Description

Technical Field

[0001] This invention relates to the field of fireproof covers for bridge anchor cups, and particularly to a fireproof cover for the anchor cup portion of a cable-stayed bridge and its preparation method. Background Technology

[0002] Bridges, serving as vital links between regions, are a crucial component in promoting economic development and national defense. To improve regional transportation and promote coordinated regional development, my country has constructed hundreds of thousands of highway and railway bridges in recent years. For long-span bridges crossing major rivers, oceans, and canyons, cables are the primary load-bearing components, including cable-stayed bridges, suspension bridges, and arch bridges. The cable anchor is a key load-bearing component in cable-stayed bridge systems, connecting the beams and cables and effectively transferring the beam load to the cables. Its structural safety directly affects the overall safety of the bridge.

[0003] The characteristic of bridge upset anchors is that the anchor cup has radial grooves, the end of the steel wire is embedded in the groove of the anchor cup, the anchor cup is fitted inside the connecting sleeve, and the connecting sleeve is fitted with an anchoring nut. The connecting sleeve is a double-threaded tube. It consists of a trumpet tube, connecting sleeve, anchor plate, spiral reinforcement, steel wire, anchoring nut, and anchor cup. The new type of bridge upset anchor has good steel wire anchoring performance, is easy to construct, can shorten the construction period, and improve work efficiency. It is manufactured in the factory, avoiding the upset and wire threading work on the construction site, and also avoiding the complicated procedures of opening and groove leaving in the formwork when making concrete structures.

[0004] In existing fireproof covers for anchor cup surfaces, halogenated flame retardants, while possessing good flame retardancy, release large amounts of smoke and toxic, corrosive gases during combustion. They also lack rapid expansion and carbonization effects and have higher thermal conductivity compared to expandable flame retardants. Fireproof cover material is typically cut manually and then bonded to the anchor cup surface for fire and heat protection. This process requires manual measurement of the anchor cup's usable area and manual cutting of the fireproof cover material. Furthermore, the fireproof covers carried by construction workers are usually quite bulky, making them inconvenient to carry and cut. Due to the anchor cup's unique location, construction becomes difficult, unsafe, and slow, hindering timely application of the fireproof cover to the anchor cup surface. Therefore, this application provides a fireproof cover for the anchor cup portion of a cable-stayed bridge and its preparation method to meet this requirement. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a fireproof cover for the anchor cup portion of a cable-stayed bridge and its preparation method. This solves the problems of existing fireproof covers being unable to expand and carbonize quickly to provide a dense fire-blocking effect and reduce the thermal conductivity, as well as the inconvenience of fitting anchor cups at different locations and the slow construction speed, making it impossible to fit the fireproof cover in a timely manner.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0011] The mixture is prepared by mixing 3 parts ammonium phosphate, 1 part pentaerythritol, 1 part urea, 2 parts melamine formaldehyde, and 1 part phosphorus pentasulfide.

[0012] The mixture is further mixed at high speed with 0.5 parts of talc and 10 parts of epoxy resin, and then extruded using an extrusion device. The mixture is then granulated at a temperature of 180-200°C to produce mixed particles, thereby obtaining a foamed fireproof layer.

[0013] One side of the foamed fireproof layer is coated with a fluorocarbon topcoat.

[0014] Preferably, a material drawer is inserted into one side of the equipment base plate, a compression spring is inserted into the inside of the material drawer, a positioning plate is inserted into the inside of the compression spring, a rotating shaft is sleeved on the outer surface of the upper side of the positioning plate, and epoxy resin is sleeved on the outer surface of the rotating shaft.

