Description

Technical Field

[0001] This application relates to the technical field of cable trenches, and in particular to an indoor cable trench structure. Background Technology

[0002] Various problems may arise during the construction of cable trenches penetrating walls, requiring comprehensive consideration of design, construction, environmental factors, and subsequent maintenance. For example, waterproofing and sealing are crucial: if the opening in the wall is not properly sealed, rainwater, groundwater, or humid gases may seep in, causing cable insulation aging or electrical short circuits. Fire safety is another issue: cables passing through walls may damage existing fire compartments, allowing fire or smoke to spread through the openings during a fire. Designing a cable trench structure that effectively prevents fire, provides waterproofing, and achieves socio-economic benefits presents certain difficulties and shortcomings in actual production. Utility Model Content

[0003] In order to overcome the shortcomings of related technologies, this application provides an indoor cable trench structure.

[0004] An indoor cable trench structure includes a cable trench body, cable trench supports, cables, galvanized angle steel, and fireproof boards. The galvanized angle steel is installed on the trench wall at the location where wall penetrations are sealed, and the galvanized angle steel and the fireproof boards on both sides of the wall cooperate to seal the trench. The fireproof boards have multiple cable holes. Fireproof bags are also installed between the fireproof boards to seal them. The fireproof boards, fireproof bags, and galvanized angle steel work together to form a fire barrier. The cable holes through the fireproof boards are sealed tightly with organic sealant. The cables on both sides of the fire barrier are tightly separated and wrapped with organic sealant, the thickness of which is greater than the surface thickness of the fire barrier, and the thickness of the organic sealant protruding from the fireproof board surface is not less than 10mm. The cables on the outside of the fireproof boards are coated with fire-retardant paint. The cable trench body is equipped with multiple cable trench supports.

[0005] Furthermore, multiple grouting devices are installed on the fireproof boards on both sides of the fire barrier. The grouting devices include extension pipes, grouting pipes, and sealing pipes, which are arranged sequentially outward from the fireproof board. The grouting pipes are provided with grouting holes. The diameter of the sealing pipe at the end closest to the fireproof board is larger than the diameter at the end furthest from the fireproof board. The end of the sealing pipe closest to the fireproof board is matched with the grouting pipe. The diameter of the threaded sealing pipe at the end furthest from the fireproof board is matched with the diameter of the cable coated with fire-retardant paint.

[0006] Furthermore, the sealing tube is provided with a detachable opening.

[0007] Furthermore, the sealing tube is configured as a plastic sealing tube.

[0008] Furthermore, the fireproof board is configured to be a 12mm thick fireproof board.

[0009] Furthermore, the width between the fireproof boards on both sides of the fire barrier is set at 250mm to accommodate fireproof bags.

[0010] Furthermore, the cables on the outside of the fireproof board are coated with fire-retardant paint with a thickness of 1 mm.

[0011] Furthermore, the sealing tube is configured as a threaded sealing tube.

[0012] Furthermore, the organic sealant on both sides of the fire barrier is set to be 20mm thicker than the surface layer of the fire barrier.

[0013] Furthermore, the cable trench cover is made of transparent acrylic glass.

[0014] This application has at least one of the following beneficial effects:

[0015] 1. This application provides an indoor cable trench structure that integrates a design that is both fireproof and waterproof, and also has socio-economic benefits.

[0016] 2. Grouting devices can reinforce cable trench structures: filling voids or cracks within the walls, restoring their integrity and strength, and filling gaps. They also provide waterproofing, sealing, and leak prevention. The installation of grouting devices and grouting holes allows for route planning and grout delivery of the injected organic sealant, facilitating grouting and improving the stability, durability, and safety of the cable trench structure.

[0017] 3. In the embodiments of this application, the cable trench support is a key component of the cable laying system. Its main function is to provide support, fixation and orderly arrangement for the cables, so as to ensure the safe, stable and long-term reliable operation of the cables.

[0018] 4. The installation of a brick-concrete surface in the cable trench serves to balance structural protection, safety, and ease of maintenance. The brick-concrete surface increases the structural stability of the cable trench, preventing wall collapse: it allows the trench bottom to effectively resist soil pressure, avoiding soil slippage or collapse, especially in areas with soft soil or high groundwater levels. Furthermore, the brick-concrete surface ensures even load distribution: it disperses the weight of the cables and overlays, reducing the risk of cable compression due to uneven foundation settlement.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] Example 1:

[0025] Reference Figure 1 and Figure 2 An indoor cable trench structure includes a cable trench body, a cable trench support 8, cables 1, galvanized angle steel 9, and fireproof boards 5. Four galvanized angle steels 9 are erected on the trench wall at the sealing section and fixed with expansion bolts 10. The galvanized angle steels 9 and the 12mm thick fireproof boards 5 on both sides of the wall 7 cooperate to seal the trench. The fireproof boards 5 are provided with multiple cable holes 12 for the cables 1 to pass through. In this embodiment, each fireproof board 5 is provided with six square cable holes 12. Three cables 1 pass through each cable hole 12. Fireproof bags 4 are also provided between the fireproof boards 5 for sealing, with a sealing thickness of 250mm. Fireproof board 5, fireproof bag 4, and galvanized angle steel 9 work together to form a fire barrier. The cable hole 12 through which cable 1 passes in the fireproof board 5 is sealed tightly with organic sealant 3. The area around cable 1 on both sides of the fire barrier is also tightly sealed with organic sealant 3, with the thickness of the organic sealant 3 on both sides exceeding the surface thickness of the fire barrier. The area around cable 1 on the outer side and the gaps in the fireproof board 5 are sealed with organic sealant 3 in a geometric pattern, with the thickness of the organic sealant 3 protruding at least 10mm from the surface of the fireproof board 5, and the surface is smooth. In this embodiment, the thickness of the organic sealant 3 on both sides of the fire barrier is set to 20mm greater than the surface thickness of the fire barrier. Cable 1 on the outer side of the fireproof board 5 is coated with fire-retardant paint 2, with a coating thickness of 1mm. Holes within the wall are sealed with fireproof bag 4, fireproof board 5, or organic sealant 3 to meet fire resistance time requirements.

