[0001] The present invention belongs to the technical field of construction engineering construction, and particularly relates to an operation platform for a prefabricated building staircase and a construction method therefor. Background Art

[0002] At present, in the field of construction engineering construction, the prefabricated staircase assembly method is usually adopted to improve the construction progress. For prefabricated buildings with prefabricated staircases, since it is difficult to synchronize the hoisting of prefabricated staircases with the floor structure surface, there are the following two problems: First, there is no operating surface for the staircase template, and the formwork cannot be erected. Second, before the installation of the prefabricated staircase, this is a temporary edge opening, posing a relatively large safety hazard. Therefore, edge protection must be installed here. However, this part of the protection must be removed before the installation of the prefabricated staircase. Therefore, the construction steps are cumbersome, and the protection and construction costs are relatively high. Summary of the Invention

[0003] The purpose of the present invention is to provide an operation platform for a prefabricated building staircase, aiming to solve the technical problems that there is no operating surface for the staircase template before the assembly of prefabricated staircases in existing prefabricated buildings and the safety protection method is cumbersome.

[0004] The present invention is realized as follows. An operation platform for a prefabricated building staircase for the construction of a scissors staircase includes two operation frames. Each operation frame includes a top plate and a bottom plate connected to each other, and at least one partition plate located between the top plate and the bottom plate. The partition plate divides the space between the top plate and the bottom plate into multiple operation spaces, and an operation opening for construction workers to construct is provided at the edge of the operation space.

[0010] In one embodiment, each of the operation frames further includes a backing plate structure, and the backing plate is disposed on one side of the bottom surface of the bottom plate and protrudes beyond the edge of the bottom plate.

[0011] Another object of the present invention is to provide a construction method for a prefabricated building staircase, including:

[0012] Step S1: Hoist and place the prefabricated building staircase operation platform described in the above embodiments in the scissor staircase;

[0013] Step S2: Erect the staircase formwork around the two operation frames, and after pouring the concrete, disassemble the staircase formwork;

[0014] Step S3: Lift and remove the prefabricated building staircase operation platform from the scissor staircase, and hoist and install the precast staircase in the scissor staircase.

[0015] In one embodiment, the height of the operation frame is two storeys high, and the staircase formwork of two storeys high is erected around the two operation frames.

[0016] In one embodiment, the construction method for the prefabricated building staircase further includes: installing the backing plate structure on one side of the bottom surface of the bottom plate, placing the backing plate structure on the cross beam of the scissor staircase, and placing the other side of the bottom surface of the bottom plate on the upper end of the precast staircase; repeating steps S1 to S3.

[0034] In order to illustrate the technical solutions described in the present invention, the following will be described in detail with reference to specific drawings and embodiments.

[0035] Please refer to Figure 1 and Figure 2 , the embodiments of the present invention first provide an assembled building staircase operation platform, which is used for the construction of the scissors staircase 9. Please refer to Figure 8 specifically. The assembled building staircase operation platform includes two operation frames 1. Each operation frame 1 includes a top plate 12 and a bottom plate 11 that are connected to each other, and at least one partition plate 13 located between the top plate 12 and the bottom plate 11. The partition plate 13 divides the space between the top plate 12 and the bottom plate 11 into multiple operation spaces 10. The edges of the operation spaces 10 are not completely enclosed, but are provided with operation openings for construction workers to construct. Construction tools can be placed on the bottom plate 11 and the partition plate 13. Construction workers are located in each operation space 10 and stand at the edges of the bottom plate 11 and the partition plate 13, and construct through the operation openings, such as erecting the staircase formwork and removing the staircase formwork after pouring concrete.

[0036] The prefabricated building staircase operation platform provided by the embodiment of the present invention includes two operation frames 1. Each operation frame 1 includes a top plate 12 and a bottom plate 11 that are connected to each other, and at least one partition plate 13 located between the top plate 12 and the bottom plate 11. The partition plate 13 divides the space between the top plate 12 and the bottom plate 11 into multiple operation spaces 10. Operation openings for construction workers to construct are provided at the edges of the operation spaces 10. In this way, the construction workers can perform the construction operation of erecting the staircase formwork for the scissors staircase 9 through the operation openings of the two operation frames 1. Moreover, the division of the multiple operation spaces 10 is more conducive to construction. In addition, the two operation frames 1 respectively enclose the edge openings of the two side floor areas, which can prevent construction workers and construction tools from falling, reduce the safety protection construction of the edge openings, reduce the protection steps and lower the protection cost. In addition, the top plate 12 also protects the construction workers from being injured by falling objects from above.