[0015] Preferably, a length control motor is inserted into the upper surface of the material drawer, a measuring cylinder is inserted inside the length control motor, and a positioning telescopic plate is sleeved on the outer surface of the measuring cylinder. A cutting motor is inserted into the upper surface of the equipment base plate, a cutting gear is inserted inside the cutting motor, a blade is slidably connected inside the equipment base plate, an extrusion motor is snapped into the inner side of the equipment base plate, an extrusion threaded column is inserted inside the extrusion motor, an extrusion column is sleeved on the outer surface of the extrusion threaded column, an opening and closing gear is inserted into the upper surface of the equipment base plate, an opening and closing motor is sleeved on the outer surface of the opening and closing gear, an opening and closing plate is inserted into the inside of the equipment base plate, an angle shaft is inserted into the inside of the opening and closing plate, a crescent frame is sleeved on the outer surface of the angle shaft, a cover plate is snapped into the upper surface of the equipment base plate, a retaining ring is provided on the upper surface of the cover plate, a small driver is inserted into the inside of the cover plate, a small battery is inserted into one side of the equipment base plate, and a fixing hook is inserted into the inside of the retaining ring.

[0016] Preferably, a fixing block is inserted into the upper surface of the fixing hook, a support plate is sleeved on the outer surface of the fixing hook, a control shaft is inserted into the upper surface of the fixing hook, a control motor is sleeved on the outer surface of the control shaft, a lifting cylinder is provided on the lower surface of the support plate, and a connecting column is sleeved on the outer surface of the lifting cylinder.

[0017] Preferably, a lifting motor is inserted inside the connecting column, and a lifting threaded column is inserted inside the lifting motor.

[0018] Preferably, the lower surface of the connecting column is provided with a rotating gear, the outer surface of the connecting column is fitted with a movable housing, and the upper surface of the movable housing is inserted with a drive motor.

[0019] Preferably, a drive gear is inserted inside the drive motor, a mobile motor is snapped into the inside of the movable housing, a mobile gear is inserted inside the mobile motor, and the rotating gear meshes with the drive gear.

[0021] A fireproof cover for the anchor cup portion of a cable-stayed bridge and its preparation method include the following steps:

[0022] Step 1: First, pull out the material drawer, then install the fireproof cover material on the rotating shaft, and then insert the material drawer into the equipment base plate. When it is possible for manual construction, the construction personnel can manually pull out the fixing block and remove the equipment base plate, and then carry the equipment base plate forward for construction.

[0023] Step 2: Control the opening and closing plate to move outward by rotating the opening and closing gear through the opening and closing motor. When the opening and closing plate reaches its limit length, the crescent frame can be controlled by the angle axis to wrap around the anchor cup. The opening and closing plate is then contracted inward by rotating the opening and closing gear through the opening and closing motor to completely wrap around the anchor cup. After wrapping, the fireproof cover material can be wrapped around the opening and closing plate and the crescent frame by rotating the control cylinder through the length control motor.

[0024] Step 3: When the fireproof cover material reaches the position of the extrusion column, the extrusion motor rotates the extrusion thread column to control the extrusion column to extrude the fireproof cover material, so that the fireproof cover material fits the anchor cup. Then, the cutting motor is started to rotate the cutting gear to control the blade to cut the fireproof cover material. After the cutting is completed, it is necessary to manually check whether it fits perfectly. If there is any error, it is necessary to manually adjust it.

[0025] Step 4: Next, you can quickly and repeatedly attach the anchor cup until it is attached. After attachment, control the opening and closing motor to rotate the opening and closing gear, so that the crescent frame can be removed from the anchor cup.

[0026] Step 5: When the position of the anchor cup is inconvenient for personnel to work, the snap ring and the fixing hook need to be aligned, and then the fixing block is inserted for fixation. The moving bracket is fixed inside the cargo box of the engineering vehicle. The moving motor rotates the moving gear to control the position of the moving box in the moving bracket. The drive motor rotates the drive gear to adjust the direction of the connecting column and the support plate. The lifting motor rotates the lifting threaded column to raise the lifting cylinder to adjust the construction height. Finally, the control motor rotates the control shaft to control the direction of the fixing hook and the equipment base plate.

[0027] Step Six: Use the four sets of mechanical structures from Step Five to control the direction and height of construction, achieving greater flexibility and enabling faster construction.

[0028] Compared with the prior art, the present invention has at least the following beneficial effects:

[0029] In the above solution, the fire-resistant layer prevents the flames from spreading inward and acts as a framework to maintain the integrity of the fireproof cover, while also providing adhesion for the outer expanded carbonized layer. The foamed fireproof layer can rapidly expand and carbonize upon exposure to fire, providing a dense fire-resistant effect, reducing thermal conductivity and heat convection. The fluorocarbon topcoat provides the fireproof cover with aesthetics and weather resistance, and can also provide warning features as needed.

