Description

Technical Field

[0001] The utility model belongs to the technical field of shaping devices, and in particular relates to a manufacturing device capable of preventing ultra-low energy consumption building concrete test blocks from cracking. Background Art

[0002] In civil engineering experiments, standard concrete test blocks are often used to test the strength of concrete. The molding of the test blocks requires concrete test block molds. The most commonly used molds are formed by consolidating a bottom plate and a vertical plate into a whole. Due to the friction between the vertical plate surface and the side of the concrete test block, and the mold as a whole cannot be disassembled, it is difficult to demold the test block after molding. During the solidification process of the concrete test block, hydration reaction usually occurs, which increases the volume of the concrete test block, which will increase the pressure between the concrete test block and the mold. The increase in pressure will increase the friction because pressure is one of the main factors affecting the magnitude of friction. Concrete test blocks with increased friction are more difficult to demold. When making on-site, the concrete test block is usually removed by dropping the mold, but this method can easily cause the concrete test block to hit the ground, causing damage and cracking, and also reduces work efficiency.

[0003] In summary, the existing test blocks have the problems of being difficult to demould and being prone to cracking during demoulding. Utility Model Content

[0004] In view of this, the utility model provides a manufacturing device capable of preventing ultra-low energy consumption building concrete test blocks from cracking, which can solve the problem that the existing test blocks are difficult to demould and are prone to cracking during demoulding.

[0007] The utility model provides a manufacturing device capable of preventing ultra-low energy consumption building concrete test blocks from cracking, and the technical effects are as follows: by setting a mold body, the shape and size of the manufactured concrete test blocks can be standardized and consistent; by setting a demoulding mechanism, the demoulding force can be manually controlled to separate the concrete test block from the mold body, which helps the concrete test block to remain intact during the demoulding process and avoids damage or cracks on the surface of the test block; by setting a fixing mechanism, the position of the demoulding mechanism can be effectively fixed to prevent the demoulding mechanism from moving during the solidification process of the concrete test block, thereby causing cracks in the manufactured concrete test block; by setting a shock-absorbing mechanism, the concrete test block can be prevented from cracking due to expansion due to its own characteristics during solidification, and the vibration when the demoulding mechanism demolds the concrete test block can be reduced, which is beneficial to protecting the integrity of the concrete test block.

[0032] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0033] like Figure 1-6 As shown, it is an embodiment of a manufacturing device provided by the utility model that can prevent ultra-low energy consumption building concrete test blocks from cracking. In this embodiment, it includes a mold body 10, the interior of the mold body 10 is evenly divided into multiple parts, and the mold body 10 is used to make concrete test blocks; wherein, a demoulding mechanism 12 is arranged below the mold body 10, and the demoulding mechanism 12 is used to help the concrete test block to be demoulded, and a fixing mechanism 13 is detachably connected to the demoulding mechanism 12, and the fixing mechanism 13 is rotatably connected to the mold body 10, and the fixing mechanism 13 is used to limit the displacement of the demoulding mechanism 12, and the mold body 10 is fixedly connected to the shock-absorbing mechanism 15, and the shock-absorbing mechanism 15 is used to prevent the concrete test block from cracking.

Concrete is poured inside the mold body 10, and bubbles are eliminated, leveled, and left to stand; during the solidification process, the concrete test block will undergo a hydration reaction, resulting in an increase in volume, and thermal expansion will occur due to the influence of the environment, which increases the difficulty of demoulding and easily forms cracks during the demoulding process.

Four slides 152 are fixedly connected to the third connecting rod 151, one end of the fourth connecting rod 153 is fixedly connected to the mold body 10, and the other end of the fourth connecting rod 153 is fixedly connected to two baffles 154. The two baffles 154 are sleeved on the third connecting rod 151, and the baffle 154 is slidably connected to the third connecting rod 151, and a friction device 155 is arranged between the two baffles 154.

[0038] The surface of the sliding sheet 152 is rough.

A second spring 1552 is arranged between two adjacent movable plates 1551. A groove 1553 is arranged on the movable plate 1551. The groove 1553 is slidably connected to the sliding plate 152.

[0040] The inside of the groove 1553 is a rough surface.

[0041] Furthermore, in the above technical solution, the demolding mechanism 12 includes a first fixed block 121, a support rod 122, a chassis 123, a second through hole 124 and a second fixed block 125, the first fixed block 121 is fixedly connected to one end of the support rod 122, the other end of the support rod 122 is fixedly connected to the chassis 123, a second through hole 124 is provided on the support rod 122, and a second fixed block 125 is fixedly connected above the second through hole 124.

[0042] Furthermore, in the above technical solution, the fixing mechanism 13 includes a pin 131, a first connecting rod 132, a second connecting rod 133, a first spring 134 and an elastic sheet 135. The first connecting rod 132 is rotationally connected to the side wall of the mold body 10 through the pin 131, the first connecting rod 132 is fixedly connected to one end of the first spring 134, the other end of the first spring 134 is fixedly connected to the second connecting rod 133, and the second connecting rod 133 is fixedly connected to the elastic sheet 135.

[0043] Furthermore, in the above technical solution, the second connecting rod 133 is adapted to the second through hole 124 , and the second connecting rod 133 is slidably connected to the second through hole 124 .

[0044] Furthermore, in the above technical solution, the elastic sheet 135 is an acute-angle structure, and the elastic sheet 135 is matched with the second fixing block 125 .

[0045] Furthermore, in the above technical solution, the first fixing block 121 is adapted to the first through hole 11 .

[0046] Furthermore, in the above technical solution, a hole is provided in the middle of the blocking piece 154 , and the size of the hole is larger than the size of the third connecting rod 151 and the sliding piece 152 .

[0047] Specifically, the principle of the utility model is: when in use, the first fixed block 121 is inserted into the first through hole 11 from bottom to top, so that the upper top surface of the first fixed block 121 is flush with the lower bottom surface of the mold body 10, the mold body 10 is slidably connected with the first fixed block 121, the first connecting rod 132 is rotated so that the second connecting rod 133 and the elastic sheet 135 are inserted into the second through hole 124, and can slide inside the second through hole 124, drag the elastic sheet 135, the first spring 134 is extended, and the elastic sheet 135 is hooked on the second fixed block 125 to complete the displacement restriction of the demoulding mechanism 12. Concrete is poured into the mold body 10, and bubbles are eliminated, leveled, and left to stand; during the solidification process, the concrete test block will undergo a hydration reaction to increase its volume, and thermal expansion will occur due to the influence of the environment, which increases the difficulty of demoulding and easily forms cracks during the demoulding process.

[0048] When demoulding, the elastic sheet 135 is pinched to separate the elastic sheet 135 from the second fixed block 125, and the second connecting rod 133 is slid out of the second through hole 124 to unlock the demoulding mechanism 12, and the whole device is lifted, shaken up and down and bumped up and down on the ground. Due to the influence of inertia and gravity, the first fixed block 121 will move upward to lift the concrete test block from the mold body 10. In the process of shaking and bumping, the chassis 123 is constantly in contact with the ground and will vibrate. The vibration force is transmitted to the baffle 154 through the slide 152. The baffle 154 has a tendency to move, and the baffle 154 drives the friction device 155 to move. Due to the structure of the third connecting rod 151 being narrow in the middle and wide on both sides, the friction force of the friction device 155 moving to any side will increase. When the friction device 155 moves, the moving sheet 1551 slides on the slide 152, and the second spring 1552 is stretched.
