Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and in particular to a method for assembling and constructing hangar doors. Background Technology

[0002] In recent years, the construction of aircraft hangars and large factories in my country has developed rapidly. A large number of steel structure hangars and factories with regional characteristics, innovative concepts and new technologies have emerged. Hangar doors, with their advantages of large span and high security, are widely used in large aircraft hangars.

[0003] Due to the large span and weight of hangar doors, their overall transportation and installation pose significant safety hazards and quality issues. Typically, a modular, high-altitude assembly method is used, which involves substantial work in high-altitude assembly and welding. Furthermore, it requires the erection of high-altitude assembly scaffolding, which is difficult and carries significant safety and quality risks, hindering on-site installation safety, quality, and schedule control. Therefore, a hangar door assembly method is needed to address the problems of excessive workload and high safety risks associated with the modular, high-altitude assembly of hangar doors in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a method for assembling and constructing hangar doors, which can solve the problems of large workload and high safety risks in the separate high-altitude assembly of hangar doors in the prior art.

[0005] This invention is implemented as follows:

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

[0012] Step 6: Run and test the hangar gate.

[0013] The on-site construction work area includes a construction passage, a temporary track storage area, a door assembly area, and a temporary door component storage area. The door assembly area is located outside the door opening of the hangar gate, and the temporary door component storage area is located next to the door assembly area, forming an assembly site. The temporary track storage area is located along one side of the assembly site, and the construction passage is located along the side of the temporary track storage area away from the assembly site.

[0014] The length of the door assembly area is 1 times the height of the hangar door, and the width of the door assembly area is the same as the width of the hangar. The door assembly area is a hardened assembly site.

[0015] A 380V construction power supply with a power consumption of not less than 20kW should be provided within a 30m radius of the center of the hangar door opening.

[0016] The upper track system includes an upper track bracket and a gate upper track. The installation method of the upper track system is as follows: the gate upper track is laid flat on the ground beam, the upper track bracket is installed on the gate upper track to form the upper track system; then the upper track system is vertically lifted to the lower chord steel beam of the gate head beam, and the upper track bracket is placed on the lower chord steel beam of the gate head beam.

[0017] The lower track system includes track fixing components, a lower gate track, a slope protection, and a drainage outlet frame. The installation method of the lower track system is as follows: the track fixing components are laid on the cast-in-place ground beam, the horizontal position of the track fixing components is adjusted and then fixed on the ground beam, and the lower gate track is fixed on the track fixing components; the slope protection is set between the two sides of the track fixing components and the ground, and finally the drainage outlet frame is installed and connected to the drainage system.

[0018] Step 3 includes the following sub-steps:

[0019] Step 3.1: Install the left mullion, right mullion, and middle mullion in the door assembly area. The length of the left mullion, right mullion, and middle mullion is set along the length of the door assembly area on the construction site. The left mullion, middle mullion, and right mullion are arranged from left to right along the width of the door assembly area.

[0020] Step 3.2: Install the upper side stiles at the top of the left, right, and middle stiles, and install the lower side stiles at the bottom of the left, right, and middle stiles;

[0021] Step 3.3: Install the upper mullion component on top of the upper mullion, and install the lower mullion component on top of the lower mullion;

[0023] Step 3.5: Install several horizontal wind-resistant beams at intervals between the upper and lower mullions, with the horizontal wind-resistant beams perpendicularly connected to the left, right, and middle mullions;

[0024] Step 3.6: Install several secondary wind-resistant columns vertically between the upper and lower mullions, and connect the secondary wind-resistant columns vertically to the horizontal wind-resistant beams; install skirt brackets between the lower mullion and the left and right mullions;

[0025] Step 3.7: The diagonal supports are arranged in an X-shaped structure along the diagonal of the gate frame;

[0026] Step 3.8: Install several panel beams at intervals on the front of the gate frame;

[0027] Step 3.9: Install the sealing plate frame on top of the upper mullion;

[0028] Step 3.10: Install the sealing plate on the top of the gate frame using the sealing plate frame.

