Description

Fireproof rope clip for suspension bridge and manufacturing method thereof
Technical Field
The application relates to the technical field of fireproof protection of bridge cables, in particular to a fireproof cable clamp for a suspension bridge and a manufacturing method thereof.
Background
The suspension bridge is a bridge structure in which a bridge deck is suspended by a main rope, a rope clamp is positioned between the main rope and a bridge tower, and the rope clamp connects the main rope and the bridge tower together through a series of steel ropes, pull rods or other fastening devices so as to ensure the stability and the safety of the bridge. With the increase of traffic flow, the number of dangerous chemical tank cars for loading and transporting fuel, gas, explosion and chemical is increasing. Once unexpected fire disaster occurs in the dangerous chemical tank trucks, the energy released in a short time is huge, the temperature is extremely high, and the bridge structure is directly damaged, so that huge economic loss is caused. Investigation and research show that the tank truck has fire disaster, the temperature change path of the fire field flame space is very similar to the hydrocarbon fire disaster mode, the temperature of the tank truck is increased very fast, then the tank truck enters a high-temperature peak combustion period, and the whole combustion process is distributed exponentially.
The bridge cable with the expansion type sealing fireproof composite structure with the application number of CN202211191635.5 is disclosed in China at present, a flexible fireproof material (ceramic cotton felt, basalt fiber needled felt or aerogel felt) and an expansion flame-retardant sealing tape (formed by mutually superposing incombustible high-strength fiber cloth and expansion flame-retardant sealing glue) are used as main fireproof layers, and the expansion flame-retardant sealing tape which is made of high-strength fireproof flexible fiber materials and the superposition of the expansion flame-retardant sealing glue and the fireproof fiber cloth forms a synergistic fire-resistant structure and is used for preventing a main cable of a suspension bridge from fire, and the effect is good.
However, the cable clamp is not like a main cable, the shape of the cable clamp is abnormal, the size of the cable clamp on the main cable is not completely the same, the size of the cable clamp which is closer to two sides of the main cable is larger, and the surface of the cable clamp is uneven due to different shapes, so that cloth-like or felt-like structures such as basalt cloth are difficult to wrap like the surface of the main cable, and the construction is very inconvenient.

Through adopting above-mentioned technical scheme, carry out cladding seal to the junction of cable clamp and main rope through the round collar, carry out cladding to the junction of cable clamp and hoist cable through left side lower hem and right lower hem, the wearing degree of these two places is biggest relative cable clamp other parts, and basalt cloth can prevent wearing and tearing and the corruption on cable clamp surface as far as possible, extension cable clamp's life.
In summary, the present application includes at least one of the following beneficial technical effects:
1. the first basalt cloth is wrapped with the aerogel felt to prevent the aerogel felt from scattering, the second basalt cloth can form a protective layer with the first basalt cloth and high-temperature-resistant sealant therebetween, and the cable clamp surface is complex;
2. dividing the basalt cloth cover into three parts, namely a main cloth piece, a first end cloth piece and a second end cloth piece, respectively cutting the three parts from the basalt cloth, and then sewing. The basalt cloth sleeve manufactured in this way not only can save basalt cloth wound on the cable clamp, but also can make the surface of the cable clamp after cladding smoother so as to be connected with other layer structures;
3. the connecting part of the rope clamp and the main cable is coated and sealed through the round collar, the connecting part of the rope clamp and the sling is coated through the left lower hem and the right lower hem, the abrasion degree of the two parts is the largest relative to other parts of the rope clamp, and the basalt cloth can prevent the abrasion and corrosion of the surface of the rope clamp as much as possible, so that the service life of the rope clamp is prolonged.

Detailed Description
The application is described in further detail below with reference to fig. 1-7.
Example 1
The embodiment of the application discloses a fireproof rope clip for a suspension bridge. Referring to fig. 1 and 2, the fire-resistant cable clamp includes a cable clamp 1 and a fire-resistant structural layer covering a surface of the cable clamp 1.
The circumferential seam and the joint on the surface of the cable clamp 1 are subjected to anti-corrosion treatment, the anti-corrosion treatment is carried out according to the requirements of anti-corrosion coating technical conditions of a suspension bridge main cable system (JT/T694-2007), the circumferential seam and the joint of the cable clamp 1 are preferably coated in a sealing manner, namely, the circumferential seam and the joint are filled and sealed by non-vulcanized putty, and then, the surface is additionally provided with isolation cloth for isolation, so that the method is low in difficulty and easy to operate.
In addition, the fireproof structure layer sequentially comprises a first leveling layer 2, a heat insulation layer 3, a temperature control protective layer 4, a second leveling layer 5 and a protective layer 6 from inside to outside from the surface of the cable clamp 1.
The vulcanized rubber sealing layer is preferably selected for the first leveling layer 2, the thickness of the first leveling layer 2 is not less than 1mm, the vulcanized rubber sealing layer is coated on the surface of the cable clamp 1 after corrosion prevention, the outer connecting seam of the cable clamp 1 can be filled and sealed, and the surface of the cable clamp 1 is smoother, so that the thermal insulation layer 3 can be connected.
The insulation layer 3 is preferably an aerogel blanket layer, and the thickness of the aerogel blanket is preferably 10mm because the aerogel blanket has excellent insulation properties. Before the vulcanized rubber sealing layer of the first leveling layer 2 is not cured, the aerogel felt is coated on the vulcanized rubber sealing layer, so that the aerogel felt can be bonded with the first leveling layer 2, and phenomena such as bulge and the like of the aerogel felt during coating are reduced. However, since the aerogel blanket loses its insulation properties at high temperatures (e.g., over 650 ℃), the surface of the aerogel blanket must be temperature controlled to maintain the insulation of the aerogel blanket.
The temperature control protective layer 4 comprises a first layer of basalt cloth 41 coated on the aerogel felt layer, a high-temperature resistant sealant layer 42 coated on the surface of the first layer of basalt cloth 41, a second layer of basalt cloth 43 coated on the surface of the high-temperature resistant sealant layer 42, and an expansion type fireproof sealant layer 44 coated on the surface of the second layer of basalt cloth 43.
