Description
Technical Field
[0001] The utility model specifically relates to the technical field of busway plugging, and particularly relates to a wall-penetrating busway with a plugging structure. Background Technique
[0002] The fireproof and waterproof plugging of the wall-penetrating holes of the busway is an important measure to ensure the safe operation of the electrical system and the overall safety of the building. The busway passes through the holes reserved in the wall, and then fireproof mud or fireproof board is stuffed into the gap between the hole and the busway to seal the gap.
[0003] The plugging of the wall-penetrating holes of the busway in modern buildings is mainly composed of two products, fireproof mud and fireproof board. As the application of busways in humid places such as multi-layer underground spaces and outdoor areas with marine climates becomes more and more extensive, previously, only the solution to meet the fire separation design was more considered, and now problems and difficulties such as waterproofing and moisture-proofing are faced. As the use time of the fireproof mud or fireproof board increases, the fireproof mud or fireproof board is easily eroded by the humid environment, resulting in a decrease in the adhesion at the position in contact with the wall, thus forming a gap between the wall and the fireproof mud or fireproof board, affecting the sealing effect and unable to seal and plug the wall-penetrating holes in the ground or indoor and outdoor areas where leakage and water seepage are likely to occur. Content of the Utility Model
[0004] The purpose of the utility model is to provide a wall-penetrating busway with a plugging structure. A plugging shell is installed on the outer side of the busway, and then a three-proof foaming glue is poured into the plugging shell. By using the expansion effect of the three-proof foaming glue, the gap is filled, so as to play a role in sealing and waterproofing, and the components of the three-proof foaming glue can play a role in fire prevention. To solve the technical problems proposed in the above background technique.

[0031] In this embodiment, an installation hole 22 is opened at the bottom of the template outer shell 21, and the installation hole 22 is arranged in a fitting manner on the outer side of the busbar trunking 1 to reduce the gap at the connection
[0032] In this embodiment, a plurality of fixed card seats 23 are integrally arranged on the inner side of the template housing 21. Two symmetrically arranged fixed card seats 23 form a group, and each group of fixed card seats 23 is arranged in a rectangular array. A slot 24 is formed in each fixed card seat 23.
[0033] In this embodiment, the high-strength support 4 includes a metal partition 41 inserted into the inner side of the template housing 21, and both ends of the metal partition 41 are inserted into the fixed card seats 23.
[0034] In this embodiment, limit guide rails 42 corresponding to the slots 24 are integrally arranged at both ends of the metal partition 41 to fix the position of the metal partition 41 and prevent the metal partition 41 from shaking inside the fixed card seat 23.
[0035] In this embodiment, a groove is formed at the bottom of the metal partition 41, and a reinforcing guard plate 43 is integrally arranged corresponding to the groove to reinforce the internal structure of the metal partition 41. The busbar trunking 1 passes through the inside of the reinforcing guard plate 43.
[0036] In this embodiment, a metal partition 41 is inserted into each group of fixed card seats 23, and the three-proof foaming glue is located between every two metal partitions 41, which increases the internal structure of the three-proof foaming glue after pouring and improves the fireproof effect.

The metal partition 41 supports the inside of the template housing 21, improves the structural strength inside the template housing 21, and prevents the template housing 21 from deforming due to the expansion of the three-proof foaming glue. At this time, the reinforcement plate 43 is located outside the bus duct 1 and does not affect the normal connection between the bus duct 1 and the template housing 21. Then pour the three-proof foaming glue into the inside of the template housing 21. After the three-proof foaming glue expands, it fills the gaps between the bus duct 1 and the reinforcement plate 43 and between the bus duct 1 and the installation hole 22 to seal them. Finally, embed the template housing 21 into the wall hole.
