However, the current staircase-type support frame has a large structure, cannot be disassembled, is inconvenient to transport, and has unsatisfactory use effect.

[0003] The Chinese patent with the authorization announcement number CN212671302U discloses an assembled staircase for small high-rise building construction, including a base plate and two inclined load-bearing beams, the bottom surface of the base plate is equipped with self-locking universal wheels, the upper surface of the base plate and the bottom surface of the load-bearing beam are evenly provided with corresponding plug-in sleeves, the upper and lower corresponding plug-in sleeves are used to detachably insert support columns for supporting the load-bearing beams, and a plurality of pedals are detachably clamped between the two load-bearing beams, and the pedals are evenly distributed along the length direction of the load-bearing beams. The above patent can be easily disassembled and assembled, so it is easy to transport.

[0004] However, in actual use of the above patent, when it is necessary to build a higher staircase, the length of the load-bearing beam and the support column at the end is relatively large, and it is difficult to shorten the length in order to ensure its structural strength, which leads to transportation difficulties and causes troubles in actual use.

[0005] Moreover, the angle between the pedal and the load-bearing beam of the above-mentioned patent is fixed and cannot be adjusted, and thus it is difficult to adjust the slope of the stairs according to the actual construction scene, causing inconvenience in use. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0022] refer to Figure 1-4 A prefabricated staircase for construction includes a tread 10. A plurality of treads 10 are stacked together to form a staircase. A group of columns 13 are symmetrically distributed and slidably connected on the straight parts of every two stacked treads 10. A connecting piece 21 is fixedly connected to the bottom of each column 13. A locking nut 14 is threadedly connected to the threaded area on each column 13.

[0023] The stairs are formed by fixing the modular pedals 10 and the columns 13 together. The pedals 10 and the columns 13 can be freely stacked to adjust the height of the stairs according to the actual usage scenario.

[0024] refer to Figure 4 Each pedal 10 has slide grooves 11 symmetrically distributed on both sides of the vertical portion, and a protrusion 12 is fixedly provided at the end of the straight portion of each pedal 10 at a position corresponding to the slide groove 11. The multiple pedals 10 are slidably connected to the protrusion 12 through the slide groove 11.

[0025] By providing the slide groove 11 and the protrusion 12, the stacking of the pedals 10 can be facilitated, and the fixed connection effect between two adjacent pedals 10 is increased during use, thereby ensuring the firmness of the stairs.

[0026] refer to Figure 4 A rotating seat 19 is fixedly connected to the top of each column 13, and an armrest 17 is rotatably connected to one side of each rotating seat 19. Two adjacent armrests 17 are slidably connected to each other. One end of each armrest 17 extending into another armrest 17 is fixedly connected to a bolt 20. A bolt groove 18 is opened on each armrest 17 at a position corresponding to the bolt 20, and each bolt 20 is slidably connected to the corresponding bolt groove 18.

[0027] By providing the handrail 17, protection can be provided for the workers, and the structural strength of the stairs can be further improved to ensure the firmness of the stairs during use.

[0028] refer to Figure 1 Two mounting plates 16 are symmetrically distributed and fixedly connected on both sides of the top of each pedal 10 .

[0029] By providing a plurality of mounting plates 16, it is more convenient to install the stairs on the building.

[0030] refer to Figure 1 , 4 A sleeve 15 is sleeved on the outer side of each column 13 between the stacked straight parts of the two pedals 10.

[0031] By installing sleeves 15 of different lengths, the height difference between the pedals 10 can be adjusted according to the actual construction scene, thereby adjusting the slope of the stairs.

[0032] In this embodiment, at the beginning, the operator can select a corresponding number of pedals 10 according to the required height during construction, and slide the plurality of pedals 10 together with the slide grooves 11 through the protrusions 12 to form a staircase prototype.

[0033] Then, screw the locking nut 14 onto each column 13, insert the corresponding column 13 into the part where the two pedals 10 overlap each other, fix the connecting piece 21 at the bottom of the column 13, and then screw the locking nut 14 to firmly fix the pedal 10 through the column 13.

[0034] And when the column 13 is inserted into the pedals 10 for connection, the sleeve 15 is sleeved on the column 13 and the sleeve 15 is located in the area where the two pedals 10 overlap each other, so that a height difference is generated between the two pedals 10. By selecting sleeves 15 of different lengths, the height difference between the pedals 10 can be controlled and adjusted to achieve the effect of adjusting the slope of the stairs.

[0035] Subsequently, a plurality of handrails 17 connected end to end are connected to the corresponding rotating seats 19, and bolts 20 are installed in the bolt grooves 18 to firmly fix two adjacent handrails 17, thereby forming a handrail that cooperates with the column 13 to provide protection for the workers and avoid danger to the workers.

[0036] Finally, the assembled staircase is hung or fixedly connected to the building wall through the hanging plate 16, so that workers can carry out construction at high places of the building.

[0037] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