[0026] The cable trench itself is equipped with multiple cable trench supports 8. The cable trench supports 8 are a key component of the cable 1 laying system, their main function being to provide support, fixation, and orderly arrangement for the cables 1, ensuring the safe, stable, and long-term reliable operation of the cables 1. On one hand, the cable trench supports 8 support and fix the cables 1, bearing their weight: the supports bear the vertical load of the cables 1, preventing them from sagging or deforming due to their own weight. On the other hand, the cable trench supports 8 prevent the cables 1 from being suspended or dragging on the ground: maintaining the distance between the cables 1 and the trench bottom, preventing water immersion, mechanical damage, or small animal gnawing. The cable trench supports 8 resist external forces: in the event of vibration, earthquake, or soil displacement, the cable trench supports 8 can reduce the risk of cable 1 displacement. They also ensure safe spacing. Multiple cable trench supports 8 can separate the cables 1: preventing overheating or short circuits between cables 1 and preventing electromagnetic interference. The cable trench supports 8 facilitate heat dissipation of the cables 1, preventing a decrease in current carrying capacity.

[0027] A brick-concrete surface 11 is installed at the bottom between the two fireproof boards 5. The brick-concrete surface 11 in the cable trench primarily serves to balance structural protection, safety, and ease of maintenance. The brick-concrete surface 11 increases the structural stability of the cable trench, preventing trench wall collapse: it effectively resists soil pressure, preventing soil slippage or collapse, especially in areas with soft soil or high groundwater levels. The brick-concrete surface 11 also distributes load evenly: it disperses the weight of the cable 1 and the overlay layer, reducing the risk of uneven foundation settlement compressing the cable 1. The brick-concrete surface 11 provides mechanical protection, resisting external pressure: it withstands the static load of construction machinery, preventing damage to the cable 1. The brick-concrete surface 11 also provides waterproofing and moisture resistance, blocking groundwater penetration: it reduces moisture seepage into the trench, lowering the risk of moisture damage and insulation aging of the cable 1. The brick-concrete surface 11 provides fireproof sealing assistance: the brick-concrete surface 11 provides a fixed base for the fireproof package 4 and fireproof board 5 at the point where the cable 1 passes through the wall, enhancing the sealing performance.

[0028] The cover plate at the point where the indoor cable trench structure is close to the fireproof sealing facility through the wall should be made of transparent plexiglass so that inspection personnel can check the sealing status.

[0029] Example 2:

[0030] Reference Figure 3The difference between this embodiment and Embodiment 1 is that: multiple grouting devices are provided on the fireproof boards 5 on both sides of the fire barrier. The grouting devices include an extension pipe 18, a grouting pipe 17, and a sealing pipe 13, which are arranged sequentially outward along the fireproof board 5; one end of the extension pipe 18 is fixedly connected to the fireproof board 5, and the other end of the extension pipe 18 is fixedly connected to the grouting pipe 17. The extension pipe 18 is used to fill the organic sealant 3 on both sides of the fire barrier where the thickness exceeds the thickness of the surface layer of the fire barrier; the grouting pipe 17 is provided with grouting holes 14 for injecting the organic sealant 3; the diameter of the sealing pipe 13 near the fireproof board 5 is larger than the diameter of the section away from the fireproof board 5, the end of the sealing pipe 13 near the fireproof board 5 is matched with the grouting pipe 17, and the diameter of the threaded sealing pipe 13 away from the fireproof board 5 is matched with the diameter of the cable 1 coated with fire-retardant paint 2.

[0031] The sealing tube 13 is provided with a detachable opening 15, which allows the sealing tube 13 to be pried open and directly removed for easy replacement and maintenance. The sealing tube 13 is made of plastic, making it lightweight.

[0032] In another embodiment, the sealing tube 13 can also be configured as a threaded sealing tube 13, with the sealing tube 13 and the grouting tube 17 being threadedly connected.

[0033] The grouting device can reinforce the cable trench structure by filling voids or cracks in the wall 7, restoring its integrity and strength, and filling gaps. It also serves to waterproof, seal, and prevent leaks. The grouting device and grouting holes 14 facilitate the routing and delivery of the injected organic sealant 3, improving the stability, durability, and safety of the cable trench structure.

[0034] In summary, this application provides a novel indoor cable trench structure that integrates fireproof and waterproof design, while also providing socio-economic benefits and preventing the intrusion of small animals or foreign objects.

[0035] 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.