[0029] Step 4 includes the following sub-steps:

[0030] Step 4.1: The upper guide wheel of the hangar door is pre-installed onto the upper track of the upper track system;

[0031] Step 4.2: Hoist the main gate frame to the door lifting area at the hangar main gate opening;

[0032] Step 4.3: Slowly insert the upper part of the gate frame into the guide space of the gate track;

[0033] Step 4.4: Place the bottom of the gate frame onto the corresponding lower track of the gate lower track system;

[0034] Step 4.5: Install the upper guide wheel onto the upper stile component of the gate frame, and install the lower guide wheel onto the lower stile component of the gate frame.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1. This invention first installs the upper and lower track systems of the gate, then assembles the gate frame on the construction site, and uses a truck crane to hoist the entire gate frame into place for installation and fixation. This greatly reduces the workload of high-altitude assembly and welding, and eliminates the need to erect high-altitude assembly frames. This solves the problems of high difficulty, safety risks, and quality risks associated with the erection of frames, and is beneficial to the safety, quality, and schedule control of the hangar gate installation on site.

[0037] 2. This invention provides an on-site construction work area, including a construction passage for transport vehicles, a temporary track storage area for stacking upper and lower track system components, a door leaf assembly area for assembling the gate frame, and a temporary door leaf component storage area. The width of the door leaf assembly area is the same as the width of the hangar door, and the length of the door leaf assembly area is 1 times the height of the hangar door. This ensures the safe assembly of the gate frame in front of the door opening in the door leaf assembly area, facilitates the subsequent hoisting of the gate frame, and has a reasonable zoning, which helps to improve construction efficiency and construction safety. It is suitable for the assembly and hoisting of various large gates. Attached Figure Description

Detailed Implementation

[0050] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0051] A method for assembling and constructing a hangar door includes the following steps:

[0052] Step 1: Site preparation, on-site construction work area 1.

[0053] Please see the appendix Figure 1 The on-site construction work area 1 includes a construction passage 101, a temporary track storage area 102, a door assembly area 103, and a temporary door component storage area 104. The door assembly area 103 is located outside the door opening of the hangar gate, and the temporary door component storage area 104 is located beside the door assembly area 103, forming an assembly site. The temporary track storage area 102 is located along one side of the assembly site, and the construction passage 101 is located along the side of the temporary track storage area 102 away from the assembly site.

[0054] Preferably, the construction access road 101 is 6m wide, for the entry and exit of transport vehicles and mobile cranes. The temporary storage area 102 and the temporary storage area 104 for door panel components are hardened semi-finished product storage areas.

[0055] A typical hangar structure consists of multiple independent hangar bays, each requiring a hangar door. Therefore, with the door openings spaced apart, multiple door assembly areas 103 are needed. Preferably, the multiple door assembly areas 103 and multiple temporary storage areas 104 for door components are arranged alternately. The temporary storage areas 104 are used to store door components from adjacent assembly areas, facilitating the assembly of hangar doors within the assembly areas 103. The number of door assembly areas 103 and the number of temporary storage areas 104 can be adjusted adaptively according to the workload of the project.

[0056] The length of the door assembly area 103 is 1 times the height of the hangar door, and the width of the door assembly area 103 is the same as the width of the hangar. The door assembly area 103 is a hardened assembly site, and each door assembly area 103 can be adapted to the size of the hangar door.

[0057] A 380V construction power supply should be provided within 30m of the center of the hangar door opening, and the power consumption of the construction power supply should not be less than 20kW, to provide working power for the drive and electrical systems of the assembly construction and subsequent installation.

[0058] Step 2: Install the upper track system at the top of the hangar door opening and the lower track system at the bottom of the door opening.

[0059] The aforementioned upper track system includes an upper track bracket and a gate upper track. The installation method for the upper track system is as follows: The gate upper track is laid flat on the ground beam using a 25-ton truck crane; the upper track bracket is then installed onto the gate upper track to form the upper track system; next, four electric hoists are used to vertically lift the upper track system to the lower chord steel beam under the gate head beam, and the upper track bracket is placed on the lower chord steel beam under the gate head beam, ensuring a secure weld.

[0060] Preferably, the upper track of the gate is configured according to the size and shape of the hangar door, serving to guide the opening and closing of the hangar door and ensure smooth operation. The upper track support can be a steel structure support, used to install the upper track of the gate onto the lower chord steel beam under the gate head beam. The structural form of the upper track support can be adaptively adjusted according to actual installation requirements and load-bearing requirements.

[0061] The lower track system includes track fixing components, a lower gate track, a slope protection structure, and a drainage outlet frame. The installation method for the lower track system is as follows: Track fixing components are laid on the poured ground beam using temporary fixing bolts. After adjusting the horizontal position of the track fixing components, they are fixed to the ground beam. Track clamps are used to fix the lower gate track to the track fixing components. The slope protection structure is installed between the track fixing components and the ground on both sides. Finally, the drainage outlet frame is installed and connected to the drainage system.

