[0002] The prefabricated building stairwell operating platform is a new technology applicable to the field of construction engineering technology. Due to the characteristics of the construction process of prefabricated residential buildings, the installation of prefabricated stairs in the stairwell lags behind the structural construction layer. For double-run stairwells, after the template is installed, the template of the prefabricated stair rest platform of the first run on the same floor of the stairwell is one floor high, and the template of the prefabricated stair rest platform of the second run on the same floor is two floors high. This structural situation not only makes it impossible for practitioners to go up and down the top plate template surface of the stairwell, but also poses a safety hazard of falling when moving along the edge. In addition, in order to solve the problem of safe construction of shear walls and rest platforms in each stairwell, the temporary operating platform on each floor makes the existing operating platform unrecyclable, which seriously wastes manpower and material resources and has poor economic efficiency.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0035] like Figure 1-Figure 7 As shown, a steel ladder platform in a building stairwell provided by an embodiment of the utility model comprises two vertically arranged lower platform columns 11 and two vertically arranged upper platform columns 12, one side of the lower platform column 11 and the upper platform column 12 are detachably connected to a first diagonal rod 21, and the other side of the lower platform column 11 and the upper platform column 12 are detachably connected to a second diagonal rod 22;

The step side beam 23, the protection rod 24 and the handrail rod 25 are parallel to the first oblique rod 21 and arranged from bottom to top, with a vertical spacing of 600mm between adjacent verticals. The two ends of the step side beam 23 are punched and coaxial with the circular punching holes on the lower platform column 11 and the upper platform column 12 that are closest to the height of the stair rest platform 92 and the rest platform 93 template.

[0037] The number of the first oblique rod 21, the second oblique rod 22, the step side beam 23, the protection rod 24 and the handrail rod 25 are all two, and the side surfaces of the two step side beams 23 close to each other are jointly provided with a step structure 5;

[0038] The outer side of the handrail rod 25 is detachably connected to a support column 61, and the tops of the sides where the two support columns 61 are close to each other, the tops and bottoms of the sides where the two lower platform columns 11 are close to each other, and the bottoms of the sides where the two upper platform columns 12 are close to each other are all detachably connected to a first reinforcement component 3, and the surface of the first reinforcement component 3 located at the top of the lower platform column 11, the surface of the first reinforcement component 3 located at the top of the support column 61, and the tops of the sides of the support column 61 and the lower platform column 11 are all detachably connected to a platform rod 62.

[0039] The lower platform column 11, the upper platform column 12, the first diagonal bar 21, the second diagonal bar 22, the step side beam 23, the protective bar 24, the handrail bar 25, the support column 61 and the platform rod 62 are all steel components, and the surfaces of the lower platform column 11, the upper platform column 12, the first diagonal bar 21, the second diagonal bar 22, the step side beam 23, the protective bar 24, the handrail bar 25, the support column 61 and the platform rod 62 are all provided with a plurality of circular punching holes, and the diameter of the circular punching holes provided on the lower platform column 11, the upper platform column 12, the first diagonal bar 21, the second diagonal bar 22, the step side beam 23, the protective bar 24, the handrail bar 25, the support column 61 and the platform rod 62 is 18 mm, and the axis spacing between two adjacent circular punching holes is 100 mm;

[0040] The two farthest circular punching holes on the surface of the first inclined rod 21 are coaxially connected to the third circular punching holes on the surface of the lower platform column 11 and the upper platform column 12 from low to high, respectively; the two farthest circular punching holes on the surface of the second inclined rod 22 are coaxially connected to the third circular punching hole on the surface of the upper platform column 12 from low to high and a circular punching hole in the middle area of ​​the surface of the lower platform column 11;

[0041] After the first diagonal rod 21 and the second diagonal rod 22 are fixed on the lower platform column 11 and the upper platform column 12, an isosceles triangle structure is formed among the second diagonal rod 22, the first diagonal rod 21 and the lower platform column 11, that is, the punching holes of the first diagonal rod 21 and the second diagonal rod 22 located at one end of the stair rest platform 91 are coaxially bolted to the third punching hole on the surface of the upper platform column 12 from low to high, and on both sides of the upper platform column 12.

