Description

Technical Field

[0001] This utility model relates to the technical field of fireproof and heat-insulating materials for bridges, and in particular to a heat-insulating material for bridge suspension cables and main cables that is easy to fasten and install. Background Technology

[0002] As the core hub of modern transportation networks, bridges play an irreplaceable role in promoting regional economic development and ensuring the smooth operation of society. The number of long-span cable-stayed bridges in service and under construction in China is increasing. With the improvement of living standards, the number of various vehicles (trolleybuses, freight trucks, and hazardous materials transport vehicles) has been increasing year by year, leading to a rise in vehicle-related fires on bridges. This has gradually become a new type of hazard for long-span bridges, prompting fire prevention and insulation technology to become an important research direction in the field of bridge engineering.

[0003] As the main load-bearing system of modern bridges, steel structures face a significant risk of performance degradation in high-temperature environments. Steel suffers irreversible damage at 300℃, its strength decreases by 50% at 400℃, and it almost completely loses its load-bearing capacity at 600℃.

[0004] Existing bridge insulation materials are mainly divided into two types: one is a wrap-around insulation material composed of high-silica needle-punched felt and cloth, and the other is a spiral-wound insulation material composed of high-silica gel felt, cloth, and acrylic adhesive. Wrap-around insulation requires wire for fastening during installation and can be used on suspenders and main cables. However, in actual installation, the wire is often not perpendicular to the axis of the suspenders and main cables. Furthermore, the suspenders and main cables are prone to swaying under wind conditions. Over time, the wire will slowly move until it is perpendicular to the axis of the suspenders and main cables, at which point the fastening effect weakens, causing the wrap-around insulation to slip, fold, or even partially detach from the suspenders and main cables. Spiral-wound insulation, installed using a wrapping method, has a better fastening effect than wrap-around insulation, is less prone to slippage, and is easier to install. However, spiral-wound insulation has a certain thickness and relatively low flexibility, therefore it is only suitable for large-diameter main cables and cannot be used on smaller-diameter suspenders.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] See Figures 1-4 A heat insulation material for bridge suspension cables and main cables that is easy to fasten and install includes a heat insulation material body, which includes, from top to bottom, a hook and loop fastener 1, an upper fiber cloth 2, a middle fiber felt 3, a lower fiber cloth 4, and a hook and loop fastener 5.

[0027] Among them, the hook side 1 and the loop side 5 of the hook and loop fasteners work together to secure the main body of the heat insulation material after they are attached.

[0028] Regarding the preparation of the main body of the heat insulation material, as one embodiment, the hook and loop fastener 1, the upper fiber cloth 2, the middle fiber felt 3, the lower fiber cloth 4, and the hook and loop fastener 5 are sewn together with sewing thread. Each layer can be sewn together one by one with sewing thread, or all layers can be stacked and then sewn together with sewing thread at once.

[0029] The sewing thread can be one or more of the following: basalt fiber sewing thread, high silica fiber sewing thread, quartz fiber sewing thread, and glass fiber sewing thread. For multiple forms, multiple types of sewing thread can be used on a single thermal insulation material body. For example, a thermal insulation material may require multiple sewing threads, one of which is basalt fiber sewing thread, another is high silica fiber sewing thread, and so on. Alternatively, the sewing thread may be composed of multiple sewing threads in combination or wrapped together.

[0030] The upper fiber cloth 2 and the lower fiber cloth 4 are combinations of one or more of the following: basalt fiber cloth, high silica fiber cloth, quartz fiber cloth, and glass fiber cloth.

[0031] The upper fiber cloth 2 and the lower fiber cloth 4 can be of the same type or different types. For example, the upper fiber cloth 2 and the lower fiber cloth 4 can both be basalt fiber cloth, or the upper fiber cloth 2 can be basalt fiber cloth and the lower fiber cloth 4 can be high silica fiber cloth, and so on.

[0032] For a combination of multiple fiber fabrics, it can be composed of multiple types of fiber fabrics combined together, or it can be composed of multiple types of fiber fabrics assembled together, such as arranging multiple types of fiber fabrics in sequence and then sewing them together with sewing thread to form a single fiber fabric.

[0033] For the middle layer fiber felt 3, it is a composite felt composed of one or more of the following: basalt fiber needle-punched felt, basalt fiber aerogel felt, high silica fiber needle-punched felt, high silica fiber aerogel felt, quartz fiber needle-punched felt, quartz fiber aerogel felt, glass fiber needle-punched felt, and glass fiber aerogel felt.

[0034] In this embodiment, the arrangement of the hook and loop sides 1 and 5 can be varied:

[0035] Firstly, there is a full-coverage form, such as the hook and loop side 1 fully covering the surface of the upper fiber fabric 2; the loop and loop side 5 fully covering the surface of the lower fiber fabric 4.

[0036] Secondly, there are long strip-shaped forms, such as the hook and loop fastener 1 being set only on the long and / or short sides of the upper fiber fabric 2; and the loop fastener 5 being set only on the long and / or short sides of the lower fiber fabric 4, with the positions corresponding to the positions of the hook and loop fastener 1.

[0037] Both the hook and loop fastener 1 and the loop fastener 5 can be arranged in one of the following ways: the hook and loop fastener 1 can be arranged to cover the entire area, and the loop fastener 5 can be placed only on the long side of the lower fiber fabric 4; the hook and loop fastener 1 can be placed only on the long side of the upper fiber fabric 2, and the loop fastener 5 can be arranged to cover the entire area; the hook and loop fastener 1 can be arranged on one long side and one short side of the upper fiber fabric 2, and the loop fastener 5 can be arranged on one long side and one end of the lower fiber fabric 4, with the positions of the hook and loop fastener 1 and the loop fastener 5 corresponding to each other, and so on.

[0038] In this embodiment, the short side length of the thermal insulation material body is the perimeter of the main cable or sling 6 to be wrapped. That is, it is applicable not only to the main cable but also to the sling. The thermal insulation material body of the corresponding length can be set according to actual needs.

[0039] The form of setting hook and loop fastener 1 and hook and loop fastener 5 on the short side can also be applied to two adjacent thermal insulation material bodies. For example, the hook and loop fastener 1 set on the short side of one thermal insulation material body can cooperate with the hook and loop fastener 5 set on the short side of the adjacent thermal insulation material body to connect the two and fasten the thermal insulation material.

[0040] by Figure 2 , Figure 3 Taking the type shown as an example, during installation, the main body of the thermal insulation material is pressed tightly against the surface of the main cable or sling. The hook and loop fasteners 1 and 5 on the long side are then attached, while the loop fastener 5 on the short side is attached to the hook and loop fastener 1 on the short side of the adjacent thermal insulation material body, thus securing the thermal insulation material. Then, wire is wrapped around the surface of the thermal insulation material body to prevent the thermal insulation material from falling off due to aging of the hook and loop fasteners or failure caused by high temperatures during a fire.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
