Description

Technical Field

[0001] This utility model belongs to the field of cable support and cable fire protection technology, and in particular relates to a detachable fireproof partition installation structure suitable for cable supports. Background Technology

[0002] In renovation and expansion projects, it is often necessary to add, replace, or remove cables already laid in the previous project. Due to space constraints, it is often necessary to dismantle the fireproof cable barriers installed in the previous project during these cable modification processes. Currently, the commonly used method for assembling fireproof barriers is a one-time, non-removable fixing method. Dismantling these existing fireproof barriers causes extensive damage to the fireproof cable barriers already installed in the previous project. This not only results in a significant waste of fireproof barriers but also greatly increases the workload and may even affect the project schedule. Utility Model Content

[0003] This utility model aims to solve the problem that the process of dismantling the installed fireproof partitions can cause extensive damage to the fireproof partitions of the cables that have been installed in the previous project. It provides a detachable fireproof partition installation structure suitable for cable supports, which can not only effectively prevent the spread of flames between the layers of the cable support, but also prevent damage to the fireproof partition installation structure during the dismantling and installation of the fireproof partitions. This avoids repeated construction of fireproof partitions, saves materials, reduces the amount of construction work, and improves the convenience of cable replacement.

[0004] To achieve the above-mentioned utility model objectives, this utility model provides a detachable fireproof partition installation structure suitable for cable supports, including detachable hardware, a fireproof partition, and a cable support. The fireproof partition is a channel-shaped structure, comprising a bottom fireproof partition and one fireproof partition on each side. The inner fireproof partition of the cable support is fixed to the bottom fireproof partition using angle steel and mounting bolts, while the outer fireproof partition of the cable support is installed to the cable support using detachable hardware and mounting bolts. The detachable hardware is a T-shaped plate structure. The upper horizontal plate-shaped portion of the T-shaped plate-shaped structure is reliably fixed to the fireproof partition on the outer side of the fireproof channel using mounting bolts, while the lower vertical plate-shaped portion is bolted to the cable support.

[0005] Furthermore, a steel plate is welded to the outer end of the cable bracket, and the surface of the welded steel plate is in contact with the mounting surface of the lower vertical plate-shaped part of the detachable hardware.

[0006] This invention not only effectively prevents flames from spreading between cable support layers, but also ensures that the fireproof partition installation structure is not damaged during the installation and removal of the fireproof partition. This avoids damage to the fireproof partition structure of the cables already installed in the previous project during the renovation and expansion of the project, saving the amount of fireproof partition material, reducing the amount of construction work, and improving the convenience of cable replacement.

[0007] This utility model of hardware is easy to install, has a clear structure, and is widely applicable to various engineering projects, effectively improving the convenience of engineering construction. Attached Figure Description

[0011] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a detachable fireproof partition installation structure suitable for cable supports.

[0012] Reference Figure 1 and Figure 2This patent proposes a detachable fireproof partition installation structure suitable for cable supports. The fireproof partition 2 is a channel-shaped structure, with cables 4 arranged inside the channel. The channel-shaped structure consists of a bottom fireproof partition and one fireproof partition on each side. The inner fireproof partition of the cable support 5 is fixed to the bottom fireproof partition using angle steel 6 and mounting bolts, while the outer fireproof partition of the cable support 5 is installed to the cable support using detachable hardware 1 and mounting bolts 3. This channel-shaped fireproof partition assembly structure can effectively prevent the spread of flames between cable support layers. The detachable hardware 1 is a T-shaped plate structure. The upper part of the T-shaped plate structure is reliably fixed to the fireproof partition on the outside of the fireproof channel using mounting bolts. The upper outer contour dimension of the detachable hardware is 150mm × 50mm, with 4 bolt holes. The center distance between the holes and the distance from the center of the hole to the edge of the hardware are both 30mm. The diameter of each bolt hole is 10mm. The mounting bolts are 4×M8 bolts, and a gasket is used for transition between the mounting bolts and the fireproof partition. The lower vertical plate-shaped part of the detachable hardware is reliably bolted to the cable bracket. A steel plate needs to be welded to the outer end of the cable bracket, and the surface of the welded steel plate must fit snugly against the mounting surface of the lower vertical plate-shaped part of the hardware. The lower outer contour dimensions of the hardware are 50mm × 50mm. A bolt hole is located at the center of the lower part of the hardware, 25mm from the edge of the hardware, with a diameter of 10mm. A single M8 bolt is used for mounting, and a washer is used for transition between the bolt and the mounting surface of the cable bracket. When it is necessary to remove the fireproof partition, simply remove the mounting bolts from the lower part of the detachable hardware that are mounted on the cable bracket to remove the outer fireproof partition of the cable tray. After completing the cable modification work, the removed fireproof partition, along with the hardware, is reinstalled on the cable bracket using the mounting bolts at the lower part of the hardware, thus restoring the cable tray assembly.
