Description

Technical Field

[0001] This application relates to the field of cable tray wall-through technology, and in particular to a fireproof cable tray wall-through structure. Background Technology

[0002] Fire-resistant cable trays are cable support devices specifically designed to maintain the integrity of cable lines and delay the spread of fire in fire environments. They provide external fire protection for cables through the combined action of fire-resistant coatings and sealing processes.

[0003] In traditional fireproof cable tray installation, the holes through which the fireproof cable tray passes in the wall need to be sealed with fireproof adhesive, fireproof cotton and other sealing materials, together with fireproof boards, to prevent the fire from spreading through the holes in the event of a fire.

[0004] The above-mentioned structure has the following shortcomings after application: Over time, due to environmental factors, the fireproof structure will crack, corrode, and deform, resulting in a significant reduction in fireproof performance, thus requiring maintenance; Furthermore, the fireproof board is "U" shaped, which does not have much impact on the initial construction of cable trays and cables, but during later maintenance, since the cable trays are already in place, it is necessary to disconnect the cable trays and cables and then reconstruct them, making maintenance relatively inconvenient. Therefore, this application proposes a new technical solution. Utility Model Content

[0005] To facilitate the inspection or disassembly of fire-resistant structures, this application provides a fire-resistant cable tray through-wall structure.

[0006] This application provides a fireproof cable tray wall-mounted structure, which adopts the following technical solution:

[0007] A fireproof cable tray through-wall structure includes a fireproof cable tray and a fixing mechanism sleeved on the fireproof cable tray. The fixing mechanism includes two sets of fixing components, one set of fixing components is set on one side of the wall, and the other set of fixing components is set on the other side of the wall. Each fixing component includes a fireproof plate one and a fireproof plate two. The fireproof plate one and the fireproof plate two correspond one-to-one and are spliced ​​together to be sleeved on the fireproof cable tray. After the fireproof plate one and the fireproof plate two are spliced ​​together, they abut against the wall surface and are sealed and fixed by fireproof adhesive.

[0008] Fireproof board one and fireproof board two are snapped together and fixed. Fireproof board one abuts against the side wall of fireproof board two and has a T-shaped groove with one end open along the length of the groove. Fireproof board two is provided with a snap-fit ​​block that slides and connects to the groove. The snap-fit ​​block has a T-shaped cross section.

[0009] Optionally, the fireproof board one and fireproof board two are provided with locking components. The locking components include fixing holes and limiting rods. The fixing holes are respectively opened in fireproof board one and fireproof board two and allow the limiting rod to pass through vertically. After the fireproof board one and fireproof board two are spliced, the two fixing holes are coaxial. The diameter of the limiting rod is smaller than that of the fixing hole, and multiple wedge-shaped blocks extend from the outer wall of the limiting rod. Both fireproof board one and fireproof board two are provided with limiting components for limiting the limiting rod within the fixing holes.

[0010] Optionally, the fixing assembly further includes an abutment block slidably connected to the side wall of the fireproof cable tray. The abutment block is connected to an adjusting strip for pressing the fireproof board 1 and fireproof board 2 located on both sides of the wall against the wall surface. The adjusting strip has multiple locking holes along its length, and one end of the adjusting strip away from the abutment block extends into a pre-drilled hole in the wall. When the fireproof board 1 and fireproof board 2 located on both sides of the wall abut against the side wall, the two adjusting strips are pulled until the two locking holes are coaxial. A locking post is inserted into and penetrates the locking hole. After the adjusting strip is locked and fixed, the fireproof board 1 and fireproof board 2 are spliced ​​and fitted onto the fireproof cable tray, and the side wall of the abutment block abuts against the fireproof board 1 and fireproof board 2.

[0011] Optionally, a limiting block is fixedly connected to the side wall of the fireproof cable tray. A dovetail groove is formed on the upper surface of the limiting block along the length of the fireproof cable tray. A dovetail block is slidably connected to the dovetail groove, and the protruding end of the dovetail block is fixedly connected to the bottom of the abutment block.

