[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 One embodiment provided by this utility model:

[0033] An assembled staircase aluminum formwork, comprising:

[0034] Side plate 1, the bottom of one side of side plate 1 is connected and fixed to one side of base plate 2 by locking connector 3. A positioning hole 4 is provided on the bottom surface of side plate 1. The inner wall of positioning hole 4 fits with the top of support threaded rod 5. Positioning hole 4 and support threaded rod 5 are engaged. Support threaded rod 5 are evenly distributed. The above structural design enables positioning hole 4 and support threaded rod 5 to be stably connected. Support threaded rod 5 can stably support and position base plate 2. Limit post 6 is provided at the top of inner wall of positioning hole 4.

[0035] The limiting post 6 fits against the inner wall of the limiting hole 7, and the limiting post 6 and the limiting hole 7 are engaged. The bottom view of the limiting post 6 and the limiting hole 7 are both square. The above structural design can limit the support threaded rod 5 and prevent the support threaded rod 5 from rotating in the positioning hole 4. The length of the limiting post 6 is not less than half the depth of the positioning hole 4, and the side length of the limiting post 6 is not less than half the diameter of the support threaded rod 5. The above structural design makes the structural strength of the limiting post 6 sufficient to stably limit the support threaded rod 5. The limiting hole 7 is opened at the top of the support threaded rod 5. The bottom end of the support threaded rod 5 is connected to the inner wall of the sleeve 8. The bottom end of the sleeve 8 is connected and fixed to the center of the top surface of the base plate 10. An anti-slip pad 11 is fixed on the ground of the base plate 10.

[0036] Side panel 1, with a horizontal template 12 and a vertical template 13 provided in the middle of one side. The horizontal template 12 is connected and fixed to the side panel 1 by a first side connector 14, and the vertical template 13 is connected and fixed to the side panel 1 by a second side connector 15. The horizontal template 12 is connected and fixed to the vertical template 13 by a longitudinal connector 16.

[0037] In one embodiment, a compression bolt 9 is threaded through the top of the side wall of the sleeve 8. The compression bolts 9 are symmetrically distributed about the center of the sleeve 8. The above structural design allows the compression bolts 9 to compress the bottom end of the support threaded rod 5. With the self-locking of the threads of the sleeve 8 and the support threaded rod 5, the support effect of the support threaded rod 5 and the sleeve 8 on the base plate 2 is guaranteed.

[0038] In one of the preferred embodiments, the sleeve 8 is threadedly connected to the bottom end of the support threaded rod 5. The front view shape of the sleeve 8 and the substrate 10 as a whole is an "丄" shape. The above structural design enables the sleeve 8 to rotate and drive the support threaded rod 5 for vertical fine adjustment to adapt to different installation environments, and the contact area between the substrate 10 and the support surface is relatively large, so the stability is relatively high.

[0039] In one of the embodiments, the horizontal templates 12 and the vertical templates 13 are alternately distributed at equal intervals. The shape of the horizontal template 12 is an "L" shape, and the front view shape of the vertical template 13 is a "匚" shape. The above structural design enables the horizontal templates 12 and the vertical templates 13 to be stably combined and have relatively high structural strength and are not easily deformed.

[0040] In one of the preferred embodiments, the end of the horizontal part of the horizontal template 12 is connected and fixed to the top end of the vertical template 13 through a longitudinal connecting member 16. The top end of the vertical template 13 is fitted to the bottom end of the bottom surface of the upper horizontal template 12, and one side of the bottom of the vertical template 13 is fitted to the vertical part of the lower horizontal template 12. The above structural design enables multiple horizontal templates 12 and vertical templates 13 to be stably combined and connected.

[0041] The working principle of the present utility model is as follows: When in use, first install the side plate 1 on one side of the bottom plate 2 through the locking connecting member 3. The other side of the bottom plate 2 is closely pressed and fitted to the wall surface at the staircase pouring position. Subsequently, as Figure 3 shown, insert the top of the support threaded rod 5 into the positioning hole 4, and the limiting column 6 at the center inside the positioning hole 4 is also inserted into the limiting hole 7 at the top of the support threaded rod 5. Then rotate the sleeve 8. The sleeve 8 uses the threaded connection relationship to push the support threaded rod 5 to move vertically upward until the anti-slip pad 11 on the bottom surface of the substrate 10 is closely pressed and fitted to the bottom support surface. Stop rotating the sleeve 8, and rotate the symmetrically distributed extrusion bolts 9 to squeeze and fix the bottom end of the support threaded rod 5, so that the support threaded rod 5, the sleeve 8, the substrate 10 and the anti-slip pad 11 stably support and position the side plate 1 and the bottom plate 2;

[0042] Subsequently, as Figure 1 shown, connect and fix one end of the horizontal template 12 and the vertical template 13 to the side plate 1 through the first side connecting member 14 and the second side connecting member 15 respectively. The other side surfaces of the horizontal template 12 and the vertical template 13 are also closely pressed and fitted to the wall surface at the staircase pouring position like the bottom plate 2. Then use the longitudinal connecting member 16 to connect and lock the end of the horizontal template 12 to the top of the vertical template 13. Then concrete pouring can be carried out through the window reserved between the bottom surface of the topmost vertical template 13 and the top surface of the bottom plate 2.
