Description

Technical Field

[0001] This application relates to the field of concrete construction, and in particular to a concrete test block mold that allows for rapid demolding. Background Technology

[0002] Concrete test block molds are standard molds used to make concrete test blocks. Concrete test blocks can be used to test the mechanical properties and durability of concrete. Concrete test block molds are classified by shape as: cube molds, prism molds, cylinder molds, etc. Among them, cube molds are used to make standard cube test blocks to test the compressive strength of concrete and are widely used in construction, road, bridge and other engineering fields.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: When the concrete test mold needs to be demolded, an air pump is generally used to input air into the bottom of the test mold to push the test block out. However, if there is no air pump or other air blowing equipment, the test mold can only be manually inverted and shaken. At this time, the friction between the inner wall of the test mold and the test block is large, and the test block is not easy to move out, making demolding inconvenient. Utility Model Content

[0004] This application provides a concrete test block mold that allows for rapid demolding, solving the problem of inconvenient demolding in the prior art when there is no air blowing equipment. It achieves the effect of rapid demolding by quickly shaking the test block with a rope and opening the side plate.

[0005] This application provides a quick-release concrete test block mold, including a mold body with air holes at the bottom. Side plates are hinged to the sides of the mold body via hinge shafts. Lifting components are provided on the sides of the mold body and the side plates. The lifting components include: four fixing seats located at the middle of three sides of the mold body and the middle of the side plates; a lifting rope located at the bottom of the fixing seats; and a handle located at the bottom end of the lifting rope, wherein the length of the lifting rope is greater than the height of the mold body.

[0006] Furthermore, grooves are provided in the middle of the three sides of the bottom of the test mold body, and the lifting rope is disposed inside the grooves.

[0007] Furthermore, sealing gaskets are embedded on both sides of the inner side of the side plate, and the two sealing gaskets are in contact with the inner wall of the mold body.

[0008] Furthermore, threaded grooves are provided on both sides of the test mold body near the side plate, and threaded rods are threadedly connected inside the threaded grooves, with knobs provided at the outer ends of the threaded rods.

[0009] Furthermore, limit grooves are provided on both sides of the top of the side plate, the limit grooves are matched with the size and position of the threaded grooves, and one end of the threaded rod extends into the interior of the limit grooves.

[0010] Furthermore, each of the four mounting bases has a gripping groove on its bottom side.

[0011] The technical solution provided in this application has at least the following technical effects or advantages:

[0012] The hinged side plates allow one side plate to be opened during demolding, eliminating the friction between the inner side of the test block and the side plate, reducing the resistance during demolding, and allowing external air to enter between the mold body and the test block. When inverted, pulling the three lifting ropes can easily shake the mold body, allowing the test block to easily detach from the mold body during shaking, thus improving demolding efficiency.

[0017] This application discloses a concrete test block mold that can be quickly demolded. A threaded rod 50 rotates within the threaded groove 11 and extends into the limiting groove 21, so that the side plate 20 is installed on the test mold body 10. During demolding, the side plate 20 only needs to be rotated on the test mold body 10 to separate the side plate 20 from one side of the test block, reducing the friction between the test mold body 10 and the outside. In conjunction with the three lifting ropes 43 driving the test mold body 10 to shake when inverted, the test block that is separated from the side plate 20 on one side can be quickly taken out of the test mold body 10, so as to quickly carry out the demolding work.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please refer to Figure 1 and Figure 2This embodiment provides a concrete test block mold that allows for rapid demolding. It includes a mold body 10 with air holes 70 at its bottom. Air is blown into the air holes 70 by an air pump or similar device, causing the test block to separate from the bottom of the mold body 10 and allowing for quick removal. Side plates 20 are hinged to the sides of the mold body 10 via hinge shafts. Lifting components 40 are provided on the sides of the mold body 10 and side plates 20. Sealing gaskets 30 are embedded on both sides of the inner side of the side plates 20, and these gaskets 30 are in contact with the inner wall of the mold body 10. The sealing gaskets 30 on the sides of the side plates 20 connect with the mold body 10. The contact between the inner wall of the mold body 10 and the side plate 20 prevents the concrete inside the mold body 10 from overflowing from the gap between the mold body 10 and the side plate 20, allowing the test block to be formed smoothly. The rotation of the side plate 20 on the mold body 10 allows the test block inside the mold body 10 to be separated from one side plate 20, reducing the friction force on the test block during demolding, making it easy to remove the test block from the mold body 10. One side of the side plate 20 exposes one side of the test block to the air, allowing air to enter between the test block and the inner wall of the mold body 10 from the opening, balancing the air pressure, eliminating the negative pressure adsorption effect, thereby reducing friction and facilitating demolding.

