Description

Technical Field

[0001] This invention belongs to the field of airport pavement repair technology, and in particular relates to an umbrella-shaped support platform and method with a metal frame as the main body. Background Technology

[0002] With the rapid development of my country's economy, the demand for air transport has increased, the total number of aircraft takeoffs and landings has increased, and the number of newly built civil airports has continued to rise. Civil airports have become an important engine for regional economic development. However, in the event of sudden pavement damage, rapid emergency repairs of airport runways are required. In recent years, pavement repair technologies have employed precast reinforced concrete slabs, aluminum alloy pavement panels, roller-compacted concrete, and grouting with crushed sand and gravel. For example, invention patent application number CN202210094338.2 discloses a method for setting up a prefabricated airport pavement system to maintain locally damaged areas of the airport pavement. It uses prefabricated airport slabs for installation, but the installation process involves adjusting the base height using cast-in-place concrete, which not only consumes a lot of materials but also has poor timeliness, making it difficult to achieve the goal of rapid pavement repair.

[0003] Currently, the repair technology for damaged pavements at civil airports in my country primarily relies on cast-in-place high-performance concrete. This method suffers from drawbacks such as poor construction timeliness, the need to wait for the concrete to reach the required strength, low efficiency, high raw material requirements, and high costs. Therefore, a construction device and repair technology capable of rapid pavement repair and improved efficiency is needed to overcome the shortcomings of traditional methods. Thus, addressing the challenges of rapid pavement repair in existing methods, it is necessary to propose an umbrella-shaped support platform with a metal frame as a rapid pavement repair device to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose an umbrella-shaped support platform device and method with a metal frame as the main body to realize the rapid repair of damaged airport pavement and improve efficiency.

[0005] To achieve the purpose of this invention, this invention discloses an umbrella-shaped support platform with a metal frame as the main body, including an umbrella-shaped support platform and a base; the umbrella-shaped support platform is a support structure of the metal frame main body; the base is placed at the bottom of the pit to support the upper umbrella-shaped support platform; both the umbrella-shaped support platform and the base are sleeved on the main column.

[0006] Furthermore, the base includes a steel plate, a steel cylindrical sleeve, and ribs. The steel plate is located at the bottom of the pit, and the steel cylindrical sleeve is located on the upper surface of the steel plate. Ribs are connected between the side wall of the steel cylindrical sleeve and the steel plate. The lower end of the main column is located inside the steel cylindrical sleeve, and the umbrella-shaped support platform is sleeved on the main column.

[0007] Furthermore, a bolt hole is provided at the cross-section of the main column, and a round steel tube with a through hole is sleeved at the cross-section of the main column. The anti-rotation bolt passes through the through hole and is locked in the bolt hole at the cross-section of the main column to prevent rotation caused by loosening of the lap joint at the cross-section of the main column; the round steel tube is used to improve the rigidity at the cross-section.

[0008] Furthermore, the main column includes a base main column and an umbrella main column; the bottom of the base main column is connected to the base, and the upper end of the base main column is fixed to the lower end of the umbrella main column through a connecting mechanism. A connecting mechanism is also provided at the upper end of the umbrella main column; the lower connecting mechanism is used to fix the upper end of the base main column and the lower end of the umbrella main column, as well as the metal frame connecting the umbrella-shaped support platform; the upper connecting mechanism is used to connect the metal frame of the umbrella-shaped support platform.

[0009] Furthermore, the metal frame includes several inclined support rods and horizontal support rods; the lower ends of several inclined support rods are connected to the lower connecting mechanism, and the ends of several horizontal support rods are connected to the upper connecting mechanism; each inclined support rod has a sliding device connected to its upper end, the sliding device is sleeved on the horizontal support rod, and the inclined support rod is slidably connected to the corresponding horizontal support rod body through the sliding device.