[0030] The fireproof cover is attached by removing the equipment base plate, the material drawer is pulled out, and the fireproof cover material is placed into the material drawer. The compression spring compresses the positioning plate, the opening and closing motor rotates the opening and closing gear to move the opening and closing plate outward, the length control motor rotates the control cylinder to control the length of the fireproof cover material, the compression motor rotates the compression thread column to control the compression column to compress the fireproof cover material, the cutting motor rotates the cutting gear to control the blade to cut the fireproof cover material, and the retaining ring is fixed by the fixing hook and fixing block. The drive motor rotates the drive gear to make the rotating gear rotate, the lifting motor rotates the lifting thread column to make the lifting cylinder rise, and the control motor rotates the control shaft to make the equipment base plate rotate and move the support. It is then installed on the engineering vehicle, and the position of the moving box is adjusted by the movement motor rotating the movement gear.

[0031] By controlling the motor, crescent frame, and fixing hook, the equipment's performance is greatly enhanced, effectively solving the problem of inconvenient manual construction in special locations. It also speeds up the construction time for anchor cups, greatly relieving work pressure and improving construction safety. Attached Figure Description

[0050] like Figures 1 to 5As shown, an embodiment of the present invention provides a fireproof cover for the anchor cup portion of a cable-stayed bridge and its preparation method, including an equipment base plate 1. A material drawer 2 is inserted into one side of the equipment base plate 1. A compression spring 3 is inserted into the inside of the material drawer 2. A positioning plate 4 is inserted into the inside of the compression spring 3. A rotating shaft 5 is sleeved on the outer surface of the upper side of the positioning plate 4. An epoxy resin 6 is sleeved on the outer surface of the rotating shaft 5. A fire-resistant layer 7 is provided on one side of the epoxy resin 6. A foamed fireproof layer 8 is provided on one side of the fire-resistant layer 7. A fluorocarbon topcoat 9 is provided on one side of the foamed fireproof layer 8. A length control motor 10 is inserted into the upper surface of the material drawer 2. An internal control drum 11 is inserted, and a positioning telescopic plate 12 is sleeved on the outer surface of the control drum 11. A cutting motor 13 is inserted into the upper surface of the equipment base plate 1, and a cutting gear 14 is inserted into the inside of the cutting motor 13. A blade 15 is slidably connected inside the equipment base plate 1. An extrusion motor 16 is snapped into the inner side of the equipment base plate 1, and an extrusion threaded column 17 is inserted into the inside of the extrusion motor 16. An extrusion column 18 is sleeved on the outer surface of the extrusion threaded column 17. An opening and closing gear 19 is inserted into the upper surface of the equipment base plate 1. A small battery 27 is inserted into one side of the equipment base plate 1. A cutting tooth row is opened on one side of the blade 15. The cutting gear 14 and the cutting tooth row are connected to the cutting gear 15. The cutting teeth are mutually compatible. During use, when the environment around the anchor cup is not complex, the equipment base plate 1 can be removed, and the fireproof cover can be attached through semi-automatic operation. The first step is to pull the material drawer 2 out from inside the equipment base plate 1, and then place a new roll of fireproof cover material on the outer surface of the rotating shaft 5. As the fireproof cover material is slowly used, the compression spring 3 will compress the positioning plate 4, keeping the fireproof cover material close to the measuring drum 11. Thus, the length of the fireproof cover to be used during cutting can be continuously controlled by the measuring drum 11. At this time, the anchor cup needs to be inserted into the equipment first, and then the length control motor... 10. Rotate the control drum 11 to control the fireproof cover material to move outward. The fireproof cover material will follow the gap to the inside of the opening plate 21 and the crescent frame 23. When the fireproof cover material reaches the position of the extrusion column 18, the extrusion motor 16 will rotate the extrusion thread column 17 to control the extrusion column 18 to extrude the fireproof cover material, so that the fireproof cover material fits the anchor cup. Then, the length control motor 10 rotates the control drum 11 to control the fireproof cover material to retract until it stops. Then, the cutting motor 13 is started to rotate the cutting gear 14 to control the blade 15 to cut the fireproof cover material. After cutting, it needs to be manually checked to see if it fits perfectly. If there are any defects, they need to be manually dealt with.

