Description

Technical Field

[0001] The present application relates to the technical field of underground rails, and in particular to a construction and monitoring method for repairing hangar door ground rails. Background Art

[0002] A maintenance hangar is a large, single-story building used for aircraft maintenance. It serves as the primary structure in an aircraft maintenance area. Unlike ordinary industrial doors, the doors of a maintenance hangar are typically larger. During the hangar door installation process, specialized underground tracks are pre-laid.

[0003] Typical single-leaf hangar doors weigh between 50 and 90 tons, requiring a high load-bearing capacity and high straightness for the floor rails. The typical hangar door floor rail installation method involves casting a floor rail groove in the ground, which is then secured within the groove using bolts, channel steel, and other components. Therefore, the straightness of the floor rail groove directly impacts the straightness of the rails. However, the casting of the floor rail groove relies heavily on the staff's experience, and the shape is finalized after a single casting. If the floor rail groove is uneven or has inconsistent depth, the straightness of subsequent floor rails will also be affected. Summary of the Invention

[0004] In order to improve the straightness of the hangar maintenance door ground rail, the present application provides a construction and monitoring method for the hangar maintenance door ground rail.

[0005] This application provides a method for constructing and monitoring a hangar door rail for maintenance using the following technical solutions:

[0006] A method for constructing and monitoring a hangar door rail for maintenance includes the following steps:

[0007] S1: Before pouring the gate concrete structure layer, make a computer layout model according to the ground rail and elevation position in the drawing, arrange the layout points at the construction site and check the plane and elevation position of the layout points;

[0008] S2: implant screw;

[0009] S3: Screw the first set of bolts into the screw rod. The screwing depth of the first set of bolts is calculated according to the height between the sleeper and the ground rail. The first set of bolts is used to support the sleeper and fix it at the predetermined elevation.

[0010] S4: Install sleepers;

[0011] S5: Screw the second set of bolts into the screw rod. The second set of bolts cooperates with the first set of bolts to completely fix the sleeper at the established elevation.

[0012] S6: Install the floor rails on the sleepers and adjust the straightness. Once the straightness requirement is met, tighten the floor rails.

[0013] S7: Start pouring the gate concrete structure layer. When pouring the gate concrete structure layer, the layout point is monitored in real time. When deviation occurs, the layout point automatically issues a warning instruction and feeds back to the control computer for real-time adjustment to eventually form the ground rail groove.

[0014] By adopting the above technical solution, the screw rod can be initially positioned to determine the initial position of the sleeper. The screw rod and the first set of bolts can further determine the position of the sleeper, and the second set of bolts and the first set of bolts can completely fix the position of the sleeper. Through the above multiple positioning and fixing, the straightness of the sleeper is guaranteed, providing a precise foundation for the subsequent pouring of the ground rail groove. When pouring the gate concrete structure layer, the implementation and monitoring of the layout points will also effectively improve the straightness of the ground rail groove. Through multiple positioning and multiple inspections, the straightness of the ground rail groove can be effectively improved, that is, the straightness of the ground rail can be effectively guaranteed.

[0015] Optionally, in steps S2-S7, a secondary pouring method is used for pouring;

[0016] After the first pouring is completed, the screw rods are implanted into the inner layer of concrete using the chemical anchoring method, and then the second pouring is carried out.

[0017] By adopting this technical solution, the concrete structure formed after a single pour provides a foundation for the subsequent screw placement. On the one hand, the segmented pouring method provides a better pouring effect, effectively improving the service strength of the gate's concrete structure. On the other hand, the segmented pouring method makes it easier to adjust the position of the ground rails installed on the sleepers in real time, effectively improving the straightness of the ground rails.

[0018] Optionally, in step S6, a pressing plate for fixing the ground rail is provided on the sleeper, one end of the pressing plate is fixed to the sleeper with bolts, and the other end is pressed onto the ground rail.

[0019] By adopting the above technical solution, compared with the traditional bolt fixing method, the pressure plate fixing method is more stable, and the fixing area between the pressure plate and the ground rail is larger, which can effectively improve the stability of the ground rail. On the other hand, the pressure plate fixing method of the ground rail is convenient for real-time adjustment of the straightness of the ground rail.

[0020] Optionally, the cross-section of the floor rail is I-shaped, comprising a track portion cooperating with the gate and a fixing portion fixed to the sleepers, with pressure plates being provided on both sides of the fixing portion;

[0021] A pressing groove adapted to the fixing part is provided on one end of the pressing plate used for pressing the fixing part.

