Description

TECHNICAL FIELD

[0001] The utility model relates to a fireproof plate, especially a fireproof plate with modularized threading holes. BACKGROUND

[0002] Cables need to pass through the holes on the walls of a computer room. In order to prevent the spread of fire through the holes on the walls to the computer room, a fireproof plate is installed in the wall hole. The fireproof plate has threading holes for cables to pass through. Fireproofing mortar is used to seal the gap between the cables and the threading holes. If new cables need to pass through, new threading holes need to be opened on the fireproof plate, or even the wall needs to be damaged. Chinese utility model patent document CN209016632U discloses a substation cable trench wall-penetrating sealing plate. The sealing plate includes a front fireproof plate, a rear fireproof plate, and a plurality of hollow tubes. The hollow tubes are filled with fireproofing mortar. All the hollow tubes pass through the front and rear fireproof plates in parallel. The two ends of the hollow tubes are fixed to the front and rear fireproof plates, respectively. The two ends of the hollow tubes are provided with sealing covers. The installer places the sealing plate on the wall in advance, opens the sealing cover, and removes the fireproofing mortar. Then, the cables pass through the hollow tubes, and the fireproofing mortar is backfilled. In this way, the cables can pass through the wall. If new cables need to be added to the hollow tubes through which the cables have already passed, the fireproofing mortar previously filled in the hollow tubes needs to be cleaned. The fireproofing mortar may have already solidified. Therefore, after the newly added cables pass through, the un-solidified fireproofing mortar needs to be refilled. The solidified fireproofing mortar adheres to the hollow tubes, which requires a lot of manpower and time to clean. Refilling the fireproofing mortar also increases the material cost. SUMMARY

[0003] The utility model provides a fireproof plate with modularized threading holes to reduce the step of filling the gap with fireproofing mortar.

[0004] To solve the above technical problems, the utility model provides a fireproof plate with modularized threading holes. The fireproof plate has through holes that pass through front to back. The cross section of the through holes is in the shape of a horizontal strip. A plurality of threading modules are arranged horizontally in the through holes. The threading modules include a fire-retardant plate and an elastic fire-retardant component installed on the fire-retardant plate. The elastic fire-retardant component has threading holes for cables to pass through. The elastic fire-retardant component covers the cables when the cables pass through the elastic fire-retardant component by overcoming the elastic force. The fireproof plate is provided with fireproof covers that can cover the openings of the threading holes.

[0005] Further, the two opposite side plates of the fire-retardant plate in the threading module each have a sliding groove. The fireproof plate is provided with horizontal guide rails on the upper and lower hole walls of the through holes. The threading modules can move along the guide rails.

[0006] Further, the fireproof plate is provided with vertical fixing holes penetrating front and back, and the fixing holes are connected with the through holes to allow the threading modules to be installed on the guide rail one by one from the connection; and a fixing cover is arranged to cover the fixing holes to prevent the threading modules from moving along the guide rail and separating from the fixing holes.

[0007] Further, A. one of the threading modules is a small-diameter threading module with a threading hole diameter of 10 mm; and / or B. one of the threading modules is a medium-diameter threading module with a threading hole diameter of 15 mm; and / or one of the threading modules is a large-diameter threading module with a threading hole diameter of 20 mm.

[0008] The fireproof plate with modular threading holes provided by the utility model is provided with the threading hole of the elastic flame-retardant component for the cable to pass through, and the cable is covered when passing through the elastic flame-retardant component, so that the gap between the cable and the flame-retardant plate is filled, and the gap does not need to be filled with fireproof mud.

The wiring module 2 is as follows: Figure 2 As shown, it includes a square flame-retardant plate 21, with corresponding horizontal grooves 24 on each of the two opposite side plates of the flame-retardant plate 21, such as... Figure 3 As shown, the slide 24 cooperates with the guide rail 12 on the fireproof board 1, thereby enabling the wire-threading module 2 to move on the guide rail 12. The fireproof board 1 has vertically extending fixing holes 13, which connect to two through holes 11. Multiple wire-threading modules 2 are inserted horizontally from right to left into the guide rail 12 on the wall of the through hole 11, arranged horizontally within the through hole 11. Then, a fixing cover 3 is used to cover the fixing hole 13; the fixing cover 3 is as follows... Figure 6 As shown, its protrusion 31 is inserted into the fixing hole 13 to prevent the wire threading module 2 from moving along the guide rail 12 and disengaging from the fixing hole 13.

If the cable 4 does not need to pass through the wiring module 2, the fireproof cover 25 covers the opening of the wiring hole 23; the fireproof cover 25, as shown... Figure 5 As shown, its flange 251 is inserted into the wire hole 23 to prevent the fire from spreading through the wire hole 23; the wire module is as follows Figure 4 The fireproof cover 25 is shown.

Any small-diameter threading module 26 can be replaced with... Figure 8 The medium-diameter threading module 27 or the large-diameter threading module 28 shown are used. The threading hole 23 of the medium-diameter threading module 27 has a diameter of 15mm, and the threading hole 23 of the large-diameter threading module 28 has a diameter of 20mm.