[0051] The small battery 27 provides the power required by the internal equipment of the equipment base plate 1. The epoxy resin 6 provides the material with strength and high temperature resistance. The fireproof layer 7 blocks the spread of flames and maintains the fireproof cover and provides adhesion. The foamed fireproof layer 8 expands rapidly and carbonizes to reduce the thermal conductivity and heat convection. The fluorocarbon topcoat 9 provides appearance and weather resistance.

[0052] like Figure 6As shown, in this embodiment, an opening and closing motor 20 is sleeved on the outer surface of the opening and closing gear 19. An opening and closing plate 21 is inserted into the inside of the equipment base plate 1. An angle shaft 22 is inserted into the inside of the opening and closing plate 21. A crescent frame 23 is sleeved on the outer surface of the angle shaft 22. A cover plate 24 is snapped onto the upper surface of the equipment base plate 1. A retaining ring 25 is provided on the upper surface of the cover plate 24. A small driver 26 is inserted into the inside of the cover plate 24. An opening and closing gear row is provided on one side of the opening and closing plate 21. The opening and closing gear 19 meshes with the opening and closing gear row. The upper surface of the equipment base plate 1... The cover plate 24 has a bottom handrail and a top handrail. During use, the opening and closing motor 20 rotates the opening and closing gear 19 to move the opening and closing plate 21 outward. After moving to a certain length, the construction personnel need to manually control the crescent frame 23 and the angle axis 22 to open and close and hug the anchor cup. Then, the opening and closing motor 20 rotates the opening and closing gear 19 to move the opening and closing plate 21 inward, so that the anchor cup is completely inside the crescent frame 23. Then, the fireproof cover can be attached using the above equipment.

[0053] The retaining ring 25 can be installed and removed at will using the fixing hook 28 and fixing block 29. If it is inconvenient for construction personnel to come forward to work on the anchor cup, the subsequent equipment can be started to remotely connect to the anchor cup and attach the fireproof cover. However, the subsequent inspection must be thorough.

[0054] like Figures 7 to 9As shown, in this embodiment, a fixing hook 28 is inserted inside the retaining ring 25, a fixing block 29 is inserted into the upper surface of the fixing hook 28, a support plate 30 is sleeved on the outer surface of the fixing hook 28, a control shaft 31 is inserted into the upper surface of the fixing hook 28, a control motor 32 is sleeved on the outer surface of the control shaft 31, a lifting cylinder 33 is provided on the lower surface of the support plate 30, a connecting post 34 is sleeved on the outer surface of the lifting cylinder 33, a lifting motor 35 is inserted inside the connecting post 34, a lifting threaded post 36 is inserted inside the lifting motor 35, a rotating gear 37 is provided on the lower surface of the connecting post 34, a movable housing 38 is sleeved on the outer surface of the connecting post 34, a drive motor 39 is inserted into the upper surface of the movable housing 38, a drive gear 40 is inserted inside the drive motor 39, a movable motor 41 is snapped into the inside of the movable housing 38, a movable gear 42 is inserted inside the movable motor 41, and a rotating gear... 37 meshes with the drive gear 40. A large battery 43 is inserted into one side of the movable housing 38, and a large driver 44 is snapped into one side of the movable housing 38. A movable bracket 45 is slidably connected to the lower surface of the movable housing 38, and a movable gear rack is provided on the upper surface of the movable bracket 45. The movable gear 42 meshes with the movable gear rack. During use, when the position of the anchor cup is not suitable for construction personnel to move forward, the drive motor 39 can rotate the drive gear 40 to make the rotating gear 37 rotate together, thereby controlling the direction of the connecting column 34 and the support plate 30. The lifting motor 35 rotates the lifting threaded column 36 to make the lifting cylinder 33 rise, and then the height can be adjusted by climbing over the railing. Fireproof covers are attached to the anchor cups in different positions. In addition, the control motor 32 rotates the control shaft 31 to make the fixed hook 28 and the equipment base plate 1 rotate, which can better control the docking direction and the attachment part.

