Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 As shown, a prefabricated staircase with high strength includes a step 1, a stair inclined platform 4, a stair handrail 5, a support frame 6, and a stair landing 7. It also includes an auxiliary installation component 2 and a fixing component 3. The stair inclined platform 4 is installed on both sides of the step 1, the stair handrail 5 is fixedly installed on the outer surface of the stair inclined platform 4, the stair landing 7 is installed on the upper part of the support frame 6, the auxiliary installation component 2 is installed on the side wall of the stair inclined platform 4, and the fixing component 3 is installed on the outer surface of the support frame 6. The provided auxiliary installation component 2 can achieve convenient installation, making the overall construction efficiency faster.

[0027] As Figures 2-4As shown, the auxiliary installation component 2 includes a mounting plate 201 fixedly installed on the inner side wall of the stair landing 4. One end of the mounting plate 201 facing the step 1 is provided with a mounting groove, and both sides of the step 1 are inserted into the interior of the mounting groove. A slot 202 is provided between the inner and outer walls of the step 1. A circular groove 203 is provided on the side of the mounting plate 201. A rod body 204 is fixedly installed at the lower part of the mounting plate 201. A pull plate 205 slides on the rod body 204. A spring 206 is fixedly connected between the outer surface of the pull plate 205 and the lower part of the mounting plate 201. A plug rod 207 slides between the inner and outer walls of the mounting plate 201, and the plug rod 207 is inserted into the interior of the slot 202. The auxiliary installation component 2 further includes a mounting rod 208. One end of the mounting rod 208 penetrates between the inner and outer walls of the mounting plate 201. The mounting rod 208 is located inside the circular groove 203. A thread is provided at the end of the mounting rod 208 penetrating the mounting plate 201, and a nut 209 is screwed on the outer surface of the thread. One end of the upper part of the stair landing 4 is fixedly installed with a connecting plate body 210. An installation notch 211 is provided inside the stair platform 7. A connecting rod body 212 slides inside the installation notch 211. The lower part of the connecting plate body 210 is fixedly connected to the top of the connecting rod body 212. When the user is building, the support frame 6 is fixed on the ground. When the stair platform 7 is built on top of the support frame 6 and the top is completed, the connecting plug plate 302 is inserted into the square slot 303 to complete the initial fixation. When the connecting plug plate 302 is inserted into the square slot 303, the connecting plate body 210 and the connecting rod body 212 are simultaneously limited, and then one side of the stair landing 4 is built. After the initial fixation is completed, the bolt 305 is inserted into the circular through groove 304, and finally the anti-slip nut 306 is tightened to complete the fixation of the bottom of the device body. After the base is built, the connecting plate body 210 is aligned. After one side of the bottom is built, the step 1 is inserted into the mounting plate 201. At this time, when the plug rod 207 touches the slot 202, it will be inserted into its interior to complete the initial fixation. Then the mounting rod 208 is inserted into the circular groove 203, and finally the nut 209 is tightened to complete the secondary fixation. By disassembling and assembling, the floor area occupied by the stairs during transportation is reduced, which is convenient for transportation. At the same time, after the user has completed the construction, they can choose to weld or not weld according to the construction needs. When temporary construction is required, it is not necessary to weld, making the whole more flexible in use. Thus, it avoids problems such as the large floor area occupied by the welded stairs and difficulty in transportation caused by transporting them to the construction site by means of in-factory welding and centralized hauling.

[0028] As Figures 5-6As shown in the figure, the fixing component 3 includes a mounting block 301 that slides on the top of the support frame 6. The top of the mounting block 301 passes through the mounting notch 211 and is fixedly connected to the lower part of the connecting rod body 212. A connecting plug board 302 is arranged on the outer surface of the support frame 6. A square slot 303 is opened between the inside of the support frame 6 and the mounting block 301. One end of the connecting plug board 302 is inserted into the inside of the square slot 303. Circular through slots 304 are horizontally penetrated between the connecting plug board 302 and the inner and outer walls of the mounting block 301 and the support frame 6. Bolts 305 are arranged inside the circular through slots 304. Anti-slip nuts 306 are screwed on the outer surfaces of the bolts 305. The initial fixation is completed by inserting the connecting plug board 302 into the square slot 303. When the connecting plug board 302 is inserted into the square slot 303, the connecting plate body 210 and the connecting rod body 212 are simultaneously limited, and then the unilateral construction of the staircase inclined platform 4 is completed. After the initial fixation is completed, the bolts 305 are inserted into the circular through slots 304, and finally the anti-slip nuts 306 are tightened to complete the fixation of the bottom of the device body. By segmental construction, the overall installation efficiency is higher and more flexible and changeable.

[0029] When the present utility model is in use, after the user conducts on-site measurement, the staircase parts are transported to the construction site. By building the staircase platform 7 on the top of the support frame 6, when the top construction is completed, the connecting plug board 302 is inserted into the square slot 303 to complete the initial fixation. When the connecting plug board 302 is inserted into the square slot 303, the connecting plate body 210 and the connecting rod body 212 are simultaneously limited, and then the unilateral construction of the staircase inclined platform 4 is completed. After the initial fixation is completed, the bolts 305 are inserted into the circular through slots 304, and finally the anti-slip nuts 306 are tightened to complete the fixation of the bottom of the device body. After the base is built, the connecting plate bodies 210 are aligned. When the unilateral construction of the bottom is completed, the steps 1 are inserted into the mounting plate 201. At this time, when the insertion rod 207 touches the slot 202, it will be inserted into its inside to complete the initial fixation. Then the mounting rod 208 is inserted into the inside of the circular slot 203, and finally the nut 209 is tightened to complete the secondary fixation. By disassembly and assembly, the staircase occupies less area during transportation, which is convenient for transportation. At the same time, after the user completes the construction, they can choose to weld or not weld according to the construction needs. When temporary construction is required, it is not necessary to weld, making the whole more flexible in use. Thereby, it avoids problems such as the large floor area of the welded staircase and inconvenient transportation caused by transporting it to the construction site by means of in-factory welding and centralized hauling.