[0010] Furthermore, the connecting mechanism includes a sleeve, a disc support plate, ribs, and flange bolts. A disc support plate is provided on the outside of the sleeve, and the lower surface of the disc support plate is connected to the outer side of the sleeve through ribs. A flange bolt is provided on the outer side of the sleeve above the disc support plate, and several connecting plates are welded to the outside of the flange bolts. The lower end of the inclined support rod is connected to the connecting plate of the lower connecting mechanism, and the end of the horizontal support rod is connected to the connecting plate of the upper connecting mechanism. When the umbrella-shaped support platform is unfolded, the flange bolts of the lower connecting mechanism move upward, causing the inclined support rod to push the sliding device to slide outward. Each horizontal support rod unfolds and forms a plane at the top, connecting the outer ends of adjacent horizontal support rods through horizontal connecting rods to achieve the overlapping of one layer of support platform. When the umbrella-shaped support platform is retracted, the flange bolts of the lower connecting mechanism move downward, causing the inclined support rod to pull the sliding device to slide inward, and each horizontal support rod retracts.

[0011] Furthermore, the upper end of the exposed main column of the lower umbrella-shaped support platform and the lower end of the main column of the upper umbrella-shaped support platform are connected by a connecting mechanism to achieve the overlapping of multiple umbrella-shaped support platforms; the ends of the horizontal support rods of the lower umbrella-shaped support platform and the upper umbrella-shaped support platform are connected by vertical connecting rods.

[0012] Furthermore, pins are welded to the bottom of the horizontal support rods. When the umbrella-shaped support platform is unfolded, the pins limit the sliding device, so that the top of each horizontal support rod is flat.

[0013] To achieve the objectives of this invention, a support method is also disclosed, comprising the following steps:

[0014] Step 1: First, assemble the base and the main column, fit the round steel pipe at the variable cross section, align the holes on the main column and the round steel pipe, and tighten the anti-rotation bolts.

[0015] Step 2: As a whole, fit the welded disc support plate, rib plate, flange bolts, and connecting plate onto the main column. The first-layer support platform includes the upper connecting mechanism and the lower connecting mechanism.

[0016] Step 3: Cut the flanges at both ends of the inclined support rod to avoid obstruction of end rotation due to manufacturing defects; at the same time, weld thin steel plates to the web plates at both ends of the inclined support rod to improve the rigidity of the end. Then, connect one end of the inclined support rod to the connecting plate on the flange bolt of the lower connecting mechanism with bolts.

[0017] Step 4: Cut a notch in one end of the horizontal support rod to prevent the end from being obstructed from rotating due to manufacturing defects. At the same time, weld a thin steel plate to the web of the inner end of the horizontal support rod to improve the rigidity of the end. Then connect the end to the connecting plate on the flange bolt of the upper connecting mechanism with bolts, and place the sliding device on it.

[0018] Step 5: Connect the unconnected end of the inclined support rod to the sliding device on the horizontal support rod, and then connect the horizontal connecting rods between the horizontal support rods. This completes the connection of one layer of support platform.

[0019] Step 6: Depending on the actual size and depth of the pit, N layers of support platforms can be added upwards. The construction steps are repeated from Step 2 to Step 5 above. The two ends of the vertical connecting rod are connected to the outer ends of the horizontal support rods on the same vertical plane of the upper and lower layers to play a role in force transmission, making the overall structure more stable and stronger in load-bearing capacity.

[0020] Step 7: After assembling the umbrella-shaped support platform, place it into the pit in the pavement. The main filling material for the pit is the umbrella-shaped support platform. Fill the remaining gaps with sand and gravel to level it. Finally, place a thin cement board on top and pour quick-drying concrete to keep it level with the undamaged pavement.

[0021] Step 8: Once the quick-drying concrete has solidified and reached the expected strength, the rapid repair of the pothole pavement is completed.

[0022] Compared with the prior art, the significant progress of the present invention is that it has the advantages of small carrier, fast construction, low difficulty, overlapping, and single-person operation. It can quickly repair potholes without specific shapes, reduce the difficulty of operation and reduce the demand for materials, and can realize the task of rapid repair of important infrastructure such as pavement in emergency situations.

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1As shown, an umbrella-shaped support platform with a metal frame as its main body includes an umbrella-shaped support platform and a base 1. The umbrella-shaped support platform is a support structure for the metal frame. The base 1 is placed at the bottom of the pit to support the upper umbrella-shaped support platform. Both the umbrella-shaped support platform and the base are sleeved on the main column 2. The main column 2 includes a base main column and an umbrella body main column. The bottom of the base main column is connected to the base 1, and the upper end of the base main column is fixed to the lower end of the umbrella body main column by a connecting mechanism 14. A connecting mechanism 14 is also provided at the upper end of the umbrella body main column. The lower connecting mechanism 14 is used to fix the upper end of the base main column and the lower end of the umbrella body main column, as well as to connect the metal frame of the umbrella-shaped support platform. The upper connecting mechanism 14 is used to connect the metal frame of the umbrella-shaped support platform.