[0037] The scissors staircase 9 is divided into two parts. One operation frame 1 is placed into each part by hoisting, and the construction workers construct from the periphery of each operation frame 1 to erect the formwork of the scissors staircase 9.

[0038] The top plate 12, the bottom plate 11 and the partition plate 13 are all rectangular, and the operation frame 1 is arranged in a cuboid shape, as Figures 1 to 4 shown.

[0039] Please refer to Figure 2 and Figure 3 , the top plate 12, the bottom plate 11 and the partition plate 13 all include steel bar mesh, and may also include cross bars (not shown) connected to the four sides of the steel bar mesh. In this way, the top plate 12, the bottom plate 11 and the partition plate 13 can have better load-bearing capacity to support the weight of the operators.

[0040] The height of the operation frame 1, that is, the distance between the top plate 12 and the bottom plate 11, can be considered based on construction needs and protection needs.

[0041] In one embodiment, the distance between the bottom plate 11 and the top plate 12 is equal to one floor height. The advantage of this is that it can protect both sides of the staircase opening of the current floor under construction, and the construction workers can erect the staircase formwork of one floor height at a time.

[0042] In another embodiment, the distance between the bottom plate 11 and the top plate 12 is greater than one floor height. The advantage of this is that it can also at least partially enclose both sides of the staircase opening of the upper floor, and the construction workers can erect the staircase formwork of more than one floor height at a time.

[0043] Optionally, the distance between the bottom plate 11 and the top plate 12 is two storey heights. The advantage of this is that the topmost top plate 12 can be flush with the openings on both sides of the third floor staircase. In this way, in fact, a protection for the third floor is also formed. Moreover, the operator can set up the formwork for the staircase of two storey heights at one time, significantly reducing the number of hoistings and protective measures and lowering the construction cost.

[0044] In each operation rack 1, the number of partition plates 13 is set according to the height of the operation rack 1, so that the height of each operation space 10 can be adapted to the height of the construction workers and is convenient for construction.

[0045] For example, the current storey height requirement for civil buildings is more than 2.8 meters, specifically such as 2.8 meters to 3.2 meters. For two storey heights of 5.6 meters to 6.4 meters, then, in each operation rack 1, three partition plates 13 can be provided to divide into four operation spaces 10, and the height of each operation space 10 is 1.4 meters to 1.6 meters. Or two partition plates 13 can be provided to divide into three operation spaces 10, and the height of each operation space 10 is 1.87 meters to 2.13 meters.

[0046] In an alternative embodiment, the height of each operation rack 10 is 5.6 meters. Further, the length of each operation rack is 1.32 meters and the width is 1 meter. Of course, according to the different sizes of the scissor staircase 9, the operation rack 10 can have other numerical sizes.

[0047] In other alternative embodiments, according to the different heights of the operation rack 1, other numbers of partition plates 13 are allowed.

[0048] Please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 , in one embodiment, a ladder opening 130 is formed on each partition plate 13, and each operation rack 1 further includes a ladder 15 provided from the bottom plate 11 to each ladder opening 130. The advantage of this is that the operator can switch between different operation spaces 10 by means of the ladder 15 and the ladder opening 130, which is convenient for construction.

[0049] The size of the ladder opening 130 should be convenient for construction workers to pass through. Specifically, the length of the ladder opening 130 can be 700 mm and the width can be 700 mm.

[0050] Specifically, please refer to Figure 3 , in one embodiment, the ladder opening 130 is formed in the middle of the rectangular partition plate 13. The advantage of this is that the ladder opening 130 has a certain distance from the four peripheral edges of the partition plate 13. Especially for the long side edges of the partition plate 13, this section of space can be used for the operator to stand and construct.

[0051] The ladder openings 130 on each partition board 13 can be aligned with each other, as Figure 5 and Figure 6 shown. The advantage of this is that the ladder 15 can extend continuously. Of course, in other embodiments, according to other construction requirements, the ladder openings 130 on each partition board 13 can be arranged in a staggered manner.

