[0028] The present application also provides a method for constructing the above-mentioned steel structure special-shaped metal roof inverted ceiling sliding device, comprising the following steps: Step 1: Hang the steel structure special-shaped metal roof reverse ceiling sliding device to the preset position of the roof, and fix the first platform 110 and the second platform 120 of the steel structure platform 100 on the end steel pipes 310 at both ends of the truss 300 through the sliding clamps 160. Specifically, first rotate the first connecting shaft 161 to drive the first clamp 162 to rotate until the bottom opening is aligned with the end steel pipe 310, then rotate the nut connected to the first locking bolt 163 to separate the first locking bolt 163 from the first clamp 162, and then The first clamp 162 is placed on the end steel pipe 310 of the truss 300 through the bottom opening. Finally, the first locking bolt 163 is re-entered through the first clamp 162 and the connecting nut is tightened at both ends of the bottom of the first clamp 162. The construction worker lies on his back on the top surface of the platform vehicle 200 and is secured with a safety belt 230. He presses the steel structure platform 100 with his feet to move the platform vehicle 200 along the first track 140 and the second track 150 on the first platform 110 and the second platform 120 via the four wheels 210 connected at the bottom to perform construction. In order to ensure the stability of the sliding device for the special-shaped metal roof with a steel structure, the middle clamp 170 connected to the bottom of the rotating shaft 130 can also be sleeved and fixed on the inclined steel pipe 320 connected at both ends of the truss 300. Specifically, first rotate the second connecting shaft 171 to align the bottom opening of the second clamp 172 with the inclined steel pipe 320, then rotate the nut connected to the second locking bolt 173 to separate the second locking bolt 173 from the second clamp 172, and then sleeve the second clamp 172 on the inclined steel pipe 320 of the truss 300 through the bottom opening, and finally re-install it. The second locking bolt 173 passes through the second clamp 172 and the connecting nut locks the two ends of the bottom of the second clamp 172, so that the first platform 110 and the second platform 120 are fixedly mounted on the end steel pipes 310 at both ends of the truss 300 through the sliding clamp 160. At the same time, the middle clamp 170 connected to the bottom of the rotating shaft 130 is further mounted and fixed on the inclined steel pipe 320 of the truss 300 to achieve three-point connection and locking, ensuring that the steel structure special-shaped metal roof inverted ceiling sliding device is stably fixed on the truss 300, effectively improving the safety of construction workers.
[0029] Step 2. When it is necessary to adjust the position of the sliding device of the steel structure special-shaped metal roof anti-ceiling, rotate the nuts connected by the two first locking bolts 163 respectively to loosen the two ends of the first clamps 162 of the two sliding clamps 160, slide the two sliding clamps 160 along the two corresponding end steel pipes 310, and then rotate the nuts connected by the two first locking bolts 163 again to lock the first clamps 162 of the two sliding clamps 160, and fix the two sliding clamps 160 to the corresponding end steel pipes 310.
