[0032] In related technologies, prefabricated stairs consist of step modules and edge beams, both made of concrete. Each step module comprises multiple individual steps, forming a single, integrated structure. The overall size and weight of the step module are significant, making assembly with the edge beams inconvenient. To address these issues, this application provides a stair assembly component, a prefabricated stair structure, and a prefabricated stair module, enabling easier assembly of steps and edge beams.

[0033] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0034] See Figure 1-2 The staircase assembly includes two side beams 1, an upper platform 2, a first connector 3, a lower platform 4, a second connector 5, multiple steps 6, and multiple third connectors 7. The two side beams 1 are spaced apart and arranged parallel to each other. The upper platform 2 is located above the lower platform 4, sandwiched between the two side beams 1. The first connector 3 is fixed to both the side beams 1 and the upper platform 2, securing them together. The lower platform 4 is sandwiched between the two side beams 1. The second connector 5 is fixed to both the side beams 1 and the lower platform 4, securing them together. The steps 6 are located between the upper platform 2 and the lower platform 4, with multiple steps 6 spaced along the length of the side beams 1, supporting them. The third connectors 7 are fixed to both the steps 6 and the side beams 1, securing them together. The upper surfaces of the lower platform 4, the steps 6, and the upper platform 2 are the surfaces for user walking.

[0035] See Figure 1-2 In the actual assembly process, the lower platform 4 is first assembled with the side beam 1 through the second connector 5, the upper platform 2 is assembled with the side beam 1 through the first connector 3, and the step 6 is assembled with the side beam 1 through the third connector 7. Then, concrete is poured at the junction of the lower platform 4 and the side beam 1, the junction of the upper platform 2 and the side beam 1, and the junction of the step 6 and the side beam 1, so that the side beam 1 is firmly fixed to the upper platform 2, the lower platform 4 and the step 6 respectively.

[0036] This application positions the two side beams 1 relative to each other by sandwiching the upper platform 2 and the lower platform 4 between the two side beams 1, without adjusting the gap between the two side beams 1, which facilitates the fixing of the steps 6 to the side beams 1; multiple steps 6 are installed on the side beams 1 by the third connector 7, without having to install all the steps 6 on the side beams 1 at once, which reduces the construction difficulty and makes the assembly of the stair assembly components more convenient.

[0037] See Figure 1 The side beam 1 includes an upper side beam 11, an inclined beam 12, and a lower side beam 13. The upper side beam 11 extends horizontally, and an upper platform 2 is sandwiched between two upper side beams 11. The upper side beam 11 is fixed to the upper platform 2, and its upper surface is flush with the upper surface of the upper platform 2. The inclined beam 12 is inclined relative to the horizontal direction along its length, and multiple steps 6 are spaced apart along the length of the inclined beam 12. The steps 6 are fixed to the inclined beam 12, and the inclined beam 12 supports the steps 6. The top end of the inclined beam 12 is connected to the upper side beam 11, and its bottom end is connected to the lower side beam 13. The lower side beam 13 extends horizontally, and a lower platform 4 is sandwiched between two lower side beams 13. The lower side beam 13 is fixed to the lower platform 4, and its upper surface is flush with the upper surface of the lower platform 4. When assembling the staircase components, after the upper side beam 11 is assembled with the upper platform 2 and the lower side beam 13 is assembled with the lower platform 4, the distance between the two inclined beams 12 remains unchanged. At this time, during the assembly of the steps 6 and the inclined beams 12, there is no need to adjust the distance between the two inclined beams 12. The steps 6 can be directly installed on the inclined beams 12, saving the installation time of the construction workers and improving the construction efficiency.

[0038] See Figure 1-5 The first connecting component 3 includes a first connecting frame 31, two first connecting bolts 32, and two first sleeves 33. The upper platform 2 has an upper connecting groove corresponding to the shape of the first connecting frame 31, and the first connecting frame 31 is embedded in the upper connecting groove. One of the first sleeves 33 is embedded in the upper platform 2, and the other first sleeve 33 is embedded in the upper side beam 11. When manufacturing the upper platform 2, the first sleeve 33 can be manufactured together with the upper platform 2 as a prefabricated component. When manufacturing the side beam 1, the first sleeve 33 can be manufactured together with the side beam 1 as a prefabricated component. The head of the first connecting bolt 32 is inserted into the first connecting frame 31, and the first connecting bolt 32 extends from the first connecting frame 31 into the first sleeve 33. The two first connecting bolts 32 are screwed onto the two first sleeves 33 respectively. After the upper platform 2 and the upper side beam 11 are fixed together by the first connector 3, concrete can be poured into the first connecting frame 31 to fill the first connecting frame 31, thereby strengthening the connection between the upper platform 2 and the upper side beam 11 and keeping the upper surface of the upper platform 2 flat.

