Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a composite trench cover assembly for convention centers. Background Technology

[0002] Currently, the construction and development of convention and exhibition centers are progressing rapidly, and their functions are becoming increasingly diversified. In the infrastructure construction of convention and exhibition centers, the installation of composite trenches is crucial. It provides a channel for cable laying, ensures the normal operation of various electrical equipment in the convention and exhibition center, and is of great significance for the smooth conduct of convention and exhibition activities. After the cable laying is completed, the composite trenches need to be covered with covers to protect the cables and ensure the safety of personnel and equipment. With the continuous development of the convention and exhibition industry, higher requirements are being placed on the performance and quality of composite trench covers.

[0003] Prior to this technical solution, concrete trench covers were commonly used to address the issue of composite trench covers for convention centers. In practical applications, when laying composite trenches, construction workers would select appropriately sized concrete trench covers, transport them to the top of the trench using hoisting equipment, and then install them. During installation, it was crucial to ensure the cover's accurate positioning to guarantee its stability. When cable repairs or replacements were needed, the cover had to be lifted again using hoisting equipment, and then reinstalled after the repairs were completed.

[0004] However, existing concrete trench covers have significant drawbacks. Their bulky size makes transportation, installation, and maintenance extremely inconvenient. The weight of the covers also increases the risk of injury to workers during operation, posing a significant safety hazard. Furthermore, this construction method is labor-intensive and time-consuming, resulting in a waste of resources and failing to meet national requirements for high efficiency, energy conservation, and environmental protection. Utility Model Content

[0005] This application provides a composite trench cover assembly for convention centers, which uses a fiberglass cover and gasket combination to reduce the weight of the cover and improve the buffering effect.

[0006] This application provides a composite trench cover assembly for convention centers, which adopts the following technical solution: A composite trench cover assembly for an exhibition center includes a cover body with several reinforcing ribs along its length at the bottom. A gasket is provided on one side of the cover body. Both the cover body and the gasket are made of fiberglass material. The gasket has a snap-fit ​​groove that mates with the reinforcing ribs.

[0007] By adopting the above technical solution, the present invention provides a composite trench cover assembly for convention centers. In use, the cover body and the gasket are fixed together by interlocking grooves. The cover body and gasket are made of fiberglass material, which reduces the weight of the cover, facilitates transportation, installation and maintenance, reduces manpower and material consumption, and meets the national requirements for high efficiency, energy saving and environmental protection. The interlocking grooves on the gasket that cooperate with the reinforcing ribs can better connect the gasket and the cover body, and the gasket can play a shock absorption and buffering role.

[0008] Preferably, the cross-section of the reinforcing rib is T-shaped, and the inner wall shape of the snap-fit ​​groove is adapted to the T-shaped cross-section.

[0009] By adopting the above technical solution, the T-shaped cross-section of the reinforcing rib can improve the overall structural strength of the cover plate during use. The shape of the inner wall of the snap-fit ​​groove is adapted to the T-shaped cross-section, which can make the gasket and the reinforcing rib fit better, thereby making the gasket and the cover plate body tightly connected.

[0010] Preferably, the bottom of the pad is provided with a plurality of anti-slip protrusions, which are evenly distributed on the bottom surface of the pad.

[0011] By adopting the above technical solution, multiple anti-slip protrusions are evenly distributed on the bottom of the gasket during use, which can enhance the friction between the cover plate assembly and the composite groove, making the cover plate assembly more stable when placed on the composite groove.

[0012] Preferably, one side of the cover plate body is provided with a positioning groove, and the other side is provided with a positioning block that cooperates with the positioning groove. When the cover plate body is laid, adjacent cover plates overlap each other through the positioning groove and the positioning block.

[0013] By adopting the above technical solution, during use, the positioning groove and positioning block are used to make adjacent cover plates overlap each other, which enhances the connection stability between cover plates, avoids misalignment and separation of cover plates after laying, and improves the accuracy and efficiency of the overall laying.