[0055] By installing the mobile bracket 45 onto the engineering vehicle, the position of the mobile box 38 and the distance between it and the anchor cup can be adjusted by rotating the mobile gear 42 through the mobile motor 41 during remote construction, thereby better ensuring the construction speed and installation direction. The large battery 43 provides power to the parts inside the mobile box 38.

[0056] like Figure 3As shown, an embodiment of the present invention provides a fireproof cover for the anchor cup portion of a cable-stayed bridge, comprising a base plate 1 and epoxy resin 6. A fire-resistant layer 7 is provided on one side of the epoxy resin 6, and a foamed fireproof layer 8 is provided on the other side of the fire-resistant layer 7. The foamed fireproof layer 8 and the fire-resistant layer 7 are made of high-silica woven fabric or quartz woven fabric. The foamed fireproof layer 8 is obtained by mixing 3 parts ammonium phosphate, 1 part pentaerythritol, 1 part urea, 2 parts melamine-formaldehyde, 1 part phosphorus pentasulfide, 0.5 parts talc, 10 parts epoxy resin, 3 parts ammonium phosphate, 1 part pentaerythritol, 1 part urea, 2 parts melamine-formaldehyde, and 1 part phosphorus pentasulfide to obtain a mixture. This mixture is then further mixed at high speed with 0.5 parts talc and 10 parts epoxy resin, and extruded using an extrusion device at a temperature of 180-200°C. The mixture is granulated at ℃ to form mixed particles, thereby obtaining a foamed fireproof layer 8. One side of the foamed fireproof layer 8 is coated with a fluorocarbon topcoat 9. The epoxy resin 6 can be designed using a high-temperature resistant silicate + epoxy resin formula, which can provide sufficient strength and high-temperature resistance for the material. The fire-resistant layer 7 is a high-silica woven fabric or quartz woven fabric (fire-resistant layer, preventing the flame from spreading inward and acting as a skeleton to maintain the integrity of the fireproof cover, while also providing adhesion for the outer expanding carbonized layer). The foamed fireproof layer 8 has the characteristics of low additive dosage, high flame retardant efficiency, good material compatibility, low toxicity and environmental protection. It can rapidly expand and carbonize when exposed to fire, providing a dense fire-resistant layer, reducing thermal conductivity and heat convection. The fluorocarbon topcoat 9 provides the fireproof cover with appearance and weather resistance properties, and can also provide warning as needed.

[0057] All electrical components mentioned in this article are connected to an external ULN2003 main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0058] A fireproof cover for the anchor cup portion of a cable-stayed bridge and its preparation method include the following steps when in use;

[0059] Step 1: First, pull out the material drawer 2, then install the fireproof cover material on the rotating shaft 5, and then insert the material drawer 2 into the equipment base plate 1. When it is possible to work manually, the construction personnel can manually pull out the fixing block 29 and remove the equipment base plate 1, and then carry the equipment base plate 1 to work.

[0060] Step 2: The opening and closing plate 21 moves outward by rotating the opening and closing gear 19 through the opening and closing motor 20. When the opening and closing plate 21 reaches its limit length, the crescent frame 23 can be controlled by the angle shaft 22 to wrap around the anchor cup. The opening and closing plate 21 retracts inward by rotating the opening and closing gear 19 through the opening and closing motor 20, so that it completely wraps around the anchor cup. After wrapping, the fireproof cover material can be wrapped around the opening and closing plate 21 and the crescent frame 23 by rotating the measuring cylinder 11 through the length control motor 10.

[0061] Step 3: When the fireproof cover material reaches the position of the extrusion column 18, the extrusion motor 16 rotates the extrusion thread column 17 to control the extrusion column 18 to extrude the fireproof cover material, so that the fireproof cover material fits the anchor cup. Then, the cutting motor 13 is started to rotate the cutting gear 14 to control the blade 15 to cut the fireproof cover material. After the cutting is completed, it is necessary to manually check whether it fits perfectly. If there is any error, it is necessary to manually adjust it.

