[0033] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0034] In the related art, when control cables and power cables exist on the cable support at the same time, fireproof isolation measures must be taken. Taking the cables laid in the cable trench as an example, the current conventional scheme includes:

[0035] During the cable laying stage, the fireproof plate is made into a drawer shape by using metal iron sheet as support and reinforcement to realize the fireproof separation between layers. Although this process has an attractive appearance, the fireproof plate drawer can be inserted and extracted for easy maintenance and expansion, but its installation and construction are difficult, labor-intensive and material-intensive, and the overall cost performance is not high.

[0036] The fireproof plate is improved into an L-shaped fireproof plate formed at one time, which is placed on the cable support. The holes between each plate are connected by connecting pieces and bolts. Since the fireproof plate is a brittle material, it can be broken into waste products if not careful during drilling. There is a large gap at the connection between the two fireproof plates, which poses a risk of fire spread.

[0037] Both of the above cable laying schemes have major defects. The former has a high cost, and the latter has poor fireproof effect, which poses a major safety hazard.

[0038] The technical solution of the present application is improved based on the above cable laying scheme. Specifically, the gap is covered by the connecting plate, so that the fire does not easily spread from the gap position on the cable support, and the beneficial effect of better fireproof performance is achieved.

[0039] Figure 1 is a structural schematic diagram of a cable support provided by an embodiment of the present application, Figure 2 is a partial structural schematic diagram of a cable support installed on a wall surface provided by an embodiment of the present application, Figure 3 is a structural schematic diagram of a connecting plate provided by an embodiment of the present application, Figure 4 is a structural schematic diagram of a bracket provided by an embodiment of the present application, Figure 5 is a front structural schematic diagram of a bracket provided by an embodiment of the present application, Figure 6 is a top structural schematic diagram of a bracket provided by an embodiment of the present application, Figure 7 is a side structural schematic diagram of a bracket provided by an embodiment of the present application, Figure 8 is a structural schematic diagram of a bracket provided by an embodiment of the present application, in which a second accommodating slot is formed at a position of a positioning pin.

[0040] To solve the above technical problems, please refer to Figures 1-8 The first aspect of the present application proposes a cable support (not shown in the drawings) with the beneficial effect that the cable support is not prone to fire spreading from the gap position, and has better fireproof performance.

[0041] Referring to Figures 1-8 In some embodiments of the present application, the cable support includes a support assembly 100, a fireproof partition plate 200, and a connecting plate 300. The support assembly 100 is installed on a wall surface 400 where the cable is to be installed, and at least two support assemblies 100 are arranged at intervals on the wall surface 400. The fireproof partition plate 200 is connected with the support assembly 100, and the fireproof partition plate 200 is between the two adjacent support assemblies 100. The side of the fireproof partition plate 200 away from the wall surface 400 extends upward and forms an extension 220, and the gap is between the two adjacent extensions 220. The connecting plate 300 connects the two adjacent extensions 220, and the connecting plate 300 covers the gap.

[0042] Based on the above embodiments of the present application, the support assembly 100 can support the cable, and the weight of the cable itself is mainly supported by the support assembly 100. The fireproof partition plate 200 can prevent fire from spreading, slow down the spread of fire, reduce the difficulty of fire fighting, and reduce the loss of disaster. Since there is a gap between the two adjacent extensions 220 of the fireproof partition plate 200, there is a risk of fire spreading and expanding at the gap position. By covering and blocking the gap with the connecting plate 300, the possibility of fire spreading from the gap position can be reduced or even avoided, further slowing down the spread of fire. The embodiments of the present application have the beneficial effect that the cable support is not prone to fire spreading from the gap position, and has better fireproof performance.

[0043] It should be noted that the wall surface 400 described above can be the wall surface 400 of the cable trench, which is excavated and built according to design requirements, the side wall of the trench is welded with a load-bearing angle steel frame (equivalent to the column 130 described below) and grounded as required, and the upper surface is covered with a cover plate. The purpose of the cable trench is to provide a special underground channel for laying cables. The cable trench has two oppositely arranged wall surfaces 400. The support assembly 100 described above can be installed on a single wall surface 400 in the cable trench as needed, or the support assembly 100 described above can be installed on both wall surfaces 400.

