The first vertical support rod 1 and the second vertical support rod 2 are symmetrically arranged at a certain angle. Several horizontal bars 3 are welded at equal intervals to the inner side ends of the first vertical support rod 1 and the second vertical support rod 2. Horizontal hinged connecting rods 5 are hinged to the bottom of the side of the first vertical support rod 1 and the second vertical support rod 2. Horizontal hinged treads 6 are hinged to the top of the inner side of the first vertical support rod 1 and the second vertical support rod 2.

[0028] The top ends of the first vertical support rod 1 and the second vertical support rod 2 are both connected to a top extension rod 4, and the bottom of the second vertical support rod 2 is connected to a bottom extension rod 7. The ends of the top extension rod 4 and the bottom extension rod 7 are respectively connected to telescopic inner rods 8 that slide along the inner side of the first vertical support rod 1 and the second vertical support rod 2. Several adjustment holes 9 are equidistantly opened on the side of the telescopic inner rod 8, and the sides of the first vertical support rod 1 and the second vertical support rod 2 are connected to the adjustment holes 9 through limiting bolts 10. The middle parts of the horizontal hinge connecting rod 5 and the horizontal hinge pedal 6 are respectively hinged together through hinge seats, and the folding angle of the horizontal hinge connecting rod 5 and the horizontal hinge pedal 6 is 0 to 180 degrees, which facilitates the hinged connection of the horizontal hinge connecting rod 5 and the horizontal hinge pedal 6, facilitates the rapid formation of a platform structure on the top of the first vertical support rod 1 and the second vertical support rod 2, and makes the horizontal hinge connecting rod 5 and the horizontal hinge pedal 6 easy to fold, making the work platform convenient to put away and take away.

[0029] The top end of the second vertical support rod 2 is fixedly connected to a fixing chain 11, and the top end of the first vertical support rod 1 is fixedly connected to a snap-fit ​​seat 12. The fixing chain 11 is detachably snap-fitted to the snap-fit ​​seat 12 through the buckle 13 at its end.

[0030] A hook block 14 is provided on the top extension rod 4 on the side of the second vertical support rod 2, and a placement box 15 is connected to one side of the top extension rod 4. The placement box 15 is connected to the hook block 14 by the hanging block 16 at its edge. The edge of the placement box 15 fits against the side of the top extension rod 4. The hanging block 16 and the hook block 14 are connected by hooking. The hook block 14 and the hanging block 16 make it more convenient to hang the placement box 15 in actual use, making it easier to pick up and place the placement box 15 stably. Inner partitions 17 are installed at equal intervals on the inner side of the placement box 15.

[0031] Three sets of limiting brackets 18 are equidistantly connected to the bottom end of the crossbar 3 at the bottom position of the horizontal hinged pedal 6. The inner side of the limiting bracket 18 fits and engages with the limiting plate 19. The end of the limiting plate 19 is fixedly connected to the horizontal support strip 20, and the top of the limiting plate 19 is provided with the anti-slip rubber block 21. The horizontal support strip 20 is connected to the limiting bracket 18 through the limiting plate 19 at its end. The horizontal support strip 20 is in close contact with the bottom surface of the horizontal hinged pedal 6, and the anti-slip rubber block 21 is in close contact with the inner side of the limiting bracket 18, which facilitates the quick engagement of the horizontal support strip 20. The anti-slip rubber block 21 ensures the tightness of the connection and ensures that the horizontal support strip 20 can provide stable support for the bottom of the horizontal hinged pedal 6, thereby strengthening the support strength of the horizontal hinged pedal 6.

[0032] The working principle and usage process of this utility model: In actual application, the convenient working platform mechanism for ceiling construction in stairwell is first unfolded and placed on the stair steps. The adjustable bottom extension rod 7 connected to the bottom of the second vertical support rod 2 makes it easy to adjust the support position of the bottom of the second vertical support rod 2, so that the working platform can also be stably supported on the stair steps through adjustment.

[0033] Meanwhile, by connecting the top of the first vertical support rod 1 and the second vertical support rod 2 to the top of the telescopic and adjustable top extension rod 4, it is convenient to adjust the extension length of the top of the first vertical support rod 1 and the second vertical support rod 2, so as to adjust the enclosure space formed on the top of the platform according to the needs, and to make it easy to be flexibly applied according to actual needs, and to facilitate the construction of the stairwell ceiling. In addition, during the telescopic adjustment of the top extension rod 4 and the bottom extension rod 7, the position of the telescopic inner rod 8 at the end of the top extension rod 4 and the bottom extension rod 7 is adjusted, and then the position of the telescopic inner rod 8 is limited by the limit bolt 10 and the adjustment hole 9, so as to adjust the extension length of the top extension rod 4 and the bottom extension rod 7.

[0034] Next, by combining the horizontal hinged connecting rod 5 and the horizontal hinged tread 6 with their internal hinged connection, a working platform for the construction of the stairwell ceiling can be quickly and easily assembled. The horizontal hinged connecting rod 5 and the horizontal hinged tread 6 are easy to fold, making the working platform convenient to put away and put away and stable to use. Workers can climb up to the horizontal hinged tread 6 via the crossbar 3, and then form a top protection component by connecting the fixed chain 11 to the top of the platform. When connecting the fixed chain 11, the fixed chain 11 can be quickly connected and disassembled through the snap-fit ​​seat 12 and the buckle 13, making the fixed chain 11 easy to operate during the disassembly and assembly process and improving the safety factor of the workers.

[0035] During the construction work, the limiting bracket 18 set on the bottom crossbar 3 of the horizontal hinged pedal 6, combined with the limiting plate 19 and the anti-slip rubber block 21, facilitates the quick snap-fit ​​connection of the horizontal support bar 20. The anti-slip rubber block 21 ensures the tightness of the connection and ensures that the horizontal support bar 20 can provide stable support for the bottom of the horizontal hinged pedal 6, thereby strengthening the support strength of the horizontal hinged pedal 6 and making it easier for construction workers to stand on the horizontal hinged pedal 6 to carry out more stable construction work.

[0036] When construction workers need to place and retrieve tools during operations, hook blocks 14 are installed on the side of the top extension rod 4 at the top of the second vertical support rod 2, combined with the hanging blocks 16 on the side of the placement box 15. This makes it easier to hang the placement box 15, facilitating its retrieval and stable placement. At the same time, the internal partition 17 facilitates the division of the internal space, making it easier to place different types of construction tools and retrieve them. This also avoids the need for construction workers to frequently go up and down the platform to retrieve tools, thus improving the efficiency of construction work.