[0039] Specifically, after the connecting mechanism 14 is fitted into both the upper end of the base main column and the lower end of the umbrella body main column, the connection is welded to increase the connection strength.

[0040] Specifically, the umbrella-shaped support platform uses steel components as its main body, providing high strength and rigidity. It can support the thin cement slab above, on which quick-drying concrete can be poured for rapid repair of potholes during wartime. The components are connected by connecting plates and bolts, allowing for installation by a single person. Construction is fast and easy, making it readily applicable for pothole repair. The umbrella-shaped support platform can be layered, with the number of layers adjusted according to the actual size and depth of the pothole. A thin cement slab is placed on top, and quick-drying concrete is poured, ensuring it remains level with the undamaged road surface.

[0041] like Figure 1 , Figure 4 As shown, the base 1 includes a steel plate, a steel cylindrical sleeve, and ribs. The steel plate is located at the bottom of the pit, and the steel cylindrical sleeve is located on the upper surface of the steel plate. Ribs connect the side wall of the steel cylindrical sleeve to the steel plate. The lower end of the main column 2 is located inside the steel cylindrical sleeve, and an umbrella-shaped support platform is fitted onto the main column 2. A bolt hole is provided at the variable cross-section of the main column 2, and a round steel pipe with a through hole is fitted over the variable cross-section of the main column. An anti-rotation bolt 3 passes through the through hole and is locked in the bolt hole at the variable cross-section of the main column to prevent rotation caused by loosening of the joint at the variable cross-section of the main column. The round steel pipe is used to improve the rigidity at the variable cross-section. The base can stably support the upper structure and is not easy to collapse.

[0042] like Figure 1 , Figure 5 As shown, the metal frame includes several inclined support rods 9 and horizontal support rods 8; the lower ends of the several inclined support rods 9 are connected to the lower connecting mechanism 14, and the ends of the several horizontal support rods 8 are connected to the upper connecting mechanism 14; each inclined support rod 9 has a sliding device 10 connected to its upper end, the sliding device 10 is sleeved on the horizontal support rod 8, and the inclined support rod 9 is slidably connected to the corresponding horizontal support rod 8 through the sliding device 10.

[0043] Specifically, the inclined support rod 9 serves to support the upper horizontal support rod 8 and transmit the force on the horizontal support rod 8 to the main column 2.

[0044] like Figures 4-8 As shown, the connecting mechanism 14 includes a sleeve, a rib plate 4, a disc support plate 5, and flange bolts 6. A disc support plate 5 is provided on the outside of the sleeve. The lower surface of the disc support plate 5 is connected to the outer side of the sleeve through the rib plate 4. A flange bolt 6 is provided on the outer side of the sleeve above the disc support plate 5. Several connecting plates 7 are welded to the outside of the flange bolt 6. The lower end of the inclined support rod 9 is connected to the connecting plate 7 of the lower connecting mechanism 14, and the end of the horizontal support rod 8 is connected to the connecting plate 7 of the upper connecting mechanism 14. When the umbrella-shaped support platform is unfolded, the flange bolts 6 of the lower connecting mechanism 14 move upward, causing the inclined support rod 9 to push the sliding device 10 to slide outward. Each horizontal support rod 8 unfolds and forms a plane at the top. The outer ends of adjacent horizontal support rods 8 are connected through horizontal connecting rods 12 to achieve the overlapping of one layer of support platform. When the umbrella-shaped support platform is retracted, the flange bolts 6 of the lower connecting mechanism 14 move downward, causing the inclined support rod 9 to pull the sliding device 10 to slide inward, and each horizontal support rod 8 retracts. A pin 11 is welded below the horizontal support rod 8. When the umbrella-shaped support platform is unfolded, the pin 11 limits the sliding device 10, so that the top of each horizontal support rod 8 is flat.