[0039] See Figure 1The second connecting member 5 includes a second connecting frame, two second connecting bolts, and two second sleeves. The lower platform 4 has a lower connecting groove corresponding to the shape of the second connecting frame, and the second connecting frame is embedded in the lower connecting groove. One of the second sleeves is embedded in the lower platform 4, and the other second sleeve is embedded in the lower side beam 13. When manufacturing the lower platform 4, the second sleeve can be manufactured together with the lower platform 4 as a precast component. When manufacturing the side beam 1, the second sleeve can be manufactured together with the side beam 1 as a precast component. The head of the second connecting bolt is inserted into the second connecting frame, and the second connecting bolt extends from the second connecting frame into the second sleeve. The two second connecting bolts are screwed onto the two second sleeves respectively. After the lower platform 4 and the lower side beam 13 are fixed together by the second connecting member 5, concrete can be poured into the second connecting frame to fill it, thereby reinforcing the connection between the lower platform 4 and the lower side beam 13 and keeping the upper surface of the lower platform 4 flat.

[0040] See Figure 1-3 The third connector 7 includes an anchor portion 71 and a fixing portion 72, which are connected. The anchor portion 71 is embedded in the inclined beam 12, and the fixing portion 72 is fixed to the step 6. The anchor portion 71 bends horizontally from the bottom end of the fixing portion 72 and extends horizontally. During production, to facilitate the assembly of the staircase components, the third connector 7 and the side beam 1 together form a prefabricated component. When the inclined beam 12 is cast with concrete, the anchor portion 71 is embedded in the inclined beam 12, while the fixing portion 72 is exposed outside the inclined beam 12. The anchor portion 71 and the fixing portion 72 are made of metal and are integrally formed. By embedding the anchor portion 71 in the inclined beam 12, the installation process of the third connector 7 and the inclined beam 12 can be eliminated, and the fixing effect between the third connector 7 and the side beam 1 is ensured.

[0041] See Figure 1-3 In some embodiments, the top of the fixing part 72 is provided with an external thread, and the surface of the step 6 is provided with a relief groove 63. One end of the fixing part 72 extends into the relief groove 63. The third connecting member 7 also includes a fixing nut, which is screwed onto the fixing part 72 and is located in the relief groove 63. By cooperating with the fixing part 72, the step 6 can be easily assembled with the side beam 1, while the step 6 can be firmly fixed to the inclined beam 12. The top of the fixing part 72 is not higher than the upper surface of the step 6, and the top of the fixing nut is not higher than the upper surface of the step 6. After the stair assembly components are assembled, concrete can be poured into the relief groove 63 to fill it, thereby hiding the fixing part 72 and the fixing nut and reinforcing the fixing effect between the step 6 and the third connecting member 7, so that the upper surface of the step 6 remains flat.

[0042] See Figure 1-3In some embodiments, the stair assembly also includes a telescopic component 8. The top end of the telescopic component 8 is connected to the step 6, and the bottom end of the telescopic component 8 abuts against the inclined beam 12. The telescopic component 8 is located on the side of the third connecting member 7 near the lower platform 4. The telescopic component 8 is used to adjust the height of the side of the step 6 near the lower platform 4. Specifically, the telescopic component 8 includes a third sleeve 81 and an adjusting bolt 82. The third sleeve 81 is embedded in the bottom of the step 6, and the inner surface of the third sleeve 81 is provided with internal threads. The adjusting bolt 82 is threadedly connected to the third sleeve 81. When the step 6 is fixed to the inclined beam 12 through the third connecting member 7, the height of the side of the step 6 near the lower platform 4 can be finely adjusted by rotating the adjusting bolt 82, so that the upper surface of the step 6 is at a horizontal plane. The telescopic component 8 and the step 6 can be prefabricated together as precast components before assembling the stair assembly.