[0030] Step 3: Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, when it is necessary to translate the steel structure special-shaped metal roof reverse ceiling sliding device to the purlin 330 that passes over the truss for operation, the following steps are included: 3.1. Fix the middle clamp 170 connected to the bottom of the rotating shaft 130 to the inclined steel pipe 320 of the truss 300; 3.2. Rotate the nut connected to the first locking bolt 163 on the sliding clamp 160 of the second platform 120 at the bottom to separate the first locking bolt 163 from the first clamp 162, and separate the sliding clamp 160 of the second platform 120 at the bottom from the end steel pipe 310 at the bottom. Then, rotate the second platform 120 relative to the first platform 110 and rotate the two fixing bolts 113 on both sides of the second platform 120 to stop locking the position of the platform plug-in plate 112 of the second platform 120, drive the platform plug-in plate 112 of the second platform 120 to extend out of the corresponding platform sleeve 111, so that the platform plug-in plate 112 of the second platform 120 extends through Pass under the purlin support 330, then re-rotate the two fixing bolts 113 on both sides of the second platform 120 to re-press and lock the position of the platform plug plate 112 of the second platform 120, and re-fix the sliding clamp 160 provided at the bottom of the platform plug plate 112 of the second platform 120 to the end steel pipe 310 below. Specifically, rotate the first connecting shaft 161 to re-sleeve the first clamp 162 on the sliding clamp 160 of the second platform 120 located below onto the end steel pipe 310 below, insert the first locking bolt 163 into the two ends of the bottom of the first clamp 162 on the sliding clamp 160 of the second platform 120, and then connect the nuts to lock; 3.3. Rotate the first platform 110 and the second platform 120 and simultaneously extend the first platform 110 and retract the second platform 120, so that the platform inserting plate 112 of the first platform 110 extends out of the corresponding platform sleeve 111. The rotating shaft 130 at the connection between the first platform 110 and the second platform 120 drives the middle clamp 170 at the bottom to move over the purlin support 330 to the top of the other inclined steel pipe 320, and then fix the middle clamp 170 to the other inclined steel pipe 320. 3.4. Separate the sliding clamp 160 of the first platform 110 from the corresponding end steel pipe 310, then rotate and retract the first platform 110 so that the first platform 110 passes through the purlin support 330, and re-fix the sliding clamp 160 of the first platform 110 to the end steel pipe 310, completing the translation of the steel structure special-shaped metal roof inverted ceiling sliding device to the purlin support 330 that passes over the truss, so that the construction workers can continue the roof construction work.
[0031] The steel structure special-shaped metal roof inverted ceiling sliding device and construction method provided in the embodiment of the present application support construction workers through the provision of a steel structure platform 100 detachably connected to the two ends of the truss 300 on the roof and a platform vehicle 200 slidingly arranged on the top surface of the steel structure platform 100. The steel structure platform 100 is composed of a retractable first platform 110 and a second platform 120 that are rotatably connected in the middle by a rotating shaft 130. The ends of the first platform 110 and the second platform 120 that are away from each other are respectively provided with sliding clamps 160 for detachably connecting the end steel pipes 310 of the two ends of the truss 300. The rotating shaft 130 at the connection between the first platform 110 and the second platform 120 is provided with a middle clamp 170 for connecting the oblique steel pipe 320 in the middle of the truss 300. On the one hand, the first platform 110 and the second platform 120 are retractably and rotatably connected. The platform 110 and the second platform 120 as well as the sliding clamp 160 and the middle clamp 170 increase the position adjustment flexibility of the steel structure platform 100, so that it can slide and adjust the construction position flexibly, solving the problem that the steel platform cannot rotate and move, improving the work efficiency of the operators, and at the same time enhancing the stability and safety of the steel platform, so that the operators can remain stable during the movement, reducing the safety hazards caused by shaking or tilting, solving the problems of small working space, difficult construction, and poor flexibility, and improving the work efficiency of the operators. On the other hand, it can facilitate the construction workers to adjust their positions to bypass the purlins of the truss to perform operations, so that the operators can adjust their positions to perform operations in complex environments, reducing the risks of high-altitude operations caused by repeated moving and adjustment of the steel structure platform.
[0032] In addition, by providing an electromagnet 260 in the wheel 210, the electromagnet 260 is used to drive the wheel 210 to magnetically absorb or detach from the steel structure platform 100; the controller 250 is used to receive data detected by the acceleration sensor 240 and control the electromagnet 260 to drive the wheel 210 to magnetically absorb or detach from the steel structure platform 100. The controller 250 can be used to receive data detected by the acceleration sensor 240 and control the electromagnet to drive the wheel 210 to be magnetically absorbed and fixed to the steel structure platform 100, thereby avoiding safety accidents. Construction personnel can also actively control the electromagnet 260 to drive the wheel 210 to be magnetically absorbed on the steel structure platform 100 to improve construction safety.