[0044] The wall surface 400 described above can also be the wall surface 400 of a common wall, such as the wall surface 400 inside or outside a residential building, or the wall surface 400 inside or outside a factory building. The support assembly 100 can be installed on the corresponding wall surface 400 as needed to support and install the cable and the fireproof partition 200.

[0045] It should be noted that each wall surface 400 can be provided with at least one layer of support assembly 100, and each layer of support assembly 100 can include at least two support assemblies 100 arranged at intervals. Each layer of support assembly 100 can be linearly arranged according to the arrangement direction of the cable. The arrangement mode can be linear or curved. The linear arrangement mode can be horizontal linear arrangement mode or inclined linear arrangement mode. When the arrangement position of the cable needs to be raised, lowered, or turned, the support assembly 100 can be arranged according to the appropriate linear mode.

[0046] The above describes the arrangement mode of at least two support assemblies 100 in a single layer. The arrangement mode of multiple layers of support assemblies 100 is similar to that of a single support assembly 100. The arrangement mode of support assemblies 100 in different layers can be completely consistent, with only the height being different. Alternatively, the support assemblies 100 in different layers can be arranged in different ways as needed, for example, the first layer of support assemblies 100 is arranged in a linear manner, and the second layer of support assemblies 100 is arranged in a curved manner. The accompanying drawings of the present application exemplarily embody an embodiment in which the arrangement modes of support assemblies 100 in different layers are completely consistent, with only the height being different. See the accompanying drawings Figure 1 The accompanying drawings show an embodiment in which the cable support has four layers of support assemblies 100.

[0047] It should be noted that the support assembly 100 of the present application can be directly installed on the wall surface 400. The installation can be achieved by fixed connection, magnetic attraction, clamping, welding, etc. In the fixed connection, the fixed part can be a general bolt, expansion bolt, etc. to fix the support assembly 100 to the corresponding wall surface 400. The above installation methods can reduce the installation cost of the cable support.

[0048] The support assembly 100 of the present application can also be installed on the stand 130 first, and then fixed on the corresponding wall surface 400 through the stand 130. The installation stability of the cable support to the cable and the fireproof partition plate 200 can be improved through the arrangement of the stand 130. And the grounding can be performed through the stand 130.

[0049] Referring to Figures 1 to 3 In some embodiments of the present application, the connecting plate 300 comprises a hanging part 310 and a covering part 320. The hanging part 310 has a downwardly open hanging groove 311, and the hanging part 310 is hung on the extension part 220. The covering part 320 is connected with the hanging part 310 and is arranged on the side of the extension part 220 away from the wall surface 400. The covering part 320 extends to the bottom of the extension part 220, and the covering part 320 can cover the side of the gap away from the wall surface 400.

[0050] Based on the above-mentioned embodiments of the present application, the hanging part 310 can facilitate the hanging of the entire connecting plate 300, and the covering part 320 can cover the gap. After covering and plugging the gap, the possibility of fire spreading from the gap position can be reduced or even avoided, the spread of fire can be further slowed down, and the fire risk can be reduced.

[0051] Further, the connecting plate further comprises a limiting part 330. The limiting part 330 is connected with the covering part 320, and the limiting part 330 is arranged below the fireproof partition plate 200 and extends towards the wall surface 400. The limiting part 330, the covering part 320 and the hanging part 310 cooperate to form a limiting cavity accommodating the extension part.

[0052] Based on the above-mentioned embodiments of the present application, the limiting part 330 can improve the connection stability of the connecting plate 300 and reduce the possibility of accidental falling of the connecting plate 300. After the cooperation of the above-mentioned hanging part 310, covering part 320 and limiting part 330, the freedom of the connecting plate 300 and the fireproof partition plate 200 can only be left relative sliding under the action of the limiting cavity. When assembling the connecting plate 300, the connecting plate 300 can be installed in the form of relative sliding. When the connecting plate 300 has relatively large elasticity, the hanging groove 311 can be hung on the top of the extension part 220 first, and then installed by pressing.

[0053] It should be noted that the shape of the hanging groove 311 is matched with the top shape of the extension part 220. The top shape of the extension part 220 can be a prism upper end surface shape or an arc shape such as a circular arc, and the shape of the hanging groove 311 is adaptively adjusted according to the top shape of the extension part 220. The size of the hanging groove 311 is slightly larger than the top end of the extension part 220, and the maximum gap between the inner wall of the hanging groove 311 and the extension part 220 after hanging is less than a preset value. The preset value varies according to the size of the fireproof partition 200, and the preset value can be controlled to be 0.1-3 mm, and can also be 1 mm, 2 mm, etc. That is, the hanging groove 311 can have high stability and is not easy to fail, and can also ensure that the hanging groove 311 has a certain sliding space.