[0043] See Figure 1-3 Step 6 includes a tread 61 and two connecting parts 62. The tread 61 and connecting parts 62 are made of concrete. The two opposite ends of the tread 61 are connected to the two connecting parts 62 respectively. The tread 61 and the connecting parts 62 are integrally formed. The tread 61 is sandwiched between two side beams 1. A third sleeve 81 is embedded in the connecting part 62. A clearance groove 63 is located on the connecting part 62. The connecting part 62 is fixed to the third connecting piece 7. The side beams 1 support the connecting part 62, thereby supporting the entire step 6.

[0044] See Figure 1 and Figure 6The stair assembly also includes a fourth connector 9, which includes a first anchor 91, a second anchor 92, and a first connecting plate 93. The first anchor 91 and the second anchor 92 are arranged side by side. One end of the first anchor 91 is connected to the upper platform 2, and the other end of the first anchor 91 extends out of the upper platform 2. One end of the second anchor 92 is connected to the side beam 1, and the other end of the second anchor 92 extends out of the side beam 1. The first connecting plate 93 is fixed to the first anchor 91 and the second anchor 92 respectively. Specifically, the upper platform 2 is provided with a first upper clearance groove 21, and a first upper nut 211 is provided in the first upper clearance groove 21. The upper side beam 11 is provided with a second upper clearance groove 111, and a second upper nut 112 is provided in the second upper clearance groove 111. The first upper clearance groove 21 and the second upper clearance groove 111 are connected. The first connecting plate 93 is located in the first upper clearance groove 21 and the second upper clearance groove 111. One end of the first anchor 91 passes through the first connecting plate 93 and is screwed to the first upper nut 211. The first anchor 91 is fixed to the upper platform 2 by the first upper nut 211. One end of the second anchor 92 passes through the first connecting plate 93 and is screwed to the second upper nut 112. The second anchor 92 is fixed to the upper side beam 11 by the second upper nut 112. The side beam 1 and the upper platform 2 are fixed together by the first connecting plate 93, the first anchor 91 and the second anchor 92 respectively. After the stair assembly components are assembled, concrete can be poured into the first upper clearance groove 21 and the second upper clearance groove 111 to fill them, thereby reinforcing the fixation of the upper side beam 11 and the upper platform 2 and keeping the upper surface of the upper platform 2 flat. The portions of the first anchor 91 and the second anchor 92 extending beyond the upper platform 2 can be embedded in the external concrete structure, which can be a beam 200, a cavity, a column, etc., thus fixing the stair assembly components to the external concrete structure.

[0045] See Figure 1-4The stair assembly also includes a fifth connector 10, which includes a third anchor 101, a fourth anchor 102, and a second connecting plate 103. The third anchor 101 and the fourth anchor 102 are arranged side by side. One end of the third anchor 101 is connected to the lower platform 4, and the other end of the third anchor 101 extends out of the lower platform 4. One end of the fourth anchor 102 is connected to the side beam 1, and the other end of the fourth anchor 102 extends out of the side beam 1. The second connecting plate 103 is fixed to the third anchor 101 and the fourth anchor 102 respectively. Specifically, the lower platform 4 has a first lower clearance groove, and a first lower nut is provided in the first lower clearance groove. The lower side beam 13 has a second lower clearance groove, and a second lower nut is provided in the second lower clearance groove. The first lower clearance groove and the second lower clearance groove are connected. The second connecting plate 103 is located in the first lower clearance groove and the second lower clearance groove. One end of the third anchor 101 passes through the second connecting plate 103, and the third anchor 101 is screwed to the first lower nut. The third anchor 101 is fixed to the lower platform 4 through the first lower nut. One end of the fourth anchor 102 passes through the second connecting plate 103, and the fourth anchor 102 is screwed to the second lower nut. The fourth anchor 102 is fixed to the lower side beam 13 through the second lower nut. The side beam 1 and the lower platform 4 are fixed together by the second connecting plate 103, the third anchor 101, and the fourth anchor 102. After the stair assembly components are assembled, concrete can be poured into the first and second lower clearance slots to fill them, thereby reinforcing the lower side beam 13 and the lower platform 4 and ensuring the upper surface of the lower platform 4 remains flat. The portions of the third anchor 101 and the fourth anchor 102 extending beyond the upper platform 2 can be embedded in the external concrete structure, which can be a beam 200, a cavity, a column, etc., thus fixing the stair assembly components to the external concrete structure.

