[0002] Currently, high-rise and multi-story buildings are generally designed with electrical shafts. Vertical cable trays are installed in the electrical shafts. During the construction phase, openings need to be reserved when the floor slab is poured. After the ground is formed, the vertical cable trays that pass through the floor slab are installed and fixed. Then, the gap between the cable trays and the reserved openings is sealed with fireproof sealant.

[0003] However, current connectors cannot be easily disassembled and assembled, affecting the efficiency of cable tray installation and replacement. At the same time, it is inconvenient to adjust the height of the cable tray as needed. Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a pre-embedded fireproof electrical shaft cable tray through-floor connector to overcome the defects in the existing technology.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example: Figure 1-4 As shown, this utility model provides a technical solution: a pre-embedded fireproof electrical shaft cable tray through-floor connector, including an outer frame 1, and an assembly and adjustment mechanism 2 is provided inside the outer frame 1. The assembly and adjustment mechanism 2 includes an installation groove 201, a sealing plate 202, a slot 203, an adjustment rod 204, a locking nut 206, and a pre-embedded threaded cylinder 207.

[0034] An installation groove 201 is provided inside the outer frame 1. A sealing plate 202 is movably connected inside the installation groove 201. The top of the sealing plate 202 has slots 203 at equal intervals. An adjusting rod 204 is movably connected inside the slots 203. A pad frame is sleeved on the outside of the adjusting rod 204 at the bottom position of the outer frame 1. A locking nut 206 is threaded on the outside of the adjusting rod 204 at the bottom position of the pad frame. A pre-embedded threaded cylinder 207 is threaded on the bottom position of the outside of the adjusting rod 204. To facilitate the adjustment of the position of the outer frame 1, an internal hexagonal hole is provided at the top of the adjusting rod 204. A protrusion is engaged at the bottom position of the pre-embedded threaded cylinder 207.

[0035] The outer frame 1 is equipped with a clamping and positioning mechanism 3, which includes a positioning cylinder 301, a connecting rod 302, an internal threaded bushing, a pressure plate 304, a through hole 305 and a sealing cover;

[0036] A positioning cylinder 301 is equidistantly engaged at the bottom end of the outer frame 1. A connecting rod 302 is threadedly connected to the inner wall of the positioning cylinder 301. An internal threaded bushing is threadedly sleeved at the top position of the outer side of the connecting rod 302. A pressure plate 304 is sleeved on the outer side of the internal threaded bushing. A through hole 305 is equidistantly opened at the top of the pressure plate 304 corresponding to the top position of the adjusting rod 204. A sealing cover is threadedly connected inside the through hole 305. In order to facilitate the movement of the pressure plate 304, the outer side of the pressure plate 304 fits against the inner wall of the outer frame 1. The inner diameters of the pressure plate 304, the sealing plate 202 and the pad frame are all equal.

[0037] The space between the sealing plate 202 and the gasket inside the outer frame 1 is filled with expanding fireproof putty 4. Ceramic fiber cloth 5 is provided on the top of the expanding fireproof putty 4. Circular holes 6 are opened inside the expanding fireproof putty 4 and the ceramic fiber cloth 5, corresponding to the outer side of the adjusting rod 204 and the outer side of the connecting rod 302. In order to improve the fireproof performance of the connector, the outer sides of the expanding fireproof putty 4 and the ceramic fiber cloth 5 are in contact with the inner wall of the outer frame 1.

[0038] The working principle and usage process of this utility model are as follows: First, the pre-embedded threaded cylinder 207 is cast into the floor slab and kept perpendicular to the floor slab. Then, the sealing plate 202 is placed into the installation groove 201, and the adjusting rod 204 is passed through the sealing plate 202 and the gasket frame and fixed by the locking nut 206 to complete the assembly of the pre-embedded part. Then, the adjusting rod 204 is rotated into the pre-embedded threaded cylinder 207 to fix the position of the connector and improve the stability of the connector.

[0039] Next, during the splicing process, expanding fireproof mud 4 is filled between the sealing plate 202 and the gasket frame, and ceramic fiber cloth 5 is placed on top of the expanding fireproof mud 4, thereby improving the fire resistance of the connector through double-layer fireproof measures.

[0040] Next, the cable tray is inserted into the outer frame 1, and the pressure plate 304 is installed on the connecting rod 302 through the internal threaded bushing. Then, the pressure plate 304 is fixed inside the outer frame 1 by the cooperation of the connecting rod 302 and the positioning cylinder 301. Then, the internal threaded bushing is rotated to bring the pressure plate 304 down along the connecting rod 302, so that the pressure plate 304 and the sealing plate 202 cooperate to clamp and limit the cable tray, which facilitates the assembly and disassembly of the cable tray.

[0041] Finally, rotating the sealing cover releases the fit against the through hole 305, allowing the adjusting rod 204 to be rotated through the through hole 305, thereby moving the outer frame 1 and the cable tray, changing the position of the cable tray and improving its adaptability.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
