Description

Technical Field

[0001] The present invention relates to the technical field of bridge cable fire protection, and more particularly to a cable fire-resistant jacket formed by bonding with H-type fire-proof mortar and a fire-proof structure thereof. Background Art

[0002] Bridge cables support and reinforce bridges and are one of the most critical load-bearing components of cable-type bridges. Accidents involving vehicles crossing the bridge, such as collisions with tanker trucks, buses, and cars, can easily cause fires. Such fires can cause significant damage to the entire bridge structure. Tanker truck fires, in particular, burn quickly, with high flame temperatures and strong radiation, reaching temperatures at the center of the flames as high as 1400°C. When heated to a certain temperature, bridge cables experience a significant loss of strength and hardness, while their plasticity increases significantly, causing cable deformation and even bridge collapse. Failure of bridge cables can trigger multiple disasters, resulting in significant safety incidents and economic losses.

[0003] Generally, cables will not be significantly affected by temperature until their tensile strength is below 300°C. It takes at least 30 minutes from the time a fire breaks out on a bridge for firefighters to arrive at the scene, so fire protection of the cables is essential.

[0004] Fire protection for existing bridge cables is no longer a technical challenge, and the selection of materials and construction methods fully meet fire protection requirements. However, the existing problem is that the construction of the fireproof layer is generally cumbersome. To overcome this problem, some assembled fireproof structures are used in the existing technology. However, these structures often have uneven surfaces due to splicing connections, and it is difficult to ensure the structural strength of the spliced ​​structure.

[0005] Therefore, how to provide a cable fire-resistant jacket and its fire-proof structure with high structural strength and smooth outer surface connection is a problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0006] In view of this, the present invention provides a cable fire-resistant jacket and a fire-resistant structure thereof formed by bonding with H-type fire-resistant mortar, aiming to solve the above-mentioned technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A fire-resistant jacket for a cable formed by bonding with an H-type fire-resistant mortar, comprising: a fire-resistant tube and an H-type adhesive strip;

[0009] The fireproof tube is formed with a bonding fracture along the axial direction; the cross section of the H-shaped bonding strip is H-shaped, and the two side openings of the H-shaped bonding strip are plugged into and bonded to the two side edges of the bonding fracture.

[0010] Through the above technical solution, the present invention adopts an H-shaped adhesive strip to achieve the docking of the bonding fracture of the fire tube. The H-shaped adhesive strip uses its structural advantages to clamp the edge of the bonding fracture of the fire tube. The stability of bonding in the clamping state is stronger and the bonding effect is better. At the same time, because the H-shaped adhesive strip avoids the traditional clip-on structure, it forms an outer surface structure with a flat surface in the simplest way.

[0011] Preferably, in the above-mentioned fire-resistant jacket of the cable formed by bonding with H-type fire-proof glue, the H-type adhesive strip includes a first splicing strip and a second splicing strip; the first splicing strip forms two first convex strips along the axial direction, and the two first convex strips form a linear splicing interface; the second splicing strip forms a second convex strip along the axial direction, and the second convex strip is inserted into the linear splicing interface and bonded and fixed to the linear splicing interface. The present invention designs the H-type adhesive strip as a split structure in which the first splicing strip and the second splicing strip are bonded. The advantage of the split structure is that during the splicing process of the first splicing strip and the second splicing strip, the edge of the fire-proof tube bonded fracture can be bonded and clamped to the inner side of the H-mouth formed by it, which can reduce the dimensional accuracy of the H-type fire-proof glue processing and prevent the inconvenience of plugging in, improper plugging in, and unevenness caused by gluing on the inside.

[0012] Preferably, in the aforementioned fire-resistant cable jacket formed by bonding with H-shaped fire-resistant mortar, the raised height of the second protrusion is less than the depth of the linear splicing joint. This depth gap provides adjustable space for assembly of the first and second splicing strips, allowing for adaptive bonding and fixing according to the thickness of the fire-resistant tube.

[0013] Preferably, in the aforementioned cable fire-resistant jacket formed by bonding with an H-shaped fire-resistant mortar, the H-shaped adhesive strip is made of fire-resistant mortar. The H-shaped adhesive strip is made of fire-resistant mortar in a mold and demolded. Since the adhesive bonding during on-site construction requires time for the gluing and solidification, it will prolong the construction period. However, the H-shaped adhesive strip of the present invention can achieve rapid fixation by utilizing a snap-fit ​​and bonding structure, thus being free from the limitation of solidification time and allowing for rapid construction.

[0014] Preferably, in the above-mentioned cable fireproof jacket formed by bonding with H-shaped fireproof mortar, the fireproof tube is composed of multiple layers of basalt fiber and fireproof mortar. The structure of the fireproof tube can be made of existing fireproof materials, which is not the focus of the present invention and will not be described in detail here.