[0042] In one embodiment of the utility model, the steel ladder platform is mainly suitable for the construction platform of the stairwell of residential and apartment prefabricated buildings with a floor height of 2900mm to 3000mm, and the application environment of the steel ladder platform is as follows: Figure 7 As shown, the steel ladder platform is placed on the first prefabricated staircase 101 and the second prefabricated staircase 102, and the two sides of the entire steel ladder platform correspond to the first resting platform 91, the third resting platform 93, the second resting platform 92, and the fourth resting platform 94 respectively;

[0043] By setting a plurality of platform rods 62 on the support column 61 and the first reinforcement assembly 3, horizontal protection of the staircase plane opening can be formed. In addition, the vertical distance between the top surface of one end of the platform rod 62 facing the upper platform column 12 and the step structure 5 directly below it is less than 1.8 meters, in order to reduce the height of the platform formed by the platform rods 62 above the ground;

[0044] It can be understood that the coaxial connection method mentioned in the above scheme refers to aligning the designated circular holes on the two components, passing a bolt that matches the diameter of the circular hole through the circular hole, and then putting a fastening nut on the bolt and tightening it, so as to firmly connect the two components together in a coaxial connection manner.

[0045] Under the premise of using several square tubes with a diameter of 18mm and a hole spacing of 100mm to develop and construct the steel ladder platform, technical personnel in this field have found through continuous size adjustment and optimization that the bolt holes of each rod at the connection are completely coaxial and can also match the size and height difference of the stairwell, thereby achieving precise docking of the structure and overall functionality. If any of the conditions of the coaxiality of the bolt holes, the size and height difference of the stairwell are not met, the designed steel ladder platform cannot be successfully constructed. This method ensures the structural integrity and stability of the platform. In addition, the use of bolt connection to assemble each rod also improves the convenience of the overall construction of the steel ladder platform.

[0046] In this embodiment, the first reinforcement assembly 3 is composed of a first horizontal rod 31 and two first vertical rods 32 , and the two first vertical rods 32 are fixedly connected to the two ends of the first horizontal rod 31 , respectively.

[0050] It can be understood that by arranging the first reinforcement component 3 and the second reinforcement component 4 on the lower platform column 11 and the upper platform column 12 , the lateral stiffness of the lower platform column 11 and the upper platform column 12 can be enhanced.

[0051] In this embodiment, the step structure 5 is composed of a plurality of steel step assemblies 51 and a tail steel step assembly 52. ​​The steel step assembly 51 is composed of a first platform plate 511, a skirting plate 512 and a first buckle plate 513.

The first platform plate 511 is fixedly connected to the step side beam 23.

[0052] The tail end steel step assembly 52 is composed of a second platform plate 521 and a second buckle plate 522, and the second buckle plate 522 is fixedly connected to the side of the second platform plate 521, the second platform plate 521 is fixedly connected to the step side beam 23, the first buckle plate 513 on the first platform plate 511 located at a high place is buckled on the skirting plate 512 of the first platform plate 511 located at a low place, and the second buckle plate 522 on the second platform plate 521 is buckled on the skirting plate 512 of the first platform plate 511 located at the highest place.

In addition, the steel step 51 and the tail steel step 52 are welded to the step side beam 23 to enhance the planar rigidity of the body.

[0054] In this embodiment, the top areas outside the lower platform columns 11 and the upper platform columns 12 are both provided with lifting rings 7 , and the bottom ends of the lower platform columns 11 and the upper platform columns 12 are both welded with pads 8 .

[0055] like Figure 8As shown, in another embodiment of the present invention, the second oblique rod 22 is synchronously lifted to an appropriate height so that the second oblique rod 22 and the protective rod 24 are coaxially bolted together on the first column 11;

[0056] In this embodiment, the lower platform column 11, the upper platform column 12, the first diagonal rod 21, the second diagonal rod 22 and the protective rod 24 together form a stable side elevation truss on one side of the body;

[0057] In this embodiment, the first oblique rod 21, the second oblique rod 22 and the two ends of the protective rod 24 are coaxially bolted to the lower platform column 11 and the upper platform column 12 respectively;
