Abstract
Description
Technical Field
[0001] The present invention relates to the field of building decoration technology, in particular to a construction method for roof decoration in a large-span building. Background Art
[0002] Large-span buildings such as stadiums, exhibition halls, and airport terminals typically have roof structures with large spans, high heights, and complex structures. Traditional roof decoration construction methods face significant challenges in terms of high-altitude work, material transportation, and construction accuracy. In recent years, with the advancement of construction technology, the number of large-span buildings has continued to increase, placing higher demands on the efficiency, safety, and quality of roof decoration construction. Currently, the industry mainly uses scaffolding, aerial work vehicles, or hanging baskets for construction. In the existing technology, the following methods are mainly used for the decoration and construction of large-span building roofs: The first method is to erect a full-floor scaffolding. This method can provide a stable working platform, but it takes a long time to erect, consumes a lot of materials, and is costly. The second method is to use an aerial work vehicle or hanging basket. This method has high flexibility, but the operating range is limited and there are safety hazards. The third method is to use a mobile lifting platform. This method is suitable for local construction, but the overall construction efficiency is low for large-span roofs. In addition, the above methods are not convenient for transporting materials. Full-floor scaffolding and mobile lifting platforms generally lift materials from the ground to the construction platform by adding lifting equipment, but the materials can only be placed at fixed points on the platform, and manual work is required to move the materials on the platform; aerial work vehicles or hanging baskets load materials by descending to the ground, and then lift the height for operation. A small amount of material can be placed at one time, and frequent lifting operations are required, resulting in low construction efficiency. Summary of the Invention

[0010] Preferably, vertical rails are vertically installed on both the front and rear sides of the vertical mounting frame, and the front and rear sides of the lifting frame slide vertically along the vertical rails respectively.
[0011] Preferably, a second slide rail aligned with the slide rail is installed on the bottom end surface of the lifting frame.
[0012] Preferably, an infrared receiver 2 is further installed at the bottom end of the lifting frame, and an infrared transmitter 2 is used to receive infrared light signals emitted by the infrared transmitter at the bottom of the transport trolley to monitor whether the transport trolley is completely located in the lifting frame.

[0016] The following will be combined with the Figure 1-10 The present invention is described in detail and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention. Figure 1-10 The invention provides a method for roof decoration and construction of a large-span building, comprising the following steps: Step S1: Install the truss assembly 1: Step S11: Install the main trusses 11 along the roof span direction. The main trusses 11 are connected in sections via connectors 12. Sockets are provided on both sides of the connectors 12 to fit the main trusses 11. The ends of the main trusses 11 are inserted into the sockets of the connectors 12 and secured with bolts. Step S12: Arrange the secondary truss 13 in a direction perpendicular to the main truss 11, and the top of the secondary truss 13 is fixedly connected to the connecting head 12 by bolts. Install the support rod 14 at the intersection node of the main truss 101 and the secondary truss 103, and the two ends of the support rod 14 are respectively locked and connected to the side walls of the main truss 11 and the secondary truss 13 by bolts.
[0017] Step S13 : installing the fence 15 at the top edge of the main truss 11 .
[0018] Step S2: Deploy the transport trolley assembly 2: Step S21: Fix two slide rails 22 parallel to the main truss 11. The slide rails 22 are arranged parallel to the main truss 11. An infrared receiver 23 is installed equidistantly between the two rails 22. A wireless charging transmitter module 24 is installed at the end between the two slide rails 22. Step S22 : Deploy the transport trolley 21 on the slide rail 22 . The transport trolley 21 is equipped with an infrared transmitter 215 , a wireless charging receiving end module 216 , a driving component 218 , an angle sensor 219 and a battery 2110 .
[0019] What needs to be explained in step 2 is: The transport trolley 21 has a frame 211 with a driving wheel set 212 and a driven wheel set 213 on the left and right sides of the bottom. A control box 217 is installed on the frame 211. A drive assembly 218, an angle sensor 219, a battery 2110, and a controller 2111 are installed in the control box 217. The transport trolley 21 is equipped with a bucket 2112, which is mounted on a control box 217. The bucket 2112 is used to load decoration materials. The transport trolley 21 is also equipped with a brake 214 and a controller 2111. The brake 214 is used to brake the driving wheel set 212 of the transport trolley 21. The controller 2111 is equipped with a processor for data calculation. The wireless charging transmitter module 24 wirelessly charges the battery 2110 through the wireless charging receiver module 216. The driving assembly 218 is used to drive the active wheel group 212 of the transport trolley 21 to move along the slide rail 22. The driving assembly 218 includes a driving motor 2181, a reducer 2182, a transmission shaft 2183 and a synchronous wheel group 2184. The output end of the driving motor 2181 is transmission-connected to the input end of the reducer 2182, the output end of the reducer 2182 is transmission-connected to the transmission shaft 2183, the other end of the transmission shaft 2183 is transmission-connected to the input end of the angle sensor 219, and the transmission shaft 2183 is transmission-connected to the rotating shaft of the active wheel group 212 through the synchronous wheel group 2184. The angle sensor 219 is used to monitor the moving direction and moving stroke of the transport trolley 21. The infrared receiver 23 and the infrared transmitter 215 are used to calibrate the moving stroke of the transport trolley 21 monitored by the angle sensor 219. When the transport trolley 21 moves, the infrared transmitter 215 passes through the infrared receiver 23, and the infrared receiver 23 is used to receive the infrared light signal emitted by the infrared transmitter 215. Mounting slots are equidistantly installed in the middle of