second receiving groove 23. The movement of the moving block 26 causes one end of the push plate 27 connected to it to move down. The downward movement of one end of the push plate 27 will push the demolding top block 25 to move. The demolding top block 25 pushes down the first side plate 12 and the second side plate 13, so that the formed concrete test block is directly exposed to the air. Then, the top cover 21 and the bottom plate 11 can be removed from the formed concrete test block.