[0062] Preferably, the track fixing components can be made of 12.6 channel steel, and the deviation between the rail top height and the design height of the track fixing components should be less than ±1mm. The slope protection can be made of angle steel, and the slope protection is fixed between the track fixing components and the ground through angle iron connectors to ensure that the slope protection is firmly installed and provides reliable protection for the track under the gate. The drainage outlet frame can be adapted to the configuration and location of the hangar drainage system, and is used to guide the water accumulated at the lower track through the drainage outlet frame into the hangar drainage system.

[0063] Step 3: Assemble the gate frame on the on-site construction work surface 1.

[0064] Step 3 includes the following sub-steps:

[0065] Step 3.1: Install the left mullion 201, right mullion 202, and center mullion 203 respectively in the door assembly area 103, as shown in the attached diagram. Figure 2As shown, the length of the left mullion 201, the right mullion 202, and the middle mullion 203 are all set along the length of the door assembly area 103 of the on-site construction work surface 1 where they are located. The left mullion 201, the middle mullion 203, and the right mullion 202 are arranged from left to right along the width of the door assembly area 103, ensuring that the assembled hangar door is located in the door assembly area 103 outside the hangar door opening.

[0066] When installing the left mullion 201, right mullion 202, and center mullion 203, due to the considerable height of the hangar door, the upper half of the left mullion 201 can be installed first, followed by the lower half, and finally the upper and lower halves can be connected to form the left mullion 201. The right mullion 202 and center mullion 203 are installed using the same method, which will not be described in detail here.

[0067] Step 3.2: Install the upper stile 204 at the top of the left stile 201, right stile 202, and middle stile 203; install the lower stile 205 at the bottom of the left stile 201, right stile 202, and middle stile 203, as shown in the attached diagram. Figure 3 As shown.

[0068] The left mullion 201, right mullion 202, top mullion 204, and bottom mullion 205 constitute the frame structure of the door, while the middle mullion 203 is located at the center line of the door frame to ensure the strength of the frame structure.

[0069] Step 3.3: Install the upper mullion component 2041 on the top of the upper mullion 204, and install the lower mullion component 2051 on the top of the lower mullion 205, as shown in the attached diagram. Figure 4 As shown.

[0070] The upper mullion component 2041 is used for subsequent installation of the upper guide wheel that slides in conjunction with the upper track of the gate, and the lower mullion component 2051 is used for subsequent installation of the lower guide wheel that slides in conjunction with the lower track of the gate.

[0071] Step 3.4: Install a first rigid support 2042 between the upper stile component 2041 and the left stile 201 and right stile 202 on both sides of the gate frame, and install a second rigid support 2052 on the lower stile component 2051, as shown in the attached figure. Figure 5 As shown.

[0072] The first rigid support 2042 is used to improve the structural strength of the upper mullion component 2041 and the corner of the frame, and the second rigid support 2052 is used to improve the structural strength of the lower mullion component 2051 and prevent deformation under stress.

[0073] Step 3.5: Install several horizontal wind-resistant beams 206 at intervals between the upper mullion 204 and the lower mullion 205. The horizontal wind-resistant beams 206 are vertically connected to the left mullion 201, the right mullion 202, and the middle mullion 203, as shown in the attached diagram. Figure 6 As shown.

[0074] The horizontal wind-resistant beam 206 is used to improve the wind resistance of the hangar door. The horizontal wind-resistant beam 206 can be made of square steel or shaped steel. The number, spacing and specifications of the horizontal wind-resistant beam 206 can be adjusted according to the wind conditions of the installation area.

[0075] Step 3.6: Vertically install several secondary wind-resistant columns 207 between the upper mullion 204 and the lower mullion 205, with the secondary wind-resistant columns 207 vertically connected to the horizontal wind-resistant beam 206; install skirt brackets 208 between the lower mullion 205 and the left mullion 201 and the right mullion 202, as shown in the attached diagram. Figure 7 As shown.

[0076] Secondary wind-resistant columns 207 are used to further improve the wind resistance of the hangar doors. The secondary wind-resistant columns 207 can be made of square steel or shaped steel. The number, spacing and specifications of the secondary wind-resistant columns 207 can be adjusted according to the wind conditions of the installation area.