[0014] Preferably, the opening width of the snap-fit ​​groove is smaller than the bottom width of the reinforcing rib, so as to restrict the movement of the reinforcing rib.

[0015] By adopting the above technical solution, during use, the gasket has a snap-fit ​​groove that matches the reinforcing rib, which can be used to connect the two. The opening width of the snap-fit ​​groove is smaller than the bottom width of the reinforcing rib, which can restrict the movement of the reinforcing rib and ensure the stability and reliability of the cover plate assembly structure.

[0016] Preferably, the top of the gasket is provided with an arc-shaped groove, and a cavity is provided between the arc-shaped groove and the cover plate body.

[0017] By adopting the above technical solution, the cavity between the arc groove and the cover plate body can further enhance the shock absorption and buffering performance of the gasket during use, effectively protecting the cover plate body and the composite trench.

[0018] Preferably, the width of the cover plate body is much larger than the width of the gasket, and multiple gaskets are respectively installed at the bottom of the cover plate body.

[0019] By adopting the above technical solution, multiple gaskets with a width smaller than the cover plate body are installed at the bottom of the cover plate body during use. While ensuring that the gaskets play a role in shock absorption and buffering, the gaskets can be arranged more flexibly according to actual installation needs, making reasonable use of materials and reducing unnecessary material usage.

[0020] Preferably, a wear-resistant layer is provided at the contact surface between the snap-fit ​​groove of the gasket and the reinforcing rib.

[0021] By adopting the above technical solution, when using the gasket, a wear-resistant layer is set at the contact surface between the snap-fit ​​groove and the reinforcing rib, which can reduce the wear when the snap-fit ​​groove and the reinforcing rib come into contact, and extend its service life.

[0022] In summary, this application has the following beneficial effects: 1. The present invention relates to a composite trench cover assembly for an exhibition center, wherein the cover body is provided with several reinforcing ribs along the length of the bottom, which are reinforced and have a T-shaped cross-section, thereby improving the overall structural strength of the cover. 2. The present invention relates to a composite trench cover assembly for an exhibition center, wherein both the cover body and the gasket are made of fiberglass material, which reduces the weight of the cover and makes transportation, installation and maintenance more convenient; 3. The present invention provides a composite trench cover assembly for an exhibition center. The cover body has gaskets on both sides, which cooperate with the reinforcing ribs and have anti-slip protrusions at the bottom. After installation, the gaskets are located on both sides of the composite trench, which can play a role in shock absorption, buffering and anti-slip. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] This utility model discloses a composite trench cover assembly for convention centers, such as... Figure 1 and Figure 2 As shown, the cover plate includes a cover plate body 1 and a gasket 3. The gasket 3 is installed on both sides of the cover plate body 1, and the snap-fit ​​groove 4 on the gasket 3 cooperates with the reinforcing rib 2 at the bottom of the cover plate body 1. This achieves the effect of reducing the weight of the cover plate assembly, improving the overall structural strength and buffering effect. This is because the fiberglass material is lightweight, the reinforcing rib 2 can enhance the structural strength, and the gasket 3 can play a buffering role.

[0026] Specifically, the cover plate body 1 includes structures such as reinforcing ribs 2. The reinforcing ribs 2 are arranged along the length of the bottom of the cover plate body 1, and their cross-section is T-shaped. This T-shaped cross-section increases the contact area between the reinforcing ribs 2 and the cover plate body 1, better dispersing stress and enhancing the overall structural strength of the cover plate body 1. The reinforcing ribs 2 can be solid or hollow to further reduce weight. In terms of materials, in addition to fiberglass, carbon fiber composite materials can also be used, provided the strength requirements are met. The reinforcing ribs 2 and the cover plate body 1 can be integrally molded, using processes such as injection molding to ensure a tight bond between the two, guaranteeing the stability and integrity of the structure.