[0020] Please refer to Figure 1 and Figure 2 The lifting assembly 40 includes fixed seats 41, lifting ropes 43, and handles 44. Four fixed seats 41 are located at the center of three sides of the mold body 10 and the center of the side plate 20. Each of the four fixed seats 41 has a grip groove 42 on its bottom side. The lifting rope 43 is located at the bottom of the fixed seats 41, and the handle 44 is located at the bottom end of the lifting rope 43. The length of the lifting rope 43 is greater than the height of the mold body 10. Each of the three bottom sides of the mold body 10 has a groove 45 in its center, and the lifting rope 43 is located inside the groove 45. The inner sides of the groove 45 are rounded to prevent the lifting rope 43 from being pulled too far. 3. Damage occurs when the test mold body 10 is shaken. The four fixed seats 41 extending from the test mold body 10 and the side plate 20 can be conveniently inverted and placed in a triangular shape between the two molds, making it easy for the test block to be demolded from between the two molds when shaken. The grip groove 42 on the fixed seat 41 allows the user to hold the test block in the fixed seat 41 position. When inverted, the three handles 44 cause the lifting rope 43 to press against the groove 45, causing the test mold body 10 to shake from different directions, so that the test block inside the test mold body 10 can be ejected from the bottom. Combined with the separation of the side plate 20 from one side of the test block, demolding is made faster.

[0021] Please refer to Figures 1-3The test mold body 10 has threaded grooves 11 on both sides near the side plate 20. Threaded rods 50 are threaded into the inside of the threaded grooves 11. A knob 60 is provided at the outer end of each threaded rod 50. Limiting grooves 21 are provided on both sides of the top of the side plate 20. The limiting grooves 21 are matched in size and position with the threaded grooves 11, and one end of the threaded rod 50 extends into the limiting groove 21. By rotating the knob 60 at the outer end of the threaded rod 50, the threaded rod 50 can be rotated within the threaded groove 11, causing one end of the threaded rod 50 to extend into the limiting groove 21, thus fixing the test mold body 10 and the side plate 20 together. When the threaded rod 50 is removed from the threaded grooves 11 and the limiting grooves 21, the side plate 20 can be rotated to separate from the test block inside the test mold body 10, allowing for rapid demolding.

[0022] The functional principle of this application can be explained through the following methods:

[0023] In use, rotating knob 60 causes threaded rod 50 to insert into threaded groove 11 and limiting groove 21, fixing the mold body 10 to the side plate 20. Sealing gasket 30 contacts the inner wall of the mold body 10 inside the side plate 20, preventing concrete from overflowing from the gap in the side plate 20. After the specimen is formed, rotating knob 60 moves threaded rod 50 out of threaded groove 11 and limiting groove 21. Rotating side plate 20 separates it from one side of the specimen, allowing external air to enter between the mold body 10 and the specimen through the opening in side plate 20. The air pressure between the test block and the mold body 10 is balanced to reduce the friction force that needs to be overcome when the test block is demolded. The mold body 10 is inverted so that the fixing seats 41 on both sides of the mold body 10 are placed between the two mold bodies 10 on both sides, forming a triangular shape. The three handles 44 at the bottom of the fixing seats 41 are pulled and shaken so that the handles 44 press against the mold body 10 at the groove 45, causing the mold body 10 to shake between the two mold bodies 10. This allows the test block inside the mold body 10 to move down between the two mold bodies 10 at the bottom, completing the rapid demolding of the test block.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.

[0025] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