[0054] It should be noted that the connecting plate 300 can be made of a metal material, specifically an iron plate, a stainless steel plate, a copper plate, an aluminum plate, an aluminum alloy plate, etc. It can also be made of a non-metallic material that is fireproof, or a composite material made of a mixture of multiple materials. The overall structure of the connecting plate can be a structure similar to a C-shaped groove.

[0055] Referring to Figure 2 In some embodiments of the present application, the limiting part 330 is provided with a first positioning part, and the support assembly 100 is provided with a second positioning part matched with the first positioning part. One of the first positioning part and the second positioning part is a positioning hole 331, and the other is a positioning pin 123.

[0056] Based on the above-mentioned embodiments of the present application, the first positioning part and the second positioning part are cooperatively arranged, and the connecting plate 300 can be further limited by the mutual adaptation of the first positioning part and the second positioning part, so as to lock the position of the connecting plate 300. The first positioning part can be a positioning hole 331, and the second positioning part can be a positioning pin 123, which realizes positioning through pin hole cooperation. The first positioning part can also be a positioning pin 123, and the second positioning part can be a positioning hole 331 according to needs.

[0057] It should be noted that the first positioning part and the second positioning part can also be positioned in other ways, such as one of the first positioning part and the second positioning part being a clamping edge and the other being a buckle, which realizes positioning through cooperation of the clamping edge and the buckle.

[0058] In some embodiments of the present application, the first positioning part is a positioning hole 331, and the second positioning part is a positioning pin 123, which is adjustably installed on the support assembly 100.

[0059] Based on the above embodiments of the present application, the first positioning part is set as the positioning hole 331, which can reduce the processing difficulty of the connecting plate 300 and improve the processing efficiency of the connecting plate 300. The positioning pin 123 can cooperate with the positioning hole 331 to realize the positioning and locking of the connecting plate 300.

[0060] Further, the positioning pin 123 can be set as a telescopic pin as needed, and specifically, the positioning pin 123 can be provided with certain hiding and resetting capabilities by cooperating with an elastic member, so that the assembly space can be saved. When the positioning pin 123 is moved to a position matched with the positioning hole 331, the positioning pin 123 is elastically inserted into the positioning hole 331 to realize positioning.

[0061] In some embodiments of the present application, the support assembly 100 includes a support arm 110 and a bracket 120. The support arm 110 is directly or indirectly mounted on the wall 400 and can support the cable. The bracket 120 is arranged below the support arm 110 and is detachably connected with the support arm 110 or integrally arranged. The bracket 120 can support the fireproof partition 200 and part of the connecting plate 300. The bracket 120 cooperates with the support arm 110 to form a mounting groove 140, and the fireproof partition 200 is partially mounted in the mounting groove 140.

[0062] Based on the above embodiments of the present application, the support arm 110 is used to support the cable. The cable can be a signal cable (control cable) or a power cable (power cable). The support arm 110 can also support the signal cable and the power cable as needed. The support arm 110 can be directly fixed on the wall, or can be fixed on the stand first, and then the stand is fixed on the wall. If necessary, the stand or the corresponding bracket can be erected on the ground or embedded in the ground to realize installation. The bracket 120 is used to support the fireproof partition 200. The fireproof partition 200 is specifically supported on the bracket 120. The bracket 120 and the support arm 110 at least partially have a gap and cooperate to form a mounting groove 140. The fireproof partition 200 is partially mounted in the mounting groove 140.

[0063] It should be noted that the support arm 110 can be integrally arranged with the bracket 120, and can be integrally formed by casting, powder metallurgy, 3D printing, etc. The support arm 110 and the bracket 120 can also be detachably connected together. Such arrangement is more conducive to the assembly of the fireproof partition 200 and the connecting plate 300. The support arm 110 and the bracket 120 can be detachably connected by at least one of magnetic attraction, pin hole, bolt connection, clamping, etc. If necessary, they can also be fixedly connected by welding, etc.