[0052] In a specific application, the width of the ladder 15 can be 700 mm, and the step spacing of the ladder 15 can be 400 mm. In other alternative embodiments, according to the different sizes of the operating frame 1, the ladder 15 can also have other sizes.

[0053] Please refer to Figure 5 and Figure 6 , in one embodiment, each operating frame 1 further includes at least one cover plate 17. The cover plate 17 is arranged at the ladder opening 130 and is hinged to the partition board 13. The cover plate 17 is arranged to flip upwards. The advantage of this is that when the construction workers in an operating space 10 need to switch to another operating space 10 by the ladder 15, the cover plate 17 can be opened; when the ladder 15 is not temporarily needed, the cover plate 17 can be flipped to close the ladder opening 130, so as to prevent construction workers or construction tools from falling, and also avoid physical injury to the construction workers on the lower layer.

[0054] The size of the cover plate 17 can correspond to the size of the ladder opening 130, which will not be elaborated here.

[0055] Please refer to Figure 1 , Figure 5 and Figure 6 , in one embodiment, each operating frame 1 further includes a plurality of vertical rods 14. The plurality of vertical rods 14 are vertically connected between the edges of the top plate 12 and the bottom plate 11. Specifically, the plurality of vertical rods 14 are connected between the cross bars of the top plate 12, the bottom plate 11 and the partition board 13 by welding or other means to ensure the strength of the operating frame 1. The plurality of vertical rods 14 are arranged at intervals, and the operating openings as mentioned above are formed between the vertical rods 14. In a specific application, the vertical rods 14 can be steel square tubes of 200 mm × 200 mm.

[0056] Further, please refer to Figure 3 and Figure 7 , in one embodiment, each operating frame 1 further includes a plurality of flap plates 18. The flap plates 18 are hinged to the edges of the bottom plate 11 and the partition board 13, and the flap plates 18 are arranged to be able to flip towards the inside of the operating space 10. The flap plates 18 are used to abut against the surface of the formwork of the stairwell that has been erected after flipping ( Figure 3The frame indicated by the dashed line in the middle represents the surface of the formwork already erected in the scissor staircase 9). The advantage of this is that by flipping the flap 18, the space between the edges of the bottom plate 11 and the partition plate 13 and the formwork can be temporarily closed. Furthermore, it can prevent construction workers or construction tools from falling through this space, further ensuring the personal safety of construction workers.

[0057] In a specific application, at least one flap 18 can be provided on the long sides, short sides of the bottom plate 11, and the long sides and short sides of the partition plate 13. The size of the flap 18 is set according to needs. For example, the length of the flap 18 can be 500 mm and the width can be 300 mm. In other alternative embodiments, according to the different sizes of the operating frame 1 and the scissor staircase 9, the flap 18 can have other size ranges.

[0058] After the use of the operating platform of the prefabricated building staircase is completed and it needs to be lifted out of the scissor staircase 9, the flap 18 can be flipped upward into the operating space 10. Specifically, when setting the flap 18, it is necessary to avoid the vertical pole 14 to prevent the obstruction of the vertical pole 14. The flap 18 can be connected to the bottom plate 11 and the partition plate 13 by hinges (not shown).

[0059] In one embodiment, each operating frame 1 further includes a cushion structure 16. The cushion structure 16 is provided on the bottom surface of the bottom plate 11 and protrudes from the edge of the bottom plate 11, and the cushion structure 16 is arranged corresponding to the position of the cross beam 91 of the scissor staircase 9, that is, the cushion structure 16 is located on the bottom surface of the bottom plate 11 corresponding to the cross beam 91 of the scissor staircase 9, as Figure 5 and Figure 6 shown. The setting of this cushion structure 16 is considered for two reasons. First, in order for the operating frame 1 to enter the scissor staircase 9, the length and width of the operating frame 1 should be less than the horizontal distance between the two cross beams 91 and the horizontal width of the cross beam 91 in the scissor staircase 9. Therefore, when the operating frame 1 is placed in the scissor staircase 9, it needs assistance in the length direction to be erected on the cross beam 91. Second, when at least one layer of precast staircase 8 is lifted into the scissor staircase 9, the upper end of the precast staircase 8 is erected on one side of the cross beam 91, resulting in a higher height on this side and a lower height on the other side. Please refer to Figure 8 . At this time, the cushion structure 16 can lengthen the bottom plate 11, so that it can be erected on the cross beam 91. Furthermore, the cushion structure 16 also raises the bottom plate 11, enabling the operating frame 1 to be horizontally arranged for easy construction, as Figure 8 shown.