[0027] Specifically, the gasket 3 includes a snap-fit ​​groove 4, anti-slip protrusions 5, and an arc-shaped groove 8. The snap-fit ​​groove 4 is formed on the gasket 3, and its inner wall shape matches the T-shaped cross-section of the reinforcing rib 2. The opening width of the snap-fit ​​groove 4 is smaller than the bottom width of the reinforcing rib 2, which restricts the movement of the reinforcing rib 2 and ensures a firm connection between the gasket 3 and the cover plate body 1. A wear-resistant layer, such as a rubber wear-resistant layer or a ceramic wear-resistant layer, is provided at the contact surface between the snap-fit ​​groove 4 and the reinforcing rib 2 to reduce wear between the reinforcing rib 2 and the snap-fit ​​groove 4 and extend its service life. The anti-slip protrusions 5 are located at the bottom of the gasket 3, with multiple anti-slip protrusions 5 evenly distributed on the bottom surface of the gasket 3. The anti-slip protrusions 5 can be hemispherical, conical, or other shapes, which increase the friction between the gasket 3 and the sides of the composite groove, preventing the cover plate assembly from sliding. An arc-shaped groove 8 is located on the top of the gasket 3, and a cavity is formed between the arc-shaped groove 8 and the cover plate body 1. This cavity serves as a buffer and shock absorber, absorbing some energy when external force is applied to the cover plate body 1. The width of the gasket 3 is much smaller than the width of the cover plate body 1, and multiple gaskets 3 are installed on both sides of the bottom of the cover plate body 1. The gasket 3 can be installed on the cover plate body 1 through the engagement of the snap-fit ​​groove 4 and the reinforcing rib 2. This installation method is simple and convenient, facilitating construction and maintenance.

[0028] The combination logic of these structures is as follows: the reinforcing rib 2 enhances the structural strength of the cover plate body 1, enabling it to withstand greater pressure and external forces; the gasket 3 is installed on both sides of the cover plate body 1 through the snap-fit ​​groove 4 in conjunction with the reinforcing rib 2; the anti-slip protrusions 5 ensure the stability of the cover plate assembly after installation; and the arc-shaped groove 8 and the cavity provide cushioning and shock absorption functions. This combination method allows the cover plate assembly to have sufficient strength, reduce weight, and improve cushioning performance, making it suitable for the use of composite trenches in exhibition centers.

[0029] The implementation principle of this embodiment is as follows: The composite trench cover assembly for the convention center in this embodiment uses fiberglass material, which significantly reduces weight compared to traditional concrete trench covers, facilitating transportation, installation, and maintenance. This reduces the labor intensity of construction workers and minimizes waste of manpower and resources, meeting national requirements for high efficiency, energy conservation, and environmental protection. The addition of reinforcing ribs 2 and gaskets 3 further optimizes the performance of the cover assembly. Reinforcing ribs 2 enhance structural strength, while gaskets 3 improve cushioning and anti-slip capabilities, thereby improving the practicality and safety of the cover assembly and representing a significant improvement and contribution to existing technologies.

[0030] Example 2 The difference between this embodiment and the previous embodiment is that the engagement of the gasket 3's snap-fit ​​groove 4 and the reinforcing rib 2 can be achieved through magnetic adsorption. A magnetic material is provided inside the snap-fit ​​groove 4 of the gasket 3, and the reinforcing rib 2 is made of a magnetically adsorbable metal material or has an adsorbable coating on its surface. This method also achieves the connection between the gasket 3 and the cover plate body 1, and makes installation and disassembly more convenient and quick.

[0031] The implementation principle of this embodiment is as follows: by using magnetic adsorption, the connection between the gasket 3 and the cover plate body 1 is ensured to be stable, while improving the efficiency of installation and disassembly and reducing construction time and difficulty. When it is necessary to repair or replace the cover plate assembly, the gasket 3 and the cover plate body 1 can be separated more easily, which has better flexibility and practicality, and effectively improves and optimizes the installation method of the prior art.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