[0077] The skirt bracket 208 facilitates the installation of the hangar door skirt. The skirt bracket 208 is constructed from a steel structure and can be installed adaptably according to the design position of the hangar door skirt.

[0078] Step 3.7: The diagonal support 209, which has an X-shaped structure, is arranged roughly along the diagonal of the gate frame, as shown in the attached diagram. Figure 8 As shown.

[0079] Preferably, the diagonal support 209 can be made of round steel pipe. The diagonal support 209 is arranged diagonally along the upper mullion 204, lower mullion 205, horizontal wind-resistant beam 206, left mullion 201, right mullion 202, central mullion 203, and secondary wind-resistant column 207 to form a rectangular cell. A shorter diagonal support 209 can be added to the lower part of the gate frame to improve the support effect of the diagonal support 209 and ensure the structural strength and load-bearing capacity of the gate frame.

[0080] Step 3.8: Install several panel beams 210 at intervals on the front of the gate frame, as shown in the attached diagram. Figure 9 As shown.

[0081] Preferably, the panel beams 210 can be arranged in parallel between the upper mullion 204 and the lower mullion 205. The panel beams 210 can be made of steel keel. The number and spacing of the panel beams 210 can be adjusted according to the size of the glass curtain wall to be installed later.

[0082] Step 3.9: Install the sealing plate frame 211 on the top of the upper mullion 204, as shown in the attached diagram. Figure 10 As shown.

[0083] The sealing plate frame 211 facilitates the subsequent installation of the sealing plate 212 on the top of the gate frame. The sealing plate frame 211 can be adapted to the actual installation requirements of the sealing plate 212.

[0084] Step 3.10: Install the sealing plate 212 onto the top of the gate frame using the sealing plate frame 211, as shown in the attached diagram. Figure 11 As shown.

[0085] During the assembly of the gate frame, the connection nodes of the upper mullion 204, lower mullion 205, horizontal wind-resistant beam 206, left mullion 201, right mullion 202, central mullion 203, and secondary wind-resistant column 207 can be assembled by bolting or riveting. There should be no loosening or deformation at the connection nodes. The panel beam 210 is assembled onto the gate frame by welding. The surface of the panel beam 210 is flat, and the weld should not have defects such as cracked welds. The weld quality should not be lower than the Class II standard specified in GB 50017.

[0086] Step 4: Hoist the gate frame.

[0087] Step 4 includes the following sub-steps:

[0088] Step 4.1: The upper guide wheels of the hangar door are pre-installed onto the upper track of the upper track system. Preferably, the upper guide wheels can be installed using a truck crane.

[0089] Step 4.2: Hoist the gate frame to the door lifting area at the hangar gate opening. Preferably, the gate frame can be hoisted into place using a truck crane.

[0090] Step 4.3: Slowly insert the upper part of the gate frame into the guide space of the gate's upper track. Preferably, the gate frame can be lifted into place using a truck crane.

[0091] Step 4.4: Place the bottom of the gate frame onto the corresponding lower track of the gate lower track system.

[0092] Step 4.5: Install the upper guide wheel onto the upper stile component 2041 of the gate frame, and install the lower guide wheel onto the lower stile component 2051 of the gate frame, ensuring that the gate frame can slide stably along the upper and lower guide rails of the gate after installation.

[0093] Step 5: Install the panel, trim, drive and electrical systems to complete the installation of the hangar door.

[0094] Preferably, the panel can be made of insulated glass, which has good light transmission effect. The installation method of the panel is as follows: wipe the panel surface clean, use a manual suction cup to adsorb it to avoid air leakage and ensure construction safety. The position of the coating layer of the insulated panel should meet the design requirements. Two positioning rubber blocks (silicone building sealant) should be set at the bottom of the component frame groove for installing the panel. The embedding amount and gaps around the panel should meet the requirements, and the gaps on the left and right sides should be consistent. Rubber strips (silicone building sealant) are set at the contact points between the inner and outer aluminum profiles and the panel. This allows the panel to slide vertically and horizontally under the clamping of the rubber strips when the door frame deforms or the temperature deforms, eliminating the adverse effects of deformation on the panel.

[0095] The application of silicone building sealant must be strictly carried out in accordance with the construction process. For example, sealant should not be applied at night when there is insufficient light or when the joints are damp due to heavy rain. The application temperature should be within the specified temperature range. The surface to be sealed should be dry, clean and dust-free before application.

