Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The fireproof flame-retardant safe cable bridge as shown in the attached figures 1 to 2 comprises a concave groove box 1, a concave lower flame-retardant plate 2 and a concave inner frame plate 3. The lower flame-retardant plate 2 is arranged on the inner wall of the groove box 1, and the outer wall of the lower flame-retardant plate 2 is tightly attached to the inner wall of the groove box 1. The inner frame plate 3 is arranged on the inner wall of the lower flame-retardant plate 2, and the outer wall of the inner frame plate 3 is tightly attached to the inner wall of the lower flame-retardant plate 2. The inner frame plate 3 is used for clamping and fixing the lower flame-retardant plate 2, and the inner wall of the inner frame plate 3 is used for placing cables.
As shown in the attached drawing 1, the upper side of the groove box 1 is slidably clamped with a cover plate 4 in an inverted concave shape, the inner walls of the two sides of the cover plate 4 are respectively provided with a separation plate 5, the separation plate 5 is integrally formed by a horizontal transverse plate 6 and a vertical plate 7 at the end part of the transverse plate 6, a space is reserved between the transverse plate 6 and the inner wall of the upper side of the cover plate 4, and an upper flame retardant plate 8 is arranged in the space. The inner wall of the groove box 1, the lower board surface of the transverse board 6 and the outer board surface of the vertical board 7 form an upper groove 9, and the upper end of the lower flame-retardant board 2 is correspondingly clamped in the upper groove 9. The upper end of the lower flame-retardant plate 2 is fixed by clamping, so that the connection strength is improved.
The exploded schematic view of each part of the bridge frame is shown in the attached drawing 2, the upper flame-retardant plate 8 and the lower flame-retardant plate 2 are arranged in the bridge frame in a sliding and inserting mode, the laying and the installation are more convenient, and the maintenance is also facilitated.
The upper flame-retardant plate 8 is a horizontal plate body, two sides of the lower plate surface of the upper flame-retardant plate 8 are respectively provided with a lower extension plate 10, and the outer plate surface of the lower extension plate 10 is correspondingly attached to the inner plate surface of the vertical plate 7; the lower end of the lower extension plate 10 and the upper end of the lower flame retardant plate 2 have an overlapping portion in the vertical direction. The existence of the overlapped part enables the upper flame-retardant plate 8 and the lower flame-retardant plate 2 to enclose a cavity for placing a cable in the bridge, so that the fireproof and flame-retardant performance is improved.
An inserting plate 11 is horizontally arranged at the lower end of the lower extending plate 10 in an outward extending mode, and a slot 12 is formed between the lower plate surface of the vertical plate 7 and the upper plate surface of the inner frame plate 3; the inserting plate 11 is correspondingly inserted into the inserting groove 12. The lower extension board 10 and the inserting board 11 are both part of the upper flame-retardant board 8 and also have fireproof and flame-retardant properties. Due to the arrangement of the inserting plate 11, the upper flame-retardant plate 8 and the lower flame-retardant plate 2 are enclosed more tightly, and the fireproof performance is better.
The lower board surface of the inserting board 11 is provided with a clamping groove 13, and the upper board surface of the inner frame board 3 is provided with a clamping block 14. The clamping blocks 14 are correspondingly inserted into the clamping grooves 13, so that the inserting plate 11 and the inner frame plate 3 are relatively limited, the overall connection strength of the bridge is improved, the end part of the inserting plate 11 can be tightly attached to the inner wall of the lower flame-retardant plate 2, namely, the upper flame-retardant plate 8 and the lower flame-retardant plate 2 are enclosed more tightly, and the fireproof effect is improved.
The clamping block 14 and the clamping groove 13 are mutually matched and tapered, so that the clamping block 14 and the clamping groove 13 are more easily mutually matched and inserted in the installation process, and the installation is smoother.
The length of the overlapped part of the lower extension plate 10 and the lower flame-retardant plate 2 is larger than the sum of the thicknesses of the upper flame-retardant plate 8 and the lower flame-retardant plate 2, and enough overlapped part can ensure the fire-proof performance when the upper flame-retardant plate 8 and the lower flame-retardant plate 2 are surrounded.