[0060] Optionally, the connection between the backing plate structure 16 and the bottom plate 11 is detachable. The advantage of this is that when constructing the staircase formwork for the first floor, the backing plate structure 16 can be disassembled, and when constructing the staircase formwork for other floors, the backing plate structure 16 can be installed. In this way, the operating frame 1 can be recycled, and when it is necessary to temporarily store the operating frame 1, it is also beneficial for it to be placed horizontally.

[0061] It should be noted that after the backing plate structure 16 is installed on the bottom surface of the bottom plate 11, the total length of the backing plate structure 16 and the bottom plate 11 is greater than the distance between the two cross beams 91. When lifting the operating frame 1 away from the scissor staircase 9, it is necessary to manually assist in tilting the operating frame 1 so that the backing plate structure 16 can be smoothly removed. This can be operated in actual construction and will not be elaborated here.

[0062] The backing plate structure 16 may include one backing plate 160 or may include a plurality of spaced-apart backing plates 160. The specific form of the backing plate 160 is not limited, such as Figure 6 shown. And the height of the backing plate 160 is set according to the height relationship between the precast staircase 8 and the cross beam 91, and there is no special limitation on this.

[0063] Please refer to Figure 1 、 Figure 5 and Figure 6 , in an embodiment, each operating frame 1 further includes at least one lifting hook 19, and the lifting hook 19 is provided on the outer surface of the top plate 12. The lifting hook 19 is used to connect with a lifting device to lift the operating frame 1. The form, position, and number of the lifting hook 19 are not particularly limited, as long as it can ensure lifting balance and stable connection.

[0064] Please refer to Figure 9 , and in combination with the above Figures 1 to 8 , the embodiment of the present invention further provides a construction method for an assembled building staircase, which is implemented by means of the assembled building staircase operating platform described in the above embodiments. Specifically, the construction method for the assembled building staircase includes:

[0065] Step S1, hoist and place the assembled building staircase operating platform described in the above embodiments into the scissor staircase 9;

[0066] Step S2, erect the staircase formwork around the four sides of the two operating frames 1, and after pouring the concrete, disassemble the staircase formwork to obtain the staircase wall surface;

[0067] Step S3, hoist and remove the assembled building staircase operating platform from the scissor staircase 9, and hoist and install the precast staircase 8 into the scissor staircase 9;

[0068] Step S4, repeat the above steps S1 to S3 to continue obtaining the staircase wall surface and installing the precast staircase 8.

[0069] Optionally, in one embodiment, the distance between the top plate 12 and the bottom plate 11 is two storey heights. In step S2, the construction workers can set up the formwork of the staircase between the two storey heights at one time around the two operation scaffolds 1, which can improve the construction efficiency and reduce the hoisting cost.

[0070] In one embodiment, when constructing the first floor (it can be understood that the first floor here does not refer to the first floor above ground, but the lowest floor, and its height does not correspond to one storey height either. Instead, it refers to the height corresponding after the operation platform of the staircase in the prefabricated building is placed on the lowest floor), the heights of the cross beams 91 on both sides of the scissors staircase 9 are the same. At this time, the cushion structure 16 may not be provided on the bottom surface of the bottom plate 11 of the operation scaffold 1. Before step S4, the cushion structure 16 is installed on one side of the bottom surface of the bottom plate 11 so that the cushion 160 protrudes from the edge of the bottom plate 11. In step S4, the cushion structure 16 is placed on one side cross beam 91 of the scissors staircase 9, and the other side of the bottom surface of the bottom plate 11 is placed on the upper end of the prefabricated staircase 8.

[0071] The construction method of the staircase in the prefabricated building provided by the present invention can realize the formwork erection construction of the scissors staircase 9 by means of two operation scaffolds 1. The division of multiple operation spaces 10 in each operation scaffold 1 is more conducive to construction. The two operation scaffolds 1 respectively enclose the two side floor areas, which can prevent people from falling, reduce the construction of safety protection for the edge and opening, reduce the protection steps and lower the protection cost.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