the top of the main truss 11. The mounting slots are used to install infrared receivers 23. The installation positions of the infrared receivers 23 are preset, and there is no need to manually measure the spacing of the infrared receivers 23, which results in deviations in the installation positions of the infrared receivers 23. The distance between the wireless charging receiving end module 216 and the nearest infrared receiver 23 is consistent with the distance between the infrared transmitter 215 at the bottom of the transport trolley 21 and the wireless charging receiving end module 216. When the transport trolley 21 is charging, when the wireless charging receiving end module 216 of the transport trolley 21 moves to align with the position of the wireless charging transmitting end module 24, the infrared receiver 23 closest to the wireless charging transmitting end module 24 receives the infrared light signal emitted by the infrared transmitter 215 at the bottom of the transport trolley 21, ensuring that the positions of the wireless charging receiving end module 216 and the wireless charging transmitting end module 24 correspond to each other. The infrared receiver 23 and infrared transmitter 215 use SICK WTB4S-P compact through-beam sensors, which have strong anti-interference performance and fast response speed. The angle sensor 219 adopts the model of Tamagawa TS5700N, which has an absolute encoder and a power-off position memory function. The angle sensor 219 is rigidly connected to the driving wheel set 212 of the transport trolley 21 through the transmission shaft 2183 and the synchronous wheel set 2184. The angle sensor 219 measures the number of rotations and the rotation angle of the transmission shaft 2183 in real time, and calculates the travel of the transport trolley 21 based on the number of rotations and the rotation angle of the transmission shaft 2183. Due to the sliding phenomenon of the driving wheel set 212 and the driven wheel set 213 during the braking process and the accumulated error of the angle sensor, it is necessary to calibrate the angle sensor 219 and also check whether the calculation of the number of rotations and the rotation angle into the travel is correct. Since the distance between the two infrared receivers 23 is fixed, when two adjacent infrared receivers 23 receive an infrared light signal, the distance between the two infrared receivers 23 is used as the basis for calibrating the movement distance of the transport trolley 21 monitored by the angle sensor 219 when the two infrared receivers 23 are triggered, and when the infrared receivers 23 are triggered, the position of the transport trolley 21 on the main truss 11 is determined.
[0020] The wireless charging transmitter module 24 and the wired charging receiver module 216 are mature wireless charging technologies and will not be described in detail. The drive motor 2181 adopts a Siemens 1FK7 servo motor, which is matched with a reducer and supports high torque output to meet the power required by the transport trolley 21 to transport materials; The brake 214 is used to brake the driving wheel set 212. The brake 214 is a mature existing technology and will not be described in detail.
[0021] Step S3: Installing the lifting device 3: The vertical mounting frame 31 of the lifting device 3 is vertically mounted on the end of the truss assembly 1, and the top opening 37 on the vertical mounting frame 31 is aligned with the direction of the slide rail 22. An electric hoist 34 is installed on the top of the lifting device 3, and the electric hoist 34 is used to control the lifting of the lifting frame 32; Vertical rails 33 are vertically installed on the front and rear sides of the vertical mounting frame 31. The front and rear sides of the lifting frame 32 slide vertically along the vertical rails 33 respectively. The vertical rails 33 guide the movement of the lifting frame 32 to increase the smooth movement of the lifting frame 32. The bottom end surface of the lifting frame 32 is equipped with a second slide rail 35 aligned with the slide rail 22. The bottom end of the lifting frame 32 is also equipped with a second infrared receiver 36. The second infrared transmitter 36 is used to receive the infrared light signal emitted by the infrared transmitter 215 at the bottom of the transport trolley 21 to monitor whether the transport trolley 21 is completely located in the lifting frame 32. What needs to be explained in step 3 is that: after the lifting frame 32 is lifted, the second slide rail 35 is connected with the slide rail 22, and the driving wheel group 212 and the driven wheel group 213 of the transport trolley 21 travel onto the second slide rail 35 through the slide rail 22, and the second infrared emitter 36 in the lifting frame 32 receives the infrared light signal emitted by the infrared emitter 215 at the bottom of the transport trolley 21, and it is determined that the transport trolley 21 is completely placed in the lifting frame 32, and the electric hoist 34 is started to control the lifting frame 32 and the transport trolley 21 to rise and fall, and a bottom opening 38 is provided at the bottom left side of the vertical frame 31, and a support plate is provided at the bottom left end of the bottom opening 38, and a slide rail is provided on the support plate. After the transport trolley 21 descends to the bottom, it can travel onto the support plate, which is conducive to loading materials; The electric hoist 34 adopts the Konecranes GH-E series, with variable frequency control and smooth lifting, which is suitable for precision construction. The drive shaft of the electric hoist 34 is equipped with an angle sensor to monitor the lifting and lowering height of the lifting frame 32, and is conducive to controlling the height of the lifting frame 32, and facilitating the alignment of the slide rail 235 of the lifting frame 32 with the slide rail 22 on the main truss 11.
[0022] Step S4: Construction work: Construction workers carry out decoration and renovation work on the main truss 11, and control the lifting and lowering of the transport trolley 21 through the lifting device, and transport the decoration materials on the ground to the main truss 11 through the transport trolley 21. The transport trolley 21 moves along the slide rail 22 on the main truss 11 to transport the materials to the target coordinates.
[0023] Step S5: After construction is completed, the truss assembly 1, the conveyor trolley assembly 2, and the lifting device 3 are removed. The above shows and describes the basic principles, main features, and advantages of the present invention. The standard parts used in the present invention can be purchased from the market, and special-shaped parts can be customized according to the description and drawings.