[0022] By adopting the above technical solution, the cooperation between the pressing groove and the fixing part can effectively improve the fixing effect of the pressing plate on the fixing part of the ground rail; the pressing groove can also limit the pressing plate, and the ground rail fixed by the pressing plate is not easy to move, which can effectively improve the straightness of the ground rail.

[0023] Optionally, a fixing hole is opened on the floor rail along the length direction of the floor rail, and a bolt passes through the fixing hole to fix the pressure plate, and the length of the fixing hole is greater than the width of the fixing part.

[0024] By adopting the above technical solution, when adjusting the straightness of the floor rail, it is necessary to adjust the fixing position of the floor rail and the sleeper, so the position of the bolts fixing the floor rail and the sleeper will also change. The fixing hole facilitates the position change of the bolt, which is more convenient for the staff to operate.

[0025] Optionally, a mounting hole adapted to the fixing hole is opened on the fixing portion of the floor rail along the width direction of the floor rail.

[0026] By adopting the above technical solution, the mounting holes can cooperate with the fixing holes, thereby expanding the adjustment range of the floor rail and the sleeper, making the adjustment of the straightness of the floor rail smoother.

[0027] Optionally, angle steels are provided at the corners of the cast floor rail groove to protect the concrete at the corners of the floor rail groove.

[0028] By adopting the above technical solution, since the corners of the ground rail groove are subjected to greater force, the concrete at the corners is prone to cracks or even falling after long-term use. The angle steel can protect the concrete at the corners and enhance its strength.

[0029] Optionally, during the secondary pouring process, support bars are implanted in the concrete structure layer of the gate, the support bars are arranged at an angle, and one end of the support bars abuts against and is fixed to the angle steel.

[0030] By adopting the above technical solution, the supporting ribs can further effectively strengthen the supporting strength of the angle steel and enhance the load-bearing capacity of the corners of the ground rail groove.

[0031] Optionally, the end of the support rib away from the angle steel is V-shaped, and the V-shaped opening side of the support rib faces away from the angle steel.

[0032] By adopting the above technical solution, the connection between the supporting reinforcement and the concrete is strengthened, the supporting strength of the angle steel is further effectively strengthened, and the load-bearing capacity of the corners of the ground rail groove is enhanced.

[0033] Optionally, the stakeout points in step S1 are set at intervals of 4 meters.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. This application uses the positioning of the screw and two sets of nuts and the monitoring of multiple setout points to conduct multi-dimensional positioning and inspection of the pouring process of the rail groove and the installation of the rail from the initial construction stage, during the construction process, and until the completion of the construction. This can effectively improve the straightness of the rail groove and the straightness of the rail.

[0036] 2. The use of secondary pouring can increase the adjustment opportunities during the installation of the floor rail, so as to adjust the position of the floor rail in real time and improve the straightness of the floor rail;

[0037] 3. By setting the pressure plate, compared with the traditional bolt fixation, the pressure plate fixation method is more stable, which can effectively increase the stability of the ground rail and is also more convenient for adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In the description of this application, it should be noted that the terms "horizontal", "vertical", "close", "far", "up", "down", "inside", etc. are based on the relative relationships shown in the drawings, and are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the process or module referred to must have a specific orientation, state and operation, and therefore cannot be understood as limiting the present invention. Figure 1-2 , further details of this application are given.

[0042] The embodiments of the present application disclose a method for constructing and monitoring a hangar door rail for maintenance.

[0043] Reference Figure 1 and Figure 2 A construction and monitoring method for repairing hangar door rails includes:

[0044] S1: 1) Preparation before construction, conduct site surveys, and carefully prepare the construction organization design; 2) Carry out necessary clearance of obstacles underground and above ground at the construction site, level the site, and reasonably arrange on-site facilities to ensure normal construction; 3) Preparation of raw materials; 4) Mechanical equipment and auxiliary equipment: Inspection and maintenance before entering the site to ensure the intact rate upon entering the site; 5) Provide necessary training to construction personnel, do a good job of briefing, and assign people to specific positions and responsibilities.