[0045] Specifically, rib 4 is welded below the disc support plate 5 and simultaneously welded to the surface of the outer round steel pipe to assist the disc support plate 5 in supporting the upper components. Flange bolts 6 are connected to the top of the disc support plate, and connecting plates 7 are welded to each side of the flange bolts 6 for connecting components. The flange bolts 6 also improve the stiffness of the variable cross-section. Connecting plates 7 are welded to the sides of the flange bolts 6 and the upper and lower surfaces of the horizontal support rods 8. A hole is drilled in the center of the connecting plate 7, and the center holes of the end webs of the diagonal support rods 9 and the vertical connecting rods 13 are aligned with the hole in the connecting plate 7. Bolts are then tightened to connect the two together.

[0046] like Figure 2 , Figure 3 As shown, the upper end of the exposed main column 2 of the lower umbrella-shaped support platform and the lower end of the main column 2 of the upper umbrella-shaped support platform are connected by the connecting mechanism 14 to realize the overlapping of multiple umbrella-shaped support platforms; the ends of the horizontal support rods 8 of the lower umbrella-shaped support platform and the upper umbrella-shaped support platform are connected by the vertical connecting rods 13.

[0047] Specifically, the main column 2 is made of round steel pipe, running from bottom to top and connecting all parts. The diagonal support rod 9 is made of I-beams, with notched flanges at both ends to prevent end rotation from being obstructed due to manufacturing defects. Thin steel plates are welded to the webs at both ends of the I-beam to increase its end rigidity. The horizontal support rods 8 are also made of I-beams; when extended, the upper surfaces of all horizontal support rods must be on the same horizontal plane to collectively support the upper concrete slab. The horizontal connecting rod 12, also made of I-beams, connects the horizontal support rods on the same support platform, ensuring more even force distribution and improving stability. The vertical connecting rod 13, made of square steel pipe, connects the horizontal support rods on the upper and lower layers, transmitting force and making the overall structure more stable.

[0048] Example

[0049] like Figures 9-11 As shown, a method for using an umbrella-shaped support platform with a metal frame as its main body includes the following steps:

[0050] Step 1: First, connect the base 1 and the main column 2 together, put the round steel pipe on the variable cross section, align the holes on the main column and the round steel pipe, and tighten the anti-rotation bolt 3.

[0051] Step 2: Fit the welded rib plate 4, disc support plate 5, flange bolts 6, and connecting plate 7 onto the main column 2. The first-layer support platform includes the upper connecting mechanism 14 and the lower connecting mechanism 14.

[0052] Step 3: Cut the flanges at both ends of the inclined support rod 9 to avoid the end rotation being obstructed due to manufacturing defects; at the same time, weld thin steel plates to the web plates at both ends of the inclined support rod 9 to improve the rigidity of the end. Then, connect one end of the inclined support rod 9 to the connecting plate 7 on the flange bolt 6 of the lower connecting mechanism 14 by bolts.

[0053] Step 4: Cut a notch in one end of the flange of the horizontal support rod 8 to prevent the end from being obstructed due to manufacturing defects. At the same time, weld a thin steel plate to the web of the inner end of the horizontal support rod 8 to improve the rigidity of the end. Then, connect the end to the connecting plate 7 on the flange bolt 6 of the upper connecting mechanism 14 with bolts, and place the sliding device 10 on it.

[0054] Step 5: Connect the unconnected end of the inclined support rod 9 to the sliding device 10 on the horizontal support rod 8, and then overlap the horizontal connecting rod 12 between the horizontal support rods 8. This completes the overlap of one layer of support platform.

[0055] Step 6: Build a double-layer support platform according to the actual size and depth of the pit. The two ends of the vertical connecting rod 13 are connected to the outer ends of the horizontal support rods 8 on the same vertical plane of the upper and lower layers to play a role in force transmission, making the overall structure more stable and stronger in load-bearing capacity.

[0056] Step 7: Repeat steps 1 to 6 six times in total. After assembling the six double-layer umbrella-shaped support platforms, place the six umbrella-shaped support platforms into the pits in the pavement. The pit space is mainly filled with umbrella-shaped support platforms placed in a 2*3 pattern. The remaining gaps are filled with sand and gravel to level the surface. Finally, place a thin cement board on top and pour quick-drying concrete to keep it level with the undamaged pavement.

[0057] Step 8: Once the quick-drying concrete has solidified and reached the expected strength, the rapid repair of the pothole pavement is completed.
