Description

Technical Field

[0001] This disclosure relates to the field of building material testing equipment technology, and more specifically, to a protective cover for a cement mortar compaction table that can prevent cement contamination. Background Technology

[0002] In the field of building materials testing, cement mortar vibration tables are crucial equipment for molding cement mortar test blocks. During actual testing, the mold must be firmly placed on the table surface, and the high-frequency vibration of the equipment promotes the compaction of the mortar. However, during vibration, mortar particles easily splash from the edges of the mold, scattering onto the surface of the vibration table, gaps, and the surrounding environment, leading to a series of problems: Equipment contamination: Once mortar adheres to the metal surface of the vibration table, it is extremely difficult to clean after hardening. Long-term accumulation not only affects the cleanliness of the equipment but also negatively impacts its accuracy, even accelerating aging and shortening its lifespan. Environmental mess: Splashed cement mortar contaminates laboratory surfaces and floors, disrupting the cleanliness of the laboratory, reducing testing efficiency, and significantly increasing cleaning costs. Insufficient protection: Existing protective measures, such as protective covers, are generally prone to damage and have poor sealing. Moreover, after covering the vibration table, these covers prevent operators from directly observing the state of the mold, causing inconvenience to the testing work and affecting the accuracy and reliability of the test results.

[0003] In summary, existing cement mortar vibration tables have significant shortcomings in terms of pollution prevention, and there is an urgent need for an efficient and practical pollution prevention and protection device to solve the above problems.

[0031] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0032] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0033] In related technologies, during the use of cement mortar vibratory compaction tables, mortar particles are prone to splashing out from the edges of the mold and scattering onto the surface, gaps, and surrounding environment of the compaction table, leading to a series of problems. For example, it can cause equipment contamination and create a dirty and messy working environment.

[0034] Based on this, this disclosure provides a protective cover 2 for a cement mortar compaction table that can prevent cement contamination. Two embodiments of the protective cover 2 are provided below.

[0035] Example 1:

[0036] See Figure 1 , Figure 2 as well as Figure 3 The cement mortar vibrating table has a test mold 1 and a protective cover 2 for protecting the test mold 1. The protective cover 2 includes a base plate 21 and a plurality of baffles 22 arranged around the base plate 21. The base plate 21 and the plurality of baffles 22 form a protective space 222 for the test mold 1.

[0037] In this embodiment, when preparing the cement adhesive, the mold 1 is first sealed with a protective cover 2. This effectively intercepts cement mortar splashed during compaction, significantly reducing the contamination of the compaction table surface, crevices, and surrounding environment by the mortar, thus significantly improving the contamination control rate. Simultaneously, due to the highly efficient anti-fouling performance of the protective cover 2, the amount of harmful cleaning agents used to clean stubborn mortar contamination can be reduced, lowering environmental pollution and reducing the risk of operators coming into contact with harmful cleaning agents, making it safer and more environmentally friendly.

[0038] As an example, the protective cover 2 can be 20.2 cm long, 18.6 cm wide, and 2 cm high. It should be noted that in other embodiments, the parameters of the protective cover 2 are not limited to these, and will not be elaborated upon here.

[0039] In some embodiments of this disclosure, see Figure 3Along the first direction of the mold 1, protrusions 11 are symmetrically arranged on both sides of the mold 1. The protective cover 2 is in an installed state, where the protrusions 11 contact the baffle 22, and the remaining portion of the mold 1 on the side with the protrusions 11 forms a buffer space 111 with the baffle 22. In this embodiment, the protrusions 11 can increase the connection strength between the protective cover 2 and the mold 1 to a certain extent, preventing the protective cover 2 from falling off due to vibration during use on the cement mortar vibrating table. Simultaneously, the buffer space 111 formed by the remaining portion of the mold 1 on the side with the protrusions 11 and the baffle 22 further buffers the vibration from the mold 1 to the protective cover 2, thereby strengthening the connection strength between the protective cover 2 and the mold 1.

[0040] Furthermore, in this embodiment, the protective cover 2 has good temperature resistance. For example, the protective cover 2 can adapt to an ambient temperature range of -20℃ to 80℃. Within this temperature range, the protective cover 2 will not deform or crack, ensuring normal use under different ambient temperatures.

[0041] In some embodiments of this disclosure, the protective cover 2 is made of an elastic material. By making the protective cover 2 an elastic material, on the one hand, the protective cover 2 can completely wrap the mold 1, improving the degree of protection for the mold 1; on the other hand, the protective cover 2 can be applied to cement mortar molding molds 1 with different types of frames, greatly improving the versatility and adaptability of the protective cover 2.

[0042] As an example, the protective cover 2 is a one-piece molded design. This makes the protective cover 2 easy to manufacture, and the one-piece molded design also makes it easy to store.

[0043] In some embodiments of this disclosure, the protective cover 2 includes a layered antistatic coating 23 and a transparent wear-resistant layer 24. The protective cover 2 is in an installed state, in which the antistatic coating 23 is positioned close to the test mold 1. In this embodiment, the side of the protective cover 2 closest to the test mold 1 is the antistatic coating 23, which reduces the adsorption of mortar particles onto the protective film due to static electricity, facilitating cleaning. Simultaneously, the transparent wear-resistant layer 24 is provided on the other side, providing the protective cover 2 with good wear resistance and transparency, effectively resisting friction from mortar particles without affecting the operator's observation of the test mold 1.