[0045] S2: Before pouring the gate concrete structure layer, a computer layout model is made according to the ground rail 5 and elevation position in the drawing. The layout model is then arranged at the construction site, with a layout point every 4 meters. The plane and elevation position of the first layout point are checked;

[0046] S3: The first concrete structure is poured. After the pouring is completed, the screw 1 is implanted in the first poured concrete by chemical rebar planting. During the pouring of the first concrete structure, the layout point is monitored in real time. When deviation occurs, the layout point automatically issues a warning instruction and feeds back to the control computer for real-time adjustment. All adjustments must be completed before the initial setting of the concrete.

[0047] S4: Calculate the height of the first set of bolts 2 based on the height of the sleeper 4 and the ground rail 5. The first set of bolts 2 is used to support the sleeper 4. Screw the first set of bolts 2 into the screw rod 1.

[0048] S5: The sleeper 4 passes through the screw 1 and is fixed on the screw 1 and the first set of bolts 2. During the installation process, the straightness of the sleeper 4 is detected in real time, and the first set of bolts 2 at the corresponding position are tightened for adjustment;

[0049] S6: Screw the second set of bolts 3 into the screw rod 1. The second set of bolts 3 cooperates with the first bolts to fix the sleeper 4 at a predetermined elevation. During the process of tightening the second set of bolts 3, the straightness of the sleeper 4 is detected in real time, and the second set of bolts 3 at the corresponding position are tightened for adjustment.

[0050] S7: Installing the ground rail 5 on the sleeper 4;

[0051] A plurality of ground rails 5 are placed on the sleeper 4 at equal intervals along the length direction of the sleeper 4, and a plurality of fixing holes are opened on the sleeper 4 at intervals along the length direction of the sleeper 4. The length of each fixing hole is greater than the width of a single ground rail 5, so as to facilitate adjustment of the connection position between the ground rail 5 and the sleeper 4;

[0052] The cross section of the ground rail 5 is I-shaped, including a track portion 51 and a fixing portion 52. The track portion 51 is largely matched with the maintenance hangar, and the fixing portion 52 is fixed to the sleeper 4. A mounting hole that matches the fixing hole is opened on the fixing portion 52 along the width direction of the fixing portion 52.

[0053] In the process of adjusting the straightness of the floor rail 5 , the position of the floor rail 5 needs to be adjusted in real time. The strip-shaped mounting holes and the strip-shaped fixing holes can expand the adjustment range of the floor rail 5 and make operation more convenient.

[0054] The ground rail 5 is connected to the sleeper 4 via a pressing plate 6 . One end of the pressing plate 6 is fixed to the sleeper 4 via bolts. A pressing groove 61 is provided at the other end of the pressing plate 6 , and the pressing groove 61 is adapted to the fixing portion 52 .

[0055] Compared with the traditional bolt fixing method, the contact area between the pressing plate 6 and the ground rail 5 is larger, and the pressing plate 6 can fix the ground rail 5 more firmly. On the other hand, the cooperation between the pressing groove 61 and the pressing plate 6 enables the pressing groove 61 to limit the pressing plate 6 in a certain position, thereby preventing the ground rail 5 from being separated from the pressing plate 6, or the ground rail 5 from being skewed and separated from the pressing groove 61.

[0056] On the bolts fixing the pressing plate 6 and the sleeper 4 , fixing nuts are provided at the lower part of the sleeper 4 and the upper part of the pressing plate 6 . The double fixing nuts can further improve the stability of the ground rail 5 .

[0057] S8: Perform the second concrete structure pouring, implant the support bars 71 in the concrete structure layer, and set the angle steels 7 at the corners of the ground rail groove 8 when pouring the corners of the ground rail groove 8;

[0058] One end of the support rib 71 is in contact with and fixed to the angle steel 7, and the other end is suspended. The suspended end of the support rib 71 is inclined 45 degrees from top to bottom in a direction away from the angle steel 7. The end of the support rib 71 away from the angle steel 7 is V-shaped, and the tightly supported V-shaped opening is away from the angle steel 7.

[0059] The supporting ribs 71 can support the angle steel 7 and enhance the supporting capacity and strength of the angle steel 7. During the push and pull process of the hangar door, the corners of the ground rail groove 8 are subjected to greater forces. After a period of use, the concrete at the corners of the ground rail groove 8 is prone to cracks and even concrete falling, which will affect the normal use of the door. The falling concrete will also affect the normal opening and closing of the door.

[0060] The angle steel 7 can effectively enhance the load-bearing capacity of the corners of the ground rail groove 8 and reduce the possibility of cracks appearing at the corners of the ground rail groove 8 and the falling off of concrete.

[0061] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
