[0031] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0033] This manual provides a temporary ladder for construction on floors. Figure 1 and Figure 2 As shown, it includes a first supporting mechanism 1 , a second supporting mechanism and a crossbeam 2 .

[0034] The second support mechanism is symmetrical to the first support mechanism; in this embodiment, the first support mechanism is used as an example. A plurality of crossbeams 2 are provided, which are arranged between the first support mechanism and the second support mechanism; specifically, between two columns.

[0035] The first support mechanism 1 includes a column 11, a first stabilizing device, a support arm 12, and a fixed plug rod 13. The first stabilizing device is arranged on the back of the column 11. The first stabilizing device includes a slider 14, which is a dovetail slider. The back of the column 11 is provided with a slide 15 slidably connected to the slider 14. The slide 15 is arranged along the height direction of the column. The top of the slide 15 is provided with a first through hole 16 that passes through both sides. The slide is provided with a second through hole 16 that passes through both sides near the bottom (not shown in the figure, the principle is the same as the first through hole). The slider 14 is rotatably connected to a hollow shaft 17, and the hollow shaft 17 is rotatably connected to a support rod 18. One end of the support arm 12 is rotatably connected to the bottom of the slide 15, and the other end is rotatably connected to the end of the support rod 18. The support arm 12, the support rod 18, and the column 11 can form a triangular structure. The fixed plug rod 13 can be inserted into the second through hole and the hollow shaft at the same time.

[0036] When using, please refer to Figure 4As shown, slide the slider downward so that the axis of the hollow shaft is aligned with the axis of the second through hole. At this time, the end of the support rod away from the slider extends outward, and at the same time, the end of the support arm connected to the support rod extends outward together to form a stable triangular structure. Then, insert the fixed rod 13 into the second through hole and the hollow shaft at the same time. Place the column support on the ground B, with the bottom edge of the triangular structure in contact with the ground B, and the back of the upper half of the column on the edge of the floor slab C. At this time, the force on the bottom of the column can be dispersed in two directions, improving the stability of the support. After use, pull out the fixed rod, move the slider back to the first through hole, and insert the fixed rod. At this time, the support rod and the arm are retracted.

[0037] In a preferred embodiment, please refer to Figure 2 As shown, a stopper protrusion 151 is provided within the slide groove 15. This stopper protrusion is located below the second through-hole and serves to limit the distance the slider can move, ensuring that the slider stops sliding after the hollow shaft in the slider aligns with the second through-hole. During use, the slider automatically slides down to the second through-hole by removing the fixing rod and then inserting the fixing rod for quick and convenient operation.

[0038] In a preferred embodiment, see Figure 3 As shown, a U-shaped groove is provided on the side of the slider 14 away from the chute 15, and the hollow shaft 17 is provided in the U-shaped groove, with both ends passing through the two sides of the U-shaped groove, providing installation space for the support rod to rotate and enabling the support rod to be accommodated in the chute.

[0039] In a preferred embodiment, see Figure 5 As shown, a second stabilizing device is provided near the top of the back of the column 11. The second stabilizing device includes a strip groove 31 provided on the back of the column 11. A supporting rod 32 is provided in the strip groove 31. One end of the supporting rod 32 is rotatably connected to the top of the strip groove 31, and the supporting rod can be rotated to a horizontal state. In a possible embodiment further described, a dovetail slider is provided at the end of the supporting rod 32, which is slidably connected to the strip groove through the dovetail slider. A number of locking bolt holes are provided on both sides of the column that penetrate into the strip groove. The supporting rod is rotatably connected to the dovetail slider through a limiting shaft. When in use, please refer to Figure 6 As shown, according to the usage, the supporting rod is rotated to a horizontal state, moved to the required height, and placed on the top surface of the floor slab to further increase the constraint points and improve the safety of use.

[0040] In a preferred implementation, Figure 7 As shown, the end of the crossbeam 2 is detachably connected to the column, a slot is provided on the side of the column 11, and a plug 21 is provided at the end of the crossbeam 2 to match the slot. After use, it can be further disassembled for easy transportation.

[0041] In a preferred implementation, Figure 8 As shown, the column can be folded. The column includes an upper half and a lower half, the upper half and the lower half are hinged, and the upper and lower positions of the hinge are respectively connected to ear plates 4, and the upper half and the lower half are fixed by bolts.

[0042] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0043] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
