[0040] The bottom plate 1 of the staircase formwork and the support side plates 2 form a U-shaped inclined structure. One side at the bottom end of the support side plate 2 is slidably connected with an insertion plate 3 at the bottom end of the staircase. The first positioning insertion rod 4 penetrates through the inside of the insertion plate 3 at the bottom end of the staircase, and both ends of the first positioning insertion rod 4 penetrate through 1 support side plate 2 respectively. The insertion plate 3 at the bottom end of the staircase is set as an L-shaped plate body structure.

The stair bottom end inserting plate 3 arranged at the bottom end of the stair formwork bottom plate 1 realizes the limitation of the stair length through the splicing and installation of the positioning inserting rod 1 4. The height of the bottom end of the stair bottom end inserting plate 3 is reduced according to the needs of stair pouring to facilitate the pouring of concrete. The lower supporting plate 5 arranged on one side of the stair formwork bottom plate 1 is connected by clamping through a card slot, as Figure 3 shown.

[0043] The positioning component includes:

[0044] The positioning side plate 11 is installed in the strip-shaped card slot at the upper end of the stair formwork bottom plate 1, and the positioning side plate 11 is arranged parallel to the supporting side plate 2.

[0045] A positioning bar 12 is installed on the upper end of the positioning side plate 11, the upper end of the positioning bar 12 abuts against the surface of the step template 13, and the two sides of the step template 13 are symmetrically provided with inclined openings;

[0046] The step template 13 is located on the surfaces of the two supporting side plates 2 and is equidistantly connected by snapping, and the step template 13 is set as a T-shaped plate structure;

[0047] A positioning tie bar 14 passes through the interior of the step template 13, and both ends of the positioning tie bar 14 pass through the two supporting side panels 2;

[0048] A positioning back plate 15, which is located at the bottom end of the step template 13 and is connected by clamping, and the positioning back plate 15 is set as an L-shaped plate;

[0049] The third positioning rod 16 is snap-fitted into the groove on one side of the step template 13, and the other side of the third positioning rod 16 is snap-fitted into the interior of the positioning back plate 15, and the two ends of the third positioning rod 16 are flush with the two ends of the positioning back plate 15;

[0050] In conjunction with the accompanying drawings Figures 1-6 As shown, the symmetrical strip openings at the upper end of the stair formwork bottom plate 1 provide an installation position for the positioning side panels 11. The positioning side panels 11 are assembled with the positioning strips 12 to further support the outside of the supporting side panels 2 and increase the supporting area. The positioning strips 12 are docked with the steel wires as needed and with the scaffolding at the installation location to avoid deformation of the formwork caused by the impact of pouring during the pouring process. The bottom end of the step formwork 13 is spliced ​​with the positioning back plate 15. As the positioning plug rod 3 16 is inserted into the step formwork 13 and spliced ​​with the positioning back plate 15, the positioning back plate 15 is set to increase the contact area with the supporting side panels 2. The card grooves arranged on both sides of the top of the step formwork 13 are positioned and engaged with the top of the supporting side panels 2. As the positioning pull The strip 14 is inserted so that the step formwork 13 and the supporting side panel 2 can be quickly assembled, so that the entire formwork can be cleaned and maintained after disassembly, and then used again, which not only reduces the material cost, but also reduces the impact on the environment. By setting the position of the internal slot, the entire formwork can be adjusted and customized according to different stair design requirements to achieve a personalized construction plan. The supporting structures such as the stair formwork bottom plate 1, the supporting side panel 2, the lower support plate 5, the upper support plate 7 and the positioning side panel 11 are closely combined with the set slots, providing a strong supporting force for the formwork. During the concrete pouring process, the formwork can remain stable without deformation or displacement, thereby ensuring the molding quality of the concrete.

[0051] Working principle: When using the stepped stair formwork with a card slot type positioning component, the stair formwork bottom plate 1 is installed at the stair installation position of the building in cooperation with the support side plates 2 at both ends. The lower support plate 5 and the upper support plate 7 are fixed through the penetration connection of the positioning bolt 1 6 and the positioning bolt 2 8, which is used for docking with the external metal structure to improve the overall bearing capacity. The stair bottom plug 3 installed at the bottom end of the stair formwork bottom plate 1 and the stair top plug 9 at the top end are used to limit the covering range of the concrete pouring in the stair, and the support side plates 2 are adjusted for the width of the stepped stair. The positioning side plates 11 and the positioning strips 12 are further cooperated for positioning to prevent the support side plates 2 from tilting outwards during the pouring process. As the stepped formwork 13 is spliced with the positioning back plate 15, the stability of the splicing and assembly with the surface of the support side plates 2 is increased. At the same time, the positioning back plate 15 regulates the height of the stair steps. As the positioning tie bar 14 penetrates the top end of the stepped formwork 13 and is connected to the external scaffolding position, through the card slot type positioning and assembly, the installation and disassembly are made more simple and rapid. Workers can quickly assemble and disassemble the formwork, improving the construction efficiency, reducing the labor intensity, and increasing the overall practicability.