[0044] As an example, the transparent abrasion-resistant layer 24 can be a transparent silicone layer. In actual production, the transparent silicone layer of the protective cover 2 must pass 100 abrasion tests. After the test, the surface must not be damaged to ensure that it can effectively resist the friction of abrasive particles and maintain good physical properties during multiple uses before it can be used to design the protective cover 2.

[0045] Furthermore, the transparent silicone layer used in this embodiment has good durability and can be reused more than 500 times. Compared with disposable plastic film, it can save more than 90% of the consumable cost, bringing significant economic benefits to the laboratory for long-term use.

[0046] In some embodiments of this disclosure, the thickness of the protective cover 2 is between 4 and 6 cm. For example, the thickness of the protective cover 2 can be 4 cm, 5 cm, or 6 cm. It should be noted that in other embodiments, the thickness of the protective cover 2 is not limited to this, and this application will not elaborate on this.

[0047] In some embodiments of this disclosure, when the vibration frequency of the cement mortar vibratory table is 60 times / min, the vibration deviation of the protective cover 2 is less than 2%. This ensures that the protective cover 2 will not significantly affect the vibration parameters of the vibratory table during vibration, thereby ensuring test accuracy.

[0048] Finally, the usage of the protective cover 2 is explained in detail: When installing the protective cover 2 onto the mold 1, first open the protective cover of the cement mortar vibrating table, and cover the mold 1 in the working area of ​​the vibrating table with the protective cover 2. Carefully align the edges of the protective cover 2 and the vibrating table to ensure that the protective cover 2 completely covers the mold 1. After installation, start the cement mortar vibrating table to perform a cement mortar block molding test. After the test, lift the protective cover 2 upwards and remove it from the cement mortar vibrating table. After removal, rinse and clean the protective cover 2, let it dry, and reuse it.

[0049] Example 2:

[0050] See Figure 4 , Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the substrate 21 and the baffle 22 are detachably connected, and the size of the protective space 222 formed by the substrate 21 and the baffle 22 is variable.

[0051] It is understandable that different cement mortar vibrating tables have different specifications of test molds 1. However, for the protective cover 2, if the specifications of the test molds 1 vary greatly, the existing protective cover 2 is difficult to cover them. The protective cover 2 provided in this embodiment has a base plate 21 and a baffle 22 that are detachably connected. It can be flexibly combined according to the specifications of the test molds 1 to meet the needs of test molds 1 of various cement mortar vibrating tables, thereby improving the applicability of the protective cover 2.

[0052] In some embodiments of this disclosure, the substrate 21 has a first mounting groove group 211 symmetrically arranged along its width direction 3 and a second mounting groove group 212 symmetrically arranged along its length direction 4; the first mounting groove group 211 includes a plurality of first mounting sub-grooves 2111 arranged along the length direction 4 of the substrate 21; the second mounting groove group 212 includes a plurality of second mounting sub-grooves 2121 arranged along the width direction 3 of the substrate 21; a portion of the baffle 22 is disposed in the first mounting sub-grooves 2111 and is interference-fitted with the sidewall of the first mounting sub-grooves 2111; the remaining portion of the baffle 22 is disposed in the second mounting sub-grooves 2121 and is interference-fitted with the sidewall of the second mounting sub-grooves; wherein, along the length direction of the baffle 22, the baffle 22 has a plurality of insertion slots 221.

[0053] As an example, the first mounting slot group 211 may include three first mounting sub-slots 2111. It should be noted that in other embodiments, the number of first mounting sub-slots 2111 in the first mounting slot group 211 may not be limited to three, and this disclosure will not elaborate on this.

[0054] As another example, the second mounting slot group 212 may include three second mounting sub-slots 2121. It should be noted that in other embodiments, the number of second mounting sub-slots 2121 in the second mounting slot group 212 may not be limited to three, and this disclosure will not elaborate on this.

[0055] Specifically, when changing the size of the protective space 222 of the protective cover 2, a portion of the baffles 22 can be inserted into the first mounting sub-slots 2111 on the substrate 21, and a portion of the baffles 22 can be inserted into the second mounting sub-slots 2121 on the substrate 21. Then, the remaining baffles 22 are inserted onto the baffles 22 already inserted into the first mounting sub-slots 2111 and the second mounting sub-slots 2121. The multiple baffles 22 and the substrate 21 together form the protective space 222. If it is necessary to adjust the size of the protective space 222, the baffles 22 can be adjusted within different first mounting sub-slots 2111 corresponding to the first mounting slot group 211 and within different second mounting sub-slots 2121 corresponding to the second mounting slot group 212.

[0056] Furthermore, to enhance the connection strength between the baffle 22 and the second mounting sub-slot 2121, a protrusion 223 is provided on the baffle 22. When the baffle 22 is inserted into the first mounting sub-slot 2111, the protrusion 223 is interference-fitted with the side wall of the first mounting sub-slot 2111; when the baffle 22 is inserted into the second mounting sub-slot 2121, the protrusion 223 is interference-fitted with the side wall of the second mounting sub-slot 2121.

[0057] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
