Description

Technical Field

[0001] This utility model belongs to the field of cable shaft technology, and in particular relates to a unit-combined fireproof cable shaft. Background Technology

[0002] Cable shafts are vertical channels in buildings or industrial facilities specifically designed for laying power cables. On the one hand, they integrate multiple types of cables, avoiding the chaos of scattered laying; on the other hand, they solve the need for power, communication, fire protection and other power cables between floors; ensuring line safety and facilitating maintenance.

[0003] When installing cables in cable shafts, it is necessary to carefully measure the dimensions on-site and cut the fireproof boards before installing them on the keel. This process is time-consuming and makes it difficult to control the quality. In addition, the interior of cable shafts is mostly a through cavity. Due to the large number and complexity of cables, the cables are messy and disorderly after installation, making it difficult to meet the acceptance requirements of the "Code for Acceptance of Construction Quality of Building Electrical Engineering GB50303-2015" and affecting daily maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a modular fireproof cable shaft to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A modular fireproof cable shaft includes: multiple shaft units, which are arranged longitudinally and adjacent shaft units are detachably connected.

[0007] Each of the vertical shaft units includes a frame, a fireproof plate, and at least one fixing rod; the frame is in the shape of a cuboid, with the fireproof plate provided on each of its four sides, and the fixing rod is horizontally arranged inside, the fixing rod being used to connect power cables and / or optical cables and control cables;

[0008] The two adjacent shaft units are detachably connected via the frame.

[0009] As a further improvement of this utility model, the top and bottom of the frame are provided with longitudinally corresponding through holes;

[0010] The two adjacent frames are detachably connected by bolts passing through through holes at the bottom of the upper frame and the top of the lower frame.

[0011] As a further improvement of this utility model, the frame is made of steel.

[0012] As a further improvement of this utility model, the fireproof board is connected to the frame by bolts.

[0013] As a further improvement of this utility model, the fixing rod is disposed above the interior of the frame.

[0014] The beneficial effects of adopting the above technical solution are as follows:

[0015] This utility model adopts a modular construction method for cable shafts, which is simple and efficient, suitable for on-site assembly, and has high installation efficiency; it also saves transportation costs and reduces overall costs. The shaft unit includes a frame, fireproof board, and fixing rods. In actual use, there is no need to cut the fireproof board, reducing construction time and improving construction efficiency; the fixing rods divide the space within the frame into smaller spaces, making it easy to place cables of different sizes or functions in different spaces, resulting in neat and orderly cable arrangement.

[0020] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0021] like Figure 3 Use steel to wrap the cable to form a frame 2.

[0022] like Figures 1-3 The illustrated unit-combined fireproof cable shaft includes: multiple shaft units 1, which are arranged longitudinally and adjacent shaft units 1 are detachably connected; during transportation, the shaft units 1 or individual components of the shaft units 1 are transported, occupying little space.

[0023] Each of the vertical shaft units 1 includes a frame 2, a fireproof board 3, and at least one fixing rod 4; the frame 2 is in the shape of a cuboid and is made of steel, such as angle steel or square tube steel welded or bolted together.

[0024] The fireproof board 3 is provided on all four sides of the frame 2. In actual use, there is no need to cut the fireproof board 3, reducing construction time and improving construction efficiency. In this embodiment, the fireproof board 3 is connected to the frame 2 by bolts, specifically the connection between the fireproof board 3 and the steel of the frame 2.

[0025] The fixing rod 4 is horizontally installed inside the frame 2. The fixing rod 4 is used to connect the power cable 5 and / or optical cable and control cable 6. Furthermore, the fixing rod 4 is located at the top inside the frame 2, i.e., connected to the upper steel structure of the frame 2. The fixing rod 4 divides the space inside the frame 2 into smaller spaces, facilitating the placement of cables of different sizes or functions in different spaces. If cable fixing is required, cable ties can be used to connect the cables to the fixing rod 4, ensuring a neat and orderly cable arrangement. The connection method between the fixing rod 4 and the frame 2 is not specifically limited; it can be integrally formed by welding or detachably connected by bolts, plug-in connections, etc.

[0026] Two adjacent shaft units 1 are detachably connected via the frame 2. Specifically, the top and bottom of the frame 2 are provided with longitudinally corresponding through holes 7; two adjacent frames 2 are detachably connected by bolts passing through the through holes 7 of the upper frame 2 at the bottom and the lower frame 2 at the top.

[0027] During actual installation, the fireproof board 3 is first bolted onto the frame 2. Then, the frame 2 is connected layer by layer from bottom to top using bolts. Cables are passed through the space partitioned by the fixing rod 4 according to their function or size, and are fixed to the fixing rod 4 with cable ties. The height of the frame 2 is the height of the shaft unit 1. The above operation is repeated until the installation is close to the top of the room. When the gap between the frame 2 and the ceiling is less than the height of the frame 2 (first height), a second height frame 2 is fabricated on-site for subsequent installation. The height of the second height frame 2 is determined by the following two methods.

[0028] The first method involves fabricating a unit smaller than the first height on-site if the gap is greater than or equal to half the first height, ultimately forming a vertical shaft unit 1. For example, if the height of vertical shaft unit 1 is 460mm and the gap is 240mm, then a 240mm vertical shaft unit 1 is fabricated as the top vertical shaft unit 1.

[0029] The second method involves fabricating two units smaller than the first height on-site if the gap is less than half the height of the first height, ultimately forming a vertical shaft. For example, if the unit height is 460mm and the final distance is 200mm, then two 330mm vertical shaft units 1 (calculated as (460mm + 200mm) / 2 = 330mm) are made as the two top vertical shaft units 1.

[0030] This utility model adopts a combined mode to manufacture 5 vertical shafts for power cables. The process is simple and efficient, suitable for on-site assembly, and has high installation efficiency. It also saves transportation costs and reduces costs.