[0096] The gate frame is finished with color steel plates, which ensure reliable fixation and a smooth, even installation of the fireproof and insulation materials. The laying and finishing of the fireproof and insulation materials can be done using conventional techniques, which will not be elaborated here. When finishing the edges, care should be taken to ensure no gaps are left at the joints to meet design requirements.

[0097] After the color steel panels are installed, the surfaces of the gate frame, color steel panels, and other steel materials should be treated with painting, spraying, or other processes according to durability requirements. The total thickness of the dry paint film should not be less than 125µm. The coating should be firm and durable. In coastal areas and other regions with special anti-corrosion and moisture-proof requirements, the adhesion should not be lower than level 4.

[0098] The drive and electrical systems can be installed using existing drive and electrical equipment according to the opening and closing drive and control requirements of the hangar door. Preferably, the hangar door can be opened and closed using a safety jog button mode, and can be opened automatically in the event of a fire. A touch screen device is selected to control the hangar door, and the touch screen interface should be able to directly display the door status and the alarm status of each monitoring point.

[0099] Preferably, the drive and electrical system may include, but is not limited to, the following functions:

[0100] 1. The braking system is sensitive; under normal operation, the hangar door should be able to stop at any position.

[0101] 2. The limit device is reliable. Under normal operation, the hangar door should be able to be limited to the set position by the limit device.

[0102] 3. The main gate of the electric motor storage area should be equipped with a manual / electric conversion interlock device.

[0103] For sliding hangar doors, a larger door leaf structure is formed by upper, lower, left, right, and middle mullions. For side-turning and top-loading hangar doors, a smaller door leaf structure is formed by upper, lower, left, right, and middle mullions. Adjacent door leaves are hinged together to form the hangar door, in order to meet different opening and closing modes of the hangar door.

[0104] 4. The wheels of sliding hangar doors should be equipped with anti-derailment devices.

[0105] 5. Push-pull and side-turn hangar doors should be equipped with limit devices that can effectively block the hangar doors in the event of a malfunction in the pneumatic control system, preventing collisions and derailment.

[0106] 6. Audible and visual alarms should be installed at a height of 1.5m-2.5m on both sides of the door opening, providing an audible and visual warning 5-10 seconds before the hangar door is opened. For sliding hangar doors, an operation warning light should be installed at a height of 15m-2.5m on each door leaf.

[0107] 7. The top-mounted hangar door should be equipped with a door leaf anti-fall device. In the event of a malfunction in the door leaf lifting device, the door leaf anti-fall device should be automatically triggered to ensure that the door leaf can stop and be locked when it descends or slides a distance of no more than 200mm.

[0108] 8. When a movable column is used as a combination door frame for the door opening, a column anti-fall device should be installed. If the movable column suddenly falls, the movable column anti-fall device should activate, and the movable column should be able to lock when it falls no more than 100mm.

[0109] 9. Electric sliding hangar doors should be equipped with both contactless and contactless sensors. Contactless sensors should be able to instruct the hangar door to stop when an obstacle is detected; contactless sensors should be able to detect an obstacle 1m in front of the hangar door and stop the hangar door at a distance of not less than 100mm from the obstacle.

[0110] 10. An emergency stop button should be provided on the control box.

[0111] 11. When a small door is opened in the main gate of the hangar, an interlocking device for opening and closing the main door and the small door should be installed.

[0112] The drive and electrical systems are not part of the assembly of the hangar door steel structure and can be configured according to the requirements of the actual application functions, which will not be elaborated here.

[0113] Step 6: Run and test the hangar gate.

[0114] After the hangar door is installed, it should be repeatedly run and tested to check the condition of each component and the whole system. At this stage, the relevant parties should be notified to provide formal power to the hangar door. If formal power supply is not possible, at least ensure that the hangar door has a separate power supply. Otherwise, the instability of the construction power supply will affect the service life of the electrical components of the hangar door and may even damage the control board of the drive and electrical system. The maintenance and construction of the hangar door beam truss should be carried out after the completion of the upper rail, sliding contact line and electrical construction. Construction at the joint of the door too early will bring certain difficulties to the construction of the hangar door, upper rail, sliding contact line and electrical system, and may even make some work impossible to carry out.

[0115] When operating and testing the hangar door, all hardware installed on the hangar door should not move during repeated door movement; any hardware that moves repeatedly should be replaced.

[0116] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