[0015] The present invention also provides a fireproof structure of a cable fireproof jacket formed by bonding with H-type fireproof putty, wherein multiple cable fireproof jackets formed by bonding with H-type fireproof putty are sequentially mounted on the cable; two adjacent fireproof tubes are bonded and fixed by an H-type adhesive ring, the cross-section of the H-type adhesive ring is H-shaped, and the openings on both sides of the H-type adhesive ring are plugged into and bonded to the ends of the two adjacent fireproof tubes; the H-type adhesive ring has an avoidance fracture for avoiding the H-type adhesive strip.

[0016] Through the above technical solution, the fireproof structure provided by the present invention not only bonds and fixes the fireproof tubes with H-shaped adhesive strips, but also bonds and fixes the two fireproof tubes with an annular H-shaped adhesive ring, so that it has the same effect, which can not only promote the construction progress, but also ensure the structural strength of the connection and the smoothness of the outer surface.

[0017] It should be noted here that, in theory, the H-shaped adhesive strip and the H-shaped adhesive ring will have a certain protrusion relative to the surface after bonding. However, in actual use, the thickness of the H-shaped adhesive strip and the H-shaped adhesive ring is actually very thin. The thickness of the single board generally does not exceed 2 mm. This thickness can meet the flatness requirements of the outer side of the cable. In addition, a layer of fire retardant paint (optional) and a decorative paint layer will be applied after bonding, so that the effect after leveling tends to be smooth.

[0018] Preferably, in the above-mentioned fireproof structure of the cable fire-resistant jacket formed by bonding with H-type fireproof putty, the H-type adhesive strip includes a first splicing strip and a second splicing strip; the first splicing strip forms two first convex strips along the axial direction, and the two first convex strips form a linear splicing interface; the second splicing strip forms a second convex strip along the axial direction, and the second convex strip is inserted into the linear splicing interface and bonded and fixed to the linear splicing interface.

[0019] Preferably, in the above-mentioned fireproof structure of the cable fire-resistant jacket formed by bonding with H-type fireproof putty, the H-type bonding ring includes a first splicing ring and a second splicing ring; the first splicing ring forms two first convex rings radially outward, and the two first convex rings form an annular splicing interface; the second splicing ring forms a second convex ring radially inward, and the second convex ring is inserted into the annular splicing interface and bonded and fixed to the annular splicing interface.

[0020] In the present invention, the H-shaped adhesive strip and the H-shaped adhesive ring are both split structures, so that positioning can be performed by one part of the split structure and then bonding can be performed by the other part. This is more advantageous during installation and can also ensure the stability of assembly bonding.

[0021] Preferably, in the above-mentioned fireproof structure of the cable fireproof jacket formed by bonding with H-type fireproof mortar, the first splicing strip is first bonded and fixed to the cable according to the position of the bonding fracture of the fireproof tube, and then the first splicing ring is bonded to the cable below the first splicing strip; one of the fireproof tubes is bonded to the outside of the cable, and its edge is bonded and fixed to the first splicing strip and the first splicing ring, and the first splicing strip and the first splicing ring are bonded downward in sequence, and then the fireproof tube is bonded; finally, the second splicing strip is plugged and bonded to the first splicing strip, and the second splicing ring is plugged and bonded to the first splicing ring, and the bonding and fixing to the edge of the fireproof tube are completed. The bonding method of the present invention can take advantage of the separation of the H-type adhesive strip and the H-type adhesive ring, first positioning, and then bonding and fixing, making bonding more convenient and more stable.

[0022] Preferably, in the aforementioned fireproof structure of a cable fireproof jacket formed by bonding with an H-shaped fireproof mortar, the second splicing strips are staggered and spliced ​​with the first splicing strips on the plurality of interconnected fireproof tube structures. The staggered splicing and bonding of the second splicing strips with the first splicing strips can improve the connection strength between adjacent fireproof tubes, further optimize the bonding effect, and enhance the integrity of the connection by staggering the gaps.

[0023] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses a cable fire-resistant jacket and a fire-resistant structure thereof formed by bonding with an H-type fire-resistant mortar, which has the following beneficial effects:

[0024] 1. The present invention adopts fireproof mortar to make H-shaped connection structure, and can utilize plug-in and bonding structure to directly bond the fireproof tube of fracture. This bonding and plug-in form has strong stability, and because the structure made of fireproof mortar is relatively thin, its appearance is relatively flat, and it is easy to carry out subsequent gluing construction.

[0025] 2. The split H-shaped fireproof mortar connection structure designed in the present invention can overcome the dimensional error in the bonding of the fireproof mortar and further improve the stability of the structure.

[0026] 3. The present invention facilitates construction through the split H-type fireproof mortar connection structure, allows for step-by-step construction operations, and ensures the sealing and structural strength of each layer of bonding.