[0046] See Figure 1 In some embodiments, the upper platform 2 is provided with a step 22 on the side facing the lower platform 4. The structure of the step 22 is the same as that of the step 6. The step 22 is fixed to the side beam 1 by a third connector 7.

[0047] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a prefabricated staircase structure and corresponding embodiments.

[0048] See Figure 1 and Figure 7The prefabricated staircase structure includes a connecting unit 100 and a staircase assembly. The connecting unit 100 includes two beams 110, a sixth connector, and multiple treads 120. The two beams 110 are arranged in parallel, with their length direction inclined relative to the horizontal direction. The multiple treads 120 are spaced apart along the length direction of the beams 110, supporting the treads 120. The structure of the treads 120 is the same as that of the steps 6, and the treads 120 can be fixed to the beams 110 with screws.

[0049] See Figure 1 and Figure 7 In the actual assembly process, the number of connecting units 100 and stair assembly components can be adjusted according to the number of floors. When assembling a multi-story staircase, the connecting units 100 and stair assembly components are arranged alternately, with the bottommost component being a stair assembly component. Taking a combination of two stair assembly components and one connecting unit 100 as an example, the bottom end of the beam 110 is fixed to the upper platform 2 of the lower stair assembly component via a sixth connector, and the top end of the beam 110 is fixed to the lower platform 4 of the upper stair assembly component via a sixth connector. Taking a combination of one stair assembly component and one connecting unit 100 as an example, the bottom end of the beam 110 is fixed to the upper platform 2 of the stair assembly component via a sixth connector. This design facilitates the construction of multi-story staircases and makes the installation of steps 6 and treads 120 more convenient, improving construction efficiency.

[0050] See Figure 1 and Figure 7 The prefabricated staircase structure also includes a crossbeam 200, which is fixed to the upper platform 2 and supports the upper platform 2. The crossbeam 200 is located on the side of the upper platform 2 opposite to the side beam 1. The crossbeam 200 can be a crossbeam 200 between external floor units. When assembling a multi-story staircase, taking the combination of two staircase assembly components and a connecting unit 100 as an example, the upper platform 2 of the lower staircase assembly component and the upper side beam 11 are fixed to the crossbeam 200 by means of a first anchor 91 and a second anchor 92. The lower platform 4 of the upper staircase assembly component and the lower side beam 13 are fixed to the crossbeam 200 by means of a third anchor 101 and a fourth anchor 102.

[0051] See Figure 1 , Figure 4 , Figure 6 and Figure 7In the actual assembly process, the first anchor 91 and the second anchor 92 can be cast into the corresponding crossbeam 200 first, the third anchor 101 and the fourth anchor 102 can be cast into the corresponding crossbeam 200 first, the lower platform 4 can be connected to the third anchor 101 so that the third anchor 101 extends into the first lower clearance groove, the side beam 1 can be connected to the fourth anchor 102 and the second anchor 92 respectively, the upper platform 2 can be connected to the first anchor 91 so that the first anchor 91 extends into the first upper clearance groove 21, the first connecting plate 93 can be fixed to the first anchor 91 and the second anchor 92 respectively, and the second connecting plate 103 can be fixed to the third anchor 101 and the fourth anchor 102 respectively, thereby completing the assembly of the side beam 1, the upper platform 2 and the lower platform 4 with the crossbeam 200.

[0052] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a prefabricated staircase module and corresponding embodiments.

[0053] See Figure 1 and Figure 8 The prefabricated stair module includes a crossbeam 200 and at least two stair assembly components. These at least two stair assembly components are staggered along the height direction, and adjacent stair assembly components are fixed together by the crossbeam 200. In two adjacent stair assembly components, the lower platform 4 of the upper stair assembly component is attached to and side-by-side with the upper platform 2 of the lower stair assembly component, and they are at the same height.