[0012] Optionally, protective pads are provided on the side of the fireproof board one and fireproof board two facing the wall.

[0013] Optionally, the limiting component includes multiple grooves formed along the through direction of the fixing hole. A spring is fixed in each groove. When the spring is in its natural state, it extends out of the groove opening, and the extension and contraction direction of the spring is perpendicular to the through direction of the fixing hole. The other end of the spring is fixed with a slidably connected inclined block in the groove. Both the upper and lower sides of the inclined block are provided with inclined surfaces. The inclined sidewall of the wedge block abuts against the inclined surface of the inclined block. The top end of the limiting rod extends out of the fixing hole and is fixed with a stop block. The diameter of the stop block is larger than the diameter of the fixing hole.

[0014] In summary, this application includes the following beneficial technical effects: Fireproof board one and fireproof board two are spliced ​​structures, and the sliding connection between fireproof board one and fireproof board two can effectively prevent flames from spreading. Moreover, when disassembling, fireproof board one and fireproof board two installed on the fireproof cable tray can be directly disassembled, which is more convenient and does not require disconnecting the cable tray and cables for construction.

[0020] The following is a further detailed description of this application in conjunction with the attached Figure 1-4 drawings.

[0021] The embodiment of this application discloses a wall-passing structure of a fireproof cable tray.

[0022] Referring to Figure 1 , the wall-passing structure of the fireproof cable tray includes a fireproof cable tray and a fixing mechanism sleeved on the fireproof cable tray. The fixing mechanism includes two groups of fixing components 1. One group of fixing components 1 abuts against and seals one side of the wall 13, and the other group of fixing components 1 abuts against and seals the other side of the wall 13. Each group of fixing components 1 includes a first fireproof board 11 and a second fireproof board 12. The first fireproof board 11 and the second fireproof board 12 are spliced along the side line of the bottom side wall of the fireproof cable tray. The two ends of the first fireproof board 11 are bent downward and protrude from the side wall of the fireproof cable tray. The opening formed in the middle after the first fireproof board 11 is bent just sleeved on the fireproof cable tray. The second fireproof board 12 can be a long strip-shaped plate body. After splicing, it seals the opening of the first fireproof board 11. The first fireproof board 11 and the second fireproof board 12 form a complete "square frame" - shaped plate body after splicing and are sleeved on the fireproof cable tray. After the fireproof cable tray passes through the wall and the hole is blocked, the side of the first fireproof board 11 and the second fireproof board 12 facing the wall 13 is fixedly sealed with fireproof glue, so as to prevent fire from spreading due to fire passing through the gap between the first fireproof board 11 and the second fireproof board 12.

[0023] The first fireproof board 11 and the second fireproof board 12 are fixed by clamping. The side walls of the first fireproof board 11 and the second fireproof board 12 that abut against each other are provided with a chute with a T-shaped cross-section, and one end of the chute is open along the length direction. The second fireproof board 12 is provided with a T-shaped clamping block 121 that is slidably connected to the chute. Thus, after the second fireproof board 12 is slidably connected to the first fireproof board 11, the two are limited up and down, preventing the second fireproof board 12 from falling off after splicing, which helps to make the splicing more firm.

[0024] According to the above configuration, fireproof board 11 and fireproof board 2 are spliced ​​structures. When disassembling, fireproof board 11 and fireproof board 2 can be directly disassembled from the fireproof cable tray, which is more convenient. They are spliced ​​in the form of T-shaped grooves to form a closed "U" shape, which minimizes fire leakage due to gaps and eliminates the need for drilling holes and fixing bolts, making assembly and disassembly more convenient.

