Description

Technical Field

[0001] This utility model relates to the field of cement quality testing technology, and in particular to protective sleeves for test molds. Background Technology

[0002] The strength and stiffness of cement concrete after pouring are very important for the construction of buildings, bridges and other projects. Therefore, it is necessary to strictly test the performance of cement concrete to ensure the quality and safety of the building. Usually, cement concrete specimens are made by using molds. The cement concrete is poured into the mold, then vibrated to remove air, and the excess cement concrete on the top layer is scraped off. After hardening, the specimens are demolded.

[0003] In existing technologies, when leveling excess cement concrete in the mold, it is very easy for cement concrete to spill out of the mold. The spilled cement concrete falls on the ground, which not only wastes materials, but also makes it difficult to clean up after it dries, polluting the test environment and increasing the subsequent cleaning costs and workload. Therefore, based on the above situation, it is necessary to design a protective sleeve for the mold to solve the above problems. Utility Model Content

[0004] This utility model provides a protective sleeve for test molds to solve the problem in the prior art where cement concrete spills onto the test molds and falls to the ground, which not only wastes materials but also makes the dried concrete difficult to clean, polluting the test environment and increasing subsequent cleaning costs and workload.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] The test mold protective sleeve includes a main frame and a foldable elastic sleeve. The main frame is used to accommodate the test mold. When the test mold is placed inside the main frame, the outer wall of the test mold fits against the inner wall of the main frame, and the height of the test mold is higher than the height of the main frame. One end of the elastic sleeve is connected to the main frame. The elastic sleeve and the main frame form a collection bin for collecting cement residue. When the elastic sleeve is folded outward, the cement residue in the collection bin can be cleaned.

[0007] Preferably, the top of the main frame is integrally formed with a flow guide, and the cross-section of the flow guide is triangular.

[0008] Preferably, the height of the elastic sleeve is higher than the height of the trial mold.

[0009] Preferably, the cross-section of the collection chamber gradually decreases from top to bottom.

[0010] Preferably, the elastic sleeve has an elastic fold on its side wall. When the elastic sleeve is flipped, the elastic fold opens along with the flipping of the elastic sleeve to increase the opening of the elastic sleeve.

[0011] Preferably, an adjusting plate is slidably connected inside the main frame, and an adjusting screw is rotatably connected to the adjusting plate. One end of the adjusting screw extends to the outside of the main frame and is threadedly connected to the main frame.

[0012] The beneficial effects of this utility model are as follows: by placing the test mold inside the main frame, when cement is poured into the test mold and the cement residue above the main frame is scraped off, all the cement residue will fall into the collection bin. The outward-folding elastic sleeve facilitates the cleaning of the cement residue inside the collection bin, avoiding the waste caused by cement residue spilling out of the test mold and falling to the ground, as well as the problem that the dried cement is not easy to clean.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-5As shown, the protective sleeve for the test mold includes a main frame 1, on which a foldable elastic sleeve 3 is provided. The elastic sleeve 3 and the main frame 1 form a collection bin 4 for collecting cement residue. The main frame 1 is made of a rigid material, such as metal or plastic, which can effectively support the elastic sleeve 3. In use, the main frame 1 is placed on the ground, and the test mold 2 is placed inside. The size of the main frame 1 can be adjusted according to the size and shape of different test molds 2. At this time, the outer wall of the test mold 2 fits against the inner wall of the main frame 1, and the height of the test mold 2 is higher than the height of the main frame 1. Cement is then poured into the test mold 2, and external tools are used to vibrate and vent the cement. During vibration, some cement will splash out and fall into the collection bin 4 for collection. After vibration is complete, the area above the main frame 1 needs to be cleaned. The cement residue is scraped off and then falls into the collection bin 4 for collection. After the cement specimen is made, the mold 2 can be removed from the main frame 1, and another mold 2 waiting to be made can be placed in to make the next specimen. After the specimen is made, the mold 2 on the main frame 1 is removed, and the elastic sleeve 3 is turned outward. The elastic sleeve 3 can be made of rubber, silicone, or other materials, which have a certain strength and sufficient elasticity. The outward turn of the elastic sleeve 3 causes the collection bin 4 to open, exposing all the cement residue inside. The cement residue can then be cleaned off. During this process, due to the obstruction of the main frame 1, the cement residue falls into the collection bin 4, preventing cement from spilling outside the mold 2 and falling to the ground, reducing material waste, and also preventing the cement from drying and hardening on the ground and becoming difficult to clean.

[0022] Reference Figures 1-5 As shown, furthermore, in order to prevent cement residue from accumulating on the main frame 1 when scraped off the mold 2, a guide part 5 is integrally formed and connected to the top of the main frame 1. The cross-section of the guide part 5 is triangular, which can effectively guide the scraped cement residue to a suitable position, keeping the surrounding operating area of ​​the mold 2 relatively clean. At the same time, an adhesive layer, such as Teflon with low surface energy and non-stick properties, can be coated on the surface of the main frame 1, the guide part 5, and the elastic sleeve 3 to reduce the adhesion of cement and facilitate the guidance and cleaning of cement residue.

[0023] In order to effectively allow cement residue to fall into the collection bin 4, the height of the elastic sleeve 3 is higher than the height of the mold 2 when the mold 2 is placed inside the main frame 1. Through the blocking effect of the elastic sleeve 3, it can prevent cement residue from splashing far away and falling to the ground and causing pollution under certain external forces.

[0024] Reference Figure 3As shown, the cross-section of the collection chamber 4 gradually decreases from top to bottom. When cleaning the cement on the elastic sleeve 3, it is folded outwards. The larger upper part can be easily folded over, just like a bag with a large opening, which improves the convenience of operation.

[0025] The elastic sleeve 3 has an elastic folded edge 6 on its side wall. The elastic folded edge 6 can also be made of elastic materials such as rubber or silicone. In actual use, the elastic folded edge 6 can be provided on each side wall. When the elastic sleeve 3 is flipped, the elastic folded edge 6 opens along with the elastic sleeve 3, increasing the opening of the elastic sleeve 3. This ensures that the opening of the elastic sleeve 3 is not too large when it is not flipped, and that the opening can be appropriately enlarged when the elastic sleeve 3 is flipped, thus improving the convenience of flipping the elastic sleeve 3.

[0026] Reference Figure 3 As shown, furthermore, since the thickness of the specimen may vary with the same cement, in order to accommodate specimen molds 2 of different heights, an adjusting plate 7 is slidably connected inside the main frame 1. An adjusting screw 8 is rotatably connected to the adjusting plate 7. One end of the adjusting screw 8 extends to the outside of the main frame 1 and is threadedly connected to the main frame 1. When specimen molds 2 of different heights are placed inside the main frame 1, in order to ensure that the height of the specimen mold 2 is higher than the height of the main frame 1, the adjusting screw 8 is rotated. At this time, the adjusting screw 8 drives the adjusting plate 7 to move up and down in the main frame 1, thereby adjusting the specimen mold 2 to a suitable position and increasing the flexibility of use.