[0062] Step 4: Next, you can quickly and repeatedly attach the anchor cup until it is attached. After attachment, control the opening and closing motor 20 to rotate the opening and closing gear 19 so that the crescent frame 23 can be disengaged from the anchor cup.

[0063] Step 5: When the position of the anchor cup is inconvenient for personnel to work, the snap ring 25 and the fixing hook 28 need to be aligned, and then the fixing block 29 should be inserted for fixation. The movable bracket 45 is fixed inside the cargo box of the engineering vehicle. The movable box 38 is controlled by the movable motor 41 rotating the movable gear 42. The drive motor 39 rotates the drive gear 40 to adjust the direction of the connecting column 34 and the support plate 30. The lifting motor 35 rotates the lifting threaded column 36 to raise the lifting cylinder 33 to adjust the construction height. Finally, the direction of the fixing hook 28 and the equipment base plate 1 is controlled by the control motor 32 rotating the control shaft 31.

[0064] Step Six: Use the four sets of mechanical structures from Step Five to control the direction and height of construction, achieving greater flexibility and enabling faster construction.

[0065] The technical solution provided by this invention is as follows: The fireproof cover is attached by removing the equipment base plate 1, and the material drawer 2 is pulled out. The fireproof cover material is placed inside the material drawer 2. As the fireproof cover material is gradually used, the compression spring 3 compresses the positioning plate 4, keeping the fireproof cover material close to the control drum 11. This allows for continuous control of the length of the fireproof cover used during cutting via the control drum 11. First, the anchor cup is inserted into the equipment. Then, the length control motor 10 rotates the control drum 11 to control the fireproof cover material to move outwards. The fireproof cover material will follow the gap to the inside of the opening plate 21 and the crescent frame 23. When the fireproof cover material reaches the position of the extrusion column 18, the extrusion motor 16 rotates the extrusion threaded column 17 to control the extrusion. The column 18 compresses the fireproof cover material, making it fit the anchor cup. Then, the length control motor 10 rotates the measuring drum 11 to control the retraction of the fireproof cover material until it stops. Then, the cutting motor 13 is started to rotate the cutting gear 14 to control the blade 15 to cut the fireproof cover material. After cutting, it needs to be manually checked to ensure it fits perfectly. If there are any defects, they can be manually corrected. The small battery 27 provides the power required by the internal equipment of the equipment base plate 1. The opening and closing motor 20 rotates the opening and closing gear 19 to move the opening and closing plate 21 outward. After moving to a certain length, the construction personnel need to manually control the crescent frame 23 and the angle axis 22 to open and close and hug the anchor cup. Then, the opening and closing motor 20 rotates the opening and closing gear 19 to open and close. Plate 21 moves inward, so that the anchor cup is completely inside the crescent frame 23. Next, the fireproof cover can be attached using the aforementioned equipment. The retaining ring 25 can be easily installed and removed using the fixing hook 28 and fixing block 29. If the anchor cup is inconvenient for construction personnel to access, subsequent equipment can be activated to remotely connect the anchor cup and attach the fireproof cover. However, thorough inspection is essential. When the anchor cup's position is unsuitable for personnel to access, the drive motor 39 can rotate the drive gear 40, causing the rotating gear 37 to rotate as well, thereby controlling the direction of the connecting column 34 and the support plate 30. The lifting motor 35 rotates the lifting threaded column 36, causing the lifting cylinder 33 to rise, allowing the height to be adjusted by climbing over the railing. The anchor cups are fitted with fireproof covers, and the control motor 32 rotates the control shaft 31 to rotate the fixed hook 28 and the equipment base plate 1. This allows for better control of the docking direction and the fitting area. By installing the mobile bracket 45 onto the engineering vehicle, the position of the mobile box 38 and the distance between it and the anchor cup can be adjusted by rotating the mobile gear 42 through the mobile motor 41 during remote construction. This ensures better construction speed and installation direction. The large battery 43 provides power to the internal parts of the mobile box 38, greatly enhancing the equipment's performance. This effectively solves the problem of inconvenient manual construction in special locations, speeds up the usual anchor cup construction time, greatly alleviates work pressure, and improves construction safety.