[0025] A locking assembly 2 is provided between fireproof board 11 and fireproof board 22. The locking assembly 2 includes a fixing hole 21 and a limiting rod 22. Fireproof board 11 and fireproof board 22 are each provided with at least one fixing hole 21 (i.e., one on each side of each board) which is opened along its height direction and penetrates through it. The fixing holes 21 of fireproof board 11 and fireproof board 22 are opened in the area where the two can abut against each other. After fireproof board 11 and fireproof board 22 are spliced, the fixing holes 21 on fireproof board 11 and fireproof board 22 are coaxial.

[0026] After fireproof board 11 and fireproof board 22 are spliced ​​together, the limiting rod 22 penetrates and fixes the two boards into a complete board body. The top of the limiting rod 22 is provided with a stop block 221 with a diameter larger than the fixing hole 21. The stop block 221 and the limiting rod 22 are detachably connected. So when the limiting rod 22 penetrates to the required position, the stop block 221 abuts against the port of the fixing hole 21 to prevent the limiting rod 22 from falling further or shifting.

[0027] Reference Figure 2 The limiting rod 22 extends outward with a wedge block 23 for limiting. The wedge block 23 is an inverted trapezoid, that is, wider at the top and narrower at the bottom, and the side wall is inclined. The side wall of the wedge block 23 can abut against the hole wall as much as possible, thereby greatly reducing the possibility of vibration or displacement. The hole wall of the fixing hole 21 is provided with a limiting component 3 for limiting the limiting rod 22. The limiting component 3 includes an inclined block 31 that abuts against the wedge block 23. Both the upper and lower sides of the inclined block 31 are provided with inclined surfaces. One inclined end of the inclined block 31 abuts against the inclined side wall of the wedge block 23. The inclined surface of the inclined block 31 and the inclined surface of the wedge block 23 can have the same inclination.

[0028] The limiting component 3 also includes multiple grooves, wherein the number of grooves is at least one and corresponds one-to-one with the number and position of wedge blocks 23 and inclined blocks 31. The grooves are opened along the through direction of the fixing hole 21. A spring 32 is provided in the groove. The extension and retraction direction of the spring 32 is perpendicular to the through direction of the fixing hole 21. The other end of the spring 32 is fixed to the inclined block 31 located in the groove.

[0029] With the above configuration, under the action of the wedge block 23 and the inclined block 31 and the action of the spring 32, the limiting rod 22 can only be pushed downward. When there is no external force, it abuts against the inclined block 31. The spring 32 supports the inclined block 31 to extend out of the groove. The inclined block 31 abuts against the inclined side wall of the wedge block 23. If it is necessary to disassemble the fireproof plate 11 and the fireproof plate 22, the limiting rod 22 can be pulled out from the fixing hole 21.

[0030] The limiting rod 22 penetrates the fixing hole 21 to further align the two when splicing. After the limiting rod 22 penetrates the fireproof board 11 and the fireproof board 22, it forms a limit through the stop block 221.

[0031] With the above configuration, the fixing holes 21 of fireproof board 11 and fireproof board 22 are coaxial after splicing. The vertical limiting rod 22 can effectively prevent the lateral displacement of fireproof board 11 and fireproof board 22 after insertion. At the same time, the snap-fit ​​structure of fireproof board 11 and fireproof board 22 can effectively prevent the vertical displacement of fireproof board 11 and fireproof board 212, thereby further optimizing the fixing effect of the two.

[0032] Reference Figure 1 and Figure 4 The fixing component 1 also includes abutment blocks 14 slidably connected to the side wall of the fireproof cable tray. In this embodiment, three abutment blocks 14 are provided and distributed on the top surface and the three side walls on the left and right sides of the fireproof cable tray. Each abutment block is connected to an adjusting strip 15 for pressing the fireproof plate 11 and fireproof plate 12 located on both sides of the wall 13 tightly against the wall surface. One end of the adjusting strip 15 opposite to the abutment block 14 extends into the hole, and the adjusting strips 15 of two symmetrical abutment blocks 14 overlap. Each adjusting strip 15 is provided with a locking hole along its length direction, and there may be at least three locking holes.