[0027] 4. The H-type fireproof mortar connection structure of the present invention adopts a staggered bonding form, which can form a stronger structural connection between the fireproof tubes and achieve stability after the overall structure is connected. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0060] Example 1:

[0061] See attached Figure 1 To the attached Figure 6 , the embodiment of the present invention discloses a cable fire-resistant jacket formed by bonding with an H-type fire-resistant mortar, comprising: a fire-resistant tube 1 and an H-type adhesive strip 2;

[0062] The fireproof tube 1 is formed with a bonding fracture 11 along the axial direction; the cross section of the H-shaped bonding strip 2 is H-shaped, and the openings on both sides of the H-shaped bonding strip 2 are plugged into and bonded to the edges on both sides of the bonding fracture 11.

[0063] In order to further optimize the above technical solution, the H-shaped adhesive strip 2 is made of fireproof putty.

[0064] In order to further optimize the above technical solution, the fireproof tube 1 is composed of multiple layers of basalt fiber and fireproof putty bonded together.

[0065] During assembly, it is only necessary to apply glue to the two edges of the fireproof tube 1 with the bonding fracture 11 and insert the fireproof tube 1 into the openings on both sides of the H-shaped adhesive strip 2 for bonding and fixing.

[0066] Example 2:

[0067] See attached Figure 1 To the attached Figure 7 and attached Figure 11 An embodiment of the present invention discloses a fireproof structure of a cable fireproof jacket formed by bonding with an H-type fireproof putty, wherein one of the cable fireproof jackets formed by bonding with an H-type fireproof putty in multiple embodiments 1 is sequentially mounted on a cable 3; two adjacent fireproof tubes 1 are bonded and fixed by an H-type adhesive ring 4, the cross-section of the H-type adhesive ring 4 is H-shaped, and the openings on both sides of the H-type adhesive ring 4 are plugged and bonded with the ends of the two adjacent fireproof tubes 1; the H-type adhesive ring 4 has an avoidance fracture 41 for avoiding the H-type adhesive strip 2.

[0068] The construction method of the fireproof structure provided in this embodiment is as follows:

[0069] Step 1: See attached Figure 8 First, the fireproof tube 1 is sequentially installed on the outside of the cable 3.

[0070] Step 2: See attached Figure 9 , then use the two adjacent fire tubes 1 Figure 7 The H-shaped bonding ring 4 is plugged and bonded.

[0071] Step 3: See attached Figure 10 Then gently pry open the bonding fracture 11 on the fireproof tube 1, insert the H-shaped adhesive strip 2 inside the bonding fracture 11, so that the two side openings of the H-shaped adhesive strip 2 are plugged into and bonded to the two side edges of the bonding fracture 11.

[0072] Step 4: See attached Figure 11 , install the H-shaped adhesive ring 4 and the H-shaped adhesive strip 2 one by one. In this embodiment, in order to improve the stability of the connection between the fire tubes 1, the H-shaped adhesive strip 2 and the fire tube 1 are staggered and inserted and bonded.

[0073] Example 3:

[0074] See attached Figure 12 To the attached Figure 16 The difference between this embodiment and embodiment 1 is that:

[0075] The H-shaped adhesive strip 2 includes a first splicing strip 21 and a second splicing strip 22; the first splicing strip 21 forms two first convex strips 211 along the axial direction, and the two first convex strips 211 form a linear splicing interface 212; the second splicing strip 22 forms a second convex strip 221 along the axial direction, and the second convex strip 211 is inserted into the linear splicing interface 212 and bonded and fixed to the linear splicing interface 212.

[0076] In order to further optimize the above technical solution, the protrusion height of the second protrusion 221 is smaller than the depth of the linear joint 212 .

[0077] During assembly of this embodiment, there is no need to perform plug-in. Instead, glue is applied to the two edges of the fire tube 1 with the bonding fracture 11, and then the bonding fracture 11 of the fire tube 1 is clamped by combining the first splicing strip 21 and the second splicing strip 22, which is equivalent to the plug-in and bonding in Example 1. This connection method has higher precision and better stability.

[0078] Example 4:

[0079] See attached Figure 12 To the attached Figure 17 and attached Figure 22 The difference between the fireproof structure formed in this embodiment and that in embodiment 2 is that:

[0082] In order to further optimize the above technical solution, the protrusion height of the second protrusion 221 is smaller than the depth of the linear joint 212 .

[0084] Step 1: See attached Figure 18 First, the first splicing strip 21 is bonded and fixed to the cable 3 according to the position of the bonding break 11 of the fireproof tube 1.

[0085] Step 2: See attached Figure 19 , and then bond the first splicing ring 42 to the cable 3 below the first splicing strip 21.

[0086] Step 3: See attached Figure 20 , bond a fireproof tube 1 to the outside of the cable 3, and bond its edge to the first splicing strip 21 and the first splicing ring 42, and bond the first splicing strip 21 and the first splicing ring 42 downward in sequence, and then bond the fireproof tube 1.

[0087] Step 4: See attached Figure 21 Finally, the second splicing strip 22 is plugged and bonded to the first splicing strip 21 .