[0064] It should be noted that the positioning pin 123 can be arranged on the support arm 110 of the support assembly 100 as needed, or the positioning pin 123 can be arranged on the bracket 120 of the support assembly 100.

[0065] In some embodiments of the present application, the support arm 110 includes a support plate 111 and a reinforcing plate 112 arranged below the support plate 111, and the bracket 120 is detachably mounted on the reinforcing plate 112.

[0066] The bracket 120 includes a support portion 121 and a mounting portion 122. The support portion 121 is arranged spaced apart from the support plate 111 and forms a mounting groove 140, and part of the connecting plate 300 is located in the mounting groove 140. The mounting portion 122 is connected with the support portion 121 and is located below the support portion 121. The mounting portion 122 is detachably connected with the reinforcing plate 112.

[0067] Based on the above-mentioned embodiments of the present application, the support plate 111 is the main carrier of the support arm 110 for supporting the cable, and the reinforcing plate 112 can improve the supporting performance of the support plate 111 and can mount the bracket 120 on the reinforcing plate 112. The reinforcing plate 112 and the support plate 111 are arranged at an angle, which further allows the reinforcing plate 112 to be arranged perpendicular to the plane in which the support plate 111 is located. The bracket 120 can support the fireproof partition 200, specifically through the support portion 121 to support the fireproof partition 200, and the mounting portion 122 can mount the entire bracket 120 on the reinforcing plate 112.

[0068] Further, the support plate 111 can be provided with weight-reducing holes, reinforcing ribs, etc. on it as needed. The weight-reducing holes can reduce the weight of the support plate 111, reduce the amount of material used, and reduce costs. The reinforcing ribs can improve the supporting capacity of the support plate 111 without increasing the weight. The arrangement and reinforcing position of the reinforcing ribs can be adaptively adjusted according to the stress analysis of the cable. Reinforcing ribs and other structures can also be arranged on the bracket 120 as needed.

[0069] It should be noted that the reinforcing plate 112 and the mounting portion 122 can be connected by at least one of magnetic attraction, pin hole, bolt connection, clamping, etc. If necessary, they can also be fixedly connected by welding, etc. Taking bolt connection as an example, at least one first mounting hole 1121 is formed on the reinforcing plate 112, and at least one second mounting hole 1221 is formed on the mounting portion 122. The first mounting hole 1121 and the second mounting hole 1221 are adapted to and correspond to each other. The bolt can be inserted through the first mounting hole 1121 and the second mounting hole 1221 at the same time, and fixed by a nut. One of the first mounting hole 1121 and the second mounting hole 1221 can be provided as a threaded hole as needed, and the threaded hole is matched with the bolt to reduce the use of nuts, thereby reducing the number of parts and reducing costs.

[0070] When two installation portions 122 are provided, each first installation hole 1121 corresponds to two second installation holes 1221, a bolt can be simultaneously passed through the first installation hole 1121 and the two second installation holes 1221, and fixed by a nut, one of the first installation hole 1121 and the two second installation holes 1221 can be provided as a threaded hole according to the need, and the threaded hole is matched with the bolt to reduce the use of the nut. The embodiment in which the first installation hole 1121 and the second installation hole 1221 are provided with two groups is exemplarily embodied in the drawings of the present application, and the specific reference is made to Figure 2 .

The second accommodation groove 1212 can accommodate the connecting plate 300, reduce the gap between the fireproof partition 200 and the supporting portion 121, improve the contact area of the fireproof partition 200 and the supporting portion 121, and make the supporting of the supporting portion 121 more stable and reliable, and the specific reference is made to the second accommodation groove 1212 in Figure 8 .

[0073] In some embodiments of the present application, the connecting plate 300 partially abuts against the supporting portion 121, and the abutting portion is provided with a positioning hole 331; the abutting portion of the supporting portion 121 and the connecting plate 300 is provided with a positioning pin 123 matched with the positioning hole 331; wherein the positioning pin 123 is movably connected with the supporting portion 121, and the bottom of the positioning pin 123 is provided with an elastic member.

[0074] Based on the above-mentioned embodiments of the present application, the above-mentioned structure can realize the installation and positioning of the connecting plate 300 through the cooperation of the positioning hole 331 and the positioning pin 123. After the positioning hole 331 is arranged on the connecting plate 300, the processing difficulty of the connecting plate 300 can be reduced, and the processing efficiency of the connecting plate 300 can be improved.