[0033] When fireproof panels 11 and 12, located on both sides of wall 13, abut against the sidewalls of wall 13, pull the locking holes of the two adjusting straps 15 to coaxiality. A locking post 16 is then inserted into and penetrates the locking hole. After the locking post 16 is inserted, the adjusting straps 15 are positioned. After positioning, fireproof panels 11 and 12 can be temporarily left unassembled. After sealing material is inserted into the hole, the installation of fireproof panels 11 and 12 can be carried out later. It should be noted that the pre-drilled holes are larger than the width of the fireproof cable tray, leaving space for workers to reach into the holes and insert the locking post 16.

[0034] To further prevent the adjusting belt 15 from moving, a magnet can be installed at the bottom of the locking post 16. After insertion, the magnet will adhere to the outer wall of the fireproof cable tray, thereby further fixing the position of the abutment block 14. The multiple locking holes can be dragged and adjusted as needed to adjust the position of the abutment block 14. After moving to the desired position, the locking post 16 is inserted. The abutment block 14 is used to abut against the side walls of fireproof board 11 and fireproof board 2 12. The distance of the abutment block 14 can be adjusted by the adjusting belt 15, thereby further ensuring that the abutment block 14 is adjusted according to the different specifications of fireproof board 11 and fireproof board 2 12 and abuts against the side walls of fireproof board 11 and fireproof board 2 12.

[0035] Reference Figure 1 and Figure 4 Fireproof board 11 and fireproof board 2 12 both have horizontal plates 18 extending from the side of the abutment block 14, which are abutting against the side wall of the fireproof cable tray. The side wall of the horizontal plate 18 is used to abut against the abutment block 14 and limit the position of fireproof board 11 and fireproof board 2 12, and assists in fixing the fireproof board 11 and fireproof board 2 12 after filling the gaps with fireproof glue.

[0036] Reference Figure 1 and Figure 4 The four side walls of the fireproof cable tray are respectively fixedly connected to limit blocks 17 by screws. The upper surface of the limit block 17 is provided with a dovetail groove along the length of the fireproof cable tray. The dovetail groove is slidably connected to the dovetail block. In order to facilitate the insertion of the abutment block 14, one of the sealed ends of the two limit blocks 17 can be detachably fixed by bolts. The height of the fixed position of the horizontal plate 18 is greater than the height of the limit block 17, so the limit block 17 will not obstruct the horizontal plate 18 from abutting against the abutment block 14.

[0037] With the above settings, the abutment block 14 is engaged and slids within the cavity of the limiting block 17. Since the bottom of the abutment block 14 is fixed with a dovetail block, the abutment block 14 located on the lower surface of the fireproof cable tray will not fall off.

[0038] Fireproof board 11 and fireproof board 2 12 are fitted with protective pads on the side facing the wall 13. These pads can be made of compressible or elastic materials such as fire-resistant cotton. When fireproof board 11 and fireproof board 2 12 are joined together and pressed against the wall 13, the protective pads can be compressed, resulting in a tighter and more airtight seal. After the protective pads are in place, a seal is formed between the protective pads and the wall 13 using fire-retardant adhesive or similar materials. The protective pads and fireproof boards 11 and 2 12 can be secured with screws. Based on this design, when fireproof board 11 and fireproof board 2 12 need to be disassembled, the fire-retardant adhesive largely adheres to the protective pads, greatly preserving the integrity of fireproof board 11 and fireproof board 2 12. Therefore, fireproof board 11 and fireproof board 2 12 can be reused after disassembly.

[0039] Fireproof board 11 and fireproof board 2 12 are placed on the fireproof cable tray. By observing the position of the horizontal plate 18 of fireproof board 11 and fireproof board 2 12, the positions of multiple abutment blocks 14 are adjusted. After adjustment, the locking post 16 is inserted to fix the position of the abutment block 14. Fireproof board 11 and fireproof board 2 12 are slid together and fireproof adhesive is filled between the finally spliced ​​board and the wall 13 for sealing, thus completing the sealing of the through-wall structure.

[0040] 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.
